(Summary)
This study aimed to explore the effect of intraoperative glucose load on metabolism in patients with type 2 diabetes anesthetized with remifentanil. A total of 30 patients were enrolled and randomly allocated to one of two groups:no glucose or low-dose glucose (0.1 g/kg/h for 1 hour followed by 0.05 g/kg/h for 1 hour). Glucose, adrenocorticotropic hormone, 3-methylhistidine, insulin, cortisol, free fatty acid, ketone bodies, and creatinine were measured at several points before, during, and after general anesthesia. Glucose levels in the low-dose glucose group increased significantly at 1 and 2 hours after glucose infusion compared to their preanesthetic levels and to those in the no glucose group. Two patients in the low-dose glucose group had blood glucose levels exceeding 11.1 mmol/L. Free fatty acids, ketone bodies, and 3-methylhistidine/creatinine did not differ significantly between groups. Ketone body levels were significantly higher at 1 hour than preanesthetic levels in both groups;after 1 hour, however, they did not change in the no glucose group but significantly decreased in the low-dose glucose group. Intraoperative low-dose glucose load may suppress ketogenesis, but clinicians must consider the risk of causing hyperglycemia in patients with type 2 diabetes undergoing remifentanil-induced anesthesia.

(Summary)
AsisTIVA is total intravenous anesthesia support software for syringe pump control. It remains the only automated program to have achieved both practical and commercial viability. AsisTIVA has been certified for use at Tokushima University, Tohoku University, and at its developer institution, Fukui University. We conducted our initial anesthesia management with AsisTIVA at Tokushima University. This initial experience was successful, with no adverse effects. AsisTIVA controls propofol and remifentanil concentrations to maintain a Bispectral index of 45 and adjusts rocuronium concentrations to maintain a Train Of Four value of 1. By managing these anesthetics, AsisTIVA allows anesthesiologists to focus on other aspects of anesthesia management. Its use is expected to expand further. J. Med. Invest. 72 : 211-216, February, 2025.

(Summary)
Vagus nerve stimulation (VNS) is used to treat drug-resistant epilepsy. We report a case of intraoperative severe bradycardia and cardiac arrest during a second VNS implantation. No cases of bradycardia during the second VNS implantation have been reported. <br> The patient underwent the first VNS implantation before and experienced no intraoperative bradycardia. A mechanical error of the VNS was discovered, and the second operation was scheduled. General anesthesia was scheduled with supporting by a prophylactic pacing defibrillator to manage bradycardia during VNS. After exchanging the electrodes on the left vagus nerve, test stimulations were performed. We observed an increase in the PR interval on the electrocardiogram (ECG) during the test stimulation and severe bradycardia with cardiac arrest during the main stimulation, which required shortterm chest compressions and percutaneous pacing. After discontinuing stimulation, the pulse rate recovered immediately. We conclude that continuous ECG monitoring intraoperative is crucial, even if the first VNS implantation was uneventful.

(Summary)
Electroconvulsive therapy-induced TCM is more likely to cause cardiogenic shock than nonperioperative cases; nevertheless, it has good prognosis. Cautious reinitiation of ECT after TCM recovery is possible. Further studies are required to determine preventive measures for ECT-induced TCM.

(Summary)
We evaluated the effect of 10-min prewarming on core temperature maintenance during general anesthesia. We randomized 40 women scheduled for breast cancer surgery into 10-min Prewarming and Control groups. In the Prewarming group, a forced-air warming system was used to warm the patients at 43 for 10 min immediately before general anesthesia induction. In the Control group, the patients were kept warm using cotton thermal blankets for 10 min. We measured tympanic temperature every 15 min from anesthesia induction for 90 min. Since two patients deviated from the protocol, we used the data of 38 patients (Prewarming [n?=?18] and Control [n?=?20]). There was a significant between-group difference in changes in core temperature (P?=?0.03), including a significant difference in core temperature decrease during the first 60 min from anesthesia induction (Prewarming : -0.3 [0.3] vs. Control : -0.6 [0.2] , P=0.02). In addition, the duration of normal core temperature maintenance was significantly longer in the Prewarming group (66 [34] min vs. 39 [32] min, P?=?0.01). Ten-min prewarming decreases core temperature loss and contribute to maintaining normal core temperature during breast surgery. J. Med. Invest. 70 : 74-79, February, 2023.

Ryosuke Kawanishi, Nami Kakuta, Yoko Sakai, Yuki Hari, Hideto Sasaki, Ryo Sekiguchi and Katsuya Tanaka : Desflurane improves lung collapse more than propofol during one-lung ventilation and reduces operation time in lobectomy by video-assisted thoracic surgery: a randomized controlled trial, BMC Anesthesiology, 22, 1, 125, 2022.
(Summary)
This study evaluated whether desflurane improved lung collapse during one-lung ventilation (OLV) more than propofol, and whether it could reduce the operation time of video-assisted thoracic surgery. Sixty patients undergoing lobectomy by video-assisted thoracic surgery (VATS) were randomly assigned to general anesthesia with desflurane or propofol. Lungs were inspected by thoracoscope at 10, 30, and 60 min after initiation of OLV. After surgery, the Lung Collapse Score, a composite of lung color and volume assessments, was assigned by two clinicians blinded to the anesthetic regimen. The primary outcome was operation time. The secondary outcome included the complication rate. Of the 60 participants, 50 completed the study, 26 in Desflurane group and 24 in Propofol group. The Lung Collapse Scores at 30 and 60 min after OLV initiation were significantly better in Desflurane group than in Propofol group, and operation time was significantly shorter in Desflurane group (214 (57) min vs. 262 (72) min [mean (SD)], difference in means, -48; 95% CI, -85 to -11; P = 0.01). The incidence of multiple complications was 1/26 (3%) and 6/24 (25%) in Desflurane and Propofol group, respectively (relative risk, 0.1; 95% CI, 0.02 to 1.18; P = 0.04). Desflurane improved lung collapse during OLV and significantly shortened VATS lobectomy operation time compared to propofol in our studied patients. Desflurane resulted in fewer postoperative complications. Thus, desflurane may be an appropriate anesthetic during lobectomy by VATS requiring OLV. The study was registered with the University Hospital Medical Information Network ( UMIN000009412 ). The date of disclosure of this study information is 27/11/2012. On this date, we registered the study into UMIN; patients were included from 2013 to 2014. However, on 11/27/2015, the UMIN system administrator suggested a detailed description. Thereafter, we added it to the Randomization Unit. Despite being prospective, it was retrospectively registered on UMIN for the above reasons.

(Summary)
Malignant hyperthermia (MH) is a severe hypermetabolic disorder associated with dysregulation of calcium homeostasis and is triggered by inhalational anesthetics (isoflurane, sevoflurane, desflurane) and a depolarizing muscle relaxant (succinylcholine). We report the case of a 16-day-old infant undergoing laparoscopic surgery. The patient developed hyperthermia and hypercarbia with muscle rigidity. After the diagnosis of MH, dantrolene was administered with sufficient hydration. The patient was transferred to the pediatric intensive care unit for monitoring and treatment of acute renal injury due to myoglobinuria. Subsequently, two variants of the ryanodine receptor 1 (RYR1) gene were identified in the patient as the mutation point at c.1589G > A p.Arg530His and c.1841G > T p.Arg614Leu, which are known to be associated with MH. This was a rare case of MH in a 16-day-old infant that might be related to two RYR1 mutations inherited from the parents.
Kouhei Fukuta, Asuka Kasai, Noriko Niki, Yuki Ishikawa, Ryosuke Kawanishi, Nami Kakuta, Yoko Sakai, Yasuo M. Tsutsumi and Katsuya Tanaka : The effect of 1% glucose loading on metabolism in the elderly patients during remifentanil-induced anesthesia: A randomized controlled trial, BMC Anesthesiology, 20, 1, 143, 2020.
(Summary)
Previous studies showed that remifentanil-induced anesthesia can inhibit surgical stress response in non-diabetic adult patients and that low-dose glucose loading during anesthesia may attenuate fat catabolism. However, little is known about the influence of glucose loading on metabolism in elderly patients, whose condition may be influenced by decreased basal metabolism and increased insulin resistance. We hypothesized that, in elderly patients, intraoperative low glucose infusion may attenuate the catabolism of fat without causing harmful hyperglycemia during remifentanil-induced anesthesia. Elderly, non-diabetic patients scheduled to undergo elective surgery were enrolled and randomized to receive no glucose (0G group) or low-dose glucose infusion (0.1 g/kg/hr. for 1 h followed by 0.05 g/kg/hr. for 1 h; LG group) during surgery. Glucose, adrenocorticotropic hormone (ACTH), 3-methylhistidine (3-MH), insulin, cortisol, free fatty acid (FFA), creatinine (Cr), and ketone body levels were measured pre-anesthesia, 1 h post-glucose infusion, at the end of surgery, and on the following morning. A total of 31 patients (aged 75-85) were included (0G, n = 16; LG, n = 15). ACTH levels during anesthesia decreased significantly in both groups. In the LG group, glucose levels increased significantly after glucose loading but hyperglycemia was not observed. During surgery, ketone bodies and FFA were significantly lower in the LG group than the 0G group. There were no significant differences in insulin, Cr, 3-MH, and 3-MH/Cr between the two groups. Remifentanil-induced anesthesia inhibited surgical stress response in elderly patients. Intraoperative low-dose glucose infusion attenuated catabolism of fat without inducing hyperglycemia. This study has been registered with the University hospital Medical Information Network Center (http://www.umin.ac.jp/english/). UMIN000016189. The initial registration date: January 12th 2015.

(Summary)
Two types of amniotic fluid embolism (AFE) have been described : cardiopulmonary collapse type and disseminated intravascular coagulation (DIC) type, with the latter proposed as uterine type. This report describes a healthy 28-year-old woman who developed AFE during a cesarean section. Because of a previous cesarean section, the patient underwent an elective cesarean section, under combined spinal-epidural anesthesia, at 38 weeks of pregnancy. She began coughing 5 minutes after delivery of the fetus, subsequently becoming unconscious and developing glossoptosis and bradycardia. Her blood pressure decreased to 76/43 mmHg, and AFE was suspected. Her uterus was atonic, and she experienced persistent noncoagulant bleeding, with a final blood loss of 6300 ml. Considerable blood transfusion was required. The patient survived, and she and her baby were discharged without any sequelae on the eighth postoperative day. This patient met the Japanese criteria for clinical AFE, with an obstetrical DIC score of 21 meeting the criteria for obstetrical DIC. Early diagnosis and treatment likely resulted in patient survival. J. Med. Invest. 67 : 207-210, February, 2020.

(Summary)
Background and aims : Severe aortic stenosis (AS) has been normally treated with surgical aortic valve replacement (AVR) whereas recently, transcatheter aortic valve implantation (TAVI) has been introduced as a minimally invasive operation for patients with high surgical risk and frailty. In this study, we have evaluated postoperative physical function and nutrition intake in the patients following AVR and TAVI. Methods : This prospective observational study involved 9 patients with surgical aortic valve replacement (AVR) and 7 patients with transcatheter aortic valve implantation (TAVI). Body composition was measured one day prior surgery, postoperative day (POD) 1, POD 3, POD 5 and POD 7. Hand grip strength, calf circumference and gait speed were measured one day before surgery and on the day of discharge. Results : Skeletal muscle was significantly decreased in AVR patients at postoperative day 3 and 7, while there was no change in TAVI patients. Patients with TAVI showed higher dietary intake after surgery compared to patients with AVR, and they maintained hand grip strength and calf circumference at discharge. Conclusions : In elderly patients with AS, TAVI can improve post-operative recovery maintaining nutritional status and physical function even. J. Med. Invest. 67 : 139-144, February, 2020.

(Summary)
The purpose of this study was to assess the accuracy and reliability of a continuous blood glucose monitoring system (artificial endocrine pancreas; STG-55, Nikkiso, Tokyo, Japan) during pediatric cardiopulmonary bypass surgery. Twenty-five pediatric patients scheduled to undergo cardiovascular surgery with cardiopulmonary bypass (age 4 months to 11 years; body weight 5.6-59.7 kg) were enrolled. The glucose sensor line of the artificial endocrine pancreas was connected to the venous side of the cardiopulmonary bypass circuit and used for continuous blood glucose monitoring. We obtained 192 samples for blood gas assessment from the cardiopulmonary bypass circuit, and i-STAT (Abbott, East Windsor, NJ, USA) was used for conventional blood glucose assessment. The accuracies of continuous glucose measurements (STG-55) and conventional intermittent glucose measurements (i-STAT) during cardiopulmonary bypass were compared by means of Clarke error grid analysis. The results were divided into five zones, A, B, C, D, and E, and 78.6% of paired measurements were in zone A, while 21.4% were in zone B. We confirmed that the results of this continuous blood glucose monitoring system for cardiopulmonary bypass during pediatric cardiovascular surgery were highly reliable. An artificial endocrine pancreas may facilitate the safe use of intensive insulin therapy during pediatric cardiovascular surgery.

(Summary)
Study Objective : the incidence of postoperative nausea and vomiting (PONV) following single-injection intraarticular anesthesia was compared to that following continuous epidural anesthesia. Design : Prospective, double-blind, randomized study. Setting : University-affiliated teaching hospital. Patients : Forty-eight patients finally participated in this study, and each group contained twenty-four patients. Interventions : Patients scheduled to undergo lower limb surgery under general anesthesia were randomly allocated into two groups, to receive either single-injection intraarticular or continuous epidural anesthesia for postoperative analgesia. Measurements : The incidence and severity of PONV, complete response rates (i.e., no vomiting or rescue antiemetic use), and pain scores were recorded 2, 24, and 48 h postoperatively. Main results : No significant differences between groups were observed in the incidence and severity of PONV, rescue antiemetic use, or complete response rate at any of the time points, but only the use of rescue analgesics was significantly less in continuous epidural anesthesia group during the 2-24h postoperative period (P=0.04). Conclusion : While the use of single-injection intraarticular anesthesia following lower limb surgery did not prevent PONV more than continuous epidural anesthesia in this study, the intraarticular technique still provides greater simplicity, safety, and cost-effectiveness.

(Summary)
Methylmalonic acidemia (MMA) is a metabolic disorder of organic acids and is characterized by the accumulation of methylmalonic acids. The patient was a 19-year-old female diagnosed with severe MMA at 3 days of age, who was scheduled for renal replacement therapy. Preoperatively, there was no evidence of metabolic acidosis or electrolyte abnormalities. Glucose was administered preoperatively following a 6-h fast. Anesthesia was administered using thiamylal, remifentanil, rocuronium, and sevoflurane. After tracheal intubation, the patient underwent an ultrasound-guided bilateral rectus sheath block with ropivacaine. A drop in blood sugar level was treated with 5% glucose. Extubation was performed after intravenous administration of sugammadex. We report the anesthetic management of a patient with MMA using a combination of general anesthesia and rectus sheath block.

(Summary)
It is well known that the programmed intermittent epidural bolus (PIEB) technique effectively provides epidural anesthesia in labor. This randomized double-blind trial compared the postoperative analgesic efficacy of PIEB with that of continuous epidural infusion (CEI) in patients undergoing gynecological surgery under combined general-epidural anesthesia. Patients undergoing open gynecological surgery under combined general-epidural anesthesia were randomized at a 1 : 1 ratio to receive PIEB or CEI. In the PIEB group, the pump delivered 4L ropivacaine 0.2% plus fentanyl 2 g/mL every hour. In the CEI group, the pump delivered the same solution at a rate of 4L/h. In both groups, additional 4L boluses of ropivacaine 0.2% plus fentanyl 2 g/mL were provided, when necessary, by patient-controlled epidural analgesia after surgery. The primary outcome was the total ropivacaine dose 40 hours after surgery. The secondary outcomes were the number of PCEA boluses and postoperative pain (evaluated on an 11-point numerical rating scale) 3, 24, and 48 hours after surgery. In total, 57 patients were randomized ( = 28 and 29 in the PIEB and CEI groups, resp.). The two groups differ significantly in terms of the total ropivacaine dose 40 hours after surgery (mean (standard deviation): 155.38 (4.55) versus 159.73 (7.87)L, = 0.016). Compared to the CEI group, the PIEB group had significantly lower numerical rating scale scores 3 hours (median [lower-upper quartiles]: 0 [0-0.5] versus 3 [0-5.5], = 0.002), 24 hours (1 [0-2] versus 3 [1-4], = 0.003), and 48 hours (1 [0-2] versus 2 [2-3.5], = 0.002) after surgery. PIEB was better than CEI in terms of providing postoperative analgesia after open gynecological surgery under combined general-epidural anesthesia.

(Summary)
We investigated the effectiveness of the ClearSight system for hemodynamic management during kidney transplantation for a recipient. The recipient was to receive a kidney transplant from his mother under general anesthesia. We used continuous noninvasive finger-cuff-based monitoring of blood pressure, provided by the ClearSight system, and stroke volume variation to predict fluid responsiveness. We used of a balanced anesthetic technique and stringent monitoring standards to ensure a successful outcome for the patient. This case demonstrated that ClearSight has the potential to improve patient monitoring in hemodynamically stable patients who received kidney transplantation under general anesthesia. J. Med.

(Summary)
Robot-assisted laparoscopic radical prostatectomy (RALRP) is commonly performed in the surgical treatment of prostate cancer. However, the steep Trendelenburg position (25) and pneumoperitoneum required for this procedure can sometimes cause hemodynamic changes. Although blood pressure is traditionally monitored invasively during RALRP, the ClearSight system (BMEYE, Amsterdam, The Netherlands) enables a totally noninvasive and simple continuous blood pressure and cardiac output monitoring based on finger arterial pressure pulse contour analysis. We therefore investigated whether noninvasive continuous arterial blood pressure measurements using the ClearSight system were comparable to those obtained invasively in patients undergoing RALRP. Ten patients scheduled for RALRP with American Society of Anesthesiologists physical status I-II were included in this study. At each of the seven defined time points, noninvasive and invasive blood pressure measurements were documented and compared in each patient using Bland-Altman analysis. Although the blood pressure measured with the ClearSight system correlated with that measured invasively, a large difference between the values obtained by the two devices was noted. The ClearSight system was unable to detect blood pressure accurately during RALRP, suggesting that blood pressure monitoring using this device alone is not feasible in this small patient population.

(Summary)
Postoperative nausea and vomiting (PONV) occur in 30-50% of patients undergoing general anesthesia and in 70-80% of high PONV risk patients. In this study, we investigated the efficacy of fosaprepitant, a neurokinin-1 (NK1) receptor antagonist, compared to ondansetron, a selective 5-hydroxytryptamine type 3 (5-HT3) receptor antagonist, in moderate to high PONV risk patients from our previous randomized controlled trials. Patients (171 patients from 4 pooled studies) with the Apfel simplified score ≥ 2 and undergoing general anesthesia were randomly allocated to receive intravenous fosaprepitant 150 mg (NK1 group, = 82) and intravenous ondansetron 4 mg (ONS group, = 89) before induction of anesthesia. Incidence of vomiting was significantly lower in the NK1 group compared to the ONS group 0-2, 0-24, and 0-48 hours after surgery (2 versus 17%, 2 versus 28%, and 2 versus 29%, resp.). However, no significant differences in PONV, complete response, rescue antiemetic use, and nausea score were observed between groups 0-48 hours after surgery. In moderate to high PONV risk patients, fosaprepitant decreased the incidence of vomiting and was superior to ondansetron in preventing postoperative vomiting 0-48 hours after surgery.

(Summary)
The aim of this work was to investigate the effect of oral carbohydrate with amino acid [oral nutritional supplement (ONS)] solution on oxidative stress in healthy persons. Fourteen healthy volunteers were segregated into control and ONS groups. Volunteers in the ONS group ingested 250 ml of Arginaid Water (Nestle Japan, Tokyo, Japan) in the evening before the experiment and at 7:00 am on the day of the experiment. Volunteers in the control group fasted after dinner and drank only water until 7:00 am on the day of the experiment. In both groups, blood was collected at 9:00 am. The serum total oxidant levels and antioxidant capacity were assessed by d-ROMs (derivatives of reactive oxygen metabolites) test and BAP (biological antioxidant potential) test, respectively. In the ONS group, the serum d-ROMs level was significantly lower than in the control group (297 ± 43 and 327 ± 41 U.CARR, respectively, p = 0.018), while the serum BAP level was significantly higher than the control group (2410 ± 432 and 1979 ± 397 µmol/l, respectively, p = 0.005). The OXY level of Arginaid Water was much higher than preOp drink (Nutricia, Ireland). In conclusion, our study showed that an ONS with arginine loading could decrease oxidative stress and increase antioxidant capacity in healthy volunteers.

(Summary)
This study investigated plasma concentrations of substance P (SP) in patients undergoing general anesthesia (GA) and postoperative nausea and vomiting (PONV). This prospective, observational, cohort study included 23 patients who underwent scheduled surgery under general anesthesia. Blood was collected from the radial artery at predetermined time points (15-30 mins prior anesthesia, 15-30 mins after surgery/GA, and 24 h after surgery). PONV, SP concentrations, risk factors, and analgesics used were measured. Nine of 23 patients experienced PONV. In patients without PONV, SP concentrations significantly decreased ( < 0.0001) at the end of surgery/GA, compared to baseline, and recovered at 24 h after surgery/GA (452.9 ± 146.2 vs. 666.9 ± 176.5 vs. 580.7 ± 168.6 pg/mL, respectively), whereas SP levels were unchanged during surgery/GA and increased at 24 hours after surgery ( = 0.020) in patients with PONV (726.1 ± 167.8 vs. 655.8 ± 168.0 vs. 779.7 ± 220.7 pg/mL, respectively). These finding suggest that SP levels may be utilized as an objective marker for PONV.

(Summary)
During perioperative fasting, lipid metabolism gradually increases, resulting in free fatty acids (FFA) and/or ketone bodies. Suppression of surgical stress by remifentanil may allow the safe administration of glucose infusions, avoiding both hyperglycemia and ketogenesis. The effects of glucose infusion on glucose and lipid metabolism were therefore investigated in patients undergoing minor surgery with remifentanil anesthesia. Thirty-four patients were randomized 1 : 1 to receive no glucose (0G group) or low-dose glucose (0.1 g/kg/h for 1 h followed by 0.05 g/kg/h for 1 h; LG group). The concentrations of glucose, adrenocorticotropic hormone (ACTH), 3-methylhistidine (3-MH), insulin, cortisol, FFA, creatinine (Cr), and ketone bodies were measured before anesthetic induction, 1 and 2 h after glucose infusion, at the end of surgery, and the next morning. The concentrations of cortisol and ACTH decreased during surgery in both groups when compared with the concentrations before anesthesia and at the end of surgery (P < 0.05). Glucose and insulin concentrations were significantly higher in the LG than in the 0G group at 1 and 2 h after infusion. No patient experienced hyperglycemia. The concentrations of FFA and ketone bodies were lower in the LG than in the 0G group during surgery, but there were no significant between group differences in 3-MH/Cr. Infusion of low-dose glucose attenuated fat catabolism without causing hyperglycemia, indicating that infusion of low-dose glucose during remifentanil-induced anesthesia may be safe for patients.

(Summary)
A PediaSat™ oximetry catheter (PediaSat: Edwards Lifesciences Co., Ltd., Irvine, CA, U. S. A.), which facilitates continuous measurement of central venous oxygen saturation (ScvO2), may be useful for surgery for pediatric congenital heart disease. We used PediaSat during a bidirectional Glenn shunt. The patient was a 13-month-old boy. Under a diagnosis of left single ventricle (pulmonary atresia, right ventricular hypoplasia, atrial septal defect) and residual left aortic arch/left superior vena cava, a modified right Blalock-Taussig shunt was performed. Cyanosis deteriorated, so a bidirectional Glenn shunt was scheduled. After anesthesia induction, a 4.5 Fr double-lumen (8 cm) PediaSat was inserted through the right internal jugular vein for continuous ScvO2 monitoring. Furthermore, the probe of a near-infrared, mixed blood oxygen saturation-measuring monitor was attached to the forehead for continuous monitoring of the regional brain tissue mixed blood oxygen saturation (rSO2) (INVOS™ 5100C, Covidien; Boulder, CO, U. S. A.). Blockage of the right pulmonary artery and right superior vena cava decreased the oxygen saturation, ScvO2, and rSO2, but increased the central venous pressure. Although changes in ScvO2 were parallel to those in rSO2, the former showed more marked changes. A combination of ScvO2 and rSO2 for monitoring during Glenn shunt may be safer.

(Summary)
For anesthetic management during renal transplantation, it is necessary to maintain the blood flow and function of the transplanted kidney by performing massive fluid management and stabilizing blood pressure. We report anesthetic management for renal transplantation with a less-invasive circulatory monitoring system (Edwards Life Sciences Co., Ltd., Irvine, California, U.S.A.). In November 2010, renal transplantation was started in our hospital, and performed in 6 patients. In the first patient, fluid/circulatory management was conducted by connecting a standard arterial line and a standard central venous (CV) line. In the second patient, a FloTrac(TM) system and a standard CV line were used. In the third patient, a standard arterial line and a PreSep(TM) CV Oximetry Catheter were used. In the fourth and fifth patients, a FloTrac(TM) and a PreSep(TM) were used. In the latest patient, FloTrac(TM) and PreSep(TM) were connected to an EV1000(TM) Clinical Platform for fluid/circulatory management. The establishment of high-visibility monitors was useful for evaluating the condition and confirming the effects. As there are marked changes in hemodynamics, the CV pressure, which has been used as a parameter of fluid management, is not reliable in renal failure patients with a high incidence of cardiovascular complications. Advances in noninvasive circulatory monitoring with dynamic indices may improve the safety of anesthetic management during renal transplantation.

(Summary)
We describe anesthetic management of a patient with airway stenosis due to a tracheal tumor involving the carina. A 68-year-old man developed dyspnea and was scheduled for YAG laser surgery under general anesthesia. Awake fiberoptic intubation was selected for anesthesia induction, and percutaneous cardiopulmonary support (PCPS) was ready to be established prior to induction of anesthesia. Anesthesia was maintained with remifentanil (0.05 microg x kg(-1) x min(-1)) and propofol (2 mg x kg(-1) x hr(-1)), and spontaneous breathing was preserved throughout the surgical procedure. The operation was completed successfully without any adverse events, and PCPS was not used. In this patient, preservation of spontaneous breathing using remifentanil was found to be useful for airway management.

(Summary)
Post-operative nausea and vomiting (PONV) remains the most frequently reported patient complaint after anesthesia. Aprepitant is the first neurokinin-1(NK1) receptor antagonism available for use as an antiemetic. We investigated whether aprepitant can effectively decrease PONV in patients undergoing laparoscopic gynecological surgery. Sixty four patients receiving general anesthesia for laparoscopic gynecological surgery were randomly assigned to either receive a preoperative dose of 80 mg aprepitant or no drug. Efficacy was assessed in 2 and 24 hours after surgery. Primary and secondary endpoints were analyzed for the time intervals 0-2 hours (acute phase) and 2-24 hours (delayed phase). Vomiting, nausea, use of rescue anti-emetic, and visual analog scale (VAS) were assessed. Nausea was assessed on a 4-point scale, from 0 to 3. Sixty patients participated in the study. At acute phase, PONV was present in both control and NK1 group and were 63% and 43% respectively. The severity of nausea was much less in the NK1 group. PONV prevalence at delayed phase was present in control but absent in NK1 group 27% vs. 0%, respectively. The amount of pain medication used by patients in the NK1 group was significantly less for diclofenac and pentazocine suggesting increase pain tolerance. Neurokinin-1 receptor antagonism effectively lowered PONV increased pain tolerance, and expedited recovery in patients undergoing laparoscopic gynecological surgery.

(Summary)
We experienced anesthetic management of a patient with Becker muscular dystrophy. He had advanced dilated cardiomyopathy and high serum CK in the preoperative examinations. Anesthesia was planned to avoid triggering malignant hyperthermia or rhabdomyolysis and hemodynamic changes. Propofol, remifentanil and a minimum dose of rocuronium bromide were used for anesthetic induction and maintainance. Arterial pressure, cardiac output and stroke volume variation were monitored by Flotrac sensor. There were no adverse events observed during the anesthetic management. In conclusion, total intravenous anesthesia with the administration of rocuronium and circulatory monitoring by Flotrac sensor could be safe and efficient for anesthetic management of patients with Becker muscular dystrophy.

(Summary)
Volatile anesthetics, such as isoflurane, reverse glucose-induced inhibition of pancreatic adenosine triphosphate-sensitive potassium (K(ATP)) channel activity, resulting in reduced insulin secretion and impaired glucose tolerance. No previous studies have investigated the effects of intravenous anesthetics, such as propofol, on pancreatic K(ATP) channels. We investigated the cellular mechanisms underlying the effects of isoflurane and propofol on pancreatic K(ATP) channels and insulin secretion.
We evaluated Disposable Crystal Laryngoscope Blades in terms of preventing infection. Most anesthesiologists were satisfied with the view offered by the Disposable Crystal Laryngoscope Blade; however more force is necessary to lift the epiglottis during intubation. It may be more difficult to use by residents, inexperienced anesthesiologist, or emergency medical technicians, although the Disposable Crystal Laryngoscope blade is useful for preventing infection.

(Summary)
Angelman syndrome is a hereditary disease described by Angelman. The clinical features of Angelman syndrome are characterized by mental retardation, puppet-like ataxia, easily excitable personality, seizures, paroxysmal laughter, strabismus and macroglossia. A 4-year-old girl with Angelman syndrome underwent strabismus repair under general anesthesia. Anesthesia was slowly induced with sevoflurane in oxygen and maintained with air, oxygen, propofol and remifentanil. Tracheal intubation was performed after administration of rocuronium. During and after anesthesia, no adverse events regarding circulatory and respiratory systems occurred. However, this case demonstrates that it is necessary to pay attention to airway troubles including the difficulty of tracheal intubation, management of body temperature and chronotropic action or respiratory depression by anesthetic agents.

(Summary)
Post-operative nausea and vomiting(PONV)remains the most frequently reported patientscomplaint after anesthesia, and for patients, it is of greater concern than postoperative pain. PONVhas four main risk factors including : female gender, history of PONV or motion sickness, nonsmoking,and the use of postoperative opioids. Primary control of nausea and vomiting arises from the centralpattern generator for vomiting located in the medulla oblongara.Traditionally, the most common anti-emetics used to treat PONV include serotonin 5-hydroxytryptamine type3antagonists such as ondansetron, corticosteroids, like dexamethasone,or droperidol, which is a neuroleptic. However, these anti-emetics are not completely reliable andonly reduce the incidence of PONV by∼26%. Adding additional anti-emetics could further lowerthe incidence of PONV.PONV can result in several post-surgical complications. Neurokinin-1(NK-1)receptors are foundin gastrointenstinal vagal afferents and within the central nervous system vomiting reflex pathways.NK-1receptors are activated by Substance P, which is a regulatory peptide and preferred endogenousligand.We investigated whether NK-1antagonism can effectively diminish PONV in patients undergoinglaparoscopic gynecological surgery. Forty two patients were randomized into two groups : NK-1group which received an oral NK-1antagonist, aprepitant at80mg, and a control that did not receiveany anti-emetic. PONV incidence at2hours was present in both control and NK-1groups and was81% and52%, respectively. At24hours PONV was present in the control group, but was absentin the NK1group(27% and0%，respectively).PONV is associated with dissatisfaction after anesthesia and surgery, can result in several postsurgicalcomplications. NK-1receptor antagonism effectively lowered PONV, and expedited recoveryin patients undergoing laparoscopic gynecological surgery.
