(要約)
Despite the requirement for meticulous management of cesarean anesthesia, no study has explored the impact of novice trainee anesthesiologists in this field. This study assessed challenges in neuraxial anesthesia for cesarean sections and compared outcomes between novice and senior anesthesiologists. We retrospectively analyzed 446 cesarean sections with neuraxial anesthesia. The primary objective was to evaluate the impact of anesthesiologists' experience on the time required to administer neuraxial anesthesia and whether maternal body mass index (BMI) influenced this relationship. Secondary objectives included examining maternal hemodynamic variability, operative details, and newborn outcomes relative to the anesthesiologist's experience. Novice anesthesiologists required a significantly longer time to perform neuraxial anesthesia (24.9 [7.1] min vs. 18.2 [7.0] min, P<0.001) than their senior counterparts. A significant interaction was observed between anesthesiologist experience and maternal BMI on the time to administer neuraxial anesthesia (P=0.017), with a moderate correlation between BMI and administration time for novices (r=0.50, P<0.001) and only a slight correlation for seniors (r=0.17, P=0.001). Experience level did not significantly affect intraoperative hemodynamics, Apgar scores, or umbilical cord blood gas analyses. The effect of maternal BMI on the difficulty of performing neuraxial anesthesia in parturients can be more pronounced for novice anesthesiologists than for experienced ones. Despite requiring more time to perform neuraxial anesthesia, novice anesthesiologists do not significantly affect maternal hemodynamics or newborn distress during obstetric anesthesia, provided that they are under the supervision of experienced anesthesiologists.
Rikako Takahashi, Yoko Sakai, Michiko Kinoshita, Yako Matsumoto, Yoshimi Nakaji and Katsuya Tanaka : Quantitative and calculated estimated blood loss in cesarean deliveries for twin and singleton pregnancies: a retrospective analysis, Journal of Anesthesia, Vol.38, No.5, 666-673, 2024.
(要約)
This study retrospectively assessed blood loss during cesarean deliveries for twin and singleton pregnancies using two distinct methods, quantitative estimation measured during cesarean sections and hematocrit-based calculated estimation. We included scheduled cesarean deliveries for twin or singleton pregnancies at 34 weeks of gestation. Quantitative blood loss was recorded based on the blood volume in the graduated collector bottle and by weighing the blood-soaked textiles during cesarean sections. The blood loss was calculated using the change in hematocrit levels before and after the cesarean delivery. We evaluated 403 cases including 44 twins and 359 singletons. Quantitative blood loss during cesarean section was significantly higher in twin pregnancies than that in singleton pregnancies (1117 [440] vs 698 [378] mL; p < 0.001). However, no significant differences were observed in the calculated blood loss between the two groups on the day after delivery (487 mL [692 mL] vs 507 mL [522 mL]; p = 0.861). On post-delivery days 4-5, twin pregnancies were associated with a significantly higher calculated blood loss than singleton pregnancies (725 [868] mL vs 444 [565] mL, p = 0.041). Although a significant moderate correlation between quantitative and calculated blood loss was observed in singleton pregnancies (r = 0.473, p < 0.001), no significant correlation was observed between twin pregnancies (r = 0.053, p = 0.735). Quantitative blood loss measurements during cesarean section may be clinically insufficient in twin pregnancies. Incorporating blood tests and continuous assessments are warranted for enhanced blood loss evaluation, especially in twin pregnancies, owing to the risk of persistent bleeding.

(要約)
Electroconvulsive therapy (ECT) is highly effective for severe psychiatric disorders; however, short seizure durations may lead to ineffective therapy. This retrospective study aimed to examine the risks and benefits of switching to ketamine anesthesia to augment seizure durations during an acute course of ECT. We included 33 patients who underwent ketamine anesthesia due to suboptimal seizures during an acute course of ECT. We assessed seizure duration, stimulus dose, hemodynamic variability, and postseizure complications before and after switching to ketamine. Age was significantly associated with suboptimal seizures during ECT (P = 0.040). After switching to ketamine, 32 patients (97%) experienced prolonged seizure duration. Ketamine significantly prolonged both electroencephalogram and motor seizure durations with a mean difference of 34.6 seconds (95% confidence interval [CI], 26.4-42.7 seconds; P < 0.001) and 26.6 seconds (95% CI, 19.6-33.6 seconds; P < 0.001), respectively. It also significantly reduced stimulus dose (mean difference, -209.5 mC [95% CI, -244.9 to -174.1 mC]; P < 0.001). In addition, maximum changes in systolic blood pressure and heart rate during ECT sessions significantly increased with ketamine (mean difference, 27.2 mm Hg [95% CI, 12.0-42.4 mm Hg; P = 0.001]; 25.7 beats per minute [95% CI, 14.5-36.8 beats per minute; P < 0.001], respectively). Patients reported more headaches with ketamine (P = 0.041). Our results provide evidence that ketamine as an alternative anesthetic can augment seizure durations in specific patients experiencing suboptimal seizures during an acute course of ECT. However, its use requires greater attention to circulatory management and postseizure complications.

(要約)
Ephedrine is a mixed α- and β-agonist vasopressor that is frequently used for the correction of hypotension during general anesthesia. β-responsiveness has been shown to decrease with age; therefore, this study aimed to determine whether aging would reduce the pressor effect of ephedrine on hypotension during general anesthesia. Seventy-five patients aged ≥ 45 years were included in this study, with 25 patients allocated to each of the three age groups: 45-64 years, 65-74 years, and ≥ 75 years. All patients received propofol, remifentanil, and rocuronium for the induction of general anesthesia, followed by desflurane and remifentanil. Cardiac output (CO) was estimated using esCCO technology. Ephedrine (0.1 mg/kg) was administered for the correction of hypotension. The primary and secondary outcome measures were changes in the mean arterial pressure (MAP) and CO, respectively, at 5 min after the administration of ephedrine. RESULTS: The administration of ephedrine significantly increased MAP (p < 0.001, mean difference: 8.34 [95% confidence interval (CI), 5.95-10.75] mmHg) and CO (p < 0.001, mean difference: 7.43 [95% CI, 5.20-9.65] %) across all groups. However, analysis of variance revealed that the degree of elevation of MAP (F [2, 72] = 0.546, p = 0.581, η = 0.015 [95% CI, 0.000-0.089]) and CO (F [2, 72] = 2.023, p = 0.140, η = 0.053 [95% CI, 0.000-0.162]) did not differ significantly among the groups. Similarly, Spearman's rank correlation and multiple regression analysis revealed no significant relation between age and the changes in MAP or CO after the administration of ephedrine. The administration of ephedrine significantly increased MAP and CO; however, no significant correlation with age was observed in patients aged > 45 years. These findings suggest that ephedrine is effective for the correction of hypotension during general anesthesia, even in elderly patients. UMIN-CTR (UMIN000045038; 02/08/2021).

(要約)
Although it is important to recognize gender disparities in publishing to achieve gender diversity, women's authorship in Japan remains unclear. Therefore, this study aimed to investigate the percentage and analyze the trends of articles authored and published in anesthesiology journals by Japanese female authors. The genders of the first and last authors affiliated with Japanese institutions were surveyed in the Journal of Anesthesia (JA) (1990, 1995, and 2000-2022) and 11 international anesthesiology journals (2010-2022). We included 845 and 819 original research articles from JA in the analyses of the first and last authors, respectively. The proportion of female first authors significantly increased from 41 (11.7%) out of 351 before 2009 to 119 (24.1%) out of 494 after 2010 (p < 0.001). The proportion of female last authors was 11 (3.3%) out of 335 before 2009 and 22 (4.5%) out of 484 after 2010, respectively, with no significant difference (p = 0.470). We included 624 and 572 original research articles from international anesthesiology journals in the analyses of first and last authors, respectively. Among these, there were 134 (21.5%) and 23 (4.0%) female first and last authors, respectively. These proportions in international anesthesiology journals did not significantly differ from those in JA (p = 0.334, p = 0.789, respectively). The percentage of female first authors has increased, commensurate with the percentage of female anesthesiologists. However, the percentage of female last authors has not increased and remains low in Japan.

(要約)
MAP decreased after induction of anesthesia in both groups, without significant differences between the groups (- 41.1 [16.4] mmHg and - 42.8 [10.8] mmHg in remimazolam and propofol groups, respectively; mean difference: 1.7 [95% confidence interval: - 8.2 to 4.9]; p = 0.613). Furthermore, HR, CO, and SV decreased after induction in both groups, without significant differences between the groups. Remimazolam group had significantly shorter time until loss of consciousness than propofol group (1.7 [0.7] min and 3.5 [1.7] min, respectively; p < 0.001). However, MAP, HR, CO, and SV were not significantly different between the groups despite adjusting time until loss of consciousness as a covariate. Seven (35%) and 11 (55%) patients in the remimazolam and propofol groups, respectively, experienced hypotension (MAP < 65 mmHg over 2.5 min), without significant differences between the groups (p = 0.341).

(要約)
Neuronal intranuclear inclusion disease (NIID) is a progressive neurodegenerative disease with diverse clinical manifestations, including dementia and muscle weakness. We summarize anesthetic considerations in reporting general anesthesia for a 58-year-old man with bladder dysfunction and cerebellar ataxia who was diagnosed with NIID. The patient developed postinduction hypotension relevant to autonomic neuropathy. The potential risks, such as prolonged reaction to neuromuscular blocking agent, postoperative delirium, and worsening of NIID-related symptoms, were also considered. The responsiveness to anesthetics may vary widely from case t case. As the number of NIID cases increases, a better understanding of NIID is needed.

(要約)
Takotsubo cardiomyopathy, also known as stress-induced cardiomyopathy, is a disease in which the patient exhibits transient, reversible left ventricular dysfunction that is triggered by physical or emotional stress. Prolongation of QT interval, a risk factor for arrhythmia and sudden death, has been reported to be prevalent among patients with Takotsubo cardiomyopathy and is also observed in those with severe anorexia nervosa. In this report, we describe the rare case of a 30-year-old female patient with anorexia nervosa who developed Torsades de Pointes associated with Takotsubo cardiomyopathy during emergence from general anesthesia for emergency exploratory laparotomy.

(要約)
Activation of the mitochondrial calcium-activated potassium (mKCa) channel reportedly confers resistance to myocardial ischemic stress. However, the role of the mKCa channel in postconditioning induced by volatile anesthetic remains unclear. Male Japanese white rabbits underwent coronary artery occlusion for 30 min followed by reperfusion for 3 h. Volatile anesthetic, isoflurane, was administered at 3 min prior to reperfusion for 5 min. Rabbits were injected with the mKCa channel blocker, iberiotoxin, or the mKCa channel opener, NS1619, at 8 min prior to reperfusion. Myocardial infarct size and the area at risk (AAR) were measured at the end of the experiment. Isoflurane significantly reduced infarct size (23.0 ± 9.8% of the AAR, P<0.05) compared with the control (44.0 ± 9.1%). Iberiotoxin abolished the cardioprotective impact of isoflurane (43.0 ± 11.6%), while iberiotoxin alone exerted no effect on infarct size (45.0 ± 9.5%). NS1619 and isoflurane/NS1619 both significantly reduced infarct size (21.0 ± 10.3% and 19.0 ± 8.8%, respectively, P<0.05 vs control group), but isoflurane/NS1619 showed no additional benefits compared with isoflurane alone. These results indicate that activation of the mKCa channel contribute isoflurane-induced postconditioning.

(要約)
We investigated the effects of a novel method of anesthesia combining propofol and volatile anesthesia on the incidence of postoperative nausea and vomiting in patients undergoing laparoscopic gynecological surgery. Patients were randomly divided into three groups: those maintained with sevoflurane (Group S; n = 42), propofol (Group P; n = 42), or combined propofol and sevoflurane (Group PS; n = 42). We assessed complete response (no postoperative nausea and vomiting and no rescue antiemetic use), incidence of nausea and vomiting, nausea severity score, vomiting frequency, rescue antiemetic use, and postoperative pain at 2 and 24h after surgery. The number of patients who exhibited a complete response was greater in Groups P and PS than in Group S at 0-2h (74%; 76% and 43%; respectively, p = 0.001) and 0-24h (71%; 76%, and 38%; respectively, p < 0.0005). The incidence of nausea at 0-2h (Group S = 57%; Group P = 26% and Group PS = 21%; p = 0.001) and 0-24h (Group S = 62%; Group P = 29% and Group PS = 21%; p < 0.0005) was also significantly different among groups. However, there were no significant differences among groups in the incidence or frequency of vomiting or rescue antiemetic use at 0-24h. Combined propofol and volatile anesthesia during laparoscopic gynecological surgery effectively decreases the incidence of postoperative nausea.

(要約)
Cardiac protection by volatile anesthetic-induced preconditioning and ischemic preconditioning have similar signaling pathways. Recently, it was reported that augmentation of protein modified with O-linked -N-acetylglucosamine (O-GlcNAc) contributes to cardiac protection. This study investigated the role of O-GlcNAc in cardiac protection induced by anesthetic-induced preconditioning. O-GlcNAc-modified proteins were visualized by immunoblotting. Tolerance against ischemia or reperfusion was tested in vivo (n = 8) and in vitro (n = 6). The opening of the mitochondrial permeability transition pore (mPTP) upon oxidative stress was examined in myocytes treated with calcein AM (n = 5). Coimmunoprecipitation and enzymatic labeling were performed to detect the mitochondrial protein responsible for the mPTP opening. Isoflurane treatment and the consequent augmentation of O-GlcNAc concentrations reduced the infarct size (26 ± 5% [mean ± SD], P < 0.001) compared with the control. The protective effect of O-GlcNAc was eliminated in the group pretreated with the O-GlcNAc transferase inhibitor alloxan (39 ± 5%, P < 0.001). Myocyte survival also showed the same result in vitro. Formation of the mPTP was abrogated in the isoflurane-treated cells (86 ± 4%, P < 0.001) compared with the control and alloxan-plus-isoflurane-treated cells (57 ± 7%, P < 0.001). Coimmunoprecipitation and enzymatic labeling studies revealed that the O-GlcNAc-modified, voltage-dependent anion channel restained the mPTP opening. Isoflurane induced O-GlcNAc modification of mitochondrial voltage-dependent anion channel. This modification inhibited the opening of the mPTP and conferred resistance to ischemia-reperfusion stress.

(要約)
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.

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.
