(Summary) We should be aware of the history of tracheostomy, especially at high tracheostomy sites, even in the absence of respiratory symptoms as risk factors for dynamic inspiratory airway collapse concomitant with subglottic stenosis contributing to repeated respiratory failure after extubation.

(Summary) Background : Neuroblastoma is the most common extracranial solid tumor of childhood. Although the prognosis of neuroblastoma is relatively good, newborns less than two months of age with stage 4S neuroblastoma may present with aggressive hypoxia and restrictive respiratory impairment due to abdominal compartment syndrome. Case presentation : Two-month-old girl, height of 63 cm and body weight of 10 kg. She was diagnosed as neuroblastoma with Stage 4S. Because she was suffered from refractory hypoxemia and restrictive respiratory impairment due to abdominal compartment syndrome induced by multiple liver metastasis and massive ascites, she was transferred to our ICU. Her trachea was intubated and ventilated with assist/controlled mode, driving pressure 22 cmH2O, positive end-expiratory pressure(PEEP)8 cmH2O, fraction of inspiratory oxygen(FIO2)1.0, but tidal volume was obtained only 3.2 mL/kg and PaO2/FIO2 ratio of 55 mmHg. Therefore, we insert esophageal sensor and monitored esophageal pressure to performed transpulmonary pressure guided PEEP titration. When we changed PEEP from 8 to 15 cmH2O so that the end-expiratory transpulmonary pressure achieving 0 to 5 cmH2O, her oxygenation(PaO2/FIO2 ratio : 55 to 178 mmHg)and respiratory compliance(1.4 to 3.0 mL/cmH2O)were dramatically improved. Her respiratory condition was further stabilized by ascites puncture and radiotherapy, and the patient was extubated successfully on the 25th ICU day. Conclusions : Although pediatric neuroblastoma with stage 4S may induce severe respiratory efficiency, the responsiveness of treatment for neuroblastoma is promising. Multimodal treatments including optimal ventilator management such as transpulmonary pressure -guided PEEP titration contributes to improved patient's prognosis.

(Summary) Background : We herein report the use of independent lung ventilation (ILV) for managing acute allograft rejection after single-lung transplantation (SLT) for end-stage emphysema. Case presentation : A 54-year-old woman was transferred to our hospital with severe hypoxemia and respiratory distress due to unilateral lung disease with diffuse alveolar damage in the right donor lung associated with acute allograft rejection and with hyperinflation of the left native lung due to emphysema. She was unresponsive to immunosuppressive medications and conventional ventilation strategies, so different ventilator settings for each lung were required. A double-lumen endotracheal tube (DLT) was inserted, and ILV was initiated. The right lung was ventilated with high positive end-expiratory pressure (PEEP), intended for lung recruitment, and the left lung was ventilated with lung protective strategies using a low tidal volume and low levels of PEEP to avoid hyperinflation. Two days later, her lung function was dramatically improved, and the DLT was replaced with a single-lumen endotracheal tube. Gas exchange was maintained, and she was successfully weaned from mechanical ventilation on intensive-care unit day 15. Conclusions : ILV appears to be effective and safe for managing acute allograft rejection after SLT for emphysema. J. Med. Invest. 69 : 323-327, August, 2022.

(Summary) Background : Laryngomalacia is a congenital abnormality of the larynx that commonly occurs in children and rarely in adults. We report the first case of acquired laryngomalacia mainly due to postoperative seizure and central pontine myelinolysis after scheduled craniotomy. Case presentation : A 69-year-old man was admitted to the hospital for elective craniotomy for craniopharyngioma. After the surgery, he developed refractory seizure and required intubation and mechanical ventilation in the intensive-care unit (ICU). After treatment for the seizure, he was extubated. However, immediately after extubation, he developed stridor and respiratory retraction. We performed fiberoptic laryngoscopy and confirmed that the epiglottis had collapsed into the posterior wall of the pharynx during inspiration, which was suspected to be laryngomalacia. He received invasive mechanical ventilation for two days following re-extubation. After the second extubation, he developed stridor again due to acquired laryngomalacia. Six days later, his respiratory condition had worsened, and he received re-intubation and tracheostomy. After ICU discharge, central pontine myelinolysis was diagnosed by magnetic resonance imaging. Conclusions : Adult-onset laryngomalacia is a rare cause of upper airway obstruction but should be considered as a cause of postoperative extubation failure. We should not delay performing fiberoptic laryngoscopy to evaluate this pathology and provide optimal treatment. J. Med. Invest. 69 : 316-319, August, 2022.

(Summary) Purpose : High-flow nasal cannula oxygen therapy (HFNC) is a new type of non-invasive respiratory support for acute respiratory failure patients. However, patients receiving HFNC often develop sleep disturbances. We therefore examined whether dexmedetomidine could preserve the sleep characteristics in patients who underwent HFNC. Patients and Methods : This was a pilot, randomized controlled study. We assigned critically ill patients treated with HFNC to receive dexmedetomidine (0.2 to 0.7 µg / kg / h, DEX group) or not (non-DEX group) at night (9:00 p.m. to 6:00 a.m.). Polysomnograms were monitored during the study period. The primary outcomes were total sleep time (TST), sleep efficiency and duration of stage 2 non-rapid eye movement (stage N2) sleep. Results : Of the 28 patients who underwent randomization, 24 were included in the final analysis (12 patients per group). Dexmedetomidine increased the TST (369 min vs. 119 min, p = 0.024) and sleep efficiency (68% vs. 22%, P = 0.024). The duration of stage N2 was increased in the DEX group compared with the non-DEX group, but this finding did not reach statistical significance. The incidences of respiratory depression and hemodynamic instability were similar between the two groups. Conclusions : In critically ill patients who underwent HFNC, dexmedetomidine may optimize the sleep quantity without any adverse events. J. Med. Invest. 69 : 266-272, August, 2022.
