Malignant hyperthermia occurred 10 hours after surgery in a 72-year-old man who had received emergency laparoscopic cholecystectomy for severe acute cholecystitis with cholelethiasis. He had a high fever (39.4 degrees C) with liver damage before surgery. Anesthesia was induced with propofol and fentanyl and maintained with sevoflurane and epidural block using ropivacaine. ⋯ He had hypoxic brain damage, but was dischanged from the hospital after tracheostomy on the 150th hospital day. From his clinical course, especially decrease in body temperature by dantrolene, he was suspected to have developed malignant hyperthermia. We should consider malignant hyperthermia when patient had a severe high fever postoperatively.

The purpose of this study was to examine the hemodynamics and bispectral index score during lower abdominal surgery under balanced anesthesia with the two different combination doses of desflurane and remifentanil. ⋯ The patients could be anesthetized adequately during lower abdominal surgery under balanced anesthesia with the two different combination doses of desflurane and remifentanil.

Intraoperative monitoring of train-of-four (TOF) response is recommended to avoid inadequate dose of muscle relaxant and its antagonist. We have standardized monitoring of TOF response at the end of surgery in all the patients undergoing general anesthesia with rocuronium since October 2013. ⋯ We conclude that standardization of TOF response at the end of surgery reduces dose of sugammadex in patients with slight residual neuromuscular block though the dose in patients under deep muscle relaxation seems to be insufficient.

Case Reports
[A Case of Repetitive Cardiac Arrest due to Coronary Vasospasm after Sugammadex Administration].
A 58-year-old man with no history of cardiac disease was scheduled for a cerebral aneurysm clipping surgery. Anesthesia was administered with propofol, rocuronium, fentanyl, and remifentanil. At the end of the surgery, extubation was performed 3 min after the administration of 200 mg sugammadex, along with a simultaneous blood-pressure decrease with ST elevation on lead II. ⋯ An acetylcholine provocation test performed later showed positive results. We suspect sugammadex to be the cause of coronary vasospasm, because the time courses of the two cardiac arrest episodes after sugammadex administration were very similar. Therefore, clinicians should consider sugammadex as one of the causative agents of cardiac arrest in the operating room.

Complete tracheal ring causes congenital tracheal stenosis in neonates and infants. We have to prevent further tracheal stenosis in perioperative period. This is a case report of an infant with congenital tracheal stenosis due to complete tracheal ring who underwent primary cleft lip closure under general anesthesia. ⋯ He was discharged on 8 POD without complication. CT scan and its integrated 3 D image of the trachea were useful to understand the approximate structure. However endoscopic examination allowed more detailed structure-measurement below glottis.
