Here we report successful rapid-sequence inubation with the McGRATH MAC videolaryngscope (McGRATH) in the face to face sitting position for a patient with severe ileus and restricted mouse opening. A 46-year-old woman with advanced bladder cancer had developed ileus. Ileus tube and octreotide did not relieve her symptoms, and emergency colostomy was planned. ⋯ First an anesthesiologist stood at face to face position to the patients, and the second anesthesiologist kept the head of the patient from the cranial side. After thiamylal and fentanyl administration, cricoid pressure was applied by the third anesthesiologist. Under the guide of the McGRATH's monitor, we could successfully insert the 7.0 mm internal diameter tracheal tube with a stylet uneventfully in the face to face sitting position.

Droperidol is an effective antiemetic, but its use is limited because of the warning of drug-induced QT prolongation. Some reports showed that low-dose droperidol does not significantly probing QT interval. This study was aimed to determine the effect of low-dose droperidol (1.25 and 2.5 mg) on QTc interval, and the interaction among droperidol, propofol and sevoflurane. ⋯ Droperidol's effect on QTc prolongation was shown at the dose of 2.5 mg but not 1.25 mg. This prolongation effect was offset by propofol, and was unchanged by sevoflurane.

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.
