Randomized Controlled Trial Clinical Trial
[Changes in intracuff pressure of endotracheal tubes permeable or resistant to nitrous oxide and incidence of postoperative sore throat].
We assessed the nitrous oxide (N2O) gas-barrier properties of a new endotracheal tube cuff, the Profile Soft-Seal Cuff (Resistant: R) (Sims Portex, Kent, UK). ⋯ The difference of cuff pressure is considered due to the difference in cuff compliance.

Randomized Controlled Trial Clinical Trial
[Effects of perfusion pressure on cerebral blood flow and oxygenation during normothermic cardiopulmonary bypass].
Central nervous system dysfunction after cardiopulmonary bypass (CPB) is an important cause of morbidity and mortality after cardiac surgery. Perfusion pressure (PP) during CPB could be one of the important determinants of cerebral blood flow (CBF). The objective of the present study was to determine the effect of PP on CBF and cerebral oxgenation during normothermic CPB. ⋯ These results suggest that maintaining high PP is benefical for CBF during normothermic CPB.

Case Reports
[Withdrawal syndrome in a critically ill child after sedation with midazolam and fentanyl].
A 7-year-old girl suffered from withdrawal syndrome with systemic convulsion after sedation with midazolam and fentanyl. She had a history of severe accidental alkaline esophagitis, and under went polysurgeries. This time, she was scheduled to receive reconstruction of the esophagus with small intestine in order to resolve esophageal stenosis. ⋯ There was no evidence of obvious organic central nervous system abnormality. We suspected withdrawal syndrome, and gradual decrease of midazolam and fentanyl prevented her from going into withdrawal syndrome. We have to pay attention to withdrawal syndrome when heavy and long sedation with midazolam and fentanyl was employed and the drugs were then tapered and discontinued.

Case Reports
[Anesthetic management for cleft palate plasty in a patient with Pierre-Robin syndrome].
A girl (15 months-old) with Pierre-Robin Syndrome was scheduled for cleft palate plasty. She had a past history of difficulty feeding, mild airway obstruction during sleeping and mental retardation. After induction of anesthesia with an inhalational anesthetic technique, conventional tracheal intubation was impossible. ⋯ Airway obstruction then improved gradually. In this case, LMA was a valuable device as a guide for the tracheal intubation. Because airway obstruction after extubation is a common complication in a patient with Pierre-Robin syndrome, we need to observe the patient closely.

A 58-year-old man was scheduled for laryngomicrosurgery for treatment of large laryngeal polyps. Although awake induction was initially attempted to prevent airway obstruction, his vocal cords could not be visualized. ⋯ The operation was performed without any complications. We conclude that a PFT tube is useful for endotracheal intubation in a patient with large laryngeal polyps.
