Randomized Controlled TrialThe interaction of antiemetic dose of droperidol with propofol on QT interval during anesthetic induction.
We investigated the effect of low-dose droperidol on heart rate-corrected QT (QTc) interval and interaction with propofol. ⋯ We found that saline or 1.25 mg droperidol did not prolong QTc interval, whereas 2.5 mg droperidol prolonged the QTc interval significantly, and that propofol injection counteracted the prolongation of the QTc interval induced by 2.5 mg droperidol.

Randomized Controlled TrialEffect of nitrous oxide inhalation on pain after propofol and rocuronium injection.
This prospective, double-blind, placebo-controlled study was designed to determine the efficacy of nitrous oxide (N(2)O) in alleviating the pain that followed sequential injection of propofol and rocuronium. ⋯ Pretreatment with inhaled N(2)O can reduce the pain associated with propofol and rocuronium injection. Moreover, N(2)O (with or without lidocaine) is more effective than lidocaine alone in reducing rocuronium-related withdrawal reactions associated with sequential injection of propofol and rocuronium.

Randomized Controlled TrialEfficacy of endotracheal lidocaine administration with continuous infusion of remifentanil for attenuating tube-induced coughing during emergence from total intravenous anesthesia.
Although attenuation of tube-induced coughing is necessary in specific types of surgery, the best method for such attenuation is still unclear. We studied the combined intervention of endotracheal lidocaine and intravenous remifentanil compared to intravenous remifentanil alone with respect to coughing during emergence from anesthesia. ⋯ This study is consistent with the finding that endotracheal lidocaine administration and continuous infusion of remifentanil before extubation is useful to prevent coughing on emergence from anesthesia.

Randomized Controlled TrialPreoperative peritonsillar infiltration of dexamethasone and levobupivacaine reduces pediatric post-tonsillectomy pain: a double-blind prospective randomized clinical trial.
Preoperative corticosteroids reduce post-tonsillectomy morbidities. The present study was performed to compare the effect of peritonsillar dexamethasone infiltration to intravenous injection together with peritonsillar levobupivacaine infiltration before tonsillectomy on postoperative pain in children. ⋯ Addition of dexamethasone to levobupivacaine for preoperative peritonsillar infiltration has better postoperative analgesic effects than i.v. dexamethasone combined with peritonsillar levobupivacaine infiltration in children.

Randomized Controlled TrialApplication of PEEP using the i-gel during volume-controlled ventilation in anesthetized, paralyzed patients.
This prospective, randomized trial was designed to assess whether the i-gel supraglottic airway device is suitable for volume-controlled ventilation while applying positive end-expiratory pressure (PEEP) of 5 cmH(2)O under general anesthesia. It was believed that this device might improve arterial oxygenation. ⋯ The use of an i-gel during PEEP application at 5 cmH(2)O did not increase the incidence of a significant air leak, and a PEEP of 5 cmH(2)O failed to improve arterial oxygenation during controlled ventilation in healthy adult patients.
