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 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.

Randomized Controlled Trial Clinical TrialEffects of caudal sufentanil supplemented with levobupivacaine on blocking spermatic cord traction response in pediatric orchidopexy.
Caudal block is one of the most commonly used anesthetic techniques in subumbilical and genitourinary procedures. However, traditional administration of caudal levobupivacaine was inadequate on blocking peritoneal response during spermatic cord traction. The aim of this study was to evaluate whether the addition of caudal sufentanil to levobupivacaine provided better analgesia for children undergoing orchidopexy. ⋯ In pediatric orchidopexy, the addition of sufentanil to levobupivacaine for caudal blockade offers clinical benefit over levobupivacaine alone in blocking the spermatic cord traction response.

Randomized Controlled Trial Comparative StudyComparison of Pentax-AWS Airwayscope, Airtraq and Miller laryngoscope for tracheal intubation by novice doctors during infant cardiopulmonary resuscitation simulation: a randomized crossover trial.
Recent guidelines for infant cardiopulmonary resuscitation emphasize that all rescuers should minimize interruption of chest compressions, even for endotracheal intubation. We compared the utility of the Pentax-AWS Airway Scope (AWS) with an infant-sized Intlock (AWS-I), Airtraq laryngoscope (ATQ) and Miller laryngoscope during chest compressions on an infant manikin. Twenty-three novice doctors performed tracheal intubation on an infant manikin using the AWS-I, ATQ and Miller laryngoscope, with or without chest compressions. ⋯ In AWS-I trials, all participants succeeded regardless of chest compressions. Intubation time was significantly longer with chest compressions with the Miller laryngoscope and ATQ, but not with the AWS-I. The AWS-I is an effective device for endotracheal intubation during chest compressions in infant simulations managed by novice doctors.

Randomized Controlled TrialUtility of the Pentax-AWS Airwayscope and Macintosh laryngoscope for airway management during chest compressions in 27° left-lateral tilt: a manikin simulation study of maternal cardiopulmonary resuscitation.
American Heart Association (AHA) 2010 cardiopulmonary resuscitation guidelines recommend high-quality chest compressions (minimum interruption, a pace >100 compressions/min, and a depth more than 5 cm). They propose minor changes for pregnant women: manual left deviation of the uterus or a left-lateral incline of 27°-30° to alleviate pressure on the inferior vena cava. We examined the performance of the Pentax-AWS Airwayscope (AWS) and Macintosh laryngoscope (McL) for airway management during chest compressions on a 27° left-lateral tilt (27 LLT) operating table. ⋯ The AWS is an effective tool for airway management during chest compressions in 27 LLT in a manikin, suggesting that the AWS may be a useful device for airway management during maternal resuscitation.
