Randomized Controlled Trial Comparative StudyEvaluation of tracheal intubation in several positions by the Pentax-AWS Airway Scope: a manikin study.
In emergency situations, rescuers must occasionally secure the airway while the patient is in a restricted position rather than in the ideal supine position. We hypothesized that the Pentax-AWS Airway Scope (AWS) may be useful for emergent tracheal intubation in such positions. ⋯ Although tracheal intubations with AWS in all five positions tested were successful, intubation with the patient in the Sitting, Right-LT, and Prone positions was more difficult and required more time than that in the Supine position.

Randomized Controlled TrialLocal warming at injection site helps alleviate pain after rocuronium administration.
Various strategies have been proposed to reduce discomfort of pain after rocuronium injection. These studies have shown pretreatment of drugs such as fentanyl and lidocaine to be effective. In a prospective randomized study, we evaluated whether pretreatment with local warming at injection site using an air-warming device could effectively alleviate pain induced by rocuronium. ⋯ Application of warmth over the vascular access prior to rocuronium administration effectively reduces injection-related pain.

Randomized Controlled TrialQuality of lidocaine analgesia with and without midazolam for intravenous regional anesthesia.
Midazolam has analgesic effects mediated by gamma aminobutyric acid-A receptors. This study was designed to evaluate the effect of midazolam on anesthesia and analgesia quality when added to lidocaine for intravenous regional anesthesia (IVRA). ⋯ Addition of midazolam to lidocaine for IVRA improves anesthesia quality and enhances intraoperative and postoperative analgesia without causing side effects.

Randomized Controlled TrialThe effect of injection speed on the spinal block characteristics of hyperbaric bupivacaine 0.5% in the elderly.
The purpose of this prospective, randomized, double-blind study was to compare anesthetic characteristics after two speeds of intrathecal injection of hyperbaric bupivacaine in elderly patients. ⋯ An eightfold difference in speed of intrathecal injection of 0.5% hyperbaric bupivacaine did not affect the clinical characteristics of spinal anesthesia in elderly patients undergoing transurethral surgery.

Randomized Controlled TrialLidocaine spray 10 min prior to intubation: effects on postoperative sore throat.
A sore throat is the most frequent adverse side effect of general anesthesia. The purpose of this study was to compare the different types and timing of lidocaine application based on the effectiveness of reducing postoperative sore throat (POST) after endotracheal intubation. In group A, 8% lidocaine was sprayed on laryngopharyngeal structures immediately before intubation, and the distal ends of the endotracheal tubes (ETTs) were lubricated with 2% lidocaine gel. ⋯ In 527 patients, 28.2% reported POST at 24 h following extubation. Statistically significant differences in the incidence of POST were found only between group E (16.0%) and each of the other groups (28.4-38.5%), except for group B (26.5%). In conclusion, 8% lidocaine spray significantly reduced the incidence of POST if it was sprayed on laryngopharyngeal structures 10 min prior to endotracheal intubation.
