Randomized Controlled Trial Comparative StudyComparisons of two different doses of fentanyl for procedural analgesia during epidural catheter placement: a double-blind prospective, randomized, placebo-controlled study.
The purpose of this study was to investigate the effect of fentanyl on analgesic properties and respiratory responses during an epidural procedure. Sixty patients premedicated with oral brotizolam 0.25 mg were allocated to receive procedural analgesia with saline or 25 or 50 μg of fentanyl. Five minutes after administration, an epidural procedure was started. ⋯ Seven of 20 cases in the 50 μg fentanyl group needed oxygen administration because of a decreased SpO₂ value (<94%). No cardiovascular complications were observed in any group during the entire study period. Thus, intravenous fentanyl at a dose of 25 μg provides effective procedural analgesia without the risk of hypoxemia during an epidural procedure in a patient with preanesthetic medication.

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 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 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.
