Randomized Controlled Trial Clinical Trial
Using the laryngeal indices caliper to predict difficulty of laryngoscopy with a Macintosh #3 laryngoscope.
(1) To evaluate a device of the authors' design, the laryngeal indices caliper, which quantitates the position of the anterior edges of the larynx relative to the upper teeth and the external auditory canals; (2) to determine how relative laryngeal position affects ease of direct laryngoscopy with a Macintosh #3 laryngoscope. ⋯ (1) Laryngeal tilt is a good predictor of difficulty of laryngoscopy with a Macintosh #3 laryngoscope; (2) the laryngeal indices caliper is a simple pocket device to measure LT indirectly.

Randomized Controlled Trial Comparative Study Clinical Trial
Propofol versus midazolam for monitored sedation: a comparison of intraoperative and recovery parameters.
To compare intraoperative and recovery parameters in patients who received either propofol infusion (PI), propofol bolus (PB), or midazolam bolus (MZ) for sedation. ⋯ The PI, PB, and MZ groups all gave excellent sedation for patients undergoing surgical procedures with local anesthesia. Amnesia was greatest with midazolam, and recovery was more rapid with propofol.

Randomized Controlled Trial Clinical Trial
Using the bubble inclinometer to measure laryngeal tilt and predict difficulty of laryngoscopy.
To evaluate a simple device, the bubble inclinometer, to measure degrees of laryngeal tilt (LT) for predicting difficulty of direct laryngoscopy using a Macintosh #3 laryngoscope. ⋯ The bubble inclinometer accurately and reproducibly measures relative LT, and the anterior tilt of the larynx directly correlates with the ability to see the laryngeal opening during direct laryngoscopy with a Macintosh #3 laryngoscope.

Randomized Controlled Trial Clinical Trial
The laryngeal lift: a method to facilitate endotracheal intubation.
To assess the efficacy of the "laryngeal lift" maneuver in improving laryngoscopic visualization to facilitate endotracheal intubation. ⋯ The laryngeal lift should be part of the anesthesiologists' armamentarium in helping the laryngoscopist who is faced with Grades II, III, IV, and V laryngoscopic views to enhance visualization of the larynx and thus facilitate endotracheal intubation.

Randomized Controlled Trial Comparative Study Clinical Trial
Spinal or systemic analgesia after extensive spinal surgery: comparison between intrathecal morphine and intravenous fentanyl plus clonidine.
To compare two different methods of postoperative analgesia after extensive spinal fusion. ⋯ This study shows that there is a major risk of respiratory depression with a single intrathecal dose of morphine 0.3 mg to control postoperative pain after scoliosis surgery. Systemic clonidine-fentanyl may be a possible approach to the postoperative pain treatment of this surgery.
