Randomized Controlled Trial Comparative Study Clinical Trial
Which induction drug for cesarean section? A comparison of thiopental sodium, propofol, and midazolam.
To determine maternal and neonatal effects of three different induction drugs (thiopental sodium, propofol, and midazolam) for cesarean section. ⋯ Thiopental still remains the first-choice induction drug for cesarean section. The slow induction time with midazolam may put the mother at risk for pulmonary inhalation. A plane of anesthesia that may risk awareness and potential neonatal depression is the main drawback of the two newer induction drugs.

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.

Regional anesthetic techniques for children have recently enjoyed a justified resurgence in popularity. Intraoperative blockade of the neuraxis, whether by the spinal or epidural route, provides excellent analgesia with minimal physiologic alteration and, with an indwelling catheter, can provide continuous pain relief for many days postoperatively. ⋯ Although some practitioners contend that a regional block on an already anesthetized child adds to the risk of the general anesthetic itself, in experienced hands the risks are negligible and the benefits dramatic. In this review of caudal and lumbar epidural and subarachnoid blockade in infants and children, anatomy, physiologic alterations, and pharmacology pertinent to the three types of neuraxial blockade are described, with the aim of providing the practicing anesthesiologist with the foundation needed to perform these blocks with relative confidence.

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.

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.
