Randomized Controlled Trial Comparative Study Clinical Trial
Comparing the efficacy of prophylactic metoclopramide, ondansetron, and placebo in cesarean section patients given epidural anesthesia.
To compare the relative efficacy of prophylactic metoclopramide, ondansetron, and placebo in nonemergent cesarean section patients given epidural anesthesia intraoperatively and for the first 24-hour period after delivery. ⋯ In cesarean section patients given epidural anesthesia, prophylactic ondansetron, 4 mg IV, is more efficacious and has a higher patient satisfaction than that with metoclopramide, 10 mg IV, or placebo in preventing nausea and achieving complete responses during intraoperative period and the first 24-hour postdelivery period. However, there is no difference between ondansetron and metoclopramide in reducing frequency of vomiting. Prophylactic ondansetron 4 mg IV is more effective in preventing nausea than vomiting.

Randomized Controlled Trial Clinical Trial
Absorption of lidocaine during aspiration anesthesia of the airway.
To determine the optimal solution to use when anesthetizing the airway by aspiration of lidocaine. ⋯ This technique produced anesthesia of the airway to the carina, safely, suitable for awake intubation, in 94 of 95 patients. The use of 1% lidocaine, 0.2 to 0.3 mL. kg(-1), so that the volume is 10 to 20 mL, is recommended.

Randomized Controlled Trial Clinical Trial
Structured preoperative patient education for patient-controlled analgesia.
To investigate the effectiveness of a structured preoperative education program in patients receiving patient-controlled analgesia (PCA). ⋯ Structured preoperative PCA education did not affect patient outcome. The early improvement in patient satisfaction was minimized by continued education and pain team supervision during the rest of the postoperative period.

Randomized Controlled Trial Clinical Trial
Tracheal intubation through the laryngeal mask airway using a gum elastic bougie: the effect of head position.
To determine the effect of head position on success of tracheal intubation through a Laryngeal Mask Airway (LMA) using a gum elastic bougie. ⋯ This technique cannot be recommended as an alternative to direct laryngoscopy following a failed intubation.

To quantify the impact on peak airway pressure of pressure-controlled and volume-controlled ventilation during Laryngeal Mask Airway (LMA) use. ⋯ Pressure-controlled rather than volume-controlled ventilation can improve the effectiveness of mechanical ventilation in patients with high airway pressure.
