Randomized Controlled Trial Clinical Trial
Efficacy of ultrasound imaging in obstetric epidural anesthesia.
To assess the clinical use of ultrasonographic localization of the epidural space, and to evaluate the clinical efficacy of ultrasound diagnostics in obstetric anesthesia. ⋯ The clinical use of ultrasound for epidural catheter placement may improve regional anesthesia. The use of ultrasound resulted in superior quality in all measured endpoints.

Randomized Controlled Trial Comparative Study Clinical Trial
Nitrous oxide does not improve sevoflurane induction of anesthesia in adults.
To compare the characteristics of sevoflurane induction with and without the addition of nitrous oxide (N(2)O) using tidal breathing inhalation induction without priming of the breathing circuit. ⋯ The addition of N(2)O does not confer any clinically significant advantage in this method of sevoflurane induction in adults.

Multicenter Study Clinical Trial
Predicting recovery from deep neuromuscular block by rocuronium in children and adults.
To compare the response to motor nerve stimulation at a rate of 1 Hz after 50 Hz tetanus [posttetanic count (PTC)] and 2 Hz for 2 seconds [train-of-four (TOF)] in children and adults during spontaneous recovery from blockade caused by rocuronium. ⋯ Children recover faster than adults from neuromuscular blockade after administration of 1 mg x kg(-1) rocuronium. The relationship between PTC and time to first response to TOF is exponential both in children and adults during recovery from neuromuscular blockade caused by rocuronium.

Randomized Controlled Trial Clinical Trial
Preoperative administration of controlled-release oxycodone for the management of pain after ambulatory laparoscopic tubal ligation surgery.
To examine the analgesic efficacy of administering controlled-release (CR) oxycodone 10 mg before elective ambulatory laparoscopic tubal ligation surgery. ⋯ The preoperative administration of CR oxycodone 10 mg is an effective analgesic technique in the management of pain following ambulatory laparoscopic tubal ligation surgery, and may facilitate earlier postoperative discharge.

To compare cardiac output (CO) as measured by the arterial thermodilution technique using only a central venous catheter and an arterial catheter inserted into the axillary artery, with conventional CO measurement with thermodilution using a pulmonary artery (PA) catheter (PAC). ⋯ In critically ill patients, in whom the measurement of CO is required, arterial thermodilution, using a central vein and the axillary artery is accurate and reproducible.
