Randomized Controlled Trial Comparative Study Clinical Trial
Comparison of hemodynamics, recovery profile, and early postoperative pain control and costs of remifentanil versus alfentanil-based total intravenous anesthesia (TIVA).
To compare hemodynamics, recovery profiles, early postoperative pain control and costs of total intravenous anesthesia (TIVA) with propofol and remifentanil and propofol and alfentanil. ⋯ Both remifentanil and alfentanil provided a reasonably rapid and reliable recovery. The remifentanil-based TIVA was associated with high intraoperative cost and early postoperative pain, but it allowed a more rapid respiratory recovery.

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.

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.
