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.

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.

Randomized Controlled Trial Clinical Trial
Respiratory acidosis prolongs, while alkalosis shortens, the duration and recovery time of vecuronium in humans.
To determine the effects of respiratory acidosis and alkalosis by mechanical ventilation on the onset, duration, and recovery times of vecuronium. ⋯ In humans, duration and recovery times of vecuronium are prolonged in respiratory acidosis and shortened in respiratory alkalosis.

Randomized Controlled Trial Clinical Trial
Effects of adding midazolam on the postoperative epidural analgesia with two different doses of bupivacaine.
To investigate the interaction of midazolam with different doses of bupivacaine, by comparing the analgesic, sedative, and amnesic effects of continuous epidural midazolam with two different doses of bupivacaine. ⋯ Adding midazolam increased not only analgesic but also sedative effect with increasing dose of bupivacaine in a postoperative continuous epidural administration.
