Randomized Controlled Trial Comparative Study Clinical Trial
Dose of prophylactic intravenous ephedrine during spinal anesthesia for cesarean section.
To compare the incidence of maternal hypotension associated with spinal anesthesia for cesarean section when 10-, 15-, or 20-mg prophylactic boluses of intravenous (IV) ephedrine are used. ⋯ In the conditions of this study, a single bolus of IV ephedrine with doses of either 15 or 20 mg decreased significantly the incidence of maternal hypotension as compared to a single 10-mg bolus of ephedrine.

Randomized Controlled Trial Clinical Trial
Transcranial Doppler ultrasonography with induction of anesthesia and neuromuscular blockade in surgical patients.
To evaluate the cerebral vascular effects of cis-atracurium and rocuronium given after thiopental induction of anesthesia. ⋯ cis-Atracurium and rocuronium, administered after thiopental, do not produce clinically relevant changes in cerebral blood flow velocity.

To assess the responses to a survey asking anesthesiologists to report their clinical practice patterns for postoperative nausea and vomiting (PONV) prophylaxis. These practice patterns data may be useful for understanding how to optimize the decision to provide PONV prophylaxis. ⋯ We found a wide range of PONV prophylaxis management patterns. This variation in clinical practice may reflect uncertainty about the efficacy of available interventions, or differences in practitioners' clinical judgment and beliefs about how to treat PONV. Some therapies with proven benefit for PONV may be underused. Our results may be useful for designing studies aimed at determining the impact on PONV rates when physicians develop and implement guidelines for PONV prophylaxis.

Randomized Controlled Trial Comparative Study Clinical Trial
A double-blind, randomized comparison of low-dose rocuronium and atracurium in a desflurane anesthetic.
To compare the neuromuscular and hemodynamic effects of rocuronium and atracurium when administered during a desflurane-based anesthetic. ⋯ Rocuronium at a dose of 0.45 mg/kg possesses a fairly rapid onset of neuromuscular blockade and has short:intermediate duration of action when used with a desflurane anesthetic. This quality makes it a desirable drug for operations of relatively short duration. Rocuronium at a dose of 0.45 mg/kg has a faster onset and shorter duration than atracurium, at 0.5 mg/kg, when used with a desflurane anesthetic.

Randomized Controlled Trial Comparative Study Clinical Trial
Commercial propofol solutions: is the more expensive also the more effective?
To compare the efficacy and safety of four commercial propofol solutions marketed in Israel. ⋯ Diprivan, Recofol, Diprofol, and Propofol Abbott are equally effective as anesthesia induction drugs for dilation and curettage, with a similar incidence of adverse effects. Because cost limitations have become a significant factor in medical care, the choice of drug in this group should be based solely on cost considerations.
