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.
