Randomized Controlled Trial Clinical TrialCo-administration of midazolam decreases propofol dose during anesthesia in endoscopic laryngeal microsurgery.
Propofol is commonly used in total intravenous anesthesia (TIVA) for brief surgical procedures because it offers rapid recovery and has fewer side effects. However, concomittent use of other adjuvant agents has been considered so that the same anesthetic effects can be achieved at lower doses of propofol which is more expensive without compromising rapid recovery and increasing the adverse effects. This study was therefore designed to evaluate the co-administration of midazolam and propofol during anesthesia for endoscopic microsurgery and test its influences on the consumption of propofol and the quality of anesthesia. ⋯ Our result suggests that co-administration of midazolam and propofol in TIVA appears to be safe, effective, and economic alternative to that with propofol alone. The effects were synergic but side effects were not.

Randomized Controlled Trial Comparative Study Clinical TrialProphylaxis against acid aspiration in regional anesthesia for elective cesarean section: a comparison between oral single-dose ranitidine, famotidine and omeprazole assessed with fiberoptic gastric aspiration.
Acid aspiration syndrome is still an important cause which contributes to maternal mortality in obstetric anesthesia. In this study, we compared famotidine, ranitidine, omeprazole with placebo for prophylaxis against aspiration pneumonitis in elective Cesarean section under regional anesthesia. ⋯ Our data demonstrated that parturients under regional anesthesia were at a higher risk of aspiration pneumonitis than generally thought. Single dose of ranitidine or famotidine administered orally three hours before surgery provided a more effective means to control and neutralize gastric secretion than omeprazole in parturients.
