Randomized Controlled Trial Comparative Study Clinical Trial
Effect of laryngeal mask airway on esophageal motility during general anesthesia.
To determine whether the Laryngeal Mask Airway (LMA) triggers the pharyngo-esophago-gastric reflex during general anesthesia by comparing the esophageal motility of patients with the LMA and endotracheal tube (ETT) in place. ⋯ During the general anesthetic period before the arousal phase in this study, a LMA does not provoke significantly different esophageal peristalsis compared with an ETT. Thus, the LMA is unlikely to stimulate the pharyngo-esophago-gastric reflex during that period.

Randomized Controlled Trial Comparative Study Clinical Trial
A comparison of the effects of droperidol and the combination of droperidol and ondansetron on postoperative nausea and vomiting for patients undergoing laparoscopic cholecystectomy.
To compare the prophylactic antiemetic efficacy of the combination of ondansetron and droperidol with that of droperidol alone in patients undergoing elective laparoscopic cholecystectomy. ⋯ Patients who received the combination of droperidol and ondansetron experienced less severe nausea compared with patients who received droperidol alone.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
A comparison of the remifentanil and fentanyl adverse effect profile in a multicenter phase IV study.
To compare the frequency of adverse effects of remifentanil and fentanyl in a large and diverse patient population. ⋯ In the doses used, both remifentanil and fentanyl have a similar frequency of adverse effects except for the higher frequency of hypotension associated with the use of remifentanil.
