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 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.

Use of single-dose and continuous interscalene brachial plexus block (ISB) are gaining widespread popularity. When compared with general anesthesia, ISB has been reported to provide superior postoperative analgesia with fewer side effects, and it is associated with greater patient satisfaction. Anatomical landmarks are readily identifiable, which contributes to the ease of performing this block. In the future, we anticipate increased use of continuous interscalene catheters or injection of biodegradable local anesthetic impregnated microspheres to provide prolonged perioperative outpatient analgesia.

To assess the impact of a new postanesthesia care unit (PACU) on intensive care unit (ICU) utilization, hospital length of stay, and complications following major noncardiac surgery. ⋯ Increased availability of PACU beds resulted in reduced utilization of ICU resources without compromising patient care after major noncardiac surgery.

We report two cases of overdoses of intramuscular midazolam used as a premedication. Both cases had no resedation or complications, but the accidents happened as a result of a resident and nurse's lack of experience with midazolam. The intramuscular doses, given at four times the normal quantity, fortunately caused no harm in our cases. However, the situations suggest that we should carefully check the dosage and review the correct procedures, even when using a drug that is considered to be familiar with most practitioners.
