Randomized Controlled Trial Clinical TrialOral slow release dextromethorphan premedication provides a pethidine spare effect on posthemorrhoidectomy pain management.
In our previous study, we had demonstrated that intramuscular (i.m.) dextromethorphan (DM) could provide a preemptive analgesic effect and improve postoperative pain management. Regrow is a long-duration slow-release oral dextromethorphan available for clinical use with good patient compliance. The present study was designed to examine whether oral regrow may also offer the same preemptive analgesic effect as i.m. DM does in postoperative pain management. ⋯ This study revealed that premedication of oral regrow 240 mg provided a preemptive analgesic effect, thus reducing the severity of postoperative pain and pethidine requirement in post-hemorrhoidectomy patients.

Randomized Controlled Trial Clinical TrialEffect of intravenous midazolam premedication on postoperative nausea and vomiting after cholecystectomy.
Several drugs and techniques have been used to reduce the incidence of postoperative nausea and vomiting (PONV). However PONV continues to be a common postoperative complication. Midazolam premedication in pediatric patients has been reported to reduce the incidence of PONV. In the present study the effect of intravenous midazolam premedication on the incidence and severity of PONV was investigated in a sample of adult patients undergoing anesthesia for cholecystectomy. ⋯ The results of this study suggest the effectiveness of prophylactic intravenous midazolam premedication to reduce the incidence and severity of postoperative nausea and vomiting. Possible mechanisms for this effect of midazolam may be GABA receptor antagonism, inhibition of dopamine release, and anxiolytic effects.

Risk factors associated with postoperative sore throat after tracheal intubation: an evaluation in the postanesthetic recovery room.
Postoperative sore throat after tracheal intubation is an unpleasant and distressing experience to patients. The aim of the study was to carry out a large-scale search for the risk factors of postoperative sore throat in patients undergoing endotracheal general anesthesia. ⋯ Five risk factors related to postoperative sore throat were identified in our study.

Case ReportsApplication of wire-guided endobronchial blocker for one-lung ventilation in patient with tracheostomy--a case report.
One-lung ventilation (OLV) with a double-lumen endotracheal tube or Univent may be achieved difficulty in morbidly obese, mouth opening-limited or critically ill patients. Now, a new fiberoptically directed wire-guided endobronchial blocker (WEB) can be applied for these conditions. We report the use of a new endobronchial blocker in a pharyngeal cancer patient after pharyngectomy. ⋯ Then we use the WEB to achieve OLV. The WEB was guided by a loop, and through the appropriate position of left main bronchus by pediatric fiberoptic bronchoscope. Finally, OLV was accomplished smoothly with combination of a non-kinking endotracheal tube and a WEB.
