Randomized Controlled Trial
Omitting fentanyl reduces nausea and vomiting, without increasing pain, after sevoflurane for day surgery.
Despite advantages of induction and maintenance of anaesthesia with sevoflurane, postoperative nausea and vomiting occurs frequently. Fentanyl is a commonly used supplement that may contribute to this, although it may also improve analgesia. ⋯ As fentanyl exacerbated postoperative nausea and vomiting without an improvement in postoperative pain and also had adverse cardiorespiratory effects, it appears to be an unnecessary and possibly detrimental supplement to sevoflurane in day surgery.

Failed intubation is an important cause of anaesthetic-related maternal mortality. The purpose of this study was to determine the ability to predict difficult visualization of the larynx from the following preoperative airway predictive indices, in isolation and combination: modified Mallampati test, the ratio of height to thyromental distance and the Upper-Lip-Bite test. ⋯ The ratio of height to thyromental distance may prove a useful screening test for predicting difficult laryngoscopy in obstetric population.

Randomized Controlled Trial Comparative Study
Individual titration of propofol plasma target improves anaesthetic stability in patients undergoing major abdominal surgery: a comparison with manually controlled infusion.
The impact of anaesthesia using target-controlled infusion with propofol on intraoperative stability, recovery and cost compared to manually controlled infusion has been evaluated with inconsistent results. We studied a new device that allows more individual titration of propofol target-controlled infusion by using the effect-site concentration at the loss of eyelash reflex to predict the maintenance infusion rate (FM-TCI). ⋯ FM-TCI helps to provide more stable anaesthesia conditions requiring less-frequent adjustments of the propofol infusion compared to manually controlled infusion in patients undergoing major abdominal surgery.
