Randomized Controlled Trial Comparative Study
Faster wash-out and recovery for desflurane vs sevoflurane in morbidly obese patients when no premedication is used.
The aim of this study was to compare desflurane vs sevoflurane kinetics and dynamics in morbidly obese patients and their recovery profile when no premedication had been used. ⋯ Desflurane provides faster wash-in and wash-out than sevoflurane in morbidly obese patients, and recovery is much faster after desflurane administration when no premedication has been used.

Effects of using two airway exchange catheters on laryngeal passage during change from a double-lumen tracheal tube to a single-lumen tracheal tube.
A thin airway exchange catheter (AEC) is often used for changing from a double-lumen tracheal tube (DLT) to a single-lumen tracheal tube. However, passage of the tube into the trachea is often difficult. The purpose of this study was to evaluate the effectiveness of using two AECs for tracheal tube exchange. ⋯ The use of two AECs reduces the incidence of impingement of the tube into the trachea during tracheal tube exchange.

Randomized Controlled Trial
Changes in a surgical stress index in response to standardized pain stimuli during propofol-remifentanil infusion.
The surgical stress index (SSI) is based on a sum of the normalized pulse beat interval (PBI) and the pulse wave amplitude (PPGA) time series of the photoplethysmography. As a measure of the nociception-anti-nociception balance in response to a standardized pain stimulus, SSI was compared with EEG changes in state and response entropy (SE and RE), PPGA, and heart rate (HR) during various targeted pseudo-steady-state concentrations of propofol and remifentanil. ⋯ SSI appeared to be a better measure of nociception-anti-nociception balance than SE, RE, HR, or PPGA.

Randomized Controlled Trial Comparative Study
Comparison of i.v. cannula and Stevens' cannula for sub-Tenon's block.
Sub-Tenon's local anaesthesia (STLA) is growing in popularity for ophthalmic surgery, and is widely regarded as safer than the alternative sharp needle techniques. Although safe, STLA is not devoid of risk. Therefore, the effectiveness of a plastic i.v. cannula was compared with the traditional metal Stevens' cannula for delivering STLA. ⋯ A 20 G Optiva i.v. cannula and the Stevens' sub-Tenon's cannula were equally effective at providing STLA.

Influence of intraoperative opioid on postoperative pain and pulmonary function after laparoscopic gastric banding: remifentanil TCI vs sufentanil TCI in morbid obesity.
Choice of opioid may influence postoperative pain, recovery, and respiratory homeostasis in morbid obesity. The aim of this study was to compare the effects of target-controlled infusions (TCIs) of remifentanil or sufentanil on postoperative analgesia, recovery, and pulmonary function after laparoscopic gastric banding. ⋯ As few differences occurred in the postoperative period, the theoretical advantage of remifentanil over the longer acting sufentanil can be questioned when using TCI technology.
