Randomized Controlled Trial Comparative Study
Addition of lidocaine to levobupivacaine reduces intrathecal block duration: randomized controlled trial.
The duration of the spinal block is a concern for anesthetists. Low dose intrathecal lidocaine has vasodilatory effects and increases the local anesthetic clearance from the intrathecal space. The aim was to investigate whether this effect of lidocaine can be used to increase the resolution of levobupivacaine spinal anesthesia. ⋯ Addition of low dose lidocaine to hyperbaric levobupivacaine reduces the duration of the intrathecal block provided by hyperbaric levobupivacaine. This technique can be used to reduce the spinal block duration for relatively short procedures like TUR-P.

Randomized Controlled Trial Comparative Study
Randomized, controlled trial comparing the effects of anesthesia with propofol, isoflurane, desflurane and sevoflurane on pain after laparoscopic cholecystectomy.
Pain is the primary complaint and the main reason for prolonged recovery after laparoscopic cholecystectomy. The authors hypothesized that patients undergoing laparoscopic cholecystectomy will have less pain four hours after surgery when receiving maintenance of anesthesia with propofol when compared to isoflurane, desflurane, or sevoflurane. ⋯ Patients receiving maintenance of general anesthesia with propofol do not have less pain after laparoscopic cholecystectomy when compared to isoflurane, desflurane, or sevoflurane.

Randomized Controlled Trial Comparative Study
Comparison of the effects and complications of unilateral spinal anesthesia versus standard spinal anesthesia in lower-limb orthopedic surgery.
A restricted sympathetic block during spinal anesthesia may minimize hemodynamic changes. This prospective randomized study compared unilateral and bilateral spinal anesthesia with respect to the intra- and postoperative advantages and complications of each technique. ⋯ When unilateral spinal anesthesia was performed using a low-dose, low-volume and low-flow injection technique, it provides adequate sensory-motor block and helps to achieve stable hemodynamic parameters during orthopedic surgery on a lower limb. Patients were more satisfied with this technique as opposed to the conventional approach. Furthermore, this technique avoids unnecessary paralysis on the non-operated side.

Randomized Controlled Trial
Ondansetron reducing pain on injection of etomidate: a controlled randomized study.
Etomidate causes pain when injected intravenously. In this study we sought to determine if pretreatment by ondansetron reduces the pain on injection of etomidate. ⋯ This study illustrates that pre-treatment with intravenous ondansetron significantly reduces the pain on injection of etomidate.

Randomized Controlled Trial
Oxygen concentrators performance with nitrous oxide at 50:50 volume.
Few investigations have addressed the safety of oxygen from concentrators for use in anesthesia in association with nitrous oxide. This study evaluated the percent of oxygen from a concentrator in association with nitrous oxide in a semi-closed rebreathing circuit. ⋯ The FiO2 in the mixture of O293 and nitrous oxide fell during the observation period although oxygen saturation was higher than 98.5% throughout the study. Concentrators can be considered a stable source of oxygen for use during short anesthetic procedures, either pure or in association with nitrous oxide at 50:50 volume.
