Observational Study
Effect of laryngotracheal topical anesthesia on recurrent laryngeal nerve monitoring during thyroid Surgery.
Intraoperative neuromonitoring of the recurrent laryngeal nerve (RLN) is often used as an adjunct for RLN identification and preservation during thyroidectomies. Laryngotracheal anesthesia (LTA) with topical lidocaine reduces coughing upon emergence from anesthesia and in the immediate postoperative period; however, its use is prohibited with concerns that it could decrease the sensitivity of the intraoperative neuromonitoring. We hypothesize that there is no difference in measurements of nerve conduction made before and after LTA administration. ⋯ Laryngotracheal anesthesia had no significant effect on RLN nerve conduction in the period assessed.

Over the last 6 years, our center has introduced a novel technique combining peripheral nerve blocks (femoral and lateral femoral cutaneous nerves) with sedation using propofol with alfentanil target-controlled infusion for hip fracture surgery. The purpose of this review was to identify if adverse outcomes (of mortality and length of stay) were associated with its introduction compared to spinal or general anesthesia. ⋯ This novel technique does not appear to be associated with adverse mortality or length of stay after hip fracture surgery.

Randomized Controlled Trial Comparative Study
Evaluation of double-lumen endotracheal tube extubation force by extraction angle: a prospective randomized clinical trial.
Gentle and noninvasive double-lumen tracheal tube (DLT) extubation is important for both airway and circulatory management, especially after lung resection. We performed a prospective randomized clinical trial comparing DLT extubation force based on 2 different extraction angles. ⋯ Our findings suggest that DLT extubation at 60° requires less force than at 90° and was accompanied by a smaller increase in blood pressure. Thus, extraction at 60° may be less invasive and beneficial for patients undergoing DLT extubation.
