Randomized Controlled Trial Comparative Study
Intrathecal hyperbaric 2% prilocaine versus 0.4% plain ropivacaine for same-day arthroscopic knee surgery: a prospective randomized double-blind controlled study.
Short-duration spinal anesthesia is a good option for ambulatory knee surgery. Hyperbaric 2% prilocaine has short onset and rapid recovery times and, therefore, may be well suited in this setting. The aim of this study was to compare the times to reach motor block, motor block resolution, and discharge from the postanesthesia care unit (PACU) between hyperbaric 2% prilocaine and 0.4% plain ropivacaine. ⋯ The recovery of motor block was faster after intrathecal administration of hyperbaric 2% prilocaine compared with 0.4% plain ropivacaine; however, discharge time was similar between the two groups. Both drugs showed a similar risk profile.

Randomized Controlled Trial Comparative Study
Comparison of the endotracheal tube cuff pressure between a tapered- versus a cylindrical-shaped cuff after changing from the supine to the lateral flank position.
Positional change can displace an endotracheal tube (ETT) and change the ETT cuff pressure in a tracheally intubated patient. Endotracheal tubes with different cuff shapes may lead to different cuff pressures after positional change. We hypothesized that the intracuff pressure in the TaperGuard™ ETT with a tapered-shaped cuff would be higher than that in the conventional ETT with a cylindrical-shaped cuff after a change from the supine to the lateral flank position. ⋯ After the change from the supine to the lateral flank position, the ETT cuff pressure was significantly higher in the TaperGuard ETT than in the conventional ETT, although the extent of cephalad displacement of the ETT was comparable between the two groups. This trial was registered at Clinicaltrials.gov: NCT02165319.

Randomized Controlled Trial Comparative Study
Role of contextualizing a crisis scenario on the performance of a cricothyrotomy procedural task.
Simulation is an important alternative to evaluate cricothyrotomy, a rare life-saving procedure. This crossover study aimed to determine whether contextualization of a crisis scenario would impact the performance of a cricothyrotomy procedural task. ⋯ Contextualization of a crisis scenario did not affect the performance of a cricothyrotomy procedural task on a tissue-mannequin simulator. These findings may have implications when considering the feasibility and cost-effectiveness for assessing the performance of cricothyrotomy procedural tasks.

Randomized Controlled Trial
Effect of prophylactic benzydamine hydrochloride on postoperative sore throat and hoarseness after tracheal intubation using a double-lumen endobronchial tube: a randomized controlled trial.
We evaluated the prophylactic effect of benzydamine hydrochloride (BH) spray on postoperative sore throat and hoarseness secondary to intubation with a double-lumen endobronchial tube (DLT). ⋯ Prophylactic application of BH to the DLT cuff and oropharyngeal cavity reduces the incidence and severity of postoperative sore throat and the incidence of hoarseness associated with DLT intubation. The trial was registered at the Clinical Research Information Service (KCT0001068).
