Randomized Controlled TrialEffect of intravenous dexamethasone on the duration of postoperative analgesia for popliteal sciatic nerve block: a randomized, double-blind, placebo-controlled study.
Intravenous (IV) dexamethasone prolongs the duration of a peripheral nerve block; however, there is little available information about its optimal effective dose. This study aimed to evaluate the effects of three different doses of IV dexamethasone on the duration of postoperative analgesia to determine the optimal effective dose for a sciatic nerve block. ⋯ This study demonstrated that compared to the controls, only IV dexamethasone 10 mg increased the duration of postoperative analgesia following a sciatic nerve block for foot and ankle surgery without the occurrence of adverse events.

Randomized Controlled TrialEndotracheal intubation in patients undergoing open abdominal surgery in the lateral position: a comparison between intubating video stylet and fiberoptic intubating bronchoscopy.
Some situations compel anesthetists to execute endotracheal intubation in the lateral position. We compared elective endotracheal intubation in the lateral decubitus position using the video stylet (VS) device with the fiberoptic (FO) bronchoscope device in patients undergoing abdominal surgery. ⋯ In laterally positioned patients, elective endotracheal intubation with VS provides less intubation time; however, its use is accompanied by a significant increase in the hemodynamic response after intubation and an increased incidence of sore throat.

Randomized Controlled TrialIntraoperative aerosol box use: does an educational visual aid reduce contamination?
The aerosol box was rapidly developed and disseminated to minimize viral exposure during aerosolizing procedures during the COVID-19 pandemic, yet users may not understand how to use and clean the device. This could potentially lead to increased viral exposure to subsequent patients and practitioners. We evaluated intraoperative contamination and aerosol box decontamination and the impact of a preoperative educational visual aid. ⋯ The use of a visual aid significantly decreased intraoperative contamination and improved box cleaning. Despite these findings, a potentially clinically significant amount of viral exposure may exist. Thorough evaluation of the risks and benefits of the aerosol box should be completed prior to use. If an aerosol box is used, a visual aid should be considered to remind practitioners how to best use and clean the box.

Randomized Controlled TrialPrevention of epidural catheter migration: a comparative evaluation of two tunneling techniques.
Epidural analgesia failure episodes can be reduced by catheter fixation techniques with a lower incidence of catheter migration. In this clinical study, we compared the roles of two epidural catheter tunneling techniques for the prevention of epidural catheter migration. ⋯ Catheter migration was significantly reduced by tunneling without a catheter loop in TG2 as compared to the other two groups. Therefore, we suggest routine use of tunneling without a catheter loop technique in anesthesia practice and look forward to future studies with larger sample sizes.

Randomized Controlled Trial Comparative StudyRandomized, controlled trial comparing respiratory and analgesic effects of interscalene, anterior suprascapular, and posterior suprascapular nerve blocks for arthroscopic shoulder surgery.
Interscalene brachial plexus block (ISB) provides excellent analgesia for arthroscopic shoulder surgeries but is associated with adverse effects including hemidiaphragmatic paresis. We aimed to compare the respiratory effects, forced vital capacity (FVC), and forced expiratory volume in 1 second (FEV1) between suprascapular nerve block (SSB) and ISB. ⋯ Anterior SSB preserves lung function and has a comparable analgesic effect as ISB. Thus, it is recommended for arthroscopic shoulder surgeries, especially in patients who have reduced lung function.
