Randomized Controlled Trial
Teaching sonoanatomy to anesthesia faculty and residents: utility of hands-on gel phantom and instructional video training models.
Thousands of patients worldwide annually receive neuraxial anesthesia and analgesia. Obesity, pregnancy, and abnormal spinal anatomy pose challenges for accurate landmark palpation. Further, spinal sonoanatomy is not uniformly taught in residency education, even though its use has previously been shown to improve identification of relevant structures and decrease procedural complications and failure rates. The aim of this study was to evaluate the use of hands-on gel phantom and instructional video training for teaching spinal sonoanatomy among anesthesiology faculty and residents. ⋯ Use of hands-on gel phantom or instructional video training can improve anesthesia staff and resident knowledge of lumbar spine sonoanatomy.

Randomized Controlled Trial
Is there a dose response of dexamethasone as adjuvant for supraclavicular brachial plexus nerve block? A prospective randomized double-blinded clinical study.
The study objective is to examine the analgesic effect of 3 doses of dexamethasone in combination with low concentration local anesthetics to determine the lowest effective dose of dexamethasone for use as an adjuvant in supraclavicular brachial plexus nerve block. ⋯ Low-dose dexamethasone (1-2 mg) prolongs analgesia duration and motor blockade to the similar extent as 4-mg dexamethasone when added to 0.25% bupivacaine for supraclavicular brachial plexus nerve block.

Randomized Controlled Trial Comparative Study
A randomized, single-blinded, prospective study that compares complications between cuffed and uncuffed nasal endotracheal tubes of different sizes and brands in pediatric patients.
To compare any association between the problematic distal placement of cuffed and uncuffed nasal endotracheal tubes (NETTs) of different sizes and brands in pediatric patients. ⋯ The chances of possible complications were significantly higher with cuffed NETT. The NETT should be kept at least 0.5 cm above carina to avoid possible complications.

Randomized Controlled Trial
Effect of acute arterial hypertension on morphine requirements and postsurgical pain.
The study objective was to establish the impact of acute hypertension on morphine's requirements after laparoscopic cholecystectomy. ⋯ The intraoperative acute generation of mild hypertension with phenylephrine reduced postoperative morphine consumption and pain scores after laparoscopic cholecystectomy.
