Randomized Controlled Trial Comparative StudyDetermining the Learning Curve for Acquiring Core Sonographic Skills for Ultrasound-Guided Axillary Brachial Plexus Block.
The objectives of this study were to determine the learning curve for capturing sonograms and identifying anatomical structures relevant to ultrasound-guided axillary brachial plexus block and to determine if massed was superior to distributed practice for this core sonographic skill. ⋯ The proficiency of participants in capturing sonograms and identifying anatomical structures improved significantly over 8 to 10 learning sessions. Because of sample size issues, we cannot make a firm conclusion regarding massed versus distributed practice for this core sonographic skill.

The Use of Epinephrine in Caudal Anesthesia Increases Stroke Volume and Cardiac Output in Children.
Caudal anesthesia is a common and effective regional anesthesia technique in pediatric patients. The addition of epinephrine to local anesthetics in caudal anesthesia is a frequent practice; however, changes in hemodynamic and cardiac parameters produced by epinephrine in caudal anesthesia are not well studied. Using data collected with the ICON noninvasive cardiac output monitor, we examined the hemodynamic changes associated with the administration of epinephrine containing local anesthetics during caudal anesthesia in children. ⋯ Epinephrine added to local anesthetic injected for caudal anesthesia produces significant increases in SV, CO, and CI in children. Stroke volume and CI changes from epinephrine added to local anesthetic for caudal anesthesia seem to take place only in children 6 months or older.

Randomized Controlled TrialQuadratus Lumborum Block Versus Transversus Abdominis Plane Block for Postoperative Pain After Cesarean Delivery: A Randomized Controlled Trial.
The quadratus lumborum block (QLB) may be more effective than transversus abdominos plane (TAP) block for cesarean section analgesia.

Case ReportsLocal Anesthetic-Induced Myotoxicity After Continuous Adductor Canal Block.
Local anesthetic-induced myotoxicity occurs consistently in animal models, yet is reported rarely in humans. Herein, we describe 3 sentinel cases of local anesthetic myotoxicity after continuous adductor canal block (ACB). ⋯ Clinically apparent local anesthetic-induced myotoxicity has been documented rarely in humans undergoing non-ophthalmic surgery. We report 3 sentinel cases associated with continuous ACB.
