Comparison of the Analgesic Duration of 0.5% Bupivacaine With 1:200,000 Epinephrine Versus 0.5% Ropivacaine Versus 1% Ropivacaine for Low-Volume Ultrasound-Guided Interscalene Brachial Plexus Block

AUTHORS: Safa, Ben MD et al Anesthesia & Analgesia: April 2021 – Volume 132 – Issue 4 – p 1129-1137 BACKGROUND:  Bupivacaine and ropivacaine are the preferred long-acting local anesthetics for peripheral nerve blocks as they provide prolonged analgesia in the postoperative period. No studies have directly compared the analgesic duration of these commonly used local […]

Hemodynamic and Intestinal Microcirculatory Changes in a Phenylephrine Corrected Porcine Model of Hemorrhage.

AUTHORS: Davies, Simon J. MD et al Anesthesia & Analgesia: March 2021 BACKGROUND: Intraoperative hypotension is a common event, and a recent study suggests that maintenance of blood pressure may reduce complications. The splanchnic circulation provides a reservoir of blood that can be mobilized during hemorrhage; hence, intestinal microcirculation is sensitive to volume changes. The […]

Epidural Administration of Ropivacaine Reduces the Amplitude of Transcranial Electrical Motor–Evoked Potentials

AUTHORS: Furutani, Kenta MD, PhD et al Anesthesia & Analgesia: April 2021 – Volume 132 – Issue 4 – p 1092-1100 BACKGROUND:  An epidurally administered local anesthetic acts primarily on the epidural nerve roots and can act directly on the spinal cord through the dural sleeve. We hypothesized that epidurally administered ropivacaine would reduce the amplitude […]

AUTHORS: Riegger, Lori Q. MD et al Anesthesia & Analgesia: April 2021 – Volume 132 – Issue 4 – p 1075-1083 BACKGROUND:  Intraoperative hypoglycemia can result in devastating neurologic injury if not promptly diagnosed and treated. Few studies have defined risk factors for intraoperative hypoglycemia. The authors sought to characterize children with intraoperative hypoglycemia and determine […]
