Incidental Murmurs and the Elective Noncardiac Surgical Patient: A Case Report.

We present a case of left ventricular outflow tract (LVOT) obstruction detected by limited bedside transthoracic echocardiography (TTE). This involved a young and otherwise healthy patient presenting for elective hand surgery with a previously undetected cardiac murmur. It highlights the utility of bedside TTE as an assessment tool and shows the importance of anesthesiologists as perioperative physicians.

A Randomized Controlled Trial of Ultrasound Versus Nerve Stimulator Guidance for Axillary Brachial Plexus Block.

Background: Ultrasound-guided techniques improve outcomes in regional anesthesia when compared with traditional techniques; however, this assertion has not been studied with novices. The primary objective of this study was to compare sensory and motor block after axillary brachial plexus block when performed by novice trainees allocated to an ultrasound- or nerve-stimulator-guided group. A secondary objective was to compare the rates of skill acquisition between the 2 groups.

Cardioplegia Dose Effect on Immediate Postoperative Alterations in Coronary Artery Flow Velocities After Congenital Cardiac Surgery.

Abnormalities in coronary artery (CA) flow detected by echocardiography are increasingly used to guide clinical decisions in patient management. Increased CA flow has been seen postoperatively in congenital cardiac surgery. This study sought to determine immediate postoperative changes in left anterior descending (LAD) CA flow velocities, and to investigate possible factors associated with these changes.
