To investigate the distribution pattern of sonographically guided iliopsoas (IP) injections in an unembalmed cadaveric model. ⋯ Sonographically guided IP injections using an in-plane, lateral-to-medial technique place injectate into the IP bursa between the IP tendon and the acetabular rim. Within the limits of this cadaveric investigation, this sonographically guided 7-mL IP "bursa" injection may provide a minimum of 50% circumferential IP tendon coverage and approximately 5 cm of cephalad and caudad flow. There does not appear to be a peritendinous space deep to the IP tendon at the acetabular rim that is both outside the bursa and amenable to sonographically guided injection. Injections into the superficial aspect of the IP using 7-mL volumes may not deliver injectate deep to the IP tendon and therefore may represent a fundamentally different injection.

Hospital-wide survey of bacterial contamination of point-of-care ultrasound probes and coupling gel.
The purpose of this study was to determine the hospital-wide incidence of bacterial contamination of point-of-care (bedside) ultrasound probes and coupling gel at a single academic medical center to predict the risk of nosocomial spread of infection. ⋯ Bacterial contamination of point-of-care ultrasound probes and coupling gel is low at this single academic medical center and involves nonpathogenic organisms only.
