Emergency physician ultrasound diagnosis of pneumoperitoneum in intraoperative patients with peritoneal insufflation.

Objectives: To determine the accuracy of emergency physicians (EPs) in diagnosing pneumoperitoneum with POCUS, and if the volume of pneumoperitoneum affects accuracy.

Methods: POCUS clips were obtained from patients undergoing intraperitoneal insufflation for an elective laparoscopic procedure. Video clips of the right upper quadrant and epigastric regions were obtained prior to insufflation and then after 500 ml, 1000 ml, and 1500 ml of insufflation.

Point-of-Care Cardiac Ultrasound: Feasibility of Performance by Noncardiologists.

Cardiac ultrasound has been used for decades to assess a wide variety of structural and functional pathology, as well as to monitor response to therapy. It offers the advantages of noninvasive, real-time dynamic functional assessment without the risk of radiation. Cardiologists have traditionally employed this modality and have established robust guidelines on the use of echocardiography.
