Better With Ultrasound: Paracentesis. Paracentesis is a commonly performed procedure and generally considered to be low risk. Despite its overall favorable safety profile, use of ultrasound has been demonstrated to reduce the incidence of complications, especially in higher risk patients. Many individual ultrasound techniques have been described in the literature, each with the goal of making paracentesis safer. This article presents a systematic approach for incorporating many of these tools into bedside practice and includes a series of illustrative figures and narrated video presentations to demonstrate the techniques described.
