Paracentesis is a core competency for hospitalists. Using ultrasound for fluid localization is standard practice and involves a low-frequency probe. Experts recommend a 2-probe technique, which incorporates a high-frequency ultrasound probe in addition to the low-frequency probe to identify blood vessels within the intended needle path. Evidence is currently lacking to support this 2-probe technique, so we performed a pre- to postintervention study to evaluate its effect on paracentesis-related bleeding complications. From February 2010 to August 2011, procedures were performed using only low-frequency probes (preintervention group), while the 2-probe technique was used from September 2011 to February 2016 (postintervention group). A total of 5777 procedures were performed. Paracentesis-related minor bleeding was similar between groups. Major bleeding was lower in the postintervention group (3 [0.3%], n = 1000 vs 4 [0.08%], n = 4777; P=.07). This clinically meaningful trend suggests that using the 2-probe technique might prevent paracentesis-related major bleeding. (C) 2018 Society of Hospital Medicine
