Pericardiocentesis T2 Emergency Medicine Procedures, 2e YR 2013 FD 2013 PB The McGraw-Hill Companies PP New York, NY SN 978-0-07-161352-1 LK accessemergencymedicine.mhmedical.com/content.aspx?aid=57703684 RD 2024/04/25 AB Pericardiocentesis is the removal of fluid from the pericardial space surrounding the heart. The fluid is usually aspirated with a needle and syringe. Occasionally, a catheter is placed within the pericardium or a surgical approach is used. This may be performed for diagnosis, to obtain pericardial fluid; to relieve a pericardial effusion and improve cardiac output; or as a lifesaving measure to relieve a cardiac tamponade. The technique is relatively simple to perform yet has a significant rate of complications.
