Pericardiocentesis for Pericardial Effusion
The ideal position for performing a pericardiocentesis is with the patient in sternal recumbency. The procedure can also be performed with a patient in lateral recumbency or in a standing position, depending on their disposition. Proper restraint is vital to prevent pulmonary laceration or cardiac perforation. The patient should be attached to an electrocardiogram during the procedure to monitor for ventricular premature contractions due to possible unintended cardiac contact. The pericardiocentesis site should be clipped and aseptically prepared with a chlorhexidine‐based antiseptic solution. The instruments needed are listed in Box 2.14 (see also Chapter 34, Figure 34.3 and Chapter 45).
