pericardiocentesis
Pronunciation: pair-ih-kar-dee-oh-sen-TEE-sis
Emergency procedure to remove fluid from the pericardial space surrounding the heart.
Full Definition
A critical emergency cardiology procedure involving needle aspiration of fluid, blood, or air from the pericardial sac. Performed when cardiac tamponade threatens hemodynamic stability, this intervention can be life-saving in acute settings. The procedure requires precise anatomical knowledge and is often performed under echocardiographic guidance. Documentation must capture the indication, technique used, volume aspirated, and immediate hemodynamic response to guide further treatment decisions.
Usage
Usage note: Often abbreviated as 'pericardial tap' in informal documentation but formal reports should use the full term.
