ABSTRACT
Cardiac arrest during upper abdominal surgery such as liver transplantation is a rare but very severe complication. Traditional external cardiac compression has been the mainstay of basic life support in general circumstances. Subdiaphragmatic cardiac compression (SDCC), with no incision in the diaphragm, may be a more effective measure. This maneuver can provide more effective and timely cardiac compression via the already open abdomen in surgery and not add extra trauma. This method can provide a quicker and more effective means of circulation support for intraoperative cardiac arrest patients without adding new injuries. Five cases are reported and all the patients had return of spontaneous circulation (ROSC). This is the first report of the SDCC method.
