Cardiac arrest during surgery and ventilation in the prone position: a case report and systematic review

We present a case report of successful resuscitation following cardiac arre st in a patient undergoing surgery in the prone position. A systematic revi ew of the literature identified 22 further cases. Risk factors for intra-op erative cardiac arrest in patients in the prone position include: cardiac a bnormalities in patients undergoing major spinal surgery, hypovolaemia, air embolism, wound irrigation with hydrogen peroxide, poor positioning and oc cluded venous return, Cardiac arrest is also a risk in the increasing numbe r of patients with acute respiratory distress syndrome ventilated in the pr one position. Management of prone cardiac arrest may be improved by identif ication of high-risk patients, careful patient positioning, use of invasive monitoring and placement of self-adhesive defibrillator paddles. Suitable techniques for cardiopulmonary resuscitation including methods for chest co mpression, defibrillation and the management of air embolism are discussed. (C) 2001 Elsevier Science Ireland Ltd.
