Asystolic Cardiac Arrest Associated With Unstable Bradycardia During Augmentation Mammaplasty: A Case Report

Cardiac arrest is a rare but reported complication during breast augmentation surgery. It is even more rare in a reportedly healthy patient without preexisting cardiac disease. The authors present the case of a healthy 34-year-old female who underwent elective bilateral augmentation mammaplasty and experienced unanticipated asystolic cardiac arrest intraoperatively following general anesthesia supplemented by a regional pectoral (pec I) nerve block. The performing plastic surgeon provided cardiopulmonary resuscitation while the anesthesiologist initiated a rescue protocol per Advanced Cardiac Life Support (ACLS) guidelines. Fortunately, the patient was resuscitated in a timely manner and had a successful return of spontaneous circulation within 1 minute. This case report serves to briefly review the literature and recommendations on proper resuscitation of cardiac arrest per ACLS protocols as well as discuss unstable bradycardia in otherwise healthy patients undergoing breast augmentation surgery. Plastic surgeons and anesthesiologists who perform this procedure should be aware of the possible, rare but serious progression to asystole as well as the proper resuscitative measures to take should they be required.
