Purpose Of ReviewCardiac arrest of patients during anesthesia has been the driving force behind the development of this specialty. Safer procedures, new anesthetics, and technical improvements such as monitoring devices and ventilators have successfully reduced intraoperative mortality. Nevertheless, modern technology itself creates specific risks; and causes, diagnosis, and management of anesthesia-related cardiac arrest differ considerably from situations encountered elsewhere.Recent FindingsCardiac arrest attributable to anesthesia occurs from 0.5 to 1 case per 10,000 interventions. Pediatric cases show a higher incidence (1.4-4.6 per 10,000). However, with the increasing age of patients, preexisting disease or trauma, and new surgical interventions cardiac arrests remain a serious concern. Environmental considerations are gradually becoming more important than mere technological improvements, and educational inputs try to create safer surroundings by recognizing human factors such as efficient communication, awareness, error culture, crew resources utilization, and preparedness for more effective crisis management.SummaryThe anesthetic environment has become much safer than it was 50 years ago. For a successful management of cardiac arrest during operative procedures, not only individual knowledge and skills but also institutional safety culture have to be implemented into education, training, and everyday practice of this specialty.
