At least 49 cardiac arrests occurred in the operating room (at a rate of 1.3 cardiac arrests for every 10,000 surgeries), of which 23 resulted in death (at a rate of 0.6 deaths for every 10,000 surgeries). Twenty-eight cardiac arrests occurred during elective procedures and the remaining were emergencies. Among the causes, hyperkalemia was seen as a likely contributory cause in six patients. PEA (Pulseless electrical activity) was the dominant rhythm and often did not precede other life-threatening arrhythmias. In terms of subspecialty, cardiac surgery witnessed the highest number of cardiac arrests followed by solid organ transplant. Nurse anesthetist\/physician anesthesiologist team-delivered care was associated with intraoperative cardiac arrests, with a rate similar to that of all-physician care teams (21 vs. 28), and the death rates were similar (11 vs. 12). Highest number of cardiac arrests belonged to American Society of Anesthesiologists (ASA) 3 category. All patients who sustained cardiac arrests in ASA 2 category also died. Patients with a BMI &gt;30.0 had the highest number of cardiac arrests, although the number of deaths was low.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>Hyperkalemia is a major factor in intraoperative cardiac arrests.
