Massive Air Embolism during off-pump CABG: A Case Report

Off-pump coronary artery bypass grafting (OPCAB), although devoid of the morbidity associated with cardiopulmonary bypass (CPB), has its own technical difficulties. Achieving optimum tissue stabilization on a beating heart along with hemodynamic fragility due to extreme positioning also complicates the anesthetic management. In addition, it is difficult to obtain a clear surgical field in the presence of arteriotomy. The use of catheter-directed high-flow gas blower (mister blower) helps achieve a clear surgical field to a great extent. However, there have been reported cases of arterial and pulmonary embolism caused by these high-flow gas blowers. The present case reports a case of massive venous air embolism caused by the use of mister blower.
