Unusual case of intraoperative acute cor pulmonale during spine surgery.

Perioperative complications of prolonged surgery and prone positioning are well known. Changing the position from prone to supine in an anesthetized patient can result in aspiration and airway obstruction. The drop-in oxygen saturation and hemodynamic changes are warning signs and can cause acute cardiac decompensation leading to diagnostic dilemma. We present a case where the patient had these changes after changing the position after spine surgery in prone position. A quick response from the treating anesthesiologist and active involvement of cardiologist helped in reaching the diagnosis and successful management of aspiration pneumonitis in this patient. We conclude that a quick response in investigations and multimodality approach helps in the management of such perioperative complications.
