WebResults: All animals experienced pulmonary hypertension, depressed stroke volume, hypoxemia, hypercarbia, and acidemia during intravenous CO2 infusion. They had systemic hypertension at the low rate of hypotension at the highest rate of infusion. End-tidal CO2 levels briefly decreased, then increased in all cases. WebCO2 embolism may occour during retroperitoneoscopic adrenalectomy, and an acute decrease in arterial blood pressure should alert both the urologists and anesthesiologists to this rare and fatal complication.
