The Extraperitoneal Approach and Subcutaneous Emphysema are Associated with Greater Absorption of Carbon Dioxide During Laparoscopic Renal Surgery

Abstract

Carbon dioxide absorption during laparoscopic renal surgery increases with time, and is greatest in patients treated through an extraperitoneal approach and in those with subcutaneous emphysema. Nonetheless, with attentive ventilatory management adverse sequelae of hypercapnia can be avoided.
