Postoperative respiratory function is superior after laparoscopic approach compared with open procedures.
In patients with significant respiratory dysfunction and restricted CO2 clearance, impaired postoperative ventilation from residual anesthetics and neuromuscular blockade in the immediate postoperative period may delay removal of absorbed CO2 and may cause significant hypercapnia.
Increased IAP and reverse Trendelenburg position may cause venous stasis that could increase the potential for deep vein thrombosis and pulmonary embolism. (Graduated elastic compression stockings are indicated in the perioperative period.)
