Compared with traditional open surgery, the laparoscopic techniques have been developed to significantly reduce postoperative pain and accelerate postoperative recovery; however, most donors still experience more than moderate pain after surgery. Ensuring maximum perioperative safety and postoperative pain control for donors remains a top priority for LDN. Our group reported a novel blockade technique that allows local anesthetic to be injected directly to reach the low thoracic paravertebral space under direct laparoscopic observation via the arcuate ligament to achieve somatic and visceral pain analgesia; this technique has been successfully applied to patients undergoing retroperitoneal laparoscopic nephrectomy.
