Common Peroneal Nerve Palsy after Lithotomy Position: Two case reports / 대한마취과학회지

Motor neuropathy of a lower extremity is well recognized potential complication of procedures performed on patients in a lithotomy position. Mechanisms of nerve injury are unclear but the incidence of perioperative nerve injuries can be reduced if anesthetists are aware of their causes and pathophysiolgies. It is important to note that reduced duration in lithotomy position may reduce the risk of lower extremity neuropathies. We experienced two case of common peroneal nerve palsy after lithotomy positioning. Diagnosis was based on history, a clinical examination and electrophysiologic studies. A neurologic examination revealed hypersthesia over the dorsum of the left foot with inability to perform active dorsiflexion. Electrophysiologic studies showed delayed latency and low amplitude of nerve action potential.

The Effect of the Thoracic Epidural Analgesia on Postoperative Pain and Pulmonary Function Recovery after Thoracoscopic Surgery / 대한마취과학회지

BACKGROUND: The study was performed to evaluate the effect of the thoracic epidural analgesia on the postoperative pain and pulmonary function after thoracoscopic surgery. METHODS: Postoperative pain control consisted of continuous thoracic epidural infusion of normal saline in group 1 (Control group) and 0.125% bupivacaine mixed with fentanyl 5microgram/ml in group 2 (TEA group) added in single intercostal nerve block patient in sixty patients who had undergone elective thoracoscopic surgery. The visual analogue scale (VAS), Prince-Henry score (PHS) and pulmonary function (FVC and FEV1) were measured preoperatively and postoperatively at 4, 8, 12, 24, 48 hours. RESULTS: There were significant improvement of the degree of pain in both groups but TEA group was lower than control group during 48 hours except at postoperative 4 hours. Pulmonary function was decreased less and recovered faster in TEA group than control group during 48 hours (P < 0.05). CONCLUSIONS: Thoracic epidural analgesia added in single intercostal nerve block has a benefit on the recovery of the postoperative pulmonary function and also provide superior analgesia after thoracoscopic surgery when compared to single intercostal nerve block alone. The authors recommend thoracic epidural analgesia for patient undergoing thoracoscopic surgery who receive single intercostal nerve block.
