BACKGROUNDTo evaluate general anesthesia with sevoflurane vs spinal anesthesia with low dose lidocaine 5% on hemodynamics changes in patients undergoing hip fracture surgery.METHODSIn this randomized double blind trial 100 patients (50 patients in each group) older than 60 years under hip surgery were randomized in general anesthesia with sevoflurane and spinal anesthesia with lidocaine 5%. Hemodynamic changes including mean arterial pressure (MAP) and heart rate, blood loss, pain severity, nausea and vomiting and opioids consumption were compared in two groups.RESULTSDuring surgery, difference between two groups regarding changes in mean arterial pressure was not significant, but the changes in heart rate were significantly different. Mean arterial pressure changes during recovery between two groups were significantly different. But there was no significant difference in heart rate changes. Bleeding in the sevoflurane group was significantly more than spinal group (513.ml vs. 365 ml). Moreover, AS Score, opioid consumption, and the nausea and vomiting in spinal anesthesia group was significantly lower than the sevoflurane group.CONCLUSIONWe showed that general anesthesia with sevoflurane and spinal anesthesia with low dose lidocaine 5% have comparable effects on hemodynamics changes in patients undergoing hip fracture surgery. However postoperative pain score, vomiting and morphine consumption in patients with spinal anesthesia were lower than general anesthesia.

Is Spinal Anesthesia with Low Dose Lidocaine Better than Sevoflorane Anesthesia in Patients Undergoing Hip Fracture Surgery.
