Intrathecal Morphine for Thoracoscopic Surgery

Comparison of the Effects of Intrathecal Morphine at Two Different Doses in Thoracoscopic Lung Resection

Thoracic surgery is one of the surgeries where postoperative pain is intense. In this study, the investigators aimed to compare the efficacy of two different intrathecal morphine doses administered for postoperative analgesia according to patients' ideal body weight.

Patients who underwent video-assisted thoracic surgery were divided into two groups: 10 mcg/kg and 7 mcg/kg intrathecal morphine for postoperative analgesia. Intraoperative and postoperative hemodynamic variables, postoperative morphine consumption, postoperative pain scores, side effects and additional analgesic requiretment were recorded.
