A comparison of interscalene block anaesthesia and general anaesthesia in patients with proximal humerus fracture

Background and purpose: A proximal humerus fracture is a common injury of the shoulder. The aim of this study is to compare the effects of two anaesthetic methods in patients with proximal humerus fracture in development of postoperative pain. Materials and Methods: 50 patients were included in this prospective, randomized study. They were randomized into two groups, ISBA group and GA group. Patients in ISBA group were anesthetized using interscalene block technique ; whilst patients in GA group were anesthetized according to general anaesthesia protocol. The VAS score was assessed every two hours at rest and in motion. We measured time necessary to prepare anaesthesia in both groups, duration of operation, hemodynamic and respiratory stability, loss of blood during operation, price of anaesthesia, use of analgesics postoperatively and patient satisfaction. Results: There was no statistically significant difference between groups regarding demographic characteristics and ASA status. ISBA group had statistically lower VAS score as well as lower analgesics use (P<0.05). There were no statistically significant differences in intraoperative complications, although more hypotension was recorded in GA group. The loss of blood was higher in ISBA group, but this result bears no statistical significance. The time necessary to perform anaesthesia was significantly longer in ISBA group (P<0.05). There is a statistically significant difference regarding patient satisfaction and price, to the advantage of ISBA (P<0.05). Conclusion: ISBA is a better method of anaesthesia than GA in patients with proximal humerus fracture, it leads to better pain relief, lesser use of analgesics, without significant complications.
