    AimThe aim of this study was to assess the influence of interscalene brachial plexus blocks on the functional outcome, subjective pain appraisal and patient satisfaction after open shoulder surgery. These results were compared with patients treated by conventional analgesic measures.Method23 patients with interscalene brachial plexus block (ISB) and 21 patients without ISB were evaluated preoperatively as well as 1, 7, 12 and 90 days after open surgery of the shoulder. By means of a visual analogue scale (VAS) subjective postoperative pain intensity was assessed. Using the Constant score preoperatively and 6 months after surgery the functional status of the treated shoulder was evaluated. At discharge from hospital patients were asked whether they were satisfied with the analgesic measures taken.ResultsThe range of motion of the shoulder of patients treated with an ISB was significantly higher 1 and 7 days after surgery than those without ISB. 12 and 90 days postoperatively the range of motion in the ISB group was still higher, but no longer statistically significant. Assessment of the postoperative subjective pain status showed that patients with an ISB had significantly lower values and required less additional analgesia. In both groups the Constant score was significantly higher 6 months after surgery, compared to the preoperative condition. Compared to the control group, patients treated with ISB were clearly more satisfied with the postoperative pain management.ConclusionBy implementing ISB sufficient analgesia in the early postoperative period after open shoulder surgery is attained, allowing for early physiotherapy. This positively influences convalescence and the outcome of the surgical procedure. Furthermore, patients are visibly more satisfied with the postoperative pain management.
