Intra-operative effect of interscalene brachial plexus block to arthroscopic rotator cuff repair surgery

To determine whether the placement of an interscalene brachial plexus block (IBPB) with general anaesthesia before shoulder arthroscopy would be effective in establishing a clear visual field and in shortening the surgical procedure.
This prospective randomized control trial study included 152 patients who had undergone arthroscopic rotator cuff repair. Group A received IBPB and group B did not receive IBPB. A visual clarity scale (VCS) was determined by arthroscopic visualization. The systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), duration of surgical procedure, VCS, and medication that was administered for haemodynamic stability were recorded. Results: The VCS was improved in group A at stages 2 and 3 of the surgical procedures (p < 0.05), but there were no significant difference at stages 1 (p = 0.288) and 4 (p = 0.062). SBP, DBP, and HR were higher in group B during surgery (p < 0.05). The administered analgesics were higher in group B (p = 0.003), but there were no differences in hypotensive agents (p = 0.287). No significant difference was observed for the duration of surgery (p = 0.704).
Pre-operative IBPB with general anaesthesia for arthroscopic rotator cuff repair was beneficial in maintaining haemodynamic stability and improving the VCS during surgery.
