The addition of interscalene block to general anesthesia for patients undergoing open shoulder procedures.
Several studies have demonstrated that interscalene brachial plexus anesthesia alone decreases postoperative pain, nausea, vomiting, urinary retention, and unplanned hospital admissions compared with general anesthesia alone. Anecdotal evidence suggests that an interscalene block combined with general anesthesia decreases unwanted effects of general anesthesia following open shoulder surgery. We compared the effect of combined interscalene block and general anesthesia with general anesthesia alone on Aldrete scores, length of postanesthesia care unit (PACU) stay, verbal rating scale (VRS) pain scores, incidence of postoperative narcotic administration and nausea, and patient satisfaction in a convenience sample of 52 men and women, ASA physical status I, II, or III. Group 1 received standard general anesthesia alone. Group 2 received an interscalene block in combination with general anesthesia using a standard technique. Group 2 had significantly lower VRS scores than group 1 while in the PACU, on the day of surgery, and on postoperative days 1 and 2. Overall satisfaction with the anesthetic technique was higher in the group 2 than in group 1. Results suggest that adding an interscalene block to general anesthesia can be of value in today's outpatient-dominated surgery schedule.
