Interscalene block for elective shoulder surgery.

摘要

This study assessed patient experiences with interscalene block anesthesia for elective shoulder surgery. Routine use of interscalene anesthesia was introduced at our institution in 1997. All patients who underwent interscalene anesthesia during the first 3 years of our experience with this regional anesthetic technique were asked to respond to an anesthesia-related questionnaire. Overall patient satisfaction with interscalene anesthesia was 87%, and success rate in achieving a complete motor and sensory block was 79%. The duration of pain relief postoperatively was 10.5 hours for patients with a successful block. Patients consistently reported that having an interscalene block was less painful than anticipated; 90% said they would have interscalene anesthesia again for shoulder surgery. This study demonstrates that interscalene anesthesia for elective shoulder surgery is safe and well accepted in this patient population.
