Background: Conventional approaches to brachial plexus blocks may not cover the suprascapular nerve. Accordingly, after shoulder arthroscopy, sensation from the posterior part of the shoulder is commonly spared. Most previous research involving suprascapular nerve blocks described single-injection techniques. However, with the widespread availability and fairly reasonable cost of disposable infusion pumps, continuous catheter techniques provide a more appealing method of prolonging postoperative analgesia., Case Report: We describe 2 patients who were successfully treated with ultrasound-guided continuous suprascapular nerve catheters. With the patient seated, a high-frequency linear ultrasound probe was used. Both patients experienced excellent pain relief without complications., Conclusion: Continuous suprascapular catheter techniques provide good pain relief and improve postoperative analgesia after shoulder arthroscopy.

Introduction: Continuous peripheral nerve block achieves good pain control. However, uncontrolled pain despite an effective block in the target areas of the nerve can be an early sign of ischemia. We report a case of iatrogenic injury to the axillary artery during shoulder surgery in a patient who had continuous supraclavicular block and demonstrate how vigilant monitoring helped the diagnosis and resulted in timely management of upper limb ischemia., Case Report: A 58-year-old female underwent total revision surgery of her right shoulder under continuous supraclavicular block. Postoperatively, she complained of pain along the medial side of her forearm despite clinical evidence of nerve block. Continuous neurovascular monitoring and timely angiography confirmed axillary artery injury, and subsequent vascular repair saved the patient's limb., Conclusion: Iatrogenic injuries to vessels or nerves sometimes occur during orthopedic surgical procedures. Regional anesthesia can mask and delay the onset of these symptoms. Postoperative monitoring and the ability to differentiate between the effects of local anesthetics and the body's response to ischemia are important for avoiding postoperative complications. This case report aims to improve awareness about the need for vigilant monitoring of the distal pulses after peripheral nerve blocks.
