Ultrasound-Guided Stellate Ganglion Block With Preserved Motor Function for Upper Extremity Surgery.

ABSTRACT

While stellate ganglion blockade (SGB) is commonly used in the treatment and management of patients who suffer from chronic pain, we are reporting a case where an ultrasound-guided SGB was used for management of acute perioperative pain for a patient undergoing upper extremity surgery. The patient was classified as the American Society of Anesthesiologists (ASA) class 1, without any significant past medical history, including no history of chronic pain, opioid use, or peripheral neuropathy. The patient was scheduled for tendon repair of the hand following trauma with subsequent lacerations. While general anesthesia, a brachial plexus blockade, or combination of the two are generally used in current practice for upper extremity surgery, these typically do not allow for intraoperative evaluation of motor function. In our case, an ultrasound-guided SGB was used to provide analgesia while still allowing for intraoperative assessment of motor function during the critical components of the repair. This case illustrates the potential advantages of an ultrasound-guided SGB for decreasing acute postoperative pain scores, decreasing overall postoperative pain medication use, as well as maintaining intraoperative motor function in cases where such monitoring may be advantageous and allow for optimal surgical repair.
