Abstract:
Objective:To evaluate the efficacy of subomohyoid anterior suprascapular nerve block (SSNB) in the patients undergoing arthroscopic shoulder surgery with general anesthesia.Methods:Sixty patients of either sex, aged 18-64 yr, with body mass index of 18-30 kg/m 2, of American Society of Anesthesiologists physical status Ⅰor Ⅱ, scheduled for elective arthroscopic shoulder surgery, were divided into 2 groups ( n=30 each) using a random number table method: SSNB group (S group) and interscalene brachial plexus block group (I group). Before induction, 0.375% ropivacaine hydrochloride 15 ml was injected between C 5-C 6 nerve roots in group I and around the anterior suprascapular nerve in group S under ultrasound guidance.Diaphragmatic excursion, occurrence and degree of diaphragmatic paralysis, decrease in SpO 2, dyspnea, Horner syndrome and sensory block in the C 5-T 1 dermatomes were assessed at 30 min after injection.The intraoperative consumption of remifentanil, extubation time, and length of post-anesthesia care unit stay were recorded.Quality of Recovery-15 score for patient′s satisfaction with analgesia, effective pressing frequency of analgesic pump, requirement for rescue analgesia, nausea and vomiting and nerve block-related complications within 24 h after surgery were recorded. Results:Compared with group I, the incidence of diaphragmatic paralysis was significantly decreased, the degree of diaphragmatic paralysis was reduced, diaphragmatic excursion was increased, the amplitude of decrease in SpO 2 was reduced, the incidence of dyspnea and Horner syndrome was decreased, extubation time was shortened ( P<0.05), and no significant change was found in the incidence of sensory block in the C 5-T 1 dermatomes, intraoperative consumption of remifentanil, effective pressing frequency of analgesic pump, requirement for rescue analgesia, score for patient′s satisfaction with analgesia, incidence of nausea and vomiting, length of post-anesthesia care unit stay, or Quality of Recovery-15 score in group S ( P>0.05). Conclusions:The subomohyoid anterior SSNB not only provides reliable perioperative analgesia, but also reduces the risk of diaphragmatic paralysis when used in the patients undergoing arthroscopic shoulder surgery with general anesthesia.
