目的:评价肩胛舌骨肌下前路肩胛上神经阻滞(SSNB)用于全麻肩关节镜手术患者的效果。方法:择期行肩关节镜手术患者60例，性别不限，年龄18~64岁，ASA分级Ⅰ或Ⅱ级，BMI 18~30 kg/mn 2，采用随机数字表法分为2组(n n＝30)：SSNB组(S组)和肌间沟臂丛神经阻滞(ISB)组(I组)。麻醉诱导前，I组在Cn 5-6神经根之间、S组在肩胛舌骨肌下的前路肩胛上神经周围分别注射0.375%盐酸罗哌卡因15 ml。注药后30 min，记录膈肌活动度，膈肌麻痹发生情况和程度、SpOn 2降低幅度、呼吸困难和Horner征发生情况，Cn 5-Tn 1皮区感觉阻滞情况。记录术中瑞芬太尼用量。记录气管拔管时间、PACU停留时间。记录术后24 h 15项恢复质量量表(QoR-15)评分、镇痛满意度评分、镇痛泵有效按压次数、补救镇痛情况、恶心、呕吐及神经阻滞相关并发症发生情况。n 结果:与I组比较，S组膈肌麻痹发生率降低，程度减轻，膈肌活动度升高，SpOn 2降低幅度减小，Horner征和呼吸困难发生率明显降低，气管拔管时间缩短(n P0.05)。n 结论:肩胛舌骨肌下前路SSNB用于全麻肩关节镜手术患者不仅围术期镇痛效果确切，还可降低膈神经麻痹发生风险。“,”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/mn 2, of American Society of Anesthesiologists physical status Ⅰor Ⅱ, scheduled for elective arthroscopic shoulder surgery, were divided into 2 groups (n 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 Cn 5-Cn 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 SpOn 2, dyspnea, Horner syndrome and sensory block in the Cn 5-Tn 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.n 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 SpOn 2 was reduced, the incidence of dyspnea and Horner syndrome was decreased, extubation time was shortened (n P0.05).n 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.
