UNASSIGNED: A total of 40 patients undergoing parotid surgery were prospectively randomized into either the SCPB group (n = 20) or the cervical RLB group (n = 20) using 20 ml of 0.25% bupivacaine plus 5 mcg\\mL epinephrine. Both were combined with ATN block using 5 ml of 0.25% bupivacaine plus 5 mcg\\mL epinephrine.
UNASSIGNED: The time to first request for analgesia was longer in the RLB group than the SCPB group. Total intra operative fentanyl consumption and post-operative pethidine consumption in the first 24h were lower in group RLB. All patients (n = 20) in the SCPB group required rescue analgesia using pethidine, while only 40% of patients required pethidine in the RLB group. Visual analog scale was lower in the RLB group from 2 to 24-h post-operatively, but it was associated with hypotension and longer block technique time occurred with RLB than SCPB. There was no significant difference in side effects except for 20% Horner\'s syndrome in the SCPB group.
UNASSIGNED: Cervical RLB is more effective analgesic technique than SCPB, as the cervical RLB showed longer time to first analgesic request, lower intraoperative anesthetic consumption, lower total post-operative pethidine consumption and lower VAS.
UNASSIGNED:将40例接受腮腺手术的患者随机分为SCPB组(n=20)或宫颈RLB组(n=20),使用20ml0.25%布比卡因加5mcg/mL肾上腺素。两者均与使用5ml0.25%布比卡因加5mcg\\mL肾上腺素的ATN阻滞联合。
UNASSIGNED:与SCPB组相比,RLB组首次要求镇痛的时间更长。RLB组术中芬太尼总消耗量和术后24小时哌替啶消耗量较低。SCPB组的所有患者(n=20)需要使用哌替啶进行抢救镇痛,而RLB组只有40%的患者需要哌替啶。术后2至24小时,RLB组的视觉模拟评分较低,但与低血压相关,与SCPB相比,RLB发生的阻滞技术时间更长.在SCPB组中,除20%Horner's综合征外,副作用无明显差异。
UNASSIGNED:宫颈RLB是比SCPB更有效的镇痛技术,由于宫颈RLB显示出第一次镇痛请求的时间较长,降低术中麻醉消耗,术后哌替啶总消耗量较低,VAS较低。
