Be that as it may, arterial tourniquet has numerous injurious impacts including hemodynamic changes and tourniquet-induced pain which sometimes can be severe and intolerable. Objectives: Our primary aim was to assess the impact of performing “Lumbar Plexus Block and sciatic nerve block” with General Anesthesia (GA) on the degree of arterial tourniquet-induced hemodynamic effects. On the other hand, our secondary aims were: amount of postoperative analgesic prerequisites, patient satisfactory score and documented side effects. Settings and Design: Ain Shams University, Orthopedic operating theatre;a prospective, randomized, double-blind study. Methods and Material: The physical status of 50 patients (both sexes) including I and II patients from American Society of Anesthesiologists, whose ages are from 20 - 40 years, is not so ideal when they are undergoing elective knee Arthroscopy. The duration lasts no more than ninety minutes under GA with application of tourniquet. Patients were allotted haphazardly to one of two groups. In Group C (Control group): Only GA. In Group B: LPB and sciatic nerve block were performed just before GA administration. Intraoperative hemodynamics was recorded at specific timings. Results: Incidence of tourniquet induced hypertension (TIH) was markedly less with Group B at: forty five, sixty, seventy five mins after tourniquet inflation and just before tourniquet deflation. Also, the total ketorolac consumption during first 24 hours of postoperative period was significantly less with Group B (p Conclusions: Combined Sciatic-Lumbar plexus blocks when combined with general anesthesia were very effective in attenuating TIH.展开更多
目的:探讨超声引导下腰骶丛神经阻滞联合全麻对行髋关节置换术老年病人术后谵妄(POD)的影响。方法:选取髋关节置换术老年病人80例,随机分为腰骶丛神经阻滞联合全麻组(h组)和全麻组(q组),各40例。2组病人均采用喉罩通气,维持脑电双频指数...目的:探讨超声引导下腰骶丛神经阻滞联合全麻对行髋关节置换术老年病人术后谵妄(POD)的影响。方法:选取髋关节置换术老年病人80例,随机分为腰骶丛神经阻滞联合全麻组(h组)和全麻组(q组),各40例。2组病人均采用喉罩通气,维持脑电双频指数40~60,术后静脉自控镇痛(PCA)。比较2组病人术中麻醉药物用量、手术相关指标;采用视觉模拟量表(VAS)评估病人术后疼痛情况;于术前(D0)、术后第1(D1)、3(D3)、7(D7)天分别测定病人意识模糊评估量表(CAM)评分,并抽取静脉血检测白细胞介素(IL)-1β、IL-6、肿瘤坏死因子α(TNF-α)、C反应蛋白(CRP)和S100β蛋白水平。结果:与q组相比,h组病人术中麻醉药物用量、术后拔管时间、术后24 h PCA次数、术后各时间点VAS评分、首次下床时间及出院时间均明显减少(P<0.01);h组术后IL-1β、IL-6、TNF-α、CRP、S100β蛋白水平、CAM评分及POD发生率均明显低于q组(P<0.01)。结论:超声引导下腰骶丛神经阻滞联合全麻较单纯全麻,可减少行髋关节置换术的老年病人麻醉药用量,完善镇痛,降低炎性反应和POD发生率,有助于病人术后快速康复。展开更多
