摘要
目的分析超声引导下神经阻滞联合喉罩全麻在膝关节置换术中的应用效果。方法选取绵阳四〇四医院2019年10月—2021年10月收治的84例行膝关节置换术的患者,按照随机数字表法分为2组,各42例,对照组采用常规麻醉,观察组给予超声引导下神经阻滞联合喉罩全麻,比较2组麻醉效果。结果观察组苏醒时间、拔管时间、恢复室停留时间均短于对照组(P<0.05)。麻醉前(t_(0))时,2组血流动力学指标水平比较差异无统计学意义(P>0.05),麻醉后30 min(t_(1))、麻醉后1 h(t_(2))、手术结束后(t_(3)),观察组血流动力学指标水平较对照组低(P<0.05)。术后6 h、12 h、24 h、48 h观察组的疼痛程度均低于对照组(P<0.05)。2组不良反应发生率比较差异无统计学意义(P>0.05)。结论超声引导下神经阻滞联合喉罩全麻可改善膝关节置换患者机体内血液循环,降低疼痛程度,提高麻醉效果。
Objective To investigate the effect of ultrasound-guided nerve block combined with laryngeal mask general anesthesia in patients with knee arthroplasty.Methods 84 patients who underwent knee arthroplasty in our hospital from October 2019 to October 2021 were randomly divided into two groups,with 42 cases in each group.The control group was given conventional anesthesia,and the observation group was given ultrasound-guided nerve block combined with laryngeal mask general anesthesia.The anesthetic effects of the two groups were compared.Results The recovery time,extubation time,and recovery room stay time in the observation group were lower(P<0.05).At t_(0),the There was no statistical significance in the comparison of hemodynamic indexes between the two groups(P>0.05).At t_(1),t_(2),and t_(3),the hemodynamic indexes in the observation group were lower(P<0.05).The observation group 6 h,12 h,and 24 h after operation,48 h pain degree was lower(P<0.05).There was no significant difference in the incidence of adverse reactions between the two groups(P>0.05).Conclusion Ultrasound guided nerve block combined with laryngeal mask general anesthesia can improve blood circulation,reduce the degree of pain and improve the effect of anesthesia.
