轻比重布比卡因应用于老年下肢骨折麻醉中的可行性

Feasibility of light specific gravity of bupivacaine applied in the elderly patients with lower limb fractures anesthesia

目的探讨轻比重布比卡因在老年下肢骨折麻醉中的可行性。方法将我院收治的80例行椎管内麻醉下肢骨折手术的老年患者按照随机数表法将其分为观察组与对照组,各40例。观察组采取轻比重布比卡因麻醉,对照组采取重比重布比卡因麻醉。比较两组患者的感觉阻滞情况、镇痛满意度及不良反应情况。结果两组患者的阻滞起效时间及阻滞平面固定时间比较,差异无统计学意义(P>0.05);观察组患者的阻滞持续时间明显长于对照组(P<0.05)。观察组患者的镇痛满意度明显高于对照组(P<0.05)。两组患者不良反应总发生率比较,差异无统计学意义(P>0.05)。结论轻比重布比卡因在老年下肢骨骨折手术麻醉中具有可行性,麻醉效果满意,起效快,术后恢复快,可作为老年下肢骨骨折手术中的首选麻醉方法。

Objective To explore the feasibility of light specific gravity of bupivacaine applied in the elderly patients with lower limb fractures anesthesia. Methods A total of 80 elderly patients undergoing spinal anesthesia with lower extremity fractures in our hospital were enrolled and divided into observation group and control group according to the random number table method, with 40 cases in each group. The observation group was given light specific gravity of bupivacaine anesthesia, and the control group was given heavy specific gravity of bupivacaine. The sensory block, analgesic satisfaction and adverse reactions were compared between the two groups. Results There were no significant differences in the time of blocking and the time of fixation between the two groups（P〈0.05）. The duration of block in the observation group was significantly longer than that in the control group（P〈0.05）. The analgesic satisfaction in the observation group was significantly higher than that in the control group（P〈0.05）. There was no significant difference in the total incidence of adverse reactions between the two groups（P〈0.05）. Conclusion Light specific gravity of bupivacaine applied in elderly lower limb fractures surgery anesthesia is feasible, the anesthesia effect is satisfactory, with quick onset and rapid postoperative recovery, which can be the preferred method of anesthesia in elderly lower limb fractures surgery.
