不同比重布比卡因腰硬联合麻醉在老年下肢骨科手术中麻醉效果对比分析

目的：对比分析不同比重布比卡因腰硬联合麻醉应用于老年下肢骨科手术的麻醉效果。方法：选取我院行下肢骨科手术的老年患者96例，随机分为A、B、C 3组各32例。A、B和C组分别行重、等和轻比重布比卡因麻醉，比较3组患者的麻醉效果。结果：3组患者达最高阻滞平面时间比较差异无统计学意义（P>0.05）；患者感觉阻滞起效时间依次为A组

Effects of the spinal-epidural anesthesia combined with different speciifc gravity of bupivacaine on the elderly patients with lower limb orthopedic surgery

Objective:To compare the effects of the spinal-epidural anesthesia combined with different speciifc gravity of bupivacaine on the elderly patients with lower limb orthopedic surgery. Methods:Ninety-six elderly patients with lower limb surgery were selected and randomly divided into group A, B and C with 32 cases each. Group A, B and C underwent a heavy, equal and light speciifc gravity of bupivacaine anesthesia, respectively and their anesthetic effects were compared. Results:There was no statistical signiifcance in the time for reaching the highest block plane in three groups (P>0.05). The time for the onset of sensory block was less in group A than group B and C in turn (P<0.05). The time for reaching the highest block plane was signiifcantly less in group A than group B and C (P<0.05) while slightly less in group B than group C (P>0.05). MAP and HR were signiifcantly decreased in group A and B at 5 min after anesthesia (P<0.05) and then lfuctuated in the normal range at 10 min after anesthesia while they were lfuctuated in the normal range in group B and C after anesthesia. There was no signiifcant respiratory depression occurred and SpO2 was lfuctuated in the normal range in three groups. Conclusion:The spinal-epidural anesthesia combined with equal speciifc gravity of bupivacaine possesses satisfactory efifcacy and less effect on hemodynamics and is easily controllable and worthy of clinical further practice.
