低剂量布比卡因腰-硬联合麻醉在老年患者髋关节置换手术中的应用

目的观察低剂量腰-硬联合麻醉在老年患者髋关节置换手术中的应用效果及安全性。方法选取本院2012年4月～2013年4月ASAⅡ～Ⅲ级进行髋关节置换手术的60岁以上老年患者52例,行腰椎第2～3椎间隙穿刺注入布比卡因溶液,并置入硬膜外导管。记录麻醉前基础值,注药后5、10、15、30 min的BP,HR,SpO2,评价麻醉效果对血流动力学的影响。结果麻醉后患者的BP、HR、SpO2与麻醉前相比差异无统计学意义,术后无恶心、呕吐和头痛。结论低剂量腰-硬联合麻醉对血流动力学影响小,安全可靠,可安全用于老年患者髋关节置换手术。

Application of low dose bupivacaine spinal-epidural anesthesia in elderly patients with hip replacement

Objective To observe application effect and security of low dose bupivacaine spinal-epidural anesthesia in elderly patients with hip replacement. Methods 52 elderly patients（above 60 years）with hip replacement in ASAⅡ-Ⅲfrom April 2012 to April 2013 were selected.Bupivacaine solution were injected in 2 to 3 gap lumbar of patients and the epidural catheter was placed.BP,HR,SpO2 at preceding anesthesia and after anesthesia of 5,10,15,30 min were recorded,and the influence of anesthesia on hemodynamics was evaluated. Results After anesthesia,BP,HR,SpO2 had no statistical difference compared with preceding anesthesia.Patients had no naupathia,sick up and headache. Conclusion The low dose spinal-epidural anesthesia has little effect on hemodynamic.It is safe and reliable,can be safely used in hip replacement surgery in elderly patients.
