Abstract:

【Abstract】 Objective To explore the clinical effect of hip-joint replacement surgery in 80 years or older patients under unilateral combined spinal-epidural anesthesia. Methods A total of 130 cases in our hospital from 2009 to 2011 undergoing hip joint operation, at the age of 80-96, ASA Ⅱ-Ⅲ,.were randomly divided into control group(n=65) and observation group(n=65). In the observation group,.L3-L4 puncture with unilateral combined spinal-epidural anesthesia were applied,.and L2-L3 puncture using epidural anesthesia was applied in the control group..Anesthetic effects of the two groups were observed..Results The onset time and total-block time of anesthesia in the observation group was significantly faster than that in the control group(P<0.05). The heart rate in two groups of patients before and after anesthesia had no significant change..The systolic pressure,.diastolic pressure,.mean arterial pressure after anesthesia in controls fluctuated much more than that in control group.(P<0.05)..The anesthetic effect in the observation group was better than control group. Conclusion Unilateral combined spinal-epidural anesthesia has the advantages of quick effect, analgesia and muscle relaxation effect. With little respiratory and circulatory side effect, the methods can be used safely and effectively in the anesthesia for elderly patients.
