Abstract:
Objective To compare the anesthesia effect and adverse effect of subarachnoid block anesthesia with different doses of sufentanil combined with bupivacaine 7.5 mg in aged patients,and explore the suitable dosage of sufentanil.Methods Eighty aged patients with ASA grade Ⅰ-Ⅲ undergoing elective lower limb surgery were divided into 4 groups by random digits table and each group was in 20 cases:group Ⅰ received bupivacaine 7.5 mg,group Ⅱ received bupivacaine 7.5 mg+sufentanil 2.5 μg,group Ⅲ received bupivacaine 7.5 mg+ sufentanil 5.0 μg,group Ⅳ received bupivacaine 7.5 mg+ sufentanil 7.5 μg.The vital signs,degree of motor and sensory nerve blockade and adverse effect were observed.Results Compared with base blood pressure,systolic blood pressure(SBP)and diastolic blood pressure(DBP)in group Ⅰ was significantly decreased after intrathecal injecton 15,30,45,60 minutes(P <0.05).There were no significant differences in the degree of motor nerve blockade in four groups(P > 0.05).The time of sensory nerve blockade in group Ⅰ[(194 ± 58)min]was significantly shorter than that in group Ⅱ,Ⅲ,Ⅳ[(255 ±44),(242 ±58),(308 ± 123)min](P <0.05).The time of sensory nerve blockade in group Ⅳ was significantly longer compared with group Ⅱ and Ⅲ(P < 0.05).The number of pruritus in group Ⅳ(10 cases)was significantly more than that in group Ⅰ and Ⅱ(0,4 cases)(P<0.05).Conclusion Subarachnoid block anesthesia with sufentanil 2.5 or 5.0 μg combined with bupivacaine 7.5 mg in aged patients is safe and effective.
