ABSTRACT
Objective To study the influence of sufentanil on analgesic effect and hemodynamics during recovery period of general anesthesia in elderly patients.Methods Eighty patients with general anesthesia were randomly divided into 4 groups (20 cases in each group).Ten min before surgery ended patients in each group were intravenous injected different dose of sufentanil:group S1 with sufentanil 0.2 μg/kg,group S2 0.4 μg/kg,group S3 0.6 μg/kg,and group C (control group) with saline 5 ml.The time of spontaneous breath restores,the time of summon opening eyes and extubation,the cases occurred cough,nausea,vomiting during recovery period were recorded and the VRS pain scores and Ramsay score 10 min after extubation were also recorded.Mean arterial pressure (MAP) and the heart rate (HR) were recorded before the anesthesia induction(T0),stopped anesthetic (T1),pre-extubation (T2),5 min and 10 min after extubation (T3 or T4)Results As group S1 and S2 compared with group C,there was no significant difference on the time of spontaneous breath restores,the time of summon opening eyes,and the time of extubation and leaving the operating room (P ＞ 0.05).However,there was significant difference on the time of spontaneous breath restores ((7.3 ± 4.1) min vs (10.2 ± 4.7) min),the time of summon opening eyes ((8.1 ± 3.1) min vs (11.2 ± 3.7)min),the time of extubation ((12.3 ± 3.1) min vs (16.3 ± 5.9) min),and the time of leaving the operating room((21.4 ±3.0)min vs (24.2 ±3.5)min) between the group S3 and group C(P＜0.01 or P ＜0.05)Patients occurred cough in group S1,S2 and S3 were less than those in group C (P ＜0.05),but there was no significant difference on the occurrence of nausea and vomiting between group S1-3 and group C (P ＞ 0.05)There was significant difference on VRS pain score and Ramsav score between group S1-3 and group C(P ＜0.01).MAP and HR were increased in all points of time as compared with T0 (P ＜ 0.05 or P ＜ 0.01).And there was significant difference on MAP and HR between group S1-3 and group C (P ＜ 0.05 or P ＜ 0.01).Conclusion Before the end of anesthesia sufentanil 0.2 ～ 0.4 μg/kg intravenous injection could be able to enhance analgesic effect,stabilize hemodynamics and do not affect regain consciousness in elderly patients.
