Abstract

To observe the effect of intravenous low dose tramadol on awake time and extubation response in elderly patients at different time of recovery from general anesthesia. 60 elderly patients were randomly divided into tramadol group (intravenous tramadol 0.7mg/kg subgroups 30, 20 and 10 minutes before the end of operation, expressed as Ⅰgroup、Ⅱgroup and Ⅲ group respectively) and the control group. The time of extubation, awake time and adverse reactions were observed, VAS visual analogue score and Robertson consciousness score were performed. The VAS visual analogue score at 45 minutes after operation in tramadol group was significantly better than that in control group (P < 0.05), and the incidence of restlessness was low. The awake time was prolonged obviously in Ⅲ group (P < 0.05) with Robertson consciousness score at 5 minutes decreased after operation(P < 0.05), and awakening delayed in 4 cases. The incidence of restlessness is higher in Ⅰgroup than the other two tramadol subgroups. Low dose tramadol can inhibit the extubation reaction during the recovery period of general anesthesia in the elderly patients. Tramadol is used at 20 minutes before the operation to wake up quickly, with less restlessness and delayed recovery. It may be the best time to use tramadol in the recovery period of general anesthesia.
