右美托咪定對下肢手術(shù)患者血流動力學和術(shù)后恢復的影響
[Abstract]:Objective to investigate the effect of dexmetomidine on hemodynamics and postoperative recovery in patients undergoing lower limb surgery. Methods 300 patients undergoing lower extremity operation in Shanghai Changhai Hospital from January to June 2012 were selected and divided into the observation group and the control group according to the random number method. The patients in the observation group were continuously injected with 0.5 渭 g kg ~ (-1) h ~ (-1) after intravenous injection of 1.0 渭 g/kg dexmetidine 10 minutes after anesthesia induction, while those in the control group were given the same amount of 0.9% sodium chloride solution. The changes of hemodynamics and postoperative recovery index were observed in both groups. Results in the observation group, before the tourniquet was inflated, The heart rate of the tourniquet was significantly slower than that of the control group at each time point (P < 0. 05), and the cardiac output, cardiac index and output of 5min at each time point after the tourniquet inflated and the 5min after the tourniquet deflating were significantly slower than those of the control group at each time point (P < 0. 05) after the tourniquet was inflated and 5 min after the tourniquet exhalation (P < 0. 05). At 5 min after exhalation of tourniquet, the output index per beat was significantly higher than that in control group at the same time point (P < 0. 05). There was no significant difference in recovery time, trachea extubation time and time to leave the operating room between the two groups (P < 0.05). Nausea, vomiting, shivering, abnormal pulse oxygen saturation, upper respiratory obstruction and other complications occurred in both groups, but the incidence of vomiting in the control group was significantly higher than that in the observation group (P0.05). There was no significant difference in the incidence of other adverse reactions between the two groups (P 0.05). The total incidence of adverse reactions in the observation group was 5.3% (8 / 150), which was significantly lower than that in the control group (20.6%) (31 / 150) (P0.05). Conclusion it is feasible to use dexmetomidine in lower extremity surgery, the hemodynamics of patients is stable, and the incidence of postoperative adverse reactions is relatively low.
