Comparison of effect of TCI administration and constant rate administration in maintenance of anesthesia in thoracic surgery
Objective To investigate the effect of target controlled infusion(TCI)administration and constant rate administration in maintenance of anesthesia in thoracic surgery.Methods A total of 70 patients who underwent thoracotomy in our hospital were divided into an observation group and a control group according to random number table,with 35 cases in each group.The control group maintained anesthesia by constant rate administration,and the observation group maintained anesthesia by TCI administration.The hemodynamic indexes[heart rate(HR),mean arterial pressure(MAP),and blood oxygen saturation(SpO2)]at different time points[before anesthesia(T0),after intubation(T1),at the beginning of surgery(T2),at the end of surgery(T3)],recovery time,anesthetic dosage and occurrence of complications were compared between the two groups.Results HR at T1,T2 and T3 of the control group was lower than that of this group at T0,and HR at T2 was lower than that of this group at T1 and T3(P<0.05).MAP at T1 and T2 in the control group was lower than those at T0 and T3 in this group,and MAP at T3 was higher than that at T0 in this group(P<0.05).SpO2 at T1 and T3 in the control group were lower than those at T0 and T2 in this group(P<0.05).MAP at T1 of the observation group were higher than that of this group at T0,T2 and T3,and MAP at T2 were lower than that of this group at T0 and T3(P<0.05).Comparison of HR and SpO2 levels at T0,T1,T2 and T3 of the observation group,the difference was not statistically significant(P>0.05).Compared with the control group,the change trend of observation group was more stable.The recovery time of(8.49±2.11)min in the observation group was shorter than(12.54±2.06)min in the control group,and the anesthetic dosage of(1223.06±40.29)mg was less than(1268.57±56.71)mg in the control group.The difference was statistically significant(P<0.05).The complication rate of the observation group was 5.71%,which was lower than 22.86%of the control group,and the difference was statistically significant(P<0.05).Conclusion In the process of thoracotomy,the anesthesia maintenance effect of TCI administration is better.
