Clinical effect of target-controlled intravenous anesthesia of remifentanil in elderly patients undergoing surgery
Objective To observe the effect of target-controlled intravenous anesthesia of remifentanil in elderly patients undergoing surgery.Methods 40 elderly patients were divided into an experimental group and a control group by random number table method,with 20 patients in each group.The control group received fentanyl anesthesia,and the experimental group received target-controlled intravenous anesthesia of remifentanil.The satisfaction,sensory block onset time,block onset time,incidence of adverse reactions,depression and anxiety score,and quality of life score were compared between the two groups.Results The total satisfaction of the experimental group(95.00%)was higher than that of control group(60.00%)(P<0.05).The experimental group had sensory block onset time of(2.38±0.62)min and motor block onset time of(6.34±1.02)min,which were shorter than(2.96±0.52)and(7.54±1.16)min in the control group(P<0.05).The incidence of adverse reactions in the experimental group(5.00%)was lower than that in the control group(30.00%)(P<0.05).After intervention,the experimental group had depression score of(12.48±3.26)points and anxiety score of(11.05±4.24)points,which were lower than(16.59±3.13)and(15.43±4.19)points in the control group(P<0.05).In the experimental group,the psychological function score was(80.16±4.28)points,the material life status score was(81.28±4.61)points and the social function score was(80.13±3.24)points,which were higher than(71.37±4.64),(72.13±4.62)and(70.92±3.13)points in the control group(P<0.05).Conclusion Target-controlled intravenous anesthesia of remifentanil shows good effect for elderly surgical patients.Patients are more satisfied with the anesthesia effect,and their sensory block onset time and motor block onset time are relatively shorter.It is safer,and is worthy of clinical application and promotion.
