Observation on the clinical application of target-controlled infusion of propofol guided by Narcotrend for anesthetic induction in renal transplantation patients / 临床麻醉学杂志

ABSTRACT

Objective To observe the hemodynamic change and stress reaction of target-con-trolled infusion (TCI)of propofol guided by Narcotrend for anesthetic induction in renal transplanta-tion patients.Methods Forty patients (25 males,1 5 females,aged 21-38 years,ASA grade Ⅲ orⅣ)undergoing related living donor kidney transplantation were randomly divided into two groupsgroup A and group B (n =20).Group A was induced using TCI system with propofol under the moni-toring of Narcotrend.Group B was induced with propofol manually.HR,MAP,Narcotrend index (NTI),blood glucose (Glu)and plasma cortisol (Cor)were measured before induction (T0 ),before tracheal intubation (T1 ),and 1 (T2 ),3 (T3 ),and 5 (T4 )minutes afterwards.Results HR and MAP at T1 were lower than those at T0 (P < 0.05 )in two groups,they were significantly lower in group B than in group A at corresponding points(P <0.05).HR and MAP in group B increased sig-nificantly (P <0.05)and were significantly higher than those in group A (P <0.05)at T2 and T3 . There was no obvious difference in Glu and Cor between T0 and T2-T4 in group A.Glu and Cor at T2-T4 were obviously higher than those at T0 (P <0.05)in group B and those at corresponding points in group A (P <0.05).Conclusion TCI of propofol guided by Narcotrend in renal transplantation pa-tients can better control the depth of anesthesia,attenuate the stress reaction caused by tracheal intu-bation,and keep hemodynamic smooth during anesthesia induction.
