ABSTRACT
Objective To investigate the effects of target-controlled confusion of propofol with different concentrations on ventricular repolarization after prophylactic infusion of cefuroxime sodium. Methods Sixty ASA physical status Ⅰ or Ⅱ female patients,aged 18-65 years,undergoing elective gynecological surgery were randomly divided into three groupsgroup P2 (n =20)with TCI 2 μg/ml, group P3 (n =1 9)with TCI 3 μg/ml and group P4 (n =20)with TCI 4 μg/ml.Firstly,they were re-hydrated;secondly,the patients in groups P2,P3 and P4 were intravenous infused with cefuroxime sodium 2.5 g (in 100 ml normal saline)and then target-controlled infused of propofol 2 μg/ml,3μg/ml and 4 μg/ml in target plasma concentration,respectively.At three pionts of timeafter rehy-dration before intravenous antibiotics (T0 ),after intravenous antibiotics before TCI of propofol (T1 ), after TCI of propofol (T2 ),QT interval,QTc interval,Tp-e interval were measured and recorded, respectively.Results Compared with T0 ,QTc [(469.9 ± 34.0)ms vs.(451.2 ± 24.9)ms],Tp-e [(107±25)ms vs.(94±20)ms]and Tp-e/QT (0.260±0.058 vs.0.236±0.043)in group P4 were sig-nificantly prolonged at T1 (P < 0.05 ).Compared with T1 ,QTc of groups P2 [(437.4 ± 24.4)ms vs. (453.3±28.0)ms]and P4 [(438.8±29.9)ms vs.(469.9±34.0)ms]were shortened significantly at T2 (P <0.05).Conclusion Propofol could improve ventricular reporlarization heterogeneity caused by cefu-roxime sodium.
