Effect of oxycodone on hemodynamics and stress response in general anesthesia induction / 实用医学杂志

ABSTRACT

Objective To investigate the effect of oxycodone and sufentanil with equivalent dose on hemo-dynamics and stress response in general anesthesia induction. Methods One hundred and twenty ASA I orⅡpa-tients with abdominal surgery were randomly divided into oxycodone group(group O,n=60)and sufentanil group (group S,n = 60). Anesthesia was induced with iv oxycodone 0.20 mg/kg(group O)or sufentanil 0.25 μg/kg (group S)respectively,together with iv propofol 2.0 ~ 2.5 mg/kg and cisatracurium 0.2 mg/kg. The patients were tracheally intubated using a single-lumen endotracheal tube. Mean arterial pressure(MAP),heart rate(HR),plas-ma levels of epinephrine(E)and norepinephrine(NE),cortisol(Cor)and blood sugar(Glu)and the occurrence of bucking before anesthesia induction(T0),immediately before intubation(T1),at the moment of intubation(T2), 1 min(T3)and 5 min(T4)after intubation were observed. Results Compared with these at T0,MAP and HR in 2 groups were lower at T1(P0.05). MAP and HR were significantly higher at T2 and T3(P 0.05). Plasma levels of E ,NE,Cor and Glu increased obviously at T2 and T3 in 2 groups(P 0.05). Conclusion Compared with sufentanil ,oxycodone of equivalent dose used for general anesthesia induction can effectively keep smooth on hemodynamics and decrease stress response.
