摘要
目的:探讨CYP3A4*1G基因多态性对下腹部手术患者舒芬太尼镇痛效果的影响。方法:选取择期全身麻醉下行下腹部手术的患者120例,年龄20~65岁,ASA I级或I级,接受术后患者自控镇痛(PCA)。采用焦磷酸测序法检测CYP3A4*1G基因多态性,根据基因型将患者分成野生型纯合子(*1/*1)组、突变型杂合子(*1/*1G)组和突变型纯合子(*1G/*1G)组。于麻醉诱导前(T0)、气管插管后1 min(T1)、切皮时(T2)、拔气管导管时(T3)和拔管5 min后(T4)各时间点抽取非静脉输液侧肘静脉血,测定血浆皮质醇(Cor)和血管紧张素I(Ang-I)值,并监测患者平均动脉压(MAP)、心率(HR)。记录患者静脉PCA(PCIA)24 h内舒芬太尼的消耗量和药物不良反应(术后恶心、呕吐、呼吸抑制)。结果:1*1G/*1G组T1、T2和T3时的MAP、HR、Cor,Ang-I均低于*1/*1组和*1/*1G组(P〈0.05);②3组患者术后VAS的比较差异无统计学意义(P〉0.05),而达到相同的镇痛效果①*1G/*1G组患者消耗的PCIA舒芬太尼量为(49.8±10.2)μg,与*1/*1组(64.6±10.9)μg和*1/*1G组(62.5±12.7)μg相比均减少(P〈0.01),*1/*1G组和*1/*1组该指标差异无统计学意义(P〉0.05)。结论:CYP3A4*1G基因多态性是引起舒芬太尼药效学个体差异的遗传因素之一。
Objective: To investigate the effects of CYP3A4*1G genetic polymorphism on analgesia with sufentanil in lower abdominal surgery. Methods: One hundred and twenty patients with ASA Ⅰ or Ⅱ, aged 20-65 years who underwent elective lower abdominal surgery under general anesthesia were recruited into this study. Patient-controlled analgesia(PCA) treatment was given after operation. Genotyping of CYP3A4*1G was carried out by pyrosequencing. The patients were assigned into 3 groups according to their genotypes: group I wild homozygote, group Ⅱ mutation heterozygote and group Ⅲ mutation homozygote. MAP and HR were monitored before induction of general anesthesia(T0), after intubation 1 min(T1), at skin incision(T2) and extubation(T3), and at 5 min after extubation(T4). Plasma cortisol(Cor) and angiotension Ⅱ(Ang-Ⅱ) were measured as well. PCA sufentanil consumption and adverse effects were recorded during the fi rst 24 h after surgery. Results: 1MAP, HR, Cor and Ang-Ⅱ at T1, T2 and T3 were lower in group I than those in group Ⅱ and Ⅲ(P〈0.05). 2No signifi cant differences in the scores of VAS were noted between the three groups(P〈0.05). While similar degrees of pain control was achieved, patients in the *1G/*1G group(49.8±10.2) μg consumed significantly less sufentanil than that in either the wild-type group(64.6±10.9) μg or the *1/*1G group(62.5±12.7) μg(P〈0.01). But there was no signifi cant difference in this index between group Ⅱ and Ⅲ(P〈0.05). Conclusion: CYP3A4*1G genetic polymorphism is one of the factors contributing to the individual variation in patient's response to analgesia with sufentanil.
