2018年1月,发表在《Am J Obstet Gynecol》的一项由美国学者进行的双盲、随机、对照试验,比较了布洛芬vs对乙酰氨基酚对具有严重特征的先兆子痫患者产后高血压的影响。

背景:已有研究表明非甾体抗炎药(NSAID)的使用可增加非妊娠成年人的血压。正因如此,美国妇产科医师学会建议产后高血压女性避免使用NSAIDs类药物,然而,缺乏支持该建议的临床证据。

目的:旨在检验假设,即NSAID如布洛芬,对具有严重特征的先兆子痫女性的产后血压控制具有不利影响。

研究设计:分娩后,研究人员将具有严重特征的先兆子痫女性随机分配到每6小时连续口服布洛芬600mg或对乙酰氨基酚650mg组中。分娩后6小时内开始给药,并持续到出院,按需给予阿片类镇痛药治疗爆发痛。

研究药物密封在完全相同的胶囊中,以便对患者、护士和医生设盲。排除标准为ALT或AST>200mg/dL,SCr>1.0mg/dL,传染性肝炎,胃食管返流征,小于18岁,监禁中。首要结局为严重范围高血压的持续时间,其定义为自分娩到末次检测血压≥160/110mmHg的时间(以小时计算)。次要结局为自分娩到末次检测血压≥150/100mmHg的时间、平均动脉压、出院时需要抗高血压药、因血压控制不佳延长住院、产后使用短效降压药进行急性血压控制、使用阿片类药物治疗爆发痛。根据意向治疗原则,研究人员分析了所有结局数据。

结果:154名进行评估的女性中100名符合入组标准,并同意参加试验,将其随机分配到产后布洛芬或对乙酰氨基酚进行一线疼痛控制组中。7名患者交叉使用或未接受分配的研究药物,93人在各自的分组中完成研究程序。

组间基线特征无差异,包括分娩方式、BMI、之前妊娠情况、民族、慢性高血压和分娩前的最高血压。布洛芬vs对乙酰氨基酚组严重范围高血压持续时间无差异(35.3 vs 38.0小时,P=0.30)。两组在自分娩到末次检测血压≥150/100mmHg的时间、产后平均动脉压、产后最高收缩压或舒张压、任何产后血压≥160/110mmHg、产后使用短效降压药进行急性血压控制、产后住院日、因血压控制不佳延长住院、出院时需要抗高血压药、使用阿片类药物进行充分的疼痛控制等次要结局测量上无差异。

在严重范围高血压患者的亚组分析中,对乙酰氨基酚和布洛芬组血压控制的平均时间分别为68.4和56.7小时(P=0.26)。产后6周时,两组在产科就诊率、再住院率、继续使用阿片类药物或继续使用抗高血压药上无差异。

结论:在具有严重特征的先兆子痫女性中,一线使用布洛芬而非对乙酰氨基酚进行产后疼痛控制并不会延长严重范围高血压的持续时间。
