NEJM:腔静脉滤器与创伤患者肺栓塞风险

2019-07-25 MedSci MedSci原创

研究认为,对于抗凝禁忌严重创伤患者,接受早期预防性放置腔静脉滤器治疗不能改善患者症状性肺栓塞或死亡风险

近日研究人员考察了早期放置下腔静脉滤器对存在预防性抗凝禁忌症的严重外伤患者肺栓塞或死亡风险的影响。

240名严重受伤患者(损伤严重度评分>15),存在抗凝血剂禁忌症者,在入院后72小时内随机放置静脉过滤器或不放置过滤器。研究的主要终点是症状肺栓塞或入组后90天全因死亡。次要终点是在受伤后至少存活7天且7天内未接受预防性抗凝治疗的患者的亚群中,第8天至第90天之间出现症状性肺栓塞。

患者平均年龄为39岁,损伤严重程度评分中位数为27分。早期放置腔静脉滤器与不放置滤器相比,没有显著降低症状性肺栓塞或死亡的发生率(腔静脉滤器组为13.9%,对照组为14.4%;风险比为0.99)。对于静脉滤器组46例和对照组34例,损伤后7天内未进行预防性抗凝治疗的患者中,腔静脉滤器组未发生肺栓塞,对照组出现肺栓塞5例(14.7%),其中1例死亡(肺栓塞的相对风险为0)。6例患者发生滤过器内血栓

研究认为,对于抗凝禁忌严重创伤患者,接受早期预防性放置腔静脉滤器治疗不能改善患者症状性肺栓塞或死亡风险。
