NEJM:心脏术后是否应该严格输血指征(TITRe2试验)

2015-03-15 MedSci MedSci原创

临床上通常会根据患者血红蛋白水平,决定是否输注红细胞悬液。目前对于心脏手术后的病人,严格限制输血指征较放宽指征相对自由的输血,能否降低患者发病率和医疗支出还不明确。

临床上通常会根据患者血红蛋白水平,决定是否输注红细胞悬液。目前对于心脏手术后的病人,严格限制输血指征较放宽指征相对自由的输血,能否降低患者发病率和医疗支出还不明确。

因此Gavin J. Murphy等人进行了一项多中心、平行对照试验。研究纳入英国17个中心的大于16岁,行了非紧急的心脏手术患者,术后血红蛋白水平小于9g/dl,将其随机分为两组:严格输血指征组(HB<7.5g/dl才能输血)、放宽输血指征组(HB<9g/dl即可输血)。研究观察的初始指标:随机试验3个月后严重感染(败血症或伤口感染)、缺血性事件(永久性中风、心肌梗塞、肠梗阻、急性肾功衰)。研究者们同时评估了患者从术后当天到术后三个月的医疗花费(不包括手术费用)。

研究共纳入2007患者,有4名退出试验。最终有1000随机分到严格输血指征组,1003在放宽输血指征组。严格组和放宽组比较,两组输血率:53.4% vs. 92.2%;初始指标:35.1% vs. 33%(OR 1.11,95% CI 0.91-1.34,P=0.30)。同时数据表明,严格组其死亡率更高,4.2% vs. 2.6%,HR 1.64,95% CI 1.00-2.67,P=0.045。除开初始指标观察的严重术后并发症,其余并发症发生率在严格组和放宽组的发生率:35.7% vs. 34.2%。两组间医疗花费无显著差异。

该研究结果表明,对于心脏手术后病人,在术后并发症发病率和医疗花费上,严格输血指征(HB<7.5g/dl)并不优于放宽输血指征(HB<9g/dl)。

JACC:RBC输血提高血小板反应,但不影响炎症和血栓形成

该实验致力于研究红细胞(RBC)输血过程是否会在冠状以及非冠状动脉患者体内上调血小板凝集和炎症反应的程度。 在健康人体的体外实验中,RBC输血会加速血小板的活化和凝集,这为急性冠状动脉综合征(ACS)患者进行RBC输血之后,复发性缺血性事件和死亡率有所增加的现象,提供一种可能的解释。   在63位研究对象(33位患有ACS,28位没有患ACS)进行输血的前后,分别测量其血小板活

JAMA:促红素和成分输血并不改善急重颅脑损伤患者的预后

据7月2日发表在《美国医学会杂志》(JAMA)发表一项随机对照研究,比较严重颅脑损伤时,促红素(EPO)与安慰剂对比,对患者脑损伤恢复的影响。 这项随机对照试验,共招募200人(EPO组102人,安慰剂组98人),均属于闭合性颅损伤,损伤6小时内,住入神经病学急诊ICU的患者。这项研究从2006年5月份开始,持续到2012年8月结束。采用析因设计策略,比较EPO对能否改善患者6个月月后Glasg

Nat Med:年轻血液可提高老年大脑功能

这是一个听起来有些古怪的实验:把年轻小鼠的血液注入到年老小鼠的体内之后,后者的大脑神经细胞会出现增长,并且在迷宫实验中的导航能力也会增强。“就像这些年老的大脑通过年轻血液进行了‘充电’一样,”研究作者之一、斯坦福大学神经病学和神经科学教授托尼·维斯-科雷(Tony Wyss-Coray)说道。他们的研究发表在近期的《自然-医学》(Nature Medicine)上。 研究者们认为,如果相同的结果

Spine :取髂骨做脊柱融合可增加输血率并延长手术时间及住院日

基于髂骨的骨传导、骨诱导和成骨特性,取髂骨植骨常用来辅助脊柱融合。但取髂骨相关的致病率常为临床担心的问题。术后取骨部位疼痛为常常遇到的问题,但报道不一,急性痛见于2.8%到27.9%的患者,慢性痛见于2.4%到60%的患者。也有学者认为此问题被夸大,持续痛可能源于原发脊柱疾病。 其他关于取髂骨的潜在问题包括,血肿,感染,骨盆骨折和神经麻痹,另外还有与取骨本身有关的失血增加,手术和麻醉时间
