背景
对手术病人,输血对他们而言或许具有救命的作用。然而异体输血后引起的相关免疫调节或许会增加围手术期患者死亡率增加及手术后患者预后不佳,进而影响其生存质量。 

目的
该研究的目的在于探讨重大腹部肿瘤切除术输血率的发生率对临床结果的影响。 

设计
该研究是以人群为基础的回顾性研究。所有美国医院都参与的美国外科医生质量改进项目,研究人员通过这一数据库获取接受大型腹部手术如切除胰腺,肝、胃部恶性肿瘤等患者的信息,并于2015年7月至8月进行数据分析。

主要结果和措施
研究人员重点关注输注任何数量红细胞的患者及围手术期输血率(时间范围为手术开始至手术后72小时)。次要结果包括患者出现伤口感染、心肌梗死和肾功能不全的发生率。并依据研究期间每年的数据进行趋势分析变化。 

结果
一共有19680名患者(平均年龄为65岁)参与研究,其中有5900名患者(30.0%)接受输血。在这些接受手术的患者中,有13657名患者接受了胰腺切除术,其中有4074名患者输血,占29.8%;有1605名患者接受胃部切除术,输血患者有378名,占23.6%;有4418名患者接受肝切除术,输血患者有1448名,占32.8%。研究期间,患者输血率显著降低(z = −7.89, P <0.001), 2005-2013年患者红细胞输血率降低6.1%,从32.8%降至26.7%。在研究期间术后伤口感染或肾功能不全发生率没有显著变化,但围手术期心肌梗死率增加(0.33%;z = 3.15,P =0.002)。 

结论
这项为期9年的研究表明,接受腹部肿瘤手术的患者围手术期输血率在降低。研究人员表示仍需进行更进一步的研究来评估这些趋势是否反映了手术技术的提高。
