目的:探讨骨科手术异体与自体血回输对患者血清炎症性细胞因子白介素-1β(IL-1β)、白介素-6(IL-6)、白介素-8(IL-8)、肿瘤坏死因子-α(TNF-α)及免疫球蛋白IgA、IgG、IgM的影响。方法:40名骨科手术患者,随机分为两组:自体血回输组20名;异体输血组20名。两组均于麻醉前、术后1d、术后7d采外周静脉血5ml,离心后取血清2ml于低温冰柜保存待检。结果:术后1d IgA、IgG两组均降低,IL-6、IL-8、TNF-α两组均升高,但两组差异有显著性,P<0.05;术后7d与术前相比,两组差异有显著性,P<0.05;IL-1β、IgM两组变化不显著,差异无显著性,P>0.05。结论:炎症性细胞因子IL-6、IL-8、TNF-α及免疫球蛋白IgA、IgG在自体输血、异体输血后变化有显著差异。自体输血对患者免疫功能影响较小,异体输血抑制了患者术后抗感染及伤口愈合等能力,对免疫功能抑制明显。 相似文献

目的探讨成人心血管外科手术回收式自体输血与异体红细胞输注的关系。方法选取2008年1月至2018年12月中国医学科学院阜外医院收治的心血管外科手术患者93 014例,按年度比较分析患者一般资料、手术例数、回收式自体输血使用率及回收红细胞量、异体红细胞输注率及用量。结果与2008年比较,2018年成人心血管外科手术量增长136.6%(10 891例比4 603例),回收式自体输血使用率增长196.0%(89.1%比30.1%),异体红细胞输注率降低65.4%(24.4%比70.5%,P <0.01),平均异体红细胞用量降低64.7%([1.2±0.5)U比(3.4±1.8)U, P <0.01),异体红细胞输注率(用量)随着回收式自体输血使用率的增加而下降(P <0.001),当回收式自体输血使用率达到90%时,异体红细胞输注不再继续降低,而维持在稳定水平。结论回收式自体输血技术可显著减少成人心血管外科手术患者异体红细胞输注,当使用率达到90%时其降低异体红细胞输注效力减弱,需联合应用其他血液管理措施以进一步减少异体红细胞输注。 相似文献

Objective To evaluate the effect of point-of-care hemoglobin/hematocrit (POC HGB/HCT) devices and intraoperative blood salvage on the amount of perioperative allogeneic blood transfusion and blood conservation in clinical practice. Methods A total of46 378medical records of 22 selected hospitals were reviewed. The volume of allogeneic red blood cell and plasma, number of patients transfused, number of intraoperative autologous blood salvage, total volume of autologous blood transfusion, and amount of surgeryin the year of 2011 and 2013 were tracked. Pairedt-test was used in intra-group comparison, whilet-test of two isolated samples carried out in inter-group comparison.P<0.05 was defined as statistically significant difference. Results In the hospitals where POC HGB/HCT device was used (n=9), the average allogeneic blood transfusion volume per 100 surgical cases in 2013 was significantly lower than that in 2011 (39.86±20.20vs. 30.49±17.50 Units,t=3.522,P=0.008). In the hospitals without POC HGB/HCT meter, the index was not significantly different between 2013 and 2011. The average allogeneic blood transfusion volume was significantly reduced in 2013 than in 2011 in the hospitals where intraoperative autologous blood salvage ratio [autologous transfusion volume/(autologous transfusion volume+allogeneic transfusion volume)] was increased (n=12,t=2.290,P=0.042). No significant difference of the above index was found in the hospitals whose autologous transfusion ratio did not grow. Conclusion Intraoperative usage of POC HGB/HCT devices and increasing autologous transfusion ratio could reduce perioperative allogeneic blood transfusion. 相似文献

目的探讨围术期自体输血血液采集方法的改良。方法选取2012年12月至2013年12月湖北省中山医院手术用血患者130例,根据抽签法分为围术期自体输血组和预存式自体输血组,每组65例,围术期自体输血组开始手术时采用自体血液回收仪回收血液,预存式自体输血组在围术期自体输血组的基础上,令患者在择期手术前1个月开始采血,每3~5日1次,每次300~500 m L。记录两组的手术时间、术中输血量、异体输血量、输液量,术后止痛剂用量、肿瘤坏死因子α(TNF-α)和补体C3水平。结果围术期自体输血组异体输血量显著高于预存式自体输血组[(391±43)m L比(92±21)m L,P<0.05]。与术前相比,预存式自体输血组术后血清TNF-α水平[术前(1.19±0.25)mg/L,术后1 d(1.33±0.19)mg/L,术后7 d(1.52±0.21)mg/L]、补体C3水平[术前(116±22)mg/L,术后1 d(120±18)mg/L,术后7 d(119±17)mg/L]表现出上升趋势(P<0.05)。但围术期自体输血组手术前后的血清TNF-α水平[术前(1.19±0.22)mg/L,术后1 d(1.21±0.19)mg/L,术后7 d(1.18±0.18)mg/L]、补体C3水平[术前(115±19)mg/L,术后1 d(132±15)mg/L,术后7 d(175±18)mg/L]比较差异无统计学意义(P>0.05)。围术期自体输血组术后TNF-α水平、补体C3水平均显著低于预存式自体输血组(P<0.05)。结论改良自体输血能得到更多自体血液,能大量减少术中异体输血,提高术后TNFα和补体C3水平。 相似文献

异体红细胞输注在纠正贫血、改善组织氧合的同时,也可能导致输血相关免疫调节,因此可能与术后感染的风险增加相关,但既往研究对此尚有争议。基础研究发现,输血相关免疫调节与输注量相关,陈旧红细胞的免疫抑制作用更为显著,而去白细胞处理有助于减轻输血对免疫系统的负面影响;但临床研究针对上述问题并未得出一致性结论。近年来,随着多中心、大样本真实世界研究不断涌现,大部分针对心脏、骨、肝脏、胰腺、胃肠道、膀胱手术的研究支持输血与术后感染的相关性,但仍存在一定局限性。未来研究可更多着眼于多种术式,延长输血与手术时间间隔的时间范围,将各种感染类型纳入结局,在保证充足样本量的情况下,尽可能准确地定义感染诊断。此方面高质量临床证据,对改善临床血液成分合理使用、改善患者术后结局具有重要意义。 相似文献

目的观察和比较术中等容血液稀释自体输血和异体输血对肿瘤患者围术期机体内环境和凝血功能的影响。方法选择直肠癌、结肠癌和胃癌根治术患者40例,随机分为两组。A组术中输异体全血400mL;B组于手术切皮前放血400mL,同时输入等量羟乙基淀粉,术中自体血回输给患者。结果A组输血后1h及术后24hpH值和HC03一下降较B组明显(P〈0.05);B组稀释后Hb明显低于A组(P〈O.05);血常规其余各值、PT、APTT、FIB在各测定点两组变化一致,两组间均无显著差异(P〉0.05)。结论在一定范围内,等容血液稀释自体输血有利于维持肿瘤患者围术期内环境稳定,等容血液稀释自体输血与异体输血相比对凝血功能的影响差异不显著。 相似文献

Context. The risks of blood transfusion have been studied extensively but the benefits and the hemoglobin concentration at which patients should receive a transfusion have not. Objective. To determine the effect of perioperative transfusion on 30- and 90-day postoperative mortality. Design. Retrospective cohort study. Setting. A total of 20 US hospitals between 1983 and 1993. Participants. A total of 8787 consecutive hip fracture patients, aged 60 years or older, who underwent surgical repair. Main Outcome Measures. Primary outcome was 30-day postoperative mortality; secondary outcome was 90-day postoperative mortality. The "trigger" hemoglobin level was defined as the lowest hemoglobin level prior to the first transfusion during the time period or, for patients in the nontranfused group, as the lowest hemoglobin level during the time period. Results. Overall 30-day mortality was 4.6% (n=402; 95% confidence interval [CI], 4.1%-5.0%); overall 90-day mortality was 9.0% (n=788; 95% CI, 8.4%-9.6%). A total of 42% of patients (n=3699) received a postoperative transfusion. Among patients with trigger hemoglobin levels between 80 and 100 g/L (8.0 and 10.0 g/dL), 55.6% received a transfusion, while 90.5% of patients with hemoglobin levels less than 80 g/L (8.0 g/dL) received postoperative transfusions. Postoperative transfusion did not influence 30- or 90-day mortality after adjusting for trigger hemoglobin level, cardiovascular disease, and other risk factors for death: for 30-day mortality, the adjusted odds ratio (OR) was 0.96 (95% CI, 0.74-1.26); for 90-day mortality, the adjusted hazard ratio was 1.08 (95% CI, 0.90-1.29). Similarly, 30-day mortality after surgery did not differ between those who received a preoperative transfusion and those who did not (adjusted OR, 1.23; 95% CI, 0.81-1.89). Conclusions. Perioperative transfusion in patients with hemoglobin levels 80 g/L (8.0 g/dL) or higher did not appear to influence the risk of 30- or 90-day mortality in this elderly population. At hemoglobin concentrations of less than 80 g/L (8.0 g/dL), 90.5% of patients received a transfusion, precluding further analysis of the association of transfusion and mortality. 相似文献
