目的通过比较预存式自体输血不同采集时机对择期手术患者术后恢复的影响,探索安全有效的适于预存式自体输血开展的自体血采集时机。方法选择本院2014年1月至2015年5月入院的符合预存式自体输血指征择期手术患者144例,其中试验组:术前2 d内采集自体血患者88例,对照组:手术前3 d及以上患者56例,对2组患者术后1、3 d Hb、Hct、异体血输注率、术中出血量及术后平均住院日进行比较。结果试验组患者术后1 d Hb水平较对照组高(118.2±16.5 g/L,111.5±15.5 g/L,P<0.05),试验组患者术后3 d Hb水平较术后1 d降低(112.5±19.7 g/L,118.2±16.5g/L,P<0.05),但仍高于110 g/L,2组患者术后Hct变化、异体血输注率及术后平均住院天数差异无统计学意义(P>0.05),但试验组平均住院日较对照组缩短(14.7±5.5,18.8±8.9,P<0.05)。结论择期手术患者在术前2 d内进行自体血采集储存对患者术后恢复未产生不利影响,且有助于缩短平均住院日,利于预存式自体输血的开展。
Objective To compare the effect of different collection timing of pre-stored autologous blood transfusion on postoperative recovery in patients undergoing elective surgery and explore the safe and effective timing of autologous blood collection for pre-existing autologous blood transfusion. Methods A total of 144 patients undergoing selective elective transfusion of autologous blood transfusion admitted to our hospital from January 2014 to May 2015 were enrolled in this study. Among them, 88 patients with autologous blood collected within 2 days before operation and the control group d and above in 56 patients. The postoperative Hb, Hct, allogeneic blood transfusion rate, intraoperative blood loss and average postoperative hospital stay were compared between the two groups. Results The level of Hb in experimental group was significantly higher than that in control group at 1 d after operation (118.2 ± 16.5 g / L, 111.5 ± 15.5 g / L, P <0.05) 112.5 ± 19.7 g / L, 118.2 ± 16.5 g / L, P <0.05), but still higher than 110 g / L. There was no statistical difference in postoperative Hct changes, allogeneic blood transfusion rate and postoperative average length of stay (P> 0.05). However, the average length of stay of the experimental group was shorter than that of the control group (14.7 ± 5.5, 18.8 ± 8.9, P <0.05). Conclusions Elective blood collection and storage within 2 days before operation in patients undergoing elective surgery has no adverse effect on the postoperative recovery of patients and helps to shorten the average length of stay and facilitate the development of prefilled autologous blood transfusion.
