腰椎术后自体血回输引流与单纯引流的对比研究

目的 了解腰椎术后自体血回输引流和单纯引流对患者预后的影响.方法 以本院骨科2018年8月～2020年9月住院行腰椎后路开放内固定+融合术的患者为对象,按术后采用的不同引流方式分为自体血回收引流组:从术后采用自体血回输装置引流的患者中随机抽取50名;单纯引流(对照)组:从术后采用引流袋引流的患者中随机抽取50名.回顾性...

Autologous blood transfusion drainage and simple drainage after lumbar surgery:A comparative study

Objective To investigate the effect of autologous blood transfusion(ABT) drainage system and simple drainage(using drainage bags) on the prognosis of patients after lumbar surgery. Methods The patients admitted to the Department of Orthopedics of our hospital from August 2018 to September 2020 who underwent posterior open lumbar internal fixation and fusion were divided into two groups according to different drainage methods adopted after surgery: 50 patients were randomly selected from the patients who received postoperative ABT system for drainage as ABT group, and 50 patients were randomly selected from the patients who received postoperative drainage by drainage bag as simple drainage bgroup(the control group). The postoperative drainage volume, actual postoperative drainage, total dominant blood loss, total autologous blood transfusion volume, as well as the postoperative anemia indexes, infection indexes and albumin levels in d1, d3 and d7 of the 2 groups were retrospectively analyzed. Results The gender, age, operation duration and operation segment of the 2 groups were comparable(P>0.05), and preoperative Hb, Hct, ALB, WBC, NE%, intraoperative blood loss, intraoperative autologous blood transfusion volume and actual postoperative drainage volume were similar(P>0.05).There were no significant differences in Hb, Hct, ALB, WBC, NE% and CRP in postoperative d1, d3 and d7, as well as in preoperative and postoperative Hb, Hct and ALB, and in postoperative and preoperative WBC, NE% and CRP(P>0.05). The postoperative drainage volume(mL) and total dominant blood loss(mL) in ABT group and the control group were 554.40±176.82 vs 337.80±102.43, and 1 048.40±282.87 vs 791.80±277.02, respectively(P<0.05). Conclusion The use of ABT drainage system after lumbar surgery increased the drainage volume compared with simple drainage, but the improvement of anemia, albumin and infection was not obvious. ABT system should not be used routinely for drainage after lumbar surgery.
