Objective: To evaluate the effect of transfusion-free techniques on the prognosis of liver transplant patients. Methods: The recipients of adult liver transplantation at Tianjin First Central Hospital from August to December 2019 were included in the clinical observation. Liver transplantation without allogeneic blood transfusion was performed through anesthesia management techniques such as acute hemodilution or phlebotomy without volume replacement,maintaining decreased baseline central venous pressure and cell saver. According to the actual results,the patients were divided into two groups: transfusion-free group(n=21) and allogeneic transfusion group(n=28). There were 13 males and 8 females aged of (56.3±11.6) years in the transfusion-free group;and there were 16 males and 12 females aged (54.3±14.2)years in the allogeneic transfusion group. The transplant recipients who had not adopted transfusion management strategy from January to July 2019 were included as control group(27 males and 13 females,aged of (58.9±14.1)years). The clinical data of patients in perioperative period were collected to compare whether there were differences in the recovery of liver function and early complications among the three groups, one-way ANOVA test, rank-sum test, and χ2 test were used for data analysis. Results: The amount of intraoperative blood loss in both the transfusion-free group and the transfusion group was less than that in the control group((454.2±271.3)ml vs.(673.6±333.4)ml vs.(890.3±346.7)ml;q=-6.342,-5.286,both P<0.05).The duration of stay in ICU of the transfusion-free group was less than that of the transfusion group and control group((36.4±9.1)hours vs.(44.3±14.9)hours vs.(58.2±21.1)hours;q=-4.432,-3.824,both P<0.05).The mean ALT level at 7 days after operation was significantly lower in the transfusion-free group than in the control group((56.8±32.1)U/L vs.(89.6±45.6)U/L;q=-3.358,P<0.05). Conclusions: The improvement of multi-disciplinary transfusion management technology aimed at transfusion-free liver transplantation can effectively reduce intraoperative hemorrhage and help to avoid surgical transfusion. Transfusion-free liver transplantation is beneficial to the early postoperative recovery,and its long-term clinical significance is worthy of further clinical research.
目的： 探讨减少或避免肝移植术中输注异体血的系列血液管理改进策略对受者围手术期指标的影响。 方法： 回顾性收集2019年8—12月天津市第一中心医院收治的49例成人肝移植受者资料。根据术中是否输血分为无输血组（21例）和输血组（28例）。无输血组男性13例，女性8例，年龄（56.3±11.6）岁；输血组男性16例，女性12例，年龄（54.3±14.2）岁。所有患者术中采用急性血液稀释、低中心静脉压、血液回收等麻醉管理技术，最大限度地减少肝移植术中出血量。随机选取2019年1—7月未采取输血管理策略的40例移植受者作为对照组，男性27例，女性13例，年龄（58.9±14.1）岁。收集各组患者的围手术期临床资料，比较三组移植术后早期的肝功能恢复及并发症等情况，分别采用方差分析、秩和检验、χ²检验进行数据分析。 结果： 无输血组与输血组术中出血量均少于对照组［出血量分别为（454.2±271.3）、（673.6±333.4）、（890.3±346.7）ml；q=-6.342、-5.286，P值均<0.05］。无输血组ICU住院时间短于输血组和对照组［ICU住院时间分别为（36.4±9.1）、（44.3±14.9）、（58.2±21.1）h；q=-4.432、-3.824，P值均<0.05］，术后第7天无输血组的ALT水平低于对照组［（56.8±32.1）U/L比（89.6±45.6）U/L；q=-3.358，P<0.05］。 结论： 以不输血肝移植为目标开展多学科输血管理技术改进措施，可有效减少肝移植术中出血量，并有助于避免外科输血，且有利于受者术后早期恢复。.
