Analysis of risk factors of intraoperative blood transfusion during liver transplantation

ObjectiveTo explore risk factors of blood transfusion during liver transplantation and construct its prediction model. MethodsThe patients underwent liver transplantation who met the inclusion and exclusion criteria of this study from March 2020 to December 2020 in the Beijing Youan Hospital of Capital Medical University were retrospectively collected. The univariate and logistic multivariate analysis were used to evaluate the risk factors of blood transfusion during liver transplantation and construct the prediction model for intraoperative blood transfusion. ResultsA total of 151 eligible liver transplantation patients were collected in this study, including 51 non-transfusion patients and 100 transfusion patients. The univariate analysis results showed that the differences of primary diagnosis, preoperative hemoglobin (Hb), platelet count, prothrombin time, international normalized ratio, Child-Turcotte-Pugh score, and end-stage liver disease (MELD) score were statistically different between them (P<0.05). The above variables selected by the univariate analysis were selected by stepwise method, then the preoperative Hb and MELD score were selected into the multivariate logistic regression analysis, the results showed that the preoperative Hb≤113 g/L and MELD score ＞14 increased the risk of blood transfusion during liver transplantation [Hb: OR=6.652, 95%CI (2.282, 19.392), P<0.001; MELD score: OR=16.037, 95%CI (6.336, 40.592), P<0.001]. The logistic regression model predicted the area under receiver operating characteristic curve was 0.873 [95%CI (0.808, 0.919), P<0.001], the sensitivity and specificity were 91.0% and 67.5%, respectively, Youden index was 0.674, the accuracy was 86.1%. ConclusionsResults of this study suggest that preoperative Hb ≤113 g/L and MELD score＞14 increase risk of blood transfusion during liver transplantation. Logistic regression model constructed according to preoperative Hb and MELD score has a better sensitivity and specificity of intraoperative blood transfusion.

Evaluation of Risk Factors on Red Blood Cells Transfusion for Patients Underwent Coronary Artery Bypass Grafting Perioperatively

Objective To investigate the risk factors of perioperative red blood cells transfusion for coronary artery bypass grafting (CABG) surgery. Method We retrospectively analyzed the clinical data of 534 patients underwent CABG in our hospital from January to March 2014 year. Those patients were divided into two groups:an on-pump coronary artery bypass grafting group (on-pump group) and an off-pump coronary artery bypass grafting group (off-pump group). There were 185 males and 54 females with a mean age of 59.1±9.4 years in the on-pump group. There were 233 males and 62 females with a mean age of 60.3±8.5 years in the off-pump group. Preoperative data, the relative parameters of extracorporeal circulation, the quantity of red blood cells transfusion of those two groups were compared. risk factors associated with red blood cells transfusion were evaluated by multivariate logistic regression analysis. Results The risk factors of perioperative red blood cells transfusion were age (OR=1.04, 95% CI 1.02-1.07, P=0.001) , weight (OR=0.95, 95% CI 0.93-0.97, P<0.001) , smoking (OR=0.61, 95% CI 0.39-0.94, P=0.027) , preoperative level of HCT (OR=0.90, 95% CI 0.85-0.96, P=0.001) and cardiopulmonary bypass (CPB) (OR=4.90, 95% CI 3.11-7.71, P<0.001) . During CPB, the nadir hemoglobin (nHb) (OR=0.63, 95% CI 0.47-0.84, P=0.002) was the only independent risk factor of red blood cell transfusion. Conclusions Age, weight, non-smoking, preoperative level of HCT, CPB are the risk factors for patients underwent CABG perioperatively and the lowest level of Hb in CPB is an independent risk factor of perioperative red blood cells transfusion.

Impact of Preoperative Use of Low-molecular-weight Heparin on Early Outcomes of Off-pump Coronary ArteryBypass Grafting

Objective To investigate the impact of preoperative use of low-molecular-weight heparin （LMWH） on early outcomes of off-pump coronary artery bypass grafting （OPCAB） . Methods Clinical data of 809 patients undergoingisolated OPCAB from April 1st，2011 to September 30th，2012 in the First Affiliated Hospital of China Medical University were retrospectively analyzed. All the patients were divided into LMWH group and control group according to preoperative use of LMWH or not. In LMWH group，there were 386 patients including 290 male and 96 female patients with their age of 49-81 years，who routinely received anticoagulation therapy with LMWH （LMWH sodium or LMWH calcium，4 000 U twice a day，subcutaneous injection） after discontinuation of anti-platelet therapy until the day before surgery. In the control group，there were 423 patients including 321 male and 102 female patients with their age of 46-78 years，who didn’t receive LMWH or any other anticoagulant after discontinuation of anti-platelet therapy. Postoperative mortality，incidence of perioperative myocardial infarction （MI），operation time，amount of blood loss and transfusion，and incidence of postoperative acute renal injury were compared between the 2 groups. Results Intraoperative blood loss （296±94 ml vs. 249±81 ml，P=0.03），postoperative thoracic drainage （526±159 ml vs. 410±125 ml，P=0.02），blood transfusion （2.6±1.1 U vs. 1.4±0.9 U，P=0.04） and operation time （172±34 min vs. 154±41 min，P=0.04） of LMWH group were significantly larger or longer than those of the control group. There was no statistical difference in postoperative mortality（1.0% vs. 1.2%，P=1.00）or incidence of perioperative MI（4.4% vs. 3.8%，P=0.55）between the 2 groups. Conclusion For OPCAB patientswith stable ischemic heart disease，preoperative management without use of LMWH can decrease operation time and amountof blood loss and transfusion without increasing postoperative mortality or incidence of perioperative MI.

Impact of infusion of red blood cell suspension at different perioperative periods in patients with valvular heart disease: A propensity score matching study

Objective To investigate the impact of red blood cell suspension infusion across various perioperative periods on patients with valvular heart disease. Methods The patients with valvular heart disease admitted to Tianjin Chest Hospital from 2018 to 2020 were selected. Based on the timing of perioperative red cell suspension infusion, patients were categorized into three groups: a group 1 receiving intraoperative red cell suspension infusion, a group 2 receiving red cell suspension infusion within 24 hours after entering the ICU, and a group 3 receiving red cell suspension infusion at both time points. The laboratory results, perioperative blood component infusion volume, and other relevant parameters were retrospectively analyzed. After propensity score matching, the differences in different variables among the three groups were compared. Results After propensity score matching, 102 patients were enrolled, including 52 males and 50 females, with an average age of (61.74±10.58) years. There were 34 patients in each group. The preoperative hemoglobin (Hb) value of the group 2 was significantly higher than that of the group 1 and the group 3, and the amount of red cell suspension and autoblood transfusion was the lowest (P<0.05). In the group 1, Hb was the highest after surgery, Hb was the highest within 24 hours after surgery. HCT was the highest within 24 hours after surgery (P<0.05). The group 1 had the lowest plasma, platelet and cryoprecipitate infusion volumes, and the shortest cardiopulmonary bypass time, aortic occlusion time, postoperative ICU stay and hospital stay, and the least blood loss, total drainage volume (P<0.05). The difference between postoperative Hb and preoperative △Hb1 was significantly increased in the group 1 (P<0.05). Conclusion The intraoperative infusion of suspended red blood cells in patients with heart valves can be used to indicate to clinicians that patients have a better prognosis at discharge, review and follow-up.
