Abstract:
Objective:To explore the risk factors of early infection patients after heart transplantation(HT)and provide references for preventing and treating early infection.Methods:From April 2018 to May 2021, clinical data were retrospectively reviewed for 95 HT recipients treated at Zhengzhou Seventh People's Hospital.They were divided into two groups of infected(n=34)and uninfected(n=61). Gender, age, disease type, preoperative IABP implantation, postoperative intra-aortic balloon pump(IABP)implantation, postoperative extracorporeal membrane oxygenation(ECMO)implantation, preoperative mechanical ventilation, preoperative leukocyte, preoperative lymphocyte, preoperative serum C-reactive protein(CRP), operative approach, APACHEⅡscore, NYHA grade, hemoglobin, cardiopulmonary bypass time, donor heart cold ischemia time, postoperative thoracic drainage tube indwelling time, postoperative gastric tube indwelling time, postoperative urinary tube indwelling time, postoperative acute rejection, postoperative ventilator assisted treatment time and postoperative ICU time.The risk factors of early infection were analyzed by univariate and multivariate Logistic regression analysis.Results:There were 34 cases of early infection after HT and 8 cases died.In infection group, preoperative hemoglobin(female <110 g/L or male <120 g/L), ECMO post-operation, 24-48 h post-operation, APACHE post-operation(>6), postoperative intrathoracic drainage tube indwelling time(≥7 d), postoperative gastric tube indwelling time(≥4 d), postoperative urinary tube indwelling time(≥5 d), postoperative acute rejection(positive), postoperative ventilator assisted treatment time(≥2 d)and postoperative ICU time(≥10 d)were 18 cases(52.94%), 8(23.53%), 30(88.24%), 22(64.71%), 18(52.94%), 20(58.82%), 4(11.76%), 21(61.76%)and 19(55.88%); uninfected group: 16 cases(26.23%), 3(4.92%), 32(52.46%), 24(39.34%), 15(24.59%), 31(34.43%), 1(1.64%), 21(34.43%)and 4(6.56%). Significant inter-group differences existed( χ2=6.778, 5.68, 12.326, 5.623, 7.740, 5.297, 4.489, 6.615, 28.947, P<0.05). Multivariate Logistic regression analysis indicated that 24-48h post-operation, APACHEⅡ score >6(β=1.024, Wald χ2=7.653, OR=2.141, OR95% CI=1.323~4.215), ECMO post-operation(β=1.783, Wald χ2=6.186, OR=5.949, OR95% CI =1.459~24.25), postoperative intrathoracic drainage tube indwelling time ≥7 d(β=0.712, Wald χ2=5.745, OR=1.054, OR95% CI=1.183~6.753), postoperative gastric tube indwelling time(β=0.832, Wald χ2=6.756, OR=1.132, OR95% CI=1.416~8.406), postoperative ventilator assisted treatment time(β=0.745, Wald χ2=6.563, OR=1.212, OR95% CI=1.289~7.346)and postoperative ICU time=1.28(β=1.325, Wald χ2=9.752, OR=2.435, OR95% CI=1.426~6.354)were independent risk factor for early infection after HT( P<0.05). Conclusions:Early infection after HT remains higher.It is significantly correlated with 24-48 h post-operation APACHE II score, ECMO post-operation, postoperative intrathoracic drainage tube indwelling time, postoperative gastric tube indwelling time, postoperative ventilator assisted treatment time and postoperative ICU time.Targeted interventions should be adopted for lowering the incidence of early infection after HT.
