Association Between FSTL1 and Postoperative Pulmonary Complications on Pediatric Within Living Donor Liver Transplantation:a Prospective Cohort Analysis
Association Between FSTL1 and Postoperative Pulmonary Complications on Pediatric Within Living Donor Liver Transplantation:a Prospective Cohort Analysis
The goal of this observational study is to identify the association between FSTL1 elevation and acute lung injury (ALI) after pediatric liver transplantation.The main questions it aims to answer what the risk factors are for ALI in children and to evaluate the predictive value for the development of ALI.Participants will be divided into non-ALI group and ALI group according to whether they had ALI in a week after liver transplantation.Researchers will compare the difference between the two groups and use multivariate logistic regression analysis to screen the risk factors of ALI, and receiver operating characteristic(ROC) curve was used to evaluate the predictive efficacy of risk factors.
Postoperative pulmonary complications(PPC) are complicated diseases with high morbidity and mortality for pediatric after living donor liver transplant (LDLT), Acute lung injury(ALI) after LDLT is a common and complex pulmonary complication, it is leading causes of disability and death,both in the acute and long-term postoperative period, the identification of effective prediction model involved in ALI is urgent and highly demanded.In order to observe the effect of follistim like protein 1(FSTL1) on the incidence of ALI who underwent LDLT, and explore the related mechanism, the investigators aim to collect more than 400 infant patients underwent LDLT from May 2023 to December 2023 in our single-center prospective study. Basic clinical data of children were recorded, including age, gender, alanine aminotransferase (ALT), aspartate aminotransferase (AST), International Normalized ratio (INR), childhood end-stage liver disease score (PELD) and other indicators.The expression levels of serum FSTL1 were recorded immediately after induction of anesthesia (T1), 10 minutes at anhepatic stage (T2), 30 minutes at new hepatic stage (T3) and immediately after abdominal closure (T4). Murray score was used to determine whether ALI occurred one week after LDLT, and the children were divided into non-ALI group and ALI group. Postoperative mechanical ventilation time, ICU stay time, total length of hospital stay and mortality during hospitalization are recorded.
The primary outcome utilised a regression approach to adjust for potential confounders associated with ALI and FSTL1. Multivariate logistic regression analysis was used to screen the risk factors of ALI, and ROC curve was used to evaluate the predictive efficacy of risk factors.
