Abstract :

Background This study aimed to evaluate the association between intraoperative blood loss and myocardial injury after non-cardiac surgery (MINS), which is a severe and common postoperative complication. Methods We compared the incidence of MINS based on significant intraoperative bleeding, defined as an absolute hemoglobin level Results We stratified a total of 15,926 non-cardiac surgical patients with intraoperative hemoglobin and postoperative cardiac troponin (cTn) measurements according to the occurrence of significant intraoperative bleeding; 13,416 (84.2%) had no significant bleeding while 2,510 (15.8%) did have significant bleeding. After an adjustment with inverse probability weighting, the incidence of MINS was higher in the significant bleeding group (35.2% vs. 16.4%; odds ratio, 1.58; 95% confidence interval, 1.43-1.75; p Conclusion Intraoperative blood loss appeared to be associated with MINS. Further studies are needed to confirm these findings. Clinical registration The cohort was registered before patient enrollment at https://cris.nih.go.kr (KCT0004244).
