Transfusions
Conditions
Brief summary
The transfusion nomogram, integrating preoperative variables, may effectively predict intraoperative transfusion in major abdominal surgery.
Interventions
OTHERNo intervention (observational study)
This is an observational study aimed at developing and validating a predictive model for perioperative blood transfusion. The study utilizes retrospective clinical data from surgical patients to identify key risk factors associated with transfusion requirements. No experimental intervention will be applied to participants, as the study solely focuses on data analysis and model development.
