Blood Transfusion Strategies During Major Surgery (TOPGUN)
The TOPGUN Trial: Threshold for Operative and Postoperative Hemoglobin Trigger for Red Blood Cell Transfusion
The goal of this randomized clinical trial is to address the uncertainty surrounding blood transfusion strategies in the operating room for adult patients undergoing major surgery. The main question it aims to answer is:
Does a higher hemoglobin threshold for blood transfusion during surgery reduce the risk of serious complications or death after surgery compared with a lower hemoglobin threshold?
Researchers will compare a liberal and a restrictive transfusion strategy during surgery and the first few hours of recovery.
Participants will be randomly assigned to one of two blood transfusion strategies. Blood transfusions will be given to maintain either a higher hemoglobin level (90-100 g/L) or a lower hemoglobin level (70-80 g/L) during surgery and while in the recovery room after surgery. Participants will also complete questionnaires about their quality of life and recovery at 30 and 90 days after surgery.

|---|---|
|
실험적: 제한적인 수혈 전략
제한적 수혈 전략은 참가자의 헤모글로빈 수치가 70g/L 미만으로 측정되거나 헤모글로빈 목표 범위를 70-80g/L로 유지하는 경우 적혈구 수혈을 실시하는 것으로 구성됩니다.

참가자의 헤모글로빈 수치가 70g/L 미만으로 측정되거나 헤모글로빈 목표 범위를 70-80g/L로 유지하기 위해 적혈구 수혈을 실시합니다.
이 전략은 수술 중과 수술 후 마취 관리실에서 최대 6시간 동안 준수됩니다.

|
실험적: Liberal transfusion strategy
The liberal transfusion strategy will consist of administering red blood cell transfusion when the participant's hemoglobin level is measured below 90 g/L or to maintain a hemoglobin target range of 90-100 g/L.ed to during surgery and up to 6 hours in the post-operative anesthesia care unit.

기간 |
|---|---|---|
|
30-day overall morbidity or mortality
기간: From randomization to 30 days post-surgery
|
Overall postoperative morbidity and mortality within 30 days after surgery, assessed using the Comprehensive Complication Index (CCI).
Complications will be identified using the Postoperative Morbidity Survey (POMS) and graded according to the Clavien-Dindo classification.
The CCI summarizes all postoperative complications into a continuous score ranging from 0 (no complications) to 100 (death), with higher scores indicating greater postoperative morbidity.

30-day individual perioperative complications
기간: From randomization to 30 days post-surgery
|
The occurrence of individual perioperative complications will be captured using the Postoperative Morbidity Survey (POMS).
Complications will be categorized according to the POMS domains, including pulmonary, infectious, renal, gastrointestinal, cardiovascular, neurological, wound, hematological, and pain-related morbidity.
|
From randomization to 30 days post-surgery
