Modeling of the Hemoglobin Drop in the Uncomplicated Postoperative Course
August 5, 2019 updated by: Sebastian Jaramillo, Hospital Clinic of Barcelona
transfusion-related decisions in the perioperative setting are often complex due to acute variations in the hemoglobin levels, which typically experience a progressive decrease within days.
This process, commonly referred to as "hemoglobin drop" or "hemoglobin drift", has been observed to be highly variable among patients and reliant on several variables, such as the volemic status, fluid balance and blood loss.
Although it has been investigated and some predictors have been identified, postoperative hemoglobin drop remains unpredictable and is not fully clarified.
In consequence, hemoglobin levels' variations are frequently misunderstood, hindering the decision to transfuse.
