NCT ID NCT07494708
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looked at whether placing a drain after knee replacement surgery affects how much hemoglobin drops and whether patients need a blood transfusion. 102 patients were randomly assigned to get a drain or not. The goal is to see if drains help or hurt in terms of blood loss. Results could help guide standard practice.
