The goal of this clinical trial is to learn whether giving one dose or two doses of tranexamic acid can safely lower blood loss in older adults having surgery for certain hip fractures. The study includes adults aged 65 years or older who need surgery for pertrochanteric or subtrochanteric hip fractures.
The main questions the study aims to answer are:
* Does giving two doses of tranexamic acid lower the need for blood transfusions compared to one dose? * Does tranexamic acid help keep hemoglobin levels higher after surgery? * Is tranexamic acid safe in this group of participants? Researchers will compare participants who receive one dose of tranexamic acid with those who receive two doses to see which approach works better and is safe.
Participants will:
* Receive either one dose of tranexamic acid before surgery or two doses, one before and one after surgery * Have standard surgery to fix their hip fracture within 48 hours of hospital admission * Be monitored during their hospital stay for blood loss, transfusions, and medical problems * Be followed for up to 90 days after surgery to check for safety A total of 120 participants will take part in this study, which is being conducted at the University Clinic "St. Naum Ohridski" in Skopje, North Macedonia.
