About this study
Official title: Investigation of the Effect of Regional Anesthesia Techniques Applied for Anesthesia of Femoral Neck Fracture Surgery on Perioperative Blood Loss
This retrospective observational study evaluates the effect of different regional anesthesia techniques on perioperative blood loss in patients undergoing femoral neck fracture surgery. Patients who received tranexamic acid were grouped by anesthesia method (lumbar plexus block, spinal anesthesia, or general anesthesia). The primary outcomes were intraoperative blood loss and the change in hemoglobin between the preoperative and postoperative periods. Secondary outcomes were postoperative pain (VAS) and total analgesic consumption during the first 24 hours.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| Group L - Lumbar plexus block | Patients who received lumbar plexus block plus tranexamic acid. | |
| Group S - Spinal anesthesia | Patients who received spinal anesthesia combined with tranexamic acid. | |
| Group G - General anesthesia | Patients who received general anesthesia combined with tranexamic acid. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Intraoperative blood loss
Intraoperative blood loss estimated from the volume in the aspirator container and the blood absorbed in surgical sponges
Measured: Intraoperative (during surgery)
Change in hemoglobin level
Difference between preoperative and postoperative hemoglobin concentration (g/dL)
Measured: Preoperative and within 24 hours postoperatively
Secondary outcomes (2)
Postoperative pain score (VAS)
Postoperative pain assessed using the Visual Analog Scale (VAS), ranging from 0 (no pain) to 10 (worst pain); higher scores indicate worse pain.
Measured: 2, 6, 12 and 24 hours postoperatively
Total analgesic consumption
Total amount of analgesic consumed in the first 24 postoperative hours
Measured: First 24 hours postoperatively
