Risk Factors for Perioperative Hidden Blood Loss After Intertrochanteric Fracture Surgery in Chinese Patients: A Meta-Analysis.

In our study, female patients, hypertension, time from injury to operation (<2 days), operation time (≥60 mins), fracture type (A2.2 to A3.3), and without anticoagulation were related to increased risks of perioperative HBL in Chinese patients receiving the treatment for the intertrochanteric fracture. We hope this article can guide for surgeons to reduce perioperative HBL as far as possible in the treatment of intertrochanteric fracture.
