The Effect of Tranexamic Acid on Haemoglobin Level During Surgeries Around HIP

ABSTRACT

Background: The aim is to assess effect of tranexamic acid on haemoglobin level during surgeries around hip.Material & Methods:This was a prospective follow up study conducted in Mahender Reddy Institute of medical sciences, Chevella over a period of two years from June 2020 to June 2022. A total number of 123 patients who underwent hip surgeries by four different surgeons were selected for this study. Proximal femoral nailing (PFN) for intertrochantric fractures by surgeon A, dynamic hip screw (DHS) for intertrochantric fractures by surgeon B, total hip replacements by surgeon C and hemiarthroplasty by surgeon D were included for this study. The patients were grouped as treatment and control group. The treatment group and control group were selected by purposive sampling. In the treatment group, the patients undergoing surgeries around hip joint received single dose of intravenous tranexamic acid 10 mg/kg body weight 10 minutes before skin incision and equal volume of saline was injected in the control group. Intra operative blood loss was calculated by galvanometric method, weighing the sponges used and soiled by blood during surgery and measuring the amount of blood collected in suction apparatus used during the surgery. The haemoglobin level assessed post operatively and compared with preoperative haemoglobin level. The amount of fluid collected in the post-operative drain were also measured. Results:In the treatment group, 11 patients out of 16 had blood loss below 300 ml, and 5 patients had blood loss more than 300 ml. In control group 5 patients out of 15 had blood loss below 300 ml. 10 patients had blood loss more than 300 ml. Among the 25 patients of hemiarthroplasty group, 11 out of 13 patients of treatment group had drain below 100 ml on the first post operative day. In control group only 2 patients out of 12 had drain less than 100 ml. In DHS group, in the treatment group, 10 out of 11 patients had preoperative and post operative haemoglobin difference less than 1mg/dl. In control group, 12 out of 12 patients had preoperative and post operative Hb difference more than 1mg/dl.Conclusions:Tranexamic acid administrated before surgical incision is efficient in reducing bleeding during common surgeries around the hip joint. Especially surgery where more amount of blood loss was expected, like total joint replacement and hemiarthroplasty, the drug had shown significant benefit compared with the control group.
