Efficacy of Intraoperative Use of Tranexamic Acid in Reducing Blood Loss During Telescoping Nail Application in Osteogenesis Imperfecta - Randomized Control Trials

The aim of this study is to assess the effective of intraoperative use of tranexamic acid in reducing blood loss during telescoping nail application in cases of osteogenesis imperfecta.

Detailed Description

Osteogenesis imperfecta (OI) is a rare inherited pathology that consists of abnormal type one collagen synthesis that affects all structures in the body. The most important and early sign of this pathology is the appearance of fractures after low-energy trauma, progressive bowing of long bones, joint instability, and chronic bone pain. The most used classification is the one created by Sillence that initially had four types and now is expended to more than 15 types. A new nomenclature was published in 2014 in order to simplify the classification and help understand such an intricate pathology. Clinically, all systems in the body are affected, but changes to the musculoskeletal are the most severe; besides, a variable degree of bone brittleness is present. Patients are suffering from severe hyperlaxity, short stature, scoliosis, progressive bowing of the limbs, and chronic bone pain due to continuous microfractures.

The surgical treatment of osteogenesis imperfecta (OI) is negatively influenced by clinical features such as osteoporosis, limb deformities and bone changes caused by bisphosphonate therapy. Blood loss during telescoping nail application in patients with Osteogenesis Imperfecta is a serious problem especially patients with Osteogenesis Imperfecta type III are considered at high risk of blood loss during surgery because of capillary fragility and an altered platelet function.

Tranexamic acid (TXA) is an antifibrinolytic drug that has been shown to be effective in reducing blood loss and the need for transfusions after several orthopaedic surgeries.

However, the effectiveness of tranexamic acid use in application of telescoping nail in osteogenesis imperfecta still remains unclear and no previously available study about this subject. The purpose of this study is to assess the effectiveness of intraoperative use of intravenous (IV) tranexamic acid in reducing total blood loss and transfusion rates for patients who will be operated with telescoping nail application for osteogenesis imperfecta.

Each patient with osteogenesis imperfecta, who consecutively will undergo telescoping femoral nail application with intraoperative use of tranexamic acid during 2022-2023, will be recruited in the study.

A total of 40 patients undergoing telescoping femoral nail application for osteogenesis imperfecta will be including in a prospective randomized study.

Taking detailed history and full clinical examination to exclude the presence of any medical disorder that prevents use of Tranexamic acid. Preoperative lab investigations are Complete Blood Count (CBC) to determine Hemoglobin HB level and Hematocrit value preoperatively.

Operations will be performing under general anesthesia, no tourniquet is using, and the intraoperative regime will be the same for all patients. Patients will be dividing into 2 groups; in group A (control); patients receiving no tranexamic acid, in group B (case); patients receiving 10-15mg/kg or 1g of tranexamic acid intravenously, given 30 minutes before skin incision in telescoping femoral nail application followed by another dose of intravenous tranexamic acid (10-15mg/kg; body weight average 1g) at time of wound closure.

Intraoperative blood loss shall be quantified by measuring irrigation fluid and the weight of surgical sponges used to dry the field intraoperatively by the researcher plus amount of blood in suction drain.

Comparison of blood loss between patients with first femoral osteotomy and patients with previous recurrent femoral osteotomies.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Control patients
Closed Envelope for group A (control); patients receiving no tranexamic acid. With Double-Blind Study in which the participants and observers are unaware of who receives tranexamic acid. The total blood loss (TBL), intraoperative blood loss (IBL), postoperative blood loss (PBL), hemoglobin (HGB) levels and Hematocrit value (Hct) on preoperatively (pre-op) and postoperatively, and amount of allogenic blood transfusion were recorded. Furthermore, the general information was also compared between groups.
Drug: Tranexamic acid
Tranexamic acid (TXA) is an antifibrinolytic drug that has been shown to be effective in reducing blood loss and the need for transfusions after several orthopaedic surgeries.

Experimental: Case patients
Closed Envelope for group B (case); patients receiving tranexamic acid intravenously and topically. With Double-Blind Study in which the participants and observers are unaware of who receives tranexamic acid. The total blood loss (TBL), intraoperative blood loss (IBL), postoperative blood loss (PBL), hemoglobin (HGB) levels and Hematocrit value (Hct) on preoperatively (pre-op) and postoperatively, and amount of allogenic blood transfusion were recorded.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of change in mean blood loss in tranexamic acid group.
Time Frame: Baseline

Based on determining the main outcome variable, the estimated minimum required sample size is 40 patients (20 in each group).

The sample size was calculated using G*power software 3.1.9.2., based on the following assumptions:

Main outcome variable is intraoperative blood loss in cases of Osteogenesis Imperfecta undergoing telescoping nail application which receive tranexamic acid vs. not received it.

Main statistical test is one sided t-test to detect the difference between the two groups.

Alpha = 0.05, Power = 0.80, Effect size = 0.81, Allocation ratio= 1
