• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 160 (actual)

Summary

A full medical history will be obtained from all participants. Obstetric ultrasonography and laboratory tests will be performed.According to group assignment, either 1 g(10 mL) tranexamic acid stored in a dry container at 15 °C-30 °C) diluted in 20 mL of 5% glucose or 30 mL of 5% glucose will be slowly administered intravenously 15 minutes before skin incision over a 5-minute period. Following delivery, patients in both groups will receive an intravenous bolus of 5 IU oxytocin , 1 mL(0.2 mg) intramuscular ergometrine , and 20 IU oxytocin in 500 mL lactated Ringer's solution(infused at a rate of 125 mL/h)

Detailed description

A full medical history will be obtained from all participants. Obstetric ultrasonography and laboratory tests will be performed, including prothrombin time, prothrombin concentration, complete blood count, and liver and kidney function tests. Maternal body weight and vital signs (heart rate, blood pressure, and respiratory rate) will be checked 30 minutes before surgery. According to group assignment, either 1 g(10 mL) tranexamic acid (Kapron, Amoun, Egypt; stored in a dry container at 15 °C-30 °C) diluted in 20 mL of 5% glucose or 30 mL of 5% glucose will be slowly administered intravenously 15 minutes before skin incision over a 5-minute period. Following delivery, patients in both groups will receive an intravenous bolus of 5 IU oxytocin (Syntocinon, Novartis, Basel, Switzerland), 1 mL(0.2 mg) intramuscular ergometrine (Methergin, Novartis, Basel, Switzerland), and 20 IU oxytocin in 500 mL lactated Ringer's solution(infused at a rate of 125 mL/h). Fluid monitoring will be performed through rate of infusion and urine output. A complete blood count test will be performed 24 hours after delivery. On discharge, patients who received tranexamic acid will be given a brief orientation regarding symptoms and signs of a thromboembolic event and will be instructed to contact the investigators immediately if any occurred. All patients will be examined for thromboembolic events at the 1- and 4-week follow-up visits EBL will be calculated according to the formula: EBL = EBV x Preoperative hematocrit-Postoperative hematocrit Preoperative hematocrit where EBV is estimated blood volume (mL; weight in kg × 85). For a two-tailed test at an α level of 0.05, the difference between the two groups regarding the primary outcome measure (EBL) had a power of 1.0 (100%) in a post hoc calculation.
