Title: The Value of Tranxemic Acid to Reduce Intraoperative Blood Loss During Elective Cesarean Sections in High Risk Women: A Randomized Controlled Trial
Brief 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)


Options:
A: Inclusion Criteria:

All trauma patients with ongoing significant haemorrhage (systolic blood pressure less than 90 mmHg and/or heart rate more than 110 beats per minute), or who are considered to be at risk of significant haemorrhage, and are within 8 hours of the injury, are eligible for trial entry if they appear to be at least 16 years old. Although entry is allowed up to 8 hours from injury, the earlier that patients can be treated the better.

Exclusion Criteria:

The fundamental eligibility criterion is the responsible doctor's 'uncertainty' as to whether or not to use an antifibrinolytic agent in a particular adult with traumatic haemorrhage. Patients for whom the responsible doctor considers there is a clear indication for antifibrinolytic therapy should not be randomised. Likewise, patients for whom there is considered to be a clear contraindication to antifibrinolytic therapy (such as, perhaps, those who have clinical evidence of a thrombotic disseminated intravascular coagulation) should not be randomised. Where the responsible doctor is substantially uncertain as to whether or not to use an antifibrinolytic, all these patients are eligible for randomisation and should be considered for the trial. There are no other pre-specified exclusion criteria
