Comparing Tranexamic Acid Versus Ecbolics in Preventing Hemorrhage During and After Cesarean Section
The Efficacy and Safety of Tranexamic Acid Versus Uterotonic Agents in Reducing Blood Loss During and After Cesarean Section Among High-risk Patients: a Comparative Study
The study will include 444 pregnant patients undergoing cesarean section in Kasr Al Aini.
Following a proper medical history taking, examination will be done, investigations including laboratory tests and obstetric ultrasound will be done.
Then, the patients will be divided into 4 groups, receiving Oxytocin only (Group 1), Oxytocin + Tranexamic acid (Group 2), Oxtytocin and Misoprostol (Group 3) or Oxytocin and Carbetocin (Group 4) followed by collection of necessary data.

Detailed Description
The study will include (444) pregnant women attending for cesarean delivery in Kasr Elaini hospital (faculty of medicine - Cairo university).
The following will be done to all participants:
- Informed written consent: after discussing the nature of the study as well as the expected value, outcome, and possible adverse effects.
- Full medical history: including full obstetric history and current pregnancy history (entailing the 1st day of LMP).
- Thorough Clinical Examination: general (maternal body weight and vital signs) and full obstetric examination.
- Obstetric ultrasonography: to confirm singleton pregnancy, gestational age and the eligibility of the current pregnancy to participate in the study.
- Preoperative laboratory tests: including prothrombin time, prothrombin concentration, complete blood count, and liver and kidney function tests.
- Group allocation: Before surgery, participants will be randomly and equally assigned into four groups; Tranexamic Acid group, Misoprostol group, Carbetocin group and Oxytocin group. Randomization will be performed using computer-generated random numbers.
- In Oxytocin group (n=111), patients will receive 10 IU oxytocin (Syntocinon, Novartis, Basel, Switzerland) given as infusion in 500 ml lactated ringer/s solution at a rate of 125ml/hour after delivery of the placenta.
- In Tranexamic group (n=111), patients will be given 1 gm (10 ml) TXA (Kapron, Amoun, Egypt) diluted in 20 ml of Glucose 5% (administered as intravenous infusion over 5 minutes, at least 15 minutes prior to skin incision).
- In Misoprostol group (n=111), 400 microgram misoprostol (2 tablets - Cytotec, Pfizer, G.D. Searle LLC) will be inserted intraoperative inside the uterus after delivery of the placenta.
- In carbetocin group (n=111) 100 microgram carbetocin (Pabal, Ferring, Kiel, Germany) will be given as an intravenous bolus dose following the delivery of the placenta.
- In all groups, patients will additionally receive 5 IU oxytocin given as slow intravenous bolus following delivery of the baby.
- All cesarean sections will be done under spinal anesthesia by the following operative steps: pfannensteil incision, transverse lower uterine segment incision, immediate cord clamping (< 30 seconds) and the placenta will be removed by controlled cord traction after its spontaneous separation, closure of uterus in 2 layers, closure of anterior abdominal wall in anatomical manner (adequate hemostasis will be ensured in all operative steps).
- The number and the difference of weight of operative towels (before and after LSCS) and amount of blood in suction unit will be recorded.
- Fluid monitoring will be performed through rate of infusion and urine output. A complete blood count test will be performed 12 hours after delivery.
- Estimated Blood Loss (EBL) will be evaluated as follows:
- The number of operative towels used.
- The difference of weight of operative towels (before and after cs) plus the amount of blood in suction unit (we will calculate 1 gram of weight difference equal to 1 ml blood loss).
- EBL calculation according to the formula which is EBL equals EBV times Preoperative hematocrit minus Postoperative hematocrit divided by Postoperative hematocrit.
- Where EBV is estimated blood volume of the patient in mL (equals weight in kg × 85).
- In Tranexamic Acid group (n=111), the time interval between drug administration and fetal delivery will be recorded.
- All patients will be followed up following the delivery as regard occurrence of primary postpartum hemorrhage (within the first 24 hours), the need for blood transfusion (within the first 24 hours), misoprostol-related side effects (in the first 6 hours) (i.e., shivering, pyrexia >38C0, headache, nausea, vomiting with or without the need for antiemetic drugs), carbetocin - related side effects (i.e., nausea, vomiting, flushing, dizziness, syncope) and the occurrence of thromboembolic events (within one week of delivery).
- The EBL will be compared among the four groups together with occurrence of the above-mentioned drugs side effects.
