Summary

The objective of this study is to investigate the effect of tranexamic acid (TXA) administration on the outcome of cesarean-hysterectomy in women with suspected Morbidly Adherent Placenta (MAP; placenta accreta, increta, percreta).

Detailed description

This trial is a randomized, double blind, placebo controlled trial to quantify the effects of the preoperative administration of tranexamic acid on estimated blood loss and blood product utilization in women undergoing cesarean-hysterectomy for suspected MAP. Subgroup analyses will be performed for laboratory results (coagulation studies, electrolytes, complete blood count), urine output, hemodynamic parameters, return to OR for continued bleeding, post-operative complications (thromboembolism, wound separation, infection, fever), and length of hospital stay. Eligible patients will be randomized to receive either TXA or placebo. Women eligible for inclusion will be identified during their prenatal course or on admission to the hospital prior to surgery. They will be offered participation in the study after appropriate counseling regarding the equipoise regarding TXA and its use in pregnancy, and following a question and answer period they will be consented, and assigned a study number. A randomization table will be generated by the Texas Children's Hospital Investigational Pharmacy, using balanced blocks of 8, and will maintain control of the randomization to ensure blinding of participants and the clinical investigators. Randomization will occur when an order for study medication will be sent on a paper requisition to the Texas Children's Hospital Investigational Pharmacy, and a randomization number will be assigned to correspond to the study number. Ideally, this order will be sumbitted 24h prior to scheduled surgery, but may be submitted for urgent cases by calling the Texas Children's Clinical Pharmacy, and delivering the paper requisition to the 7th Floor Main Pharmacy. The Investigational Pharmacy will prepare study medication (Tranexamic acid I.V. or Normal saline as placebo) as determined by the randomization. The medication (whether study medication or placebo) will be packaged in identical syringes. Sealed, opaque envelopes will be available to the PI or an assigned designee to permit unblinding (linking randomization number and study number) only in the event of a clinical emergency involving a study partipant during times at which the Investigational Pharmacy is closed (nights, weekends, holidays). Once a patient has been randomized, the outcome in hospital will be collected even if the study medication is interrupted or not actually given.

Conditions

• Placenta Accreta

Interventions

Type	Name	Description
DRUG	Tranexamic Acid (TXA)	1g Tranexamic Acid (TXA) will be given at the time of delivery. If in 30 minutes, heavy bleeding continues, a 2nd dose will be administered.
DRUG	Sodium Chloride 0.9%	Dose 1: 1 gram - to be administered by intravenous injection at an approximate rate of 1 mL/minute to all randomized women approximately 10 minutes prior to induction of anesthesia Dose 2: 1 gram - If 30 minutes after beginning the cesarean section there is significant bleeding as defined by the need for the transfusion of 4 or more units of blood products, or if there is a rebleed within the 24 hours after the first dose, a second dose may be given. To be administered by intravenous injection at an approximate rate of 1 mL/minute. The trial treatment injections should not be mixed with blood for transfusion, or infusion solutions containing penicillin or mannitol.
