Local Infiltration of TranExamic Acid in Surgical Management of Pelvic Organ Prolapse: a Pilot Randomized Clinical Trial
Overview
- Phase
- Phase 4
- Status
- Withdrawn
- Enrollment
- 36
- Primary Endpoint
- Intraoperative quantitative blood loss QBL (mL)
Overview
Brief Summary
Tranexamic acid (TXA) has been demonstrated to reduce blood loss in trauma, orthopedic, cardiac, and plastic surgeries in numerous well-designed and adequately powered studies. As a result of this evidence for benefit, TXA is routinely used to reduce blood loss during these surgeries. There are no studies regarding the use of TXA in urogynecology. The investigators seek to explore the effect and safety of local infiltration of TXA in vaginal reconstructive surgery.
Detailed Description
This is a multicenter, double blinded, pilot randomized clinical trial that will be conducted at UTMB Health, and other participating sites. Each participating site will obtain IRB approval. Women with symptomatic, stage II to IV Pelvic organ prolapse (POP) who plan colpocleisis will be approached to participate. Using the study protocol inclusion and exclusion criteria, patient's eligibility will be determined. All eligible subjects will provide the written informed consent before any research data is collected. All screening assessment will be completed at a preoperative, in-person, clinic visit, and within 60 days of surgery. The subject will then undergo randomization to the local TXA, or Vasopressin, or NS group with the total sample size of 36 female subjects (12 per group). Concomitant procedures for POP or urinary incontinence are permitted and will be based upon the operating surgeons' standard clinical practice and best clinical judgement. The anesthesia team is responsible for preparing the study agents, monitoring intraoperative cardiovascular parameters (blood pressure and heart rate) as well as adverse events, and determining the blood transfusion if needed. Subsequently, the subject will have postoperative follow up at 2 weeks and 6 weeks

Masking Description
The attending anesthesiologist will receive the randomized assignment from the lead research team at UTMB and prepare the diluted study agents. The OR staff, attending surgeon, and learners including fellows and residents are blinded.
