The Effect of Local Application of Tranexamic Acid Versus Placebo on Postoperative Complications in Plastic Surgery

Phase 4RecruitingNCT06270407

St. Olavs Hospital3,000 enrolled

Overview

Study objective: This is a study to investigate whether applying the drug tranexamic acid (TXA) onto a surgical wound surface may affect the incidence of surgical complications such as re-bleeding needing intervention, wound complications such as infection, wound rupture or seroma, or if it may increase the risk of blood clots. Eligible patients: Patients undergoing plastic surgical procedures with wounds that would normally receive application of TXA to reduce bleeding after surgery. Study intervention: Participants will receive a single local application of study drug onto their wound surfaces at the end of surgery. Study drug will be identical looking ampoules which contain either TXA or placebo (saline). Neither participants nor study personnel will know the contents of the ampoules.

Any serious postoperative complication needing intervention, specifically re-bleeding, wound infection, wound rupture, or the occurrence of blood clots for the first 30 days after surgery will be registered through the following interventions: * Screening of patient medical records * Distribution of an electronic self-report form (eForsk®) to participating patients at postoperative day 30 * Follow-up phone call to verify data after day 30. The study is terminated after the final phone call. All study data will be registered in an electronic, pseudonymous web-based registration form (eCRF/Viedoc®). Number of participants: To assess the effect of TXA on the defined surgical complications compared to placebo, 1500 patients are needed in each group. Data monitoring committee: A data monitoring committee consisting of a group of independent scientists will be appointed for this study to monitor the safety and scientific integrity of this human research intervention.

Outcomes

Primary Outcomes

Postoperative re-bleeding

* The primary objective is to demonstrate that topical application of TXA is superior to placebo (saline) in preventing postoperative bleeding needing intervention within the first 10 days after surgery. Thus, the null hypothesis to be tested in relation to the primary estimand is as follows: * Null hypothesis: Re-bleeding needing intervention, defined as the dicotome variable occurrence or absence of one of more of the below defined events within the first 10 postoperative days, occurs with the same incidence in wounds treated with topical TXA versus topical placebo (saline). One or several of the following will qualify as case: * Re-operation * surgical exploration or evacuation * aspiration of hematoma * blood transfusion * external extra compression due to hematoma * Alternative hypothesis: Re-bleeding as defined above occurs less often with TXA than placebo (saline)

Time frame: 10 days

Secondary Outcomes

Postoperative wound infection

* Null hypothesis: Wound infection needing intervention, defined as the dicotome variable occurrence or absence of one of more of the below defined events with within the first 30 postoperative days, occurs with the same incidence in wounds treated with topical TXA versus topical placebo (saline). One or several of the following will qualify as a case: * Extra outpatient follow-up * Re-operation or surgical revision * Antibiotic treatment. * Alternative hypothesis: Wound infection as defined above occurs more often with TXA than placebo (saline)

Time frame: 30 days

Postoperative wound rupture

* Null hypothesis: Wound rupture needing intervention, defined as the dicotome variable occurrence or absence of one of more of the below defined events with within the first 30 postoperative days, occurs with the same incidence in wounds treated with topical TXA versus topical placebo (saline). One or several of the following will qualify as a case: * Extra outpatient follow-up * Re-operation or surgical revision * Alternative hypothesis: Wound rupture as defined above occurs more often with TXA than placebo (saline)

Time frame: 30 days

Postoperative seroma

* Null hypothesis: Seroma needing intervention, defined as the dicotome variable occurrence or absence of one of more of the below defined events with within the first 30 postoperative days, occurs with the same incidence in wounds treated with topical TXA versus topical placebo (saline). One or several of the following will qualify as a case: * Active aspiration of seroma * Passive spontaneous drainage of a significant volume of seroma * Alternative hypothesis: Seroma as defined above occurs more often with TXA than placebo (saline)

Time frame: 30 days

Postoperative thromboembolic events

* Null hypothesis: Postoperative thromboembolic events, defined as the dicotome variable occurrence or absence of one of more of the below defined events with within the first 30 postoperative days, occurs with the same incidence in wounds treated with topical TXA versus topical placebo (saline). One or several of the following will qualify as a case: * Deep venous thrombosis * Pulmonary embolus * Cerebral or coronary infarction * Alternative hypothesis: Thromboembolic events as defined above occurs more often with TXA than placebo (saline)

Time frame: 30 days
