Study summary

This international, multicentre, pragmatic, double-blind, placebo-controlled, randomised trial of TxA versus placebo will enrol 3,300 patients throughout Australia and internationally. This is an effectiveness trial - some elements of the trial are deliberately left to the perioperative clinicians' discretion in order to reflect usual practice and maximise generalisability.

Read the detailed description

Study Aims: To conduct a large, multicentre clinical trial of tranexamic acid (TxA), an antifibrinolytic drug routinely used to reduce bleeding in cardiac and some orthopaedic surgery, in 3,300 patients undergoing major gastrointestinal (GI) surgery. Our specific aims are to investigate whether TxA:

Aim 1: Reduces surgical site infection ("wound infection"), and other healthcare-associated infections (pneumonia and sepsis).

Aim 2: Reduces red cell transfusion in GI surgery. Aim 3: Reduces a pooled composite of any serious postoperative complications, and so increases "days alive and at home up to 30 days after surgery" (DAH30).

Aim 4: To evaluate the temporal effect of TxA on perioperative immune and inflammatory responses.

Study Hypothesis Prophylactic TxA administration in patients undergoing major GI surgery reduces the incidence of surgical site infection (SSI) after surgery when compared with placebo.

Study arms

  • Active comparator
    Tranexamic acid

    At induction of anesthesia and prior to surgical incision a bolus of 0.15 ml/kg ( up to a maximum of 15 ml) , and then commence an infusion of 0.05 ml/kg/h until the end of surgery. The total maximal administered study drug volume will be 30 ml.

    Drug: Tranexamic Acid

  • Placebo comparator
    Placebo

    At induction of anesthesia and prior to surgical incision a bolus of 0.15 ml/kg ( up to a maximum of 15 ml) , and then commence an infusion of 0.05 ml/kg/h until the end of surgery. The total maximal administered study drug volume will be 30 ml.

    Drug: Placebos

Interventions

  • DrugTranexamic Acid

    100mg/ml

  • DrugPlacebos

    Placebo will be 5ml vials calculated to equivalent to the 100mg/ml of active drug.

What researchers measure

Primary outcomes

  1. Incidence of Surgical Site Infection

    defined by the US Centers for Disease Control (CDC)

    Time frame: from surgical incision to 30 days post surgical incision

Secondary outcomes

  1. Red cell transfusion

    Total units given

    Time frame: from surgical incision to hospital discharge (from index surgery) or 30 days.

  2. Other healthcare-associated infections

    sepsis, pneumonia, blood stream infection, UTI, etc; all using CDC-guided definitions

    Time frame: from surgical incision to 30 days

  3. C-reactive protein

    peak

    Time frame: Postoperative Day 3 (three days after surgical incision)

  4. Days at home up to 30 days after surgery (DAH30).

    Time that patient spends at home in the 30 days following surgery

    Time frame: From surgical incision to 30 days
