Low vs. Very Low Dose of Prophylactic Tranexamic Acid for Bleeding Reduction During Rhinoplasty
- Registration Number
- NCT03070847
- Lead Sponsor
- Bartłomiej Wódarski
- Brief Summary
The purpose of this study is to determine whether very low dose of preoperative tranexamic acid (5mg/kg) is as effective as low dose (10mg/kg) for intraoperational bleeding reduction in patients undergoing elective rhinoplasty surgery.
- Detailed Description
Background
Tranexamic acid is a drug registered for bleeding prevention and reduction. It is on the World Health Organisation (WHO) 'essential drugs list'. Preoperative tranexamic acid efficacy is well proved for doses between 10 and 40 mg/kg and last years and decades publications showed that 'low dose' (10mg/kg) is as efficient as higher doses but connected with less adverse effects.
Objectives
To determine whether 5 mg/kg dose is as effective as commonly used 10mg/kg dose in intraoperational bleeding reduction.
Methodology All patients would be randomised into one of two arms - low and very low dose. Patients, investigators and caregivers would be blinded. Patients would receive intravenous bolus of tranexamic acid at 15 minutes before admission to operation theatre in a dose dependent on the study arm. General, intravenous anesthesia (total intravenous anesthesia) would be performed due to hospital standards. At the end of the surgery total blood volume and adverse effects would be noted. Surgeon would asses surgical field in the Fromm scale.
The survey is planned for a two years timespan or until 50 patients have enrolled (25 for each arm).

Group Intervention Description Very low dose Tranexamic Acid Will receive single bolus of Tranexamic acid. Dose: 5mg/kg diluted in 0,9% sodium chloride (0,9% NaCl), administered IV (in the vein), 15 min before admission to operation theatre. Very low dose Sodium Chloride Will receive single bolus of Tranexamic acid. Dose: 5mg/kg diluted in 0,9% sodium chloride (0,9% NaCl), administered IV (in the vein), 15 min before admission to operation theatre. Low dose Sodium Chloride Will receive single bolus of Tranexamic acid. Dose: 10mg/kg diluted in 0,9% sodium chloride (0,9% NaCl), administered IV (in the vein), 15 min before admission to operation theatre. Low dose Tranexamic Acid Will receive single bolus of Tranexamic acid. Dose: 10mg/kg diluted in 0,9% sodium chloride (0,9% NaCl), administered IV (in the vein), 15 min before admission to operation theatre.
- Primary Outcome Measures
Name Time Method Intraoperational bleeding during rhinoplasty it would be assessed at the end of the surgery by measuring blood volume in the suction device and net weight of all surgical material. (precision balance - 2 mg)
- Secondary Outcome Measures
Name Time Method Adverse effects during rhinoplasty and first day after surgery any adverse effects connected with tranexamic acid usage would be noted
surgical field assesment during rhinoplasty Fromm scale of surgical field would be used
surgery length during rhinoplasty surgical procedure length would be noted
