From: Can the prophylactic administration of tranexamic acid reduce the blood loss after robotic-assisted radical prostatectomy? Robotic Assisted Radical Prostatectomy with tranEXamic acid (RARPEX): study protocol for a randomized controlled trial

Parameters Definitions
Hospital stay Days from initial operation to hospital discharge plus any readmission within 30 days
Console time Time of console surgeon activity (min)
Postoperative hemorrhage Evidence of blood loss from drains, based on ultrasonography or CT
Transfusion rate The number of blood transfusions
Urinary leakage Evidence of creatinine level > 500 μmol/l and volume of the drain output exceeds 200 ml/24 h, confirmed on cystography
Lymphorrhea Evidence of creatinine level < 500 μmol/l, hematocrit < 0.2, and volume of the drain output exceeding 200 ml/24 h, no urinary leakage on cystography
Intraabdominal fluid collection Collection of fluid measuring ≥ 3 cm associated with clinical or laboratory abnormalities
Symptomatic fluidothorax Fluid in the pleural cavity associated with respiratory distress or a need to evacuate the fluid
Thromboembolism Unilateral limb swelling, acute respiratory insufficiency, based on ultrasonography or CT
Myocardial infarction Increase of serum concentration of CK-MB and troponin and/or the following ECG changes: new Q waves ≥ 0.04 in duration, new persistent ST elevation, and/or depression
Brain stroke Presence of neurological symptoms, findings on CT scan or MRI
Pneumonia Presence of a new infiltrate on chest X-ray, as well as the following: body temperature > 38 °C, abnormal elevation of WBC, or positive sputum, and requiring antibiotic treatment
Acute renal failure Serum creatinine > 300 μmol/l and/or need for dialysis
Wound infection Surgical site infection associated with laparotomy that develops during the initial hospital stay
Urinary tract infection Culture-positive urine, pyuria, or bacteriuria on urinalysis requiring antibiotic treatment
