简要总结
The purpose of the study is to describe the incidence of complications in brain death adult organ donors.
详细描述
Pathophysiological changes following brain death may complicate the care of brain death donors. These complications negatively affects function of donated organs. Understanding these complications and its incidence is crucial for their appropriate management. The aim of this retrospective observational study is to evaluate the incidence of complications in adult brain death organ donors. Date will be collected from medical records of eligible patients admitted to intensive care unit for suspected brain death in whom brain death was confirmed and who become organ donors.

结局指标
主要结局
Myocardial dysfunction
时间窗: 48hours prior confirmation of brain death to ICU discharge
Myocardial dysfunction is defined as left ventricle ejection fraction under 50% on trans-thoracic echocardiography or S-T segment depression or elevation or T wave negativity or positive troponin serum level
ARDS
时间窗: 48hours prior confirmation of brain death to ICU discharge
ARDS is defined and stratified according to Berlin definition
Renal dysfunction
时间窗: 48hours prior confirmation of brain death to ICU discharge
Renal dysfunction is defined as presence of at least one of these criteria: absolute increase in serum creatinine ≥0.3 mg/dL (≥26.4 μmol/L) or increase in serum creatinine ≥1.5x above baseline or oliguria (urine output \<0.5 mL/kg per hour) for \>6 hours
Coagulopathy
时间窗: 48hours prior confirmation of brain death to ICU discharge
Coagulopathy is defined as international normalised ratio above 1,5 or platelet count below 100 000 per microliter
Catecholamine storm
时间窗: 48hours prior confirmation of brain death to ICU discharge
Catecholamine storm is defined as onset of tachycardia and/or hypertension
Diabetes insipidus
时间窗: 48hours prior confirmation of brain death to ICU discharge
Diabetes insipidus is defines as urine output more than 4ml/kg per hour or urine specific gravity under 1010
Serum lactate level
时间窗: 48hours prior confirmation of brain death to ICU discharge
Maximal lactate level will be evaluated during ICU stay
Hypotension
时间窗: 48hours prior confirmation of brain death to ICU discharge
Hypotension is defined as increase of vasoactive drug dose by 20% or systolic blood pressure lower than 90 mmHg or need for fluid resuscitation after initial normovolemia was achieved
Oxygenation index
时间窗: 48hours prior confirmation of brain death to ICU discharge
Oxygenation index will be calculated as PaO2 divided by FiO2
Hypothermia
时间窗: 48hours prior confirmation of brain death to ICU discharge
Body temperature below 36°C or need for external warming
