Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Excessive bleeding in the immediate postoperative period, measured by the sum of the debit of all thoracic drains from the moment of arrival to intensive care unit, every hour for 24 hours. The outcome will be considered present if the sum of the chest drainage flow rates is greater than or equal to 150mL / h at any time or part of the hour. | — |
Secondary
| Measure | Time frame |
|---|---|
| Expected outcomes 1: Perioperative myocardial infarction Type 5 in the immediate postoperative period; myocardial infarction associated with miocardial reavascularization surgery verified when the measurement of the ischemic marker troponin in the blood ten times over the reference value, associated with another 1 of the following criteria: new pathological Q waves or new left bundle branch block verified on the electrocardiogram; echocardiogram with new segmentar changes;Angiographic confirmation of new native-bed graft occlusions. ;Expected outcomes 2: Heart Arrhythmias in the immediate postoperative period;medical diagnosis of atrial fibrillation; atrial flutter, supraventricular tachyarrhythmias; tachycardia;ventricular fibrillation; Bradiarrhythmias verified during cardiac monitoring and confirmed by 12 lead electrocardiogram within 24 hours of admission. ;Expected outcomes 3: Blood Transfusion;transfusion of blood or blood components such as: packed red blood cells; fresh frozen plasma; platelet concentrate; cryoprecipitate and factor VIIa within 24 hours of admission.;Expected outcomes 4: Immediate postoperative tympanic temperature behavior, verified by tympanic temperature measurements with intervals of measurements every 15 minutes in the first hour and after this period every 1 hour for 24 hours after paciente admission in intensive care unit | — |
