Hemoderivative Imputable Complications in Initial Uncomplicated Heart Surgery

Observational Study of Hemoderivative Imputable Complications in Initial Uncomplicated Heart Surgery

Observational Study of Hemoderivative Transfusion Imputable Complications in Initial Uncomplicated Heart Surgery. Inclusion criteria are patients who discontinued the mechanical ventilation up to 6 hours after exiting operation room and who discontinued vasoactive drugs up to the beginning of the second postoperative day.

Blood transfusion might be only a marker of the patient severity.

Criteria for blood transfusion during extra corporeal circulation (if used) is volume expansion need leading to a predictable hematocrit lower than 25%.

Criteria for blood transfusion after extra corporeal circulation or in the postoperative period is a hematocrit below 30% with signs of low cardiac output due to hypovolemia.

Inclusion Criteria:

• Patients with acquired heart disease with indication for surgery and who discontinued the mechanical ventilation up to 6 hours after exiting operation room and who discontinued vasoactive drugs up to the beginning of the second postoperative day.

Exclusion Criteria:

• Patients who received blood transfusion previous to the heart surgery.
