Hemobag® method of returning residual CPB blood (study group)
Device: method of returning residual CPB blood ( Hemobag®)
The Hemobag® is a collection reservoir used to facilitate ultrafiltration of the CPB circuit after the patient has been disconnected from CPB).
Other Name: Hemobag®
No Intervention: cell saver
Standard method of returning the residual pump volume to the patient as washed, centrifuged cells (control group)
- Chest Catheter Drainage [ Time Frame: Total amount for the first 24 hours postoperative ]Chest catheters are placed in the mediastinum and sometimes pleural space(s) to collect shed mediastinal blood in the first 24 hours post operative cardiac surgery
- Number of Patient Which Had Blood Products Transfused (RBC's, Platelets, FFP) [ Time Frame: All blood products transfused during index admission, an expected average of 7 days, with the exception of preoperative transfusions. ]These blood components can be a metric of the success of achieving a satisfactory coagulation status.
- Acute Kidney Injury (AKI) [ Time Frame: All creatinines will be recorded and assessed during the entire index admission in order to compare postoperative to preoperative baseline creatinine, an expected average of 7 days. ]Using the Acute Kidney Injury Network (AKIN) definition, serial postoperative creatinines will reflect the presence of AKI when compared with the baseline creatinine.
- Mortality [ Time Frame: Index admission postoperative until the time of discharge, an expected average of 7 days. ]Patients will be followed until hospital discharge
- Number of Participates With Stroke [ Time Frame: Index admission postoperative until the time of discharge, an expected average of 7 days. ]Any neurological defect according to Society of Thoracic Surgery (STS) definition
- Number of Participates on Vasoactive Drugs at 48 Hours Post op Point [ Time Frame: Any intravenous vasoactive drug being used at the 48 hour time point postoperative ]This metric is a surrogate for low output failure and /or vasoplegia depending upon whether inotropes or vasoconstrictors are used.
