Intraoperative blood salvage and autotransfusion are commonly used to minimize exposure to banked blood.
Although this technique has been used widely for years, data vary regarding the quality of autotransfused blood.
Salvaged blood may contain plasma, residual heparin, and free hemoglobin released from damaged cells.
All of these factors may contribute to the adverse sequelae sometimes seen with autotransfusion.
For these reasons, we have monitored autotransfused blood to assess its quality.
Intraoperative blood salvage was used during most cardiac procedures and at the discretion of the surgeon in other specialties.
Blood was collected through a double lumen catheter that was anticoagulated with heparin, filtered, centrifuged, and washed with saline.
A sample of the blood was removed for analysis, which included hematocrit, heparin assay, fibrinogen, and free hemoglobin levels.
Over a 6-year period, 1593 patients had intraoperative blood salvage with quality assessment.
The majority of patients underwent cardiac operations (941 patients, 59%), whereas 243 had orthopedic (15%) and 208 had vascular (13%) procedures.
Additionally, there were 127 pediatric patients (8%) and 74 miscellaneous procedures (5%). The highest average yield of salvaged blood was during vascular procedures (1073± 76 mL), whereas orthopedic cases had the lowest yield (378 ± 19 mL) and hematocrit (39%). (...)
