Impact of Intraoperative Cell Salvage on Concentrations of Antibiotics Used for Surgical Prophylaxis.

Intraoperative cell salvage (IOCS) is used to administer autologous blood lost during surgery. We studied antibiotic disposition through an IOCS system for vancomycin, piperacillin, ampicillin, and cefazolin. Only 2% ± 1% of antibiotic inoculated in whole blood was recovered in the IOCS reinfusion bag, whereas 97% ± 17% was found in the waste.
