Intraoperative autotransfusion is used in a variety of surgical procedures with the quantity of blood loss dependent upon numerous factors. These procedures may or may not produce a full autotransfusion bowl. The inadequate removal of contaminants has been correlated to the incomplete filling of bowls, resulting in a condition called “Salvaged Blood Syndrome.” The purpose of this study was to assess the quality of aspirated whole blood after processing with an autotransfusion system using various fill volumes and two wash volumes. An in vitro circuit was designed to mimic the mechanical effects of extracorporeal flow on blood. Twenty-four Baylor-style bowls were filled at 400 mL min−1and washed at 300 mL min−1. Two wash volumes, 1000 and 2000 mL, and three bowl volumes; low, mid, and full, were used in this study. The bowl volumes were determined by using red cell quantities of 60, 100, and 135 mL for the low-fill, mid-fill, and full bowls, respectively. Samples were drawn pre-autotransfusion and post-autotransfusion and analyzed for plasma-free hemoglobin, IL-8, white blood cell count, platelet count, albumin, and total protein. All data were analyzed using one-way analysis of variance (ANOVA) with significance accepted at p≥ .05. Plasma-free hemoglobin levels and hematocrit were concentrated significantly (p< .05) as bowl volume increased. A significant difference in IL-8 levels was found in the wash volumes in the low-fill bowls (p< .02). Platelet count was significantly decreased between the full bowl with 1000 mL wash and the full bowl with 2000 mL wash (p< .0004). Total protein reduction was significantly less in the low-fill bowl with 1000 mL wash as compared to the other bowl treatments (p< .05). In conclusion, the quality of the washed product did not vary significantly between fill or wash volumes, with the exception of the low-fill bowl with 1000 mL wash. |
