Utility of cell salvage in women undergoing abdominal myomectomy.

Objective: We examined the use and cost of autologous blood cell salvage in women who undergo abdominal myomectomy.
Study Design: Patients who underwent abdominal myomectomy from 2007-2011 were identified. Use of the cell salvage system and reinfusion of autologous blood in women who had the system set-up were analyzed. Cost was examined by directly reported data.
Results: We identified 607 patients who underwent abdominal myomectomy. Four hundred twenty-five women (70%) had the set-up of the cell salvage system. Cell-salvaged blood was processed and reinfused into 85 of these subjects (20%). In a multivariable model, performance of myomectomy by a gynecologic-specific surgeon (odds ratio [OR], 2.14; 95% confidence interval [CI], 1.28-3.59), >5 myomas (OR, 2.49; 95% CI, 1.27-4.89), and larger uterine size statistically were associated significantly with cell-salvage device set-up. Conversely, having a reproductive-endocrinology-infertility specialist as the surgeon was associated with a significant reduction in cell-salvage system set-up (OR, 0.37; 95% CI, 0.21-0.66). For the women who had cell-salvage system set-up, uterine size of >15-19 weeks of gestation (OR, 3.22; 95% CI, 1.56-8.95) or ≥20 weeks of gestation (OR, 4.62; 95% CI, 1.45-14.73), operating time of >120 minutes (OR, 3.98; 95% CI, 1.70-9.29), and intraoperative blood loss of >1000 mL (OR, 26.31; 95% CI, 10.49-65.99) were associated significantly with a higher incidence of reinfusion of cell-salvaged blood.
Conclusion: The routine use of cell salvage in women who undergo abdominal myomectomy does not appear to be warranted. Cell-salvage set-up appears to be cost-effective only when reinfused, but clinical characteristics cannot predict accurately which women will require reinfusion of cell-salvaged blood.
