The use of a constrained vortex pump compared to a roller pump during adult open-heart operations resulted in no statistically significant differences in total length of stay (12.0 vs 11.6 days) or total patient charges.

Does a constrained vortex pump improve clinical and economic outcomes compared to a roller pump in adults undergoing open-heart operations?
The use of a constrained vortex pump versus a roller pump for arterial blood perfusion during adult open-heart surgery showed no significant differences in clinical outcomes or costs.
Absolute Event Rate: 12% vs 11.6%
p-value: p=NS
The purpose of this study was to compare roller pump and centrifugal pump technologies in routine adult open-heart operations to demonstrate the usefulness of applying a proven method of uniform risk stratification (outcomes research). Objective and readily available preoperative patient data was collected retrospectively on 102 non-randomized and consecutive adult open-heart operations. Group 1 consisted of 51 adult open-heart operations utilizing a roller pump for arterial blood perfusion. Group 2 consisted of 51 adult open-heart procedures utilizing a constrained vortex pump for arterial blood perfusion. A comparison between the frequency of occurrence of 53 different preoperative risk factors in the roller pump group and the centrifugal pump group found no statistically significant differences (p < 0.05). Outcome data for the roller pump and centrifugal pump groups included such data comparisons as intensive care unit length of stay (LOS), post operative LOS, total LOS, total patient charge, reimbursement, morbidity, and mortality, which revealed no statistically significant differences (p < 0.05). Further comparison studies of roller pumps versus centrifugal pumps for arterial blood perfusion should incorporate this kind of comprehensive data comparison and analysis to reasonably assure that both pump groups are very similar before outcomes research is performed.
Dickinson et al. (Thu,) conducted a cohort in Adult open-heart operations (n=102). Constrained vortex pump vs. Roller pump was evaluated on Total length of stay (days) (p=NS). The use of a constrained vortex pump compared to a roller pump during adult open-heart operations resulted in no statistically significant differences in total length of stay (12.0 vs 11.6 days) or total patient charges.
