Technical and economic feasibility of reusing disposable perfusion cannulas.
The reuse of disposable devices is a potential source of significant cost savings to hospitals.
Venous and arterial perfusion cannulas under new and reused conditions were selected to identify the clinical, safety, technical, logistic, and economic issues that must be addressed to realize these savings.
Single-and dual-stage venous and arterial cannulas from two manufacturers were tested when new, after initial clinical use, and after a single clinical use plus up to nine simulated reuses.
Reuse was simulated by end-to-end bending, coupling and uncoupling of the connectors, and by two 1-hour soaks in plasma at 4° and 40° C, respectively.
Cannulas were decontaminated and then processed by a peracetic acid-based liquid chemical sterilization system after each use/reuse.
Sterilization was validated by eliminating Bacillus subtilis spores from the cannulas on each of five consecutive cycles.
Cannulas were tested for physical changes, functional integrity, biocompatibility, and in vivo performance in sheep.
A cost analysis was also performed.
Sterilization was successfully achieved.
Mechanical changes were less than 20% on all variables studied and were undetectable by experienced cardiac surgeons in selective evaluation.
No clinically important differences were found between new and reused cannulas, even after nine simulated reuses.
Reusing cannulas four times would reduce the cost per procedure from $53 to $19 (64%). (...)
