Abstract

Background

Two anaesthetic machines, the "Primus®" and the "Zeus®" (Draeger AG, Lübeck, Germany), were subjected to a cost analysis by evaluating the various expenses that go into using each machine.

Methods

These expenses included the acquisition, maintenance, training and device-specific accessory costs. In addition, oxygen, medical air and volatile anaesthetic consumption were determined for each machine.

Results

Anaesthesia duration was 278 ± 140 and 208 ± 112 minutes in the Primus® and the Zeus®, respectively. The purchase cost was €3.28 and €4.58 per hour of operation in the Primus® and the Zeus®, respectively. The maintenance cost was €0.90 and €1.20 per hour of operation in the Primus® and the Zeus®, respectively. We found that the O2 cost was €0.015 ± 0.013 and €0.056 ± 0.121 per hour of operation in the Primus® and the Zeus®, respectively. The medical air cost was €0.005 ± 0.003 and €0.016 ± 0.027 per hour of operation in the Primus® and the Zeus®, respectively. The volatile anaesthetic cost was €2.40 ± 2.40 and €4.80 ± 4.80 per hour of operation in the Primus® and the Zeus®, respectively.

Conclusion

This study showed that the "Zeus®" generates a higher cost per hour of operation compared to the "Primus®".
