BackgroundBesides reliable efficacy and patient satisfaction, economic efficiency is becoming increasingly more important in postoperative pain management.AimThe present study investigated the effectiveness of two pain pump systems and compared the running costs in treatment.Material And MethodsIn this study 40 patients received an interscalene catheter prior to shoulder surgery. Postoperative pain management was provided via an electronic pump with patient-controlled analgesia (PCA) or a mechanical pump without PCA. Patients kept a pain log. After treatment they were interviewed about their satisfaction with the pump. In addition drug consumption, nursing material, staff time for handling and maintenance of the pumps and preparation of medications pro re nata were assessed.ResultsPostoperative pain levels and patient satisfaction were comparable in both groups. Economically, the electronic pump was more cost-effective than the electronic model for a duration of treatment of 1 and 2 days. With treatment duration of 2 days the costs of both pumps were equivalent; however, the PCA feature of the electronic pump allowed a reduced intake of systemic analgesics on demand.ConclusionBoth pain pump systems provide equally effective pain management, while the electronic model caused less costs. Both pumps offer advantages and disadvantages that should be considered based on local circumstantial demands.
