Aquaflo pump vs FMS 4 pump for shoulder arthroscopic surgery

A prospective controlled trial was carried out to compare two different fluid delivery systems used for shoulder arthroscopy. One an advanced pump system that controls both pressure and flow of fluid delivered, the other an air-driven diaphragm pump that only controls fluid pressure. Blood loss, presence of bleeding vessels and visual clarity were parameters used to assess the pump systems. There was no difference between the pumps in straightforward shoulder procedures. However, complicated and prolonged procedures benefited from the use of the advanced pump system.
