We set out to compare two pump systems, one in which pressure alone could be controlled and the second in which pressure and flow could be controlled separately. Assessments were carried out by two observers independently. A variety of arthroscopic procedures were studied including arthroscopy of the knee, anterior cruciate ligament reconstruction, arthroscopy and acromioplasty of the shoulder, and arthroscopy of the elbow and ankle. We found that both systems used a similar amount of fluid. However, the operative time was significantly decreased with separate control of pressure and flow. This was related to the fact that there was better visualization and better technical ease with the latter pump. There was significantly less extravasation in the soft tissues. Therefore, based on our assessment, pumps that separately control pressure and flow are significantly better than pumps that control pressure alone. There is distinct advantage in less operative time, greater visualization, technical ease, and less soft tissue extravasation.
我们着手比较两种泵系统，一种只能控制压力，另一种能分别控制压力和流量。评估由两名观察者独立进行。研究了多种关节镜手术，包括膝关节镜检查、前交叉韧带重建、肩关节镜检查和肩峰成形术以及肘关节和踝关节镜检查。我们发现两种系统使用的液体量相似。然而，压力和流量分别控制时，手术时间显著缩短。这与以下事实有关：后一种泵能提供更好的视野，操作更简便。软组织中的渗液也明显减少。因此，基于我们的评估，能分别控制压力和流量的泵明显优于只能控制压力的泵。在缩短手术时间、提高视野清晰度、操作简便性以及减少软组织渗液方面有明显优势。
