An improved catheter infusion system is needed for esophageal intraluminal manometry. Using conventional syringe-pump infusion systems undesirably rapid infusion rates of 6 ml per min or more are often needed to achieve accurate recording of esophageal peristaltic pressure. These rapid base line infusion rates are necessitated by the high compliance of syringe-pump systems which causes substantial reduction in the infusion rate during dynamic pressure transients. In this study we tested a hydraulic-capillary infusion system designed to have low compliance. This minimally compliant system yields accurate recording of esophageal peristaltic pressure at infusion rates of 0.6 ml per min or less. We believe that the hydraulic-capillary infusion system is a useful tool for performing both clinical and investigative studies of esophageal motor function.
食管腔内测压需要一种改进的导管输注系统。使用传统的注射泵输注系统时，往往需要6毫升/分钟或更高的不期望的快速输注速率才能准确记录食管蠕动压力。注射泵系统的高顺应性导致在动态压力瞬变期间输注速率大幅降低，因此需要这些快速的基线输注速率。在本研究中，我们测试了一种设计为低顺应性的液压-毛细管输注系统。这种最低顺应性系统在0.6毫升/分钟或更低的输注速率下能准确记录食管蠕动压力。我们认为，液压-毛细管输注系统是进行食管运动功能临床和研究性研究的有用工具。
