EVALUATION OF AN IMPROVED ILEUS MONITORING-SYSTEM FOR INTESTINAL MOTILITY

To observe the recovery of normal intestinal movement and the effects of peristalsis-promoting agents in patients with intestinal obstructio n, an ileus monitoring system using the balloon method was simultaneou sly compared with that using the infusion method in 24 patients, To in itiate the balloon ileus monitoring system, measurement was started at a setting of 0 after connecting a transducer to the balloon inflation channel of a decompression tube, The recording sensitivity was 20 mmH g/cm, and the speed of recording was 5 mm/min. The sensitivity of the infusion method was found to be 0.70 +/- 0.17 times that of the balloo n method, and therefore the balloon method was considered to be more a ccurate, The findings of this study show how useful this ileus monitor ing system is for observing the motility of intestinal obstruction.
