Abstract

Interrelationship between dielectric parameters and level of ATPH before and during ischemia, as well as with indices of survival after elimination of strangulation, was estimated on a simulation model of strangulation ileus in rats. The data obtained permit to suppose, that parameter tg δm may be used as effective noninvasive criterion of diagnosis in real time for estimation of the intestinal wall state in strangulation. Resection of the infringed intestine without elimination of strangulation is necessary in tg δm less than 2.20, in tg δm more than 2.36 the elimination of infringement is indicated, because there exist possibility to restore intestinal function after ischemic-reperfusion injury. Tactics of treatment in intermediate meanings of tg δm is not determined, but its measurement before reperfusion may help in estimation of a small intestine viability and choice of surgical tactics in its ischemia.

摘要

在大鼠绞窄性肠梗阻模拟模型上，评估了缺血前后及缺血期间介电参数与ATPH水平之间的相互关系，以及与绞窄解除后存活指标的相互关系。所获得的数据表明，参数tgδm可作为实时诊断的有效非侵入性标准，用于评估绞窄时肠壁状态。当tgδm小于2.20时，需要在不解除绞窄的情况下切除受损肠段；当tgδm大于2.36时，则表明需要解除绞窄，因为存在缺血再灌注损伤后恢复肠功能的可能性。tgδm处于中间值时的治疗策略尚未确定，但在再灌注前测量该参数可能有助于评估小肠活力，并在小肠缺血时选择手术策略。
