为证实绞窄性肠缺血术后低氧血症的情况 ,并希望通过动物实验了解其原因。方法 :临床研究绞窄性肠缺血患儿手术松解恢复肠血运后血氧饱和度并将之与一期手术切肠和单纯性肠梗阻患儿术后血氧饱和度作比较 ,同时实验研究大肠绞窄性肠缺血不同时间 (30′、6 0′)术后肺透性指数的变化情况 ,并进行比较分析。结果 :绞窄性肠缺血手术恢复血供后的血氧饱和度比切肠组和单纯性肠梗阻患儿更低 ,有显著的统计学差异。实验大鼠肺透性指数在绞窄性肠缺血手术后的过程中变化明显。结论 :绞窄性肠缺血手术松解绞窄恢复血运后的过程中有更为明显的低氧血症过程 ,可能是肺泡毛细血管透性增加、氧交换障碍所致。
In order to confirm the situation of postoperative hypoxemia in strangulated intestinal ischemia, and hope that through animal experiments understand the reason. Methods: The clinical study of surgical treatment of strangulated intestinal ischemia in patients with restoring intestinal oxygen saturation and blood oxygen saturation after surgery with intestinal resection and simple bowel obstruction in patients with oxygen saturation compared at the same time Experimental study of colorectal serotonergic ischemia at different times (30 ’, 60’) after the change of pulmonary permeability index, and comparative analysis. Results: The blood oxygen saturation after strangulated intestinal ischemia surgery was lower than that of the group of intestine and simple intestinal obstruction, with significant statistical difference. The lung permeability index of experimental rats changed obviously during the process of strangulated intestinal ischemia. Conclusions: The process of reperfusion and strangulation after strangulation of intestinal ischemia and reperfusion has more obvious process of hypoxemia, which may be caused by increased permeability of alveolar capillary and oxygen exchange disorder.
