摘要
将健康雄性贵州小型香猪12只,致体表面积Ⅲ度30％烧伤后,分为早期及延迟喂养两组。分别于伤前及伤后4、7及10天进行门静脉血流量测定及吸收功能测定。结果表明,烧伤后肠道吸收功能随门静脉血流量而变化,而肠道本身的吸收功能并没有大幅度减少。早期肠道营养能明显增加脂肪的吸收量。结果提示,如果能及时而有效地改善门静脉系血循环状况,肠道吸收功能可明显改善,而早期肠道营养则是达到此目的的一个有效手段。
In order to appproach this problem,a new animal model was developed in this study.Results indicated that the intestinal ability of absorbing nutrients was not markedly attenuated,and the reduction of portal blood flow was the primary cause of decrement of absorption of nutrients after burn injury.Therefore it is proposed that a timely and effective restoration of the portal circulation might improve the absorption a- bility.From the results of our present study,it seems probable that early enteral feeding can significantly increase the portal blood flow.
