摘要
脂肪乳剂中长链甘油三酯所含多价不饱和脂肪酸是多种生物活性物质(如前列腺素等)的前体,它们在成人呼吸窘迫综合征(ARDS)发病中起着极为重要的作用。长链甘油三酯用于ARDS患者可出现一过性动脉血氧分压下降和肺内分流增加,故应慎重大量使用;中链甘油三酯不含生物活性物质前体,但有较高生热作用,故宜慢速输注。理论上长链和中链甘油三酯混合输往或调整多价不饱和脂肪酸比例及使用方法,从而调控生物活性物质的产生,可对ARDS患者起一定的治疗作用。
Polyusaturated fatty acids(PUFA) in long-chain triglycchdes (LCT) serv as precur- sors to the eimids. It is eidrids that plays an irnportant role in the pathaenesis of ARDS. LCT cause temporary reduction in arterial oxygen tension and incrrase intrapulmonary shunt in patients with ARDS. So large dose of LCT should be avoided being used in patients with ARDS. Medium-chain triglyc- erides (MCT) which not containing precrsors of the eicosanoids have higher thermogic effect. Therefore they should be infused slowly. Thooretically, intravenous fat emulsions might be benificial to patients with ARDS by comining LCT with MCT or modulating the content of PUFA and infusing mehas.
