Albumin has been regarded as the gold standard for maintaining adequate colloid osmotic pressure in children, but increased cost, the lack of clear-cut benefits for survival, and fear of transmission of unknown viruses have contributed to its replacement by hydroxyethyl starch and gelatin preparations. Each of the synthetic colloids has unique physicochemical characteristics that determine their likely efficacy and adverse effect profile. This review will examine the advantages and disadvantages of the use of different colloid solutions in children with a particular focus on their safety profile.
Dextrans are rarely used because of their negative effects on coagulation and potential for anaphylactic reactions. Gelatin and albumin have little effect on hemostasis, but the disadvantages of gelatin include its high anaphylactoid potential and limited beneficial volume effect. Tetrastarches have significantly fewer adverse effects on coagulation and renal function than the older hydroxyethyl starches and are now approved for children. Dissolving tetrastarches in a plasma-adapted, balanced solution rather than in saline further improves safety with regard to coagulation and acid-base balance.
Tetrastarches offer the best currently available compromise between cost-effectiveness and safety profile in children with preexisting normal renal function and coagulation.
白蛋白一直被视为维持儿童胶体渗透压充足的金标准,但由于成本增加、对生存的明确益处缺乏、以及对未知病毒传播的担忧,白蛋白已被羟乙基淀粉和明胶制剂所取代。每种合成胶体都有其独特的理化特性,决定了其可能的疗效和不良作用谱。本综述将探讨不同胶体溶液在儿童中的使用的优缺点,特别关注其安全性。
由于对凝血的负面影响和潜在的过敏反应,右旋糖酐很少被使用。明胶和白蛋白对止血几乎没有影响,但明胶的缺点包括其高度过敏反应原性和有限的有益容量效应。与较旧的羟乙基淀粉相比,四聚体对凝血和肾功能的不良影响要少得多,现已获准用于儿童。将四聚体溶解在血浆适应的平衡溶液中而不是盐水中,可进一步改善凝血和酸碱平衡方面的安全性。
对于已有正常肾功能和凝血功能的儿童,四聚体在成本效益和安全性方面提供了目前最好的折衷方案。
