Crit Care:输注白蛋白可预防透析间低血压

2021-01-07 MedSci原创 MedSci原创

在需要HD的低白蛋白血症患者中,透析前输注白蛋白可减少低血压发生并改善体液清除率。

血液透析间低血压(IDH)是间歇性血液透析(IHD)常见的并发症,门诊患者约有15%至50%,在住院低白蛋白血症患者中更为常见。IDH无法充分过滤液体,增加了血管通路血栓形成、血液透析(HD)过早终止和死亡的风险。透析之前和透析期间输注白蛋白已被用于IDH治疗,但各研究的结果各不相同。近日,危重病医学领域权威杂志Critical Care上发表了一篇研究文章,研究人员旨在评估低白蛋白血症患者在IHD期间输注白蛋白预防IDH的疗效。

研究人员对65名低白蛋白血症(白蛋白<3 g/dl)且在住院期间需要HD的AKI或ESKD患者进行了一项随机、交叉试验。在每次透析开始时,患者随机接受100 ml的0.9%氯化钠或25%白蛋白静脉输注。透析期间每15至30分钟记录一次患者的生命体征和超滤清除率。研究人员通过文献报道的不同定义来评估IDH,并记录与低血压事件有关的所有症状以及透析期间的干预措施。

65名患者接受了249次透析治疗;平均年龄为58岁(±12),男性46岁(70%),平均体重为76(±18)kg。根据定义,白蛋白治疗期间IDH的发生几率较低。根据肾脏疾病结果质量倡议的定义,低血压风险显著降低;(NS组为15%,白蛋白组为7%,p=0.002)。接受0.9%氯化钠输注的患者的最低透析间SBP明显比白蛋白组的患者要低(NS为83 vs. 白蛋白组为90mmHg,p=0.035)。白蛋白治疗患者总的超滤率明显更高[NS-8.25 ml/kg/h(−11.18-5.80),而白蛋白疗法则为8.27 ml/kg/h(12.22-5.53),p=0.011]。

由此可见,在需要HD的低白蛋白血症患者中,透析前输注白蛋白可减少低血压发生并改善体液清除率。在这些高危患者中,输注白蛋白可能有益于改善HD的安全性,并实现体液平衡。

CLIN CHEM:基于白蛋白校正钙研究,在三级医院环境中的钙营养状况的错误分类

临床实验室测量总钙并校正白蛋白浓度以预测钙营养状况。研究人员将总钙和校正钙(Adj-Ca)与离子钙(Ca 2+)进行了比较,以正确分配钙营养状况。根据错误分类的频率确定限制低蛋白血症患者的Adj-Ca报告的效果。 研究人员连续收集24个月的实验室测量结果。由改良的Payne公式计算Adj-Ca。在停止报告白蛋白<3.0g / dL的患者的Adj-Ca后,收集了6个月的进一步前

白蛋白应该是低血容量患者液体复苏的**胶体吗?

血流动力学管理是危重症和急诊医学的一项主要治疗挑战。在患者从入院到出院整个康复过程中起着关键作用。在恢复血流动力学稳定期间,复苏是液体管理的主要指标之一,经常是救命治疗,需以正确的剂量、速率,并选择正确的液体种类尽可能快的给予。不幸的是,这些核心的液体治疗在科学文献中并未得到一致性和可靠证据的支持。对正确的患者应用正确的液体的管理仍是一个争议根源的准则。然而,在2013年EMA和FDA发布了限制H

尿微量白蛋白:早期肾损伤的“信号兵”

王阿姨患有糖尿病,复查时医生需要检测她的尿微量白蛋白,同时需要王阿姨留取24小时尿,王阿姨说:“我之前测过尿常规,蛋白也没有加号,没有留尿啊,怎么这次不一样?”其实,和王阿姨一样,一些糖尿病或者肾脏疾病患者面对这样的检查,也有同样的困惑:到底什么是尿微量白蛋白,和尿常规检测的尿蛋白有什么区别呢?
