概括
近20%的儿科心脏手术患者显示阿司匹林无反应. 大多数人对增加的阿司匹林剂量有反应,只有5%的人真正对阿司匹林有抗药性. 使用血小板映射 (TEG-PM) 进行的血小板造影与LTA测试没有相关性.
科学领域:
- 心脏病学 心脏病学
- 儿科手术 儿科手术
- 药理学 药理学是指药理学的学科.
背景情况:
- 亚司匹林 (乙盐酸) 对于预防儿科心脏手术患者的血栓至关重要.
- 阿司匹林不响应影响10-15%的儿童,需要进一步调查.
- 了解阿司匹林反应对于优化这种脆弱人群的血栓预防至关重要.
研究的目的:
- 用光传导聚合度 (LTA) 确定小儿心脏手术患者中阿司匹林响应的患病率.
- 评估阿司匹林的剂量依赖性影响,并比较LTA与血小板映射 (TEG-PM) 的血小板造影.
- 确定阿司匹林不响应的危险因素,并记录不良事件.
主要方法:
- 一项前性队列研究,涉及133名接受心脏手术的儿科患者 (0-18岁),需要用阿司匹林预防.
- 使用LTA (黄金标准) 和TEG-PM评估标准5mg/kg阿司匹林剂量后的阿司匹林反应.
- 对于没有反应的患者,剂量增加到10mg/kg,并重新评估反应.
主要成果:
- 18%的患者 (24/133) 对标准的阿司匹林剂量没有反应.
- 10% (13/133) 的人对增加的阿司匹林剂量 (10 mg/kg) 有反应,表明剂量依赖的效果.
- 5% (7/133) 被LTA识别为抗阿司匹林;TEG-PM结果与LTA没有相关性 (P=.167).
结论:
- 显著比例的儿科心脏手术患者表现出阿司匹林对标准剂量的不反应.
- 大多数没有反应的人可以通过剂量升级来实现阿司匹林反应.
- 虽然可以考虑阿司匹林耐药性测试,但需要进一步研究,将结果与临床结果相关联.

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors
1.1K
Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption
246
Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
