概括

在中风血栓切除术中,第一通过效应不是良好的临床结果的可靠预测指标. 再输血的时间,患者年龄和成功的再通道化是成功治疗中风的更重要因素.

科学领域:

神经学神经学
干预性神经辐射学
脑卒中医学脑卒中医学

背景情况:

在中风血栓切除术期间一次通过后成功的再输血,称为第一通效应 (FPE),与良好的临床结果有关.
作为评估血栓切除术有效性的指标,FPE的临床意义是不确定的,可能是一个副现象.
这项研究调查了FPE与大量患者队列中有利的临床结果之间的关联.

研究的目的:

为了追溯分析机械血栓切除手术的单中心数据库.
评估第一通过效应 (FPE) 与良好的临床结果的关联 (修改的兰金度表0-2在90天).
为了确定FPE以外的关键指标,预测成功的中风治疗.

主要方法:

连续1047次机械血栓切除术 (2011-2020年) 的回顾性分析.
纳入标准:18岁以上的患者,3个月的临床随访.
统计分析包括单变量和多变量模型,将人口统计,时间指标 (开始再通道化,开始穿刺,穿刺再通道化),通道数和再输血等级 (mTICI ≥ 2B) 与90天的mRS分数相关联.

主要成果:

在685名被纳入的患者中,多变量分析确定了穿刺开始 (OTP),患者年龄和成功的再输血 (mTICI ≥ 2B) 与良好的临床结果有显著关联.
穿刺至再通道化 (PTR) 时间与良好的结果显著相关,当PTR与发病至再通道化 (OTR) 的比率为≥3%时.
时间指标始终与良好的结果相关,而通过次数则没有.

结论:

再输血的时间,患者的年龄和再通道化的程度是中风血栓切除术后良好的临床结果的关键因素.
第一次通过效应 (FPE) 不是成功结果的可靠独立预测指标.
手术时间和再输血的成功是比血栓切除所需的通过次数更重要的指标.

关键词:

First Pass Effect

First Pass Effect

Presystemic elimination, or the first-pass effect, is the metabolism of drugs that reduces their effective concentration at the site of action. Apart from the first-pass effect, the systemic bioavailability of the drug is also reduced by other factors, including incomplete absorption or chemical degradation of drugs.
Depending on the route of administration, drugs can be metabolized in the liver, intestine, lungs, and vasculature. Orally administered drugs are first absorbed through the...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...
