概括
肺移植期间的周围静脉动脉外体膜氧化 (VA-ECMO) 并没有改善存活率,但增加了术后并发症,包括四肢缺血和更长的ICU停留.
科学领域:
- 心血管外科心血管外科
- 移植医学 移植医学
- 关键的护理关键的护理
背景情况:
- 体外膜氧化 (ECMO) 越来越多地用于肺移植,经常取代传统的心肺绕道.
- 肺移植中中央静脉动脉ECMO (cVA-ECMO) 和外围静脉动脉ECMO (pVA-ECMO) 之间的选择在术后结果方面仍然存在争议.
研究的目的:
- 为了比较肺移植中中央VA-ECMO (cVA-ECMO) 与外围VA-ECMO (pVA-ECMO) 的术后结果.
- 关键的结果指标包括生存率,初级移植功能障碍3级 (PGD3),术后ECMO的需要,以及整体发病率.
主要方法:
- 对包括866名患者在内的五项追溯观察性研究进行了系统审查.
- 数据使用随机效应模型进行了聚合,从重建的卡普兰-梅尔曲线分析了生存率.
- 搜索是在三个数据库中进行的,截至2025年11月.
主要成果:
- 在cVA-ECMO和pVA-ECMO组之间,在72小时后的整体存活率或PGD3发病率中没有发现显著差异.
- pVA-ECMO与术后ECMO的需求增加,体外支持的持续时间长,机械通风的持续时间长,以及长时间的ICU停留有关.
- 需要侵入性治疗的四肢缺血的发生率在pVA-ECMO组显著更高.
结论:
- 虽然生存率和PGD3率相似,但pVA-ECMO与cVA-ECMO相比,与更大的术后发病率和血管并发症有关.
- 管策略的选择应根据患者的风险,手术因素和机构专业知识进行个性化,而不是对一种方法的统一偏好.

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration
263
Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...

Noninvasive positive-pressure ventilation (NIPPV), continuous positive airway pressure (CPAP), and bilevel positive airway pressure (BiPAP) are essential methods in respiratory care. These ventilation techniques offer unique benefits for patients with various respiratory conditions, providing adequate support without requiring intubation. Let's explore how each method is crucial in improving patient outcomes and enhancing respiratory therapy.

Treatment for Pulmonary Arterial Hypertension: Oxygen Therapy for Respiratory Failure
671
Oxygen therapy has emerged as a significant tool in enhancing the quality of life for patients suffering from pulmonary arterial hypertension (PAH). While this therapy has principally been studied on patients with significant hypoxemia, this therapeutic approach helps prevent potential organ damage and can be administered in the comfort of one's home.
Oxygen therapy is vital in increasing and maintaining blood oxygen levels in PAH patients. As a result, it aids in reducing fatigue,...
