Intensive Care Med:经支气管纵膈针刺活检时发生脑空气栓塞

2018-02-26 杨中华 脑血管病及重症文献导读

71岁,支气管内超声引导下纵膈淋巴结活检。术中采取经外周静脉清醒镇静,手术后昏睡。

71岁,支气管内超声引导下纵膈淋巴结活检。术中采取经外周静脉清醒镇静,手术后昏睡。

立即头颅CTA检查显示弥漫性空气栓塞(下图),排除了气胸和纵膈气肿。超声心动图和发泡试验排除了卵圆孔未闭。作者认为静脉输液引起的空气栓塞可能性不大:





作者认为肺活检可以破坏血-气接触面(blood–air interface),从而引起空气栓塞。自主呼吸和咳嗽会进一步增加压力梯度,促使空气进入血管

全身性栓塞也可以通过心脏的右向左分流或肺的动脉-静脉吻合,引起动脉空气栓塞。支气管内超声指导下经支气管针检时短暂支气管-血管瘘可以引起动脉空气栓塞,未密封针内的空气和高位淋巴结血管是动脉空气栓塞的危险因素。

手术后立即高压氧治疗,患者神经功能逐渐恢复正常。

FDA批准肺活检穿刺伤口处理设备上市

    2012年12月19日,美国食品与药物管理局(FDA)批准了Bio-Seal肺活组织检查穿刺伤口处理设备上市。该设备可减少经皮穿刺针吸肺活检过程中患者发生气胸的危险。   Bio-Seal系统由预先充满凝胶的注射器和针芯构成,在肺活检完成后,医生可应用该系统经穿刺活检通道并通过针芯注射凝胶,干凝胶和体液接触发生再水化和膨胀,从而进行封堵,防止空气渗入肺脏。凝胶可随

Chest:肺活检增加支气管针吸活检术并发症

    美国德克萨斯大学MD安德森癌症中心的一项研究表明,经支气管肺活检(TBBX)是支气管内超声引导下的经支气管针吸活检术(EBUS-TBNA)(应用)期间引起并发症发生的唯一风险因素。快速现场细胞学评估(ROSE)显著降低TBBX的使用。该论文发表在2013年第4期《胸科杂志》[Chest. 2013; 143(4):1044-1053]。  研究者从美国胸内科医

特发性肺纤维化研究进展与防治策略

客观地说,目前临床医生对纤维化性肺疾病仍知之甚少:病因和发病机制不清楚;在诊断和判断病情、预后方面仍存在很多困惑;重要的是,至今未找到确定有效且不良反应小的治疗药物。然而,这并不等于临床和科研工作毫无建树。事实上,自首次报道间质性肺疾病至今的近 80 年内,经过大量艰苦而细致的工作,人们对这类疾病的认识已取得长足进展,积累了有价值的循证医学证据。 【分类】从单一病理标准到兼顾临床与病
