320排CT容积灌注对百草枯致化学性肺损伤的早期评价

320排CT容积灌注对百草枯致化学性肺损伤的早期评价摘要

目的：本研究旨在探讨320排CT容积灌注对百草枯致化学性肺损伤的早期评价。

方法：选择2018年1月至2019年12月在我院接受治疗的百草枯中毒患者50例，均行320排CT容积灌注检查，不良反应及安全性均得到保证。根据CT容积灌注数值计算相关参数，进行组间比较。

结果：CT容积灌注检查发现50例患者均呈现不同程度的肺实变和肺野浸润。肺实变和野浸润类型为浸润/结节型、支气管肺炎型和肺不张型。320排CT容积灌注检查分析发现，处于急性期的患者PCT、CRP、IL-6等炎症指标均升高，血氧分压PaO2与FiO2比值下降。随着治疗的进行，以上指标趋于缓解或正常化。同时，通过320排CT容积灌注还可进行肺部微循环及肺泡腔通透性分析，早期揭示肺部病变的生理变化，为临床提供及时有效的治疗方案。

结论：320排CT容积灌注可对百草枯致化学性肺损伤进行早期评价，并得到广泛推广和应用。
