详细
论证。呼吸支持已成功用于治疗非毒性肺水肿。无毒性肺水肿和中毒性肺水肿的特征相似,因此呼吸支持对后者可能有效。
研究目的。证明人工肺通气和呼气末正压对氟塑料-4 热降解产物严重中毒的疗效。
材料与方法。研究使用了三只兔子:兔子 1(对照组)、兔子 2(中毒组)和兔子 3(治疗组)。 兔 2 和兔 3 被氟塑料-4 热降解产物(1.5 HLC50,15 分钟)严重中毒。对暴露一小时后的兔 3 进行了人工肺通气和呼气末正压支持(压力控制模式;氧气分数 - 0.3;起始呼气末正压支持 - 5 厘米水柱,潮气量 - 20-25 毫升)。
结果。暴露于氟塑料-4 热分解产物导致兔 2 依次出现间质性和肺泡性中毒性肺水肿,最终在暴露后 13 小时死亡。由于兔 3 在呼吸支持过程中 SaO2 下降,PetCO2 上升(暴露后 3 小时和 5 小时),呼气末正压增加了两次,每次增加 2 厘米水柱(保持给定的潮气量),从而使研究参数恢复正常。暴露后第 7 天,兔 3 的状况与兔 1 的状况没有区别,呼吸系统也未发现任何病理变化。
结论。暴露于氟塑料-4 热分解产物 1 小时后,使用呼气末正压辅助人工肺通气对因严重中毒而出现的中毒性肺水肿具有良好矫正效果。
