BACKGROUND
The trans-tracheal rapid insufflation of oxygen (TRIO) device is less commonly used and is an alternative to trans-tracheal jet ventilation for maintaining oxygenation in a "cannot intubate, cannot oxygenate" (CICO) scenario.
CASE
We report the successful use of this device to maintain oxygenation after jet ventilator failure in a parturient who presented with the CICO scenario during the procedure for excision of laryngeal papilloma.
CONCLUSIONS
A stepwise approach to the airway plan and preparation for an event of failure is essential for good materno-fetal outcomes. The TRIO device may result in inadequate ventilation that can lead to hypercarbia and respiratory acidosis. Hence, it should only be used as a temporizing measure before a definitive airway can be secured.
背景
经气管快速氧注入（TRIO）装置的使用频率较低，是在“无法插管，无法给氧”（CICO）情况下替代经气管喷射通气以维持氧合的一种方法。
病例
我们报告了一例产妇在切除喉乳头状瘤的手术中发生 CICO 场景，在喷射通气失败后使用该设备成功维持氧合的病例。
结论
对于母婴结局良好，制定气道计划和对失败事件的准备的分步骤方法至关重要。TRIO 装置可能导致通气不足，从而导致高碳酸血症和呼吸性酸中毒。因此，它应该仅作为在确定气道安全之前的临时措施使用。
