Invasive airway access by emergent cricothyrotomy remains an essential treatment modality in "can't intubate/can't ventilate" scenarios. Although numerous commercial devices are available, limited comparative data exist with regard to the ventilation and oxygenation parameters of these devices. We report a case of severely compromised respiratory function while using the Quicktrach II, a commercially available emergency cricothyrotomy device. Because of oxygenation and ventilatory insufficiency, our patient required emergent removal of the device and surgical tracheostomy to improve respiratory function. When confronted with a difficult airway, anesthesiologists and surgeons should be aware of commonly encountered cricothyrotomy devices and their potential limitations.

紧急开颅手术后通气和氧气受损：对次优侵入性气道的处理建议。

在“不能插管/不能通气”的情况下，紧急环切开孔术对气道的侵袭仍然是一种必不可少的治疗方法。尽管有许多商用设备可用，但是关于这些设备的通风和充氧参数存在有限的比较数据。我们报告了使用Quicktrach II（市售紧急环切开术设备）时呼吸功能严重受损的情况。由于氧合作用和呼吸机能不全，我们的患者需要紧急移除器械并进行气管切开术以改善呼吸功能。当面对困难的气道时，麻醉师和外科医生应意识到常见的环切开术器械及其潜在的局限性。
