As experts of the human airway, it is our job as anaesthesiologists to control and secure the airway in the safest way possible for the patient. The perioperative anaesthetic plan always includes an airway component, ranging from bag-mask ventilation to endotracheal intubation. Routine surgical procedures may warrant a certain standardised airway strategy that may vary among institutions. However, there exist situations that are less common, in which standard airway practice is unclear. If the injury is suspected to be in a highly sensitive area and securing an airway may compromise or cause further injury, radiographic imaging may be warranted.1
Figure 1 depicts a paediatric patient impaled in the soft palate of the left oropharynx by a freezer pop stick that the patient had been previously enjoying and accidentally fell onto. (left of image). The CT scan portion of the figure is a contrast CT scan of the head and neck, in which the tract of the freezer pop stick is visualised. The most notable aspect is that the proximal (to the patient) end of the freezer pop stick lies only 2 mm anterior to the left external carotid artery. The main concern being that manipulation and securing of the airway could cause a shift of the foreign object with catastrophic results.2 3 Given this clinical context, the imaging study proved to help shape and plan our anaesthetic technique.
After extensive discussion and preparation with the ENT surgeon, the patient was induced via mask general anaesthesia and kept spontaneously ventilating. We were able to successfully secure the airway with an endotracheal tube with direct laryngoscopy using a video laryngoscope in the midline position of the airway (no sweeping of the tongue). This technique allowed us to simultaneously visualise the freezer pop stick and glottic opening, while avoiding any movement of the foreign body during intubation. The ENT surgeon was able to remove the freezer pop stick without any adverse events.
Prior to a general anaesthetic, consider use of advanced imaging modalities in specific trauma situations in order to best plan airway interventions.
Time permitting, proper discussion with the surgical team prior to induction and intubation is warranted with secondary and tertiary options readily available if unable to gain airway control in patients where a foreign body may interfere.
