Emergent use of tube tip in pharynx technique in “cannot intubate cannot oxygenate” situation: A case report

BACKGROUND: A “cannot intubate, cannot oxygenate (CICO)” situation is a life-threatening condition that requires emergent management to establish a route for oxygenation to prevent oxygen desaturation.

Sumario:BACKGROUND: A “cannot intubate, cannot oxygenate (CICO)” situation is a life-threatening condition that requires emergent management to establish a route for oxygenation to prevent oxygen desaturation. In this paper, we describe airway management in a patient with an extended parotid tumor that invaded the airways during CICO using the endotracheal tube tip in the pharynx (TTIP) technique. CASE SUMMARY: A 43-year-old man was diagnosed with parotid tumor for > 10 years. Computed tomography and nasopharyngeal fiberoptic examination revealed a substantial mass from the right parotid region with a deep extension through the lateral pharyngeal region to the retropharyngeal region and obliteration of the nasopharynx to the oropharynx. Tumor excision was arranged. However, we encountered CICO during anesthesia induction. An endotracheal tube was used as an emergency supraglottic airway device (TTIP) to ventilate the patient in a CICO situation where other tools such as laryngeal mask airway or mask ventilation were not suitable for this complicated and difficult airway. The patient did not experience desaturation despite sudden loss of definite airway. During tracheostomy, the pulse oximetry remained 100% with our technique of ventilating the patient. The arterial blood gas analysis revealed PaCO(2 )35.7 mmHg and PaO(2) 242.5 mmHg upon 50% oxygenation afterward. CONCLUSION: Using an endotracheal tube as a supraglottic airway device, patients may have increased survival without experiencing life-threatening desaturation.
