Emergency Management and Nursing Considerations of Carotid Blowout Syndrome.

Introduction: Carotid blowout syndrome is a rare but fatal complication often witnessed secondary to treating patients with head and neck cancer. It occurs when damage and necrosis lead to the carotid artery wall rupture. The symptoms encountered in these patients range from asymptomatic to cardiac arrest. Here, we present 5 cases of carotid blowout syndrome in the emergency department.

Case presentations: Patients demonstrated symptoms ranging from subtle bleeding to hemodynamic instability, highlighting the diverse nature of carotid blowout syndrome in this population. Notably, while all patients had a history of radiotherapy, some had additional risk factors for carotid blowout syndrome, including prior surgery (n = 2), malnutrition (n = 3), and tracheostomies (n = 2). Definitive diagnoses were established through clinical evaluation and computed tomography angiography. Immediate interventions included bleeding control, resuscitation, and consultations with relevant specialties. Four patients underwent interventional radiology procedures, and 1 patient received otolaryngology care. While 2 patients recovered completely, 1 died in the emergency department, and 1 in the intensive care unit. One patient's clinical course was complicated by a stroke.

Conclusion: The approach to the carotid blowout syndrome patient includes complex steps that proceed in a multidisciplinary manner, starting from triage until discharge. Emergency nurses play crucial roles at every stage. They should be aware of carotid blowout syndrome when evaluating patients with head and neck cancer presenting with bleeding. When treating these patients, emergency nurses should be ready for airway interventions, bleeding control, and massive transfusion protocol. In this context, the multifaceted approaches made by nurses contribute significantly to carotid blowout syndrome management in the emergency department.
