Laryngeal obstruction is a disease caused by a lesion in the larynx and surrounding adjacent tissues of the body, which usually manifests as difficulty in inspiration and breathing. Laryngeal obstruction is usually caused by acute inflammation of the larynx, or by traumatic injury and the presence of tumors and foreign bodies, etc. If the patient has a congenital malformation or scar stenosis, laryngeal obstruction is also easily triggered. Patients with laryngeal obstruction usually suffer from dyspnea, laryngeal sounds when breathing, lack of oxygen in the face, rapid pulse, and irritability. If the symptoms of laryngeal obstruction occur in elderly and frail patients, they should be treated promptly because they are less tolerant and can easily have difficulty breathing, leading to the occurrence of asphyxia. When laryngeal obstruction occurs, foreign bodies in the respiratory tract should be removed in a timely manner. If respiratory distress occurs, tracheotomy should be taken immediately to improve respiration, and it is recommended to adopt a semi-recumbent or flat position, and patients are advised to rest in bed to reduce exercise and oxygen consumption. When laryngeal obstruction develops, it should be treated promptly by closely monitoring respiratory changes, quickly establishing intravenous access to the patient, and keeping the airway open.
