A laryngeal foreign body is a foreign body that is lodged in the laryngeal cavity, and a larger foreign body that cannot pass through the vocal folds into the trachea and becomes embedded in the vocal folds. Common causes include sharp foreign bodies such as needles, bone fragments, metal pieces across the vocal folds, and larger foreign bodies such as peanuts, fava beans, and small toy parts. Most of them have a history of choking on foreign objects, such as crying, laughing, playing after containing objects in the mouth, and suddenly coughing violently, resulting in accidental laryngeal cavity embedded in the vocal folds. The main symptoms are hoarseness, severe cough, pain, laryngeal wheezing; larger foreign objects can lead to dyspnea, cyanosis, or even suffocation. Laryngeal examination can be seen on the vocal folds, vocal folds or vocal folds under the foreign body. Treatment: (1) Rescue of asphyxia: in case of obvious respiratory distress, emergency tracheotomy should be performed first, and after respiration is slightly slowed down, a larger foreign body in the subvocal or vocal area should be taken out upward from the tracheotomy. (2) remove the foreign body as soon as possible: ① indirect laryngoscopy to take the foreign body: a small number of adult patients with foreign bodies located in the supraglottic area can be used to 1% dicaine local mucosal surface anesthesia, in the indirect laryngoscopy with a laryngeal forceps to remove the foreign body. ② foreign body removal under direct laryngoscopy: according to the location and shape of the foreign body, use the appropriate laryngeal forceps to hold the foreign body, adjust the appropriate orientation, so that it can be removed smoothly. (iii) Extracervical incision to remove foreign body: only used in a few special cases, with respiratory distress, need to first tracheotomy, to be relieved after the respiratory distress from the tracheotomy to remove the foreign body. (3) Prevent infection and reduce the occurrence of laryngeal edema: appropriate antibiotics and steroids can be given before and after removing the foreign body. Available vancomycin V5.0g combined with dexamethasone 5~10 mg added to 5% glucose injection intravenous drip, or with gentamicin 80,000 units combined with dexamethasone 2mg ultrasonic nebulizer inhalation to anti-inflammatory swelling, improve the local symptoms.
