1 Laryngeal obstruction
Causes: Infection Tumors Foreign bodies Trauma Allergy Malformation Laryngeal paralysis

2 Laryngeal obstruction
symptoms: inspiratory dyspnea inspiratory stridor depression of suprasternal fossa, intercostal and supraclavicular space or epigastrium while inspiration hoarseness and even cyanosis


4 Laryngeal obstruction
classification: Ⅰ°there is no symptoms at rest. But slight inspiratory dyspnea and stridor may occur during crying or on exertion

5 Laryngeal obstruction
classification: Ⅱ°slight inspiratory dyspnea during quiet respiration, and exaggeration on exertion. Sleeping and taking the meal is nearly normal , no evidence of hypoxia.

6 Laryngeal obstruction
classification: Ⅲ°:with marked inspiratory dyspnea, loud stridor, depression of suprasternal and supraclavicular fossae and intercostal spaces, cyanosis, restless and struggles for air hunger, with quick pulse, high blood pressure and refuse meals.

7 Laryngeal obstruction
classification: Ⅳ°:extremely dyspneic, restless, sweating, cyanoticsis. Pulse is rapid, irregular, weak and thready. B.P. drops. Finally circulatory collapse may occur or may die of asphyxia or cardiac failure.

8 Laryngeal obstruction
Treatment Ⅰ°:etiological treatment, antibiotics and corticosteroid.

9 Laryngeal obstruction
Treatment Ⅱ°:etiological treatment . in case of tumors of the larynx, trauma, bilateral vocal cords paralysis, tracheotomy is indicated.

10 Laryngeal obstruction
Treatment Ⅲ°:If the laryngeal obstruction is caused by inflammation, medical treatment can be administrated under close observation. Tracheotomy should be prepared. If dyspnea is not relieved, tracheotomy should be performed immediately.

11 Laryngeal obstruction
Treatment Ⅳ°:Tracheotomy

12 Tracheotomy Tracheotomy is a surgical procedure in which an opening is made in the anterior wall of the trachea to establish an airway.

13 Tracheotomy Tracheotomy is often temporary and reversible if the patient is able to breathe through an unobstructed upper airway

14 Tracheotomy Anatomy:2nd-4th ring of trachea Indication:
Laryngeal obstruction Secretion obstructed in lower respiratory tract (coma) Before some major head & neck surgery






20 Tracheotomy Complications Hemorrhage Subcutaneous emphysema
Pneumothorax Difficulty of decannulation Laryngeal or tracheal stenosis

21 Cricothyrotomy Employed in first-aid cases.
Making an opening in the membrane between the cricoid cartilage and thyroid cartilage and insert a cannula. After the situation becomes stable, ordinary tracheotomy should be performed.
