Respiratory depression is mainly caused by different degrees of restriction of the respiratory nerve center of the body, as well as the surrounding respiratory chemoreceptors are affected, and the respiratory center impulses of the receptors are inhibited, which manifests as shortness of breath, chest tightness, shortness of breath, and even respiratory distress, weakness, dizziness, and a continuous state of lethargy and coma. At this time, tracheotomy should be performed early, tracheal intubation should be given, mechanical ventilation and oxygen should be administered, and necessary respiratory central stimulants should be given to keep the vital signs stable. If the bronchial smooth muscle is in spasm and wheezing and shortness of breath are more obvious, glucocorticoids and bronchodilators can be given appropriately. In case of diffuse pulmonary bacterial infection, sensitive antibiotics such as cephalosporin III combined with quinolones should be chosen for anti-inflammatory treatment at this time.
