A voice box cough is generally defined as a cough with a rumbling sound. Colds generally do not cause cough with rales, such as complications resulting in acute tracheobronchitis can cause rales, the need to use drugs to treat. Colds are virus-induced upper respiratory tract infections that cause congestion and edema of the mucous membranes of the nose, throat and larynx, resulting in symptoms such as runny nose, nasal congestion, cough, sore throat, etc., but generally do not produce rales. If there is acute tracheo-bronchitis complication of cold, tracheo-bronchial mucosal edema, excessive mucus secretion, bronchospasm, etc. can lead to cough with rales. In patients with colds combined with bronchitis, if the sputum is too much and not easy to cough out, use ambroxol, bromhexine to resolve sputum, and if necessary, can be given acetylcysteine nebulization to dispel sputum. If bronchospasm leads to croup, asthma-relieving drugs such as theophylline aminophylline and β₂ agonist salbutamol can be used to relieve the symptoms. Cough with rales can also be caused by other diseases, such as bronchial asthma. If the symptoms do not improve or worsen, it is recommended to consult a doctor in time to clarify the cause of the disease, and under the guidance of the doctor reasonable treatment, so as not to delay the condition.
