A wet cough is a cough that produces mucus or mucopurulent sputum. The symptom develops against the background of pain in the chest (thoracalgia), wheezing, signs of general intoxication of the body. This type of cough is observed in bronchitis and other bronchopulmonary pathologies, respiratory infections, heart failure. To determine the root cause of the disorder, x-rays, spirography, bronchoscopy, and laboratory tests are performed. In order to reduce discomfort, inhalations, the use of mucolytics, expectorants, and anti-inflammatory drugs are prescribed.
Sputum secreted after a cough attack is usually represented by a mucous secretion, which is formed when the lower respiratory tract (trachea, bronchi, bronchioles) is affected. With the development of inflammation, the production and removal of mucus is enhanced to clear the respiratory system of pathogens or foreign particles. In turn, the mucus stimulates the nerve endings, causing coughing. After the discharge of a wet secret (mucus or pus), the state of health improves somewhat.
In acute forms of bronchitis, the cough is initially dry. Sputum begins to depart on the 2nd-3rd day of the disease, while the condition improves markedly, pain in the chest area subsides. A specific productive cough is characteristic of such types of bronchial inflammation as:
With the outcome of chronic purulent bronchitis in bronchiectasis, coughing attacks become permanent, and purulent sputum becomes fetid and profuse (up to several hundred milliliters per day). It is especially abundant in the morning (expectoration with a "full mouth") or after being in the so-called drainage position (lying on the affected side with the head end of the bed lowered). With a high intensity of wet cough, the blood vessels of the thinned walls of the bronchi rupture, which leads to hemoptysis, and in severe cases, to pulmonary hemorrhages.
The discharge of a small amount of moist, odorless, mucus-like secret indicates the completion of an asthma attack. The sputum is usually colorless. A possible yellowish or greenish tint of mucus is due to the breakdown of eosinophils, bronchial epithelium, and other cells, less often - the presence of pus during secondary infection of the bronchi. After coughing up sputum, the patient's condition gradually improves: the rhythm of breathing is restored, suffocation disappears. During an asthma attack, very viscous mucus can also be difficult to expectorate.
With inflammation of the lungs of any etiology, the cough becomes wet only on the 3rd-4th day of the disease. The nature of the secret depends on the type of pathology: with viral pneumonia and mycoplasmal respiratory infection, patients note the release of a small amount of transparent viscous mucus without pus or blood, bacterial focal pneumonia is characterized by purulent discharge. With croupous inflammation of the lungs during a wet cough, “rusty” sputum containing blood inclusions leaves.
Pneumonia begins acutely with severe thoracic pain, tremendous chills, shortness of breath, which is accompanied by a cough. In an uncomplicated course, the temperature reaches 38-38.5 ° C, in case of damage to an entire lobe of the lung, the patient is worried about high fever, chills. The duration of a wet cough for more than 3 months indicates the chronic nature of the inflammation, which is typical for people with immunodeficiencies. In children, chronic recurrent pneumonia may be a sign of congenital lung hypoplasia.
Complaints about a productive cough occur in diseases of the lower respiratory system, both inflammatory and non-inflammatory. Increased production of wet mucous secretion provokes the influence of parasites, the deposition of pigment compounds in the lungs with congenital or acquired metabolic disorders of trace elements. The intensity and frequency of attacks depend on the severity and duration of the disease. Coughing up a secret is typical for the following types of pulmonary pathology:
In most cases, these diseases are characterized by the absence of sputum. However, the appearance of a wet cough is possible at the stage of recovery or with certain clinical variants of laryngotracheitis occurring with damage to the glandular cells of the mucous membrane. When the process is localized in the larynx and trachea, patients notice a change in voice - it becomes low and hoarse, it constantly tickles or “scratches” in the throat, and pain is disturbing when swallowing. With the separation of the secret after a cough paroxysm proceed:
The disease often develops as a complication of acute heart failure, cardiac asthma, but can complicate the course of severe diseases of the respiratory, urinary systems, and other internal organs. A few hours before the manifestation, tightness or pain in the chest is felt, shortness of breath increases. Then there is a painful cough and suffocation, which makes the patient rise in bed to facilitate breathing. A cough attack is accompanied by the release of foamy pink sputum, wheezing, blue nasolabial triangle.
Tumors of the lung are usually asymptomatic or asymptomatic. Severe clinical symptoms are observed only in 10-15% of cases, mainly with the central localization of a malignant neoplasm. With all types of oncological pathology, the first manifestations are non-specific symptoms of intoxication - causeless weakness, weight loss, loss of appetite, and only then cough. With expectoration of sputum can occur:
A prolonged productive cough is a reason to contact a pulmonologist who will select the optimal diagnostic plan depending on the general condition and the presence of other complaints. To identify the cause of the symptom, a comprehensive assessment of the morphological and functional features of the respiratory system is carried out. The most diagnostic value are:
For differential diagnosis between inflammatory and other pathologies of the respiratory system, a general blood test is performed, and the concentration of acute phase proteins is determined. If the infectious nature of a wet cough is suspected, serological tests are prescribed to determine antibodies to pathogenic microorganisms. To clarify the structure of volumetric formations of the chest cavity, tomography (CT, MRI) is performed. Informative examination of the ENT organs: pharyngoscopy, laryngoscopy.
Expectorants and mucolytics are effective for wet coughs
To reduce the frequency of wet cough attacks, sudden changes in temperature should be avoided, if possible, contact with household chemicals and other irritants should be limited. Regular inhalations with antiseptics and anti-inflammatory drugs help reduce pain, stimulate mucus discharge. With viscous and thick sputum, expectorants and mucolytics are effective, which help to clear the bronchial tree from mucus.
It is forbidden to use specific antitussive drugs, as they cause a delay in the mucous secretion and pathogens in the respiratory tract, which prolongs the recovery period. An increase in the volume or a change in the nature of the secret, frequent coughing attacks leading to insomnia are indications for a visit to the doctor, who will find out the cause of the wet cough and prescribe etiotropic treatment. With the development of hemoptysis, the appearance of pink foamy sputum, emergency medical care is required.
