Pneumonia: symptoms and treatment

Pneumonia refers to acute infectious diseases. The causative agents of pneumonia can be varieties of viruses, bacteria, fungi. There are also species such as aspiration pneumonia or para cannular pneumonia that develops around a nidus of cancer in the lung tissue. At the first signs of pneumonia, an urgent need to consult a doctor.

The inflammatory process in the lungs – a disease that can cause significant harm to health. Prior to the invention of antibiotics, mortality from pneumonia reached 80%. Currently, in various regions, death rates due to the development of pneumonia range from 5 to 40%, and the elderly are most affected.

The uncomplicated form of the disease with timely diagnosis and treatment can be cured in 10-14 days. Modern medicines help to avoid severe complications and cure almost any form of pneumonia without consequences. However, it must be remembered that for effective treatment and successful prevention of complications, a specialist should be engaged in the treatment of this disease.

Pneumonia: symptoms and treatment

What is pneumonia

Pneumonia is an inflammatory process with localization in the lung tissue. In most cases, the causative agent is an infectious agent. Ways of infection in the body are different, most often it is airborne, at least – spread through the bloodstream.

Part of the microorganisms responsible for the development of pneumonia is constantly present in the human body. With the proper level of immune protection, the body successfully copes with such infections, while reducing the level of protective forces (hypothermia, primary disease) develops an inflammatory process in the lungs.

Most often in the etiology of pneumonia, there are diseases of the upper respiratory tract. In this case, on the background of the symptoms of a cold, tracheitis, acute, chronic bronchitis, or another source of infection in the respiratory organs, an inflammatory process develops in the lungs. The onset of the disease can also be a consequence of the previous illness of other organs and systems, a complication after surgery, other situations that adversely affect the immune system.

Symptoms of pneumonia in adults and children

The symptomatology of the disease depends on the reasons that caused it, the patient’s age, and the state of his health. The disease is acute or develops in a worn form, may have classic symptoms or be asymptomatic, atypical pneumonia. The most severe course of the disease with severe pulmonary complications is observed in elderly patients, people with weakened immune systems and children with their imperfect immune system.

Pneumonia: symptoms and treatment

Symptoms in adults

The most frequent triggering factor of the inflammatory process in the lungs in the adult part of the population is hypothermia. The characteristic symptoms of pneumonia in such cases include the following manifestations that arise sequentially:

  • suddenly developing hyperthermia of the body, a sharp rise in temperature to febrile indices
  • symptoms of intoxication (fatigue, weakness, headaches )
  • for 3-5 days a dry cough appears, turning into a wet, with sputum
  • pain in the chest from the side of the lesion of the lung tissue (with bilateral pneumonia on both sides) when coughing and breathing. Sometimes wheezing is clearly heard
  • the appearance of shortness of breath as a result of extensive damage to the lung and the onset of respiratory failure.

The picture of the disease may not correspond to the classical pattern of the disease. The clinical manifestations and severity of the disease largely depend on the type of pathogen of the inflammatory process. Thus, among the atypical pathogens known is the H1N1 flu virus, the infectious agent of “swine flu”, which causes a serious complication in the form of viral bilateral pneumonia, accompanied by significant lesions of the lung tissue with extensive foci of inflammation, acute respiratory failure.

With a high frequency of pneumonia develops against the background of acute respiratory infections, SARS, accompanied by flu-like symptoms. The risk of pneumonia and the presence of other complications is significantly increased with an independent “treatment”, most often consisting of the administration of antipyretic drugs. This contributes to the spread of infection down the respiratory tract and the formation of infectious lesions in the lungs. Thus, the prevention of pneumonia in infectious diseases becomes the full course of treatment and timely diagnosis.

Symptoms in children

The incidence rate in children correlates with age: babies up to three years old suffer 2-3 times more often (1.5-2 cases per 100 people) than children older than 3. Infants suffer from pneumonia more often due to aspiration of gastric contents during regurgitation, ingestion of foreign tel in the respiratory tract, birth trauma, malformations.

The symptoms of pneumonia in childhood also vary depending on the age, etiology, and distribution of the inflammatory process.

At the age of one year, there are the following signs:

  • drowsiness, lethargy, general malaise, lack of appetite
  • irritability, frequent causeless crying
  • hyperthermia, often in sub febrile limits
  • the increased rhythm of breathing
  • in a unilateral process, signs of insufficient filling of one of the lungs, lagging of half of the chest during respiratory movements;
  • symptoms of respiratory failure – cyanosis of the nasolabial triangle, fingertips, especially during crying, feeding, increased excitement.

In older children with pneumonia, the symptoms are similar to manifestations of pneumonia in adults: fever, weakness, drowsiness, increased sweating, loss of appetite, loss of interest in hobbies, pronounced general indisposition, respiratory failure may develop with inflammatory process in large areas of the lungs or individual characteristics of the child.

Pneumonia: symptoms and treatment

Pneumonia classification

The classification of pneumonia as a well-studied disease is based on several factors, which makes it possible to more accurately diagnose and more effectively treat pneumonia in patients.

Categorization by condition

Outpatient pneumonia and nosocomial, nosocomial pneumonia are distinguished. A form that develops in a hospital, clinic 48 hours after the patient is hospitalized for other reasons is considered to be nosocomial. This type of pneumonia is distinguished due to the characteristics of the course and treatment, as in the conditions of hospitals and hospitals often develop strains of infectious pathogens that are resistant to antibacterial therapy.

Aspiration form, which develops as a result of ingress into the lower respiratory tract of the contents of the oral cavity, nasopharynx or stomach, as well as foreign particles in the form of solids. Bacterial pathogens that are in aspiration masses or objects develop and cause severe inflammation with purulent complications: the development of purulent sputum, difficulty in transporting it and significant damage to lung tissue

Lung volume classification

Depending on the prevalence of the inflammatory process, the volume of lung tissue involved, there are several types of disease.

Symptoms of focal pneumonia

The focal form is characterized by a clear localization of the inflammatory process. Most often, this species develops as a complication of a viral disease. There is a dry cough with the transition to a wet form, high body temperature, pain when coughing, the presence of sputum with purulent patches.

The unilateral form of the disease

The process captures only the right or left lung, and can extend to a small segment or involve all lobes of the organ. Symptomatology depends on the extent of the lesion, the pathogen, the general condition of the patient, may be pronounced or asymptomatic.

Bilateral pneumonia

Localization of foci of inflammation is noted in both the right and left lung. In this case, the inflammatory process may be segmental, lobar, or involve the entire body. The main difference is that both sides of the lung are affected, regardless of the extent of the lesion.

Croupous pneumonia

In this form, characterized by one of the most pronounced clinical pictures. Distinct external symptoms of the lobar form are a sharp increase in body temperature to the limit values (40 ° C and above), a pronounced pain syndrome, a characteristic yellow-orange shade of discharge of sputum.

The causative agent of lobar pneumonia most often becomes pneumococci, and the timely prescription of antibacterial drugs (most often prescribed antibiotics of the penicillin series) brings recovery in both croupous and other forms of pneumococcal pneumonia.

Lobar inflammation

The lung is an organ consisting of conditional lobes: in the right lung, there are three, in the left – two. If one organ lobe is affected, then it is a lobar form, localization in two lobes means a bilobal form, unilateral or bilateral. With the defeat of the two lobes of the left lung talk about total pneumonia, two lobes of the right – subtotal form.

Types of inflammation characterize the vastness of the process and the severity of tissue damage. The more segments and shares involved, the more pronounced the symptoms of the disease.

Classification of pneumonia due to illness

Diagnosis of the disease by pathogen largely dictates the methods of therapy and the choice of drugs. Depending on the causes and type of infectious agent, there are several types of disease

Inflammation of the lungs of viral etiology

Infectious pneumonia caused by viruses may be a complication of influenza, parainfluenza or ARVI (adenoviral form) or have a primary etiology. In view of the imperfection of diagnostic methods, it is not always possible to identify which virus is responsible for the occurrence of the disease, therefore, treatment is most often carried out with the use of broad-spectrum antiviral drugs and is symptomatic.

If antibacterial agents are prescribed for the viral form, this means that there are symptoms or the likelihood of bacterial infection.

Bacterial infections in the etiology of pneumonia

Bacterial pneumonia is one of the most common types. There are several groups of bacteria that can cause inflammatory processes in the lower respiratory tract. Among them, the most common causative agent of pneumonia is pneumococci, streptococci, staphylococci, mycoplasma, chlamydia, pyocyanin stick, and others.
If the pathogen is correctly identified and the effective drug is selected, the bacterial form is successfully treated with antibiotics. However, it is important to remember that it is necessary to select a therapy based on the sensitivity of the bacterium to the drugs of a particular group.

Features staphylococcal pneumonia

The staphylococcal form is most often a complication after ARVI. The disease is characterized by symptoms of significant body intoxication, the scarlet color of discharge of sputum, weakness, dizziness.

The causative agent of mycoplasma pneumonia

Mycoplasma form develops when specific bacteria, mycoplasmas, enter the lung tissue. Most often this form of the disease affects children and adolescents.
The disease is not distinguished by severe symptoms, which makes diagnosis difficult, is treated successfully, although the treatment process itself is rather long due to the peculiarities of mycoplasma as a pathogen.

Chlamydial infection in the etiology of pneumonia

The cause of the development of chlamydial pneumonia is exposure to the respiratory tract and lungs of chlamydia, bacteria that normally cause bacterial chlamydia of the vagina. The most common route of infection from mother to child when passing through the birth canal, if there was no prenatal reorganization of the vagina and there is a harmful flora containing chlamydia.

This type is more common among children, especially infants, and adolescents, and at the initial stage has an unexpressed clinical picture similar to acute respiratory infections. Therapy in this form of the disease is selected individually, taking into account the age and characteristics of the patient.
Together with mycoplasma infections, these two forms fall under the category of atypical pneumonia, also characterized by lesions of the alveoli and interstitial tissues. The nature of interstitial pneumonia is often protracted, with a transition to the chronic form.

Fungal infections

Various fungal pathogens can also cause an inflammatory process in the lungs. At the same time, the diagnosis requires a thorough examination, since the clinical picture is not expressed, the symptoms for a long time can be quite “blurred” and do not correspond to the classic manifestations of the disease of bacterial etiology. Long-term treatment with the use of antimycotic drugs.

Any types and stages of pneumonia are considered a serious disease, dangerous complications and negatively affecting the organism as a whole. The course of correctly selected therapy allows curing patients with high efficiency, provided that they are treated promptly for diagnosis and in compliance with the specialist’s prescriptions
