What are the main manifestations of severe pneumonia?

summary

The severity of pneumonia depends on the degree of local inflammation, the spread of pulmonary inflammation and systemic inflammatory reaction. Severe pneumonia can be identified as severe pneumonia if severe hypoxemia or acute respiratory failure occurs in patients with pneumonia, requiring ventilation support, or circulatory failure such as hypotension and shock and other organ dysfunction. What are the main manifestations of severe pneumonia? Let's talk about it

What are the main manifestations of severe pneumonia?

Severe pneumonia will have the performance of respiratory failure, nervous system symptoms mainly include mental depression, drowsiness or irritability, severe cases can appear disturbance of consciousness, optic disc edema, coma, convulsion, and then cerebral hernia, children can die due to central respiratory failure.

Severe pneumonia can often lead to circulatory system involvement, such as weak pulse, faster heart rate, low heart sound, cyanosis, lung rales and so on. When shock and circulatory failure occur, pale complexion, dark and cold skin, decreased urine volume, decreased blood pressure and prolonged capillary filling time will appear.

Blood routine examination showed that the total number of white blood cells could be increased or not, but more than half of them showed left shift of nucleus, increase of C-reactive protein and acceleration of erythrocyte sedimentation rate (ESR). When PaO2 < 8.0 kPa (60 mmHg) and PaO2 / FiO2 < 39.90 kPa (300 mmHg), mechanical ventilation was needed.

matters needing attention

In case of high fever, stay in bed, reduce oxygen consumption, use physical cooling, or use drugs to cool down as required by the doctor, supplement water and salt lost due to fever by vein, and monitor and record the change of body temperature. Encourage patients to breathe deeply, help them turn over and make chest percussion, guide effective coughing and promote expectoration. When sputum is sticky and difficult to cough up, patients can be encouraged to drink more water, and atomization inhalation can also be given.
