Invasive breathing with pros and cons
Invasive ventilators are prone to cause the occurrence of ventilator associated pneumonia (Ventilator associated pneumonia, abbreviated as: VAP).
Ventilator-associated pneumonia is a common complication of patients who use ventilator ventilation in the intensive care unit, and the incidence is as high as about 30%. Ventilator-associated pneumonia can cause difficulty in weaning, aggravate the patient's condition, prolong the hospital stay, and even lead to death of the patient in severe cases.
Current medical research believes that the causes of ventilator-associated pneumonia include the patient’s age, original underlying diseases, complications, and iatrogenic factors (improper operation and drug factors). The longer the ventilator ventilation time, the greater the incidence of VAP. high.
The main cause of VAP is bacteria that follow the pipe into the lower respiratory tract.
The pathogenic bacteria of early-onset VAP mainly include Streptococcus pneumoniae, Haemophilus influenzae and Staphylococcus aureus, all of which come from the parasitic flora of our oropharynx. Delayed VAP pathogens are mainly Gram-negative (G-) bacilli.
Bacteria are most afraid of antibiotics. The embarrassing thing is that long-term dependence on antibiotics will lead to the "evolution" of the flora. VAP pathogens not only have a generally high drug resistance rate, but are also "masters" with multiple drug resistance. Many commonly used antibiotics are not against them. kick in.
This is easy to fall into bad circulation, because the longer the ventilation time of the ventilator, the lower the defense function of the patient's airway, which is more likely to cause bacteria to multiply and increase the rate of lung infection.
Tracheotomy can also cause lower respiratory tract infections, complicated by airway stenosis and other problems.
