Prevention of ventilator associated pneumonia is not an effective approach to the prevention of vent

It is not an effective method for the prevention of pneumonia associated with respiratory ventilation ()aReduces oropharyngeal and upper gastrointestinal colonization.

b.Protects the properties of the gastric mucosa.

c.Reduce exogenous pollution.

d.Use a PICC catheter.

Zheng Zheng Ji implicitly answered: d

Answer]: e Prevention of lower respiratory tract infection, especially the prevention and care of ventilator-associated pneumonia (the incidence of VAP is 18% to 60%, **difficult, the case fatality rate is as high as 30% 60%). The use of subglotine drainage (SSD) is an effective and simple method to prevent VAP, but a comprehensive approach is more important.

For example, sterile water is used for the humidifier of the ventilator, which is replaced every day; Prevent condensate from backflowing, dump and wash hands in a timely manner; Pipes are replaced regularly; Do a good job of airway collapse care and effective sputum suction, back patting, etc.

Answer] :d sterile water for the humidifier of the ventilator, replace it every day; Prevent condensate from backflowing, dump and wash hands in a timely manner; Pipes are regularly replaced with more sensitivity; Do a good job of gas medicine and effective sputum suction, back patting, etc.

This question is aimed at the "prevention and care of common nosocomial infections" with knowledge points

Aspiration pneumonia is pneumonia caused by inhalation of amniotic fluid or meconium. If the fetus is deprived of oxygen during utero or delivery, it will breathe and move to inhale amniotic fluid or amniotic fluid with meconium. Term and postterm infants are more likely to have this condition.

Generally, symptoms such as shortness of breath and bruising are present immediately after birth, and vesicles can be heard on auscultation of the lungs. Meconium aspiration patients are more likely to be complicated by pneumothorax. Mild disease can reduce symptoms within 1 to 2 days, and severe disease can lead to respiratory failure.

Avoidance of intrauterine hypoxia is key to prevention, and if amniotic fluid or meconium aspiration is present, the inhalation should be aspirated as much as possible at the time of delivery.

The main risk factors associated with VAP are: Older age, poor self-condition People with chronic lung disease, long-term bed rest, loss of consciousness Coughing up phlegm is not easy to cough up Mechanical ventilation for a long time, antibiotics have been used before getting on the machine, especially broad-spectrum antibiotics cause dysbiosis Bacterial translocation in the digestive tract, long-term use of H receptor blockers and proton pump inhibitors, gastric acid deficiency is easy for bacteria to parasitize in the digestive tract. Among them, long duration of mechanical ventilation was the main risk factor for the occurrence of nosocomial pneumonia, and the risk of nosocomial pneumonia in patients with continuous mechanical ventilation was 6 12 times higher than that in those without mechanical ventilation. Recent studies have also identified hypotension as an independent risk factor for the prognosis of VAP.
