Neumonía nosocomial asociada a la ventilación mecánica en paciente masculino de 68 años de edad.

Nosocomial infections are infections that adhere during hospitalization and were not present or incubated at the time of admission to the institution. Infections that their incubation period may have been asymptomatic at the time of admission are excluded, plus 90% of pneumonia acquired in the Intensive Care Unit appears during mechanical ventilation 50% of pneumonia associated with the ventilator appears in the First four days after intubation. (VASQUEZ, 2017). At present it is known that in-hospital pneumonia has two foci of reservoir in the organism: The oropharyngeal cavity and the gastric cavity in both reservoirs change the saprophytic commensal flora due to potentially pathogenic microorganisms that do not usually exist in these areas of the organism. Microaspiration or macroaspiration of oropharyngeal or gastric contents to the airways would be the definitive mechanism that would cause nosocomial pneumonia provided that specific or nonspecific lung defenses were altered. The endotracheal tube also eliminates the most effective natural defenses of the upper respiratory tract. The mucociliary filtration and clearance system of the upper respiratory system is removed during intubation. Cases of pneumonia associated with the ventilator that appear in the 4 days following intubation are associated with a greater probability caused by microorganisms that have been dragged into the airways during the intubation procedure.
