Nosocomial Pneumonia (NP) is an infection of lung parenchyma that could
happen at least 48 hours after admission in hospital. After urinary tract infection, it is the second
most common nosocomial infection and is most common in Intensive Care Units (ICU).
Incidence of NP in ICU is about 10-20%.
Materials and Methods: 402 patients evaluated in Emdad and Fatemieh hospitals. Variables
were age, gender, depressed level of consciousness, mechanical ventilation, nasogastric tube,
thoracoabdominal surgery and medical or surgical ICU patients visited daily. Criteria of NP
were fever after 48 hours, leukocytes, increase in pulmonary secretion and chest X-ray
findings. Logistic Regression was used for analysis data.
Results: 9.2% (CI 95%; 6.4-12.0%) of patients developed NP. In patients with mechanical
ventilation and depressed level of consciousness, incidence was 7.6 times and 2.7 times more
than others, respectively. There was no relationship between NP and other variables.
Conclusion: Mechanical ventilation and unconsciousness are important risk factors for NP.
Thus, these patients require more and better cares. Furthermore, intervention should be avoided
if patients require mechanical ventilation meticulous aseptic care for respirator equipments and
suctioning is needed.
