Respiratory Distress Syndrome and Complicated by Ventilator Associated Pneumonia from
Prolonged Ventilation

Introduction:
65% of patients in Intensive Care Units (ICU) with severe sepsis and/or severe
traumatic lung contusion are complicated with pneumonia and respiratory failure, which
need long-term ventilation. Sepsis is a common finding in such patients; it is either a
cause of ventilator associated pneumonia (VAP) or a complication of VAP. VAP is one of
the most common complications of prolonged ventilation. Both diagnostic and therapeutic
bronchoscopies could be used to improve the outcome in those patients by controlling
septic reactions and improve lung mechanics through the clearing of the small airways
from purulent discharge.

Aims of Work:
To evaluate the effect of the use of bronchoscopy in patients with Acute respiratory
distress syndrome (ARDS), severe sepsis and complicated by VAP as regards, improve the
general condition of those patients, improve lung mechanics, control all signs of both
VAP and sepsis, accelerate weaning from the ventilator, shorten the duration of ICU
stays and its effect on mortality rate in those patients.

Materials and Methods:
200 patients were selected after 4 days of ventilation because of ARDS due to either
severe traumatic lung contusion or a severe lung infection. Those who still showed
unresolved ARDS (diagnosed by hypoxic index less than 200, bilateral parenchymatous lung
infiltration on the chest X ray, ABG showed PH > 7.30), Severe sepsis diagnosed by
>12 SOFA score (Sequential Organ Failure Assessment) and developed VAP diagnosed by
>6 CPIS score (clinical pulmonary infection score) were included in two groups of 100
patients in each. Only patients of group B did three bronchoscopies and BAL was sent for
culture, while patients of group A continued on the traditional way of management and
sputum was sent for culture. Improvement of ARDS & VAP, weaning from ventilation,
duration of ICU stay, improvement of one/all parameters of both SOFA & CPIS scores,
morbidity, and mortality were recorded and compared within 14 days.

Results:
Patients of group B showed significant improvement in APACHII score (acute
physiological assessment and chronic health evaluation score), GCS (Glasgow coma scale),
parameters of both SOFA score and CPIS score, hemodynamics parameters, LDH (lactate
dehydrogenase), and C-Reactive protein levels. A significantly higher number of patients
were weaned from the ventilator and discharged from ICU. There was no significant
difference between the two groups regarding the mortality rate.

Conclusion:
The use of bronchoscopy can improve general conditions, control all signs of severe
sepsis, VAP, improve lung mechanics, improve ARDS, accelerate weaning from the
ventilator, and shorten the ICU stay but has no effect on mortality rate in those
patients with severe sepsis with ARDS and complicated by VAP from prolonged ventilation.
