Abstract
Aim: To make analysis of indications, duration, complications and outcome of the mechanical ventilation in patients treated in the Emergency Respiratory Ward.
Data and methods:
A retrospective analysis of the patients in the Emergency Respiratory Ward treated with mechanical ventilation during the last 5 years (2007-2011) has been made. 191 patients (10,33%) from the total number of patients (1848) needed mechanical ventilation.
Results:
The percentage of patients, treated with mechanical ventilation, does not differ substantially during the studied years – from 10,81% in 2007 to 11,68% in 2011.
The most common reason for heavy respiratory insufficiency, demanding mechanical ventilation, is pulmonary pathology (81,67%) as the greatest percentage belongs to COPD exacerbation and its complications (pneumonia) – 134 patients (85,90%). The most common reasons from the non-pulmonary pathology are alveolar hypoventilation in case of extreme obesity, chest deformations, left - side cardiac insufficiency.
The usual duration of mechanical ventilation is 15 days as there are no significant differences in the studied years – from 77,14 % to 87,10 %.
7 of the patients (3,66 %) have a verified diagnosis ventilator – associated pneumonia.
The total number of patients with lethal outcome is 66 (34,50 %) as there are no significant differences in the studied years.
Conclusion:
About 10 % of the patients, treated in Emergency Respiratory Ward, need mechanical ventilation as the most common pulmonary pathology is COPD. Problematic microbial flora, most often Gram /-/ strains are isolated in tube secrets, which significantly deteriorates the prognosis and leads to lethality in 34,50 % of the cases.
