Evolving strategies for ventilator management could reduce the frequency of complications, but there is limited information about complications in contemporary intensive care units.

We retrospectively collected information about patient demographics, chest x-ray abnormalities, complications, including pneumothoraces, ventilator-associated events, self-extubation, and resource utilization in 174 patients who required mechanical ventilation in 2013.

The mean age was 57.8 ± 16.8 years, the number of ventilator days was 7.5 ± 7, and the overall in-hospital mortality was 32.2%. The mean fluid balance per day during the mechanical ventilation period was 1539 ± 1721 mL. Three (1.7%) patients developed pneumothoraces, and 5 patients required chest tubes. Twenty-five (14.4%) patients had ventilator-associated events. Ten patients had episodes of self-extubation, and 11 had episodes of failed extubation. Chest X-rays showed new or increasing infiltrates in 113 (64.9%) patients and new or increasing pleural effusions in 29 (16.7%) patients. These patients had 1.2 ± 0.4 X-rays per day on the ventilator, and they had 10.0 ± 9.4 arterial blood gases and 0.7 ± 0.7 central lines.

The frequency of ventilator-associated complications was low in this study. However, these patients frequently developed increasing infiltrates, and these outcomes need attention during patient management and are a potential focus for future studies.
