Background: Goal-oriented ultrasound examination is gaining a place in the intensive care unit. Some protocols have been proposed but the applicability of ultrasound as part of a routine has not been studied.
Objectives: To assess the influence of ultrasound performed by intensive care physicians.
Methods: This retrospective descriptive clinical study was performed in a medical-surgical intensive care unit of a university-affiliated general hospital. Data were collected from patients undergoing ultrasound examinations performed by a critical care physician from January 2010 to June 2011.
Results: A total of 299 ultrasound exams were performed in 113 mechanically ventilated patients (70 males, mean age 65 years). Exams included trans-cranial Doppler (n=24), neck evaluation before tracheostomy (n=15), chest exam (n=83), focused cardiac echocardiography (n=60), abdominal exam (n=41), and comprehensive screening at patient admission (n=30). Ultrasound was used to guide invasive procedures for vascular catheter insertion (n=42), pleural fluid drainage (n=24), and peritoneal fluid drainage (n=7). One pneumothorax was seen during central venous line insertion but no complications were observed after pleural or abdominal drainage. The ultrasound study provided good quality visualization in 86% (258 of 299 exams) and was a diagnostic tool that induced a change in treatment in 58% (132 of 226 exams).
Conclusions: Bedside ultrasound examinations performed by critical care physicians provide an important adjunct to diagnostic and therapeutic performance, improving quality of care and patient safety.
