The Effect of the Emergency Physicians' Clinical Decision of Targeted Ultrasonography Application in Non-Traumatic Shock Patients

Abstract

Introduction Clinical evaluation of non-traumatic shock patients with high risk of mortality and morbidity is problematic for emergency physicians. In this study, changes in the investigations, diagnosis and treatment decision of the physicians using the Abdominal and Cardiac Evaluation with Sonography in Shock (ACES) protocol were examined. Methods In this clinical prospective study, the patients were ultrasonographically examined within the scope of the ACES protocol at 6 quadrants including cardiac, pleural, peritoneal, inferior vena cava and aorta. Pre- and post-US investigations, diagnoses and treatments were compared. Results A total of 141 patients were included in this study. Of these, 92 (65.2%) of the patients were males and 49 (34.8%) were females. The average age of the patients was 62.9±16.8 years (18-97). After the ultrasonographic evaluation, request for new investigations was needed in 25 (17%), and modification of the treatment was needed in 57 (40.4%) of the patients. It was seen that with a targeted ultrasonography (US), the number of the considered pre-diagnoses decreased in 51 (36.2%) of the patients, and the physicians made a new pre-diagnosis in 6 (4.3%) of the patients. When the pre-diagnoses made by the physicians after the US and the final diagnoses clinically made at the end of the follow-up process were compared, there were no changes in the diagnoses in 124 (87.9%) patients. Conclusion Ultrasonographic examination is considered useful for rapid evaluation, early diagnosis and treatment planning in non-traumatic shock patients in emergency department.
