Blunt Abdominal Trauma, FAST, Serum Therapy, Hydration


Background: Trauma is the first cause of youth mortality in developing countries. Focused Assessment Sonography for Trauma (FAST) is a reliable tool for examining trauma patients. Hence, the purpose of this study was to compare the FAST findings before and after serum therapy.

Materials and Methods: This descriptive-analytical study was performed on 200 trauma patients, who randomly entered the study. Inclusion criteria were the patients with suspected and normal cases in FAST results, and stable vital signs and exclusion criteria were positive FAST findings, penetrating abdominal trauma, and unstable vital signs. The trauma patients underwent sonography at the baseline and four hours after serum therapy. Data were analyzed using descriptive (mean and percentage) and inferential (Wilcoxon) statistics.

Results: The mean age of patients participating in the study group was 33.47±15.85 years, including 86.5% male and 13.5% female. The results showed that serum therapy could significantly increase oxygen saturation, diastolic blood pressure, and level of consciousness (P=0.001). Respiratory rate, pulse rate, and systolic blood pressure were reduced, and the number of FAST-based suspicious diagnoses was also decreased (P=0.001).

Conclusion: Our study demonstrated that serum therapy reduces suspected cases in the FAST examination.
