Investigation of the changes in CT scan findings in patients with head trauma referred to the emergency department of Shahid Bahonar Hospital in Kerman in 2020

Background and Objectives: Investigating the changes in CT scans of patients is one of the most important methods to determine the prognosis of patients with head trauma, which has been considered by researchers. The aim of this study was to determine the findings of delayed CT scan in blunt head trauma patients referred to Shahid Bahonar Hospital of Kerman in 2020. Methods: This was a descriptive-analytical study. All patients with blunt head trauma underwent the initial Brain CT based on indications according to the guideline after six Hour of monitoring in the emergency room if they hadnchr(chr('39')39chr('39'))t any discharge conditions based on the indications in the guideline The brain controls CT was performed. Findings were analyzed by SPSS25 software. Chi-square, Independent T test, ANOVA and logistic regression were used. Results:  The results showed that 98.5% of the participants had no changes in their control CT scan. In the change group, 40% of cases had decreased hemorrhage, 35% of cases had increased hemorrhage and 25% of them had new intracranial hemorrhage. There was not also a statistically significant relationship between gender, drug history, outcome, initial CT-Scan findings, age, GCS score, systolic blood pressure, heart rate and duration with CT changes (in unchanged, exacerbated, recovered groups) (P> 0.05). But the results showed that the frequency of exacerbation of symptoms in people with underlying cranial disease was significantly higher than other groups (P=0.05). Conclusion: According to the results, it is possible that performing a primary CT scan in patients with head trauma in EDs is a good method for assessing the general condition of patients with mild to moderate trauma. However, evaluation of the necessity of control CT scan requires research with a larger sample size and longer follow-up.
