Evaluation the accuracy of PECARN Rules in prediction the Brain Injuries in Pediatric with Head Trauma

Abstract

CT scan is one of the first and foremost measures for head trauma in emergency centers and is the standard diagnostic tool for examining brain injuries caused by trauma.However, the use of CT scans to check for head trauma in children was not without risk. Also, despite its frequent use to detect brain damage, 90% of cases were not damaged and less than 1% of cases required emergency measures.Since the studies performed to evaluate the PECARN results have contradictory results. Accordingly, we decided to design a descriptive cross-sectional study to evaluate the diagnostic value of this method. Materials and Methods: The injured children were visited by the etching and residents present at the center and were examined and treated according to the treatment guidelines. According to the PECARN age-based rules, children were divided into three categories: low risk, moderate risk and high risk Classified according to PECARN rules. For all three groups, if there is an indication based on the available references of emergency medicine, ATLS and brain surgery, CT scan was performed by Siemens device (Siemens SOMATOM Emotion 6, Germany) and CT scan was reported by Atend resident emergency. Event The results of the PECARN rules and CT scans were compared in the diagnosis of brain damage of clinical significance. In this study, sensitivity, specificity, positive and negative predictive value with 95% confidence interval were calculated to evaluate the diagnostic value (accuracy) of PECARN rules for the occurrence of head trauma of clinical significance. Results: In this study, 250 patients were studied and the average age of the children was about 88 months. In this study, 182 cases were CT scanned, of which 802 had a positive CT scan. In the results, 6.3% of patients with positive CT scan in the low-risk PECARN group, 38.8% of patients with positive CT scan in the moderate risk group and 55% in the high risk group had PECARN criteria.
