Vomiting as an Indicator for CT Brain Following Head Injury in Pediatric Age Group.

Background: Vomiting is a frequent occurrence following head injuries. Isolated vomiting was a significant indicator of intracranial injury following a head injury. Following head trauma, CT (computed tomography) is a quick and reliable method for patients with head injuries. Aim of Study: To detect if vomiting is a good predictor of requesting a CT scan. Patients and Methods: This was retrospective research that was conducted on 200 patients with head trauma. These patients presented to the emergency department, at Beni-Suef Universi-ty Teaching Hospital, Egypt. The period of the research was from January 2022 to June 2022. Results: Regarding the demographics the mean age was 7.8±4.2 and the mean BMI was 24.9±4.3. Regarding the preva-lence and onset of vomiting, the majority of patients 140 (70%) had recurrent episodes of vomiting and onset of vomiting the majority of patients 70 (35%) had vomiting within 1h after trau-ma, while 30 patients (15%) had vomiting 1–4h after trauma and in 5 patients (2.5%) had vomiting >4h after trauma. Conclusion: Most patients with single vomiting episodes had normal CT scans 96%. While in recurrent episodes of vom-iting, around a third of the cases experienced positive CT scan findings. Thus, recurrent episodes of vomiting could be utilized as a good predictor of a CT scan following head trauma in pedi-atrics while single episodes of vomiting are considered a poor indicator.
