摘要

Purpose

Computed tomography of the head (CTH) is the primary imaging modality for traumatic brain injury (TBI), but the necessity of routine repeat CTH (RRCTH) in mild TBI remains unclear. We aim to assess whether RRCTH within 24–48 h after mild TBI influences clinical decision-making and patient management.

Methods

This prospective observational study included mild TBI patients admitted to a tertiary care hospital between June 2022 and January 2024, who underwent routine RRCTH without immediate surgery. Patients < 18 years old, those with moderate/severe TBI, neurological comorbidities, immediate surgery, or early death (≤ 24 h) were excluded. Statistical analysis was performed using the JASP statistical software (Pearson’s chi-squared test, Fisher’s exact test, Mann–Whitney U test).

Results

Seventy patients (18 female) were included (mean age: 56.20 ± 20.44 years; mean admission Glasgow Coma Scale: 14.59 ± 0.67). RRCTH was performed at 32.58 ± 24.13 h (mean) post-injury. Radiological and neurological deterioration occurred in 22 (31.43%) and 8 (11.43%) patients, respectively. Although radiological worsening was linked to neurological decline (OR = 8.63, 95% CI = 1.58–47.17, P = 0.010), only one (1.43%) patient required surgery based on RRCTH findings alone.

Conclusion

RRCTH within 24–48 h in mild TBI correlates with clinical deterioration but does not impact management.
