Computed Tomography Scan Head Findings in Patients With Various Glasgow Coma Scales Presenting with Head Injury in Emergency of a Tertiary Care Hospital

Objective: To associate the findings of CT scan with the Glasgow coma scale (GCS) of cases presenting with head trauma in the Emergency Department. Study Design: Cross-sectional study. Place and Duration of Study: Emergency Department, Combined Military Hospital, Rawalpindi Pakistan, from Jul to Dec 2021. Methodology: Ninty head injury cases of either gender, aged 12-60 years were included using non-probability consecutive sampling. The severity of the head injury was determined via GCS. CT scan findings were noted. Results: The mean age was 22.21±11.10 years. The highest frequency of patients was noted in the age group of (13-29 years).The most common cause of head injury in men was road traffic accidents n=39/58(67.24%). As per GCS scoring, 63.3% of patients had mild brain injury. A strong association was observed between GCS and CT scan findings in cases with brain oedema (p=0.002), skull fracture (0.018) and no findings on CT scan (p-value≤0.001). No association between findings on CT scan and GCS scoring was noted in cases with epidural, subdural hematoma, cerebral contusions, intracranial and subarachnoid haemorrhage. Conclusions: There is a lack of association between brain injury based on GCS scoring and CT scan findings. Using GCS scoring only for assessing the degree of brain injury is insufficient.Keywords: Computed tomography (CT) scan, Glasgow coma scales (GDS), Head injury.
