Abstract

Background: The study aimed to assess the relationship between computed tomography (CT) scan findings and Glasgow Coma Scale (GCS) score with the purpose of introducing GCS scoring system as an acceptable alternative for CT scan to clinically management of brain injuries in head trauma patients. Materials and Methods: This study was conducted on hospitalized patients with the complaints of head trauma. The severity of the head injury was assessed on admission by the GCS score and categorized as mild, moderate, or severe head injury. Results: Of all study subjects, 80.5% had GCS 13–15 that among those, 45% had GCS 15. Furthermore, 10.5% had GCS ranged 9–12 and 9% had GCS <8. Of all subjects, 54.5% had abnormal CT findings that of them, 77.1% categorized as mild head injury, 11.0% had a moderate head injury, and 11.9% had a severe head injury. Furthermore, of those with GCS 15, 41.0% had abnormal CT scan. Of all patients with abnormal CT findings, 33.0% underwent surgery that 61.1% categorized in mild head injury group, 13.9% categorized in moderate head injury group, and 22.2% categorized in severe head injury group. Of those with GCS equal to 15, only 27.0% underwent surgery. Conclusion: The use of GCS score for assessing the level of injury may not be sufficient and thus considering CT findings as the gold standard, the combination of this scoring system and other applicable scoring systems may be more applicable to stratify brain injury level.

Computed tomography versus plain radiography to screen for cervical spine injury: a meta-analysis.

Avram J. Holmes, Radha Akkinepalli (2005)

To compare the test performance of plain radiography and computed tomography (CT) in the detection of patients with cervical spine injuries following blunt traumatic events among those patients determined to require screening radiography. We conducted a MEDLINE search for articles published from January 1995 through June 2004, manually reviewed bibliographies, and hand searched four journals. Studies were included if they contained data on the performance of both plain radiography and CT in the detection of patients with blunt cervical spine injuries. Both authors screened titles and abstracts identified by the search and seven of the 712 articles met all inclusion criteria. Both authors independently abstracted data from these seven studies and disagreements were resolved by mutual agreement. Patient entry criteria were highly variable for each study and there were no randomized controlled trials. For identifying patients with cervical spine injury, the pooled sensitivity for cervical spine plain radiography was 52% (95% CI 47, 56%) and for CT was 98% (95% CI 96, 99%). The test for heterogeneity suggests that significant differences exist between studies in the measurement of the sensitivity for plain radiography (p = 0.07). Due to limitations of the gold standard tests in each study, a calculation of a combined specificity was not possible. Despite the absence of a randomized controlled trial, ample evidence exists that CT significantly outperforms plain radiography as a screening test for patients at very high risk of cervical spine injury and thus CT should be the initial screening test in those patients with a significantly depressed mental status. There is insufficient evidence to suggest that cervical spine CT should replace plain radiography as the initial screening test for less injured patients who are at low risk for cervical spine injury but still require a screening radiographic examination.

Systematic selection of prognostic features in patients with severe head injury.

J Minderhoud, R Braakman, G J Gelpke … (1980)

In this study small sets of clinical features were identified that, when combined, yield high quality predictions of long term outcome. The study is based on a series of 305 consecutive head-injured Dutch patients, all of whom had been in coma for at least 6 hours. The overall social outcome was assessed after 6 months using the Glasgow outcome scale. Predictions of outcome were made by assigning probabilities to each possible outcome category. The prognostically most promising features recorded during the early post-traumatic course were identified, and powerful combinations of prognostic features were selected on admission and 1, 3, 7, 14, and 28 days after the start of coma by an appropriate statistical method. At each time point, optimal prediction required sets of only three to five features, typically including age in decades, depth and duration of coma as assessed by the Glasgow coma scale, pupil reactivity to light, and spontaneous and reflex eye movements. The method described allows bedside predictions in individual patients and provides a tool for comparing the severity of injury between series of patients.

Extradural hematoma: toward zero mortality. A prospective study.

A Bricolo, L Pasut (1983)

This is a prospective analysis of 107 consecutive cases of extradural hematoma treated during the last 3 years at the Department of Neurosurgery of the University Hospital of Verona (Italy). The overall mortality was 5%; 89% of the patients made a good recovery or had only moderate residual disability. We regard this as meaningful progress compared to recent reports from other sources showing mortality rates of approximately 20%. The majority of our patients (57%) underwent operation within 6 hours of injury; 60% went into surgery with a Glasgow coma scale (GCS) score between 8 and 15. No deaths occurred among patients reaching surgery with a GCS score of 8 or better; all patients with scores of 8 to 15 made a good recovery (63 cases). Seventeen patients went into surgery while still free of neurological signs, and 8 had only one dilated pupil; all 25 made good recoveries. A flexion posture at admission cuts the chances of a good outcome by one-half; an extension posture cuts the chances to one-fourth. Ninety-five per cent of the patients had fractures of the skull; only 21% had the classical lucid interval. The cause of all 5 deaths was identified as stemming from avoidable errors in management in outlying hospitals (2 cases) or in our own department (3 cases). The results of this study indicate that zero mortality from extradural hematoma is a realistic goal for a modern, well-run care system for head-injured patients that includes prompt referral by community doctors and suitable hospital facilities for constant access to emergency neurosurgery.
