Clinical and investigational study for the aetiological evaluation of patients in nontraumatic altered sensorium and its outcome

Background: Apart from head injury many patients present to the tertiary care hospital in unconscious state, the etiology of which is obscure in most of the cases. The present study was conducted with on objective to provide insight into the clinical features and diagnostic methods to know the aetiology of patients with non-traumatic cases of altered sensorium and to study the outcome of these patients.Methods: This is an observational study on 100 patients of altered sensorium of non-traumatic origin during the period from October 2012 to September 2014 conducted in the Department of General Medicine, MKCG Medical College Hospital, Berhampur, Odisha, India. All patients were selected for the study based on the inclusion exclusion criteria. Detailed history, clinical evaluation, laboratory investigations like neuroimaging studies etc. were carried out. Statistical data analysis was done using Graph pad Prism 6 and Microsoft Excel. P value <0.0001 was considered statistically extremely significant.Results: Out of 100 patients of altered sensorium, 64 were males and 36 were females. All patients were in the age group of 19 to 89 years. Cerebrovascular accident was the most common aetiology of altered sensorium followed by metabolic encephalopathy and infection. Altered sensorium in patients with CVA carries a high mortality. Metabolic causes and younger age indicated a better prognosis, patients with low (Glasgow Coma Score) GCS score of 3 to 4 had poorer prognosis.Conclusions: The results suggest that clinical assessments yield accurate predictive information about the potential for recovery in cases of altered sensorium. So, this study concludes that empirically based estimates of prognosis in the neurologically severely ill provides great reassurance to those involved in a decision-making process, including patients’ families and physicians.

Full Outline of Unresponsiveness score and the Glasgow Coma Scale in prediction of pediatric coma / 世界急诊医学杂志（英文）

@#BACKGROUND: This study was done to compare the admission Full Outline of Unresponsiveness (FOUR) score and Glasgow Coma Scale (GCS) as predictors of outcome in children with impaired consciousness. METHODS: In this observational study, children (5–12 years) with impaired consciousness of <7 days were included. Children with traumatic brain injury, on sedatives or neuromuscular blockade; with pre-existing cerebral palsy, mental retardation, degenerative brain disease, vision/hearing impairment; and seizure within last 1 hour were excluded. Primary outcomes: comparison of area under curve (AUC) of receiver operating characteristic (ROC) curve for in-hospital mortality. Secondary outcomes: comparison of AUC of ROC curve for mortality and poor outcome on Pediatric Overall Performance Category Scale at 3 months. RESULTS: Of the 63 children, 20 died during hospital stay. AUC for in-hospital mortality for GCS was 0.83 (CI 0.7 to 0.9) and FOUR score was 0.8 (CI 0.7 to 0.9) [difference between areas –0.0250 (95%CI 0.0192 to 0.0692), Z statistic 1.109, P=0.2674]. AUC for mortality at 3 months for GCS was 0.78 (CI 0.67 to 0.90) and FOUR score was 0.74 (CI 0.62 to 0.87) (P=0.1102) and AUC for poor functional outcome for GCS was 0.82 (CI 0.72 to 0.93) and FOUR score was 0.79 (CI 0.68 to 0.9) (P=0.2377), which were also comparable. Inter-rater reliability for GCS was 0.96 and for FOUR score 0.98. CONCLUSION: FOUR score was as good as GCS in prediction of in-hospital and 3-month mortality and functional outcome at 3 months. FOUR score had a good inter-rater reliability.

Approach to the Child with Coma.

Coma and other states of impaired consciousness represent a medical emergency. The potential causes are numerous, and the critical window for diagnosis and effective intervention is often short. The common causes of non-traumatic coma include central nervous system infections, metabolic encephalopathy (hepatic, uremic, diabetic ketoacidosis etc.), intracranial bleed, stroke and status epilepticus. The basic principles of management include 1) Rapid assessment and stabilization, 2) Focussed clinical evaluation to assess depth of coma, localization of lesion in the central nervous system and possible clues to etiology, and 3) Treatment including general and specific measures. Commonly associated problems such as raised intracranial pressure and seizures must be recognized and managed to prevent secondary neurologic injury.
