REVIEW OF LITERATURE
Kagan RJ et al found that mortality rates were 26.7 per cent, 36.5 per cent, and 41.4 per cent respectively for severe head injured patients in different input level 1 set up.
Fakhry SM, Trask AL, Waller MA, Watts DD in their study found overall mortality rate in a reducing pattern 1991-94 to 1997-2000 (17.8% vs. 13.8%), although this was not statistically significant.
REVIEW OF LITERATURE
Udekwu P. et al derived that mortality falls steeply between a Preresuscitation-GCS score of 3 and 7 followed by a shallow fall. Although P-GCS score is related to mortality in head-injured patients, its relationship is nonlinear, which casts doubt on its use as a continuous measure or an equivalent set of categorical measures incorporated into outcome prediction models.
AIIMS study ( present series) : Mortality as 3%, 15% ,35% for mild, moderate and severe head injury. This conforms to other study.
CONCLUSIONS
Incidence of head injury is increasing.
Post resuscitation GCS prognosticateS outcome.
Our mortality rates for head injured patients compare very favorably with international data.
