Intracranial volume pressure response in infants and children: preliminary report of a predictive marker in metabolic coma

Abstract

Intracranial volume-pressure response was assessed in 6 children suffering from metabolic coma and ranging in age 2 months-13 years. No untoward pressure or infectious complications occurred. The relationship between baseline mean intracranial pressure (MICP) and volume-pressure response assessment (VPRA) in these patients seems to be exponential rather than linear. By itself, the test is no better than baseline MICP at identifying patients at greatest risk of developing significantly increased intracranial pressure (ICP). When used in conjunction with baseline MICP, this method of VPRA identifies a population with an 80% risk of developing serious ICP elevations within a 4 h time period. Patients with best overall prognosis had significantly lower mean VPRA values than those with poorest overall prognosis.
