Association of meningitis with infantile gastro-enteritis.

It is the policy at the Jordan University Hospital to perform lumbar puncture on children with gastroenteritis who present with one or more of the following: age less than 1 month, convulsions, hypoactivity or marked irritability, and depressed sensorium. Review of the records of 737 children admitted with gastro-enteritis between January 1980 and October 1984 showed that lumbar puncture was performed on 351 (47.6%) children. Acute bacterial meningitis was diagnosed in only three children, two of whom had already received treatment before admission and the third had obvious meningeal signs. These findings do not justify the present policy on lumbar puncture in children with gastroenteritis and it is proposed that the procedure be reserved for children in whom abnormal CNS findings persist after initial correction of fluid and electrolyte balance or with overt signs of meningitis.
