Objective To investigate the types and incidence of common sequelae in children with bacterial meningitis.To investigate the risk factors for adverse outcome of childhood bacterial meningitis. Methods Selected 129 children with bacterial meningitis all cases were divided into adverse outcome group and favorable outcome group.According to the incidences of different kinds of sequelae,The risk factor effecting bad prognosis were studied. Results A total of 80 children were successfully followed.Of them,12 might only have mild sequelae and 13 had serious sequelaes.Among these children who had serious sequelae,11 of them had mental retardation,8 of them had motor deficit,4 of them had bilateral hearing loss and 4 of them had secondary epilepsy.10 children had multiple serious sequelae,thes most common multiple impairment combinations were mental retardation plus motor deficit.48 parents of the children completed the Child Behaviour Checklist and found out 17(35.42%)of their children had behavioral disorders.Adverse outcome group and favorable outcome group,the length of fever(>7 days),repeated convulsions after admission(≥3 times),coma(Glasgow coma scale score <8 points),septic shock,abnormal pupils,limb movement disorder.There were significantly difference between the two groups(P＜ 0.05). Conclusions This study showed that there are different kinds of sequelaes of children with bacterial meningitis,it indicated that these children should be follow-up to track the effect.On the other hand,this study found out that the high risk factors with adverse outcome might be coma,septic shock and so on.It indicated that if we could identify the high risk factors in the early stage and then interpose them immediately,it might beneficial to improve the quality of life of the children.
