Non-traumatic coma in Zambia

Abstract

A series of 170 patients with non-traumatic coma seen over a 16-month period is reported. The Glasgow coma scale significantly correlated with outcome (P less than 0.001). The diagnosis was also important in determining outcome. Hospital mortality was lowest in patients with cerebral malaria (22.7%), eclamptic coma (36.4%), and organophosphorous poisoning (30.4%). A diagnostic approach to non-traumatic coma is outlined and the management of the different causes is discussed. Most hospitals in tropical Africa should be able to diagnose up to 90% of cases with non-traumatic coma and simple therapy is likely to be effective in the majority of cases.
