mhGAP-IG base course - field test version 1.00 – May Summary for acute seizure management 1.Why is the management of seizures an emergency 1.Prolonged seizures can cause brain injury and death 2.Seizures can be a symptom of another disease (e.g. meningitis) 2.If a person presents convulsing in your clinic, what are the initial actions that you should take 1.ABC and positioning 2.Asses and manage simultaneously

mhGAP-IG base course - field test version 1.00 – May Key messages from acute seizure management Seizures are a symptoms not a cause, you need to look for a cause If the person presents convulsing it is an emergency and needs to be treated urgently a) seizures can a sign of a life-threatening problem b) seizures can result in brain injury or death! In persons who are having seizures, assessment and management should be done at the same time
