12. CLINICAL FEATURE it is grand mal convulsion which pass through stages of: 1. Tonic contraction 2. Clonic 3. Coma Usually take about 60-90 seconds. www.doctor.sd

13. EDEN’S CRITERIA OF SEVERITY  Coma take 6 hours or more  SBP reach 200 mmHg  Tm 39 or more  Pulse rate 120/min  RR 40/min  2 fits or more All this can end in maternal brain death www.doctor.sd

16. 1. Usually unnecessary to try to stop the initial convulsion which usually last about 60-90 seconds 2. IV Diazepam slowly 5mg over 1 min 3. 3. Roll the patient on his left side to avoid maternal injury www.doctor.sd

17. 4. Apply Suction to the secretion from her mouth 5. Adequate Oxygen should be maintained by face mask & airways to prevent swallowing of tongue 6. Prevent further convulsions by MgSO 4 by IV bolus of 4 – 6 g over 15 min. If convulsion recur further bolus of 2g. 7. Acidosis should be corrected if necessary by IV NaHCO 3 8. SBP 170 mmHg or more, DBP 110 mmHg is risk factor for CVA so should be lowered by either Nifedipine 10 – 20 mg SL. Or Hydrallazine 5mg followed by infusion. www.doctor.sd
