Convulsions may be due to eclampsia, epilepsy, malaria, head injury,
cerebral abscess, meningitis, encephalitis, etc.
Whatever the cause, initial steps are the same.
Examination
General ------------------------- Oedema ----------------? Eclampsia
External injuries ----- ? Head injury
CVS ----------------------------- Hypertension----------? eclampsia Pulse, heart
RS ------------------------------- Crepitations& rhonchi
CNS ----------------------------- Pupils (if unequal)---- ? Cerebral abscess
Neck rigidity --------- ? Meningitis
? Encephalitis
Planter reflex
Level of consciousness
Abdomen ----------------------- Confirm pregnancy
If less than 16 weeks ---? Epilepsy
Hepatosplenomegaly --- ? Malaria
Administer hydrallazine 10 mg I.V. slowly repeat even} 30 minutes till diastolic BP is 90-100 mmHg.
However, sometimes the fits may not stop with this treatment and you may
have to transfer the patient before fits are completely controlled.
c) Additional measures
Indwelling urinary catheter - Keep opened during transfer also.
Check for proteinuria.
Whatever the cause, initial steps are the same.
- Stop the fits
- Maintain airway
- Prevent aspiration
- Prevent injuries
Immediate care :
- Position the patient - head low, turn to a side
- airway - plastic or metal
- Suck the mouth and pharynx
- Place cushions around the patient or tie the limbs loosely with soft cloth
- Diazepam 10 mg I.V. slowly (2 min.)
- Insert an I.V. cannula & splint the arm
Quick history from a bystander
History of epilepsy, malaria, fever, head injury, POA, hypertension, antenatal clinic records
General ------------------------- Oedema ----------------? Eclampsia
External injuries ----- ? Head injury
CVS ----------------------------- Hypertension----------? eclampsia Pulse, heart
RS ------------------------------- Crepitations& rhonchi
CNS ----------------------------- Pupils (if unequal)---- ? Cerebral abscess
Neck rigidity --------- ? Meningitis
? Encephalitis
Planter reflex
Level of consciousness
If less than 16 weeks ---? Epilepsy
Hepatosplenomegaly --- ? Malaria
Impending eclampsia
This means fits have not started but may start at any time.
Symptoms
and signs
Severe headache
Visual changes ------------------ Blurring of vision
Seeing flashes of light or spots
photophobia
Restlessness
Epigastric pain, nausea, vomiting
Severe hypertension - diastolic BP of120 mmHg or more
Exaggerated knee jerk
If eclampsia or impending eclampsia
is diagnosed,
- Prevent or control fits
- Control hypertension
- Maintain airway
- Transfer
Further drug treatment
a) Antihypertensive
If diastolic BP > 100 mmHg
Puncture a capsule of nifedipine 10
mg and squeeze the
contents into the area under the tongue
Or
Or
Administer hydrallazine 10 mg I.V. slowly repeat even} 30 minutes till diastolic BP is 90-100 mmHg.
However, sometimes the BP may not come down with this and you may have to transfer
the patient with diastolic BP above 100mmHg.
b) Anticonvulsants
- Mgso4g iv infusion 15mm+
- Maintenance dose 1g/hour
- Ensure UOP >30ml/m
- Chart BP, RR, PR 1/4hourly
- Start 20 mg diazepam in 500 cc of 5% dextrose and run it fast until the patient is deeply sedated. E.g. Responds to deep pain but very sleepy.
- Ensure that respiratory rate is not less than 15 per min.
- Keep 10 mg diazepam in a syringe to be given if fits recur.
- Transfer to a specialist unit.
Indwelling urinary catheter - Keep opened during transfer also.
Check for proteinuria.
Before Transfer -
- Make sure that the patient is well sedated i.e. responds to pain but very sleepy.
- Try to bring down the diastolic BP to 100 mmHg.
- Ensure that respiratory rate is above 15 per min.
- Ensure that the Airway is in place and secretions are sucked out.
- Telephone the specialist unit prior to transfer.
- To accompany the patient, a nurse may be better than a midwife if you have adequate staff because it may be necessary to repeat I.V. diazepam during transfer.
- Keep the patient turned to a side during the journey.
