  • management of hypertension
  • prevention of complications
  • Call for help! – neonatologist, anaesthetist, obstetric team, ICU

Resuscitate

  • A – jaw thrust -> RSI ETT
  • B – FiO2 1.0, bag-mask, SpO2
  • C – left lateral position (prevent aorto-caval compression), IV careful fluids, BP
  • D – 4g MgSO4 IV over 5min -> infusion of 1g/hr for 24 hrs (therapeutic level = 2-4mmoL) – MAGPIE Trial

Terminate seizure

  • MgSO4 IV
  • Status epilepticus -> ?propfolol/thiopentone/diazepam (acknowledging effect on baby)
  • Anti hypertensive treatments (aim SBP 140-160mmHg) -> hyrdralazine, labetalol, nifidepine

Hypertension management

  1. methyldopa PO 0.5-3g/day

  3. nifedipine PO 10-20mg or IV 100-200mg over 2 min
  4. beta-blockers (metoprolol, pindolol, propanolol, esmolol)
  5. hydrallazine IV 10-20mg slowly
  6. GTN IV 0.1-0.8mcg/kg/min
  7. SNP IV 1-4mcg/kg/min

Prevention of complications

  • Planned delivery of baby
  • Monitoring for organ dysfunction (ICU)

Ongoing care

  • consideration and Investigation of other causes: epilepsy, hypoglycaemia, electrolyte abnormalities, LA toxicity, CNS pathology
  • BP control
  • fluid balance
  • monitoring for complications: ICH, CVA, pulmonary oedema, respiratory failure, hepatic failure, fetal loss
