Hyperemesis Gravidarum

Nausea and vomiting in pregnancy is common and at best an unpleasant experience for the patient, and at worst can be life threatening. It normal starts @ 4-7/40, peaks @ 9/40, and finishes @ 20/40.

We need to conduct a thorough history and examination looking for causes other than a high βHCG. these include:

  • Abdominal pathology
  • Urinary pathology
  • Infections
  • Drug History
  • Chronic H.Pylori

  • Women that are accepted to GAU from HRI may be considered for transfer using own transport if they can be driven to CRH and have NEWS2 of 3 or less after initial hydration and parenteral antiemetics
