Abstract The prevalence of hyperemesis gravidarum is approximately 0.3-3% of pregnancies and varies on account of different diagnostic criteria and ethnic variation in study populations. There is a broad spectrum of nausea and vomiting of pregnancy (NVP) severity, ranging from mild, occasional nausea to severe, intractable vomiting requiring hospitalization.(Jarvis and Nelson-Piercy, 2011) Hyperemesis gravidarum (HG) is a form of severe nausea and vomiting in pregnancy (NVP) associated with significant impairment of oral intake and weight loss of at least 5% compared with pre-pregnancy, with or without dehydration and/or electrolyte abnormalities, which affects about 0.3–3.6% of pregnant women. Admission for hyperemesis gravidarum depends on clinical impression by the attending or referring physician. There is a need for classification the severity of NVP to restrict admission to those who need admission. An objective and validated index of nausea and vomiting such as the Pregnancy-Unique Quantification of Emesis (PUQE) score may be used for this purpose. This questionnaire contains three questions regarding the time-span of nausea, vomiting and retching respectively, as well as one question assessing the global psychological and physical quality of life (QOL). Initially the questionnaire evaluated symptoms during last 12 hours, but it has been modified to encompass 24 hours as well as the whole of first trimester of pregnancy. |
