2 Nausea and vomiting in pregnancy is extremely common. Severe hyperemesis requiring hospital admission occurs in 0.3-2% of pregnancies. Hyperemesis gravidarum (HEG) is the most severe form of nausea and vomiting in pregnancy.

6 Studies estimate that nausea and vomiting occurs in 50-90% of pregnancies. begins by 9-10 weeks of gestation, Lacroix and co-workers (2000) found that it is lasted an average of 35 days. peaks at weeks, resolves in most cases by weeks. In 1-10% of pregnancies, symptoms may continue beyond weeks. Cunningham FG, et.al. 23rd edition Williams Obstetrics. McGraw Hill: New York; 2010.

7 Normal nausea and vomiting may be an evolutionary protective mechanism it may protect the pregnant woman and her embryo from harmful substances in food, such as pathogenic microorganisms in meat products and toxins in plants, with the effect being maximal during embryogenesis (the most vulnerable period of pregnancy). Studies shows that women who had nausea and vomiting were less likely to have miscarriages and stillbirth.

17 TREATMENT

18 Seldom is the treatment of nausea and vomiting of pregnancy so successful that the affected expectant mother is afforded complete relief. Fortunately, the unpleasantness and discomfort usually can be minimized. Eating small meals at more frequent intervals but stopping short of satiation is valuable. Borrelli and colleagues (2005) did a systematic literature search and reported that the herbal remedy, ginger, was likely effective. Mild symptoms usually respond to vitamin B6 given along with doxylamine, but some women require phenothiazine or H1- receptor blocker antiemetics (American College of Obstetricians and Gynecologists, 2004b). In some women, vomiting may be so severe that dehydration, electrolyte and acid base disturbances, and starvation ketosis become serious problems.

21 Deteksi komplikasi HG Dehidrasi > syok, hambat tumbang janin Gangguan keseimbangan elektrolit > alkalosis metabolik hipokloremik, hiponatremia, hipokalemia Ketosis > intake sulit, lemak dioksidasi > penumpukan aseton: bau napas aseton Pada lab : peningkatan relatif Hb, Ht, hiponatremia, hipokalemia, keton dalam darah Ruptur esofagus ringan, pneumothorax HG dengan kenaikan BB hamil < 7 kg > BBLR, KMK, prematur, apgar menit ke-5 < 7 Wernicke encephalopathy > trias: Oftalmoplegia, ataksia, confusion

22 Evaluasi keberhasilan terapi Tujuan > mencegah komplikasi Klinis: penurunan frekuensi muntah, mual, perbaikan TTV, status hidrasi baik, Lab: perbaikan asam basa dan elektrolit

23 Other keypoints Pemeriksaan lab yg penting saat awal penemuan HEG adalah cek keton pada urin Tentukan usia kehamilan, muntah brp kali, deteksi tanda komplikasi, ada dehidrasi/syok, perbaiki tanda-tanda umum, periksa DPL Cek urin saat pasang kateter, keton (+) artinya ada metabolisme anaerob > metabolisme CHO tdk berjalan > puasakan Kateter > hitung balans cairan (>1ml/kgBB/jam) Cari underlying cause > gastritis? mola hidatosa? gemelli? Ondansetron dapat diberikan HEG yg utama elektrolit > puasakan > diet parenteral
