  3. 3. Objectives  Introduction.  Epidemiology.  Clinical picture.  Investigation.  Treatment.  outcomes.
  4. 4. Introduction Nausea and vomiting in pregnancy is extremely common. The nausea and vomiting associated with pregnancy usually begins by 9-10 weeks of gestation, peaks at 11-13 weeks, and resolves in most cases by 12-14 weeks. Normal nausea and vomiting may be an protective mechanism—it may protect the pregnant woman and her embryo from harmful substances in food.
  5. 5. Definitions Motion sickness: Nausea felt by pregnant woman on getting up in the morning. Emesis gravidarum: actual vomiting in the morning. Hyperemesis gravidarum: Vomiting not confined to morning but repeated throughout the day until it affect the general condition of the patient.
  6. 6. Epidemiology Incidence: Of all pregnancies, 0.3-2% are affected with HEG . more common in westernized industrialized societies and urban areas than rural areas. Race: No clear racial predominance is noted for HEG
  7. 7. Risk factors Previous pregnancies with HEG Greater body weight Multiple gestations Trophoblastic disease Nulliparity The risk of HEG appears to decrease with advanced maternal age. Cigarette smoking is associated with a decreased risk for HEG.
  8. 8. Aetiology Unknown. Hormonal. Psychological. Vestibular and olfaction Hepatic dysfunction . Lipid alterations . Other (H.pylori infection)
  9. 9. Aetiology cont. Hormonal: Women with hyperemesis gravidarum often have high hCG levels that cause transient hyperthyroidism. High human chorionic gonado trophin (hCG) stimulate the chemo receptor trigger zone in the brain stem including vomiting center. Evidence by High hCG in : Early pregnancy. Vesicular mole. Multiple pregnancy.
  10. 10. Aetiology cont. H . pylori infection: 1-The incidence of H.pylori sero positive in patients with hyperemesis gravidarum (HG) is high in comparison with non-HG pregnant women . ive t ni efi ion o d lat  no one was able to demonstrate correlation or t N re cH. pylori and the between seropositivity for fa or c le time of onset or tduration of HG symptoms. l ip  Although H.M u pylori infection may be an importantm factor in exacerbating HG, it may not represent the sole cause of the disease.
  11. 11. Diagnosis History. Examination.
  12. 12. Clinical picture (symptoms) Vomiting through day and night ptyalism dizziness Sleep disturbance Hyperolfaction Dysgeusia Depression Anxiety Irritability Mood changes Decreased concentration

  16. 16. Investigations Urinalysis: for ketones and specific gravity . Serum electrolytes : -low Na or K. -hyperchloremic metabolic alkalosis or acidosis. LFT: Elevated transaminase levels . TSH,free thyroxine :HEG is associated with hyperthyroidism
  17. 17. Investigations cont Urine culture: UTI can be associated with nausea and vomiting. Hematocrit: This may be elevated. Hepatitis screening: hepatitis A, B, or C may be confused with HEG.
  18. 18. Investigations cont Imaging Studies: Obstetric ultrasonography : evaluate for multiple gestations or trophoblastic disease. upper abdominal ultrasonography to evaluate the pancreas and/or biliary tree In rare cases, abdominal CT scan may be indicated if appendicitis is under consideration.
  19. 19. Management 1-Admission: 2-Intravenous Fluids: Normal saline or lactated Ringer’s solution is the mainstay of intravenous fluid therapy. It should be given by infusion over 2-3 hours. thiamine (vitaminB1). 3-Enteral or Parenteral Nutrition.
  20. 20. Management cont DIETARY AND LIFESTYLE CHANGES  Separating solids and liquids.  Eating small, frequent meals consisting of bland     foods. Avoiding fatty foods such as potato chips. Avoiding drinking cold or sweet beverages. Eliminate pills with iron High protein snacks are helpful.
  21. 21. Management cont 5 - PHARMACOLOGICAL THERAPIES:  Vitamins Pyridoxine (Nestrex)  Essential for normal DNA synthesis and play a role in various metabolic processes (Diclectin) combination of doxylamine with of pyridoxine (vitamin B6) A - Safe in pregnancy at a dose of 10-12.5 mg PO qd/bid.
  22. 22. Management cont Antiemetics : a.DOPAMINE ANTAGONISTS: Useful in the treatment of symptomatic nausea - phenothiazines (i.e., chlorpromazine, perphenazine, prochlorperazine, promethazine, trifluoperazine) - blocking postsynaptic mesolimbic dopamine receptors through anticholinergic effects and depressing reticular activating system - C - Safety for use during pregnancy has not been established.
  23. 23. Management cont Metoclopramide:is an upper gastrointestinal motility stimulant. Blocks dopamine receptors and (when given in higher doses) also blocks serotonin receptors in chemoreceptor trigger zone of the CNS Metoclopramide is safe to be used for management of NVP, although evidence for efficacy is more limited B - Usually safe but benefits must outweigh the risks
  24. 24. Management cont SEROTONIN 5-HT3 ANTAGONISTS.  Ondansetron (Zofran) : blocking serotonin, both peripherally on vagal nerve terminals and centrally in the chemoreceptor trigger zone In general, 5-HT3 antagonists may be safe to use during the first trimester, but the data are scant.
  25. 25. Management cont Antihistamines : Meclizine (Antivert) , Diphenhydramine (Benadryl) Appears to be as efficacious as pyridoxine Causes sedation; caution must be used in performing tasks which require alertness
  26. 26. Management cont Corticosteroids: Methylprednisolone (Medrol, Solu-Medrol) Recent studies revealed a small but significantly increased risk of oral clefting associated with first trimester exposure to corticosteroids.
  27. 27. Management cont A doxylamine/ pyridoxine combination should be the standard of care since it has the greatest evidence to support its efficacy and safety. Other drugs may also be used, primarily dimenhydrinate, in conjunction with the doxylamine/pyridoxine combination. If possible, corticosteroid use should be avoided in the first 10 weeks .
  28. 28. Management cont Other modalities: (antidepressent): - Selective serotonin re-uptake inhibitors - Tricyclic antidepressants (TCAs) Helicobacter pylori eradication. ACUPUNCTURE. Stimulation of the P6 point, located three-fingers’ breadth proximal to the wrist, has been used for treat nausea and vomiting Ginger (Zingiber officinale)
  29. 29. outcomes Esophageal rupture or perforation Pneumothorax and pneumomediastinum Wernicke encephalopathy or blindness Hepatic disease Seizures, coma, or death HEG is self-limited and, in most cases, improves by the end of the first trimester. However, symptoms may persist through 20-22 weeks of gestation and, in some cases, until delivery.
