HYPEREMESIS GRAVIDARUM Mrs.Jagadeeswari.J M.Sc Nursing INTRODUCTION HYPER : EXCESSIVE EMESIS : VOMIT GRAVIDARUM : PREGNANCY  Nausea/vomit of moderate intensity are especially common until about 16 week.  HCG occurs when vomiting becomes intractable in early pregnancy & cause fluid & electrolyte imbalances & nutritional deficiency.  women usually needs to be hospitalized. DEFINITION It is a severe type of vomiting of pregnancy which has got deleterious effect on health of the patient and/or incapacitates her day-to-day activities -D.C.DUTTA ETIOLOGY Limited to 1st trimester More common in 1st pregnancy Tendency to recur again in subsequent pregnancies Familial history: Mother and sisters also suffer from the same manifestation More prevalent in hydratiform mole and multiple pregnancy Common in unplanned pregnancies RISK FACTORS Age below 17 years and over 35 years Primigravidae Multiple pregnancy Underweight and obesity Psychological factors such as unwanted Pregnancy ,marital problems H/O Hyper emesis Gravidarum Trophoplastic disease Theories behind Hyper emesis Gravidarum 1.HORMONAL High Hcg-Hydratiform mole, multiple pregnancy High Estrogen High progesterone-relaxation of cardiac sphincter Other hormones involved: -Thyroxin -Prolactin -Leptin -Adreno-cortisol hormones 2.PSYCHOGENIC It probably aggravated nausea once it begins it trigger neurogenic elements. 3.DIETARY DEFICIENCY Probably due to low carbohydrate reserve as it happens after a night without food. Deficiency of vitamin B1,B6 & protein may be the effect rather than cause. Cont… 4.Allergic or immunological basis 5.Decrease gastric motility is found to cause nausea Clinical course Early: Vomiting throughout day Normal day to day activities are disturbed. No evidence of dehydration & starvation Late: Evidence of dehydration and starvation Cont.. SYMPTOMS: Excess vomiting & retching day & night. Epigastric pain Constipation Ptyalism Spitting Fatigue Anorexia Complications will appear if not treated Cont.. Signs: Signs of dehydration and ketoacidosis Dry coated tongue Sunken eyes Acetone smell in breath Tachycardia Postural hypotension Raise in temperature Jaundice(later stage) Vaginal examination and USG is done to confirm pregnancy investigation 1.Urinalysis Quantity (too see for oliguria) Dark colour (due to concentration) High specific gravity with acid reaction Presence of acetone, occasional presence of protein and bile pigments Diminished or even absence of chloride Cont… 2.Biochemical and circulatory changes Serum electrolytes (Sodium,Pottasium and Chloride) has to done Cont.. 3.Opthalmoscopic examination Its is required if patients is seriously ill. Retinal haemorrage and detachment of the retina are the most unfavorable signs Cont.. 4.ECG When there is abnormal serum potassium level diagnosis Pregnancy is confirmed first Associated causes of vomiting are excluded like Gynecological or Medical or Surgical causes, USG –Pregnancy, Hydratiform mole, Multiple pregnancy complications NEUROLOGICAL 1. Wernicke’s encephalopathy due to thiamine deficiency 2. Pontine myelinolysis 3. Peripheral neuritis 4. Psychosis 5. Ophthalmic: Retinal haemorrhage 6. Convulsions 7. Coma Other complications Stress ulcer in the stomach Oesophageal tears Jaundice due to liver damage prevention The only prevention is to import effective management to correct simple vomiting of pregnancy. management Principles: To control vomiting. To correct fluid & electrolyte imbalance. To correct metabolic disturbance. To prevent serious complications of severe vomiting. hospitalization Admit the patient Open IV line and correct fluids Send for relevant investigations Maintain an intake-output chart Monitor urine output (catheterize the patient) Monitor the vitals Test the urine periodically for ketone bodies fluids Oral feeding is withheld for at least 24 hours after the cessation of vomiting. During this period, fluid given through IV drip method. The amount of fluid to be infused in 24 hours is calculated as: total amount of fluid approx. 3litres, of which half is 5% is dextrose and half is Ringer’s solution. Extra amount of 5% dextrose equal to the amount of vomitus and urine in 24 hours, is to be added. These measures help to correct dehydration, electrolyte imbalance and keto- acidosis. Enternal nutrition through nasogastric tube may also be given drugs Antiemetic:- Promethazin -25mg IM BD or TDS Trifluopromazine -10mg IM Metachlopromide- 10mg IM Hydrocortisone:- 100mg IV in drip Prednisolone orally Nutritional support:- Vitamin B1, vitamin B6, vitamin B12 & vitamin C Nursing care Sympathetic but firm handling of patient Daily monitoring of the patient Look for signs of improvement in the patient: subsidence of vomiting, feeling hungry, better look, disappearance of acetone from breath and urine, normal pulse and blood pressure, normal urine output. Monitor lab results for dehydration Monitor FHR,Fetal activity and growth Encourage patient to sit in upright after meal Encourage small & frequent meals. Liquids should be taken between meals to avoid distending stomach and triggering vomit Obstetric care No therapeutic abortion is indicated if patient improve on therapy. Therapeutic abortion is seldom indicated on pregnancy associated with renal or neurological complications. Dietary management Before IV fluids is given oral Small and frequent dry meals without fat are given.
