Children <3 years of age in developing countries experience around three episodes of diarrhoea each year. Definition : Definition Diarrhoea is the passage of loose or watery stools at least three times in 24 hour . Clinical Types : Clinical Types Acute watery diarrhoea (including cholera): Lasts several hours or days Main danger is dehydration Weight loss occurs if feeding is not continued; Acute bloody diarrhoea: Also called dysentery Main dangers - damage of the intestinal mucosa, sepsis and malnutrition Other complications : dehydration , HUS Slide 5: Persistent diarrhoea : Lasts 14 days or longer a/w malnutrition Main danger - malnutrition & serious non-intestinal infection Other complications : dehydration Diarrhoea with severe malnutrition : Main dangers - severe systemic infection , dehydration, heart failure and vitamin and mineral deficiency. ETIOLOGY OF ACUTE DIARRHOEA : ETIOLOGY OF ACUTE DIARRHOEA Viral : Rota Virus Adenovirus Norwalk Agent Bacterial : V. Cholera ETEC, EIEC Salmonella Shigella Campylobacter Fungal : Candida Slide 7: Parasitic Infection : Giardia Lamblia Cryptosporidium Entamoeba Histolytica Drugs : Laxatives Sorbitol Antacids Lactulose Theophylline Antibiotics Quinidine Diet : Food Poisoning Food allergy Pathophysiology of acute diarrhea : Pathophysiology of acute diarrhea Increased secretion of fluid and electrolytes Decreased digestion and absortion of nutrients Abnormal transit due to aberrations of intestinal motility Assessment of the child with diarrhoea : Assessment of the child with diarrhoea History Ask the mother or other caretaker about: Presence of blood in the stool; Duration of diarrhoea; Number of watery stools per day; Number of episodes of vomiting; Presence of fever, cough, or other important problems (e.g. convulsions, recent measles); Pre-illness feeding practices; Type and amount of fluids (including breastmilk) and food taken during the illness; Drugs or other remedies taken; Immunization history. Slide 10: Dysentery: Mucous & blood in stool Persistent diarrhoea: Min 14 days Malnutrition with diarrhoea: Weight-for-length or weight-for-age indicate moderate or severe malnutrition Oedema with muscle wasting Obvious marasmus Dehydration : Dehydration During diarrhoea there is an increased loss of water and electrolytes (Na, Cl , K , and HCO3 ) in the liquid stool. Dehydration occurs when these losses are not replaced adequately and a deficit of water and electrolytes develops. Slide 12: NO DEHYDRATION SOME DEHYDRATION SEVERE DEHYDRATION WHO/IMNCI/IAP : WHO/IMNCI/IAP Treatment Plan A: home therapy to prevent dehydration and malnutrition : Treatment Plan A: home therapy to prevent dehydration and malnutrition Children with no signs of dehydration need extra fluids and salt to replace their losses of water and electrolytes due to diarrhoea. If these are not given, signs of dehydration may develop. four rules ofTreatment Plan A: : four rules ofTreatment Plan A: Rule 1: give the child more fluids than usual Suitable fluids : two groups: Fluids that contain salt : • ORS solution • Salted drinks (e.G. Salted rice water or a salted yoghurt drink) • Vegetable or chicken soup with salt. Fluids that do not contain salt, such as: • Plain water • Water in which a cereal has been cooked • Unsalted soup • Yoghurt drinks without salt • Green coconut water • Weak tea (unsweetened) • Unsweetened fresh fruit juice. Slide 16: Unsuitable fluids Drinkssweetened with sugar, which can cause osmotic diarrhoea and hypernatraemia. Some examples are: • Commercial carbonated beverages • Commercial fruit juices • Sweetened tea. With stimulant, diuretic or purgative effects, for example: • Coffee • Some medicinal teas or infusions. Slide 17: How much fluid to give The general rule is: give as much fluid as the child or adult wants until diarrhoea stops. • Children under 2 years of age: 50-100 ml (a quarter to half a large cup) of fluid; • Children aged 2 up to 10 years: 100-200 ml (a half to one large cup); • Older children and adults: as much fluid as they want. Slide 18: Rule 2: Give supplemental zinc (10 - 20 mg) to the child, every day for 10 to 14 days Dose : infant – 0.5 mg/kg/day <6 mth – 10 mg/day >6 mth – 20 mg/day Preparations : zinconia 20mg/5ml zincovit 10mg/5ml Slide 19: Rule 3: Continue to feed the child, to prevent malnutrition Food should never be withheld Breastfeeding should always be continued. Aim - give as much nutrient rich food as the child will accept. Slide 20: Rule 4: take the child to a health worker if there are warningsigns of dehydration or other problems • Starts to pass many watery stools; • Has repeated vomiting; • Becomes very thirsty; • Is eating or drinking poorly; • Develops a fever; • Has blood in the stool; or • The child does not get better in three days. Treatment Plan B: oral rehydration therapy for children with some dehydration : Treatment Plan B: oral rehydration therapy for children with some dehydration Treatment Plan C: for patients with severe dehydration : Treatment Plan C: for patients with severe dehydration LAB INVESTIGATIONS FOR DIARRHOEA : LAB INVESTIGATIONS FOR DIARRHOEA Investigations are not routinely done in case of no or some dehydration I) STOOL: MICROSCOPY : low sensitivity & specificity a) leucocyte (>10/hpf )- Invasive diarrhoea b) hanging drop – V. cholera. c) culture & sensitive - persistant diarrhoea II) BLOOD TESTS a) CBC b) S. electrolyte c) BUN & creatinine Slide 24: ROLE OF ANTIBIOTICS Anti secretory agents : Anti secretory agents Racecadotril also known as acetorphan acts as a peripherally acting enkephalinase inhibitor. antisecretory effect—it reduces the secretion of excessive water and electrolytes into the intestine. Role is controvertial. Dose: 1.5mg/kg/dose up to 4 doses a day Duration : 5 days but not >7 days Adverse effects : vomitting , fever , hypokalemia , ileus , bronchospasm , skin rashes. Complications : Complications DEHYDRATION DYSELECTROLYTAEMIA PPT. OF MALNUTRITION PERSISTENT DIARRHOEA TOXIC ILEUS HUS DIC CORTICAL VIEN THROMBOSIS. ORAL REHYDRATON SOLUTION : ORAL REHYDRATON SOLUTION ORS -special combination of dry salts that, when properly mixed with clean water, can help rehydrate the body when a lot of fluid has been lost due to diarrhoea. Basis of ORS – Glucose linked absorption of sodium remains intact irrespective of etiology of diarrhoea. TYPES OF ORS FORMULATIONS : TYPES OF ORS FORMULATIONS Glucose based ORS Rice based ORS Low osmolarity ORS Home available ORS Mineral based ORS(zinc) Who ors composition : Who ors composition Composition of Resomal : Composition of Resomal Slide 33: What is NOT oral rehydration fluid? (1) Glucose water without salt (2) Fluids without starch/sugar (3) Fluids consumed in small quantity, e.g. tea Slide 34: THANK YOU You do not have the permission to view this presentation.
