TREATMENT PLAN A
4 Rules of home treatment
1.Give extra fluid-
Breastfed frequently,
Give one or more : ORS solution, food based fluids (such as soup,rice water and yoghurt drinks), clean water
Teach the mother how to mix and give ORS.Give the mother 2 packets of ORS to use at home.
Show the mother how much fluid to give (After each loose stool and between them) in addition to the usual fluid intake:
Up to 2 years : 50-100 ml 2 years or more:100-200 ml >10 years: as much as wanted
![Page 18: Acute Diarrhoea](https://reader033.vdocuments.mx/reader033/viewer/2022061214/549cf000ac7959b02a8b4861/html5/thumbnails/18.jpg)
Tell the mother to:
Give frequent small sips from cupIn case of vomiting: Wait 10 min.then continue but slowly,Continue giving extra fluids until the diarrhoea stops
2.Give Zinc Supplements:
Tell the mother how much zinc to give: < 6 months (dose 10 mg/day): ½ tab x 14 days >6 months (dose 20 mg/day): 1 tab x 14 days
3. Continue feeding
4. Tell the mother when to return

TREATMENT PLAN B
• Determine amount of ORS over 4 hour period:
75 ml/kg body • If the child wants more ORS then give more• For infants < 6 months (not breastfed): give 100-200 ml clean water also
Age (months)
< 4 4-12 12-24 24-60
Weight (kg)
<6 6-<10 10-<12 12-19

Tell the mother to:
Give frequent small sips from cup In case of vomiting: Wait 10 min.then continue but slowly, Continue giving extra fluids until the diarrhoea stops
After 4 hours
Reassess as per assessment chart and treat accordingly (Plan A,B or C)
If the mother must leave before completing treatment:• Show her how to prepare ORS solution at home• Show her how to prepare ORS to give to finish 4 hr treatment • Also give 2 packets ORS
Explain the 4 rules of home treatment:
1.Give extra fluid 2.Give zinc supplements 3.Continue feeding 4.When to return
![Page 21: Acute Diarrhoea](https://reader033.vdocuments.mx/reader033/viewer/2022061214/549cf000ac7959b02a8b4861/html5/thumbnails/21.jpg)
TREATMENT PLAN C Can you give the IV fluid immediately? YES
If the child can drink, give ORS orally while the drip is set up.
Age First give 30ml/kg in
Then give 70 ml/kg in
< 12 months 1 hour* 5 hour*
12 months - 5 years
30 min.* 2 ½ hours*
* Repeat once if radial pulse is still very weak or not detectable
•Reassess the child every 1-2 hours. If hydration status is not improving give the IV drip more rapidly
•Also give ORS (5 ml/kg/hour) as soon as the child can drink.
•Reassess an infant after 6 hours and child after 3 hours: Decide the treatment
![Page 22: Acute Diarrhoea](https://reader033.vdocuments.mx/reader033/viewer/2022061214/549cf000ac7959b02a8b4861/html5/thumbnails/22.jpg)
Can you give the IV fluid immediately? NO
Is IV treatment available nearby (within 30 min.) YES
Refer urgently to hospital for IV treatmentRefer urgently to hospital for IV treatment
(If the child can drink. Provide the mother with ORS solution and show her how to give frequent sips during the trip)
Is IV treatment available nearby (within 30 min.) NO
Are you trained to use a nasogastric tube for rehydration? YES
Start rehydration (ORS solution) by tube/mouth : 20 ml/kg/hour for 6 Start rehydration (ORS solution) by tube/mouth : 20 ml/kg/hour for 6 hours.hours.
Reassess the child every 1-2 hours
•If vomiting or increasing abdominal distension, give the fluid more slowly
•If hydration status is not improving after 3 hours, send the child for IV therapy
•After 6 hours, reassess the child and treat (A,B or C)

FOLLOW UP
• Follow up after 2 days in dysentery, after 5 days in acute diarrhoea
• Return immediately if the child develops: Many watery stools, Repeated vomiting, Fever, Poor or unable to drink and eat/ breastfeed, Blood in stool

Benefits of citrate ORS over bicarbonate ORS
1.Trisodium citrate made the ORS stable
2. Resulted in less stool output
Benefits of low-osmolarity ORS over normal ORS
1.Osmolarity reduced to avoid the adverse effects of hyper-tonicity
2.Need for unscheduled IV management reduced 33% in children with hypo-osmolar ORS
2.Stool output and vomiting decreased
3.India-first country in the world to launch new ORS since June 2004

Home made ORS
1 tsp table salt + 4 heaped tsp sugarin 1 litre of water
SUPER ORS
Amino acid based ORS
Amino acids (Alanine, Glycine co-transport the Na+) are used in place of glucose
Powder of boiled rice (50 mg/L) can be used in place of amino acids
Decrease purging rates and improve absorption

NUTRITIONAL MANAGEMENT OF DIARRHOEA
1.Continue feeding
2.Energy dense foods should be given: Khichri , rice with milk, curd and sugar, mashed banana with milk, mashed potatoes and lentils
3.Foods with high fibre content should be avoided
4.During recovery, an intake of at least 125% of normal requirement should be attempted
![Page 39: Acute Diarrhoea](https://reader033.vdocuments.mx/reader033/viewer/2022061214/549cf000ac7959b02a8b4861/html5/thumbnails/39.jpg)
National diarrhoea diseases control programme
1.Short term: Appropriate clinical management
-ORT-Appropriate feeding-Chemotherapy
2.Long term
a. Better MCH practices
-Maternal nutrition-Child nutrition: breast feeding, proper weaning, supplementary feeding
![Page 40: Acute Diarrhoea](https://reader033.vdocuments.mx/reader033/viewer/2022061214/549cf000ac7959b02a8b4861/html5/thumbnails/40.jpg)
b. Preventive strategies
