Assessment of dehydration in SAM child
• Dehydration tend to be over diagnosed and its severity often overestimated in SAM child.
• usual sign of dehydration like skin pinch, sunken eye ball ,appearance of child is no use in SAM child. because
• Loss of elasticity of skin, and sunken eye may be either due to loss of subcutaneous fat in sam child.
• Irritability, lethargic, unconscious child may be due to hypoglycemia, infection and other complication of SAM.

• Oral mucosa feel dry• Presence of thirst, hypothermia, week pulse
and oliguria, absent tear• Its safe to assume that all SAM child with
watery diarrhea have some dehydration

• Basis of solution • SAM children are deficient in potassium
and have very high level of sodium, normal ores solution is dangerous for them.
• They need solution which contain less sodium and more potassium.
• These pt. are also deficient in in other minerals like magnesium, copper, zinc, and these minerals are added
ReSoMal
![Page 10: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/10.jpg)
ReSoMal• ReSoMal contains a mixture of salts and minerals to
correct deficiencies of potassium, magnesium, zinc and copper and to address high levels of sodium in children with SAM.
• It is supplied as powder in sachets. Previously, one sachet needed to be reconstituted by adding 2 liters of boiled water to the content of each sachet, producing thereafter 2 liters of rehydration solution.
• The reconstituted solution has to be consumed immediately or used within 24 hours if stored in a refrigerator.
• a quantity of reconstituted ReSoMal was being wasted.
![Page 11: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/11.jpg)
• In order to resolve this problem, discussion was initiated in 2010 between UNICEF Programmed Division, Supply Division, Regional Offices, nutritionists working in in-patient centers and suppliers - and concluded that the sachet sizes should be reduced.
• It was agreed that the optimal volume of the solution should be 1 liter. Hence, it was decided to reduce the sachet sizes by 50 per cent.
• New sachets must be reconstituted by adding 1 liter of boiled, cooled water, which will result in 1 liter of liquid ReSoMal.

Some dehydration• Dehydration should be corrected slowly over
period of 12 hour.• ReSoMal should be given orally or by nasogastric
tube at 5 ml/kg every 30 minutes for first 2 hours• Then 5-10 ml/kg every hour for next 4-10 hour.• Exact amount depend on how much child want,
volume of stool loss and whether child is vomiting• Ongoing stool losses should be replaced with
approximately 5-10 ml/kg ors after each watery stool
![Page 14: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/14.jpg)
• BF should be continued during the rehydration phase.
• Refeeding must be started with starter f-75 formula within 2-3 hr. of starting rehydration.
• The feed must be given on alternate hours(eg.hours 2, 4, 6) with ors (hr. 1, 3, 5).
• Once rehydration complete feeding must be continued and ongoing losses replaced with ors.

• Monitor every ½ hourly for first 2 hour and then every hours for next 4-10 hours.
• Monitor pulse rate, respiratory rate ,oral mucosa, urine frequency or volume, and frequency of stool and vomiting.
• Decrease in heart rate and respiratory rate( if initially increased ) and increased in urine output indicate rehydration is proceeding.
• Return of tear, a moist oral mucosa, less shunken eye and fontanelle improved skin turgor also indicate rehydration.

Scenario A Clinical assessment of dehydration
This 2 year old male child was brought to the emergency room with diarrhoea for 6 days. He had angular stomatitis, peri-anal ulceration, weighed 7.0 kg and the MUAC was 10.2 cm.
His hands were cold, pulse weak and fast and skin pinch went back very slowly. The resident doctor gave 140ml of normal saline by rapid IV infusion but his condition deteriorated.
![Page 19: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/19.jpg)
Questions
• Q1: What important condition needs to be recognised in this child?
• Q2: Was the doctor’s management correct?
• Q3: List 2 pathophysiological mechanisms in this condition that affect fluid management.
![Page 20: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/20.jpg)
Answer 1
• The child has severe acute malnutrition: SAM with shock
![Page 21: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/21.jpg)
ANSWER 2• The doctor’s choice of IV normal saline,
amount of fluid and rapidity of given IV fluid were all incorrect and may have caused the child’s deterioration.
• The IV fluid of choice (in order of preference) according to availability are:–Ringers lactate with 5% dextrose–Half-nomal saline with 5% dextrose–Half-strength Darows solution with 5%
dextrose–Ringers lactate
![Page 22: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/22.jpg)
• Amount of fluid–Give IV fluid 15ml/kg over 1 hour
• Monitor pulse and breathing rate at the start and every 5-10 minutes
• If there is improvement (pulse and respiratory rate fall), repeat IV fluid 15ml/kg over 1 hour
• Then switch to oral or nasogastric rehydration with Resomal 5-10 ml/kg/hr
ANSWER 2
![Page 23: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/23.jpg)
ANSWER 3• The pathophysiological mechanisms that affect fluid
management are:
1. Although plasma sodium may be very low, total body sodium is often increased due to – increased sodium inside cells– additional sodium in extracellular fluid if there is
nutritional oedema– reduced excretion of sodium by the kidneys
2. Cardiac function is impaired in SAMThis explains why treatment with IV fluids can result
in death from sodium overload and heart failure.
![Page 24: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/24.jpg)
CONCLUSION
• The correct management is reduced sodium oral rehydration fluid (ORF; e.g. ReSoMal) given by mouth or naso-gastric tube if necessary.
• The volume and rate of ORF are much less for malnourished than well nourished children (see next slide)
• IV fluids should be used only to treat shock in children with SAM who are lethargic or have lost consciousness!
![Page 25: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/25.jpg)
How can we prevent diarrhoeal disease?
This involves intervention at two levels:• Primary prevention (to reduce disease transmission)
– Rotavirus and measles vaccines– Handwashing with soap– Providing adequate and safe drinking water– Environmental sanitation
• Secondary prevention (to reduce disease severity)– Promote breastfeeding– Vitamin A supplementation– Treatment of episodes of AD with zinc

Persistent diarrhea
![Page 27: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/27.jpg)
Definition•Diarrhea that starts as an acute episode and last at least 14 days is sad to be persistant
![Page 28: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/28.jpg)
Etiology• Persistent infection• PEM• Malabsorption of carbohydrate and
fat due to combination of malnutrition and enteric infection
• Infrequently, dietary protein intolerance
![Page 29: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/29.jpg)
Complication• Malnutrition and
worsening of malnutrition• dehydration
![Page 30: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/30.jpg)
INVESTIGATION• Following ix recommended in each pt of PD 1. Examination of stool
macroscopic, , consistency, presence of mucus and blood
2. microscopic-pus cell, RBC, parasites, ova, cyst, trophozoites of E.histolytica, G.lamblia
3. Stool culture for salmonella shigella4. Stool for reducing sugar carbohydrate
intolerance5. Stool ph. carbohydrate intolerance

Dietary management• Diet A (reduced lactose diet)• Diet B (lactose free diet with
reduced starch)• Diet C (monosaccharide based
diet)
![Page 34: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/34.jpg)
Diet A• Basis of diet A1. In PD due to persistent infection or reinfection of same and
different microorganism2. And due to malnutrition there is damaged to small bowel
epithelium. Brush border of small bowel epithelium contain disaccharides.
3. In the absence of these enzyme disaccharide are not hydrolyzed in simple sugar and reach unchanged in to the lower gut where these draw water from gut wall throw osmosis.
4. Unabsorbed sugar fermented by gut bacteria leading to production H2, methane, co2,these gas cause abdominal distention and frothy character of stool.
![Page 35: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/35.jpg)
Diet A1. Infant age less than 6 month• Encourage exclusive breast feeding• Reestablish lactation• If only animal milk must be given,
replace it with curd and lactose free milk formula(give with a cup and spoon)
• If required, cooked rice can be mixed with milk/curd/lactose free formula
![Page 36: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/36.jpg)
Diet A #• Limit daily intake of milk 50-60 ml/kg• Lactose not more than 2 gm/kg day• To reduced lactose concentration in
animal milk do not dilute it reduced energy density critically.
• Milk can be mixed with cereals• Start feeding as soon as the child can eat• Offer 6-7 feed per day
![Page 37: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/37.jpg)
• Total energy intake of 110 kcal/kg to begin with increase energy intake steadily up to 150 kcal/kg over next two week

Advantage of diet A• Well tolerated• Highly palatable• Consumed in large quantity• Provide adequate calories, good
quality proteins and micronutrient• Results in faster weight gain
![Page 39: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/39.jpg)

Diet B
Lactose free diet with reduced starch
![Page 42: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/42.jpg)
Diet B• Basis for diet B• some children do not respond well to initial low
lactose diet. they have impaired digestion of starch and other disaccharides other than lactose.
• therefor not only milk is eliminated but starch is reduced and partially substitute by glucose.
• Substituting only part of the cereal with glucose increase the digestibility but at the same time does not cause very high osmolarity
![Page 43: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/43.jpg)
Diet B #• Milk free diet (Lactose free)• Carbohydrates provided as a
mixtures cereals and glucose• Milk protein is replaced by chicken,
egg, and protein hydrolysate
![Page 44: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/44.jpg)

Diet c• Basis for diet C• Over all 80-85% pt. with severe persistent diarrhea
will recover with sustained wt. gain on the initial diet A or the second diet B.
• Some pt. may not tolerate moderate intake of cereal in diet B
• These children are given the third diet C.• Diet C contain only glucose and a protein source as
egg white or chicken or protein hydrolysates.• Energy density is increased by adding oil to the diet
![Page 47: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/47.jpg)

Supplemental vitamins and minerals
• About twice the RDA should be given to all children for at least 2-4 week.
• Iron supplements should be given only after diarrhea ceased.
• Provide Vitamin A(as a single large dose) and zinc ,these have been show effect recovery from persistent diarrhea.
• is• and minerals

Other recommendation
• Magnesium sulphate 50% : 0.2ml/kg/dose twice a day for 2-3 days
• Potassium 5-6 meq/kg/day orally or i.v. as a part of initial stabilization period.
![Page 53: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/53.jpg)
Indication for change from the initial diet A to diet B or diet B to diet C
• In the absence of initial or hospital acquired infection, the diet should be changed when treatment failure, defined as
1. A marked increased in stool frequency usually more than 10 watery stool/day any time after initiating treatment.
2. Return of sign of dehydration any time after initiating treatment.
3. Failure to established weight gain by day 7.4. Unless sign of treatment failure occur earlier each
diet should be given for minimum period of 7 days
![Page 54: Dehydration in sam child and persistant diarrhea](https://reader031.fdocuments.us/reader031/viewer/2022012402/58798d371a28ab95318b4eb5/html5/thumbnails/54.jpg)
Resumption of regular diet after discharge
• Children discharge on diet B should be given small quantities of milk as apart of mixed diet after 10 days.
• If they have no sign suggestive of lactose intolerance (diarrhea, vomiting, abdominal pain, abdominal distention, excessive flatulence)
• milk can be gradually increased over next few days
• A normal diet appropriate for age can be resumed over next week.

Recommendation for antimicrobial therapy
• High fever• Presence of blood and mucus in stool• Associated systemic infection• Severe malnutrition• Severe abdominal pain • Recent use of antibiotics or hospitalized
patients• Immunocompromised patients, including
(HIV)
