What is important to keep in mind when evaluating a child for dehydration?

Percentage of weight lost is an objective measure


When evaluating dehydration, is it necessary to look at serum electrolytes?

No--serum electrolytes are NOT needed in mild dehydration. They are usually normal since most episodes of dehydration caused by diarrhea are isonatremic


When you have a child present w/ vomiting, what drug should you consider?

Ondansetron (zofran)

Almost all children who have been vomiting or are dehydrated can be treated w/ ORT (oral rehydration therapy)


ORT for a child who had DIARHHEA but is NOT dehydrated.

Continue to give age-appropriate diet

Children who are NOT dehydrated are least likely to take ORT b/c of the salty taste of the solution.


ORT for infant w/ diarrhea.

Continue to drink human milk or regular strength formula.


ORT for older child w/ diarrhea.

May continue to drink milk


How does ORT compare to IV therapy for rehydration children w/ mild-mod dehydration?

As effective

*less expensive and can be administered in many settings, including at home by family members


In a pt w/ diarrhea, does early refeeding w/ food after rehydration prolong diarrhea?


Milk may increase diarrhea but is NOT contraindicated (you can delay reintroduction a day or two)


Children who are severely dehydrated and in a state of shock need IV fluids. What should you give a child during a 1 hour period?

20 mL per kg of Normal Saline (NS)


Normal Saline with %5 dextrose (D5NS)


How can probiotics help children w/ acute diarrhea d/t viral gastroenteritis?

probiotics reduce the duration of diarrhea by about one day. Not yogurt


Is the routine use of antidiarrheal agents like opiates, bismuth subsalicylate, attapulgite recommended in infants and young children?


may have adverse SE


What is colic?

inconsolable crying (usually at a predictable time of day) accompanied by drawing up of legs and gaseous distension of the abdomen?


When does colic usually start and peak?

Colic starts by 3 weeks of age, and the peak occurs by 6 weeks of age

May include about 3 hours of crying a day.

The severity declines and by 3 months of age "normal" patterns are reestablished.


What should you do w/ a crying infant?

Rule out other causes for irritability and crying (especially otitis, another infections cause, intussusception, hairs around the penis, fingers, or toes)


What treatments for colic show NO BENEFITS?

hypoallergenic diet
no milk, egg, wheat or nut products
lactase enzymes
Carrying the infant more often
using car-ride simulators
decreasing infant stimulation
training the parents intensively in a behavioral approach


What percent of constipation in children is function?



What is retentive encopresis?

Inappropriate soiling w/ evidence of constipation and retention.

Children often soil small quantities of loose fecal matter several times a day put periodically pass very LARGE BMs.

May present w/ urinary complaints, abdominal pain or distention but PE is usually suggestive of constipation.


What is nonretentive encopresis?

inappropriate soiling w/out evidence of fecal constipation and retention


How should you treat retentive encopresis?

In 1-2 doses/day:
**Polyethylene glycol (PEG) (Miralax) 0.5-1 g/kg/day
-Milk of Magnesia, in a dosage of 1 to 3 mL per kg per day
-Mineral oil, in a dosage of 1 to 5 mL per kg per day
-Sorbitol, in a dosage of 1 to 3 mL per kg per day

*expect the tx to last TWICE as long as the duration of hte problem


What should you try if stool withholding leads to impaction?

Polyethylene glycol > child will have a bowel movement in 2-3 days.

Avoids the “trauma” of rectal manipulation.


What is recurrent abdominal pain syndrome?

prepubertal functional pain with two distinct peaks of frequency

Pain is:
unrelated to meals/acitivty/stool
not awakened by pain
HA, N, dizziness, fatigue

*Family Hx if often + for IBS, PE is often normal


When do the peaks associated w/ RAPS occur?

FIRST PEAK: occurs between five and seven years of age, with equal frequency in boys and girls and in 5 to 8 percent of children.

It is often attributed to the adjustment to parental separation when starting school.

SECOND PEAK: occurs between eight and 12 years of age and is far more prevalent in girls.


How do you tx RAPS?

Pain is real
emphasize that child must remain in school/normal activities


When does IBS rarely occur and what best characterizes it?

rarely before late adolescence

Intestinal dysmotility w/ intervals of diarrhea/constipation

Stress> flare-up sxs


What is most important for diagnosing a peptic disorder in a child?

positive family hx of PUD


A child presents w/ episodic nausea, abdominal pain and significant emesis, beginning during the night/early morning hours and lasting from six to 48 hours. The child has NO HEADACHE. The child has intervals of weeks to months with no symptoms or findings at all.

periodic syndrome or Abdominal migraine


What are common features/hx of children w/ abdominal migraines?

Family Hx of migraine

Autonomic Fx:
explosive diarrhea


A four-year-old boy presented with a three-day history of bloody diarrhea with no vomiting and a temperature up to 40。C (104。F). Over the previous 24 hours the child had had watery, bloody bowel movements every 20 minutes. His fluid intake consisted of soft drinks, and urination was infrequent. One other family member had non-bloody diarrhea. Na and Bicarb were both abnormal.

What is the most likely cause of this child's problem?

Bacterial infection cause by Shigella


A four-week-old female, breast fed twin born at 37 weeks of gestation had large, watery diarrheal stools five to six times per day for three to four days, with some vomiting. She was taking formula and no clear liquids. Her twin sister had a similar but less severe illness. The infant's neonatal course was normal. At two weeks of age she weighed 2.36 kg (5 lb, 3 oz). The patient was lethargic and weakly responsive, with cool extremities. Her skin turgor was decreased, and capillary-refilling time was about 3.0 seconds.

What is the most appropriate treatment in this case?

Bolus 20 cc/kg of NS

Continue breast feeding


A three-year-old boy presented with abdominal pain, fever and bloody diarrhea. No other family members were ill. The child had four to five bloody diarrheal stools per day, with no vomiting and decreased urination. Rare petechiae present.

What is the most likely pathogen?
E. Coli
Yersinia Enterocolitica

E. Coli



An 18-month-old girl presented with a three-day history of fever and frequent, bright red, bloody diarrheal stools. She was taking fluids, including some broth. There was no vomiting, and no other family members were ill. The child had recently traveled to Mexico. 104 temp.


Mexico, bloody diarrhea, stool culture negative


A five-year-old child presents with diarrhea. Just using prevalence as a tool, which of the following is the most likely pathogen?


Norwalk--epidemics (named after a town)


A 12-year-old child presents with diarrhea and is found to have white cells in his stool increasing the likelihood that he has a bacterial cause for his infection. Which of the following would be most likely using prevalence as a tool?

Campylobacter is most likley

White cells in the stool increase the likelihood that a bacterial infection is hte cause rather than a viral infection.

Campylobacter is the MC of the bacterial infections in children.


A three-week-old infant presents with increased crying for two days; inconsolable for “hours at a time”. Otherwise there has been no fever or vomiting. Intake has been slightly down – more fussy when breast feeding q2-3 hours (on demand). Her weight is appropriate.

What is the best intervention at this time?

Always check the extermities and penis in an irritable infant to look for a hair


A mother brings in her 3-yr-old child for diarrhea and incontinence of stool. Duration has been one week. He has had some mild problems with constipation but his mother states he reports large firm stools every 3-4 days. His most likely problem is:

Retentive encopresis

Retaining and "leaking around the log"


A mother brings in her 2-year-old child who has had diarrhea for three days. She has been able to get him to take fluids only. When he has had milk or solids, he has vomited. She has been giving him primarily chicken broth. Clinically he has a warm, "doughy" texture to his skin with little skin fold TENTING. He is also very droopy (your nurse thought him lethargic) but irritable when touched. His pulse is 160 and resp. is 35

These findings and hx are most compatible w/?

Hypernatremia--soft dough, won't tent as you would expect w/ dehydration
