Study Notes

Digestive Tract Disorders

Diarrhea is a symptom resulting from issues with digestive, absorptive, and secretory functions. It's caused by abnormal intestinal water and electrolyte transport.
Globally, there are an estimated 1.7 billion episodes of diarrhea each year.
Diarrhea is defined as an increase in stool fluidity, volume, and number, relative to an individual's usual habits. Frequent passage of formed stools is not considered diarrhea.
Exclusively breast-fed babies often pass loose or semi-liquid stools, which is not considered diarrhea. Consistency is more important than frequency.
In Egypt, the seasonally adjusted incidence of diarrhea is 3.6 episodes per child under five years of age per year, representing a minimum of 30 million cases annually.
Diarrheal diseases are a significant cause of death in children worldwide, with a quarter of infant and childhood mortality linked to diarrhea.
In Egypt, about 15000 Egyptian infants and preschool children die yearly from diarrhea (about 42 deaths daily). 80% of these deaths occur within the first two years of life.

Seriousness of Diarrheal Disorders in Infancy

Limited intake and fluid loss during diarrhea can lead to:
- Acute dehydration
- Malnutrition (mothers may stop feeding their children during or after a diarrhea episode)

Incidence of Diarrhea

The peak incidence of diarrhea occurs between 6 months and 2 years of age.
This is due to:
- Declining maternal antibody levels
- Exposure to enteric pathogens through contaminated weaning food
- The habit of putting contaminated objects in the mouth while crawling.

Important Notes (N.B.)

Teething is not a cause of diarrhea. Diarrhea during teething is typically due to intestinal infection, and should be treated appropriately.
The life span of intestinal mucosal cells is 3-5 days. New cells replace damaged ones, so diarrhea is usually self-limiting, lasting 3-5 days.

Factors Predisposing to Diarrhea

Age: Younger children are more susceptible and experience more severe diarrhea.
Impaired health: Malnourished or immunocompromised children are more susceptible and tend to have more severe diarrhea.
Environment: Diarrhea is more common in areas with overcrowding, poor sanitation, inadequate food preparation and refrigeration facilities, and limited health education.

Types of Diarrhea

Diarrheal disturbances can involve:
- Stomach and intestines (gastroenteritis)
- Small intestine (enteritis)
- Colon (colitis)
- Colon and intestines (enterocolitis)

Classification of Diarrhea

Acute
Dysentery
Chronic

Acute Diarrhea

Defined as a sudden increase in frequency and change in stool consistency, usually self-limiting (14 days) and resolving without specific treatment if dehydration is avoided.

Causes of Acute Diarrhea

Infection and parasitic infestation, including:
- Bacteria (Salmonella, Shigella, Staphylococcus aureus)
- Viruses (Rotavirus, parvovirus)
- Parasites (Giardia lamblia, Entamoeba histolytica)

Associated Conditions

Upper respiratory tract infections
Urinary tract infections
Otitis media

Dietary Causes

Overfeeding
Introduction of new foods
Reinstatement of milk following a diarrheal episode
Osmotic diarrhea from excess sugar in formula or juice

Other Causes

Medications (antibiotics, laxatives)
Toxic ingestion (heavy metals like lead, mercury)
Functional issues (irritable bowel syndrome)
Other conditions (Hirschsprung enterocolitis)

Dysentery

A type of diarrhea characterized by visible fresh blood in the stool.
Other symptoms associated with dysentery include anorexia and damage to the intestinal mucosa.

Chronic Diarrhea

Defined as an increase in stool frequency and increased water content lasting more than 14 days.
Chronic nonspecific diarrhea (CNSD), also known as irritable colon, can affect children aged 6 to 54 months (4.5 years).

Causes of Chronic Diarrhea

Malabsorptive causes (e.g., lactose intolerance, pancreatic insufficiency)
Allergic causes (e.g., allergic gastroenteropathy, eosinophilic gastroenteritis)
Immunodeficiency (e.g., HIV, AIDS)
Inflammatory bowel disease (e.g., ulcerative colitis)
Endocrine causes (e.g., hyperthyroidism, congenital adrenal hyperplasia)
Motility disorders (e.g., Hirschsprung disease)
Parasitic infections (e.g., ascaris, giardia)
Other causes (e.g., radiation enteritis, abdominal tumors)

Complications of Diarrhea

Dehydration
Malnutrition

Dehydration

A consequence of watery diarrhea, caused by loss of water and electrolytes in liquid stools and vomiting.
Fever can worsen dehydration by causing additional water loss.
Untreated dehydration can lead to hypovolemia, cardiovascular collapse, and death.

Types of Dehydration

Isotonic (or isosmotic/isonatremic) – electrolyte and water loss are balanced. Water and sodium are lost in approximately equal amounts.
Hypotonic (or hyposmotic/hyponatremic) – electrolyte deficit exceeds water deficit. The serum becomes hypotonic.
Hypertonic (or hyperosmotic/hypernatremic) – water loss exceeds electrolyte loss. It's usually caused by a disproportionately larger loss of water, or a larger intake of electrolytes.

Nursing Management of Diarrhea

Nursing assessment includes:
- Taking the child's history (age, sex, socioeconomic background)
- Measuring weight and temperature
- Assessing the degree of dehydration
- Identifying characteristics of the stool
- Assessing the child's ability to drink and if thirst is present
- Determining if vomiting, fever or other problems are present (e.g., cough, otitis media)
Assessing the child's last urination and feeding practices
Reviewing episodes of illness, any treatments given (ORS, drugs), review of vaccination history.

Assessment of Dehydration

Classification of the degree of dehydration based on physical signs.
- Mild (normal signs)
- Moderate (two or more concerning signs)
- Severe (two or more concerning signs)

Other Signs of Dehydration

Anterior fontanelle (normal depression).
Mucous membranes of the mouth and tongue (moist and normal).
Tears (present in mild dehydration): absent in severe dehydration.
Radial Pulse: becomes more rapid as dehydration increases, and weak in severe dehydration.
Extremities: skin becomes cool and moist in severe dehydration, and the nail beds may be cyanosed.
Breathing: rapid deep breathing signals acidosis.

Weighing

Crucial for estimating fluid requirements during initial rehydration.
Weight should be taken to the nearest 50-100 grams and recorded at the beginning and end of rehydration.

Diagnostic Evaluation of Dehydration

Assessing the degree and type of dehydration (based on physical assessment and pathophysiology).

Specific Signs of Dehydration

Specific physical signs (other than general symptoms).
Initial plasma sodium concentration
Serum bicarbonate concentration (CO2)
Any associated electrolyte and acid-base imbalances.

Therapy of Dehydration

Oral rehydration therapy (ORS) is an effective method comprising a mixture of water, glucose, and electrolytes, used to correct and prevent dehydration. Increasing the glucose concentration (2%) promotes sodium absorption, but can also cause osmotic diarrhea if too high.

Composition of ORS

ORS solutions with specific amounts of sodium chloride, tri-sodium citrate, potassium chloride and glucose

N.B. (For ORS)

Using citrate improves the shelf-life and lowers the cost of ORS.
Tap water is used to dissolve the mixture and doesn't require boiling.
It can be administered by cup, spoon or by nasogastric tube in situations where the patient can't drink (but not in shock), or if repeated vomiting or insufficient improvement of dehydration using other methods.

Intravenous Rehydration

Used in cases with severe dehydration.
Also used when oral rehydration is unsuccessful due to fatigue, coma, uncontrollable vomiting, unimproved dehydration signs, or issues with glucose malabsorption.

Treatment Plan for Diarrhea

A stepwise approach for managing diarrhea in various severity levels (Plan A, B, and C)
- Plan A (mild dehydration): at home, using homemade fluids.
- Plan B (moderate dehydration): at an outpatient dehydration center, providing oral rehydration solution (ORS)
- Plan C (severe dehydration): in a hospital, using Intravenous fluids.

Feeding During and After Diarrhea

During diarrhea: feed the child as much as desired.
Offer food every 3-4 hours.
Small, frequent feedings are better than less frequent, large meals.
Offer easily digestible foods as they aid in intestinal absorption.
Gently encourage children with anorexia to eat.
Increase meal portion sizes slightly after diarrhea subsides for 2 weeks in normal children and a longer period in malnourished children.

Advantages of Feeding During Diarrhea

Maintaining body weight and supporting growth
Protecting gut mucosa, improving digestive enzyme production, and maintaining absorptive capacity
Promoting faster recovery

Easily Digestible Foods During Diarrhea

Enhancing intestinal salt and water absorption via organic molecules.
Studies show continued feeding hastens recovery from a diarrheal episode.

Assessment of Rehydration Progress

Assessing the patient hourly for progress in recovery.
Indicators of a satisfactory response include:
- Return of a strong radial pulse.
- Improved consciousness level.
- Ability to drink.
- Improved skin turgor
- Passage of urine

Drug Therapy in Diarrhea

Avoid giving anti-diarrheal, anti-motility, and anti-emetic drugs. ORS solution and continued feeding are usually sufficient for recovery.

Substances to Avoid

Substances like bismuth and chalk mixtures modify stool characteristics but do not resolve issues with stool frequency, amount or water content.

Prevention of Diarrhea

Breastfeeding promotion
Improved weaning practices
Proper water use for hygiene and drinking
Personal hygiene
Latrine use
Measles vaccination
