Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Drug Dosing: Infants and Children

Drug Dosing: Infants and Children

Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Suctioning the Nasopharyngeal Airway

Suctioning the Nasopharyngeal Airway

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Pyloric Obstruction

Pyloric Obstruction

Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...

Summary

This summary is machine-generated.

This study found that using a "chaser" — a preferred food or drink — effectively reduced packing, a feeding disorder where children hold food in their mouths. This intervention shows promise for improving mealtimes for children with feeding difficulties.

Area of Science:

Pediatric feeding disorders
Behavioral interventions
Childhood nutrition

Background:

Packing, characterized by oral retention of food, is a common feeding disorder in children.
This behavior can lead to nutritional deficits and mealtime challenges.
Effective interventions are needed to address packing and improve oral intake.

Purpose of the Study:

To investigate the efficacy of a chaser strategy in reducing solid food packing in children with feeding disorders.
To evaluate the impact of immediate or delayed chaser presentation on packing behavior.

Main Methods:

A case study approach was used with 3 children diagnosed with feeding disorders exhibiting packing behavior.
A chaser (a preferred liquid or solid) was introduced immediately or after a 15-second delay following each bite of solid food.
The frequency of packing behavior was measured during the intervention phases.

Main Results:

The chaser intervention was effective in decreasing packing behavior for all 3 participating children.
Consistent swallowing of the chaser was observed across participants.
The strategy demonstrated a positive impact on managing oral food retention.

Conclusions:

The use of a chaser is a clinically viable and effective strategy for reducing packing behavior in children with feeding disorders.
This intervention offers a practical approach for therapists and parents to manage feeding difficulties.
Further research is warranted to explore variations in chaser type, timing, and generalization of the effect.
