Enteral Nutrition I: Orogastric and Nasogastric Feeding01:26

Enteral Nutrition I: Orogastric and Nasogastric Feeding

2.8K
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...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

1.9K
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.

Pharmacokinetics in Obese Patients: Drug Absorption and Distribution

430
Obesity significantly alters the pharmacokinetic processes of drug absorption and distribution, presenting unique challenges in medical treatment. The increased fat tissue and decreased lean muscle in obese individuals can significantly affect how drugs are absorbed into the body and distributed across different tissues. This alteration can lead to variances in the effectiveness and safety of medications, necessitating adjustments in dosing or drug selection for obese patients.One notable...

Summary
This summary is machine-generated.

Children undergoing tube weaning experienced significant reductions in body fat and anthropometry. Girls showed a greater initial decrease in subcutaneous fat, but both sexes had similar levels by the end of the program.

Area of Science:

  • Pediatric Nutrition
  • Body Composition Analysis
  • Gastroenterology

Background:

  • Long-term enteral feeding is common in children with specific medical conditions.
  • Tube weaning involves transitioning children from tube feeding to oral intake.
  • Changes in body composition during this transition require careful monitoring.

Purpose of the Study:

  • To evaluate changes in anthropometry and subcutaneous body fat in children during tube weaning.
  • To assess the effectiveness of a 3-week tube weaning program on body composition.
  • To document body fat distribution using subcutaneous adipose tissue topography (SAT-Top).

Main Methods:

  • A prospective cohort study with a pre-post-test design was employed.
  • The LIPOMETER, an optical device, measured subcutaneous adipose tissue (SAT) thickness.
  • Anthropometry and SAT-Top were measured before and after a 3-week tube weaning program in 30 children.

Main Results:

  • Both boys and girls showed significant decreases in anthropometry and subcutaneous body fat during tube weaning.
  • Girls experienced a larger initial reduction in fat mass (-30.7%) compared to boys (-18.4%).
  • By the end of the program, subcutaneous body fat levels were similar between sexes across all measured levels.

Conclusions:

  • Tube weaning leads to notable changes in children's anthropometry and subcutaneous body fat.
  • The findings provide baseline data for developing guidelines for safe and effective tube weaning.
  • Further research can explore long-term implications and individualized weaning protocols.
