Enteral Nutrition I: Orogastric and Nasogastric Feeding01:26

Enteral Nutrition I: Orogastric and Nasogastric Feeding

3.1K
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

2.0K
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 Delivery: Enteral Route01:18

Drug Delivery: Enteral Route

2.9K
The enteral drug administration involves three primary routes: oral, sublingual, and buccal. Oral ingestion is the most prevalent, safe, economical, and convenient method for drug administration. However, it has certain drawbacks, including limited absorption due to the drug's low water solubility or poor membrane permeability, possible emesis from GI mucosa irritation, destruction of drugs by digestive enzymes or low gastric pH, and irregular absorption along with food or other drugs.

Routes of Drug Administration: Enteral

8.4K
Medications can be administered through the enteral route using liquids, capsules, or tablets.
Enteral administration involves drug administration via the mouth in two ways: orally or sublingually.
Unlike sublingually drugs, drugs that are taken orally pass through the gastrointestinal (GI) tract and get metabolized by the liver. Once metabolized, the drug is absorbed into the systemic circulation, reaching different body parts via the bloodstream. However, while passing through the stomach,...

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

2.0K
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,...

Endotracheal Intubation I: Procedure

13.9K
Endotracheal or ET intubation is a critical medical procedure used to secure a patient's airway, often in acute respiratory distress, apnea, upper airway obstruction, ineffective clearance of secretions, high risk for aspiration, or during general anesthesia.
The ET tube comprises various components, including a standard adaptor to attach a bag-valve-mask (BVM) or ventilator, a cuff, a pilot balloon, and radiopaque markings along its length to measure the insertion distance. The tube sizes...

Summary

Tube feeding, including nasogastral tubes and percutaneous endoscopic gastrostomy (PEG) tubes, is a vital therapy for patients unable to eat. Despite potential complications, the benefits of enteral nutrition significantly outweigh the risks.

Area of Science:

  • Clinical Nutrition
  • Gastroenterology
  • Medical Devices

Background:

  • Tube feeding is a crucial medical therapy, manageable in outpatient settings.
  • Nasogastral, nasojejunal, and percutaneous endoscopic gastrostomy (PEG) tubes are common for enteral nutrition.
  • Portable nutrition pumps facilitate delivery for patients with inadequate oral intake.

Purpose of the Study:

  • To review the indications, methods, and management of tube feeding.
  • To highlight the role of enteral nutrition in various clinical scenarios.
  • To discuss potential complications and the overall benefit-risk profile of tube feeding.

Main Methods:

  • Review of current clinical practices in enteral nutrition.
  • Discussion of different types of feeding tubes and delivery systems.

  • Analysis of nutritional formulations and patient-specific adjustments.

    • Main Results:

    • Enteral nutrition is indicated when oral intake is insufficient or impossible, especially post-intervention.
    • Commercially available, standardized formulas are widely used, with tailored compositions available.
    • Potential complications include tube issues (dislocation, obstruction) and feeding-related problems (hyperglycemia, diarrhea, aspiration).

    Conclusions:

    • Tube feeding is an essential component of nutritional support in diverse medical conditions.
    • The benefits of enteral nutrition generally surpass the associated risks.
    • Careful management and monitoring are key to optimizing outcomes and minimizing complications.
