Enteral Nutrition I: Orogastric and Nasogastric Feeding01:26

Enteral Nutrition I: Orogastric and Nasogastric Feeding

2.5K
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

1.7K
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.
Nasointestinal Feeding
Nasointestinal feeding involves placing a tube...

Drug Delivery: Enteral Route01:18

Drug Delivery: Enteral Route

2.6K
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: Enteral01:18

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

1.6K
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

12.1K
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...

[IS EARLY ENTERAL FEEDING POSSIBLE?].

    Summary

    Early oral feeding post-surgery, once contraindicated, is now recommended by Enhanced Recovery after Surgery (ERAS) protocols. This approach stimulates gut motility and reduces complications, improving patient recovery after gastrointestinal procedures.

    Area of Science:

    • Gastroenterology and Surgical Recovery

    Context:

    • Traditional postoperative care prohibited early oral intake following gastrointestinal surgery due to concerns of paralytic ileus and anastomotic rupture.
    • This practice was based on the belief that the gastrointestinal tract required a prolonged period of rest for healing after open surgery.

    Purpose:

    • To evaluate the safety and efficacy of early oral feeding in the postoperative period, challenging conventional contraindications.
    • To assess the role of Enhanced Recovery after Surgery (ERAS) protocols in promoting early oral intake and improving patient outcomes.

    Summary:

    • Enhanced Recovery after Surgery (ERAS) protocols advocate for early oral intake, including preoperative supplementary water, after gastrointestinal tract anastomosis.
    • Early feeding is shown to stimulate intestinal motility, thereby decreasing postoperative complications.

  • Current evidence suggests ERAS protocols are safe for managing patients after large intestine surgery and are being explored for upper gastrointestinal procedures.

    • Impact:

    • Facilitates faster patient recovery and potentially reduces hospital stay duration.
    • Challenges long-held surgical dogma regarding postoperative feeding, paving the way for updated clinical guidelines.
    • Demonstrates the benefits of early nutritional support in enhancing gastrointestinal function and overall surgical outcomes.
