Parentral Nutrition: Centeral and Peripheral Parental Nutrition01:27

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,...

Parenteral Drug Delivery Systems: Injectables, Implants, and Infusion Devices

Parenteral drug delivery systems play a crucial role in modern therapeutics by enabling the direct administration of drugs into the systemic circulation, bypassing the gastrointestinal tract. These systems are particularly valuable for poorly absorbed oral medications that are unstable in the digestive environment or require rapid onset or sustained therapeutic levels. Delivery is achieved through intravenous, intramuscular, or subcutaneous routes, each selected based on the drug's properties...
Routes of Drug Administration: Parenteral01:25

Routes of Drug Administration: Parenteral

The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...
Enteral Nutrition I: Orogastric and Nasogastric Feeding01:26

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...
Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding01:15

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.
Nasointestinal Feeding
Nasointestinal feeding involves placing a tube through...
Drug Delivery: Parenteral Route01:29

Drug Delivery: Parenteral Route

The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

Area of Science:

  • Human Nutrition
  • Biochemistry
  • Clinical Medicine

Background:

  • Copper is an essential micronutrient vital for human health.
  • It acts as a cofactor for numerous metalloenzymes involved in diverse metabolic pathways.
  • Copper deficiency can lead to serious health issues like anemia and skeletal abnormalities.

Purpose of the Study:

  • To highlight the importance of copper as an essential nutrient.
  • To discuss the clinical manifestations of copper deficiency.
  • To establish recommended copper supplementation levels in parenteral nutrition.

Main Methods:

  • Review of existing literature on copper metabolism and requirements.
  • Analysis of balance studies to determine copper needs.
  • Consideration of specific patient populations, such as those undergoing parenteral nutrition.

Main Results:

  • Copper is indispensable for various metabolic processes due to its role in enzymes.
  • No definitive laboratory test exists to accurately measure body copper status.
  • Recommended daily copper intake for adults in total parenteral nutrition is 0.3 mg/day.
  • For infants and children, the requirement is estimated at 20 microg/kg body weight/day.

Conclusions:

  • Copper supplementation is critical in parenteral nutrition to avert deficiency.
  • Dosage recommendations are provided for adults, children, and infants.
  • Adjustments in copper supplementation are necessary for patients with cholestasis.
