A Clinical Trial Assessing the Safety, Efficacy, and Delivery of Olive-Oil-Based Three-Chamber Bags for Parenteral Nutrition

Here, we present a protocol for a study comparing the efficacy, safety, and delivery of olive-oil-based 3CB and soybean-oil-based CoB formulations in adults requiring parenteral nutrition. The results revealed that olive-oil-based 3CBs is non-inferior and well tolerated compared to soybean formulations.

Parenteral Anesthetics: Overview

Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.

Routes of Drug Administration: Parenteral

2023
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...

Drug Delivery: Parenteral Route
0 Views •
2024
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...

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,...

The formulation combines carbohydrates, amino acids, lipids, electrolytes, vitamins, and trace elements so that energy provision and tissue maintenance are addressed together. Because patients differ in nutritional status, fluid requirements, and metabolic condition, clinicians individualize the composition rather than treating the formulation as fixed. This coordination makes monitoring and subsequent adjustment essential during therapy.
Individualization helps align nutrient delivery with the patient’s ability to tolerate fluids and maintain metabolic balance. Clinicians consider the need for energy, amino acids, lipids, electrolytes, vitamins, and trace elements while accounting for the underlying inability to eat or absorb nutrients. The goal is to provide support without creating avoidable disturbances that require corrective changes.
Changes in fluid status, blood glucose, electrolyte measurements, or liver function can signal that the regimen needs review. These findings help clinicians evaluate whether the current nutrient and fluid delivery remains appropriate and whether complications may be developing. Ongoing assessment therefore connects laboratory and clinical observations with decisions about composition, monitoring intensity, and continuation.
Peripheral and central venous catheters are both routes for administering the sterile formulation, but the selected access route forms part of the overall clinical plan. The source material emphasizes that route selection occurs alongside individualized composition and monitoring rather than as an isolated decision. Regardless of access, clinicians must follow fluid status, glucose, electrolytes, and liver function.
Care begins by determining whether the gastrointestinal tract can adequately support digestion, absorption, or feeding. Clinicians then select an individualized sterile formulation containing the required nutrient categories, administer it through a peripheral or central venous catheter, and monitor fluid status, blood glucose, electrolytes, and liver function. Findings guide ongoing adjustment and later transition planning.
It may be considered when intestinal failure, severe malnutrition, or a prolonged inability to eat prevents adequate nutritional support through the gastrointestinal route. In these situations, the treatment helps maintain energy balance and tissue support while clinicians monitor tolerance and complications. As gastrointestinal or oral feeding becomes feasible, the care plan can guide transition away from intravenous support.
Monitoring shows whether the patient is maintaining appropriate fluid and metabolic balance while receiving intravenous nutritional support. Blood glucose and electrolyte results can identify disturbances, whereas fluid-status assessment and liver-function measurements provide additional information about tolerance and emerging complications. Together, these observations support regimen adjustments and help determine readiness for enteral or oral feeding.
