Summary
Subcutaneous injection techniques vary, increasing skin complication risks. Research shows subcutaneous fat amount and needle length are crucial for effective drug delivery, but evidence for optimal technique remains weak.
Area of Science:
- Nursing Practice
- Pharmacology
- Medical Education
Background:
- Inconsistent advice on subcutaneous injection techniques is provided in nursing education and patient materials.
- Varied self-administration methods increase the risk of injection-related skin complications.
- Nurses play a key role in administering medications and educating patients on injection techniques.
Purpose of the Study:
- To identify the scientific basis for optimal subcutaneous injection techniques.
- To determine the best practices for administering subcutaneous injections for correct dosage and site, minimizing complications.
Main Methods:
- A systematic review of three databases was conducted.
- Articles were screened at the abstract level and underwent independent quality assessment.
- Included studies focused on dose, location, and complications of subcutaneous injections.
Main Results:
- 38 articles were assessed, revealing heterogeneous study designs and limited information on technical performance.
- The scientific foundation for subcutaneous injection technique is currently weak.
- Subcutaneous fat volume and appropriate needle length are critical factors for successful drug absorption.
Conclusions:
- Further research is necessary to establish evidence-based guidelines for subcutaneous injection techniques.
- Developing standardized, effective subcutaneous injection protocols is essential.

01:28Parenteral 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...
01:29Drug 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...

01:21Drug Accumulation During Multiple Dosing: Repetitive IV Injections
Calculating drug dosage and accumulation in multiple-dose regimens is crucial for achieving therapeutic efficacy while avoiding toxicity. This involves determining the plasma drug concentrations over time to optimize dosing schedules. The principle of superposition is fundamental in this process, allowing for the prediction of drug concentration in plasma following multiple doses based on single-dose data.The principle of superposition asserts that the plasma concentration-time curves from...
01:25Routes 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...

01:27Insulin Formulations: Types and Delivery
Insulin preparations are categorized by their duration of action into short-acting and long-acting types. Two strategies are used to modify insulin's absorption and pharmacokinetic profile: slowing the absorption post-subcutaneous injection, or altering human insulin's amino acid sequence or protein structure. These changes retain the insulin's ability to bind to the insulin receptor, but alter its behavior in solution or after injection.
