Study Notes
Injection Routes
- There are several routes for injecting medications, each with its own advantages and disadvantages
- The choice of route depends on the type of medication, the desired rate of absorption, and the patient's condition
Intramuscular Route
- Injects medication into well-perfused muscle, providing rapid systemic action
- Can absorb fairly large doses, from 1 ml in the deltoid to 5 ml in the ventrogluteal site
- Sites for intramuscular injections include deltoid, dorsogluteal, ventrogluteal, and vastus lateralis
Subcutaneous Route
- Used for slow, sustained absorption of medication, up to 1-2 ml injected into subcutaneous tissue
- Often used for medications that require a slow, steady release, such as insulin or anticoagulants
- Relatively pain-free, with sites suitable for frequent injections
Intradermal Route
- Potential complications include infection, incorrect location of injection, pain, anaphylaxis, nerve damage, and hematoma
Injection Techniques
- Z-Tracking technique is used for intramuscular injections
- Needle angle is important for subcutaneous injections, typically 45 degrees
- Factors that affect the injection process include the needle, chemical composition of the drugs, technique, speed of injection, and volume of the drug
Prescription and Administration
- The prescription chart should be checked to confirm drug, dose, date, time of administration, route, and method of administration
- The prescription should also include diluent as appropriate, validity of prescription, and signature of prescriber
Intravenous Route
- Can be peripheral (short-term) or central (long-term)
- Risks and side effects include inflammation, drug irritation, bruising, drug extravasation, infection, and central line issues
- Treatment and healing time for blown veins involve resting the affected limb, avoiding strenuous activity, and applying cold packs to reduce swelling
Needle Stick Injury
- If a used needle pierces the skin, follow first aid advice immediately, including encouraging the wound to bleed, washing with soap and water, and applying a waterproof plaster or dressing
- In some cases, antibiotic treatment, vaccination against hepatitis B, or treatment to prevent HIV may be necessary
