The primary contraindications for intravenous injection include specific drug types and circumstances which can lead to adverse health outcomes.
Contraindications
Based on the provided reference, here's a breakdown of the key contraindications:
Specific Drug Types
- Oil-soluble drugs: These are not suitable for intravenous injection due to the risk of embolism. Oil-based substances can form globules in the bloodstream that can block blood vessels, causing significant harm.
Injection-Related Risks
- Rapid Injections: Administering intravenous medications too quickly can provoke dangerous cardiac arrhythmias (irregular heartbeats), which can be life-threatening.
Cardiovascular System Stimulants
- Strong Stimulants: Certain medications that strongly stimulate the cardiovascular system, such as adrenaline, pose a risk.
- Example: Adrenaline should only be administered intravenously in critical emergencies, like cases of drastically low blood pressure where the pulse is undetectable.
Table of Contraindications
| Contraindication | Explanation |
|---|---|
| Oil-Soluble Drugs | Risk of embolism due to oil globules blocking blood vessels. |
| Rapid Injections | Potential to cause cardiac arrhythmias. |
| Strong Cardiovascular Stimulants | Can be dangerous, requiring careful and limited use such as adrenaline for emergency situations. |
Additional Considerations
It's critical to note that these contraindications are not exhaustive. Medical professionals must always carefully evaluate each patient's individual situation and medication before administering an intravenous injection. Factors like patient allergies, existing medical conditions, and potential drug interactions must also be considered.
