The common sites for cannula insertion are the antecubital fossa (ACF) and the dorsum of the hand (DOH).
While various sites can be used for cannulation, the choice depends on factors such as the purpose of the cannula, patient condition, and clinician preference. Here's a breakdown:
-
Antecubital Fossa (ACF): This is the bend of the elbow and a frequently used site due to accessibility and prominent veins.
-
Dorsum of the Hand (DOH): The back of the hand offers several veins suitable for cannulation, especially when larger veins in the ACF are not accessible or suitable.
Other potential, less common, sites may include:
- Forearm veins: Veins along the forearm can also be used.
- Leg veins: In some situations, leg veins may be used, but this is less common due to increased risk of complications like deep vein thrombosis.
- Feet veins: Similar to leg veins, foot veins are typically avoided unless absolutely necessary.
The suitability of a particular site depends on factors such as vein size, visibility, and the patient's overall condition. Proper site selection is crucial for successful cannulation and minimizing complications.
