Venous access is the access to the bloodstream via the veins.Ā
Venous access is required forĀ
- Intravenous (IV) treatment administration such as medication or fluids (blood or rehydrating fluids) and nutrition if required
- Obtaining repeated venous blood samplesĀ
- As an access point for blood-based treatments such as dialysis or apheresis.Ā
– Apheresis involves removing whole blood and separating its individual components to remove one particular component. The remaining blood components are re-inserted into the patientās bloodstream.
Simple IV drug administration can be given as:
- An IV infusion where continuous blood levels are required such as antibiotics, antifungals, and pain-inhibiting drugs such as morphine and other opiates
- A ābolusā of medication over 1ā30 mins, however bolus IV administration is infrequently used and often restricted to emergency situations.Ā
- By administering a drug intravenously, a first-pass metabolism of the drug, where it is metabolised rapidly after administration is avoided. Therefore, a significantly higher concentration of the drug can reach the systemic circulation, allowing a more immediate effect.Ā
