Indication: It is commonly requested for patients who need rapid access for medication, rehydration, or in emergency situations.
Procedure: It requires strict aseptic technique and involves gathering equipment, identifying a suitable vein, inserting the needle/cannula, confirming placement ("flashback" of blood), securing the cannula, and flushing it to check patency.
Sizing: Cannulas come in different gauges (sizes, indicated by color) and the choice depends on what needs to be infused and the patient's veins.
Documentation: The procedure, including the date, time, location, and reason, is always documented in the patient's notes.
