For rapid fluid infusion, wide bore cannulae of short length will facilitate resuscitation.
Rate of flow can be affected by external factors like gravity, infusor devices and fluid viscosity.
Difficult cannulation can be aided by the use of high-frequency (8–5 MHz) ultrasound.
If direct cannulation fails, techniques like intra-osseous access, endotracheal access and venous cutdown can be used for drug administration.
