Continuous Peripheral Nerve Block
Continuous Peripheral Nerve Block (CPNB);
when the anesthetic medication is delivered close proximity to a peripheral nerve that controls the organ that been treated by the surgery.
The pain being
anaesthetizing by continuously delivery of anesthetic medication near to the peripheral nerve.
Efficient nerve block is obtained once the medication is surrounding over the nerve cord at at-least 180° of its circumference along a segment of about 10 mm long and profound nerve block is obtained once the medication is fully (360°) surrounding the nerve cord at segment of about 10 mm long - a "shut off" the Peripheral nociceptors is obtained
The femoral nerve is fully surrounded by the LA "pancake" like
The LA covering about half of the circumference of the femoral nerve; efficient the pain blockage is achieve (but not profound blockage)

B. Factors Influencing on the Therapy Efficiency
> Position of the catheter
> Medication: type, concertation
2. Continuous Basal Flow
> Flow rate
> Bolus volume
> Velocity rate
