length: ½- 4”
gauge: 12-30 (18 ideal)
arterial/ venous cannula
(IV needles)
used to place a catheter into vessel
Arterial:
- obtain blood gases
- monitor BP
Venous:
- introduce fluids into system
- introduce monitoring catheters
heparin needle
round tipped
used to flush
- attached to syringe to irrigate open arteries
irrigation needles
small diameter cannulated tube attached to plastic needle hub for placement on a syringe
used during micro and eye surgery
veress needle
attached to co2 tubing
facilitate delivery of gas
introduced percutaneously into abd
biopsy needle
obtain tissue samples for biopsy
aspirate fluid from cysts
obtain cells from breast lesions, or other shallow tissues
five types of biopsy needles
