IV Catheter Sites & Placement (ASAN002/11) Flashcards
Intravenous Site Selection
Considerations:\nPatient condition\nPatient’s Tx plan\nReason for Venous access\nAvailability of Catheter\nSkill of person placing catheter
Site selection – Patient Condition:
Do they have any trauma?\nAre they dyspnoeic?– they will need minimal restraint therefore cephalic may not be appropriate.
Site selection – Patient’s Tx Plan:
What is patient’s treatment plan?\nWill multiple types of fluids &/or medications be given?\nOr just IV fluids?\nHow long will catheter need to be in place?
Site Selection – Reason for Venous Access:
Reason for access will affect type of catheter and placement.\nMultiple blood sampling.\nDuring Sx in case of emergency.
Site Selection – Availability of Catheter:
You may not have required catheter on hand.\ne.g. Central lines are expensive & require expertise to place them.\nAlternative for high volumes of fluids – a large gauge over–the–needle catheter placed in jugular vein.
Site Selection – Skill of Person Placing Catheter:
Expertise of person placing catheter will affect which vein and catheter they choose.
Cephalic Vein
Most common vein used for IV catheter placement.\nEasily accessible & easy to see.\nCommonly placed in antebrachial part of cephalic vein. (between carpus & elbow, on cranio–medial aspect of limb)\nCephalic vein carries blood from the distal extremity to the jugular vein.
Cephalic Vein – Suitable Catheters:
Butterfly\nOver–the–Needle

Saphenous Vein – Lateral
Used as alternative to cephalic vein when they are not accessible (trauma etc), or if cephalic vein has been used and no longer viable.\nRuns along the lateral (outside) of the hind limb.\nNot as large as cephalic vein.\nCan be difficult to secure catheter in place.\nSaphenous vein carries blood to the femoral vein.
Saphenous Vein (Lat) – Suitable Catheters:
Butterfly\nOver–the–needle

Saphenous Vein – Medial
Runs along medial (inner) side of hind limb.\nGood vein for catheter placement but not often used.\nSecuring & maintaining catheter can be difficult.
Medial Saphenous Vein – Suitable Catheters:
