Q

Jugular Vein

A

Travels along ventral aspect of neck in the muscular jugular groove, from mandible to shoulder.\nMuch larger vein than cephalic & saphenous.\nOften used for blood sampling & placing catheters in small patients. \nJugular vein drains blood from the head.

17
Q

Jugular Vein – Suitable Catheters:

A

Butterfly\nOver–the–Needle\nThrough–the–Needle (for central lines)

A

The marginal ear vein is used.\nCommonly used in small ‘pocket’ pets.\nSometimes used in dogs such as Bassett Hounds.\nUsed for blood sampling & IV catheter placement.

20
Q

Ear Vein – Suitable Catheters:

A

Often used in small pets (pocket pets / rodents).\nUsed for blood sampling.\nSize of patient determines if a catheter can be placed or not.\nSpecific IV catheters are available for rodents.\nTail vein used for blood collection in large animals (e.g. Cattle).
