Catheterisation

Question 1

Benefits of doing ultrasound guided central lines

Answer 1

Decreased procedure time
Real time needle visualisation
Decreased mechanical complications (pneumothorax, carotid artery catheterisation)
Decreased risk infections
Visualisation of surrounding structures
Cost effective
Increased first attempt success rate

Question 2

Advantages of out of plane technique for catheterisation

Answer 2

Easier for beginners
Avoid damage adjacent structures
Easier to hold probe
Better first pass success rate
Less complication rate

Question 3

Disadvantages of out of plane catheterisation technique

Answer 3

Difficult to track depth of needle
Can mistake shaft for tip of needle

Question 4

Advantages of “in plane” axis technique for catheterisation

Answer 4

Can track depth of needle

Question 5

Disadvantages of “in plane” catheterisation technique

Answer 5

Difficult to track needle
Unable to visualise structures on either side
Can’t change direction of needle
Dexterity needed, more advanced

Question 6

Advantages of ultrasound guided peripheral access

Answer 6

Increased first pass success
Decreased need for central access
Assists difficult cannulation
Obesity
