A- line technique

Q: While inserting arterial line which approach has the better chance of first stick success?

A) Direct puncture

B) Use of a guidewire


Answer:  B

Studies have shown that the guidewire approach either separate-guidewire or integral-guidewire has a better chance of success on the first stick than a direct puncture. 


Also, direct puncture takes longer to perform, and more attempts with the use of more catheters.
