This document discusses arterial cannulation. It outlines the objectives of understanding the indications, insertion methods, and care of arterial lines. Arterial lines are indicated for continuous blood pressure monitoring and frequent blood sampling. They are typically inserted using the Seldinger technique, and care involves checking the site regularly for bleeding or infection and using minimal dressings.

ARTERIAL CANNULATION

2. OBJECTIVES
By the end of this lecture students will be able to know
the :
 Indications of arterial cannulation.
 Methods of insertion of arterial cannulation.
 Care of arterial line.

3. INDICATION
a) Continuous beat-to-beat monitoring of blood
pressure.
b) Frequent blood sampling for lab analysis.

4. METHODS OF INSERTING ARTERIAL
CANNULATION
 The Seldinger technique
 Performed by accessing the artery with a needle
 Feeding a guidewire through the needle lumen.
 Placing catheter in the artery by feeding it over the
guidewire.
 Removing the guidewire leaving only catheter.

6. CARE OF ARTERIAL LINE
 Check the site 6 hourly to assess for bleeding.
 Use minimal dressing material.
 Assess for evidence of compromised color,
circulation or motion.
 Lines should be removed if there are signs of
infection

7. SUMMARY
 Arterial lines are placed to monitor beat to beat
blood pressure in critical patient.
 The technique of insertion is usually seldinger
technique.
 Care of arterial line is by vigilant observation of the
site and cleaning.
