Using an in dwelling arterial line is the method of choice for frequent blood analysis in adult critical care areas. 0.9% (normal͛) sodium chloride solution is the recommended flush solution for maintaining the patency of arterial catheters. The unintentional use of a glucose-containing solution for flushing results in artefactually high glucose concentration has led to insulin administration causing hypoglycaemia and fatal brain injury.
This guideline makes recommendations on:
- Arterial pressure monitoring and sampling systems and techniques
- The prescription checking and administration of arterial line infusions
- Glucose monitoring and insulin administration
