Key Learning Points
1. Ultrasound guidance is the gold standard of care for central line insertion.
2. The number of unsuccessful attempts at cannulation is directly proportional to the likelihood of subsequent complications.
3. Factors such as current clinical condition, body habitus, co-morbidities and intended duration of catheterisation should influence the choice of puncture site.
4. The length of guidewire and catheter used is determined by the side and site of insertion.
5. The puncture site should be regularly assessed for signs of infection – line-associated sepsis is a significant cause of morbidity in the critical care setting.
