Venous Air Embolism

VAE development
open communication • between vein & atmosphere
pressure gradient enabling air entrainment• Vessel lumen : atmospheric pressure
volume and rate of air entrained• size of communication• pressure gradient
![Page 13: Central Line Audit Cycle Dr Coralie Carle B Med Sci BMBS FRCA, SpR 4 Anaesthesia & ICM Dr Ibrahim Ibrahim, MBChB ST 2 Anaesthesia Dr Simon Mills, MBChB.](https://reader036.fdocuments.in/reader036/viewer/2022062519/56649e4b5503460f94b3f97a/html5/thumbnails/13.jpg)
100mls can be fatal1
100mls: • 14G cannula• 1 second

Pressure gradient relative position of open communication
in relation to the RA• sitting position reduced CVP• resulted in the open communication of CVC
lying above RA
hydration status• Hypovolaemia decreases intravascular
pressure
mode of ventilation• Spontaneous inspiration decreases
intravascular pressure
CVP gasp reflex

Gasp reflex
VAE during spontaneous ventilation
10% obstruction to the pulmonary circulation can cause GASP REFLEX
reduces RA pressures and results in further air entrainment1

Outline R & D permission obtained
Phase 1• Assess current practice of CVC care in
relation to prevention of VAE in all locations throughout the hospital
• Presentation of results
Phase 2• Assess need for standard setting• Implement agreed standard
Phase 3• Audit at 1 & 6 months post intervention

• use of three-way taps?
hospital standard set
re-education• Poster

CVC insertion site:
CVC sutured to the skin at all times
Insertion site covered by an occlusive dressing
Removal:
Follow trust guidelines but remember to:
Lie the patient head down
Apply a sterile occlusive dressing
Prevent air from entering CVC:
Prime all syringes & IV giving sets
Use needle-free access devices if possible
Ensure bungs are not cross-threaded
Ensure correct 3-way-tap alignment:

• prevention
• management
our hospital’s approach
consider…
• need for CVC?
• lumens required?
• needle-free valves?
