Abstract:
This prospective crossover study compared the incidence of posterior vessel wall
puncture between two approaches during ultrasound-guided simulated central
venous cannulation by anaesthesiology trainees. Each phantom model, simulating
a central vein and artery, was cannulated by 37 anaesthesiology trainees under
ultrasound-guidance using the in-plane approach (IPA) and out-of-plane approach
(OPA). Total procedural time and the time taken from starting image scanning until
commencing puncture, was recorded. The number of attempts required to achieve
successful venous cannulation was noted. Finally, the models were examined for
posterior venous wall and arterial puncture. Total procedural time was shorter
with the OPA (26.5 vs 50.3 seconds, p=0.001). The time taken from starting image
scanning until commencing puncture was shorter for the OPA (2.2 vs 12.3 seconds,
p<0.0001). The IPA resulted in significantly more attempts for cannulation. Twenty
and eleven participants were successful within the first pass using the OPA and
IPA, respectively (p=0.034). There was no difference in the incidence of posterior
vessel wall puncture between these two techniques. The OPA resulted in less
arterial puncture compared to the IPA (2 vs 9, p=0.022). The incidence of posterior
vessel wall puncture between the IPA and OPA during ultrasound-guided simulated
central venous cannulation by anaesthesiology trainees was comparable.
