Introduction: The use of ultrasound in central venous access is the current standard due to its advantages in terms of efficiency and safety. In-plane or out-of-plane visualization are the techniques currently used without evidence showing an advantage of one over the other. The aim of this study is to compare biplane visualization with the in-plane and out-of-plane technique in terms of success and time in simulated models. Methodology: A simulated experiment was conducted in which 10 emergency medicine specialists participated in 60 simulated events, using a randomization visualization technique. For each referral event a simulated model for jugular venous access. The times required were measured to obtain an optimal window, to visualize the needle inside the vessel and for the adequate passage of the guidewire. Results: 100% success was obtained in channeling with the 3 techniques. Success on the first attempt was 95% for biplane viewing versus 100% for in-plane and out-of-plane viewing. There were no significant differences in cannulation success, needle redirection, or posterior wall puncture frequency of BP compared with EP and FP. Conclusions: Biplane visualization with the use of pocket ultrasound for internal jugular cannulation in simulated models did not show significant differences when compared with in-plane and out-of-plane visualization techniques.
