Effectiveness of Using a Gelatine-Based Model in Ultrasonography-guided Jugular Central venous Catheter Placement Training: A Randomised Clinical Trial

To evaluate the effectiveness of using a gelatine-based model, that can be prepared easily and at a low cost, compared to training without a model in ultrasonography (USG) guided internal jugular venous catheter placement training. An open-label, randomised clinical trial. (UHS) Izmir Bozyaka Training and Research Hospital, Izmir, Turkey, from 1st to 30th July 2019. Analysis was conducted with the data of 48 participants (resident physicians-RP). Group 1 (n: 26) received imaging training with USG on a human subject and then performed needle insertion training on the gelatine-based jugular vein model with the USG guidance. Group 2 (n: 22) received the same imaging training with USG but did not perform needle insertion training. Evaluation of the participants included successful long axis vein imaging time, successful in-plane needle imaging, number of changes in needle angles, the total number of punctures, successful vein puncture time, successful catheterization time, and catheterization success with the gelatine-based test manikin. Comparison of the rates of successful in-plane needle imaging (Group 1: 92.3%, Group 2: 59.1%; p = 0.006), catheterization success (Group 1: 92.3%, Group 2: 59.1%; p = 0.006), successful catheterisation time (Group 1: 77.5 sec, Group 2: 152.5 sec; p = 0.026), and total complications (Group 1: 3.8%, Group 2: 31.8%; p = 0.010) demonstrated that the model-trained RPs were significantly more successful. The study results suggest that the use of a gelatine-based model in USG-guided central jugular vein catheterisation training can be an effective method to reduce complications.
