ObjectiveTo 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.Study DesignAn open-label, randomised clinical trial.Place And Duration Of Study(UHS) Izmir Bozyaka Training and Research Hospital, Izmir, Turkey, from 1st to 30th July 2019.MethodologyAnalysis 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.ResultsComparison 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.ConclusionThe 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.Key WordsCentral venous catheter, Medical training, Simulation-based training, Ultrasonography.
