Training with 3D Medsim game-based platform for intravenous cannulation before patient application

Practical training on a circulation model arm for intravenous cannulation before patient application

Participants in this group received practical training in peripheral intravenous cannulation (PIVC) using a game-based learning (GBL) simulation platform called 3D Medsim. The platform offered a scenario-based training environment that included a structured sequence of pre-test, simulated procedural performance, and post-test. Students were required to perform virtual tasks such as preparing the patient, selecting the correct equipment, identifying the puncture site, and performing cannulation. The simulation provided interactive feedback and scoring. The application was accessible via PC, tablet, or smartphone, allowing students to practice flexibly. Training was conducted under the supervision of an anesthesiologist.

The rate of successful intravenous cannulation performed by students on real patients under supervision. Success was defined as a successful puncture and catheter placement on the first or second attempt. Assessed by an anesthesiologist during clinical practice.

Students marked their perceived self-confidence regarding PIVC on a 10-cm visual analog scale (0 = no confidence, 10 = full confidence). Measurements were taken both after training and after clinical application.

Anxiety was measured using the State-Trait Anxiety Inventory - State Scale (STAI-S), a validated 20-item questionnaire assessing situational anxiety. Each item is rated on a 4-point Likert scale, yielding total scores ranging from 20 to 80, where higher scores indicate higher levels of anxiety (i.e., a worse psychological outcome).
