Acutely sick patients can receive emergency intravenous access through central venous cannulation to administer fluids and medicines, perform haemodynamic monitoring and extracorporeal therapies, including plasmapheresis or haemodialysis. Using the Seldinger procedure, access is gained by percutaneous puncture, frequently guided by ultrasonography into the femoral, subclavian or internal jugular veins. This study aimed to identify ergonomic risk factors for musculoskeletal disorders (MSDs) in operators performing ultrasonography-guided internal jugular vein (IJV) cannulation at various table heights and probe orientations. Sixty emergency medicine residents participated in a cross-sectional study conducted by the Emergency and Trauma Department of Hospital Universiti Sains Malaysia, Kelantan. Participants were instructed to perform the cannulation at two distinct table heights and with two distinct probe orientations. To compute the ergonomic risk score, the Rapid Entire Body Assessment (REBA) method was used. The table height of 0.5 elbow factor with varied probe resulted in a median REBA score of 5.0, whereas the table height of 0.7 elbow factor with varied probe had a median REBA score of 4.0. All four positions exhibited medium risk for MSDs. This study showed that the table height of 0.7 elbow factor is more ergonomically favourable while still imposed medium risk for MSDs.
