Presentation
Ergonomic Surgical Intervention Table for Transcatheter Aortic Valve Replacement procedures
DescriptionBackground
Procedures in the catheterization laboratory often have fixed patient beds and tables behind the surgeons that complicate workflow and cause spatial constraints. This leads to repetitive awkward turning and leaning motions in surgeons that can lead Work-Related Musculoskeletal Disorders (WMSDs) in the back and neck. This work evaluates the effect of a surgical intervention table placed above the patient and in front of operators on postural risks. The Transcatheter Aortic Valve Replacement (TAVR) procedure was chosen as a benchmark because of its complex workflow, standardization between surgeons, and low-risk nature.
Methods
To evaluate ergonomics, 9 consultants (8 male) and 3 fellows (2 male) performing TAVRs at the Mayo Clinic were recruited. Each surgeon performed procedures using both the baseline workflow, and the intervention workflow. To evaluate postural risks of the neck, torso, and arms, data was collected using Inertial Measurement Units.
Results
A total of 120 surgeon-cases were collected (66 baseline, 53 intervention). Amongst consultants, use of the intervention table yielded significant reductions in percent surgical duration in risk 3 (higher risk postures) coupled with increase in percent surgical duration in risk 1 (low risk postures) for the neck and the torso. However, in intervention cases, consultants also spent greater percent surgical duration in risk 2 and 3 (moderate and high-risk postures) coupled with a decrease in surgical duration in risk 1 (low risk postures) for both arms. This suggests that while this intervention table may help the neck and torso, the trade-off is increased risk to the arms.
