Figure 6

In vivo dislodgement and fluoroscopic evaluation—Following fluoroscopic drain placement, the impacts of pull forces on internal drain placement were compared between our novel securement component (SC), with a break away mechanism, and a drain stitch, the current standard of care. Fluoroscopy demonstrates proper drain positioning (a) with our novel SC attached and no pull force applied (green circle). A pull force is applied (blue circle) with maintenance of the drain pigtail position (b). The pull force was increased until the SC break away mechanism reached its detachment threshold (red circle) throughout which time the drain pigtail remains in an identical location (c). In contrast, a drain was placed under fluoroscopy and secured using a drain stitch (d). A pull force was applied with partial internal migration of the drain tip (e). The pull force was increased until failure of the drain stitch resulting in complete dislodgement of the drain (f). Figure was produced using Microsoft PowerPoint V16.72.
