1. A catheter assembly, comprising:
a catheter adapter comprising a proximal end, a distal end, and a longitudinal axis extending between the proximal end and the distal end;
a catheter extending from the distal end of the catheter adapter;
a dressing to apply traction to the catheter in response to the catheter being disposed within a vasculature of a patient, the dressing comprising a first section adjustably coupled to a second section, wherein the first section is configured to secure at least one of the catheter adapter and the catheter to the patient, wherein the first section includes an aperture configured to surround an insertion site of the catheter, and wherein the second section is distal to the first section and positionable on a side of the aperture opposite the proximal end of the catheter adapter, the second section configured to be adjustably secured relative to the first section along the longitudinal axis of the catheter adapter to apply the traction to the catheter within the vasculature; and
an adjustment element to adjustably couple the first section to the second section, wherein the adjustment element comprises a plurality of tethers coupled to and extending between the first section and the second section, and wherein each of the plurality of tethers is configured to be adjusted individually to apply the traction on the catheter.
 
9. A catheter assembly, comprising:
a catheter adapter comprising a proximal end, a distal end, and a longitudinal axis extending between the proximal end and the distal end;
a catheter extending from the distal end of the catheter adapter;
a dressing to apply traction to the catheter in response to the catheter being disposed within a vasculature of a patient, the dressing comprising a first section adjustably coupled to a second section, wherein the first section is configured to secure at least one of the catheter adapter and the catheter to the patient, wherein the first section includes an aperture configured to surround an insertion site of the catheter, and wherein the second section is distal to the first section and positionable on a side of the aperture opposite the proximal end of the catheter adapter, the second section configured to be adjustably secured relative to the first section along the longitudinal axis of the catheter adapter to apply the traction to the catheter within the vasculature; and
an adjustment element to adjustably couple the first section to the second section, wherein the adjustment element comprises a plurality of tethers coupled to and extending between the first section and the second section, and wherein the plurality of tethers is configured to be adjusted collectively to apply the traction on the catheter.
