Catheter securement dressings that aid in applying skin adhesive to a catheter insertion site are described. Catheter securement dressings can include a first dressing layer that secures a position of a catheter at a catheter insertion site following catheterization. The first dressing layer can include an access window that provides access to the catheter insertion site to allow for application of skin adhesive to the catheter insertion site. After the skin adhesive has dried, a second dressing layer can be folded over the first dressing layer to cover the access window.
