title: The Woggle technique for suture closure of hemodialysis access catheterization sites.
abstract: The Woggle technique is a modification of the purse-string suture technique, which is used to achieve hemostasis at hemodialysis catheterization sites. A tension collar (plastic guide wire introducer or similar device) is placed over the ends of a purse-string suture and secured with a suture lock (hemostat or stopcock) to tighten the suture without making a knot. The device is left in place for 20 to 60 minutes after the sheath is removed and then the woggle device is released and, if hemostasis is achieved, the suture is removed. This technique allows the patient to be discharged without a suture in place.
