Seventy-two patients undergoing interventional procedures were randomized to 3 groups for anesthetic administration just prior to sheath removal. Group 1 (control) received no local anesthetic. Group 2 (local) received 10 ml of lignocaine directly infiltrated with syringe and needle around the sheath. Group 3 (Friend) had the Friend inserted with the sheath and 10 ml of lignocaine was delivered via the device. Pain around the sheath was assessed prior to, during and just after, sheath removal using a 5 point verbal scale. ⋯ The Friend device is a new, inexpensive and safe method of reducing pain associated with removal of arterial sheaths after cardiac interventional procedures.
