Follow the guidelines as outlined in the general anesthesia handout.


Site Care

Keep the wound clean and dry for 24 hours. You may get them wet. Your doctor may use Dermabond (a sterile liquid glue used to close the incision). It’s OK to get the Dermabond wet. Allow the Dermabond to peel off on its own.



Apply ice pack wrapped in a towel over dressing to decrease pain and swelling—on 20 minutes, off 20 minutes as needed. Take acetaminophen for pain as directed.



As tolerated. You may shower after 24 hours with the bandage on. If there’s an Ace wrap (elastic bandage) in place, remove it after 24 hours.



You should be able to urinate within 6-8 hours. if you’re unable to do so, contact Telehealth Nursing at 651-229-3890.
