Medical Forum / General / General / October 2005Vasectomy and EMLA cream
Would it be a good idea to use a deseneitizer like EMLA cream on the skin prior to the lidocain shot given for vasectomy? It seems this would keep the shot from hurting badly. Has anyone had his before? I am scheduled for a vasectomy tomorrow and am a little scared. I have to take a 20 mg valium about 20 minutes before the procedure. > Would it be a good idea to use a deseneitizer like EMLA cream on the > skin prior to the lidocain shot given for vasectomy?

The pain from the local anesthetic comes from injecting the nerves around vas deferens - an intense-but-brief, dull pain that feels very much like getting smacked in the balls. Times two... EMLA won't help, it's not the skin injection that hurts. HMc Where exactly are the nerves at? I thought they injected directly into the vas? Is it that bad? So the pain you feel is actually in your testicles? > > Would it be a good idea to use a deseneitizer like EMLA cream on the > > skin prior to the lidocain shot given for vasectomy?

Times two... >> >> EMLA won't help, it's not the skin injection that hurts. The nerves run along with the vas deferens. The vas is easily palpable, so it's held between thumb and forefinger, a little skin wheal of local anesthetic is injected, then the needle advanced aiming for the vas, and the local anesthetic injected around it to block the nerves so that cauterizing/cutting/tying won't be painful. The nerves to the testicles (like the blood supply) originate further up in the retroperitoneum, so the pain felt from the testicles and the vas is mostly referred to the abdomen. The pain, like a testicular injury, is a dull, poorly localized pain felt somewhere in the abdomen. It's brief. HMc |
