Randomized Controlled TrialTopical anesthetic EMLA for postoperative wound pain in stereotactic gamma knife radiosurgery: a perspective, randomized, placebo-controlled study.
Patients who undergo stereotactic gamma knife radiosurgery (GKRS) need a rigid frame fixation for the stereotactic procedures. Many patients suffered from postoperative wound pain after frame removal. The present study investigated whether an additional application of a topical anesthetic prior to frame removal could reduce this discomfort. ⋯ EMLA when applied 60 min before frame removal has an anesthetic effect of reducing the postoperative wound pain in patients who undergo GKRS.
