Abstract

OBJECTIVE: To determine whether a combination of topical anesthetic (EMLA) and local injection with lidocaine is better than lidocaine alone for pain relief after Ferguson hemorrhoidectomy. METHODS: Sixty patients scheduled for hemorrhoidectomy were randomized into 2 groups: (1) control group (CG, n=30) received neomycin ointment (5 g), and (2) EMLA group (EG, n=30) received EMLA (5 g), both agents applied topically after surgery. Before the surgical incision was made, lidocaine (10 mL of a 1% solution) was locally injected into all 60 patients. After surgery, analgesics were provided when necessary. The visual analog scale score was recorded at 4 time points: (1) upon arrival in the postanesthesia room, (2) 2 hours after arriving in the postanesthesia room, (3) between 9 and 10 PM on the first postoperative evening, and (4) on the first postoperative morning. The frequency of meperidine requests, 1-time catheterizations for urinary retention, and patient satisfaction with postoperative pain management, were also recorded. RESULTS: The median visual analog scale scores and cumulative dosages of meperidine were significantly lower in the EG than the CG (P<0.05). Patient satisfaction with postoperative pain control was also significantly higher in the EG than the CG (P<0.01). No systemic complications occurred. DISCUSSION: EMLA is considered a breakthrough in cutaneous analgesia, capable of reducing pain in many cutaneous procedures. Because Ferguson hemorrhoidectomy has been performed for years with ongoing concerns over postoperative pain, we felt that using EMLA could lower postoperative pain intensity and the number of requests for additional medication.
