AbstractThe incision and drainage of a sacrococcygeal abscess is a common procedure in the Emergency Department (ED) both to decrease a patient's pain and to improve the local wound conditions for subsequent definitive surgical therapy. However, the local infiltration of anesthetics is often problematic due to the unacceptable and unavoidable pain resulting from the injection itself, as well as the inability to achieve a complete anesthetic response. Therefore, standard textbooks generally recommend the concomitant use of local and systemic analgesics in the treatment of sacrococcygeal abscesses. We describe herein an alternative technique to administer local analgesia after the aspiration of an abscess for incision and drainage of a sacrococcygeal abscess that is safe and rapid. The patient is placed in the prone position and the buttocks are separated from the midline with adhesive tape. The technique involves needle aspiration of the abscess with consecutive slow injections of the same amount of local anesthetic into the abscess cavity via the same needle, followed by abscess drainage by incision and gentle curettage. This method therefore eliminates multiple infiltrations of the abscess and the surrounding area and obviates the associated pain due to the low volume of anesthetic required. The described technique is well tolerated by the patient and reduces the frequently encountered difficulty with incision and drainage of coccygeal abscesses in the ED.
