| Abstract | BACKGROUND: Local anesthesia used for incision and drainage of abscesses is known to be painful. STUDY OBJECTIVE: We studied the analgesia provided by a lidocaine/tetracaine patch compared to injectable lidocaine during incision and drainage (I&D) of skin abscesses. METHODS: This was a prospective, double-blind, randomized, controlled trial carried out in the Emergency Department (ED) of an adult tertiary referral center. Adult patients with a skin abscess in need of I&D were randomized to one of two groups. One group received a lidocaine/tetracaine patch and injectable normal saline for anesthesia. The second group received a placebo patch and injectable 1% lidocaine. A visual analog pain scale was used to record the patient's pain level prior to treatment, during the procedure, and after I&D. RESULTS: There were 20 patients enrolled in the study, including 12 randomized to the lidocaine/tetracaine patch and 8 to the injectable lidocaine. Pain scores preprocedure were similar in the two groups. Pain scores during I&D and postprocedure were compared between groups using a paired t-test. Patients receiving injectable lidocaine experienced pain that was similar (50.1 ± 5.9 mm; 95% confidence interval [CI] 45.2-55.1) to those receiving the transdermal lidocaine/tetracaine patch (60.1 mm ± 11.0; 95% CI = 55.2-68.1), p = 0.04, with a power of 80% to detect a difference of 20 mm at p ≤ 0.05; although this was statistically significant, it was not clinically significant. There was also no statistical difference between the two groups in the postprocedure pain scores (p = 0.65). CONCLUSION: Local injection of lidocaine provided clinically similar analgesia compared to the lidocaine/tetracaine patch during I&D of skin abscesses in the ED. Pain at presentation and after the procedure was similar in both groups. Emergency physicians should continue to use a local injected anesthetic for I&D of skin abscesses until a less painful alternative is identified. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
