Split-skin grafting with lidocaine-prilocaine cream: A meta-analysis of efficacy and safety in geriatric versus nongeriatric patients.
Although the efficacy and safety of the topical anesthetic EMLA cream (lidocaine-prilocaine) have been studied extensively in children and adults, no published studies have focused on geriatric patients (>/=65 years of age). The objective of this study was to compare the efficacy and safety of EMLA in geriatric versus nongeriatric adults. A pooled analysis was made from original data of six studies of EMLA cream for split-skin grafting. The studies selected had a sufficient number of geriatric and nongeriatric adults and a uniform, standardized pain stimulus (split-skin grafting), pain rating (visual analogue scale, verbal rating scale) and adverse event recording. A total of 182 geriatric patients (82 aged 65 to 74 years; 100 aged 75 to 96 years) and 221 nongeriatric EMLA-treated patients were evaluated. There was no difference in the efficacy of EMLA between geriatric and nongeriatric adults who underwent similar onset and duration of anesthesia. EMLA cream 1.5 g/10 cm2 applied for 2 to 5 hours had a similar anesthetic effect in both age groups. A dose of 3 g/10 cm2 gave no further benefit. In a geriatric population, EMLA cream provided effective cutaneous anesthesia for the cutting of split-skin grafts to the same extent as did infiltrated lidocaine. Adverse event frequency and severity were similar in geriatric and nongeriatric patients. Transient application site pallor, redness, and edema were the most frequent adverse events. Topical anesthesia with EMLA cream for split-skin grafting is as safe and effective in geriatric as in nongeriatric adults.
