Study ObjectiveFingertip injuries are common in the pediatric population. Considerable controversy exists as to whether prophylactic antibiotics are necessary after repair of these injuries. Our goal was to compare the rate of bacterial infections among subgroups treated with and without prophylactic antibiotics. The study hypothesis was that infection rates were similar in the 2 groups.MethodsThis was a prospective randomized control trial of pediatric patients presenting to an urban children's hospital with trauma to the distal fingertip, requiring repair. Patients were randomized to 2 groups: group 1 received no antibiotics, and group 2 received antibiotics (cephalexin). Repairs were performed in a standardized fashion, and all patients were reevaluated in the same emergency department in 48 hours and again by phone 7 days after repair. The primary outcome measure was the rate of infection at 7 days after repair.ResultsOne hundred forty-six patients were initially enrolled in the study, 11 patients were withdrawn before study completion, 69 subjects were randomized to the no-antibiotic group, and 66 subjects were randomized to the antibiotic group. There was 1 infection in each group at 7 days after repair. The infection rate was 1.45% (95% confidence interval, 0.04%-7.81%) for the no-antibiotic group and was 1.52% (95% confidence interval, 0.04%-8.16%) for the antibiotic group, not statistically significant (P = 1.00).ConclusionsThis study suggests that routine prophylactic antibiotics do not reduce the rate of infection after repair of distal fingertip injuries.
