Comparing the effectiveness of oral versus intravenous antibiotics in the prophylaxis of wound infection in hand laceration

Hand lacerations are among the most frequent causes of visiting emergencydepartments (EDs). Wound infection is one of its complications. There is still an ongoingdisagreement on the administration of oral versus intravenous (IV) antibiotics (ABs). Theobjective of this study is to compare the effectiveness of oral versus IV ABs in preventingwound infection of hand lacerations. In this double-blind, randomized clinical trial, we enrolled all patients with handlacerations (based on the inclusion criteria) during 6 months in the EDs of 2 tertiary referralcenters. Convenient sampling was done. Finally, in the first group, 382 patients receivedoral AB (two 500 mg cephalexin capsules) and the other 382 patients in the second groupreceived IV AB (1 gr IV cefazolin) before wound management. Both groups were followedand received oral cephalexin during 48 hours after suturing. Rates of wound infection anddifferent complications were compared between the two groups. T-test, Mann-Whitney Utest, Chi square and Fisher analysis were used. Both groups had the same age and gender distribution rate (79.8% of males withthe mean age of 30.8 years in the first group, and 83.5% of males with the mean age of 32.6years in the second group (P = 0.19 and 0.39, respectively). In our study, wound infectiondeveloped in 2.6% and 1.8% of patients in the first and second groups, respectively (P =0.46). Based on the results of this study, oral and IV ABs were not significantlydifferent in terms of preventing wound infection
