    Topical antibiotics after suture repair?

    So, you’ve just finished suturing an uncomplicated laceration and you think to yourself: should I apply antibiotic ointment or just cover with a bandage with good return precautions?

     

    Answer: There is some limited evidence to support antibiotic ointment use.

     

    A study by Dire et al. in 1995 enrolled 465 patients with uncomplicated ED lacerations (including those that had absorbable subcutaneous sutures) to antibiotic ointment or petrolatum ointment with application 3times a day until patients returned for suture removal. The risk of infection of those treated with antibiotic ointment was 4.5-5.5% (depending on the type of antibiotic ointment) vs. 17.6% in those with petrolatum.  This gives you a NNT of ~8.
