Use Antibiotics at 2nd Degree OB Lac Repair?

Do you routinely order prophylactic antibiotics at time of second-degree laceration repair? Is there data for that? While the use of prophylactic antibiotics “is reasonable” (per ACOG PB 198) for OASIS lacerations, what does the data look like for second degree lacs? Well, the answer is both supportive AND non-supportive of that practice! In this episode, we will cover a brand new publication (RCT) from BMJ on this very issue, and also highlight a meta-analysis from Plos One (May 2025) that also examined this question.
