What it is
Local anesthetic is used to numb the perineal skin and tissue before suturing tears or episiotomy. It works within a few minutes and lasts long enough for repair. Can also be used to numb before performing an episiotomy if regional anesthesia isn't in place.

Current evidence
Standard of care per ACOG and obstetric anesthesia guidelines; well-established safety profile.
Where the evidence is clear · where people may choose differently
For most topics, guidelines from ACOG, WHO, and other major bodies broadly agree on the core safety points (when to act in an emergency, informed-consent standards, monitoring baselines). Where reasonable people — and even guidelines — differ tends to be around thresholds (when to start or stop something), preferences (comfort, environment, support), and values (how you weigh small risks against benefits). Use the questions below to explore those pieces with your care team.

Related evidence topics
- Perineal Tears (Grades 1–4)Most vaginal births involve some tearing. Grades 1–2 are common and heal well; grades 3–4 involve the anal sphincter and need specific repair and follow-up.
- EpisiotomyA cut made in the perineum during birth to enlarge the vaginal opening. Once routine, now only recommended for specific situations.
- Pudendal BlockLocal anesthetic injected near the pudendal nerve deep in the pelvis to numb the perineum and vagina for pushing, delivery, or repair.
- Epidural AnesthesiaRegional anesthesia delivered through a small catheter in the lower back to numb pain from the waist down during labor.
Questions to ask your care team
- ?Will lidocaine or a longer-acting agent be used?
- ?If I have an epidural, can we top it up instead?
Universal questions (works for any decision)
A short BRAIN-style set you can bring to any conversation about interventions, monitoring, or care decisions.
- ?Why are you recommending this now — is it urgent, routine, or optional?
- ?What happens if we wait an hour (or longer) before deciding?
- ?What signs would tell us this is working — or that we need to change course?
- ?What are the alternatives, including doing nothing?
- ?What would you recommend if this were your family?
- ?What would change your recommendation?
