episiotomy repair avoid tightly tied sutures tissue ischemia guideline
Tightly tied episiotomy sutures can cause pressure on the small blood vessels in the vaginal/perineal tissues. This reduces local blood flow, causing:
- Ischemia - tissue receives too little oxygen and nutrients.
- Venous obstruction and swelling - blood can enter more easily than it drains, so edema increases tissue pressure further.
- Tissue strangulation - the suture acts like a constricting band.
- If prolonged or severe, cell death (necrosis) can occur. The wound may then become painful, dusky/black, break down, or become infected.
Sutures should bring wound edges together without blanching, puckering, or strangulating them. A continuous, non-locking, absorbable technique is commonly used to reduce tension and pain. The episiotomy repair goal is anatomical alignment and hemostasis with minimal suture material, as described in Roberts and Hedges’ Clinical Procedures in Emergency Medicine, Episiotomy Repair.
Seek urgent obstetric assessment if there is increasing severe perineal pain, worsening swelling, foul discharge, fever, wound opening, or dark/black tissue. These can indicate infection, hematoma, impaired blood supply, or wound breakdown.

Feracrylum drug class topical hemostatic agent ferric acrylic polymer
Feracrylum is a topical local hemostatic agent or styptic.
- It is an iron salt of polyacrylic acid.
- Used locally to control capillary/surface bleeding, for example after dental extraction or during certain surgical procedures.
- It promotes clot formation locally and forms a protective protein film over the bleeding surface.
- It is not a systemic anticoagulant or antifibrinolytic drug.
It may also have local antimicrobial and hygroscopic properties. A clinical study description identifies 1% feracrylum as an aqueous iron-polyacrylic acid solution with local hemostatic action.
