C-section incision opened up: what it means, what to do

How recovery typically progresses

Immediately after

First days

Most incision separation shows up early, typically 5 to 8 days after surgery while the wound is still in its earliest stage of recovery, though one case report describes superficial separation noticed as soon as the second day after delivery.

Settling in

Early weeks

As the days pass, watch for a change rather than assuming it's settled: new or heavier drainage, a bulge, or a pulling or popping feeling with coughing or straining are reasons to get it looked at rather than waiting for your scheduled postpartum visit.

Longer arc

Beyond six weeks

Once an opened area has been evaluated and cared for, most superficial separations close with straightforward wound care and resuturing rather than a return to the operating room; a deeper separation involving the abdominal wall layer beneath the skin is the exception that needs prompt surgical attention.

What does the evidence show for C-section incision opening?

• Wound dehiscence is a partial or total separation of previously approximated wound edges from a failure of the wound repairing itself properly, and this typically occurs 5 to 8 days after surgery, while recovery is still in its early stages. 1
• Recognized contributors to wound dehiscence include poor blood flow to the tissue, infection, increased pressure in the abdomen, diabetes, malnutrition, smoking, and obesity, along with increasing age, low blood protein levels, emergency surgery, and steroid use. 1
• Superficial dehiscence involves the wound edges separating along with increased bleeding or drainage at the site, while evisceration, where abdominal organs herniate through the open wound, is a complication of complete dehiscence and represents a surgical emergency managed by covering the area with a sterile saline dressing until it can be addressed. 1
• New or markedly increased wound drainage, or a new bulge in the abdominal wall, are indicators of dehiscence reaching the deeper fascial layer; a pulling or popping sensation during coughing, straining, or retching can be the first symptom, and 'salmon-colored' drainage is specifically concerning for this deeper involvement, with visible bowel needing to be wrapped in warm saline-moistened gauze and evaluated as an emergency. 2
• In one documented case, a roughly 4 cm superficial wound dehiscence was noted on the second day after a cesarean delivery, and management involved reapproximating the skin with sutures after removing the material that had failed. 3
• Reported rates of complete wound dehiscence after cesarean vary widely by setting, up to about 4% in high-income countries compared with as high as 30% in some studies from low- and middle-income countries, and in one tertiary-referral cohort of complete dehiscence cases, outcomes included blood transfusion in half of patients and a small number of maternal deaths, underscoring why a real separation needs prompt evaluation rather than home management alone. 4

When should I call my provider about C-section incision opening?

A new or markedly increased amount of wound drainage, a visible bulge at the incision, or a pulling or popping sensation during coughing, straining, or a bowel movement point toward the deeper fascial layer being involved and need prompt evaluation rather than a wait-and-see approach. Drainage described as salmon-colored, or any visible tissue at the wound, is a surgical emergency: cover it with a clean, saline-moistened cloth if available and seek emergency care immediately rather than driving yourself. Fever, spreading redness, or pus points more toward infection than mechanical separation, but either one, or a wound that is gapping open at all, deserves the same day of medical attention rather than the next scheduled visit. When in doubt, call your obstetric team the same day. Early input almost always beats waiting, and the on-call line exists exactly for this.
