Stitches (sutures) hold tissues together after injury or surgery, closing the wound to promote healing. The body initiates an inflammatory response following closure. This response involves increased blood flow and fluid production at the site, which prevents infection and begins tissue regeneration.
Expected Appearance and Minor Spotting
A small amount of fluid discharge from a sutured wound is common during the initial phase of healing. This discharge is typically a thin, pink or light red fluid known as serosanguineous drainage, representing a mixture of clear plasma fluid and red blood cells. This normal byproduct of the body’s early inflammatory response is generally expected within the first 48 to 72 hours post-procedure.
The volume should be minimal, appearing as light spotting or splotches on a dressing, rather than soaking it completely. Dried, dark red blood may sometimes be visible around the knots of the stitches. This minor seepage is not a cause for concern and usually resolves as the incision line seals and the initial inflammatory period subsides.
Identifying Excessive or Concerning Bleeding
While minor seepage is normal, certain signs indicate that the bleeding is excessive and requires immediate medical evaluation. The most objective measure is volume; bleeding that quickly soaks entirely through the surgical dressing is concerning. If the blood is bright red, indicating fresh bleeding, and continues to flow, it suggests an active hemorrhage that needs professional attention. Bleeding is also concerning if it persists and does not stop after applying gentle, consistent pressure for 15 minutes.
Beyond visible blood loss, systemic symptoms include feeling faint, dizzy, or experiencing a rapid increase in heart rate. Bleeding accompanied by a sudden, severe increase in pain or rapid swelling at the incision site should also prompt an immediate call to the healthcare provider. The presence of purulent drainage—thick, white, yellow, or brown fluid—along with warmth, increasing redness, or a foul odor, suggests a possible wound infection.
Managing the Wound Area
For minor, expected spotting, several steps can manage the wound area and support healing. If minor seepage occurs, apply clean, gentle, and consistent pressure directly over the wound using a sterile gauze or clean cloth. Maintaining this pressure for up to 15 minutes without interruption can allow a clot to form and stop the flow. If the dressing becomes saturated, change it to a fresh, sterile one to keep the wound environment clean.
When cleaning the area, only use mild soap and water or sterile saline solution, gently washing around the suture line. Avoid using irritating substances like hydrogen peroxide or alcohol, which can damage new tissue and delay the healing process. If the wound is on a limb, elevating the area above the level of the heart can help slow the blood flow and assist in controlling minor, persistent oozing.
