Bedside ultrasound to detect early post‑laparotomy wound fluid and predict infection

Post-Laparotomy Fluid Monitoring With Point of Care Ultrasonography : Predicting Surgical Site Infection & Optimizing Patient Convalescence (SPOTLIGHT Study).

NA · Slagelse Hospital · NCT07549880

This project will try bedside ultrasound on adults after open abdominal surgery to see if early fluid under the skin predicts a surgical site infection.

What this trial studies

This observational study will enroll adults who have had emergency or planned open abdominal surgery and perform a single wound swab and three bedside ultrasound scans of the surgical wound on postoperative days 1–3, 4–6, and 7–9. Wounds will be inspected for redness, swelling, tenderness, or discharge before each scan, and standardized wound photography and ASEPSIS scoring will be recorded. Participants will be followed at 7 and 30 days after surgery (and up to 90 days if an implant is present) to record surgical site infections. The study aims to link early subcutaneous fluid collections seen on point-of-care ultrasound with later development of SSI.

Who should consider this trial

Good fit: Adults over 18 undergoing emergency or elective open laparotomy with primary or delayed primary wound closure who can give informed consent and are treated at participating Danish hospitals are ideal candidates.

Not a fit: Patients who had laparoscopic procedures, wounds healing by secondary intention, those on ongoing negative pressure wound therapy, or non‑Danish residents are not eligible and would not benefit from this protocol.

Why it matters

Potential benefit: If successful, earlier detection of fluid collections could allow faster treatment and reduce the rate and severity of surgical site infections.

How similar studies have performed: Point‑of‑care ultrasound is established for identifying superficial fluid collections in other settings, but using serial bedside ultrasound specifically to predict post‑laparotomy SSI is relatively novel and not yet proven.
