The Effect of a Local Injection of a Platelet Concentrate on Infection and Healing of Surgical Wounds
- Conditions
- Wound Infection and Wound Healing
- Registration Number
- NCT02869204
- Lead Sponsor
- Jens Rikardt Andersen
- Brief Summary
The purpose of this project is to investigate whether a combination of a local injection of platelet rich plasma (PRP) combined with a daily supplement of vitamin C, zinc, L-arginine, as well as high protein diet (1.5 g of protein per kilo body weight per day) can promote tissue healing in patients undergoing open upper-abdominal surgery.
Primary endpoint is cases of wound infection and secondary endpoints are time of tissue regeneration (days), judged by traditional clinical observation and experimentally assessed by ultrasound.
The experiment is performed as a parallel two-armed, randomized, controlled trial.
A total of 40 subjects will be included in the trial i order to ensure the power of the study, despite a drop off of up to 25%.

- Primary Outcome Measures
Name Time Method Number of patients with wound infection assessed by traditional clinical observation of the cicatrice From date of surgery until the date of first documented event of infection or date of death from any cause, whichever came first, assessed up to 30 days . Infection are defined as a collection of pus in the wound that require revision.
It is assessed by observation from the hospital staff.
- Secondary Outcome Measures
Name Time Method Length of stay (LOS) 30 days Number of days before the surgical wound are full epithelized assessed by observation of the cicatrice Up to 30 days Digital photos of the cicatrice will be collected and analyzed for the amount of remaining scab.
Other postoperative complications Up to 30 days Experience of pain assessed by a VAS (Visual analogue scale) Up to 30 days Mobilization assessed by "Timed Up & Go (TUG)" Up to 30 days Timed Up \& Go, also known as TUG, measures the time it takes a study subject to stand up, walk 3 meters, turn around, walk back and sit down.
Inflammatory responds assessed by blood sample analysis of the acute phase reactant CRP (c-reactive protein) Up to 30 days Inflammatory responds assessed by blood sample analysis of the acute phase reactant leucucytes Up to 30 days
