Objective: To assess the effect of autologous Platelet Rich Plasma (PRP) on wound healing and pain perception in high risk women undergoing cesarean sections in a low resource setting.
Methods: This was a randomized controlled trial of 200 women who attended the outpatient clinic of Menoufia University Hospital for elective cesarean surgery. The women were randomly assigned to two groups. The intervention group received PRP after surgery, whereas the control group received the usual care. Outcomes included Redness, Edema, Ecchymosis, Discharge, Approximation (REEDA) scale, Vancouver scar scale (VSS), and the visual analog scale (VAS).
|Condition or disease||Intervention/treatment||Phase|
|Infection||Drug: Platelet rich plasma||Phase 4|
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||200 participants|
|Intervention Model:||Parallel Assignment|
|Masking:||Double (Participant, Outcomes Assessor)|
|Masking Description:||The invesigators randomized participants in a 1:1 ratio to two equal groups containing one hundred patients each (intervention and control groups). A statistician not directly involved in the study prepared a computer generated randomization list and placed the allocation information in sequentially numbered sealed envelopes that were opened according to the attendance of the patients after signing the informed consent. The study authors were unaware of the envelope allocation sequence. Participants and outcome assessors did not know which group had been assigned to for the duration of the study.|

Active Comparator: Platelet Rich Plasma
In the operating room before the start of each procedure, approximately 15 cm of whole blood was drawn from the uninvolved arm of each patient in the intervention group (group I) into a 20 ml sterile syringe containing citrate for anticoagulation. The blood was immediately centrifuged at 3200 Revolutions per Minute (PRM). Following 15 minutes of centrifugation, 4 - 5 mL of PRP was obtained. Then, the PRP was buffered by using sodium bicarbonate. After closure of the fascia and prior to skin closure, PRP was directly applied to the subcutaneous tissue of the wound site by using a sterile syringe.

In the control group (group II), the patients did not receive topical treatment and the subcutaneous tissue was cleaned with normal saline before skin closure
- Redness, Edema, Ecchymosis, Discharge, Approximation scale changes [ Time Frame: day 1, day 7 and 6 months ]for assessing the changes in wound healing. REEDA as a descriptive scale has 4 points in a categorical score that measures 5 items of healing: redness (hyperemia), edema, ecchymosis, discharge, and approximation of the wound edges (coaptation). Each item is rated on a scale of 0 to 3, and total scores may range from 0 to 15. A lower score indicates better healing
- Vancouver scar scale changes. [ Time Frame: day 1, day7, and 6 months ]Vancouver scar scale (VSS) use to detect changes of formation of keloids or hypertrophic scars. It assesses 4 subjective variables: vascularity, height/thickness, pliability, and pigmentation within a possible range of 0 - 14 for the total score. A lower score indicates better healing.
- Visual Analog Scale changes [ Time Frame: day 1, day7, and 6 months ]Pain was evaluated by the visual analog scale system (VAS) which assesses changes of pain via a continuous measurement instrument.The score is determined by measuring the distance (mm) between the no pain anchor to the point that the patient marks, providing a range of scores from 0 - 10. A higher score indicates greater pain intensity
