Brief Summary:
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

Detailed Description:
The investigators conducted this randomized controlled trial from April 2018 to July 2020 at the Department of Obstetrics and Gynecology at Menoufia University Hospital which is a large tertiary center in the Delta region in Egypt with a delivery rate of about 10000 per year This study was approved by Menoufia university hospital ethical committee Institutional review board 198190PSGN33 The investigators obtained informed consent from all participants before initiating any study procedures CONSORT guidelines were observed and completed
The patients included in the study were between 20 and 40 years of age Eligible women had one or more of the following risk factors Body mass index BMI 30 kglcm2 prior cesarean section pregestational or gestational diabetes hypertensive disorders of pregnancy placenta Previa twin pregnancy anemia and corticosteroid medication Exclusion criteria were chronic pain disorders hepatitis thrombocytopenia and coagulation disorders
The investigators randomized participants in a 11 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
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 For all patients the skin was closed with polyprolene 2-0 suture with a curved cutting needle The patients were examined by the physicians who were blinded to the group allocation on day 1 and then day 7 and 6 months after the procedure
Pain was evaluated by the visual analog scale system VAS which assesses changes of pain via a continuous measurement instrument that is operationally comprised of a horizontal line anchored at each end by verbal descriptors such as no pain and the worst pain imaginable The subject is asked to indicate a spot on the scale that best represents her degree of pain 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
The primary outcome was the Redness Edema Ecchymosis Discharge Approximation REEDA scale 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
The secondary outcomes were measured by Vancouver scar scale VSS and VAS VSS use to detect changes of formation of keloids or hypertrophic scars It assesses 4 subjective variables vascularity heightthickness pliability and pigmentation within a possible range of 0 - 14 for the total score
The sample size was calculated by using Epi-Info program version 354 by adjusting confidence interval to 95 With an alpha error of 5 and study power of 80 and assuming a clinically relevant reduction in REEDA and VSS scores based on results of previous studies the invesigators estimated a total sample size of 182 women 91 for each group This was increased to 200 women considering about 10 drop out rate The data collected were tabulated and analyzed by SPSS statistical package for the social science software statistical package version 20 Chicago Inc USA the following tests were used Quantitative data were expressed as mean and standard deviation X SD and analyzed by applying student t test Qualitative data were analyzed by Chi Square test P-value at 005 was used to determine significance regarded as non-significant P 005 significant P 005 or highly significant P 0001
