RESUMO
INTRODUCTION: Genital tract integrity is not always mantained during childbirth. No treatment protocol for post-partum perineal wounds (tears and episiotomies) existed in our Department, thus their management depends upon clinician. This study aimed to establish the role of antibiotic in the treatment of post-partum perineal wounds as well as the impact of antibioprophylaxis on wound healing and on prevention of infectious complications after repair. METHODS: We conducted a prospective cohort study in the Department of Gynecology and Obstetrics at the Central Hospital of Yaoundé over a period of 6 months, from 1 January to 31 May 2016. Post-partum women with perineal tear and/or episiotomy were divided into two groups (A and B) and followed up. The group A was composed by 85 post-partum women under treatment protocol based on compresses soaked in Betadine® (placebo). The Group B (or test group) was composed of post-partum women who had received placebo plus antibiotic (oral amoxicillin/clavulanic acid 875 mg/125 mg twice a day for 05 days). Both groups were followed up on day 0, day 2 and day 9. Our criteria for the evaluation of treatment were: pain, infection, swelling, cleanliness of the wounds and average healing time. Data were collected and analyzed using the software Epidata analysis version 3.2 and STATA version 12.0 (Texas USA 2001). The correlations between the variables were identified by chi-square, odds ratio and p value (using any p-value ≤ 0.05 as statistical significance cut-off) according to the case. RESULTS: The average age was 26.32 ± 6.5 years, ranging between 15 and 43 years. Primiparous women accouted for 55.9% of the study population. At day 0 post-partum the main symptom was pain, without significant predominance of a group (OR = 0.9; CI = 0.14-7.19; p = 1). Swollen wounds were the second complaint, without significant variation between the two groups (OR = 1.69; CI = 0.88-3.24; p = 0.13). At day 0, day 2 and day 9 no significant variation was observed between the two treatment protocols with regard to the indicators analyzed: pain evolution, infection, swelling and average healing time. At day 9 the healing was complete in both groups and the two treatment protocols were shown to be equivalent in their effectiveness and prevention of infections. CONCLUSION: At the end of this study the two treatment protocols were shown to be equivalent. Antibiotics should not be prescribed for perineal wounds in order to contain the healthcare costs.
