Overview
This clinical trial aims to evaluate the safety and efficacy of an experimental tissue-engineered construct (TEC) based on amniotic membrane and calcium alginate for promoting epithelialization and improving scar quality in patients after cesarean section. The study will assess both biological and clinical indicators of wound healing, including cytokine dynamics (IL-6, IL-10), ultrasound characteristics, and patient-reported outcomes.
Description
The amniotic membrane (AM) is a natural biological material with regenerative and anti-inflammatory properties. In this study, a biodegradable tissue-engineered construct (TEC) combining amniotic membrane and calcium alginate is applied to the postoperative wound after cesarean section.
A total of 100 participants will be randomized into two groups:
- Experimental group - TEC application to the postoperative wound.
- Control group - standard postoperative wound care without TEC. Outcomes will include objective ultrasound measures of scar formation, cytokine profile changes, clinical scar evaluation (POSAS), and cosmetic appearance at 12 weeks.
Eligibility
Inclusion Criteria:
- Women aged 18 years and older.
- Planned elective cesarean section for medical indications (breech presentation, multiple pregnancy, large fetus, uterine scar, etc.).
- Absence of severe obstetric complications (e.g., preeclampsia, hemorrhage, placental abruption).
- No decompensated chronic diseases or acute infections.
- Signed written informed consent.
Exclusion Criteria:
- Acute infectious, autoimmune, or oncological diseases.
- Severe pregnancy complications (preeclampsia, eclampsia, decompensated gestational diabetes).
- Emergency cesarean section.
- Severe postpartum complications: massive bleeding (\>1000 mL), infection, abscess, severe anemia, allergic reactions to dressing materials.
- Withdrawal of consent or inability to continue participation.
