For all patients, full history will be taken followed by complete physical examination, obstetric ultrasound & routine preoperative investigations. GA is established by menstrual dates then confirmed by obstetric ultrasound. Spinal anaesthesia will be given for all patients. All cesarean sections will be done by ob/gyn residents under the supervision of senior staff obstetrician using the following technique: Pfannenstiel skin incision, transverse lower uterine segment incision, two-layer closure of the uterine wall, closure of both parietal peritoneum & rectus sheath & skin closure (using prolene 3/0 suture). Primary maternal outcome includes postoperative endometritis (diagnosed if maternal axillary temperature ≥ 38°C for at least 48 hours, uterine tenderness, infected lochia & leukocytosis).Secondary maternal outcomes include wound infection (diagnosed if there is induration, redness, hematoma, seroma or purulent discharge at the incision site) & urinary tract infection (diagnosed if there frequency, dysuria, suprapubic or loin pain & positive urine culture). Prolonged postoperative hospital stay (more than 2 days) will also be recorded. The infectious morbidity evaluation will be done by ob/gyn residents who will be blinded to the study group of the patient. Neonatal outcomes include immediate antibiotic adverse effects (diarrhea & rash), neonatal sepsis (diagnosed by clinical signs, leukocytosis, C-reactive protein& positive blood culture), neonatal intensive care unit (NICU) admission (entailing the length of stay) & neonatal death. All neonates will be examined by an expert neonatologist who will be blinded to study group of the neonate's mother. On discharging all patients, a brief summary about symptoms and signs of the above mentioned infectious & neonatal complications will be given and they will be instructed to contact any of the authors immediately if any happens. Patients will be reexamined after 1 week (skin stitch removal appointment) & 4 weeks (contraception counseling appointment) following the CS.
