[What's the optimal time of cesarean section antibiotic prophylaxis, before skin incision or after umbilical cord clamping? A prospective randomized study]. / Quel est le moment optimal de l'antibioprophylaxie pour césarienne élective, avant l'incision cutanée ou après clampage du cordon ombilical ? Étude prospective randomisée.

OBJECTIVES: To compare the effect of antibiotics prophylaxis within 30 mins before skin incision (A) and after umbilical cord clamping (C) on the incidence of postoperative infections in patients undergoing elective caesarean section at Farhat Hached university teaching hospital. MATERIALS AND METHODS: We conducted a randomised clinical trial evaluating 279 patients undergoing elective caesarean section. Patients were randomly assigned a group number that allocated them to either arm of the study. They received the same prophylactic antibiotic (cefazol® 2g) according to their allotment. They were followed up to detect infection up to 30 days postoperatively. The primary outcome was postoperative infection. The data collected were analysed with SPSS version 18.0 using univariate and bivariate analysis. RESULTS: The risk of overall postoperative infection was not significantly lower when prophylaxis was given before skin incision (4.37 % (A) vs 9.85 % (C); P=0.07; OR=0.42 [0.15-1.12]). We also found wound infections to be significantly reduced in the pre-incision group (2.2 % [A] vs 8.45 % [C]; P=0.03; OR=0.24 [0.06-0.88]). However, there was no difference in the endometritis infectious. On the other hand, there was no negative impact on the neonatal features. CONCLUSIONS: Giving prophylactic antibiotics before skin incision reduces risk of postoperative infection, in particular of wound infections.

[Post-cesarean parietal scar characteristics are predictive of pelvic adhesions. A prospective cohort study]. / Les caractéristiques de la cicatrice pariétale de césarienne sont des facteurs prédictifs des adhérences pelviennes. Étude de cohorte prospective.

OBJECTIVE: To investigate whether abdominal scar characteristics could predict the incidence and severity of intra-abdominal adhesions found at repeat cesarean delivery. PATIENTS AND METHODS: Prospective cohort study including 151pregnant women with at least one previous cesarean delivery and who delivered abdominally in the department of obstetrics and gynaecology of Farhat Hached teaching hospital-Sousse-Tunisia, during 6 months. Abdominal scar characteristics were studied. The main outcome measure(s) were the incidence and severity of intra-abdominal adhesions. Statistical analysis was performed using SPSS 18.0. RESULTS: Of 151 women enrolled into this trial, 111 (73.5%) had adhesions, 57 (37.8%) had dense adhesions. Of all the abdominal scar characteristics studied, a depressed scar was associated with an increased incidence of both dense and filmy intra-abdominal adhesions and frozen pelvis if compared of women who did not have a depressed scar (P<10(-4) ; RR=7.6; IC=2.98-19.45). A number of previous cesarean section equal or more than 2 was also correlated with an increased incidence of severe intra-abdominal adhesions and frozen pelvis if compared with women who had only one previous cesarean section (P=0.002; RR=2.53; IC=1.16-5.56). DISCUSSION AND CONCLUSION: A depressed abdominal scar of a previous cesarean delivery and a number of previous cesarean sections are significantly correlated with the incidence and severity of intra-abdominal adhesions.
