ABSTRACT Post caesarean wound infection is not only a leading cause of prolonged hospital stay but a major cause of the widespread aversion to caesarean delivery in developing countries. In order to control and prevent post caesarean wound infection in our environment there is the need to access the relative contribution of each aetiologic factor. Though some studies in our environment have identified factors associated with post caesarean wound infection, none was specifically designed to address these issues prospectively or assess the relative contribution of each of the risk factors.
Prospective multicentre study over a period of 56 months in Lagos Nigeria. All consecutive and consenting women scheduled for caesarean section and meeting the inclusion criteria were enrolled into the study. Cases were all subjects with post caesarean wound infection. Those without wound infection served as controls. Data entry and analysis were performed using EPI-Info programme version 6 and SPSS for windows version 10.0.Eight hundred and seventeen women were enrolled into the study. Seventy six (9.3%) of these cases were complicated with wound infection. The proportion of subjects with body mass index greater than 25 was significantly higher among the subjects with wound infection (51.3%) than in the subjects without wound infection (33.9%) p = 0.011. There were also significantly higher proportions of subjects with prolonged rupture of membrane (p = 0.02), prolonged operation time (p = 0.001), anaemia (p = 0.031) and multiple vaginal examinations during labour (0.021) among the women that had wound infection compared to the women that did not have wound infection. After adjustment for confounders only prolonged rupture of membrane (OR = 4.45), prolonged operation time (OR = 2.87) and body max index > 25 (2.34) retained their association with post caesarean wound infection.
Effort should be geared towards the prevention of prolonged rupture of fetal membrane and the reduction of prolonged operation time by the use of potent antibiotics, early intervention and use of good surgical technique. In obese women improved surgical technique and use of non absorbable sutures may suffice.

    ABSTRACT: The aim of this study was to determine the incidence of surgical site infections (SSI) in patients undergoing a Caesarean section (CS) and to identify risk factors, common bacterial pathogens and antibiotic sensitivity. SSI significantly affect the patient's quality of life by increasing morbidity and extending hospital stays. A retrospective cross-sectional study was conducted in Nizwa Hospital, Oman, to determine the incidence of post-Caesarean (PCS) SSI from 2001 to 2012. This was followed by a case-control study of 211 PCS cases with SSI. Controls (220) were randomly selected cases, at the same hospital in the same time period, who had undergone CS without any SSI. Data was collected on CS type, risk factors, demographic profile, type of organism, drug sensitivity and date of infection. The total number of PCS wound infections was 211 (2.66%). There was a four-fold higher incidence of premature rupture of the membranes (37, 17.53%) and a three-fold higher incidence of diabetes (32, 15.16%) in the PCS cases compared with controls. The most common organisms responsible for SSI were Staphylococcus aureus (66, 31.27%) and the Gram-negative Escherichia coli group (40, 18.95%). The most sensitive antibiotics were aminoglycoside and cephalosporin. Polymicrobial infections were noted in 42 (19.90%), while 47 (22.27%) yielded no growth. A high incidence of associated risk factors like obesity, hypertension, anaemia and wound haematoma was noted. Measures are recommended to reduce the incidence of SSI, including the implementation of infection prevention practices and the administration of antibiotic prophylaxis with rigorous surgical techniques.

    ABSTRACT: During cesarean delivery, extracting a deeply impacted head is a real challenge for obstetricians. To compare selected maternal and fetal outcome indicators of the "pull" (reverse breech extraction) and "push" methods for impacted fetal head extraction during cesarean delivery. A computer-based search of the Medline, Cochrane library, and HINARI databases. Studies that compared the maternal and perinatal outcomes of the push and pull methods for impacted fetal head extraction during cesarean delivery were included. A meta-analysis of Mantel-Haenszel odds ratios and standardized mean differences from 11 randomized comparative and retrospective cohort studies was performed. In the pooled analysis, the risk of uterine incision extension was more than 8 times higher with the push method than with the pull method. Blood loss and operation time were also increased with the push method, and this method was associated with more perinatal deaths and admissions to the neonatal intensive care unit. The risk of wound infection was not significantly different between the 2 methods. The present meta-analysis demonstrated marked reductions in uterine incision extension, blood loss, and operation time with reverse breech extraction.
