| Sumario: | Post-surgical infections in patients who underwent cesarean sections (PIPC) are responsible for significant postpartum morbidity and increase in hospital costs.
This study intended to investigate the incidence of PIPC, the prevalence of microorganisms involved and epidemiological factors such as age, hypertension, obesity, previous pregnancy controls (PC), type of C-section and antibiotic prophylaxis (AtbP).
Retrospective study of patients who underwent C-sections from 01/01/2014 to 12/31/2017 in a Maternity Hospital of Cordoba city. Fifty infected patients and a non-infected control group (n: 22) were analyzed. We used Pearson's chi-squared test for categorical variables; multivariate analysis of conglomerates (MVAC) in addition to multiple correspondence analysis (MCA) were also performed. Results: In the studied period, we performed 5941 C-sections, 80 of which developed infections (1.34%). Fifty-three samples of 50 patients underwent bacteriological analysis: 46 abscesses of the abdominal wall, 5 samples of peritoneal fluid, 1 endometrial aspirate and 1 blood culture. Patient's age ranged between 16 and 48 years, median: 25 years (95%, CI 22-27). Twenty-seven out of 53 (51%) cultures developed aerobic germs and 19/53 (36%) anaerobic microorganisms. From the total of samples received, 23/53 (43%) yielded 46 strains of Gram-positive cocci (GPC): Staphylococcus aureus (SAU): 17/46 (37%), Coagulase negative Staphylococci: 13/46 (28%), Enterococcus faecalis and viridans group streptococci: 8/46 (17%) strains of each one. Twelve of the 53 samples (23%) developed 16 strains of Gram-negative bacilli (GNB): Proteus mirabilis: 6/16, Escherichia coli: 5/16 and 1/16 strain of a different enterobacteriaceae. The analysis of PICP regarding AtbP was significant (p=0.03) whereas it was irrelevant for the other categorical variables. However, the MAC grouped AtbP, PC and non-infected patients within the same conglomerate. This finding was also observed with the MCA (discriminative variable loads in the same dimension) as well as in the perceptual map.
Aerobic germs prevailed over anaerobic ones and GPC over GNB, being SAU the most frequently detected microorganism. MVAC allowed us to detect possible relevant variables for PICP, such as lack of AtbP and PC. |
