RESUMO
Background: Urinary tract catheterization is a major risk factor for urinary tract infections (UTIs). Catheter associated urinary tract infections (CAUTIs) still remain a major reservoir of antibiotic resistant pathogens with attendant increase in morbidity and mortality. Objective: To determine and compare the incidence of catheter associated urinary tract infections following immediate and 24-hour postoperative removal of urethral catheters for caesarean section. Design: The study was a prospective, comparative study. Place and Duration of Study: Labour ward, Theatre and Postnatal wards of Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi between August 2012 to April 2013. Methodology: The study involved 156 women admitted for caesarean section where the urethral catheters were removed 24-hour post operatively (group A) or immediately after caesarean section (group B). Urine samples were collected. Outcome measures included pre-operative and 72 hour postoperative urine microscopy, culture and sensitivity, urinary frequency, dysuria, urgency, fever and duration of hospital stay. The patients’ data were coded, computed and analyzed using SPSS version 16. A P-value of <0.05 was considered significant. Results: Of the 79 patients in group A, 9 (11.4%) had significant bacteriuria in the 72 hour post operative urine culture while 5 (6.5%) had significant bacteriuria in group B, (OR=1.85: 95% CI 0.59-5.80, P=0.28). The overall incidence of catheter associated urinary tract infection in NAUTH was 14(9.0%). Escherichia coli were mostly isolated 4 (44.4%). The lowest level of resistance was seen with Amoxycillin- clavulanic acid (Augmentin). Conclusion: The present study showed that significant bacteriuria in Group A almost double the incidence in Group B, however, the difference was not statistically significant. Further studies should be carried out to compare catheterization with non- catheterization for caesarean section.
RESUMO
Background: Despite numerous studies, the exact aetiology of pre-eclampsia remains unknown. Some studies have shown that supplementation of calcium and magnesium could ameliorate the effects of pre-eclampsia. The objective of this study was to compare the calcium and magnesium levels in the serum of Nigerian women with or without pre-eclampsia. Methods: In this study, serum calcium and magnesium levels were determined using atomic absorption spectrometry in 54 patients and 48 healthy normotensive pregnant women. The mean, standard deviation, Student’s‘t’ test and Pearson correlation were employed. Results: Serum calcium was significantly lower in patients than controls (9.17 ± 0.6 vs. 7.22 ± 0.5 mg/dl. P <0.001) (t test). Plasma Magnesium was significantly lower in patients than controls 13.19 ± 1.1 vs. 9.81 ± 0.7 mg/dl. P <0.001). The systolic and diastolic blood pressure showed significant inverse correlation with both calcium and magnesium (P<0.01). Conclusion: There was significant reduction in the levels of calcium and magnesium in patients with pre-eclampsia. Dietary supplementation of these trace elements may help to prevent pre-eclampsia.
