Breech presentation at a district level hospital in South Africa

Introduction: The Term Breech Trial has led to obstetricians opting for Caesarean section as the mode of delivery for this presentation, even in poor countries. Concerns related to this approach are the resultant increase in Caesarean section rates and their associated complications, particularly in under-resourced countries, which are faced with financial and human-resource expertise constraints.Method: This was a retrospective chart review of women who presented at term with a singleton breech presentation at the antenatal clinic and in labour, from January 2005 to December 2007, at a district level hospital in South Africa.Results: There was a total of 19 197 deliveries, of which 466 were singleton term breech deliveries, giving a rate of 2.4%. Of the 297 women who had antenatal care and had been allocated to planned Caesarean section, 271 had the planned operation. There were no neonatal deaths in the planned Caesarean section group. The emergency Caesarean section group and the group in which no decision was made on the mode of delivery were associated with higher maternal complication rates than in the group that had planned Caesarean sections. The highest neonatal complication rate was in the group that had unplanned vaginal deliveries.Conclusion: In a district hospital in South Africa, the mode of delivery for breech presentations is usually a planned Caesarean section. Unplannedvaginal deliveries are associated with significant perinatal mortality.Keywords: breech deliveries; district hospital; poor countrie

Second-stage primary Caesarean deliveries: Are maternal complications increased?

Background: Second-stage Caesarean sections (CSs) are known to be associated with increased complications but most reports originate fromtertiary hospitals, which attend to high-risk patients. Complication rates may differ in district hospitals, which attend to low-risk patients.Methods: This was a retrospective study carried out at a district maternity unit in Durban. The hospital records of all CSs over an eight-month periodwere reviewed and obstetric and neonatal complications of second-stage CSs were compared with a group of first-stage CSs performed during thestudy period.Results: There were 4 654 deliveries, including 1 257 CSs, in the study period. The CS rate was 27.2%. Of 617 (8.5%) emergency CSs, 53 wereperformed in the second stage of labour.The maternal and neonatal complication rates were low and no statistical differences were found between the patients who had second-stage orthose who had first-stage CSs, except for increased blood loss, blood-stained urine, prolonged operative times and postoperative fever for secondstageCSs.Conclusions: Second-stage CSs performed in a district hospital are associated with increased maternal complication rates but not with neonatalcomplications

A randomised controlled trial of suture materials used for caesarean section skin closure: Do wound infection rates differ?

Objective. The aim of this study was to determine wound complication rates following the use of suture materials and staples for skin closure at caesarean section (CS). Study design: A randomised, controlled, prospective study was undertaken.Results. A total of 1 100 women was assigned randomly into 3 groups: polyglycolic acid (PGA) suture group (N=361), skin staple (SS) group (N=373) and nylon suture group (N=366). The overall wound infection rate was 7%. There was no difference in respect of number of patients, age, parity and gestation between the study groups. Those who had nylon sutures as opposed to PGA sutures were 9.5 times more likely to experience wound infection (p=0.055). Women who had SS were at 6.93 times higher risk of wound infection than those who had PGA sutures (p=0.014). Other factors influencing wound infection rates included: rupture of membranes >12 hours were 13.7 times (95% confidence interval (CI) 3.9 - 47.9, p <0.0001) more likely to have wound infection than those with rupture of membranes <12 hours. For every 1-minute increase of surgery duration, the risk of infection increased 1.094 times (95% CI 1.046 - 1.145; p <0.0001). HIV-infected women were 53.4% less likely to develop wound infection than their uninfected counterparts (odds ratio 0.466, 95% CI 0.238 - 0.913; p =0.026). As the time period of observation increased from baseline to day 3 and from day 3 to day 10, wound infection risk increased by 35 times (95% CI 8.155 - 150.868; p <0.001).Conclusion. The use of SS for CS wound closure is associated with a significantly greater risk of wound infections. SS for wound closure at CS is not recommended for use in South African district hospitals.S Afr Med J 2012;102(6):374-376

Critical pathways for the management of preeclampsia and severe preeclampsia in institutionalised health care settings

BACKGROUND: Preeclampsia is a complex disease in which several providers should interact continuously and in a coordinated manner to provide proper health care. However, standardizing criteria to treat patients with preeclampsia is problematical and severe flaws have been observed in the management of the disease. This paper describes a set of critical pathways (CPs) designed to provide uniform criteria for clinical decision-making at different levels of care of pregnant patients with preeclampsia or severe preeclampsia. METHODS: Clinicians and researchers from different countries participated in the construction of the CPs. The CPs were developed using the following steps: a) Definition of the conceptual framework; b) Identification of potential users: primary care physicians and maternal and child health nurses in ambulatory settings; ob/gyn and intensive care physicians in secondary and tertiary care levels. c) Structural development. RESULTS: The CPs address the following care processes: 1. Screening for preeclampsia, risk assessment and classification according to the level of risk. 2. Management of preeclampsia at primary care clinics. 3. Evaluation and management of preeclampsia at secondary and tertiary care hospitals: 4. Criteria for clinical decision-making between conservative management and expedited delivery of patients with severe preeclampsia. CONCLUSION: Since preeclampsia continues to be one of the primary causes of maternal deaths and morbidity worldwide, the expected impact of these CPs is the contribution to improving health care quality in both developed and developing countries. The CPs are designed to be applied in a complex health care system, where different physicians and health providers at different levels of care should interact continuously and in a coordinated manner to provide care to all preeclamptic women. Although the CPs were developed using evidence-based criteria, they could require careful evaluation and remodelling according to each system's demands. Additionally, the CPs need to be tested in large-scale, multi-level studies in order to thoroughly examine and evaluate their efficacy and effectiveness

Hair Trace Element and Electrolyte Content in Women with Natural and In Vitro Fertilization-Induced Pregnancy

The objective of the present study was to perform comparative analysis of hair trace element content in women with natural and in vitro fertilization (IVF)-induced pregnancy. Hair trace element content in 33 women with IVF-induced pregnancy and 99 age- and body mass index-matched control pregnant women (natural pregnancy) was assessed using inductively coupled plasma mass spectrometry. The results demonstrated that IVF-pregnant women are characterized by significantly lower hair levels of Cu, Fe, Si, Zn, Ca, Mg, and Ba at p < 0.05 or lower. Comparison of the individual levels with the national reference values demonstrated higher incidence of Fe and Cu deficiency in IVF-pregnant women in comparison to that of the controls. IVF pregnancy was also associated with higher hair As levels (p < 0.05). Multiple regression analysis revealed a significant interrelation between IVF pregnancy and hair Cu, Fe, Si, and As content. Hair Cu levels were also influenced by vitamin/mineral supplementation and the number of pregnancies, whereas hair Zn content was dependent on prepregnancy anthropometric parameters. In turn, planning of pregnancy had a significant impact on Mg levels in scalp hair. Generally, the obtained data demonstrate an elevated risk of copper, iron, zinc, calcium, and magnesium deficiency and arsenic overload in women with IVF-induced pregnancy. The obtained data indicate the necessity of regular monitoring of micronutrient status in IVF-pregnant women in order to prevent potential deleterious effects of altered mineral homeostasis
