Changing perspectives of infectious causes of maternal mortality

Abstract

Objective: Infections significantly contribute to maternal mortality. There is a perceived change in the spectrum of such infections. This study aims to estimate the contribution of various types of infections to maternal mortality. Material and Methods:We retrospectively reviewed records of maternal death cases that took place between 2003 and 2012 in the Christian Medical College, Vellore, India. The International Classification of Diseases-Maternal Mortality was used to classify the causes of deaths and World Health Organization near-miss criteria were used to identify organ dysfunction that occurred before death. Infections during pregnancy were divided into three groups, i.e., pregnancy-related infections, pregnancy-unrelated infections, and nosocomial infections. Results:In this study, 32.53% of maternal deaths were because of some type of infection as the primary cause. The contribution of pregnancyrelated infections was comparable with that of pregnancy-unrelated infections (16.03% vs. 16.50%). Metritis with pelvic cellulitis, septic abortions, tuberculosis, malaria, scrub typhus, and H 1 N 1 influenza (influenza A virus subtype) were among the most commonly encountered causes of maternal death due to infections. Another 7.07% of cases developed severe systemic infection during the course of illness as nosocomial infection. A significant majority of mothers were below 30 years of age, were primiparae, had advanced gestational age, and had operative delivery. Cardiovascular and respiratory system dysfunctions were the most common organ dysfunctions encountered. Conclusion:The contribution of pregnancy-unrelated infections to maternal deaths is significant. Control of these diverse community-acquired infections holds the key to a reduction in maternal mortality along with the promotion of clean birthing practices. Nosocomial infections should not be underestimated as a contributor to maternal mortality.

Maternal mortality at a tertiary care teaching hospital in Dibrugarh district, Assam: a retrospective study

“…7,9 Halder et al reported the causes of maternal deaths that had signs of severe systemic infection. 18 It is seen that the causes found in the present study was directly or indirectly related to maternal mortality which coincides with many studies across India. Studies have found that haemorrhage, sepsis, eclampsia and obstructed labour account for 80% of all maternal deaths worldwide.…”

Maternal mortality and factors affecting it, among pregnant women in Abeokuta South, Nigeria

“…Majority of the pregnant women believed that infection can cause maternal death. This agrees with the indings of Halder, Vijayselvi & Jose [34]. Hypertensive disorders of pregnancy are one of the most common direct causes of maternal mortality [35][36][37][38][39].…”

Analisis Faktor Determinan Kematian Ibu di Kabupaten Sukoharjo Jawa Tengah Indonesia

“…Adanya komplikasi masa nifas terutama infeksi dapat menyebabkan kematian maternal akibat menyebarnya kuman ke dalam aliran darah (septikemia), perdarahan pada masa nifas dapat berlanjut pada terjadinya kematian maternal terutama bila ibu tidak segera mendapat perawatan awal untuk mengendalikan perdarahan. 7 Hasil analisis statistik menunjukkan pengaruh antara paritas dengan kematian maternal (OR = 0,035; 95% CI : 0,004 -0,300; p = 0,000). Hasil penelitian ini sesuai dengan Penelitian Kozuki et al bahwa paritas dan usia ibu telah terbukti dapat meningkatkan risiko prematuritas, dan kematian.…”
