RESUMO
BACKGROUND: Obstetric Morbidity Extreme (OME) is a promising addition to the investigation of maternal deaths and is used for the evaluation and improvement of maternal health services is defined as a severe obstetric complication that threatens the life of the pregnant woman and requires urgent medical intervention to prevent death of the mother. OBJECTIVE: To identify association between diseases and obstetric morbidity Extreme. MATERIAL AND METHOD: Transversal review analytical records. We searched for codes related to conditions that could cause extreme obstetric morbidity and the indirect causes that might cause it. RESULTS: The prevalence of OME 21 per 1000 newborns, diseases with greater association were eclampsia, liver failure and preeclampsia yielded the highest OR and statistical significance, the association of OME derived from surgery despite having a high prevalence in the analysis showed no association, in the same way if other variables showed association but had no significance and confidence intervals are below the unit that is the case of renal failure, metabolic failure and blood transfusion. CONCLUSIONS: The OME is caused by group entities specific disease (FLASOG) in most cases such as preeclampsia, eclampsia and obstetric hemorrhage.
