In Brazil, where 90% of the childbirths occur in hospitals, 67.1% of the cases of maternal death are due to direct obstetric causes, mainly hypertensive disorders, but a quarter of the deaths are due to indirect obstetric causes. As maternal death is a rare event, estimated in 76/100,000, the study of severe maternal morbidity, following international literature, can contribute to qualify obstetrical care. Maternal morbidity is a continuum that ends with death, but there is a separate group, with extreme severity, known as near miss. From the literature review, there are the difficulties to obtain an operational definition of the cases of extremely severe morbidity or near miss. The prevalence ranged from 0.80-8.23%, according to the defining criteria and health care provided at the region. The characterization of severe maternal morbidity and near miss allows for monitoring the process of obstetrical care and could help to qualify treatment of maternal urgencies and emergencies, interrupting the process that can lead to death.

Sentinel lymph node biopsy in the treatment of breast cancer has been replacing lymph node resection in early cases. This treatment may be performed with blue dye and/or radiopharmaceuticals. There are reports of allergic reactions to blue dye with different degrees of severity. A case of severe anaphylactic reaction after intradermal injection of patent blue dye was reported in a patient diagnosed with ductal carcinoma in situ. The patent blue dye facilitates the detection of the sentinel lymph node, but there is the risk of triggering anaphylactic reactions. It is recommended the team involved to be very knowledgeable and prepared to diganose and treat this complication.

PURPOSE: to apply a severity score to cases of severe maternal morbidity (SMM) and to compare the classification criteria. METHODS: a control-case study was performed as a secondary analysis of cases of SMM in a tertiary level maternity unit for a period of 12-month. A specific score for assessing the degree of severity was applied to cases identified as SMM. Twenty cases of near miss maternal morbidity (higher severity) were compared to 104 control cases (lower severity) of other severe morbidities, regarding risk factors, primary determinants and assistance requirements. Analyses were performed with means and proportions, using Student's t, Wilcoxon and chi2 statistical tests, and estimations of OR and 95% CI. RESULTS: the higher severity (near miss) was identified in 16.1% of cases and the history of abortion was the only factor statistically associated with it (OR=3.41, 95% CI 1.08-10.79). In fact, the indices of assistance complexity were more frequent in the near-miss morbidity group, which also presented less hypertension (30% against 62.5%) and more hemorrhage (35.5% against 10.6%) as primary determinant factors of severe morbidity. CONCLUSIONS: the higher severity of maternal morbidity was associated with a history of abortion and with hemorrhage as a cause. The applied score was able to identify a higher severity subgroup (near miss), which needs more complex professional and institutional care in order to avoid the occurrence of death.
