RESUMO

OBJECTIVE: World Health Organization recommends the use of maternal near miss as a tool to monitor and improve quality of obstetric care. Severe maternal outcome corresponds to the sum of maternal near miss and maternal death cases. This study was aimed at validating Acute Physiology and Chronic Health Evaluation II and IV, Simplified Acute Physiology Score III, and Sequential Organ Failure Assessment in pregnant and postpartum women in predicting severe maternal outcome. DESIGN: A retrospective cohort study. SETTING: Obstetric ICU in a tertiary care hospital in Brazil. PATIENTS: Pregnant and postpartum women admitted to the obstetric ICU during a 3-year period. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: A total of 279 women were admitted to ICU, an admission rate of 34.6/1,000 live births, and the mortality index to severe maternal outcome (maternal death/maternal near miss + maternal death) was 7.7%. Total Sequential Organ Failure Assessment had a better overall performance than remaining scores for total hospitalizations (area under the curve, 0.86; standardized mortality ratio, 0.96; 95% CI, 0.74-1.22), for hypertensive direct causes (area under the curve, 0.81; standardized mortality ratio, 0.73; 95% CI, 0.31-1.43), and indirect causes (area under the curve, 0.89; standardized mortality ratio, 0.85; 95% CI, 0.59-1.19). The Acute Physiology and Chronic Health Evaluation II had a better overall performance than total Sequential Organ Failure Assessment for hemorrhagic causes (area under the curve, 0.75; standardized mortality ratio, 1.0; 95% CI, 0.61-1.54). CONCLUSIONS: Total Sequential Organ Failure Assessment may be used to predict severe maternal outcome in obstetric populations admitted to ICU. The Acute Physiology and Chronic Health Evaluation II may be applied to predict severe maternal outcome in hemorrhagic complications. We do not recommend Acute Physiology and Chronic Health Evaluation IV and Simplified Acute Physiology Score III for the prediction of severe maternal outcome.

RESUMO

OBJECTIVE: To explore the epidemiological aspects, to describe the frequency and distribution of WHO maternal near miss (MNM) criteria and the presence of organ dysfunction and failure measured by the maximum SOFA (Sequential Organ Failure Assessment) score (SOFA max) in cases of severe maternal outcome (SMO). METHODS: In an observational cross-sectional study performed between January 2013 and December 2015, 279 pregnant or postpartum women were admitted to an obstetric ICU (intensive care unit) in Brazil. MNM, maternal death (grouped as SMO), and potentially life-threatening conditions (PLTC) were defined according to WHO criteria. For categorical variables, a descriptive analysis was carried out. Frequency and distribution of WHO criteria, organ dysfunction, or failure defined by SOFA max were performed. RESULTS: WHO criteria identified 65 SMO and 214 PLTC. Management criteria were present in 58/65 (89.2%) while 61/65 (93.8%) of SMO cases had dysfunction or failure by SOFA. CONCLUSIONS: The systematic evaluation of the organic function by SOFA max score identified the presence of organic dysfunction or failure in almost all SMO cases. Management criteria were present in all MD cases. Our results indicate the need for new studies evaluating the parameterization of the WHO laboratory criteria for values compatible with the definition of organic dysfunction by the SOFA to identify MNM.

RESUMO

INTRODUCTION: Cryptococcosis has become an important entity due to the epidemic of AIDS and therefore it is a significant opportunistic infection. However, there are case reports of cryptococcal meningitis in immune competent pregnant women. Since pregnancy is considered a period of relative immunosuppression, which likely prevents fetal rejection, this could explain the occurrence of opportunistic infections. OBJECTIVE: To report a case of cryptococcosis, and review all cases involving pregnancy and neurocryptococcal infection in immune competent pregnant patients. METHODS: Case report and systematic review of the literature using the MEDLINE and SciELO databases. DISCUSSION: A total of 27 patients were analyzed from 19 studies. The mean age at diagnosis was 26.4 years. There were six patients in their first trimester of pregnancy, 10 in the second, eight in the third and three post-partum. The most prevalent symptoms were headache (85.2%), altered vision (44.4%), altered mental status (44.4%), nausea (40.7%) and fever (33.3%). There were nine deaths (33.3%). Most of the patients received intravenous amphotericin B as treatment (77.8%). The majority (66.6%) of the patients accomplished a term delivery with healthy infants. CONCLUSION: Cryptococcal meningitis should be considered during pregnancy in cases of unexplained headache, altered vision, altered mental status, nausea and fever. Patients with a confirmed diagnosis should be admitted and treated with amphotericin B.

INTRODUÇÃO: Com a epidemia da AIDS, a neurocriptococose foi melhor estudada e considerada infecção fúngica oportunista. No entanto, há casos descritos de gestantes acometidas, apesar de imunocompetentes. A gestação, por si só, pode ser considerada um período de imunossupressão, para adaptação materno-fetal, o que poderia predispor à instalação de certas infecções. OBJETIVOS: Relato de caso de gestante com neurocriptococose e revisão sistemática dos casos descritos na literatura desta patologia durante a gestação, em pacientes imunocompetentes. METODOLOGIA: Revisão sistemática com busca MEDLINE e SciELO. RESULTADOS: Foram analisadas 27 pacientes com diagnóstico de neurocriptococse na gestação. A média de idade foi 26,4 anos. Seis pacientes estavam no primeiro trimestre de gravidez ao diagnóstico, 10 no segundo, oito no terceiro e três eram puérperas. O sintoma mais prevalente foi cefaléia (85,2 por cento), seguido por alteração visual (44,4 por cento), confusão mental (44,4 por cento), náusea (40,7 por cento) e febre (33 por cento). Houve nove óbitos maternos (33,3 por cento). Vinte e uma pacientes foram tratadas com anfotericina B (77,8 por cento). A maioria dos casos evoluiu com gestação a termo, com recém-nascidos saudáveis (66,6 por cento). CONCLUSÕES: Neurocriptococose deve ser um diagnóstico a se considerar na gestação, nos casos de cefaléia, alteração visual, confusão mental, náusea e febre persistentes, sendo indicada terapia intensiva e uso de anfotericina B.

RESUMO

Pulmonary embolism (PE) is a common condition. The central aim of this study was to describe the use of volumetric capnography (VCap) before and after fibrinolytic treatment of major PE. Lung scintigraphy was used as a base of comparison for the results of this treatment. We describe the cases of two conscious and spontaneously breathing patients (20- and by 24-year-old women) with major PE undergoing thrombolysis. Curves of CO(2) were obtained VCap and associated with arterial blood gas analysis and D-dimer. The pattern of VCap was compared with the VCap of health volunteers. Parameters also calculated were: P(a-et)CO(2) gradient, alveolar dead space fraction (AVDSf ), late dead space fraction (fDlate), and slope phase III (Slp III). The VCap results before and after thrombolysis for patients 1 and 2 were, respectively, P(a-et)CO(2): 12.6 to 5.8 and 7.9 to 1.6 (mmHg); AVDSf: 0.46 to 0.18 and 0.25 to 0.05; fDlate: 0.46 to 0.21 and 0.24 to 0.04; Slp III: 1.75 to 5.10 and 1.21 to 5.61 (mmHg/L). Lung scintigraphy was used to compare VCap results from the two subjects with VCap results from healthy volunteers and pigs before and after treatment associated with arterial blood gas, D-dimer, and showed satisfactory agreement.
