Objective: to identify the perception of obstetric nurses about the healthcare model and practice in a philanthropic maternity hospital. Method: qualitative study of 13 obstetric nurses working in a Minas Gerais maternity hospital. Researchers used semi-structured interviews for data collection which took place from September 2015 to February 2016. Data analysis used content analysis. Results: the following categories emerged: Performance based on humanization and good practices; Professional autonomy; Professional mentoring during decision making; Teamwork and Performance Model. Discussion: research revealed that nurses are autonomous and work as a team; they did not single out a healthcare model and identified work demand and technocratic model as obstacles. Final considerations: management support is important for the professionals’ performance since it contributes to autonomy at work. Despite the progress made, there are still challenges both in terms of staff and communication, as well as management support.

JUSTIFICATIVA E OBJETIVOS: O Strongyloides stercoralis é um agente comum de infecção do trato gastrintestinal. Em pacientes imunodeprimidos este nematódeo pode causar hiper-infecção, com manifestações pulmonares e sepse por germes gram-negativos. O objetivo deste relato foi apresentar um caso com evolução letal e ressaltar a importância do diagnóstico e do tratamento precoce. RELATO DO CASO: Paciente do sexo masculino, 60 anos, com diagnóstico de tumor de timo, submetido a tratamento cirúrgico, radioterapia e quimioterapia. Foi consultado na emergência relatando queixa de diarréia e dispnéia, sendo admitido na UTI após apresentar quadro de insuficiência respiratória aguda hipoxêmica e choque refratário, evoluindo para óbito. No aspirado traqueal, foi identificado larvas de Strongyloides stercoralis. CONCLUSÕES: A estrongiloidíase, apesar de tratar-se de infecção parasitária freqüentemente leve, em pacientes imunodeprimidos pode apresentar-se de forma grave e disseminada. Deve-se suspeitar deste agente em pacientes que vivem em áreas endêmicas, sendo o diagnóstico estabelecido através da pesquisa da larva do Strongyloides stercoralis na secreção traqueal e nas fezes.BACKGROUND AND OBJECTIVES: Strongyloides Stercoralis is a common cause of gastrointestinal infection. This nematode can produce an overwhelming hyperinfection syndrome, especially in the immunocompromised patient. Typically, patients present with pulmonary symptoms, but subsequently they can acquire Gram-negative sepsis. The objective of this report is to describe a lethal case and call attention to the importance of early diagnosis and treatment. CASE REPORT: Male patient, 60 year-old with diagnosis of timoma, treated with surgery, radiotherapy and chemotherapy in the past. He presented to the emergency room complaining of diarrhea and dyspnea, and then transferred to the ICU after development of hypoxemic acute respiratory failure and refractory septic shock, and despite treatment the patient died. A bronchial sample of sputum showed Strongyloides stercoralis worms. CONCLUSIONS: Strongyloides stercoralis infection symptoms are usually mild, but in the setting of impaired host immunity, a disseminated and severe illness may occur. Clinicians must be aware for patients from endemic areas. Diagnosis may be established through sputum and stool examination for Strongyloides stercoralis worms.
