          Abstract

          Neste estudo a monitorização de 35 pacientes de terapia intensiva, submetidos a ventilação mecânica, permitiu estabelecer o nível de precisão de dois oxímetros de pulso de diferentes fabricantes. O desempenho foi determinado em função de dados comparativos obtidos pela hemo-oximetria, para proceder a análise estatística foi utilizado o teste t. Pacientes críticos são portadores de condições clínicas que podem, eventualmente, limitar o uso desta técnica. No presente trabalho foi demonstrado que a discrepância nos resultados obtidos pode ser atribuída a presença de metemoglobina e possivelmente à anemia associada a hipóxia.

          Translated abstract

          In this clinical investigation 35 patients under mechanical ventilation were studied. It was possible to establish the precision of two pulse oximeters of different brands. The performance of these equipments was evaluated by comparing data with the hemo-oximeter and a statistical analysis employed the student t test. Results showed that bias between oximeters reading and hemo-oximeter was similar for both instruments. Eventually critical patients may present conditions that limit the use of this technique. The study showed that the discrepancy in the results observed may be attributed to the presence of the methemoglobin and possible to anaemia associated to hipoxia.

          Nitrobenzene poisoning and spurious pulse oximetry.

          The successful management of nitrobenzene poisoning in a 21-year-old patient is presented. We report our experience of ventilatory care with additional intravenous methylene blue and ascorbic acid therapy. Pulse oximeters available at present are not useful in patients treated with methylene blue and should be used cautiously in the presence of cyanosis of unknown aetiology.
