Abstract
Objective

The authors analysed patients with severe partial respiratory failure (SPRF) admitted to a general Intensive Care Unit (ICU). The prevalence and clinical characteristics of these patients were evaluated.

This work aims to study the rate of and to clinically characterise the patient population admitted to an Intensive Care Unit with acute severe partial respiratory failure.

Material and methods

In 16-bed ICU of a central Hospital in Lisbon, patients admitted in the year 2004 were analysed. Patients with SPRF were recruited form patients with an ICU stay> 24 hours. They were selected according to PaO2 and FiO2 and clinically characterized.

Results

During the study period 472 patients were admitted, and 378 presented an ICU stay> 24 hours and were enrolled. From those, 142 (37.6%) met criteria for SPRF. Of these, 45 (31.7%) a pulmonary aetiology of SPRF was identified. Patients with SRPF were older, had longer ICU stay, and presented higher severity indexes and mortality. The prevalence of adult respiratory distress syndrome was possible to evaluate in the deceased patients with SPRF (n=52). In these we could find 12 (23%) patients that met criteria for that entity. By multivariate analysis the mortality of patients with SRPF correlated with older age and the presence of circulatory failure (p<0.001).

Conclusions

SPRF is a situation highly prevalent in the ICU studied. To better understand the prevalence of this entity, properly designed studies are needed in order to establish its epidemiology and clinical characteristics.

Resumo
Objectivos

A insuficiência respiratória parcial aguda (IRPA) grave é uma situação comum na prática dos cuidados intensivos, mas os estudos existentes são insuficientes. Com este trabalho pretendeu-se estudar a prevalência e caracterizar clinicamente a população de doentes internados numa UCI que apresentam insuficiência respiratória parcial aguda grave.

Material e métodos

Numa unidade de cuidados intensivos médico-cirúrgica avaliaram-se retrospectivamente os doentes internados durante o ano de 2004.

Resultados

37,6% dos doentes apresentaram IRPA grave. A análise estatística demonstrou que estes doentes diferiam dos doentes sem IRPA nos tempos de internamento e ventilação, índices de gravidade e mortalidade.

Conclusão

A IRPA é uma situação com elevada prevalência e relevância em cuidados intensivos, mas as características destes doentes estão mal definidas, em parte devido à ausência de critérios claros na sua definição.

Para melhor compreender este fenómeno são necessários mais estudos, prospectivos e multicêntricos.
