RÉSUMÉ
BACKGROUND AND OBJECTIVES: Worldwide, trauma is one of the leading causes of morbidity and mortality. The aim of the present study is to identify the predictors of mortality of trauma patients requiring Intensive Care Unit (ICU) admission. METHODS: This retrospective study was conducted in the ICU of our institution in Greece during a six-year period (2010-215). RESULTS: Among 326 patients, trauma was caused by road traffic accidents in .5%, followed by falls (21.1%) and violence (7.4%). Thirty-day mortality was 27.3%. Multivariate analysis showed that higher New Injury Severity Score (NISS), severe head/neck injury, acute kidney injury, septic shock and hemorrhagic shock were significantly associated with mortality while higher Revised Injury Severity Classification, version II (RISC II) and the administration of enteral nutrition were associated with survival. NISS showed the higher accuracy in predicting 30-day mortality followed by RISC II, while scores based only in physiological variables had lower predictive ability. CONCLUSIONS: Increased mortality was strongly associated with the severity of the injury upon admission. Traumatic brain injury, septic shock and acute kidney injury have also been found among the strongest predictors of mortality. NISS can be considered as a statistically superior score in predicting mortality of severely injured patients.

BACKGROUND AND OBJECTIVES: Subarachnoid haemorrhage is an important cause of morbidity and mortality. The aim of the study was to determine predictors of mortality among patients with subarachnoid hemorrhage hospitalized in an Intensive Care Unit. METHODS: This is a retrospective study of patients with subarachnoid hemorrhage admitted to the Intensive Care Unit of our institution during a 7 year period (2009-2015). Data were collected from the Intensive Care Unit computerized database and the patients' chart reviews. RESULTS: We included in the study 107 patients with subarachnoid haemorrhage. A ruptured aneurysm was the cause of subarachnoid haemorrhage in 76 (71%) patients. The overall mortality was 40% (43 patients), and was significantly associated with septic shock, midline shift on CT scan, inter-hospital transfer, aspiration pneumonia and hypernatraemia during the first 72 hours of Intensive Care Unit stay. Multivariate analysis of patients with subarachnoid hemorrhage following an aneurysm rupture revealed that mortality was significantly associated with septic shock and hypernatremia during the first 72 hours of Intensive Care Unit stay, while early treatment of aneurysm (clipping or endovascular coiling) within the first 72 hours was identified as a predictor of a good prognosis. CONCLUSIONS: Transferred patients with subarachnoid haemorrhage had lower survival rates. Septic shock and hypernatraemia were important complications among critically ill patients with subarachnoid haemorrhage and were associated increased mortality.

Resumo Justificativa e objetivos: A hemorragia subaracnoidea é uma causa importante de morbidade e mortalidade. O objetivo do estudo foi determinar os preditivos de mortalidade entre os pacientes com hemorragia subaracnoidea internados em uma Unidade de Terapia Intensiva. Métodos: Estudo retrospectivo de pacientes com hemorragia subaracnoidea internados na Unidade de Terapia Intensiva de nossa instituição de 2009 a 2015. Os dados foram coletados do banco de dados eletrônico da Unidade de Terapia Intensiva e de revisões dos prontuários dos pacientes. Resultados: Incluímos no estudo 107 pacientes com hemorragia subaracnoidea. A ruptura de aneurisma foi a causa da hemorragia subaracnoidea em 76 pacientes (71%). A mortalidade geral foi de 40% (43 pacientes) e esteve significativamente associada ao choque séptico, desvio da linha média na tomografia computadorizada, transferência inter-hospitalar, pneumonia por aspiração e hipernatremia durante as primeiras 72 horas de internação na Unidade de Terapia Intensiva. A análise multivariada dos pacientes com hemorragia subaracnoidea pós-ruptura de aneurisma revelou que a mortalidade esteve significativamente associada ao choque séptico e hipernatremia nas primeiras 72 horas de permanência na Unidade de Terapia Intensiva, enquanto o tratamento precoce do aneurisma (clipagem ou embolização endovascular) nas primeiras 72 horas foi identificado como preditivo de um bom prognóstico. Conclusões: Os pacientes com hemorragia subaracnoidea transferidos apresentaram taxas menores de sobrevivência. Choque séptico e hipernatremia foram complicações importantes entre os pacientes gravemente enfermos com hemorragia subaracnoidea e foram associados ao aumento da mortalidade.
