Intra-abdominal hypertension, diagnosed either with IAP(max) or IAP(mean), was frequent and showed an independent association with mortality. Intra-abdominal hypertension was significantly associated with more severe organ failures, particularly renal and respiratory, and a prolonged intensive care unit stay.

Acute respiratory distress syndrome was a frequent syndrome in this cohort. Sepsis was its leading cause, and pneumonia was the most common single diagnosis. Mortality was high but similar to most recent series that included serious comorbidities. Independent predictors of death 72 hrs after admission emphasize the importance of both extrapulmonary and pulmonary factors together with preexisting severe illnesses.

Colistin appears to be as safe and as effective as other antimicrobials for treatment of sepsis caused by Acinetobacter and Pseudomonas in critically ill patients.

In a heterogeneous ICU population, an abnormal microvascular flow index was present in 17% of patients. This was not associated with mortality. However, in patients with tachycardia, an abnormal microvascular flow index was independently associated with an increased risk of hospital death.
