Brief Summary:

Recent research has focused on the investigation of sublingual microcirculatory alterations in different patient categories, like cardiac surgery and sepsis. The microcirculation plays a pivotal role in tissue oxygenation and can be non invasively visualized by sidestream dark field (SDF) imaging.

The objective is to carry out a international multi center study to investigate the prevalence of microcirculatory alterations in intensive care patients. Up to the present time, a comprehensive prevalence study like this has not been carried out.

Condition or disease
Critical Illness

Detailed Description:
Visualization of the sublingual microcirculation at a fixed time point with SDF- or OPS-imaging in all adult patients of participating intensive care units, regardless of their underlying disease. Concurrently, data on both patient characteristics (e.g. severity of illness, treatment) and ICU characteristics will be obtained.

Study Type : Observational
Actual Enrollment : 500 participants
Observational Model: Case-Only
Time Perspective: Cross-Sectional
Official Title: Observation of the Prevalence of Sublingual Microcirculatory Alterations With SDF Imaging in Intensive Care Patients
Study Start Date : September 2011
Actual Primary Completion Date : December 2011
Actual Study Completion Date : May 2012

intensive care patients
no interventions

Primary Outcome Measures :
  1. microcirculatory alterations related to underlying illness, expressed as - amongst others- microvascular flow index (MFI), proportion of perfused vessels (PPV). [ Time Frame: 24 hours ]

Secondary Outcome Measures :
  1. microcirculatory alterations related to: hospital/intensive care length of stay mortality severity of illness [ Time Frame: 28 days ]
