Introduction:

the presence of mechanical ventilation brings about questions related to the importance of knowing the influence of the nutritional status and its relation with risks factors.

Objective:

to establish a relationship of the nutritional status according to grouped anthropometric indicators with laboratory, clinical and socio-demographic variables that were studied in artificially ventilated patients when admitting them in the Intensive Care Unit of the University Hospital “Celia Sánchez Manduley”, during 2017 and 2018.

Materials and method:

a cohort, prospective, analytical, observational study was carried out with patients who fulfilled the inclusion criteria. Different techniques of descriptive statistics were used, together of with measures of central tendency and dispersion. The level of significance was determined according to value p ≤ 0,05 by means of Pearson's Chi Squared (X2) and the student T test.

Results:

male sex and ages over 60 years were significantly associated to malnutritioned ventilated patients. Measuring isolated biochemical indicators was not significantly useful to assess nutritional status in these patients.

Conclusions:

comorbidity, nosocomial infections, average lasting ventilation, and neurological clinical entities predominated, with high mortality at discharging, but without significant association to the nutritional status.
