Introduction:

The maintenance of an appropriate nutritional state is fundamental in people with respiratory diseases, since malnutrition can cause negative effects in the respiratory system and affect its musculature, the lung parenchyma, as well as the immune system.

Objective:

To determine the prediction charge of the nutritional state when admitted to the institution and the artificial mechanical ventilation on the unfavorable clinical course of patients with acute chronic obstructive lung disease.

Methods:

A descriptive, applied and explanatory study was carried out on 39 patients with acute chronic obstructive lung disease, who were admitted to the Intensive and Intermediate Care Service of Saturnino Lora Torres Teaching Clinical-Surgical Provincial Hospital in Santiago de Cuba, from October, 2022 to November, 2023.

Results:

There was a prevalence of the 65 and over age group (64.1 %); on his arrival at the service, 24.1 % of the patients presented altered albumin, 56,4 % was undernourished and invasive mechanical artificial ventilation prevailed (53.8 %). The deficiency malnutrition on admission constituted a significant causal factor (p = 0.029) with unfavorable clinical course in those affected and exposed to this risk [OR = 6.22; I.C 95%: 1.21; 32.02].

Conclusions:

This study indicated that malnutrition on admission of the patients with acute chronic obstructive lung disease constitutes a prediction factor of unfavorable clinical course.
