Abstract
WILCHES-LUNA, Esther and ARZAYUS, Leonardo. Relationship between handgrip strength and inspiratory muscles with the success of the spontaneous breathing trial. Rev. Univ. Ind. Santander. Salud [online]. 2023, vol.55, e13. Epub Nov 21, 2023. ISSN 0121-0807. https://doi.org/10.18273/saluduis.55.e:23066.
Introduction:
In critically ill patients on mechanical ventilation, the loss of inspiratory and peripheral muscle strength is associated with prolonged mechanical ventilation and failed weaning.
Objective:
To determine the relationship between handgrip strength and inspiratory muscle strength with the success of the Spontaneous Breathing Trial in adults with ventilatory support greater than 48 hours.
Methodology:
Prospective observational cross-sectional study performed at a tertiary hospital in Colombia. Handgrip strength and Maximal Inspiratory Pressure were measured once a day before Spontaneous Breathing Trial testing. Pearson's test and Cohen's D test were used to analyze correlations.
Results:
A total of 51 patients were included, 57% male, with a mean age of 51.9±20 years. A positive correlation was identified between Maximal Inspiratory Pressure and grip strength; and a negative correlation between grip strength and Maximal Inspiratory Pressure with the days of stay in the intensive care unit, (r -0.40; p<0.05) and (r -0.45; p<0.05).
Conclusions:
Handgrip strength and Maximal Inspiratory Pressure were positively correlated with Spontaneous Breathing Trial success. The importance of these measures to guide ventilator disconnection processes is highlighted.
