MARTIN-RODRIGUEZ, Francisco. Metabolic fatigue in resuscitators using personal protection equipment against biological hazard. Invest. educ. enferm [online]. 2019, vol.37, n.2, e04. ISSN 0120-5307. https://doi.org/10.17533/udea.iee.v37n2e04.
Objective.
To describe the effects of wearing individual protection equipment against biological hazard when performing a simulated resuscitation.
Methods.
Uncontrolled quasi-experimental study involving 47 volunteers chosen by random sampling stratified by sex and professional category. We determined vital signs, anthropometric parameters and baseline lactate levels; subsequently, the volunteers put on level D individual protection equipment against biological hazard and performed a simulated resuscitation for 20 minutes. After undressing and 10 minutes of rest, blood was extracted again to determine lactate levels. Metabolic fatigue was defined as a level of lactic acid above 4 mmol/L at the end of the intervention.
Results.
25.5% of the participants finished the simulation with an unfavorable metabolic tolerance pattern. The variables that predict metabolic fatigue were the level of physical activity and bone mass -in a protective form- and muscle mass. People with a low level of physical activity had ten times the probability of metabolic fatigue compared to those with higher levels of activity (44% versus 4.5%, respectively).
Conclusion.
Professionals who present a medium or high level of physical activity tolerate resuscitation tasks better with a level D individual biological protection suit in a simulated resuscitation.
