Análisis del rendimiento y la eficacia del socorrista acuático sin y con material de rescate

Abstract

El propósito de esta tesis doctoral es analizar el rendimiento y la eficacia del socorrista acuático profesional (rescate + RCP durante 5 minutos) sin y con material de rescate (MARPA y aletas). Para ello se han estudiado a 20 socorristas profesionales, 10 hombres y 10 mujeres. Se testaron dos rescates, uno sin material y otro con material de rescate (MARPA y aletas), analizándose variables temporales (duración total de rescate), fisiológicas (frecuencia cardiaca y concentración de lactato) y psicológicas (escala de Borg). Para el análisis de la RCP, se realizó un primer test en reposo durante 5 minutos para compararlo posteriormente con la RCP durante otros 5 minutos después de los rescates (sin y con material), analizándose variables en cuanto a la calidad de la RCP (compresiones y las ventilaciones). Se utilizó el Lactate Scout para conocer la concentración de ácido láctico en sangre in situ, la Escala de Borg modificada, para conocer la percepción del esfuerzo de toda la prueba, y el maniquí Laerdal Resusci Anne® para registrar la calidad de la RCP (compresiones y ventilaciones). Los datos obtenidos muestran que en la prueba con material se reduce la concentración de lactato al finalizar la RCP (LacRCP1: p=0,006; LacrRCP3: p=0,030; LacrRCP5: p=0,059), y también se reduce de manera significativa el tiempo total de intervención (p=0,004) con respecto a la prueba sin material. En cuanto a la RCP se encuentran diferencias estadísticamente significativas en el porcentaje de compresiones correctas entre las tres pruebas de RCP realizadas (p=0,002). En cuanto al porcentaje de ventilaciones correctas, se ventila mejor en reposo (p=0,001) que en las pruebas con o sin material, aunque no se consideran ventilaciones de calidad ya que no llegan al 70% de efectividad. Por lo tanto, se concluye que el uso de material de socorrismo (MARPA y aletas) reduce la duración del rescate acuático, disminuye el estrés fisiológico del rescate y equipara el nivel condicional del socorrista y, por último, que un rescate acuático provoca un decremento de la calidad de la RCP provocada por la fatiga.

The aim of this doctoral thesis is to analyze the performance and effectiveness of professional lifeguards (rescue + CPR for 5 minutes) with and without rescue equipment (MARPA and fins). 20 professional rescuers, 10 men and 10 women, has been studied. Two rescues were tested, one without equipment and other one with rescue material (MARPA and fins). Temporal (total duration of the rescue), physiological (heart rate and lactate concentration) and psychological (Borg scale) variables were analyzed. For CPR analysis, a first test is performed at rest for 5 minutes for later comparison with the CPR for a further 5 minutes after the rescue (without and with the material), analyzing the quality of CPR (compressions and vents). The Lactate Scout was used to determine the lactic acid concentration in blood; the modified Borg Scale, for the perceived effort of the entire test; and the Laerdal Resusci Anne ® manikin to recording quality of CPR (compressions and vents). The data show that lactate concentration is reduced at the end of the CPR (LacRCP1: p=0.006; LacrRCP3: p=0.030; LacrRCP5: p=0.059) in the test with material and also significantly reduces the total time intervention (p=0.004) respect to the test without material. In the CPR are statistically significant differences in the percentage of correct compression between the three CPR tests performed (p=0.002). Regarding to the percentage of correct ventilation, ventilation at rest is better (p=0.001) than in the tests with or without material, although not reach the 70% effective, so is not considered as correct vents. Therefore it is concluded that the use of lifesaving equipment (MARPA and fins) reduces the water rescue duration, it reduces the physiological rescue stress and it equates lifeguard conditional level, and finally, a water rescue causes a decrease in the quality of the CPR-induced fatigue.
