Resumen
Objetivo: Verificar los efectos de la posición prono en pacientes con Síndrome de Distrés Respiratorio Agudo causado (SDRA) por COVID-19, investigando datos epidemiológicos, clínicos y de laboratorio. Métodos: Se trata de un estudio longitudinal y retrospectivo, realizado en un hospital filantrópico de la región noroeste del estado de Espírito Santo. Se incluyeron en el estudio 33 pacientes con diagnóstico de SDRA secundario a COVID-19, en ventilación mecánica invasiva, prono dos veces durante su estancia en la unidad de cuidados intensivos de adultos, ingresados desde junio de 2020 hasta febrero de 2022. Se utilizó el test de Shapiro de Wilk y Mann- Prueba de Whitney para comparar los dos grupos. Resultados: Hubo una reducción en el valor de PaO2 de 17,03 a 13,80; (p=0,220) y SatO2 4,11 – 2,67; (p=0,162) y aumento de FiO2 -0,14 - -0,01; (p=0.006) en la muestra evaluada. También destaca la reducción del ratio PaO2/FIO2 49,05 – 30,77; (p=0,093), sin significación estadística. Hubo aumento en el parámetro ventilatorio de PEEP -0,30 – 0,12; (p=0,434). Conclusión: Se concluye que la posición prona influyó en el suministro de la fracción inspirada de oxígeno – FiO2, con valor estadísticamente significativo, y no hubo mejoría significativa en los índices PaO2/FiO2, SatO2 o PaO2. Además, se observó un aumento en los valores de lactato.
