Clinical study of Dysfunctional Ventilatory Weaning Response in critically ill patients

Objective: to clinically validate the nursing diagnosis of Dysfunctional Ventilatory Weaning Response in adult patients admitted to Intensive Care Units. Method: a concurrent cohort performed with 93 patients admitted to Intensive Care Units. The incidence and incidence density of the diagnosis were estimated, its related factors were identified based on bivariate analysis and clinical indicators for determining its occurrence, according to the global and temporal presentation. Results: the overall incidence of the diagnosis was 44.09% and the incidence density was 14.49 occurrences for every 100 extubations/day. The factors related to the diagnosis were the following: age, clinical severity, fluid balance, oliguria, hemodialysis, edema in upper/lower limbs, anasarca, number of antibiotics, hypothermia, hyperthermia, amount of secretion, muscle retraction, anxiety score, heart rate, use of vasopressors and non-invasive ventilation after extubation. The clinical indicators most frequently identified for determining the diagnosis were the following: tachypnea, drop of saturation and tachycardia. Temporal progression in the severity of these manifestations was found. Conclusion: the Dysfunctional Ventilatory Weaning Response is a common finding in critically ill patients. Some components of the diagnosis of the NANDA-International (2018) version could be clinically validated. It is noteworthy that there are variables not yet described in the taxonomy, demonstrating the need to review this nursing diagnosis.

Método: cohorte concurrente realizada con 93 pacientes internados en Unidades de Cuidados Intensivos. Se estimó la incidencia y densidad de incidencia del diagnóstico y se identificaron los factores vinculados a partir de análisis bivariados e indicadores clínicos para determinar su ocurrencia, de acuerdo con la presentación global y temporal. Resultados: la incidencia global del diagnóstico fue de 44,09% y la densidad de incidencia de 14,49 casos por cada 100 extubaciones/día. Los factores relacionados con el diagnóstico fueron: edad, gravedad clínica, balance hídrico, oliguria, hemodiálisis, edema en miembros superiores/inferiores, anasarca, número de antibióticos, hipotermia, hipertermia, cantidad de secreción, retracción muscular, grado de ansiedad, frecuencia cardíaca, uso de vas
