ABSTRACT

Objective:

Cognitive impairment after intensive care unit (ICU) admission is becoming increasingly recognized. High-dose deep sedation has been suggested to play an important role in the development of cognitive impairment. However, the impact of heavy sedation as a single cause in the development of cognitive impairment in ICU patients remains unclear. In this study we investigated whether a three-day deep sedation protocol could reduce cognitive function in mechanically ventilated non-critical patients.

Design:

A prospective observational study was carried out. Patients A total of 17 surgical patients were studied. Intervention None. Variables of interest Cognitive function before and after ICU admission.

Results:

Thirty-one patients requiring three days of sedation after microvascular reconstruction were initially enrolled in the study. Sedation in the ICU was maintained with propofol and dexmedetomidine combined with fentanyl. Cognitive function was assessed using a battery of 6 neuropsychological tests two days before surgery and three weeks after surgery. Finally, a total of 17 patients were included in the analysis. Cognitive impairment (defined as a decline of >20% from the pre-admission cognitive evaluation scores in at least two of 6 tests) was observed in 5 of the 17 patients (29%). However, there were no significant differences between the pre- and post-admission cognitive evaluations in 6 tests.

Conclusions:

Middle-term cognitive function can be impaired in some patients subjected to deep sedation during several days following maxillary-mandibular oral surgery with microvascular reconstruction
RESUMEN

Objetivo:

Cada vez existe un mayor consenso sobre la afectación cognitiva tras el ingreso en la unidad de cuidados intensivos (UCI). Se ha sugerido que la sedación profunda con dosis elevada desempeña un papel importante en el desarrollo de la alteración cognitiva. Sin embargo, todavía existen dudas sobre el impacto de este tipo de sedación como causa única del desarrollo de alteraciones cognitivas en pacientes ingresados en la UCI. En este estudio, investigamos si la aplicación de un protocolo de sedación profunda durante 3 días disminuía la función cognitiva en pacientes no críticos bajo ventilación mecánica.

Diseño:

Se llevó a cabo un estudio observacional prospectivo. Pacientes Se estudió a un total de 17 pacientes quirúrgicos. Intervenciones Ninguna. Variables de interés Función cognitiva antes y después del ingreso en la UCI.

Resultados:

En este estudio se incluyó inicialmente a 31 pacientes que requerían 3 días de sedación tras una reconstrucción microvascular. Se mantuvo la sedación en la UCI con propofol y dexmedetomidina en combinación con fentanilo. Se evaluó la función cognitiva mediante un grupo de 6 pruebas neurofisiológicas antes de la intervención y 3 días después de esta. Por último, se incluyó a un total de 17 pacientes en el análisis. Se observó alteración cognitiva (definida como una reducción>20% frente a las puntuaciones de la evaluación cognitiva previa al ingreso en al menos 2 de las 6 pruebas) en 5 de los 17 pacientes (29%). Sin embargo, no se observaron diferencias significativas entre las evaluaciones previas y posteriores al ingreso en 6 pruebas.

Conclusiones:

La función cognitiva a medio plazo puede verse afectada en algunos pacientes sometidos a sedación profunda durante varios días tras una cirugía oral maxilar-mandibular con reconstrucción microvascular
