Delirium Associated with Assisted Mechanical Ventilation in Critical Care Unit
Keywords:
intensive therapy, mechanical ventilation, deliriumAbstract
Objective: Establish the prevalence of delirium and identify predictors and mortality in the ICU of the San Gerónimo Private Sanatorium of Santa Fe, Argentina.
Methods: A cross-sectional descriptive study in ICU patients, requiring MV and a delirium diagnosis. The Richmond Agitation Sedation Scale (RASS) and the CAM-ICU were used to identify delirium. The variables studied were the medical record, variables attributed to the hospitalization and MV, and type of delirium. The SPSS® statistical analysis program was used.
Results: The prevalence of delirium was 93% of MV patients. It was classified as 58% hypoactive and 42% hyperactive. The mortality detected is 80%. No significant relationship was found between the type of delirium and age (p=0,722), sex (p=0,828), or the pathology that led to MV. No statistically
significant data were obtained on risk factors, days of total MV, hospital stay, sedoanalgesia, use of corticosteroids/neuroleptics, or admission scores, regarding mortality.
Conclusions: According to the data obtained, the prevalence of delirium associated with MV in SPSG is high, being closely associated with mortality, and not obtaining a relationship with the risk factors studied. We consider early detection necessary, as it influences days of MV and, consequently of hospitalization and mortality.
