Delirium in ICU patients following cardiac surgery: An observational study.

AIMS AND OBJECTIVES: To observe the clinical and structural factors that can be associated with the post-operative onset of delirium in patients who have undergone heart surgery. BACKGROUND: Several risk factors could contribute to the development of delirium, such as the use of some sedative drugs and a patient's history with certain types of acute chronic disease. However, in the literature, there is little knowledge about the association between delirium in patients who have undergone cardiac surgical intervention and their clinical and environmental predictors. DESIGN: We used an observational design. METHODS: We enrolled 89 hospitalised patients in the ICU. Patients were first evaluated using the Richmond Agitation Sedation Scale and subsequently using the Confusion Assessment Method for the ICU. A linear model of regression was used to identify the predictors of delirium in patients. RESULTS: The patients had an average age of 89 years (SD = 6.9), were predominantly male (84.3%) and were mostly married (79.8%). The majority of patients had been subjected to bypass (80.9%), while 19.1% had undergone the intervention of endoprosthesis. The logistic regression model showed that patient age, the duration of mechanically assisted ventilation, continuous exposure to artificial light and the presence of sleep disorders were predictors of the onset of delirium. CONCLUSION: This study further confirms that clinical aspects such as insomnia and one's circadian rhythm as well as structural elements such as exposure to artificial light are variables that should be monitored in order to prevent and treat the onset of severe post-operative delirium. RELEVANCE TO CLINICAL PRACTICE: Identifying the possible factors that predispose a patient to the onset of delirium during intensive therapy following cardiac surgery, it is fundamental to implement interventions to prevent this syndrome.

The lived experiences of the parents of children admitted to a paediatric cardiac intensive care unit.

BACKGROUND: Congenital heart disease is a common birth defect rather than a paediatric disease. Parents often discover this disease after their children's birth and then often learn that cardiac surgery is the only solution. A child's admission to a paediatric cardiac intensive care unit (PCICU) may lead to high levels of stress, anxiety and depression in parents. OBJECTIVES: To describe the lived experiences of mothers and fathers during their children's confinement in a PCICU. METHODS: A phenomenological study was conducted. This method combines descriptive features (Husserlian) and interpretive phenomenology (Gadamerian). The subjects were interviewed with open questions to allow them full freedom of expression and were asked to describe their experiences when their children were admitted to the PCICU. Each interview was audio-recorded and lasted between 20 and 60 minutes. The researchers involved in the analysis each independently immersed themselves in the data by reading and re-reading the transcripts in order to gain a sense of the whole dataset. The extrapolation of the themes followed. The individual researchers compared the various extrapolated themes. RESULTS: We enrolled 16 participants. Three main themes emerged: 1) the fear of the potential loss of their children, (2) the feeling of having lost their roles as parents and (3) the desire to receive more information and be an active part of the treatment process. CONCLUSION: A child's admission to a PCICU requires healthcare staff to take care of the child's family members as well. Knowing about mothers' and fathers' experiences is crucial in implementing a holistic and multidisciplinary process of care.
