Søvn- og delir etter utskifting av aortaklaff blant eldre pasienter

Søvnforstyrrelser og delir forekommer ofte etter operasjon ved utskifting av aortaklaff, spesielt hos eldre pasienter. Forskere fra Haukeland universitetssjukehus, Jönköping universitet, Linköping universitet, Linné universitetet og Universitetet i Bergen har i denne studien undersøkt eldre pasienter (80 år+) sine erfaringer med postoperative søvnforstyrrelser og delir etter utskifting av aortaklaff. 10 pasienter ble intervjuet 6-12 måneder etter behandling med fokus på forvirring. Fem av disse pasientene ble intervjuet 4 år etter behandlingen, med fokus på søvnsituasjonen. Resultatene viste at denne pasientgruppen plages av søvnforstyrrelser og delir i lang tid etter operasjonen, og at dette bør få mer fokus for å bedre pasientbehandlingen.

Objectives: Sleep disturbances and delirium are frequently observed complications after surgical aortic valve replacement (SAVR) and transcutaneous aortic valve implantation (TAVI), especially in octogenarian patients. However, a knowledge gap exists on patient experiences of sleep and delirium. In particular, patients' long-term sleep and delirium experiences are unknown. This article explores and describes how octogenarian patients suffering from delirium after aortic valve replacement experience their sleep and delirium situation.
Design: An explorative and descriptive design with a longitudinal qualitative approach was applied. Qualitative content analysis following the recommended steps of Graneheim and Lundman was performed.
Setting: Patients were included at a tertiary university hospital with 1400 beds. Delirium and insomnia screening was performed at baseline and five postoperative days after aortic valve treatment. For qualitative data, 10 patients were interviewed 6-12 months after treatment with focus on delirium. Five of these patients were reinterviewed 4 years after treatment, with focus on their sleep situation.
Participants: Inclusion criteria; age 80+, treated with SAVR or TAVI and had experienced delirium after treatment.
Results: For the initial interview, we included five men and five women, four following TAVI and six following SAVR, mean age 83. One overarching theme revealed from the content analyses; Hours in bed represented emotional chaos. Whereas three subthemes described the patients' experiences with sleep and delirium, a cascade of distressful experiences disturbing sleep, the struggle between sleep and activity and elements influencing sleep. Four years after the treatment, sleep disturbances persisted, and patients still remembered strongly the delirium incidences.
Conclusions: For octogenarian patients, sleep disturbances and delirium are long-term burdens and need a greater attention in order to improve patient care.
