Conditions
Brief summary
Sleep, controlled by the sleep homeostat and the circadian clock, is essential. In the hospital environment, sleep can be disrupted. This disruption may be attributable to an effect on the sleep homeostat, the circadian clock, or both. The consequences of sleep disruption due to hospitalisation, surgery and anaesthesia may include delayed post-operative recovery. Here, we measure sleep/ wake cycles, mood states and two different markers of circadian rhythms in a surgical population to determine any changes that may occur in the hospital environment.
Interventions
Patients undergoing cardiac surgery have their sleep/ wake cycles actigraphically measured, their core body temperature rhythms and salivary melatonin measured and recorded and their mood assessed. This takes place in three seperate stages, each a week long. They are monitored pre-operatively, post-operatively in hospital and post-discharge.
