Description

There is a tremendous amount of burden on families who take care of home-care patients (children) requiring medical care. We investigated influence of patient mothers’ conducting medical care at nighttime on their autonomic nerve activities during sleep. The subjects of this study included mothers who had been taking care of patients (children) with physical handicaps and multiple severe disabilities aged between 6 - 24 with Type 1 and Level 1 physically disabled persons’ certificate. Using an activity measurement device with a built-in photoelectric plethysmograph, we measured pulse intervals and the amount of activities of subjects between 8:00 p.m. and 8:00 a.m. for 3 days, and calculated the time when they fell asleep/woke up, hours of sleep, and the number of times and duration of awakening during sleep. In addition, we calculated low frequency (LF) and high frequency (HF) as well as LF/HF during sleep from the time when they fell asleep/woke up and investigated relationships between the autonomic nerve activities and sleep conditions, presence or absence of medical care, and feeling of burden in the home-care setting. Positive correlations were observed between LF/HF and the number of times/duration of awakening during sleep. The number of times and duration of awakening and LF/HF were significantly high in mothers who had been conducting intratracheal aspiration. Moreover, there was a tendency that the higher the number of aspiration, the more LF/HF was elevated. Awakening for intratracheal aspiration after they fell asleep and elevation of LF/HF were observed in family members who had been conducting intratracheal aspiration, suggesting that they might not have been resting well physically and physiologically during sleep.
