Insights
Critically ill children in pediatric intensive care units (PICUs) sleep poorly, averaging only 4.7 hours per night. Environmental factors like noise, light, and caregiver contact significantly disrupt their sleep patterns.
Area of Science:
- Pediatric critical care medicine
- Sleep science
- Environmental health
Background:
- Sleep is crucial for physical and psychological health in children.
- Limited research exists on pediatric intensive care unit (PICU) sleep and its influencing factors.
Purpose of the Study:
- To observe and quantify sleep in children within a PICU setting.
- To identify relationships between environmental factors and sleep quality in PICU patients.
- To assess the impact of parental presence and illness severity on PICU sleep.
Main Methods:
- Observational study with 5-minute intervals over 10 hours (8 PM to 6 AM).
- Recorded sleep state, noise levels (dB(A)), light intensity, caregiver contact, and parental presence.
- Measured illness severity upon admission and within 26 hours of data collection.
Main Results:
- Children slept an average of 4.7 hours, with 9.8 awakenings per night.
- Average sleep episode length was 27.6 minutes.
- Noise (mean 55.1 dB(A), peaks to 90 dB(A)), light, and caregiver contact were significant predictors of sleep; parental presence and illness severity were not.
Conclusions:
- PICU patients experience significantly reduced sleep duration and disturbed sleep patterns compared to age-matched norms.
- Environmental factors (noise, light) and caregiver interactions are key modifiable factors influencing sleep.
- Healthcare professionals can optimize the PICU environment and care practices to promote sleep in critically ill children.
Background:
Although sleep is important for physical and psychological health, no research has assessed the sleep of children in a pediatric ICU and the factors that affect sleep.
Objectives:
To observe the sleep of children in a pediatric ICU and to determine the relationship of noise, light, contact with caregivers, parental presence, and severity of illness to the sleep obtained by children in a pediatric ICU during a 10-hour night.
Methods:
At 5-minute intervals from 8 PM until 6 AM, a convenience sample of nine patients was observed. Sleep state, noise and light levels, contact with caregivers, and parental presence were recorded. Severity of illness was measured on admission and within 26 hours of data collection.
Results:
Subjects slept for a mean total of 4.7 hours (SD = 0.49) during the 10-hour night, interrupted by a mean of 9.8 awakenings (SD = 2.48). The mean length of a sleep episode was only 27.6 minutes (SD = 25.85). Mean noise level was 55.1 dB(A) (SD = 6.82), with sudden, sharp elevations of up to 90 dB(A). Probit analysis indicated that noise, light, and contact with caregivers were significant predictors of sleep. Parental presence and severity of illness were not.
Conclusions:
Patients in the pediatric ICU sleep significantly less than is normal for children of the same ages, and their patterns of sleep are seriously disturbed. Because noise, light, and contact with caregivers are significant predictors of sleep state, health professionals can use these findings to structure the environment and the care they give to promote the sleep of critically ill children.
