Bathing premature infants: physiological and behavioral consequences
1Faculty of Nursing, University of Alberta, Edmonton, Canada.
Insights
Routine sponge baths negatively impact preterm infants, causing physiological and behavioral distress. These findings suggest that this common neonatal intensive care unit (NICU) procedure should be avoided for ill premature infants.
Area of Science:
- Neonatal care
- Pediatric physiology
- Infant behavior
Background:
- Routine procedures are common in neonatal intensive care units (NICUs) but can adversely affect preterm infants' growth and development.
- Despite known risks, these routine procedures persist in NICU care.
- The physiological and behavioral impact of a seemingly benign procedure, sponge bathing, on premature infants requires investigation.
Purpose of the Study:
- To assess the physiological and behavioral effects of routine sponge baths on premature infants.
- To compare infant responses during pre-bath, bath, and post-bath phases.
Main Methods:
- A prospective, quasi-experimental study involving 14 preterm neonates (28.1–31.8 weeks postconception).
- Each infant served as their own control, with continuous monitoring of oxygen delivery, heart rate, oxygen saturation, and behavior.
- Data collected across baseline, bath, and post-bath phases.
Main Results:
- Sponge bathing led to significant physiological disruptions, including increased heart rate and oxygen demand.
- Decreased oxygen saturation and increased need for supplemental oxygen were observed in most infants.
- Behavioral responses showed significant motoric cue frequency and timing associated with physiological changes.
Conclusions:
- Routine sponge bathing causes significant physiological and behavioral distress in ill premature infants.
- The findings challenge the assumption that routine care is harmless to neonates.
- Sponge bathing is not recommended for the care of ill premature infants in the NICU.
Background:
Routine procedures are a large component of the caretaking day for preterm infants. Such procedures can have profound adverse effects on an infant's condition, to the point of disrupting normal growth and development. Despite this evidence, routine procedures are perpetuated in the neonatal ICU.
Objective:
To determine the physiological and behavioral effects of a supposedly beneficial procedure, a sponge bath, on premature infants.
Methods:
The study sample consisted of 14 preterm neonates with no neurological abnormalities at two tertiary neonatal ICUs. The ages of the subjects were 28.1 to 31.8 weeks postconception and 4 to 25 days after birth. The study was a prospective, quasi-experimental, repeated-measures design in which each infant acted as his or her own control. Oxygen delivery, heart rate, oxygen saturation, and behavioral responses were continuously recorded by computer or real-time videotape. Physiological and behavioral parameters were compared across three phases: 10 minutes before a bath (baseline), during a standardized bath, and 10 minutes after the bath.
Results:
Physiological and behavioral disruptions occurred throughout the bath phase and in many cases beyond that phase. These disruptions included significant increases in heart rate, cardiac oxygen demand, and frequency of behavioral motoric cues. Significant decreases in oxygen saturation also accompanied the bath. Nine infants required increased concentrations of ambient oxygen. A significant association was found between physiological components and the frequency and timing of behavioral motoric cues.
Conclusions:
The results provide further evidence that routine care is not innocuous to neonates. Routine sponge bathing is not recommended for care of ill premature infants.
