What room temperature should be maintained during the period of phototherapy?

Appeared in: BHU NO-2019

Explanation

Phototherapy requires the neonate to be undressed, which increases the risk of temperature instability.
A thermoneutral environment is crucial to minimize the baby's energy expenditure on maintaining body temperature.
The recommended ambient temperature during phototherapy is 25°C to 28°C to prevent both hypothermia and hyperthermia.
The range of 26-28°C falls squarely within this guideline, balancing heat loss from exposure with heat gain from the phototherapy unit.
This temperature helps maintain the neonate's core body temperature within the normal range (36.5°C to 37.5°C).

Option A: This temperature range is generally too cool for a naked neonate, increasing the risk of cold stress and hypothermia.
Option B: This range is too high. Combined with the heat generated by phototherapy lights, it would almost certainly lead to hyperthermia, dehydration, and increased metabolic stress.
Option C: This temperature range is on the higher side and increases the risk of hyperthermia, especially when the heat output from the phototherapy unit is significant.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Thermoregulation in neonates during phototherapy as background academic context rather than a clinical decision trigger.
Nurses play a critical role in maintaining thermoregulation during phototherapy by monitoring the infant's temperature every 2-4 hours and adjusting the environment as needed.
Accurate temperature control is a key patient safety measure, as both hypothermia and hyperthermia can increase morbidity and mortality in neonates.
Nurses must also monitor for signs of dehydration (e.g., decreased urine output, dry mucous membranes, sunken fontanelle) which is a common side effect of phototherapy.

How to Approach the Question

First, identify the keywords in the question: 'room temperature' and 'phototherapy'.
Recall the physiological principles of neonatal care. Newborns, especially when undressed, have difficulty regulating their body temperature.
Analyze the procedure. Phototherapy requires the baby to be naked, which promotes heat loss.
Consider the equipment. Phototherapy lights produce heat, which can cause overheating.
The correct answer must be a temperature that balances these two opposing risks: preventing the baby from getting too cold while also preventing them from getting too hot.
Evaluate the options: 24-26°C is likely too cold. 30-32°C and 28-30°C are likely too warm. The moderate range of 26-28°C is the most logical choice for creating a thermoneutral environment.
