Summary
Phase changing material (PCM) offers a cost-effective method for therapeutic hypothermia in hypoxic ischaemic encephalopathy (HIE). This approach maintains stable temperatures, reducing the need for interventions and costly equipment.
Area of Science:
- Neonatal care
- Pediatric neurology
- Medical device innovation
Background:
- Therapeutic hypothermia is effective for hypoxic ischaemic encephalopathy (HIE).
- Standard cooling equipment is expensive.
- Ice packs are labor-intensive and cause temperature fluctuations in low-resource settings.
Purpose of the Study:
- To evaluate the feasibility of using phase changing material (PCM) for therapeutic hypothermia.
- To assess PCM as a low-cost alternative to standard equipment.
Main Methods:
- Retrospective analysis of 41 infants with HIE cooled using PCM (OM 32 or HS 29).
- Target rectal temperature: 33-34°C, continuously monitored.
- Interventions (gel packs or warming) applied based on temperature deviations.
Main Results:
- Mean temperature during cooling: 33.45 ± 0.26°C.
- Target temperature range maintained 96.2% of the time.
- No temperature readings below 32°C; HS 29 eliminated ice pack use.
Conclusions:
- PCM is a low-cost, effective method for maintaining therapeutic hypothermia.
- Careful monitoring is crucial during induction and rewarming to prevent hypothermia outside the therapeutic range.

1.2K
A decreased body temperature can occur in patients with hypothermia and frostbite. Heat loss with extended cold exposure overpowers the body's ability to create heat, resulting in hypothermia. Core temperature readings help classify hypothermia. Mild hypothermia is temperatures between 32 °C (89.6 °F) and 35°C (95 °F) and is caused by impaired thermoregulation. Moderate hypothermia is temperatures between 28 C (82.4 °F) and 32 °C (89.6 °F) caused by...

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.
