Whole-body cooling in neonatal encephalopathy using phase changing material
Statistics from Altmetric.com
Whole body cooling improves outcomes after neonatal encephalopathy (NE) in high-income countries1; however, effective low technology cooling devices suitable for use in low and middle-income countries (LMIC) is lacking.2 Although cooling using ice is effective in tertiary neonatal units, dangerous temperature fluctuations may occur if continuous temperature monitoring and nursing support is not available.2 Phase changing materials (PCM) are made of salt hydride, fatty acid, and esters or paraffin, and melt at a set point; in the process they can store or release large amounts of energy (figure 1). We examined the feasibility of administering whole body cooling using PCM.
