[Value of HME antibacterial filters in neonatal and pediatric anesthesia. Comparison with traditional heating humidifiers].

HME (heat-moisture exchangers) filters (Hygrobaby DAR) have been compared with classical humidifiers (Bennett Cascade Humidifier) with regard to heating and humidification of inspired gases in anaesthetized neonates and infants. 28 young patients (2 days-12 months) have been randomized into two groups. Though traditional heaters-humidifiers offer slightly higher performances in terms of temperature and moisture, HME-filters appear to be a better choice from cost, handiness and safety considerations. Antibacterial efficacy of HME-filters is also a major quality.
