[Formaldehyde sediment in incubators following disinfection].
Measurements in incubators revealed the presence of formaldehyde concentrations involving a health risk for premature and normal newborns kept and cared for in incubators. Prior to measurements, the incubators had been disinfected by means of formaldehyde vapours in an "Aseptor" disinfecting cabinet (Drägerwerk AG, Lübeck) and then ventilated in strict adherence to operating instructions. The elevated formaldehyde concentrations found had been due to residues of paraformaldehyde and urotropin on the surfaces of the disinfected apparatus, liberating formaldehyde by hydrolysis depending on temperature and relative humidity. There should be a basic reconsideration of the present practice of incubator disinfection. From experiments with activated-carbon filters in incubators it would seem that there is a chance of reducing such formaldehyde concentrations.
