| Popis: | The incidence of sudden infant death syndrome (SIDS) has declined in response to campaigns discouraging the prone sleeping position. Recent work suggests some SIDS death may be in response to bacterial toxins produced in the upper airway. A minimal temperature of 37 degrees C is required for induction of the pyrogenic toxins of Staphylococcus aureus identified in many SIDS infants. This aim of this study was to test the hypothesis that the prone position raises the temperature of the upper airways in children. A pilot study of 10 children (aged 3-8) and a main study of 30 children were carried out. Nasal septal temperatures were measured with an infra-red thermometer with the subjects in upright and prone positions under controlled conditions of ambient temperature and humidity. In both the pilot study and main study, nasal temperatures in the prone position were significantly higher (P0.01) Five subjects' prone readings were 37 degrees C or higher. These findings suggest that lying prone raises the upper airway surface temperature towards that required for toxin production. This could be one means by which the prone sleeping position contributes to the risk of SIDS. |
