- Collected quantitative data on skin recoil time, capillary refill time, and skin temperature.
- Identified areas for improvement before clinical application.
Conclusions:
- Optical sensors show promise for objective, non-invasive infant dehydration assessment.
- Further research and development are required to overcome current limitations.
- Potential to improve diagnostic accuracy in resource-limited settings.
Abstract:
Dehydration resulting from acute diarrhea is one of the leading causes of infant mortality in the developing world. Safe assessment of an infant's hydration level is essential to determine appropriate clinical intervention strategies. However, clinical hydration scales, which are the current gold standard for non-invasive hydration assessment, are often unreliable in lower resource settings. This study presents the development and testing of non-invasive, optical sensors for the objective assessment of dehydration based on the quantitative measurement of skin recoil time, capillary refill time and skin temperature. The results obtained have demonstrated the basic feasibility of using optical sensors for the objective assessment of dehydration. However, several challenges must be overcome before these sensors can be applied in a clinical setting.
