Sea water solution could be used to treat colds in children

  • Comment
A saline nasal wash solution made from processed sea water could be used to treat children with colds, a study has shown.
The research conducted in the Czech Republic randomly assigned 401 children aged six to 10 with cold or flu to two treatment groups, one receiving standard medication and the other receiving a nasal wash with a modified processed sea water solution.

After eight weeks, 9% of children in the nasal wash group were using fever-reducing drugs, compared with 33% on standard medication.

There were also fewer children in the sea water solution group using nasal congestants (5% vs 47%), mucus dissolving medications (10% vs 37%) or antibiotics (6% vs 21%).

Fine spray formulations were the best tolerated form of the nasal wash, according to the researchers.
The authors postulated that washes may work by reducing the production of inflammatory compounds, or be creating a favourable environment for fine hairs in the immune system to sweep away mucus and particles.
