[High altitude sojourn in pregnancy and childhood].
Knowledge about the safety of travel to high or moderate altitude during pregnancy or with small children is limited. Previous recommendations restricting travel during pregnancy to an altitude of 2133 m a.s.l. may be too cautious; however, not enough research has been done to allow any recommendation based on scientific evidence. Infants and children generally do well at moderate altitude (< 3000 m a.s.l.), if ascent is gradual and if the child is watched closely for any developing signs or symptoms of acute mountain sickness or high-altitude pulmonary edema. Infants of residents of low altitude may develop right-heart failure due to excessive pulmonary artery hypertension when exposed to altitudes more than 3500 m a.s.l. over several months (subacute mountain sickness).
