Pregnant women & those contemplating pregnancy need special consideration because of specific nature of the potential health hazards of long distance flights.These include exposure to cosmic radiation, reduced arterial oxygen pressure, immobilization & unforseen medical & obstetrical emergencies encountered during flight.
More radiation shielding is provided by atmospheric air at lower altitudes.The dose received from cosmic radiation is usually lower during short haul flight since long haul flight are usually flown at higher altitudes.The changes in heart rate & BP which are associated with decreased partial oxygen pressure may affect women with compromised pregnancies.
Increased risk of venous thrombosis may occur due to prolonged immobilization from cramped seats, which is called Economy class syndrome.
1. Pregnant women should use their seat belts continuously while seated.
2. Long distance flights are not recommended for women upto 36 wks gestation with singleton pregnancy & 32 wks with multiple pregnancies.3. Travellers should be updated on routine immunizations including TT,Diptheria, Influenza, & other immunization based on geographic risk
