    Evacuating people in acute renal failure by air is difficult because the hazards of fluid overload and anaemia are potentiated by altitude. In two such patients continuous arteriovenous haemofiltration was used to control their fluid problems during aeromedical evacuation. In the first case, a patient with renal failure and blast lung, haemofiltration was performed at 500 ml/h over a four hour journey; in the second, a woman with severe pre-eclamptic toxaemia who developed acute renal failure after caesarean section, haemofiltration was performed at 200 ml/h over a 14 hour flight. Both patients recovered fully. In these two cases haemofiltration permitted control of the intravascular volume during aeromedical evacuation. The technique represents a major advance in the safe transfer of casualties.
