[More precise indications for fluid therapy during transportation to hospital are required].

Although early intravenous fluid therapy for haemorrhage and shock is usually given before arrival at the hospital, its value is unclear and more precise indications are needed. The indications will take into account such factors as transport time, volume and type of bleeding, and the presence or absence of concomitant head injury. Fluid resuscitation can be omitted if transport time is less than 30 min, but may be beneficial if it is more than 30 min. Choice of infusion rate should be guided by the estimated risk of re-bleeding when haemorrhage is uncontrolled, and by cerebral perfusion where severe head injury is present.
