Plain English Summary
Background and study aims:
When a person is badly injured and there is significant loss of blood, one of the most important strategies for aiding recovery is to replace the lost volume of blood with suitable intravenous fluid (fluid resuscitation). There is considerable controversy regarding the nature of the fluid that should be used. Simple salt solutions (crystalloids) are widely used and are recommended on the basis that they are cheap and have few side effects. On the other hand, more complex solutions containing large molecules (colloids) designed to remain in the bloodstream longer are widely supported because they provide faster initial resuscitation with smaller volumes of fluid and this may lead to better outcomes, particularly in terms of swelling of the tissues (oedema). However, the colloids do have some side effects in that they are associated with an increased risk of bleeding, carry a very small risk of severe allergic reactions and have a possible association with kidney injury. The controversy between these two types of fluid relates to the fact that various studies have failed to demonstrate a consistent benefit from the use of colloids and that colloids are significantly more expensive. The aim of this study is to compare resuscitation with crystalloids and colloids in patients who have suffered severe injury (trauma), either blunt (e.g. motor vehicle accidents) or penetrating (e.g. gunshot or stab wounds). The intention is to study the amount of each fluid type required in either blunt or penetrating trauma and to investigate possible differences in patient outcomes as a result of the use of one type of fluid or the other.
Who can participate?
Patients aged 18 to 60 who have suffered sufficiently severe injuries to require a minimum of 3 litres of fluid resuscitation
What does the study involve?
Participants are randomly allocated to undergo fluid resuscitation using either standard crystalloid solution (normal salt solution) or a widely used colloid solution (hydroxy ethyl starch [HES]). All participants are otherwise treated identically in a manner appropriate to the injuries received. The main measurements to be made are the volumes of fluid required in the first 24 hours, including these study fluids, and the requirement for blood and blood products. The major outcome to study is the speed of recovery of bowel function after injury. Safety markers to examine include markers of kidney damage and measurements of blood clotting. In addition, other factors to measure include the length of stay in intensive care and markers of overall organ function.
What are the possible benefits and risks of participating?
Participants benefit from being treated by experts in the field from the moment they reach the hospital. Side effects from the crystalloid might include fluid overload, with tissue swelling and possible swelling in the abdominal area that may increase the risk of complications from the injury. Side effects related to the colloid might include increased risk of bleeding, a possibility of long-term skin itching and a possibility of kidney injury related to the colloid.

Scientific title
Comparison of crystalloid-blood resuscitation with crystalloid-colloid-blood resuscitation in severe trauma patients: a randomised double-blind trial
Acronym
FIRST (Fluids In Resuscitation of Severe Trauma)
Study hypothesis
Colloid (hydroxyethyl starch HES 130/0.4 in saline) used for trauma resuscitation is superior to crystalloid (0.9% saline) solutions in terms of volumes required for resuscitation and consequent morbidity, particularly the recovery of gastrointestinal function and the incidence of complications.
