Facteur VIIa: Intérêt pas prouvé !

Use of recombinant factor VIIA for control of combat-related haemorrhage.

Woodruff SI et all. Emerg Med J 2010;27:2 121-124

Ce travail  met en exergue que le recours au FVIIa n'a pas d'intérêt prouvé en cas de prise en charge de traumatismes pénétrants. Ceci est d'autant plus vrai qu'il est fait alors qu'une coagulopathie sévère est installée (The utility of recombinant factor VIIa as a last resort in trauma. Mamtani R. et all. World Journal of Emergency Surgery 2012, 7(Suppl 1):S7)

----------------------------------------------

Background 

Recombinant activated human coagulation factor VII (rFVIIa), an intravascular strategy to promote clotting, is being used as an adjunct to surgical control of bleeding in combat trauma patients.

Objective 

To describe the initial experiences with rFVIIa administered to combat casualties at US Navy-Marine Corps medical treatment facilities in Iraq, and to comparesurvival outcomes of those treated with rFVIIa to controls not receiving rFVIIa.

Methods

Medical encounter data from the US Navy-Marine Corps Combat Trauma Registry were retrospectively reviewed to identify all battle-injured patients documented as having received rFVIIa during the period May 2004 to January 2006 of Operation Iraqi Freedom. Available clinical and injury related data are presented to characterise the patients. To assess effects of rFVIIa on survival outcomes, rFVIIa cases were matched to controls on injury severity and age.

Results 

22 battle-injured patients from the Combat Trauma Registry received rFVIIa. Primarily young US Marines, these patients typically had penetrating injuries from improvised explosive devices and gunshot wounds. Injuries were often abdominal. The average dose used was similar to that reported in another study of civilian trauma patients, although dosing varies widely in the existing experimental and anecdotal literature. Over two-thirds (68%) of the rFVIIa patients surviveddan identical outcome seen for a matched control group of 22 patients.

Conclusions 

Survival of seriously injured combat casualties was good, although identical to that of a control group. Methodological limitations of this retrospective study preclude making firm conclusions about the effectiveness of rFVIIa. Future controlled studies are needed for safety and efficacy testing of rFVIIa in combat trauma patients.
