Tranexamic acid, an easily available and cheap drug, can reduce
death by bleeding, says new study. Intense bleeding following an accident is
responsible for massive loss of lives; this fact renders treatment during the
first hour critical. Arresting blood loss is of prime importance. Rapid treatment with tranexamic
acid can
save patients
with severe bleeding whether from accidents or violence.
Tranexamic acid is a common drug that can effectively reduce
the bleeding and bring down mortality by 10 per cent. It is widely available in
India. It has been in vogue for treating heavy menstrual periods. An
international study called the 'CRASH-2 trial' now supports its use in saving
lives in severe traumatic bleeding. The drug arrests bleeding by aiding blood
clot. The body has clotting mechanisms to control bleeds. However, this natural
method gets tampered following severe trauma due to accidents resulting in
heavy bleeding.
The trial found that administration of tranexamic acid within an hour of injury
significantly reduced risk of dying due to bleeding. It aids in attaining
hemostasis. The timing of drug therapy is of utmost importance since it was
found that, administration of the drug beyond 3 or 4 hours may cause no benefit or
even harm. Treatment given between one and three hours was found to cut the
risk of bleeding to death by 20% when compared with placebo. Given more than three hours
after injuryTranexamic acid could raise the risk of
death.
"Tranexamic acid should be given as early as possible to bleeding
trauma patients", the authors write. The finding was reported be The Lancet, a
leading medical journal. Early treatment within an hour of injury reduced the risk of
death due to bleeding by more than 30 per cent.
The finding can bring about revolutionary changes in treatment
protocols. An
hour can make the difference between life and death. The very fact that a drug
which is cheap and readily available can save lives is a boon to a developing
economy like ours that losses tremendous number lives to accidents. The
potential of the drug can be used in accidents, wars, or practically any event
that cause fatal bleeds.
"Tranexamic acid
should be given as early as possible to bleeding trauma patients. For trauma
patients admitted late after injury, tranexamic acid is less effective and
could be harmful", write the
authors.
