The spectrum includes bleeding wound sealants, super absorptive dressings and glycerated salines, all of which can save lives in the event of warfare in jungle and high altitude areas as well as in terror attacks, scientists said.
With 90 per cent of gravely wounded security personnel succumbing to injuries within a few hours, DRDO’s medical laboratory has come up with a range of ‘combat casualty drugs’ that can extend the golden hour till the trooper is shifted to hospital.
The spectrum includes bleeding wound sealants, super absorptive dressings and glycerated salines, all of which can save lives in the event of warfare in jungle and high altitude a as well as in terror attacks, scientists said.
Citing the February 14 terror attack in Pulwama where 40 CRPF soldiers were killed, they said the medicines could have brought down the death toll.
According to developers of the drugs at the Institute of Nuclear Medicine and Allied Sciences, a laboratory of the Defence Research and Development Organisation, chances of survival and minimum disability are highest when effective first aid care is given within the golden hour.
Scientists at INMAS, entrusted with research and development in a number of areas concerning the defence sector, said the main battlefield emergencies are excess bleeding, sepsis, shock, hypovolemia (decreased blood volume) and pain.
DRDO’s indigenously made medicines will be a boon for paramilitary and defence personnel during warfare, said A K Singh, director general of life sciences at the organisation.
Among the drugs developed is glycerated saline, a battlefield intravenous fluid that does not freeze till -18 degrees Celsius and is useful in handling trauma cases in high altitude areas.
According to Manju Bala Popli, senior scientist at INMAS, glycerated saline, unlike normal saline, reduces inflammation. The drug can be life saving, particularly if the traumatic edema, collection of fluid in tissues and cavities of the body, is in the brain or lungs.
“Glycerated saline has .. has life saving capacities as it gives more time to the medical personnel to shift the wounded patient to a higher care facility,” Popli said.
Additionally, antiseptics, antibiotics and curcumin can be impregnated in the dressing which acts as a slow drug release system, said a note prepared by INMAS on the medicines developed by it.
Then there is Chitosan gel, which helps in preventing blood loss by forming a film over the wound. Coupled with platelets and red blood cells aggregation, it stops the bleeding. Its antibacterial and wound health properties are of added benefit.
“Chitosan gel is suitable for sealing wounds by twin action: haemostasis by chemical action and filing action. It can be used for wounds on the limbs and also cavities such as abdomen and thorax,”
Part of the range is hypocholorous acid (HOCL), a disinfectant for troopers involved in jungle warfare.
It is helpful in treating necrotising fascitis, a rapidly progressing bacterial infection of soft tissues. Bacterial toxins cause local tissue damage and necrosis, as well as blunt immune system responses.
In such cases, pure 0.01 per cent HoCL has both broad-spectrum antimicrobial activity and can rapidly neutralise bacterial toxins.
