According to an international study, a bioadhesive gel or tissue: sealant synthesized from the venom of the lancehead snake (Bothrops atrox)- one of the most poisonous snakes found in South America can instantly stop severe bleeding.
“This ‘super glue’ can be applied by simply squeezing the tube and shining a visible light, such as a laser pointer, over it for a few seconds. Even a smartphone flashlight will do the job,” said Dr Kibret Mequanint, co-author of the study.
The scientists isolated the blood-clotting enzyme batroxobin, or reptilase, from the venom of lancehead snakes. The venom possesses procoagulant (promotion of clotting) activity. They developed the new bioadhesive by integrating the enzyme with a modified form of gelatin.
In comparison to clinical fibrin glue the gold standard for field and clinical surgeons the new bioadhesive had 10 times the binding strength to withstand loosening or being washed away by bleeding. The clotting time, too, was significantly shorter – fibrin glue requires 90 seconds, the new glue required only 45 seconds.
“We envision that this ‘super glue’ will be used in saving lives on the battlefield, or other accidental traumas like car crashes. The applicator easily fits in first aid kits too,” said Dr Mequanint. Along with practical on-field applications, the ‘super glue’ can be utilized for the closure of surgical wounds, potentially eliminating the need for sutures.
