A new nasal spray may give snake bite victims at shot at survival.
As many as 125,000 people die each year from from venomous snake bites. The challenge? Getting to a hospital in time to get a dose of anti-venom. Most victims die on the way.
Drugs used to treat snakebites aren’t easy to use in the wild. So researchers developed a nasal spray to deliver anti-venom drugs (anticholinesterase agents such as neostigmine.) They have been used for decades on snake bite victims, but the challenge is they have to be administered with a needle.
In April 2013, researchers from the California Academy of Sciences and the University of California, San Francisco tested delivery of the life saving medicine via nasal spray. In India a doctor has since successfully used the spray to reverse facial paralysis in a patient who had been bitten by a krait, a common venomous snake found in Indian and south Asian jungles. One bite from a krait has enough venom to kill two grown men.
The patient recovered from the facial paralysis in half an hour, and was back on their feet within two weeks.0Need at least 3 ratings
