Medical glue ‘can fix broken heart’

heart-glue

A medical superglue has been developed that has the potential to patch heart defects on the operating table or stop bleeding on the battlefield.

The new adhesive may eventually replace stitches and staples in heart, gut and blood vessel surgery, says a US team.

Tests on pigs show it can seal cardiac defects in seconds and withstand the forces inside the heart.

The glue, inspired by the sticking abilities of slugs, could be available for human use in two years.

Skin glue is a special type of medical adhesive used to join the edges of a wound together, while the wound starts to heal.

Medics may use skin glue to close wounds, instead of other methods such as stitches or staples.

Portable devices save lives in sudden cardiac arrests

2013 June 25 tech2 Portable devices save lives in sudden cardiac arrests Nimit Ahuja, a 35-year old software professional, was shopping at a mall when he suddenly collapsed. He was rushed to a hospital where he was pronounced dead. He had suffered from what doctors call a sudden cardiac arrest.

Cardiologists say young lives like these can be saved if there are facilities like Automated External Defibrillators (AED) available at public places in India. An AED is a portable device that can automatically diagnose a sudden cardiac arrest and help save life with the press of a button. It sends an electric shock to the heart to restore its normal rhythm and bring a person back from the verge of death.

“An AED, if used during a cardiac arrest within the first 4-6 minutes, can save more than 95 percent of lives,” Bipin Kumar Dubey, director, department of cardiology in the Rockland group of hospitals, told IANS.

“There should be at least one AED available at all public spaces like shopping malls and airports. The government should make it mandatory for builders to set up at least one AED in all public buildings,” he said.

Doctors said Sudden Cardiac Arrest (SCA) is a leading cause of death and account for greater than 50 percent of cardiovascular deaths in India. More than 660,000 deaths occur every year in India alone as a result of SCA.

The SCA is a condition in which the heart suddenly and unexpectedly stops beating. If this happens, blood stops flowing to the brain and other vital organs.

Experts said people who have heart disease are at a higher risk for SCA. SCA can however happen in people who appear healthy and have no known heart disease or other risk factors like hypertension.

Ram E. Rajagopalan in the department of critical care medicine in Sundaram Medical Foundation of Chennai said if an AED is used on a patient suffering with a sudden cardiac arrest his chances of survival will grow by more than 60 percent.

“We definitely need the common man to be aware of what an AED is, as anyone anywhere with access to an AED can save a life,” Rajagopalan told IANS.

Lamenting that very few people know how to respond to emergency situations like SCAs in India, Anil Bansal, chief cardiologist at Columbia Asia Hospital in Gurgaon, said people have to be trained to use an AED.

“The need of the hour is to make AED devices available at all public spaces and to train people on how to use them,” he added.

A recent study in medical journal Lancet said that by 2010, 60 percent of the world’s heart patients would be in India.

As per World Health Organization (WHO) statistics, mortality due to cardiac causes has overtaken mortality due to all cancers put together across the world.
