Washington: The role of the stethoscope, the ubiquitous tool of the medical profession for over 200 years, is at the center of debate in the US with a leading Indian-origin cardiologist declaring “the stethoscope is dead”.
In recent years, the sounds it transmits from the heart, lungs, blood vessels and bowels have been digitised, amplified, filtered and recorded.
Algorithms already exist that can analyze the clues picked up by a stethoscope and offer a possible diagnosis.
But whether all this represents the rebirth of diagnostic possibility or the death rattle of an obsolete device is a subject of spirited discussion in cardiology, The Washington Post reported.
he widespread use of echocardiograms and the development of pocket-size ultrasound devices are raising questions about why doctors and others continue to sling earphones and rubber tubing around their necks.
“The stethoscope is dead,” said Jagat Narula, a cardiologist and associate dean for global health at the Icahn School of Medicine at Mount Sinai Hospital in New York.
“The time for the stethoscope is gone,” Narula said.
Starting in 2012, Mount Sinai began giving its students hand-held ultrasound devices that are little bigger than a cellphone but can generate real-time images of the heart right at the bedside. Several other schools will join the experiment in the coming months, the report said.
Stethoscopes retain their value for listening to lungs and bowels for clues of disease, experts say.
But for the cardiovascular system, “auscultation is superfluous. We are wasting []students’] time,” Narula said. “Why should I not have an echocardiogram in my hand if it’s as small as the stethoscope?”
Not so, counters W. Reid Thompson, an associate professor of pediatrics at Johns Hopkins University School of Medicine.
“We are not at the place, and probably won’t be for a very long time,” where listening to the body’s sounds is replaced by imaging. “It is valuable,” he said.
One thing on which both sides agree, however, is that doctors are not very good at using stethoscopes — and have not been for a long while, the report said.
