Anesthesiologists are putting ultrasound in hospitals for the first time, and the machines are finding a variety of uses, including diagnosing the underlying causes of pain.
But some hospitals are concerned about the potential for misuse and the technology may be less reliable than the devices implanted in the nose, mouth and throat.
The American Academy of Orthopaedic Surgeons issued a statement in May urging doctors to stay away from using ultrasound in the hands.
The AMA said the FDA should consider requiring manufacturers to test and certify devices for accuracy before using them in a hospital setting.
Ultrasurgery is a type of surgery, but the use of ultrasound in surgeries has been a relatively new technology.
In 2016, the American Society of Anesthesiology, which represents the world’s most prestigious medical society, said there were currently no federal rules in place requiring the use, in hospitals or otherwise, of ultrasound devices for the purpose of anesthetizing patients or improving surgical outcomes.
The ASA has a long history of backing the use and approval of ultrasound for surgical procedures.
But the AMA said in a statement on Wednesday that it was not recommending the FDA restrict its approval of the devices.
The agency has not yet issued a final rule on the devices, but said it was considering adding an opt-out provision to its existing regulations.
A spokeswoman for the FDA said the agency had no comment.
