“[R]esearchers are now on a quest to find objective biological indicators of pain that will enable doctors to quantify it as they do heart rate and blood pressure,” according to the Washington Post which recently described the Nociometer.
Julia Finkel, a pediatric anesthesiologist at Children’s National Hospital in Washington, is developing the Nociometer, which would determine the type and intensity of pain and the impact of analgesics.
The newspaper reported that, “[t]he Nociometer stimulates the patient’s three main sensory and pain nerve fibers — found in skin, muscles, joints and some organs — without actually causing pain. Instead, the device sends a tiny electrical current through a probe, usually attached to the patient’s finger or toe. The three fibers each transmit a different kind of sensation: temperature and slow-burning pain; sharp, localized pain; and touch and pressure.”
The handheld instrument by AlgometRx, Inc., would allow doctors to analyze pupil dilation in response to the electrical current.
