WESTPORT, CT (Reuters Health) – A new method of analyzing infant cries might be a feasible way to assess infant pain–and perhaps someday assess pain in noncommunicative older children and adults. It was described in a poster presented Monday at the annual meeting of the American College of Clinical Pharmacology in Tampa, Florida.
"There is a distinct pattern to cries and other sounds that an infant emits during a painful stimulus that can be correlated with heart rate and other psychological variables," Dr. Victoria Tutag-Lehr from Wayne State University, in Detroit, told Reuters Health.
Dr. Tutag-Lehr and colleagues recorded the cries of 12 male infants during circumcision, using advanced recording equipment, and later used a musical notation program to display the data. They found that characteristics such as the duration of sound, the suddenness of the onset of sound, and rhythm varied as the painfulness of the procedure varied.
Such information could be useful in monitoring the effect of an analgesic and monitoring the response of infants to other procedures, Dr. Tutag-Lehr said. "We are looking to apply this method to other situations when patients are nonverbal–autism and stroke for example," she added. "Another application would be looking at the level of sedation in a patient in the intensive care unit."
"We predict that one day there will be an additional monitoring parameter on the monitors–cry–along with heart rate, blood pressure, and respiratory rate," she concluded.
