‘Listening to music before, after surgery relieves pain, anxiety, epilepsy seizure
PATIENTS undergoing surgery should be allowed to listen to music before, after and during their operations because it is so effective at relieving pain, researchers have suggested. A new study by Brunel University and Queen Mary University of London found that people who were allowed to relax to their favourite tunes saw their pain levels drop by two points on a scale of one to 10 while they needed less medication to feel comfortable. The study of 7,000 surgical patients also found music made them less anxious and more likely to feel satisfied by the procedure.
The research was published in The Lancet. Surprisingly, even listening to music while under general anaesthetic reduced patients’ levels of pain, although the effects were larger when patients were conscious. “Around 4.6 million in England each year and music is a non-invasive, safe, cheap intervention that should be available to everyone undergoing surgery,” said lead author Dr. Catherine Meads from Brunel University “Patients should be allowed to choose the type of music they would like to hear to maximise the benefit to their wellbeing. However, care needs to be taken that music does not interfere with the medical team’s communication.”
The study follows a recent research that found patients are being put at risk by surgeons who listen to music while operating. An analysis of 20 operations by Imperial College London found that nurses struggle to hear what equipment was being asked for while anaesthetists mistook the beat of the music for patient’s pulse rate. However, for patients themselves, it appears that music can have a major impact, and could save the health authorities millions in pain relieving drugs.
Writing in a linked Comment, Dr. Paul Glasziou from Bond University, Queensland, Australia says, “Music is a simple and cheap intervention, which reduces transient discomforts for many patients undergoing surgery. “A drug with similar effects might generate substantial marketing…The very high heterogeneity…of effects among trials in the accompanying study highlights a research opportunity—to identify how to maximise the effect.”
Meanwhile, the brains of people with epilepsy appear to react to music differently from the brains of those who do not have the disorder, a finding that could lead to new therapies to prevent seizures, according to research presented at the American Psychological Association’s 123rd Annual Convention.
“We believe that music could potentially be used as an intervention to help people with epilepsy,” said Christine Charyton, PhD, adjunct assistant professor and visiting assistant professor of neurology at The Ohio State University Wexner Medical Center, who presented the research. Approximately 80 percent of epilepsy cases are what is known as temporal lobe epilepsy, in which the seizures appear to originate in the temporal lobe of the brain.
Music is processed in the auditory cortex in this same region of the brain, which was why Charyton wanted to study the effect of music on the brains of people with epilepsy. Charyton and her colleagues compared the musical processing abilities of the brains of people with and without epilepsy using an electroencephalogram, where electrodes are attached to the scalp to detect and record brainwave patterns. They collected data from 21 patients who were in the epilepsy monitoring unit at The Ohio State University Wexner Medical Center between September 2012 and May 2014.
The researchers recorded brainwave patterns while patients listened to 10 minutes of silence, followed by either Mozart’s Sonata in D Major, Andante Movement II (K448) or John Coltrane’s rendition of My Favorite Things, a second 10-minute period of silence, the other of the two musical pieces and finally a third 10-minute period of silence.
The order of the music was randomized, meaning some participants listened to Mozart first and other participants listened to Coltrane first. The researchers found significantly higher levels of brainwave activity in participants when they were listening to music. More important, said Charyton, brainwave activity in people with epilepsy tended to synchronize more with the music, especially in the temporal lobe, than in people without epilepsy.
“We were surprised by the findings,” said Charyton. “We hypothesized that music would be processed in the brain differently than silence. We did not know if this would be the same or different for people with epilepsy.” While she does not believe music would replace current epilepsy therapy, Charyton said this research suggests music might be a novel intervention used in conjunction with traditional treatment to help prevent seizures in people with epilepsy.
