Music may replace sedatives for treating pre-op anxiety

Music may replace sedatives for treating pre-op anxiety

Before undergoing an operation, most people experience some form of anxiety. Although this response is common, it is not unproblematic, and treatment often involves a sedative with a whole host of possible side effects. But new research may have found an alternative.

The biggest issue with preoperative anxietyis its ability to affect recovery, including wound healing.
Typically, people receive benzodiazepines — drugs that act as sedatives — to lower anxiety levels before receiving anesthesia.
But benzodiazepines can cause a number of side effects that may impact breathing, blood flow, and even mood. It is also necessary for a trained professional to monitor the person's response.
So, anything that simplifies the situation would be welcome. According to a new clinical trial published in Regional Anesthesia & Pain Medicine, that thing may be music.
The power of music in relation to anxiety has been the subject of previous studies. A review of 26 trials, published in 2013, concluded that music may have a "beneficial effect" on preoperative anxiety.
But no study had compared music to benzodiazepines, until now.

What makes a relaxing tune?

Experts believe that relaxing music has a very definitive sound. As Southern Medical Journal research states, a tune that involves no lyrics, no significant change in tempo or rhythm, and an estimated 60 beats per minute is the most effective in reducing anxiety.
In the new clinical trial, the researchers randomly split 157 adult participants into two groups. One group received injections of a benzodiazepine called midazolam 3 minutes before anesthesia.
The researchers gave noise canceling headphones to the other group, who listened to a preprogrammed musical track for a total of 3 minutes. The groups then received a peripheral nerve block anesthetic that numbed a specific part of the body.
The timing may seem short, but 3 minutes is how long the drug takes to reach optimum effectiveness, according to the research team.
The song choice was also intentional. The British band Marconi Union created the song in partnership with sound therapists, with the aim of lowering anxiety, along with heart rate and blood pressure.
