However, music is limited in its ability to produce anxiolysis, being dependent on the nature and rhythm of the music, e.g. The value of music in decreasing anxiety before surgery has been demonstrated in a number of recent studies. Traditional pharmacological anxiolysis fails to meet these aims and, as part of a more rational approach, pre-operative psychological preparation has become recognised as a potential route towards achieving these contrasting goals. ĭay case surgery combines the need for a ‘street ready’ patient soon after surgery with the goal of low pre-operative anxiety. Patients with a low predisposition to anxiety who become apprehensive whilst awaiting surgery may develop gastric stasis. Evidence of heightened pre-operative anxiety is not always specifically sought by anaesthetists despite demonstrations that it increases intra-operative anaesthetic requirements and postoperative pain. Worries about loss of control, being in an unfamiliar environment and the perceived risk of morbidity and mortality all contribute to this unpleasant phenomenon. Binaural beat audio has the potential to decrease acute pre-operative anxiety significantly.Ī high level of pre-operative anxiety is commonplace in adult patients. No Intervention Group) and 3.8% in the No Intervention Group. No Intervention Group), 11.1% in the Audio Group (p = 0.15 vs. Mean decreases in anxiety scores were 26.3% in the Binaural Group (p = 0.001 vs.
We measured anxiety with the State-Trait Anxiety Inventory questionnaire and compared binaural beat audio (Binaural Group) with an identical soundtrack but without these added tones (Audio Group) and with a third group who received no specific intervention (No Intervention Group). Recently, it has been demonstrated that music can be used successfully to relieve patient anxiety before operations, and that audio embedded with tones that create binaural beats within the brain of the listener decreases subjective levels of anxiety in patients with chronic anxiety states.
Ambulatory surgery challenges our pre-operative goal of an anxiety-free patient by requiring people to be ‘street ready’ within a brief period of time after surgery. Pre-operative anxiety is common and often significant.
