Registration Number: NCT05610969

Lead Sponsor: University of Pennsylvania

Brief Summary: This study is evaluating music vs midazolam as a means of anxiolysis for preoperative single-shot nerve block placement.

Detailed Description: Preoperative anxiety is common and can adversely affect a patient's perioperative course by elevating stress markers, promoting fluctuations in hemodynamics and negatively impacting on postoperative recovery. Preoperative anxiety is routinely treated with pharmacologic agents such as midazolam, a benzodiazepine, which has known, undesirable side effects including respiratory depression, hemodynamic perturbations, and paradoxical effects such as hostility, aggression, and psychomotor agitation. The use of sedative medications requires continuous vital sign monitoring of patients by either anesthesia or nursing personnel and there is a question of whether midazolam helps reduce pre-procedural anxiety compared with placebo. Music is a non-pharmacologic intervention that has been shown to significantly decrease preoperative anxiety. This intervention can be used as an adjunct or even replace pharmacologic agents to help with preoperative anxiety. Music is a modality that is virtually harm-free and relatively cheap in cost. Patients who are unable to tolerate pharmacologic agents to treat preoperative anxiety can greatly benefit from non-pharmacologic options such as music.

Regional anesthesia procedures such as an ultrasound guided, peripheral nerve block is a common bedside procedure done preoperatively. Patients may have some anxiety prior to the administration of this nerve block procedure and may receive sedation for it. However, it is imperative not to over sedate them as constant feedback from the patient is necessary during the procedure. Commonly, midazolam is used to reduce this anxiety, but non-pharmacologic therapies can also reduce anxiety. In our recent published study, we evaluated the use of research-selected, relaxing music, to reduce anxiety before the nerve block is administered. In this study, we used noise-canceling headphones and played research-selected music as our anxiolytic music modality and compared this with midazolam. The findings showed no difference between both groups in the change in anxiety scores from after to before the nerve block, however patients had better satisfaction in the midazolam group and increased difficulty in communication in the music group. We attributed this to not allowing patients to choose their own selection of music and the use of noise-canceling headphones.

Therefore, in this follow-up study, we aim to evaluate the use of patient-selected music via non-noise canceling headphones as a preoperative anxiolytic prior to the administration of a bedside, peripheral nerve block procedure. This study will be conducted at an ambulatory surgical center in a university setting.

Arm && Interventions

Group	Intervention	Description
Music group	Music	self-selected music
Midazolam group	Midazolam	IV midazolam (1mg to 2mg max)

Primary Outcome Measures

Name	Time	Method
Change in STAI-6 Scores From Post to Pre	1-2 minutes before conducting golden moment for nerve block placement and immediately after nerve block placement (less than 1 minute after)	Spielberger State-Trait Anxiety Inventory 6 Scale range is from 20 to 80. Higher the score, the higher the anxiety level is.

Secondary Outcome Measures

Name	Time	Method
Block Times - Time it Took to do the Block	start of doing the block to immediately after nerve block placement, less than 1 minute after	differences amongst music and midazolam group
Patient Satisfaction Scores of the Experience During Procedure	immediately after nerve block placement (less than 1 minute after)	Survey which assess satisfaction on a 10-point numeric rating scale Scale ranges from 0 to 10. A higher number indicates a higher satisfaction
Provider Satisfaction Scores of the Experience During Procedure	immediately after nerve block placement (less than 1 minute after)	survey which assess satisfaction on a 10-point numeric rating scale Scale ranges from 0 to 10. A higher number indicates a higher satisfaction
Evaluation of Difficulties in Communication From Provider to Patient and Patient to Provider	immediately after nerve block placement (less than 1 minute after)	surveyed on a 5-point Likert scale Scale ranges from 1 to 5; the higher the number, the more difficult it is to communicate.
