Mindfulness Intervention on Minimally Invasive Vascular Surgery

June 15, 2026 updated by: Wan Kuang, Tongji Hospital

Effect of Mindfulness Intervention Based on Virtual Reality Technology on Anxiety and Pain in Minimally Invasive Vascular Surgery Under Local Anesthesia: a Single-center, Prospective, Randomized Controlled Clinical Study

Background: Patients undergoing minimally invasive vascular surgery under local anesthesia often experience significant anxiety and pain, which may compromise surgical outcomes. Virtual reality (VR)-based mindfulness interventions may offer a novel approach to enhance the perioperative experience. Methods: This single-center, prospective randomized controlled trial will enroll 160 patients, randomly assigned in a 1:1 ratio to either the intervention group (VR mindfulness intervention) or the control group (standard care). Primary outcome: State trait anxiety scale (STAI-State) measures anxiety. Secondary outcomes: Numeric Rating Scale (NRS) for pain, vital signs, sleep quality, fatigue levels, satisfaction. Expected Results: VR mindfulness intervention is anticipated to significantly reduce anxiety and pain levels while improving sleep quality, fatigue levels, and patient satisfaction. Conclusion: As a safe, cost-effective, and immersive non-pharmacological intervention, VR mindfulness therapy holds promise for enhancing perioperative care quality.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study randomly assigned 160 patients whose groups had not yet been determined to two groups (intervention and control) in a 1:1 ratio. The block size was set to 4 based on the number of study groups. Randomization into 40 blocks was performed using SAS 9.4 software. Group allocation was concealed using the envelope method. A trained nurse sequentially opened envelopes according to patient enrollment order and assigned patients to the control or intervention group based on the allocation plan within each envelope.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Mindfulness intervention based on virtual reality technology
On the day of surgery, the first intervention took place in the preoperative waiting area. A mindfulness-trained operating room nurse guided the patient in wearing Huawei VR glasses and selecting pre-recorded mindfulness audio track A. The second intervention occurred in the operating room at the start of surgery. The patient again wore Huawei VR glasses and selected pre-recorded mindfulness audio track B.
Behavioral: Mindfulness intervention based on virtual reality technology
On the day of surgery, the operating room staff brought patients to the preoperative waiting area in advance. Patients in the intervention group were assigned to a dedicated room within the preoperative waiting area. They were invited to sit in comfortable chairs and observe their surroundings. Operating room nurses trained in mindfulness assisted patients in putting on Huawei VR Glasses. They selected the pre-recorded Mindfulness Theory Course 1 + Guided Mindfulness Audio A for the first intervention. Subsequently, a second intervention was conducted when patients entered the operating room and surgery commenced. Operating room nurses assisted patients in wearing the Huawei VR Glass and selected the pre-recorded mindfulness theory course 2 + mindfulness guidance audio B.
No Intervention: Routine Psychological Care
The control group patients received routine psychological care under identical medical conditions, including preoperative visits (providing information about the surgical procedure, expected outcomes, and other surgery-related details) and psychological support (comfort and encouragement).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description

State-Trait Anxiety Inventory（STAI-State）
Time Frame: Upon arrival at waiting room (baseline), immediately prior to departure from waiting room (preoperative), and immediately upon surgical closure (prior to operating room departure)
Total scores ranging from 20 to 80, where higher scores indicate greater anxiety.
Upon arrival at waiting room (baseline), immediately prior to departure from waiting room (preoperative), and immediately upon surgical closure (prior to operating room departure)

Secondary Outcome Measures

Secondary Outcome Measures
