Effectiveness of virtual reality as a distraction on anxiety and pain during impacted mandibular third molar surgery under local Anesthesia

Virtual Reality Glasses Reduce Patients' Anxiety During Emergency Surgical Procedures Under Local Anesthesia: A Randomized Controlled Clinical Study

INTRODUCTION

In the emergency department patients experience high levels of anxiety during suturing because they are conscious, feel pain, are suffering owing to trauma, and believe they will experience pain during the suturing. This study aimed to evaluate the effect of virtual reality glasses on patients' anxiety during the suturing under local anesthesia in the emergency department.

METHODS

This prospective, parallel 2-arm, randomized controlled clinical study involved 138 patients admitted to the emergency department of a public hospital in Mersin, Turkey. The virtual reality glasses group (n = 69) watched videos through virtual reality glasses during the suturing, and the control group (n = 69) received routine practice. Patients' anxiety level was assessed using the State Anxiety Inventory and measured via physiological responses to anxiety, such as changes in systolic blood pressure, diastolic blood pressure, heart rate, respiratory rate, and peripheral oxygen saturation, before and after suturing.

RESULTS

Watching videos through virtual reality glasses resulted in significantly lower State Anxiety Inventory scores and different systolic blood pressure, diastolic blood pressure, respiratory rate, and peripheral oxygen saturation, but not heart rate, in the virtual reality glasses group than the control group after suturing (P < 0.05).

DISCUSSION

The study results suggest that virtual reality glasses attenuate psychological and physiological responses to anxiety in patients during emergency suturing under local anesthesia, positively affecting all examined physiological parameters except heart rate. Therefore, nurses can use virtual reality glasses to reduce anxiety in patients undergoing suturing in the emergency department.

The Effect of Immersive Virtual Reality on Dental Anxiety and Intraoperative Pain in Adults Undergoing Local Anesthesia: A Randomized Clinical Trial

AIMS

This study assessed the effect of immersive virtual reality (IVR) on anxiety and intraoperative pain in adult patients undergoing dental extractions with local anesthesia.

METHODS

In a single-blind, randomized clinical trial from September 2022 to December 2023 at a private dental clinic, 190 patients with dental anxiety were randomly assigned to either an IVR or a control group. Primary outcomes-dental anxiety and perioperative pain-were measured using the State-Trait Anxiety Inventory (STAI), Modified Dental Anxiety Scale (MDAS), and Visual Analogue Scale (VAS) before and after the procedure. Secondary outcomes included heart rate (HR), diastolic blood pressure (DBP), and systolic blood pressure (SBP), recorded at various stages.

RESULTS

The IVR group showed significant reductions in total anxiety, state anxiety, and MDAS scores compared to the control group (p < 0.001). Pain intensity was also lower in the IVR group (p = 0.03). Additionally, heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) were consistently lower in the IVR group across different stages. Post anesthesia, the IVR group showed notably lower mean SBP and DBP values (p < 0.001). After surgery, the IVR group also showed lower HR (p = 0.01), SBP (p < 0.001), and DBP (p < 0.001) compared to the control group.

CONCLUSIONS

IVR significantly reduced STAI, STAI-S, and MDAS scores and decreased intraoperative pain compared to the control group.

Does virtual reality reduce anxiety and pain in patients undergoing third molar surgery? A systematic review and meta-analysis

This study aimed to systematically review the literature to evaluate the effectiveness of virtual reality in reducing anxiety and pain in patients undergoing third molar surgeries. Clinical trials evaluating patients who used virtual reality (VR) compared with no VR in the management of pain or anxiety after third molar extractions were included. A literature search was conducted in five electronic databases to identify relevant articles: Medline (PubMed interface), Web of Science, Virtual Health Library, Embase, and Scopus. There were no restrictions on the time or language of publication. The risk of bias was assessed using the Cochrane Risk of Bias Tool for Randomised Trials (RoB 2.0). A total of six studies were included in the qualitative analysis and three in the quantitative analysis. The results of the meta-analyses on anxiety revealed that patients in the intervention group before VR already showed less anxiety compared to those in the control group (-0.28 [-0.44 to -0.13, 95%CI] I²=24.51%. In the post-intervention evaluation, the group that received VR remained with a lower level of anxiety and a slight reduction compared to the pre-intervention. (-0.34 [-0.49 to -0.19, 95%CI] I²=36.61%. Virtual reality can be a clinical resource in dental care because it seems to cause a small reduction in anxiety, and with still uncertain results in the reduction of postoperative pain in extractions of third molars.

Different Uses of Conscious Sedation for Managing Dental Anxiety During Third-Molar Extraction: Clinical Evidence and State of the Art

Dental anxiety, linked to avoiding dental treatment and heightened medical and surgical risks, prompted this systematic review. The objective is to synthesize existing evidence on conscious sedation techniques employed for managing dental anxiety in patients scheduled for third molar extraction surgery, aiming to identify optimal approaches and address knowledge gaps. This systematic review followed the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" checklist and the population, investigation, comparation, outcome framework. The protocol still needs to be registered. A thorough search was conducted, incorporating MEDLINE/PubMed, EMBASE, SCOPUS, clinicaltrials.gov, and the Cochrane Database of Systematic Reviews until February 2024. Only randomized controlled trials were considered, following "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" guidelines. The risk of bias was evaluated following the Cochrane Handbook for Systematic Reviews of Interventions. Eighteen randomized controlled trials involving 2081 patients were included. Certain factors limited the feasibility of a meaningful meta-analysis, leading to a narrative synthesis. Conscious sedation with virtual reality showed an association with improved dental anxiety in 4 studies. One study reported reduced cortisol levels with midazolam compared with a placebo, whereas another noted significant variations in perioperative renin levels with remifentanil versus placebo. This review reveals inconclusive and conflicting findings regarding the role of conscious sedation in managing dental anxiety during third molar extraction surgery. Persistent uncertainties arise due to a need for consistent, standardized outcome measures. Addressing these limitations in study design is crucial for future research.

Investigation of the effect of virtual reality distraction in patients undergoing mandibular periodontal surgery: A randomized controlled study

OBJECTIVE

This clinical study aimed to evaluate the effect of virtual reality (VR) technology on anxiety and pain levels in patients undergoing gingivectomy and gingivoplasty procedures.

MATERIALS AND METHODS

The patients were randomized into test (surgery with VR glasses) and control (surgery without VR glasses) groups. Before the surgery, the anxiety level was measured using the modified dental anxiety scale (MDAS), and anticipated pain (AP) was measured by a visual analog scale (VAS). Immediately after the surgery, the pain and discomfort associated with the surgery (VASP), procedure time (T), and time perception (TP) were evaluated. The patients in the test group were requested to assess the immersion (VASI), satisfaction (VASS), perception of reduced anxiety (VASA), and perceived control (VASC). One week after surgery, MDAS was applied to all patients.

RESULTS

This trial was conducted with 41 female and 17 male subjects with a mean age of 29.69 ± 12.32. There were no significant differences between the groups in terms of age, sex, preoperative MDAS, or AP. After surgery, MDAS, VASP, T, and TP failed to differ significantly between the groups. The subject age was positively correlated with VASI, VASS, VASA, and VASC (r = 0.60, p = 0.00; r = 0.44, p = 0.02; r = 0.46, p = 0.02; r = 0.50, p = 0.01, respectively) and negatively correlated with VASP (r = 0.47, p = 0.04).

CONCLUSIONS

VR application did not affect anxiety and pain levels in patients undergoing periodontal surgery. More studies are needed to evaluate VR distraction in periodontal surgeries with diverse age samples and video options.

CLINICAL SIGNIFICANCE

VR does not affect anxiety and pain levels during gingivectomy and gingivoplasty surgeries in the young adult population. It should be evaluated in older age groups. Trial registration ClinicalTrials.gov Identifier: NCT06092177.

Effectiveness of virtual reality in relieving anxiety and controlling hemodynamics during oral surgery under local anesthesia: A prospective randomized comparative study

It was the aim of the study to evaluate the contribution of a relaxing immersive experience with virtual reality (VR) goggles in reducing patient anxiety related to wisdom tooth extraction under local anesthesia. A prospective randomized comparative study in consecutive patients scheduled for bilateral wisdom tooth extraction under local anesthesia was carried out between March and December 2022. Both sides were operated upon in the same surgery, but on one side VR goggles were applied (VR), while on the other they were not (noVR). Anxiety was evaluated both subjectively (State-Trait Anxiety Inventory [STAI] and visual analogue scale [VAS]) and objectively (measuring heart rate, blood pressure [BP] and blood oxygen saturation) before (T1) and after each surgical step (T2VR and T2noVR). The study sample consisted of 27 patients: 9 men and 18 women, with an average age of 25.8 ± 6.5 years (range: 18-43). Anxiety as assessed by the STAI and VAS decreased from T1 to T2 (p < 0.001 and p < 0.001, respectively), although to a similar degree regardless of whether VR was used or not. Heart rate showed significant differences influenced by RV exposure (p = 0.013): it increased +2.5 ± 8.8 bpm in the control group and decreased -2.22 ± 7.55 bpm with VR (p = 0.013). Both minimum and maximum BP after surgery were significantly higher in the noVR group (p = 0.002 and p = 0.040, respectively). Regarding minimum BP, VR proved more effective among male patients (p = 0.057) and on starting the procedure using VR (p = 0.055). The results provided evidence of meaningful control of the hemodynamic variables, but less predictable performance in the subjective evaluation of anxiety.

Virtual reality in managing dental pain and anxiety: a comprehensive review

Objectives

This study aimed to identify, analyze, and summarize the clinical efficacy of virtual reality (VR) distraction therapy for oral treatment in different hospital settings in contrast to medical interventions that induce anxiety and pain. Furthermore, this review aimed to determine the implications for research and clinical practice of VR distraction therapy.

Data

This review investigated the clinical efficacy of VR in the oral treatment of procedural pain or anxiety. Quality assessment of the included studies was conducted. A narrative synthesis of the collected data was performed.

Sources

Literature studies from six electronic databases were searched for a comprehensive review, namely, the Cochrane Oral Health's Trials Register, Cochrane Central Register of Controlled Trials (Central), MEDLINE (PubMed), EMBASE, Scopus, and Web of Science.

Study selection

One thousand five hundred twenty-two patients aged between 0 and 60 years who used VR during dental treatment were included in this review. Among these studies, 8 and 14 studies comprised adult and pediatric patients.

Conclusion

Overall, the reviewed studies underscore the efficacy of VR to mitigate pain and anxiety in the context of dental treatment. VR is an innovative pain and anxiety management approach that facilitates dental treatment patients to immerse themselves in a virtual world while using distractions to reduce pain and anxiety.

Clinical significance

VR is an effective and novel non-pharmacological method of behavioral management that contributes to improving medication safety for dental patients. VR as a distractive approach can reduce the fear associated with medical interventions and prevent severe pain sensitivity, anxiety, and medical avoidance among adults and children.

The Use of Virtual Reality to Reduce Pain and Anxiety in Surgical Procedures of the Oral Cavity: A Scoping Review

PURPOSE

Virtual reality (VR) is considered a nonpharmacological intervention to manage pain and anxiety for different procedures. We aimed to review the literature about the role of VR in reducing pain and anxiety in surgical procedures performed in the oral cavity.

METHODS

A literature review was conducted using Medline and Embase with no restrictions on language or publication date. Our inclusion criteria were articles related to the use of VR to manage perioperative pain and anxiety on procedures in the oral cavity.

RESULTS

Twenty-seven articles met the inclusion criteria. The number of publications increased significantly from 2 studies between 2000-2010 to 25 between 2011 and 2021. Of the 27 included studies, 22 (81.4%) studied patients undergoing dental procedures, and 5 (18.5%) in oral and maxillofacial surgery (OMS). There was heterogeneity in the VR software used in the different studies. Thirteen studies (41.9%) evaluated self or observational assessments of pain and anxiety. Pain alone was evaluated in 9 studies (29%) and anxiety alone in 8 studies (25.8%). Also, 6 studies (19.3%) evaluated physiological parameters such as heart rate and respiratory rate as objective measures of pain and anxiety. In oral surgery studies, VR was effective at reducing acute pain, fear, and anxiety levels.

CONCLUSIONS

There is a paucity of research in OMS compared to dentistry. Given that this specialty involves highly stimulating and anxiety-provoking procedures, OMS could benefit from VR intervention for improved patient care.

Virtual reality distraction, a novel tool for pain alleviation during dressing change following surgical drainage of perianal abscess at Day Treatment Centre

Background

The pain induced by postoperative dressing changes adversely influence recovery and quality of life. In this study, we try to evaluate the pain alleviation effect of virtual reality (VR) distraction during postoperative dressing changes of patients who received surgical drainage of perianal abscess.

Methods

This was a prospective, randomized clinical trial. A total of 172 patients with perianal abscess were randomly assigned into control (only analgesics) and VR groups (VR distraction + analgesics). The pain and physiological measurements of all patients were collected before, during, and after the first dressing change following surgery. The difference in pain intensity and physiological parameters measurement between control and VR group was analyzed.

Results

The baseline characteristics of VR and control group were comparable (all P > 0.05). There was no significant difference in mean pain scores prior to and after dressing change between groups (both P > 0.05). Mean pain scores of 5, 10, 15, and 20 min measuring points during the first dressing change were significantly lower in the VR group compared with the control group (all P < 0.05). Pulse rates and oxygen saturation were not significantly different between groups.

Conclusion

VR can be used as an effective adjuvant pain distraction approach for postoperative dressing change.

Food allergy, mechanisms, diagnosis and treatment: Innovation through a multi-targeted approach

The incidence of food allergy (FA) has continued to rise over the last several decades, posing significant burdens on health and quality of life. Significant strides into the advancement of FA diagnosis, prevention, and treatment have been made in recent years. In an effort to lower reliance on resource-intensive food challenges, the field has continued work toward the development of highly sensitive and specific assays capable of high-throughput analysis to assist in the diagnosis FA. In looking toward early infancy as a critical period in the development of allergy or acquisition of tolerance, evidence has increasingly suggested that early intervention via the early introduction of food allergens and maintenance of skin barrier function may decrease the risk of FA. As such, large-scale investigations are underway evaluating infant feeding and the impact of emollient and steroid use in infants with dry skin for the prevention of allergy. On the other end of the spectrum, the past few years have been witness to an explosive increase in clinical trials of novel and innovative therapeutic strategies aimed at the treatment of FA in those whom the disease has already manifested. A milestone in the field, 2020 marked the approval of the first drug, oral peanut allergen, for the indication of peanut allergy. With a foundation of promising data supporting the safety and efficacy of single- and multi-allergen oral immunotherapy, current efforts have turned toward the use of probiotics, biologic agents, and modified allergens to optimize and improve upon existing paradigms. Through these advancements, the field hopes to gain footing in the ongoing battle against FA.

Non-Pharmacological Interventions for Reducing Fear and Anxiety in Patients Undergoing Third Molar Extraction under Local Anesthesia: Systematic Review and Meta-Analysis

This report investigated the effectiveness of non-pharmacological interventions for reducing dental fear and anxiety in patients undergoing third molar extraction under local anesthesia. In November 2020, multiple electronic databases (Cochrane, EMBASE, MEDLINE, PsycInfo, PsycArticles, PubMed, and Web of Science) were searched for articles published in English. Inclusion criteria were randomized-controlled trials reporting the effectiveness of any non-pharmacological interventions in reducing fear or anxiety levels in patients with third molar extraction. A total of 3015 studies by electronic search and 2 studies by hand search were identified. After screening, 21 studies were eligible for systematic review. Seven studies were included in the meta-analysis. Study selection, data extraction, and quality assessment of the included studies were performed by two independent investigators. The anxiety levels after intervention in each study were pooled and meta-analyzed by the random-effect model. A significant reduction in anxiety level was observed in non-pharmacological intervention groups (SMD = -0.32; 95% CI -0.57 to -0.07; p = 0.01). Subgroup analyses showed that a significant anxiety reduction by non-pharmacological interventions could be demonstrated by pooled data from studies using psychometric assessments, but not from studies using physiological assessments. Non-pharmacological interventions appear to reduce fear and anxiety levels in patients undergoing third molar extraction under local anesthesia.

Effect of Virtual Reality on Pain Management and Opioid Use Among Hospitalized Patients After Head and Neck Surgery: A Randomized Clinical Trial

Importance

Optimal postoperative pain management is challenging. Virtual reality (VR) provides immersive, 3-dimensional experiences that may improve pain control and reduce reliance on pharmacologic pain management.

Objective

To evaluate use of VR on postoperative pain management after head and neck surgery.

Design, Setting, and Participants

This prospective, pilot randomized clinical trial was conducted at Oregon Health & Science University from July 2020 to October 2021 and included patients hospitalized after major head and neck surgery.

Interventions

Similar 15-minute interactive gaming experiences (Angry Birds) using an Oculus Quest VR headset (VR intervention) or a handheld smartphone device (control).

Main Outcomes and Measures

The primary outcome was postintervention pain reduction. Pain scores were obtained preintervention, immediately after intervention, and then hourly for 4 hours. Secondary outcomes included changes in opioid use, measured as milligram morphine equivalents (MMEs), and patient experiences with their intervention using 5-point Likert scales.

Results

Of the 30 patients randomized for inclusion, the final population included 14 patients in the VR cohort and 15 patients in the control cohort; the majority of patients were male (26 of 29 [90%]), and the mean (SD) age was 58.3 (13.8) years. After outlier removal, there were clinically meaningful reductions in postintervention pain among patients in the VR group immediately after intervention (mean difference, -1.42; 95% CI, -2.15 to -0.70; d = 1.50), at 1 hour (mean difference, -0.86; 95% CI, -1.90 to 0.14; d = 0.67), 2 hours (mean difference, -1.07; 95% CI, -2.30 to 0.14; d = 0.69), and 3 hours (mean difference, -1.36; 95% CI, -2.80 to 0.13; d = 0.71) compared with patients in the control group. Patients in the VR group also demonstrated reductions in 4-hour postintervention opioid use compared with 4-hour preintervention opioid use (mean difference, -9.10 MME; 95% CI, -15.00 to -1.27 MME; d = 0.90) and 8-hour postintervention opioid use compared with 8-hour preintervention opioid use (mean difference, -14.00 MME; 95% CI, -25.60 to -2.40 MME; d = 0.94). There were no meaningful differences in subjective patient experiences with their respective interventions.

Conclusions and Relevance

In this randomized clinical trial, VR reduced pain scores and opioid use compared with a control intervention. Virtual reality may be a useful adjunct for postoperative pain management after head and neck surgery.
