Reducing Preoperative Caregiver Anxiety With Virtual Reality: A Pragmatic, Randomized Controlled Study.

Pediatric patients and their caregivers often experience perioperative anxiety. Interventions reduce caregiver anxiety improve cooperation and contribute to an improved patient experience. This study seeks to evaluate the efficacy of virtual reality (VR)-assisted mindfulness on perioperative caregiver anxiety. Participants were randomized into a standard of care (SOC) group, which included snacks but no technology-based distractions, or a VR group, which included snacks and a VR-guided meditation. Caregiver anxiety was measured before and after the intervention using the Visual Analogue Scale for Anxiety (VAS-A). Secondary aims explored participants' baseline anxiety with the State-Trait Anxiety Inventory (STAI). VR group participants completed a satisfaction survey. Linear regression models of VAS-A and STAI were used to compare group differences. Satisfaction survey results were reported with descriptive statistics. 26 participants were included, with 12 randomized to the SOC group and 14 to the VR group. VAS-A scores in the VR group were lower than those in the SOC group (p = .002). The STAI found no change in participants' state of anxiety in the SOC group (p = .7108), compared to a significant reduction (p = .014) in the VR group when controlling for anxiety traits. 12 of 14 caregivers in the VR group expressed satisfaction or strong satisfaction. This study supports the implementation of VR mindfulness as a method to reduce caregiver anxiety. VR use in the pediatric healthcare setting is safe and inexpensive, and the intervention had a high degree of participant satisfaction.

Real-time reorientation and cognitive load adjustment allow for broad application of virtual reality in a pediatric hospital.

BACKGROUND: With a new generation of affordable portable virtual reality (VR), clinicians are discovering more utility for VR, while also identifying opportunities for improvement, such as the inability to reorient the horizon line during repositioning or transport, or modulate cognitive load in real time. AIM: At our institution, this lack of functionality prohibited or decreased VR usage in some clinical scenarios such as dressing changes with dynamic positioning. The purpose of this brief report is to describe the development and use of a VR application that is optimized for the healthcare setting and report historical effects of patients who utilized VR as supplement to Child Life procedures. Eligible affects per chart review included Happy, Relaxed, Anxious, Distressed, Unable to Assess. MATERIALS AND METHODS: Given the need for real-time reorientation and cognitive load modulation, we created the Space Pups™ VR application. The experience was launched as part of the Stanford Chariot Program in the summer of 2017, and its usage was tracked through the electronic medical record and a VR application dashboard. Chart review was queried from 3 January 2018 to 9 August 2021 for pediatric patients who used VR with real-time reorientation and cognitive load modulation as a supplement to their Child Life interventions. RESULTS: The Space Pups™ experience has been successfully used in a variety of settings, including perioperative care, vascular access, wound care, and ENT clinic, a total of 1696 times. Patients ranged from 6 years to 18-year old, with no reports of side effects. Significant results (P<0.001) were observed pre- and post-VR use for affect improvements in Happy, Relaxed, and Anxious, but not for Distressed. CONCLUSIONS: The ability to reorient VR experiences in real time has increased functionality where other applications have failed. RELEVANCE FOR PATIENTS: While more studies are needed to quantify the anxiolytic and pain-reducing effect of Space Pups™, our report demonstrates the feasibility of this VR experience as a non-pharmacological modality to safely increase patient cooperation in a wide variety of clinical settings.

The erector spinae plane (ESP) block: A pooled review of 242 cases.

STUDY OBJECTIVE: The erector spinae plane block (ESPB) was first described in 2016 as a regional block for thoracic neuropathic pain. Given its short history, there are a paucity of controlled clinical trials, yet an abundance of case reports. The primary aim of this review is to examine pooled clinical data from published literature to gain an understanding of ESPB characteristics. DESIGN: A PubMed search was conducted to identify all ESPB related publications. Inclusion criteria included reports of ESP single shot, continuous infusion, intermittent bolus, human and cadaveric studies. Only publications obtained in English were included. Measures included type of publication, year and country of publication, journal of publication, block technique, anatomic location, age, opioid and adjunct pain medication use, sensory and motor changes, side effects and adverse events. Qualitative statistics were used. MAIN RESULTS: The initial search yielded 201 publications. After application of inclusion and exclusion criteria, 85 publications from 21 journals were included in the pooled review which yielded 242 reported cases between 2016 and 2018. The majority of publications reported single shot techniques (80.2%), followed by intermittent boluses (12.0%) and continuous infusions (7.9%). 90.9% reported use of multimodal analgesia in addition to the ESPB and 34.7% reported sensory changes from ESPB. A reduction in opioid use was reported in 34.7% of cases. One adverse event involving a pneumothorax was reported. CONCLUSIONS: To our knowledge, this is the first review providing a pooled review of ESPB characteristics. The ESPB appears to be a safe and effective option for multiple types thoracic, abdominal, and extremity surgeries.

Two-year Outcomes from a Single Surgeon's Learning Curve Experience of Oblique Lateral Interbody Fusion without Intraoperative Neuromonitoring.

Introduction Oblique lumbar interbody fusion (OLIF) is a newer procedure that avoids the psoas and lumbosacral plexus due to its oblique trajectory into the retroperitoneal space. While early experience with OLIF is reassuring, the longer-term clinical efficacy has not been well established. The purpose of this study was to describe two-year clinical outcomes with OLIF performed by a single surgeon during the learning curve without the aid of the neuromonitoring. Materials and methods Chart review was performed for the consecutive patients who underwent OLIF by a single surgeon. Back pain severity on a visual analog scale (VAS) and Oswestry Disability Index (ODI) were collected preoperatively and postoperatively at six weeks, three months, six months, one year and two years. Results A total of 21 patients (38 levels) were included in this study. The indications for surgery were degenerative disc disease (n=10, 47.6%), spondylolisthesis (n=9, 42.9%) and spinal stenosis (n=6, 28.6%). The median operating room time was 351 minutes (interquartile range (IQR): 279-406 minutes), blood loss was 40 ml (IQR: 30-150 ml), and hospital stay was 2.0 days (IQR: 1.0-3.5 days). The complication rate was 9.5%, both venous injuries. There were no other perioperative complications. Back pain severity decreased by 70%, on average, over two years (p <0.001). A total of 17 (81%) patients reported at least a two-point decrease from the baseline. The ODI scores decreased by 55%, on average, over two years (p <0.001), with 16 (76%) patients reporting at least a 15-point decrease from the baseline. Over two years, no symptomatic pseudarthrosis, hardware failure, reoperations, or additional complications were reported. Conclusions The oblique lateral interbody fusion performed without the intraoperative neuromonitoring was safe and clinically efficacious for up to two years. The complication rate in this cohort is similar to other published OLIF series and appears acceptable when compared to the lateral lumbar interbody fusion (LLIF) and the anterior lumbar interbody fusion (ALIF). No motor or sensory deficits were observed in this study, supporting the premise that the neuromonitoring is unnecessary in OLIF.
