Investigating the effect of multi-coated hydrogel layer on characteristics of electrospun PCL membrane coated with gelatin/silver nanoparticles for wound dressing application

In this study, the effect of coated hydrogel layer on characteristics of the whole gelatin/silver nanoparticles multi-coated polycaprolactone membrane (PCLGelAg) was investigated through systematic and typical wound dressing characterizations to select the optimal number of layers for practical applications. Scanning electron microscopy, free swell absorptive capacity and tensile test in both wet and dry conditions were conducted to characterize all fabricated membranes of six coating times. In vitro cytotoxicity and agar diffusion evaluation were also carried out to assess the biocompatibility and antibacterial activity of the membranes. The findings illustrated that as the coated layers increase, the absorptive capacity, and degradation rate were higher, the membranes were stiffer in dry state while the tensile strength in wet state, elongation, and cell viability were significantly decreased. PCLGelAg3 was chosen to be the best fit for wound healing since it maintained quite sufficient maximum buffer uptake, elasticity, cell viability along with inducing abnormalities in bacterial morphology and preventing biofilm formation.

Efficacy of Smartphone Active and Passive Virtual Reality Distraction vs Standard Care on Burn Pain Among Pediatric Patients: A Randomized Clinical Trial

IMPORTANCE

It is unknown whether smartphone-based virtual reality (VR) games are effective in reducing pain among pediatric patients in real-world burn clinics.

OBJECTIVE

To evaluate the efficacy of a smartphone VR game on dressing pain among pediatric patients with burns.

DESIGN, SETTING, AND PARTICIPANTS

This randomized clinical trial included children aged 6 to 17 years who seen in the outpatient clinic of a large American Burn Association-verified pediatric burn center and level I pediatric trauma center between December 30, 2016, and January 23, 2019. Speaking English as their primary language was an inclusion criterion. Intention-to-treat data analyses were conducted from December 2019 to March 2020.

INTERVENTIONS

Active VR participants played a VR game; passive VR participants were immersed in the same VR environment without interactions. Both groups were compared with a standard care group. One researcher administered VR and observed pain while another researcher administered a posttrial survey that measured the child's perceived pain and VR experience. Nurses were asked to report the clinical utility.

MAIN OUTCOMES AND MEASURES

Patients self-reported pain using a visual analog scale (VAS; range, 0-100). A researcher observed patient pain based on the Face, Legs, Activity, Cry, and Consolability-Revised (FLACC-R) scale. Nurses were asked to report VR helpfulness (range, 0-100; higher scores indicate more helpful) and ease of use (range, 0-100; higher scores indicate easier to use).

RESULTS

A total of 90 children (45 [50%] girls, mean age, 11.3 years [95% CI, 10.6-12.0 years]; 51 [57%] White children) participated. Most children had second-degree burns (81 [90%]). Participants in the active VR group had significantly lower reported overall pain (VAS score, 24.9 [95% CI, 12.2-37.6]) compared with participants in the standard care control group (VAS score, 47.1 [95% CI, 32.1-62.2]; P = .02). The active VR group also had a lower worst pain score (VAS score, 27.4 [95% CI, 14.7-40.1]) than both the passive VR group (VAS score, 47.9 [95% CI, 31.8-63.9]; P = .04) and the standard care group (VAS score, 48.8 [95% CI, 31.1-64.4]; P = .03). Simulator sickness scores (range, 0-60; lower scores indicate less sickness) were similar for active VR (19.3 [95% CI, 17.5-21.1]) and passive VR groups (19.5 [95% CI, 17.6-21.5]). Nurses also reported that the VR games could be easily implemented in clinics (helpfulness, active VR: 84.2; 95% CI, 74.5-93.8; passive VR: 76.9; 95% CI, 65.2-88.7; ease of use, active VR: 94.8, 95% CI, 91.8-97.8; passive VR: 96.0, 95% CI, 92.9-99.1).

CONCLUSIONS AND RELEVANCE

In this study, a smartphone VR game was effective in reducing patient self-reported pain during burn dressing changes, suggesting that VR may be an effective method for managing pediatric burn pain.

Use of a superabsorbent dressing in the management of exudate in hard-to-heal wounds

With the shift in demographics towards an ageing population with multimorbidity, the number of hard-to-heal (chronic) wounds is increasing each year. This poses a challenge for both health professionals, for whom wound management is becoming more complex, and for patients, who have to cope with exudate production, malodour and pain. This article summarises understanding of healing in such wounds and how best to meet the challenge of exudate, which is a ubiquitous hallmark of hard-to-heal wounds. The role of superabsorbent dressings is considered, with particular reference to Kliniderm superabsorbent in the management of people with these challenging wounds.

Assessment and management of pain during dressing change in patients with diabetic foot ulcers: a best practice implementation project

INTRODUCTION

Pain caused by dressing change has adverse effects on patients with a diabetic foot ulcer, including sleep disturbances, immobility, depression and anxiety. It is crucial that healthcare professionals use a standardized tool to assess and document pain during dressing change and then use this information to inform strategies to alleviate the pain.

OBJECTIVES

The aim of this project was to implement evidence-based practice in assessment and management of pain during dressing change among patients with diabetic foot ulcers in an endocrinology unit in a tertiary hospital.

METHODS

The JBI Practical Application of Clinical Evidence System (JBI PACES) and Getting Research into Practice (GRiP) audit and feedback tool were used for auditing clinical practice and translating evidence into practice. A baseline audit was performed to assess compliance with six criteria, followed by the implementation of evidence-based interventions to improve compliance. The follow-up audit using the same audit criteria was conducted to assess the effect of targeted strategies on compliance with best practice.

RESULTS

The baseline audit revealed that compliance with evidence-based practice was low, with only one of the six audit criteria achieving a compliance rate above 60%. After brainstorming and synthesizing the literature, the project team identified barriers and strategies for implementing best practice. The follow-up audit showed improvements in compliance across all six criteria, although there was only a small improvement in one of the criteria. The compliance rate of the other five criteria improved to greater than 67%.

CONCLUSION

A best practice implementation project that involved standardizing pain assessment and management, and delivering education materials to nursing staff and patients was completed using JBI PACES and GRiP. The project improved nurses' compliance with best practice. Nurses attach importance to relieving patients' pain when they perform wound care, while patients with a diabetic foot ulcer gain access to high-quality wound care. Future studies will be conducted to address new barriers that emerged during the follow-up audit.

An evaluation of short-stretch compression systems for chronic lower-limb leg ulcers

An evaluation of a new short-stretch compression system (CoFlex UBZ, TLC and TLC Lite, Aspen Medical Europe Ltd) was undertaken in four leg ulcer clinics. A total of 19 patients aged 42-93 years were treated for up to 4 weeks, or until healed. Collated data included age, underlying diseases, leg ulcer type, ulcer duration and current treatment. The evaluation included quality of life measurements, wear time, slippage, exudate strikethrough and pain using a numerical pain score. Patients were asked to document sleep patterns. Compression was applied according to clinical need. Inclusion criteria were non-healing wounds on the lower limb existing for more than 6 weeks that were suitable for compression. Exclusion criteria included patients with untreated peripheral disease, ankle-brachial pressure index (ABPI)<0.5 or those unable to consent. Staff were asked to rate performance, wear time, fluid handling and conformability. Wound tissue types improved significantly for n=16 (84%) patients. Pain scores reduced significantly by week 2, n=11 (58%) patient leg ulcers had improved, n=2 (11%) patients in standard compression noted a marked reduction in malodour and sloughy tissue. n=16 (84%) rated the overall performance as 'very good' or 'good'. A detailed cost analysis was undertaken on one patient, suggesting a potential cost saving of £186.92 per month and a cost efficiency saving of 43.4%.

Holistic wound assessment in primary care

Wound care is expensive and can cause immeasurable stress and inconvenience to patients and their significant others. It is therefore in the best interest of the patient, their significant others and the NHS as a whole that wounds are expertly assessed, managed and healed in the quickest timeframe possible. Nurses play a pivotal role in the process of accurate holistic wound assessment, evaluation and treatment. This article aims to help further develop and enhance both professional and clinical wound care assessment and evaluation skills. Pertinent wound care literature is critically reviewed and the crucial nature and important components of comprehensive wound assessment for facilitating the highest possible quality wound care to patients are presented alongside recommendations regarding how the enhanced knowledge and skills could be applied into everyday wound care practice.
