Pain relief during wound care for patients with a deep open wound in an orthopedic trauma department: a best practice implementation project

Cell electrospinning and its application in wound healing: principles, techniques and prospects

Currently, clinical strategies for the treatment of wounds are limited, especially in terms of achieving rapid wound healing. In recent years, based on the technique of electrospinning (ES), cell electrospinning (C-ES) has been developed to better repair related tissues or organs (such as skin, fat and muscle) by encapsulating living cells in a microfiber or nanofiber environment and constructing 3D living fiber scaffolds. Therefore, C-ES has promising prospects for promoting wound healing. In this article, C-ES technology and its advantages, the differences between C-ES and traditional ES, the parameters suitable for maintaining cytoactivity, and material selection and design issues are summarized. In addition, we review the application of C-ES in the fields of biomaterials and cells. Finally, the limitations and improved methods of C-ES are discussed. In conclusion, the potential advantages, limitations and prospects of C-ES application in wound healing are presented.

Electrospun nanofibers promote wound healing: theories, techniques, and perspectives

At present, the clinical strategies for treating chronic wounds are limited, especially when it comes to pain relief and rapid wound healing. Therefore, there is an urgent need to develop alternative treatment methods. This paper provides a systematic review on recent researches on how electrospun nanofiber scaffolds promote wound healing and how the electrospinning technology has been used for fabricating multi-dimensional, multi-pore and multi-functional nanofiber scaffolds that have greatly promoted the development of wound healing dressings. First, we provide a review on the four stages of wound healing, which is followed by a discussion on the evolvement of the electrospinning technology, what is involved in electrospinning devices, and factors affecting the electrospinning process. Finally, we present the possible mechanisms of electrospun nanofibers to promote wound healing, the classification of electrospun polymers, cell infiltration favoring fiber scaffolds, antibacterial fiber scaffolds, and future multi-functional scaffolds. Although nanofiber scaffolds have made great progress as a type of multi-functional biomaterial, major challenges still remain for commercializing them in a way that fully meets the needs of patients.

Severity of Wound-Related Pain and Associated Factors Among Patients Who Underwent Wound Management at Teaching and Referral Hospital, Northwest Ethiopia

Background

Wound management is one of the commonly performed procedures in hospitals. It can be a major source of pain and pain may be a frequently experienced but under-considered component of wound management. Therefore, we aimed to determine the severity of wound-related pain and identifying factors associated with it among patients who underwent wound management.

Patients and Methods

An institutional-based, cross-sectional study was conducted from March to May, 2020 in the University of Gondar Comprehensive Specialized Hospital. A total of 424 patients were included in this study. Data were collected by direct observation, chart review, and interview of patients by using questionnaires. Statistical analysis had performed using SPSS 25.00 version statistical software. Descriptive statistics were conducted to summarize patients’ information and to determine the prevalence of pain. Bi-variable analysis was performed to determine each of the independent variables and only variables with a P-value<0.2 were entered into the multivariable analysis. The strength of the association was present by odds ratio and 95% Confidence interval. P-value<0.05 was consider as statistically significant.

Results

The prevalence of moderate-to-severe wound-related pain during wound management was 94.1% (95% CI=91.7–96.2). Anxiety (AOR=18.16; 95% CI=4.83–68.23), acute wound (AOR=11.49; 95% CI=1.013–130.2), baseline pain (AOR=3.51; 95% CI=1.18–10.46), and analgesia intake (AOR=0.026; 95% CI=0.001–0.895) were significantly associated with the severity of wound-related pain.

Conclusion

The prevalence of moderate-to-severe wound-related pain was considerably high. Anxiety, type of wound, baseline pain, and analgesia intake were the independent risk factors. Therefore, wound care providers should assess the severity of wound-related pain and manage accordingly. Additionally, more emphasis should be given for patients who have baseline pain, anxiety, and acute wound.
