Advances in Skin & Wound Care最新文献

Objective: To synthesize the literature on skin failure and pressure injuries among hospitalized patients with COVID-19.

Data sources: An electronic literature search using relevant keywords and controlled vocabulary was conducted in March 2023 on MEDLINE/PubMed, Embase, and CINAHL. Manual citation searches of included articles and grey literature, including the Wound, Ostomy, and Continence Nurses Society website were performed. Articles published in English between 2020 and April 2023 were considered.

Study selection: Articles were included if they reported on COVID-19 positive hospitalized adults with wounds that were not present upon admission. A total of 31 articles met these criteria.

Data extraction: Covidence was used to extract the data and was reviewed by multiple team members.

Data synthesis: Of the 31 studies, 27 reported new onset skin lesions during hospitalization. Wounds were classified as pressure injuries, skin failure, livedo racemosea and/or, retiform purpura, and associated with microvascular thrombosisthrombotic vasculopathy. Most pressure injuries were associated with prone position and affected patients often had multiple comorbidities including hypertension, diabetes mellitus, end-stage renal disease, heart disease, and COPD. Four articles highlighted an increased risk of new onset wounds, and three emphasized the importance of distinguishing deep tissue pressure injuries from ischemic-related lesions in patients with COVID-19.

Conclusions: The evidence suggests an increased risk of ischemic lesions and pressure injuries (PI) in patients with COVID-19 infection. This phenomenon may have inflated the numbers of PI during the pandemic and adversely affected nursing quality measures in acute care environments.

General purpose: To review the management of a patient with a chemical burn from wet cement.

Target audience: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and registered nurses with an interest in skin and wound care.

Learning objectives/outcomes: After participating in this educational activity, the participant will:1. Recognize the clinical presentation of a patient with a chemical burn from contact with wet cement.2. Describe features related to the pathophysiology of alkali burns from wet cement.3. Select the proper decontamination procedure after exposure to wet cement.4. Identify steps in the treatment of a patient with a chemical burn from contact with wet cement.

Objective: No standard definition for a completely healed wound currently exists; it is recommended that providers use a reliable wound assessment tool to determine healing. The objective of this feasibility study was to determine if a point-of-care, noncontact, near-infrared (NIR) imaging device could provide an objective measure of wound resolution and guide clinical decision-making for the optimal time to transition from protective wound dressings and gradual return to full activity.

Methods: In this single-center feasibility study, adult patients 18 years and older with a lower extremity wound of any size and etiology were seen weekly for wound assessment and standard-of-care treatment. The researchers performed serial imaging with a point-of-care, noncontact, NIR imaging device (Snapshot NIR ; Kent Imaging Inc) to assess the wound and surrounding skin and evaluated the difference in time to 100% reepithelialization on visual inspection and homogeneous tissue oxygen saturation levels at the wound site and surrounding closed skin envelope.

Results: An average time difference of 13.5 ± 10 days (median, 12 days; range, 0-35 days) was observed between 100% reepithelialization on visual wound inspection and imaging assessment. Further, NIR imaging could determine when a patient was at risk for recurrent wound breakdown.

Conclusions: The addition of point-of-care, noncontact, NIR imaging may help guide clinical decision-making for the optimal time to transition from protective wound dressings with gradual return to full activity and minimize wound recurrence.
