Improving pressure ulcer care in intensive care units:Evaluating the impact of bundled care and silver nanoparticle dressings

BACKGROUND Pressure ulcer(PU)are prevalent among critically ill trauma patients,posing substantial risks.Bundled care strategies and silver nanoparticle dressings offer potential solutions,yet their combined effectiveness and impact on patient satisfaction remain insufficiently investigated.AIM To assess the impact of bundled care along with silver nanoparticle dressing on PUs management and family satisfaction in critically ill trauma patients.METHODS A total of 98 critically ill trauma patients with PUs in intensive care unit(ICU)were included in this study.Patients were randomly assigned to either the control group(conventional care with silver nanoparticle dressing,n=49)or the intervention group(bundled care with silver nanoparticle dressing,n=49).The PU Scale for Healing(PUSH)tool was used to monitor changes in status of pressure injuries over time.Assessments were conducted at various time points:Baseline(day 0)and subsequent assessments on day 3,day 6,day 9,and day 12.Family satisfaction was assessed using the Family Satisfaction ICU 24 ques-tionnaire.RESULTS No significant differences in baseline characteristics were observed between the two groups.In the intervention group,there were significant reductions in total PUSH scores over the assessment period.Specifically,surface area,exudate,and tissue type parameters all showed significant improvements compared to the control group.Family satisfaction with care and decision-making was notably higher in the intervention group.Overall family satisfaction was significantly better in the intervention group.CONCLUSION Bundled care in combination with silver nanoparticle dressings effectively alleviated PUs and enhances family satisfaction in critically ill trauma patients.This approach holds promise for improving PUs management in the ICU,benefiting both patients and their families.

Ultrastable in-situ silver nanoparticle dressing for effective prevention and treatment of wound infection in emergency

The use of antibacterial dressings is crucial in the prevention and treatment of wound infection in emergency sit-uations.However,the efficacy of dressings is compromised by long-term storage or exposure to harsh conditions.Here,an ultrastable in-situ silver nanoparticle dressing(AgSNP@CD)was prepared for effective prevention and treatment of wound infection in emergency.The fabrication process of AgSNP@CD is simple,suitable for large-scale production.Due to the strong interaction between the in-situ synthesized AgNPs and the cotton fabric,AgSNP@CD owned remarkable stability,thus retaining its antimicrobial efficacy even after long-term storage(up to 2 years)and under extreme conditions(damp heat,low temperatures,low-oxygen,water immersion,acid-alkali erosion).Both in vitro and in vivo results demonstrated the extraordinary antibacterial efficacy and stability of AgSNP@CD,facilitating infection prevention and wound healing in extreme conditions.In particular,AgSNP@CD exhibited a superior treatment effect on severe bacteria-infected trauma and can prevent the occur-rence of sepsis effectively.The exceptional stability and antibacterial efficacy of AgSNP@CD under complex and extreme conditions make it a well-suited dressing strategy for the prevention and treatment of wound infection in emergency.
