Trial Summary

What is the purpose of this trial?

To compare the rate of wound complications with the PICO dressing versus a standard nonstick gauze dressing in patients undergoing anterior total ankle arthroplasty.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications.

What data supports the effectiveness of the PICO dressing treatment for total ankle replacement recovery?

Research shows that the PICO dressing, a type of negative pressure wound therapy, has been effective in reducing complications like infections and wound reopening in various surgeries, including lower extremity amputations. This suggests it may help improve recovery after total ankle replacement by promoting better wound healing. ^{1 2 3 4 5}

Is the PICO dressing generally safe for use in humans?

The PICO dressing has been used in various surgeries and wound treatments, and studies suggest it is generally well accepted by patients. Some concerns include fear of dropping the pump and initial uncertainty, but no major safety issues have been reported. ^{1 2 3 4 5}

How is the PICO dressing treatment different from other treatments for total ankle replacement recovery?

The PICO dressing is a unique treatment because it uses negative pressure wound therapy (NPWT) to help heal surgical wounds by reducing complications like infections and wound dehiscence (wound reopening). It is a portable, single-use system that requires fewer dressing changes compared to traditional methods, making it more convenient for outpatient care. ^{1 2 3 4 5}

Treatment Details

Interventions

• PICO dressing

Trial Overview The trial is testing if a PICO dressing—a single-use negative pressure therapy system—reduces wound complications better than standard non-stick gauze after total ankle arthroplasty (ankle replacement surgery).

Participant Groups

Group I: Group 2 (Treatment group) Experimental Treatment 1 Intervention

Surgical wound will be covered with the PICO dressing.

Group II: Group 1 (Control group) Active Control 1 Intervention

Surgical wound will be covered with the standard non-stick gauze dressing.

Findings from Research

The PICO negative pressure wound therapy (NPWT) dressing was successfully used on 21 patients with various postoperative or posttraumatic wounds, demonstrating effective healing with a median treatment duration of 16 days.

Using the PICO dressing in an outpatient setting not only improved patient care by promoting faster healing but also saved hospital costs by reducing the need for inpatient stays, totaling 24 bed days saved.

Application of the Single Use Negative Pressure Wound Therapy Device (PICO) on a Heterogeneous Group of Surgical and Traumatic Wounds. Payne, C., Edwards, D.[2022]

The use of the PICO system for incisional negative-pressure wound therapy after lower extremity amputation (LEA) showed a lower incidence of postoperative wound complications, such as surgical site infections (SSIs) and wound dehiscence, compared to conventional dressings (12.5% vs 43.8%).

No cases of deep SSIs were reported in the PICO dressing group, indicating its potential effectiveness in enhancing wound management outcomes, despite the study's limitations of being retrospective and having a small sample size of 32 patients.

Effectiveness of Specific Single-Use Incisional Negative Pressure Wound Therapy (PICO System) After Major Lower Extremity Amputation. Takahashi, H., Takeda, S., Tanaka, Y., et al.[2023]

The PICO™ dressing, which uses negative pressure wound therapy, was generally well accepted by patients after vascular surgery, indicating its potential effectiveness in reducing surgical site infections.

Patients reported some concerns, such as fear of dropping the pump and a lack of information, but those who used both the PICO™ and standard dressings preferred the PICO™ dressing, suggesting a positive patient experience.

Patients' Experiences Using Closed Incision Negative Pressure Wound Therapy Dressing After Infra-Inguinal Vascular Surgery. Nyman, J., Acosta, S., Monsen, C., et al.[2022]

Patients with stoma closure wounds treated with the PICO dressing required significantly fewer visits to community nurses (1.9 visits) compared to those with traditional packing (11.9 visits), indicating improved convenience and potentially better management of the wound.

The majority of patients using the PICO dressing were able to return to work or daily activities within 1 to 2 weeks, suggesting that this negative pressure wound therapy may enhance recovery times for stoma closure wounds.

Negative pressure therapy for stoma closure sites-a nonrandomised case control study. Obeid, N., Sharma, E., Dunstan, M., et al.[2021]

In a study involving 188 moderate-risk patients undergoing laparotomy, the use of PICO dressings did not significantly reduce the rate of surgical site infections compared to standard dressings, with 14% of patients in both groups developing infections.

While there was a trend towards fewer overall surgical site complications in the PICO group (11 complications) compared to the standard dressing group (20 complications), this difference was not statistically significant, suggesting that PICO dressings may not provide a clear benefit in this context.
