Oxidised regenerated cellulose (ORC)/collagen dressings help maintain physiologically moist wound environments conducive to wound healing. While evidence supporting ORC/collagen dressing use exists, comprehensive assessment is needed. This systematic review/meta-analysis evaluated the performance of ORC/collagen dressings compared with standard dressings. A systematic literature search was performed using PUBMED, EMBASE, and QUOSA Virtual Library. Published studies and conference abstracts were assessed between 1 January 1996 and 27 July 2020. Comparative studies in English completed by 31 December 2019, with a study population ≥10 were included. Patient demographics, wound healing, and protease concentrations were extracted. A random-effect model was used to assess the effect of ORC/collagen dressings. Twenty studies were included following removal of duplicates and articles not meeting inclusion criteria. A statistically significant effect in favour of ORC/collagen dressings was found for wound closure (P = 0.027) and percent wound area reduction (P = 0.006). Inconclusive evidence or limited reporting prevented assessment of time to complete healing, days of therapy, number of dressing applications, pain, matrix metalloproteinase, elastase, plasmin, and gelatinase concentration. Statistically significant increase in wound closure rates and percent wound area reduction were observed in patients receiving ORC/collagen dressings compared with standard dressings in this systematic review/meta-analysis.

Negative pressure wound therapy (NPWT) and oxidized regenerated cellulose (ORC)/collagen/silver-ORC (OCSO) dressings have individually demonstrated effectiveness in supporting wound healing, but few studies have examined their combined use. This retrospective data analysis compared wound outcomes following outpatient NPWT with and without OCSO dressings. A search of deidentified records from the U.

Split-thickness skin grafts (STSG) are widely used in wound reconstruction. However, donor site wounds are created as a result. Traditionally, moist wound healing and transparent film dressings have been used to promote donor site wound healing.

Objective: The purpose of this study was to evaluate the wound healing efficacy of oxidized regenerated cellulose (ORC)/collagen dressing and ORC/collagen/silver-ORC dressings compared to standard of care or control in treatment of chronic skin wounds such as diabetic foot ulcers (DFUs), venous leg ulcers (VLUs), and pressure injuries sore ulcers (PISUs).
Methods: An electronic search was carried out in four popular databases PubMed, Scopus, Embase, and CENTRAL to identify thirteen included studies, comparing the clinical efficacy of ORC/collagen dressings when compared to control in management of chronic skin wounds, especially DFUs, VLUs, and PISUs, and skin graft donor site wounds.
Results: Consolidated data from thirteen comparative clinical studies undertaken for management of DFUs, VLUs, and PISUs showed favorable outcomes towards use of ORC/collagen compared to other traditional and hydrocolloid foam dressings in terms of wound healing rate (=0.

Complex wounds with exposed critical structures such as tendon and bone are a conundrum in wound management, especially in the setting where the patient is not a suitable candidate for flap surgery. While the individual use of negative pressure wound therapy (NPWT) and oxidised regenerated cellulose (ORC)/collagen/silver (PROMOGRAN PRISMA) dressing has been described in the literature, there are little data on the efficacy of their combined use. In this study, we describe a novel technique of combining the use of NPWT and ORC/collagen/silver dressings to manage complex wound beds as an alternative management option for patients not suitable for reconstructive flap surgery.
