Platelet-rich plasma for the treatment of burn wounds: A meta-analysis of randomized controlled trials

BackgroundTo evaluate the efficacy and safety of platelet-rich plasma in the treatment of burn wounds through a meta-analysis of randomized controlled trials.MethodsWe conducted a comprehensive study from electronic medical journal databases. The primary outcome was healing rate, and the secondary outcomes were healing time, adverse events, pain score and scar score. The data was analyzed using Review Manager 5.3 and Stata 12. The odds ratio (OR) among different groups was calculated by using 95 % confidence interval (CI).ResultsWe included 8 randomized controlled trials with a total of 539 patients. The results showed that platelet-rich plasma could improve the healing rate of burn wound (OR 4.43, 95 % CI 2.13–9.22). The wound healing time of the platelet-rich plasma treatment group was significantly shorter than that of the conventional treatment group (OR –4.23, 95 % CI ?5.48 to ?2.98), both the superficial burn (OR –3.80, 95 % CI ?4.53 to ?3.07) and the deep burn group (OR –4.65, 95 % CI ?6.90 to ?2.40) had shorter healing time. Otherwise, the incidences of adverse events (OR 0.30, 95 % CI 0.11?0.78), pain score (OR –0.80, 95 % CI ?1.40 to ?0.21) and scar score (OR –0.38, 95 % CI ?0.69 to ?0.07) were all better in the platelet rich plasma treatment group.ConclusionTopical platelet-rich plasma treatment on burn wounds can improve wound healing and reduce the incidence of adverse events. Further research is needed to standardize the preparation and use of platelet-rich plasma and to evaluate the long-term clinical outcome of platelet-rich plasma in the treatment of burn wounds.

Pain control in a randomized, controlled, clinical trial comparing moist exposed burn ointment and conventional methods in patients with partial-thickness burns

Conventional management of partial-thickness burn wounds includes the use of paraffin gauze dressing, frequently with topical silver-based antibacterial creams. Some creams form an overlying slough that renders wound assessment difficult and are painful upon application. An alternative to conventional management, moist exposed burn ointment (MEBO), has been proposed as a topical agent that may accelerate wound healing and have antibacterial and analgesic properties. One hundred fifteen patients with partial-thickness burns were randomly assigned to conventional (n = 58) or MEBO treatment (n = 57). A verbal numerical rating score of pain was made in the morning, after burn dressing, and some 8 hours later. Patient pain profiles were summarized by locally weighted regression smoothing technique curves and the difference between treatments estimated using multilevel regression techniques. Mean verbal numerical rating scale pain levels (cm) in week 1 for all patients were highest at 3.2 for the after dressing assessment, lowest in the evening at 2.6, and intermediate in the morning at 3.0. This pattern continued at similar levels in week 2 and then declined by a mean of 0.5 in all groups in week 3. There was little evidence to suggest a difference in pain levels by treatment group with the exception of the postdressing pain levels in the first week when those receiving MEBO had a mean level of 0.7 cm (95% confidence interval, 0.2 to 1.1) lower than those on conventional therapy. MEBO appeared to bring greater pain relief for the postdressing assessment during the first week after burns. This initial relief, together with comparable pain levels experienced on other occasions, indicates that MEBO could be an alternative to conventional burns management.     

Preparation of asiaticoside-loaded coaxially electrospinning nanofibers and their effect on deep partial-thickness burn injury

Sodium alginate and chitosan were in favor of wound healing. However, the two polymers were not compatible in one formulation due to the electrostatic interaction. Coaxially electrospinning technology could make two or more noneletrospun polymers to be electrospun in independent core and shell layer. Asiaticoside-loaded coaxially electrospinning nanofibers of alginate, polyvinyl alcohol (PVA) and chitosan (alginate/PVA/chitosan) were prepared and evaluated. Morphologies and microstructure of nanofibers were observed with scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Drug release in vitro of coaxial nanofibers was also evaluated. Deep partial-thickness burn injury were established and used to evaluate the improved healing effect of asiaticoside-loaded coaxial nanofibers. Drug-loaded coaxial nanofibers prepared with the optimized formulations and technologies had the obvious core-shell structure. Coaxial nanofibers showed faster drug release profiles in vitro and this facilitated wound healing. Its healing effect on rats with deep partial-thickness burn injury was also significant based on morphology, wound healing ratio, and pathological sections. Positive expression of vascular endothelial growth factor (VEGF), cluster of differentiation 31 (CD31), and proliferating cell nuclear antigen (PCNA), and down regulation of tumor necrosis factor (TNF) and interleukin-6 (IL-6) also validated the improved effect of wound healing. In general, the asiaticoside-loaded coaxial nanofibers had obvious core-shell structure with smooth surface and uniform diameter. Its healing effect on deep partial-thickness burn injury of rats was obvious. Asiaticoside-loaded coaxial nanofibers provide a novel promising option for treatment of deep partial-thickness burn injury.

Burn center management of necrotizing fasciitis

Necrotizing fasciitis is a rapidly progressive soft-tissue infection associated with significant morbidity and mortality. Necrotizing fasciitis is similar to invasive burn wound infection in that diagnosis requires histologic examination of affected tissue and treatment requires aggressive surgical debridement followed by skin autograft. Transfer to a burn center facilitates the management of necrotizing fasciitis, where requisite surgical and nursing expertise is available. We reviewed the experience of one burn center in the management of necrotizing fasciitis over a 5-year period. Ten patients were transferred to the burn center from other medical facilities for care, arriving a mean of 8.9 days after initial hospital admission. The diagnosis was made by a surgical service or consultation before transfer in all cases; initial admission to a medical rather than a surgical service delayed surgery in five cases. All patients had surgical debridement before transfer but required a mean of 5.1 additional operations at the burn center. Although the mean extent of involvement was 14.8% body surface area, the mean length of burn center stay was 34.9 days. Complications were frequent, including pulmonary failure requiring mechanical ventilation (n = 6), renal insufficiency or failure (n = 5), hypotension requiring pressers (n = 4), deep venous thrombosis (n = 3), and pulmonary emboli (n = 1). Overall mortality was 2 of 10 patients (20%). Both fatalities were associated with delay in initial surgical procedure and in transfer to the burn center. The similarity of necrotizing fasciitis and invasive burn wound infection makes the burn center the ideal setting for the treatment of this disease. We advocate the addition of necrotizing fasciitis to the list of conditions currently recognized by the American Burn Association as appropriate for burn center transfer and care.     

Collagen‐cellulose nanocrystal scaffolds containing curcumin‐loaded microspheres on infected full‐thickness burns repair

Burn infection is a serious problem that delays wound healing and leads to death. Curcumin (Cur) has been shown to exhibit antioxidant, anti‐inflammatory, antimicrobial and anticarcinogenic activity. However, its instability, extremely low aqueous solubility and bioavailability in physiological fluids may make it difficult to maintain local Cur concentrations above the minimum inhibitory concentration for burn infection treatment. The objective of this study was to construct complexes of Cur/gelatin microspheres (GMs) and porous collagen (Coll)‐cellulose nanocrystals (CNCs) composite scaffolds for full‐thickness burn infection treatment. The Cur/GMs/Coll‐CNCs scaffolds had high porosity, available pore size, and a long and sustained Cur release profile. Furthermore, the composite scaffold exhibited remarkably strong antibacterial activity. Hence, we evaluated the wound‐healing effects and antibacterial properties of Cur/GMs/Coll‐CNCs scaffolds in a rat full‐thickness burn infection model. The Cur/GMs/Coll‐CNCs scaffold was able to prevent not only local inflammation but also accelerated dermis regeneration. Thus, we conclude that Cur/GMs/Coll‐CNCs scaffolds can act as an effective dermal regeneration template for full‐thickness burn wound infection healing in rats models.
