RESUMEN
Degloving is a type of avulsion injury that leads to the separation of the skin from its underlying tissues. It is usually caused by industrial machinery through smashing or traction mechanisms, where the patient typically tries to avoid severe trauma by pulling their hand off, resulting in this particular injury. Although free flaps have now become the standard of treatment in many institutions, the lack of this possibility makes pedicled flaps a good reconstructive option, with advantages such as low donor-site morbidity, low procedure costs, and relatively easy dissection of the flap. Since the description of the pedicled groin flap technique by McGregor and Jackson, this reconstructive option has become a versatile flap for the coverage of wounds on the hand and distal forearm. This axial-patterned cutaneous flap is based on the superficial circumflex arteriovenous system, which can provide soft-tissue coverage for moderate-to-severe injuries, especially those caused by work accidents. This article aims to describe our experience in treating five different cases of traumatic degloving hand injuries using a groin flap for coverage, with excellent aesthetic and functional results. Two of these cases resulted from degloving after a traction accident, one from a firework explosion, one from a gunshot, and finally, one as a result of an electric wound.
RESUMEN
Background: Choosing adequate topical antimicrobial agents in burn patients still represents a challenge. Therefore, this systematic review was conducted to compile and evaluate current recommendations in international clinical practice guidelines (CPGs) to develop more consistent clinical guidance. Methods: A systematic search for CPGs was conducted independently by two reviewers using PubMed, EMBASE, Google Scholar, and external citations. The quality of the selected CPGs was evaluated separately using the AGREE II instrument, and intraclass correlation coefficients were calculated. Statistical analysis was performed using R V 1.4.1 statistical software. Results: Eleven CPGs were included in the study. Most guidelines tend to recommend silver-containing dressings over antiseptics or antibiotics, regardless of the depth of the burn. Silver sulfadiazine is the most recommended topical antimicrobial in low-resource settings. An overall mean appraisal AGREE II score of 68.2% was obtained. The global intraclass correlation coefficient was 0.62 (95% confidence intervals 0.54-0.69), which corresponds to a substantial global concordance between both appraisers. Conclusions: Great heterogeneity was found between recommendations and CPGs. The three determining factors considered to issue a recommendation were the clinical scenario, burn-wound depth, and burn severity. There is consensus among the guidelines to use topical antimicrobials as a tool to prevent infection, and most of these recommend the use of silver-containing dressings for most scenarios. However, there is currently no ideal topical antimicrobial agent that can be recommended for all clinical scenarios. The development of more consistent recommendations is warranted to standardize clinical practice.
