O objetivo do estudo foi estimar a prevalência dos incidentes ocorridos durante cirurgias em um centro cirúrgico e analisar os tipos e causas das ocorrências. Estudo transversal, retrospectivo, tendo como fonte de dados 300 prontuários de pacientes submetidos a procedimentos cirúrgicos no período de julho a dezembro de 2013, em um hospital de ensino da região Centro-Oeste do Brasil. Um total de 26 incidentes foi encontrado, estimando prevalência de 8,7%. Incidentes relacionados à suspensão de cirurgia, perfuração de luvas, acidentes com paciente por falhas técnicas no procedimento e falhas técnicas no gerenciamento do serviço foram atribuídos à distração da equipe, falha na prescrição, pouco conhecimento, sobrecarga de trabalho e falha de organização do serviço. O estudo evidenciou a característica sistêmica e multifatorial do incidente e levantou indicadores que indicam a necessidade de melhorias no processo de gestão de materiais e recursos humanos.
Purpose: To compare four commercially available hydrogel formulations in the healing of partial thickness burns experimentally induced in rats. Methods: Wistar rats were used, and after the burn wound induction they were divided into the following treatment groups: G1) NaCl 0.9%; G2) 1% silver sulfadiazine; G3) Debrigel™; G4) Safgel™; G5) Dersani™; G6) Solosite™. The animals were followed during seven, 14 and 30 days after the injury induction. Morphometric, macroscopic and microscopic evaluations were performed. Results: The treatment with Dersani™ induced better results during the inflammatory and proliferative phases of the healing process (p<0.05). The animals treated with Safgel™ presented better scaring in the remodeling phase (p<0.05), and the treatment with Dersani™ and Solosite™ induced greater wound closure (p<0.05). Conclusion: The hydrogel-based dressings presented beneficial outcomes in the healing of burn wounds experimentally induced in rats due to their ability in maintain the humidity of the wound, in removing the exudate, in promoting cell migration and collagen production during the different phases of the healing process.
To evaluate the morphometric, macroscopic and microscopic aspects of experimentally induced partial-thickness burns in rats treated with different silver-based dressings. Methods: Wistar rats were used, divided into six treatments: saline (NaCl 0.9%); silver sulfadiazine 1%; Silvercel; Mepilex Ag; Aquacel Ag and Acticoat. The animals were monitored daily and euthanized at 7, 14 and 30 days after injury induction (DAI). Results: At 7 DAI, necrosis/crust was greater in control, silver sulfadiazine and Mepilex Ag treatments, granulation tissue was induced by Aquacel Ag, polymorphonuclear infiltrate (PMN) infiltration was intensified by Mepilex Ag; mononuclear infiltrate (MN) infiltration and angiogenesis were increased by Silvercel. At 14 DAI, hemorrhage was decreased by Silvercel and Mepilex Ag, PMN infiltration increased by Acticoat. At 30 DAI, angiogenesis was greater in the Acticoat treatment and fibroblasts were increased by Acticoat and Mepilex Ag. Collagen was induced at 14 DAI by silver sulfadiazine and Aquacel Ag and, at 30 DAI, by silver sulfadiazine and Silvercel treatments. Conclusions: Silvercel and Acticoat presented better results than the other products. However, all the dressings were better than the control at some point during the process, and may contribute to the healing of partial thickness burns. Silvercel and Aquacel Ag treatments induced better cosmetic outcomes regarding wound closure and scarring.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
