RESUMO
ABSTRACT Objective: To analyze the evidence available in the literature on the use of essential oils for healing and/or preventing infection in surgical wounds. Method: Systematic review according to the JBI model and PRISMA statement. The search was carried out in November/2020 and updated in December/2021, using descriptors and keywords, in the CINAHL, LILACS, CENTRAL, EMBASE, PUBMED, Scopus, and Web of Science databases. The quality of the evidence was assessed using the JBI critical appraisal tool for randomized controlled trials. Results: Five publications were included. Three studies evaluated healing and the presence of infection after episiotomy using the Redness-Edema-Ecchymosis-Discharge-Approximation (REEDA) scale; one study evaluated healing after periodontal surgery using the plaque index and Modified Gingival Index; the other four studies considered the presence of infection after episiotomy. Most studies used lavender oil, associated or not with other oils (80%). Two studies showed an improvement in healing. The infection outcome, although mentioned by 60% of studies, was not assessed as a primary outcome. Conclusion: The promising efficacy of essential oils, especially lavender, was verified in the healing of surgical wounds, especially in episiotomies.
RESUMEN Objetivo: Analizar la evidencia en la literatura sobre el uso de aceites esenciales para la cicatrización y/o prevención de infecciones en heridas quirúrgicas. Método: Revisión sistemática de acuerdo con el modelo JBI y el PRISMA. Se realizó una búsqueda en las bases de datos CINAHL, LILACS, CENTRAL, EMBASE, PUBMED, Scopus y Web of Science, en el periodo de noviembre/2020, con actualizaciones en diciembre/2021, utilizando descriptores y palabras clave. La calidad de la evidencia se evaluó por la herramienta JBI critical appraisal para ensayos controlados aleatorizados. Resultados: Se incluyeron cinco publicaciones. Tres estudios evaluaron la curación y la presencia de infección tras episiotomía mediante la escala REEDA (Redness-Edema-Ecchimosis-Discharge-Approximation); uno evaluó la curación después de cirugía periodontal utilizando el índice de placa y el índice gingival modificado; y los demás consideraron la presencia de infección posterior a la episiotomía. La mayoría de los estudios utilizaron aceite de lavanda, asociado a otros aceites o no (80%). Dos estudios demostraron mejorar la cicatrización. El resultado infección, aunque mencionado por el 60% de los estudios, no se evaluó como resultado primario. Conclusión: Se verificó la prometedora eficacia de los aceites esenciales, especialmente el de lavanda, en la cicatrización de heridas quirúrgicas, especialmente en episiotomías.
RESUMO Objetivo: Analisar as evidências disponíveis na literatura sobre o uso de óleos essenciais para a cicatrização e/ou prevenção de infecção em feridas cirúrgicas. Método: Revisão sistemática segundo modelo JBI e declaração PRISMA. Busca realizada em novembro/2020 e atualizada em dezembro/2021, utilizando-se descritores e palavras-chave, nas bases CINAHL, LILACS, CENTRAL, EMBASE, PUBMED, Scopus e Web of Science. A qualidade das evidências foi avaliada usando a ferramenta JBI critical appraisal para ensaios clínicos randomizados. Resultados: Cinco publicações foram incluídas. Três estudos avaliaram a cicatrização e presença de infecção após episiotomia por meio da escala REEDA (Redness-Edema-Ecchymosis-Discharge-Approximation); um avaliou cicatrização após cirurgia periodontal por meio do índice de placa e Índice Gengival Modificado; o restante considerou a presença de infecção após episiotomia. A maioria dos estudos utilizou o óleo de lavanda, associado ou não a outros óleos (80%). Em dois estudos houve melhora da cicatrização. O desfecho infecção, embora mencionado por 60% estudos, não foi avaliado como primário. Conclusão: Verificou-se a eficácia promissora de óleos essenciais, sobretudo do de lavanda, na cicatrização de feridas cirúrgicas, especialmente em episiotomias.

This study aimed to compare the antimicrobial action of three soaps for hand hygiene (HH): 2.0% Tea Tree Oil (TTO); 0.5% triclosan; 2.0% chlorhexidine, and to explore the perception of healthcare professionals about TTO. Two-step study: a quantitative, to determine the logarithmic reduction of Escherichia coli K12 colony-forming units before and after HH of 15 volunteers and quali-quantitative, through interviews with 23 health professionals. All the three products demonstrated antimicrobial action (a log10 reduction factor of 4.18 for TTO, 4.31 for triclosan, 3.89 for chlorhexidine, and 3.17 for reference soap). Professionals remarked the pleasant aroma and non-dryness of skin when using soap containing TTO.

AIMS AND OBJECTIVES: To analyse available research on the effectiveness of prewarming to prevent perioperative hypothermia and identify knowledge gaps for future research. BACKGROUND: Perioperative hypothermia is common and causes complications, such as coagulation and platelet function abnormalities; increased cardiac morbidity, surgical site infection, and pressure ulcer incidence levels. In this context, several methods have been investigated to prevent perioperative hypothermia, including prewarming. Prewarming is defined as the warming of peripheral tissues or the skin surface before anaesthetic induction and may consist of an active cutaneous warming system or the preoperative administration of vasodilation drugs. DESIGN: Systematic review. METHODS: We searched CINAHL, EMBASE, Cochrane Register of Controlled Trials and Medline (January 1990-November 2011) for randomised controlled trials on the effectiveness of prewarming for prevention of perioperative hypothermia, published in English, Spanish and Portuguese, and involving elective surgery patients aged 18 years or older. RESULTS: Of 730 identified studies, only 13 met the inclusion criteria. After hand-searching the reference lists of included studies, an additional study was identified for a total sample of 14 studies. The results suggest that forced-air warming system is effective to reduce hypothermia when applied for the prewarming of surgical patients. CONCLUSION: Prewarming patients with the forced-air warming system might be effective to reduce perioperative hypothermia, and new studies are needed to examine the use of carbon fibre technology. RELEVANCE TO CLINICAL PRACTICE: Nurses can use this review to inform decision-making on a prewarming programme in the perioperative period. They can also develop research on strategies to put in practice prewarming in the surgical context.
