In addition to its low toxicity risk, Lavender (Lavandula angustifolia Mill.) essential oil is recognised worldwide for its sedative, antidepressant, antiseptic, antifungal, relaxing, and antiemetic properties. Thus, the action mechanism of lavender oil has attracted significant attention from researchers interested in improving the physical, emotional, and spiritual well-being of patients. To investigate the scope of knowledge regarding the use of L. angustifolia essential oil as a complementary therapy in adult health care. A scoping review was carried out using a PRISMA-ScR checklist followed by a critical assessment being performed using the Joanna Briggs Institute level of evidence. The following databases were used: SCOPUS, MEDLINE/PubMed, Web of Science, Science Direct, SCIELO, Cochrane Library, LILACS, Wiley Online Library, CAPES, and FIOCRUZ Dissertations. Eighty-three articles published between 2002 and 2022 were selected for the analysis; More articles came from Iran than from any other country and most articles reported clinical trials. The applicability of lavender essential oil and its route of administration in different clinical situations were the main topics addressed in the articles. Most studies demonstrate the efficacy of L. angustifolia Mill. essential oil in relieving pain and decreasing anxiety. Few studies evaluated the anti-psoriatic, anti-toxoplasmotic, and wound healing properties and the protective actions against cerebral ischemia. One study reported on its safety, specifically the allergenic potential of linalool, the main chemical component of L. angustifolia essential oil. However, most studies did not involve the extensive investigations on this topic or report the safe quantities of this oil for human treatment, meaning further research into the safety of this treatment is required.

To synthesize the knowledge published in the literature on the use of Integrative and Complementary Health Practices in Adult Intensive Care Units. An integrative literature review based on Ganong's theoretical-methodological framework. Data collection was carried out in January 2023 using the descriptors Intensive Care Units and Complementary Therapies, crossed using the Boolean operator “AND”. Twenty-five studies were selected and uploaded to Endnote Web. QDA Miner Lite software was used to assist in the analysis of the results. The inclusion criteria were: complete original articles, available online and detailing Integrative and Complementary Health Practices applied in the setting of Adult Intensive Care Units. Excluded works included: publications in conference and event annals; literature review articles; editorials; and study protocols. The studies date back to 1994, mostly constituted by quantitative clinical trials. Music therapy was prevalent, presented fewer difficulties in application and greater acceptance by participants. The combination of complementary practices also proved to be effective. There is a growing interest in the application of Integrative and Complementary Health Practices (ICHPs) in the Intensive Care Unit (ICU) setting. However, more research is needed to understand the impact of each practice. Moreover, nursing is essential for the effective implementation of ICHPs.

Objective: to map, in the scientific literature, the use of audiovisual aids as an educational strategy during the preoperative period of cardiac surgery. Method: a scoping review following the Joanna Briggs Institute methodology. Two independent reviewers analyzed the studies, applying the exclusion and inclusion criteria in the search by the audiovisual aid, cardiac surgery and preoperative care variables, including those that answered the research question. Results: final sample of nine studies, where the most used audiovisual aids were videos followed by apps, used because they are easily accessible and democratic. Such tools in health education optimize the team's time and promote patient education, improving the postoperative period, in addition to reducing risks and improving adherence to the treatment. Conclusion: it was possible to map the audiovisual aids used in the health education of surgical patients, such as videos, apps and information systems. These tools facilitate Nursing guidelines in the preoperative period of cardiac surgeries, increasing the patient's knowledge about the surgery.

Objectives: to map the strategies for managing thirst in postoperative adult patients. Methods: scoping review was conducted in October 2021 in 19 data sources: 14 databases and 5 platforms to search in the grey literature. It was prepared according to the recommendations of the Joanna Briggs Institute and the checklist of the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews. Nine selected articles were part of the final sample. Results: there is evidence of strategies to manage postoperative thirst using interventions such as water, ice, mentholated measures, carbohydrate and protein enriched fluid, oral hydrator, flavored gargling, cold gargling, wet gauze, 0.75% citric acid spray, and cold water. Final Considerations: the strategies observed may be reduced to cold and menthol use, salivary stimulants, and early introduction of fluids. The outcomes were positive in all the studies reviewed.

Objective: to describe the content construction and validation process of the Distance Education Basic Life Support Course. Method: methodological study, developed through literature review, outlined in the light of the Bloom's Taxonomy and Ausubel's Meaningful Learning Theory. For validation, the analysis was performed with judges, using a structured tool. Results: the construction of the distance course was complex and challenging, since it was tried to develop it with logical-methodological coherence, considering the constructivist perspective, representing an advance in the process of dissemination of the Urgency and Emergency teaching culture. As for the content validation process, it was verified that of the 16 suggestions made by the judges, 14 were accepted and two rejected. Conclusion: the course had its contents validated by experts.

Objectiveto evaluate the effectiveness of using music to relieve pain, anxiety, and change in vital signs in adult and older adult patients undergoing cardiac catheterization. Methodsthis is a systematic review with meta-analysis carried out in October 2022, using 12 data sources, without time or language restrictions. The study followed the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The “Risk-of-bias tool” was used to assess the risk of bias, the “R CORE Team program: A language and environment for statistical computing” was used to perform the meta-analysis, and the “Grading of Recommendations Assessment, Development and Evaluation” was used to assess the quality of evidence in the studies. a total of nine studies were included, totaling 1456 participants. The most used tools for measuring anxiety were the State-Trait Anxiety Inventory and Numerical Rating Scale. This was also used to measure pain, in addition to the Visual Analogue Scale. The use of instrumental, classical and relaxing music prevailed, applied using headphones during the painful procedure, at a frequency of 60 to 100bpm and sound intensity of 60–70 dB. There was statistical significance in the use of music in reducing pain, anxiety and systolic blood pressure. music interventions are effective in relieving pain, reducing systolic pressure and anxiety, but indifferent in terms of heart rate, respiratory rate and diastolic pressure. They provide humanization of care, can reduce hospital costs and length of hospital stay.
