Pain Neuroscience Education in elective surgery patients: study protocol for a randomised controlled trial.

BACKGROUND: Pain Neuroscience Education (PNE) consists of an educational strategy that seeks to understand the biological processes of pain and how to control it. The main objective of this study will be to evaluate the impact of PNE on outcomes related to the postoperative period. The hypothesis is that the intervention may positively influence postoperative recovery, contributing to pain control, clinical indications, acceptance and consumption of analgesics and other pharmacological drugs that contribute to its control, as well as psychological aspects, such as anxiety, depression and pain catastrophising. METHODS AND ANALYSIS: This will be an open, parallel, multicentre and randomised controlled clinical trial. A total of 100 participants aged between 18 and 59 years of age, of both genders, who are going to have elective general surgery will be evaluated. The intervention group will participate in a preoperative pain neuroscience educational session and also receive usual preoperative care, while the control group receives usual preoperative care as well. The educational session will last 30 min and consists of a video (5:20 min), a questionnaire about the content, time for participants to express their beliefs, thoughts and doubts. Participants will be evaluated preoperatively and there will be one postintervention evaluation. The intensity and characteristics of pain and anxiety are evaluated as primary outcomes. As secondary outcomes, pain catastrophising and depression are taken into account. ETHICS AND DISSEMINATION: The project was approved by the Research Ethics Committee of the Faculty of Ceilandia, the Research Ethics Committee of the Institute of Strategic Health Management of the Federal District and the Research Council of the Hospital of Brasília-Rede Dasa (CAAE: 28572420.3.0000.8093). Recruitment began in June of 2023. All participants were included in the study only after their written consent. All data obtained will be analysed and distributed through publication in journals and at scientific events. TRIAL REGISTRATION NUMBER: Brazilian Registry of Clinical Trials (ReBEC) (RBR-23mr7yy).

A systematic review of the added value of perioperative pain neuroscience education.

OBJECTIVE: To identify and summarize evidence about the benefits of perioperative pain neuroscience education (PNE) on pain-related and psychosocial outcomes. METHODS: Included were reports written in English that carried out PNE or its synonyms; perioperative period; aged ≥ 18 years; interventional studies and observational studies. Secondary studies, conference abstracts, and editorials were excluded. There was no time limitation. INFORMATION SOURCES: PubMed, Virtual Health Library, Cochrane Library, and Science Direct. Search: June 20th 2023. The risk of bias was assessed using the Joanna Briggs Institute checklists, and synthesis followed the recommendations of the Synthesis Without Meta-analysis (SWiM) guideline. Register: Center for Open Science website (10.17605/OSF.IO/ZTNEJ). RESULTS: The sample consisted of 18 reports. For pain outcomes, it was not possible to attribute PNE benefits because ten reports found improvements in both intervention and control groups. For psychosocial outcomes, fourteen reports found benefits for PNE groups. All the analyzed reports showed low risk of bias. CONCLUSION: PNE had additional benefits beyond those obtained with conventional treatment for psychosocial outcomes. PRACTICAL IMPLICATIONS: Due to the lack of evidence, it was not possible to indicate the clinical use of PNE. It is suggested that further studies are needed aimed at clarifying the possible benefits.

Aromatherapy with oil of Lavandula angustifolia for pain in women: scoping review / Aromaterapia com óleo essencial de Lavandula angustifolia para dor em mulheres: revisão de escopo

ABSTRACT BACKGROUND AND OBJECTIVES: Aromatherapy with lavender essential oil has been used to reduce pain, anxiety, nausea and vomiting, among others. As the painful experience is unique, responses to therapeutic approaches may vary among individuals and there are specific conditions related to women's health that deserve to be examined. The objective of this study was to analyze the uses of aromatherapy with essential oil of lavender (Lavandula angustifolia), by nurses, for pain control in women. CONTENTS: This is a scoping literature review. The search was carried out in the following portals and/or databases: BVS, Pubmed, Cochrane, on June 3, 2022, and was updated on June 9, 2023. The sample consisted of four controlled clinical trials addressing aromatherapy with lavender essential oil in the "inhalation" and "massage" modalities, to treat acute labor pain and dysmenorrhea. In all studies, the intervention provided a reduction in pain without unwanted effects (p<0.05) and the nurse participated as a member of the multidisciplinary team. CONCLUSION: Aromatherapy with lavender essential oil during labor and dysmenorrhea proved to be effective in reducing pain in the analyzed sample.

RESUMO JUSTIFICATIVA E OBJETIVOS: A aromaterapia com óleo essencial de lavanda tem sido utilizada para redução de dor, ansiedade, náuseas e vômitos, dentre outros. Assim como a experiência dolorosa é única, as respostas às abordagens terapêuticas podem variar entre os indivíduos e há condições específicas relacionadas à saúde da mulher que merecem ser examinadas. O objetivo deste estudo foi analisar os usos da aromaterapia com óleo essencial de lavanda (Lavandula angustifolia), por enfermeiros, no controle da dor em mulheres. CONTEÚDO: Esta é uma revisão de escopo da literatura. A busca foi realizada nos seguintes portais e/ou bases de dados: BVS, Pubmed, Cochrane, em 03 junho de 2022, sendo atualizada em 09 de junho de 2023. A amostra foi composta de quatro ensaios clínicos controlados abordando aromaterapia com óleo essencial de lavanda nas modalidades "inalação" e "massagem", para tratar dor aguda do parto e da dismenorreia. Em todos os estudos a intervenção proporcionou redução na dor sem efeitos adversos (p<0,05) e o enfermeiro participou como integrante da equipe multidisciplinar. CONCLUSÃO: A aromaterapia com óleo essencial de lavanda no trabalho de parto e dismenorreia mostrou-se eficaz para a redução da dor na amostra analisada.
