Relaxation Therapy with Guided Imagery for Postoperative Pain Management: An Integrative Review.

OBJECTIVE: To identify the evidence in the literature about relaxation therapy with guided imagery for postoperative pain management. METHOD: Integrative review. DATA SOURCE: PubMed, Lilacs, Cochrane, Embase, Web of Science, Scopus and Cinahl, between August 2006 and December 2016. Descriptors: Postoperative Pain, Imagery (Psychotherapy) and Guided Imagery. STUDY SELECTION: original studies published in English, Spanish and Portuguese. 291 studies were identified and eight were selected. Descriptive data analysis, presented in detail, with a summary of the knowledge produced in each study. RESULTS: In the primary studies included, the use of guided imagery associated with other complementary therapies was highlighted: hand and foot "M" technique, education on postoperative pain management with analgesic drugs, relaxation exercises, respiration exercises, meditation, soothing biorhythmic music combined with positive and encouraging assertions and music with nature sounds. CONCLUSIONS: The knowledge synthesis resulting from this study indicates that evidence could be identified on the use of guided imagery associated with relaxation therapy as a complementary approach to drug analgesia in postoperative pain control strengthens its indication for nursing practice. This evidence, however, demonstrates that the quality of the use of this therapy is limited, and it is necessary to carry out new randomized clinical studies to fill the existing gaps in this topic.

Guided imagery relaxation therapy on preoperative anxiety: a randomized clinical trial.

OBJECTIVE: to evaluate the effect of relaxation therapy with guided imagery on state anxiety and cortisol in the immediate preoperative period in patients submitted to bariatric surgery by videolaparoscopy. METHOD: a randomized, triple-blind clinical trial in a large teaching hospital in the interior of Minas Gerais. Twenty-four patients who would undergo video-laparoscopic bariatric surgery were randomly allocated in two groups, namely 12 in the control group and 12 in the experimental group. State anxiety was assessed by the State-Trait Anxiety Inventory, and blood cortisol levels were measured before and after the intervention or standard care. Descriptive analyzes were used for the quantitative variables and Student's t-test for independent samples, in the analysis of the differences between the state anxiety scores and cortisol levels. RESULTS: the experimental group presented a statistically significant reduction of the state anxiety scores (p = 0.005) as well as of cortisol levels (p <0.001) after the intervention. CONCLUSION: guided imagery relaxation therapy is an effective nursing intervention for the reduction of state anxiety and blood cortisol levels in the preoperative period in patients undergoing video-laparoscopic bariatric surgery.

Objetivo avaliar o efeito da terapia de relaxamento com imagem guiada sobre a ansiedade-estado e o cortisol no pré-operatório imediato, em pacientes submetidos à cirurgia bariátrica por videolaparoscopia. Método ensaio clínico randomizado, triplo-cego, realizado em um hospital de ensino de grande porte, no interior de Minas Gerais. Foram alocados aleatoriamente 24 pacientes que foram submetidos à cirurgia bariátrica por videolaparoscopia (12 no grupo controle e 12 no grupo experimental). A ansiedade-estado foi avaliada pelo Inventário de Ansiedade Traço-Estado, e os níveis de cortisol sanguíneo foram dosados, antes e após a aplicação da intervenção ou cuidados-padrão. Análises descritivas foram usadas para as variáveis quantitativas e teste t de Student para amostras independentes, na análise das diferenças entre os escores de ansiedade-estado e níveis de cortisol. Resultados o grupo experimental apresentou redução estatisticamente significativa dos escores de ansiedade-estado (p=0,005), bem como dos níveis de cortisol (p<0,001), após a intervenção. Conclusão a terapia de relaxamento com imagem guiada apresenta-se como uma intervenção de enfermagem eficaz para a redução da ansiedade-estado e níveis de cortisol sanguíneo, no período pré-operatório, em pacientes submetidos à cirurgia bariátrica por videolaparoscopia.

Objetivo evaluar el efecto de la terapia de relajación con imagen guiada sobre la ansiedad-estado y el cortisol en el preoperatorio inmediato en pacientes sometidos a cirugía bariátrica por videolaparoscopia. Método ensayo clínico aleatorizado, triple-ciego, realizado en un hospital de enseñanza de gran porte, en el interior de Minas Gerais. Se asignaron al azar 24 pacientes para ser sometidos a la cirugía bariátrica por videolaparoscopia (12 en el grupo control y 12 en el grupo experimental). La ansiedad como estado fue evaluada por el Inventario de Ansiedad Rasgo y Estado, y los niveles de cortisol sanguíneo fueron dosificados, antes y después de la aplicación de la intervención del cuidado estándar. Los análisis descriptivos se utilizaron para las variables cuantitativas y la prueba t de Student para muestras independientes, en el análisis de las diferencias entre los escores de ansiedad como estado y los niveles de cortisol. Resultados el grupo experimental presentó una reducción estadísticamente significativa de las puntuaciones de ansiedad como estado (p = 0,005), así como de los niveles de cortisol (p <0,001), después de la intervención. Conclusión la terapia de relajación con imagen guiada se presenta como una intervención de enfermería eficaz para la reducción de la ansiedad como estado y niveles de cortisol sanguíneo, en el período preoperatorio en pacientes sometidos a la cirugía bariátrica por videolaparoscopia.
