RESUMEN

Objectives: To conduct a systematic review on the use of hypnosis in the treatment of orofacial pain. Methods: The search was performed on February 2021 and updated in July 2024 in the following databases: MEDLINE via PUBMED, Virtual Health Library (VHL), Web of Science, Cochrane Library, Embase, Clinical Trials, ISRCTN Registry, Psycinfo, Open Grey, Google Scholar, and Brazilian Digital Library of Theses and Dissertations (BDTD). The descriptors referring to Orofacial Pain and hypnosis were used to select clinical trials on the use of hypnosis in the treatment of Orofacial Pain, in English, Spanish, Portuguese, French, and Italian, without restriction on date and place of publication. In a first stage, two independent, trained, and calibrated reviewers classified the abstracts and then the full texts. The data were extracted, and the risk of bias was assessed using the Cochrane RoB 2.0 tool. Results: Of the 642 references identified, 6 studies-published between 1986 and 2010-were included in the review, with 232 patients reported. Hypnosis was mainly used in cases of chronic pain associated with temporomandibular disorders (TMDs), compared with relaxation sessions, acupuncture, occlusal splint, minimal treatment, or no interference. Hypnotherapy was applied in different ways, either exclusively by professionals or by means of self-hypnosis in a complementary or exclusive manner. All studies showed statistical significance for the effect of the intervention (hypnotherapy). The overall RoB2 consisted of three studies with high risk of bias and three studies with some concern. Conclusions: Although there were clinical studies on the subject and they had methodological flaws, hypnotherapy (induction and/or self-hypnosis) appears to be a promising strategy for the treatment of orofacial pain, especially TMDs. There is, therefore, a need for new randomized clinical studies with adequate methodological standards to confirm the findings.

RESUMEN

BACKGROUND AND PURPOSE: Fibromyalgia is a chronic syndrome marked by intense musculoskeletal pain often refractory to pharmacological treatment. Although studies have shown that hypnosis improves fibromyalgia pain, gaps in experimental design limit their reliability. This work aimed to evaluate the effects of hypnosis on pain, mental health, sleep, and quality of life in participants with fibromyalgia chronic pain. METHODS: In this prospective, parallel, randomized, controlled, blindly-evaluated trial, participants of both sexes (n = 49) diagnosed with fibromyalgia and with moderate to severe chronic pain attended 8 weekly 1-h sessions with a hypnotherapist. For the hypnosis group (n = 24), sessions consisted in induction of hypnotic trance followed by suggestions to promote analgesia. For the control group (n = 25), sessions consisted in casual unscripted conversation. Participants were assessed at baseline (7 days before), post-intervention (7 days after), and follow-up (3 months after). The primary outcome was pain intensity. The secondary outcomes were the sensory and affective dimensions of pain; pain unpleasantness; pain catastrophizing; anxiety and depression; sleep quality; fibromyalgia impact; and quality of life. RESULTS: Hypnosis significantly reduced pain scores both at post-intervention and follow-up in comparison with baseline. The analgesic effect of hypnosis combined with pharmacological treatment lasted for at least 3 months and was superior to analgesia promoted by first- and second-line pharmacological treatment alone. Hypnosis significantly improved all parameters evaluated as secondary outcomes both at post-intervention and follow-up without inducing adverse events. CONCLUSION: Our results corroborate that clinical hypnosis is an effective and feasible tool for managing chronic pain and other symptoms of fibromyalgia.

RESUMEN

Introducción: En Santa Clara se recibieron los primeros casos diagnosticados en Cuba de la COVID-19. A partir de alteraciones emocionales reportadas se decidió utilizar la psicoterapia cognitivo conductual como recurso terapéutico para tratar los estados depresivos consecuentes. Objetivo: Evaluar la efectividad de la psicoterapia cognitivo conductual bajo estado hipnótico en pacientes con depresión post-COVID-19. Métodos: Se realizó un estudio explicativo con enfoque cuantitativo. La muestra se seleccionó de manera aleatoria en 30 pacientes divididos en 2 grupos, ingresados entre abril y septiembre del 2020 y diagnosticados con la COVID-19. Se empleó el inventario de depresión de Beck para evaluar el estado depresivo antes y después de la intervención con psicoterapia en estado de vigilia y en hipnosis. Resultados: En ambos grupos, los síntomas depresivos desaparecieron, en el 97 % de los pacientes el estado depresivo se eliminó. La psicoterapia de enfoque cognitivo conductual en estado de vigila e hipnótico se consideró efectiva en la depresión post-COVID-19 a partir de evaluar mejoría en más del 50 % de los casos. El grupo que recibió la psicoterapia en estado hipnótico necesitó la mitad de las sesiones que el grupo en vigilia. Conclusiones: La terapia cognitivo conductual en estado hipnótico es efectiva, reduce las distorsiones cognitivas, los niveles de depresión y la sintomatología depresiva.

Introduction: The first cases diagnosed in Cuba of COVID-19 were received in Santa Clara. Based on reported emotional disturbances, it was decided to use Cognitive Behavioral psychotherapy as a therapeutic resource to treat consequent depressive states. Objective: To evaluate the effectiveness of Cognitive Behavioral psychotherapy under hypnosis in patients with post-COVID-19 depression. Methods: An explanatory study with a quantitative approach was carried out. The sample was randomly selected in 30 patients divided into 2 groups, admitted between April and September 2020 and diagnosed with COVID-19. The Beck Depression Inventory was used to assess depressive state before and after the intervention with psychotherapy in the waking state and in hypnosis. Results: In both groups, the depressive symptoms disappeared, in 97% of the patients the depressive state was eliminated. Psychotherapy with a Cognitive Behavioral approach in a vigilant and hypnotic state was considered effective in post-COVID-19 depression after evaluating improvement in more than 50% of cases. The group that received psychotherapy in a hypnotic state required half as many sessions as the waking group. Conclusions: Cognitive behavioral therapy in a hypnotic state is effective, reducing cognitive distortions, levels of depression and depressive symptoms.

RESUMEN

Introducción: La enuresis nocturna es un motivo frecuente de consulta en pediatría, psiquiatría infantil, psicología y medicina familiar, con mayor porcentaje en los niños de 5 años de edad, seguidos por los de 7 y 9, en ese orden. Objetivo: Determinar la validez de constructo del algoritmo hipnoterapéutico para pacientes con enuresis nocturna monosintomática. Métodos: Se realizó una investigación compleja de 97 pacientes, atendidos en la Clínica de Hipnosis Terapéutica de la Universidad de Ciencias Médicas de Santiago de Cuba, desde febrero del 2021 hasta julio del 2022, la cual estuvo estructurada en 3 etapas metodológicas de validación de constructo para dar continuidad a la etapa IV de la validación de contenido del algoritmo hipnoterapéutico, sobre la base de 2 cuasi-experimentos sin grupo de control y un estudio cuasiexperimental con grupo de control no equivalente de la segunda etapa de dicha investigación. Resultados: El análisis factorial sobre el estudio de componentes principales fue factible, pues los factores 1, 2 y 3 debían mantenerse, lo cual se expresó en el gráfico de sedimentación y en la varianza total explicada, a través de los porcentajes acumulados en los autovalores iniciales y la suma de las saturaciones al cuadrado de la extracción y la rotación con 64,24 %. Conclusiones: La validación de constructo del algoritmo diseñado mostró pertinencia, dada por la idoneidad del análisis factorial y la prueba de esfericidad de Bartlett.

Introduction: Bedwetting is a frequent reason to visit pediatric, infant psychiatry, psychology and family medicine services, with more percentage in 5 years children, followed by 7 and 9 years children, in that order. Objective: To determine the construct validity of the hypnotherapeutic algorithm for patients with monosymptomatic bedwetting. Methods: A complex investigation of 97 patients was carried out, who were assisted in the Therapeutic Hypnosis Clinic of the University of Medical Sciences in Santiago de Cuba, from February, 2021, to July, 2022 which was structured in 3 methodological phases of construct validation to continue the phase IV of hypnotherapeutic algorithm content validation, on the base of 2 quasi-experiments without control group and a quasi-experiment with non equivalent control group of the second phase of this investigation. Results: The factorial analysis on the study of main components was possible, because the factors 1, 2 and 3 should stay, which was expressed in the sedimentation graph and in the explained total variance, through the percentages accumulated in the initial auto values and the sum of saturations to the square of extraction and rotation with 64.24%. Conclusions: The construct validation of the designed algorithm showed relevancy, given by the suitability of the factorial analysis and the Bartlett test of spherical form.

RESUMEN

Anxiety/pain is a combined experience that can hinder dental treatment in children and lead to the development of negative behaviours in any form of surgical treatment. Hypnosis is a suitable option with which to reduce anxiety and pain during dental treatment. In this study, we aimed to evaluate the efficacy of hypnosis compared to the tell/show/do technique for the reduction of anxiety and pain as measured by Face, Legs, Activity, Crying, Consolability (FLACC) scale in children undergoing pulpotomies. We performed a randomized and controlled clinical trial involving 60 children aged 5 to 7 years without previous dental experiences but with clinical and radiographic indications for pulpotomy in the primary mandibular right or left first or second molar. The children were divided into two groups: a control group (treated by conventional behaviour management techniques) and an experimental group (treated by hypnosis). The FLACC scale was used to evaluate anxiety/pain during preoperative, transoperative and postoperative pulpotomy treatment; we also analysed variations in heart rate and skin conductance. The trial was registered at ClinicalTrials.gov (NCT03739346). Statistical analysis was performed in R Studio version 1.2.1335. The FLACC scale was significantly lower in the experimental group (p = 0.022) throughout the entire treatment duration. In addition, heart rate and global skin conductance were both significantly lower in the experimental group when measured at different times (p = 0.005 and p = 0.032, respectively). When compared to conventional behavioural management techniques, the FLACC scale demonstrated that hypnosis was associated with significant reductions in heart rate, skin conductance and anxiety/pain throughout the entire duration of treatment. decreases anxiety/pain during the entire operative procedure. There was clear improvements in anxiety and pain control in patients receiving hypnotic therapy.

RESUMEN

OBJECTIVE: During hypnosis, significant changes in the BOLD signal associated with the anterior default mode network (DMN) and prefrontal attentional systems have been reported as evidence of dissociation defined since Charcot. However, it remains uncertain whether these changes are mainly attributable to the hypnotic state per se or to the target suggestions used to verify subject's state during neuroimaging studies. The aim of the present study is to evidence the brain in hypnosis, contrasting the common resting state versus neutral hypnosis (hypnosis in the absence of target suggestions). METHODS: Twenty-four healthy right-handed volunteers (age 28.3 y.o., 12 females) rated moderate hypnotic responsiveness underwent resting state fMRI at 3.0 T in two sessions, once in neutral hypnosis and the other in the common resting state. Each subject's functional data were analyzed for low-frequency BOLD signal correlations seed-to-voxel for the whole brain in the first-level analysis, and seed-to-voxel in a second-level analysis to estimate group results using seeds for five resting state networks: the default mode (DMN), the central executive (CEN), the salience (SaN), the dorso-lateral attention (DAN), and the sensorimotor (SMN) networks. RESULTS: In general, all network maps of the hypnotic condition presented higher connectivity than those of the resting condition. However, only contrasts for the DAN, SaN, and SMN were statistically significant, including correlated out-of-the-network regions. CONCLUSION: Parietal and occipital regions displayed increased connectivity across networks, implying dissociation from the frontal cortices. This is the first fMRI intrinsic study of hypnosis without target suggestion.

RESUMEN

Recent studies have begun to understand sleep not only as a whole-brain process but also as a complex local phenomenon controlled by specific neurotransmitters that act in different neural networks, which is called "local sleep". Moreover, the basic states of human consciousness-wakefulness, sleep onset (N1), light sleep (N2), deep sleep (N3), and rapid eye movement (REM) sleep-can concurrently appear, which may result in different sleep-related dissociative states. In this article, we classify these sleep-related dissociative states into physiological, pathological, and altered states of consciousness. Physiological states are daydreaming, lucid dreaming, and false awakenings. Pathological states include sleep paralysis, sleepwalking, and REM sleep behavior disorder. Altered states are hypnosis, anesthesia, and psychedelics. We review the neurophysiology and phenomenology of these sleep-related dissociative states of consciousness and update them with recent studies. We conclude that these sleep-related dissociative states have a significant basic and clinical impact since their study contributes to the understanding of consciousness and the proper treatment of neuropsychiatric diseases.

RESUMEN

Introducción: Se conocen diversos tratamientos para tratar y curar la depresión. Entre los más utilizados se encuentran la psicoterapia y la medicación. La hipnosis clínica utiliza un discurso basado en la sugestión y en los reflejos condicionados del sueño, para lograr la estabilidad en la desregulación del ciclo sueño / vigilia, lo cual es un factor esencial en el tratamiento de las personas deprimidas por la COVID-19. Objetivo: Comparar la evolución en la calidad y cantidad de sueño en pacientes con depresión post-COVID que fueron tratados con medicación e hipnosis. Métodos: Se realizó un estudio explicativo-comparativo, y un diseño cuasi-experimental. La muestra fue de 40 pacientes que fueron ingresados en el Hospital Universitario Clínico Quirúrgico «Cmdte. Manuel Fajardo Rivero», de Santa Clara, entre enero y marzo de 2021, con COVID-19. En un grupo de pacientes se empleó el inventario de depresión de Beck y un cuestionario para evaluar la cantidad y calidad del sueño antes y después de la intervención con medicación; en el otro grupo se empleó la hipnosis. Se utilizó la estadística descriptiva. Resultados: En ambos grupos la terapia empleada fue efectiva, redujo los niveles de depresión y eliminó las alteraciones del sueño. Conclusiones: Ambas formas de tratamiento se pueden emplear para tratar la depresión y los desórdenes propios del sueño. El método sugestivo de despertar de sueño hipnótico a sueño natural fue tan efectivo como los psicofármacos empleados.

Introduction: various treatments are known to treat and cure depression. Psychotherapy and medication are among the most used. Clinical hypnosis uses a discourse based on suggestions and conditioned sleep reflexes to achieve stability in sleep-wake cycle dysregulation, which is an essential factor in the treatment of people depressed by COVID-19. Objective: to compare the evolution in sleep quality and quantity in patients with post-COVID depression who were treated with medication and hypnotherapy. Methods: an explanatory comparative study with a quasi-experimental design was carried out. The sample consisted of 40 patients who were admitted due to COVID-19 at "Cmdte. Manuel Fajardo Rivero" Clinical and Surgical University Hospital from Santa Clara between January and March 2021. Beck Depression Inventory and a questionnaire were used in a group of patients to assess the sleep quality and quantity before and after the intervention with medication; hypnosis was used in the other group. Descriptive statistics was also used. Results: the used therapy was effective in both groups, reduced levels of depression and eliminated sleep disturbances. Conclusions: both forms of treatment can be used to treat depression and sleep disorders. The suggestive method of awakening from hypnotic sleep to natural sleep was as effective as the psychoactive drugs used.

RESUMEN

Objective: We compare the effect of HAS, a-tDCS on the left dorsolateral prefrontal cortex (l-DLPFC), and rest-testing on pain measures [(cold pressor test (CPT) (primary outcome) and heat pain threshold]. We also compare their effects on the motor evoked potential (MEP) (primary outcome), short intracortical inhibition (SICI), intracortical facilitation (ICF), and cortical silent period (CSP). Methods: This randomized, blind, crossover trial included 18 women with fibromyalgia, aged from 18 to 65 years old. They received at random and in a crossover order a-tDCS over the l-DLPFC (2mA), HAS, or a rest-testing. Results: HAS compared to a-tDCS increased the pain tolerance with a moderate effect size (ES) [Cohen's f=-0.78; (CI 95%; -1.48 to -0.12)]. While compared to rest-testing, HAS increased the CPT with a large ES [Cohen's f=-0.87; (CI 95%; -1.84 to -0.09)]. The a-tDCS compared to HAS increased the MEP amplitude with large ES [Cohen's f=-1.73 (CI 95%; -2.17 to -0.17)]. Likewise, its ES compared to rest-testing in the MEP size was large [Cohen's f=-1.03; (CI 95%; -2.06 to -0.08)]. Conclusion: These findings revealed that HAS affects contra-regulating mechanisms involved in perception and pain tolerance, while the a-tDCS increased the excitability of the corticospinal pathways. They give a subsidy to investigate their effect as approaches to counter regulate the maladaptive neuroplasticity involved in fibromyalgia.

RESUMEN

BACKGROUND: Patients with chronic low back pain (CLBP) suffer with functional, social, and psychological aspects. There is a growing number of studies with multimodal approaches in the management of these patients, combining physical and behavioral therapies such as osteopathic manipulative treatment, associating pain education and clinical hypnosis. The aim of the present study will be to evaluate the effects of osteopathic manipulative treatment (OMT) associated with pain neuroscience education (PNE) and clinical hypnosis (CH) on pain and disability in participants with CLBP compared to PNE, CH, and sham therapy. METHODS: A randomized controlled clinical trial will be conducted in participants aged 20-60 years with CLBP who will be divided into two groups. Group 1 will receive PNE and CH associated with OMT, and G2 will receive PNE, CH, and sham therapy. In both groups, 4 interventions of a maximum of 50 min and with an interval of 7 days will be performed. As primary outcomes, pain (numerical pain scale), pressure pain threshold (pressure algometer), and disability (Oswestry Disability Questionnaire) will be evaluated and, as a secondary outcome, global impression of improvement (Percent of Improvement Scale), central sensitization (Central Sensitization Questionnaire), biopsychosocial aspects (Start Beck Toll Questionnaire), and behavior of the autonomic nervous system (heart rate variability) will be assessed. Participants will be evaluated in the pre-intervention moments, immediately after the end of the protocol and 4 weeks after the procedures. Randomization will be created through a simple randomized sequence and the evaluator will be blinded to the allocation of intervention groups. DISCUSSION: The guidelines have been encouraging multimodal, biopsychosocial approaches for patients with CLBP; in this sense, the results of this study can help clinicians and researchers in the implementation of a model of treatment strategy for these patients. In addition, patients may benefit from approaches with minimal risk of deleterious effects and low cost. In addition, it will enable the addition of relevant elements to the literature, with approaches that interact and do not segment the body and brain of patients with CLBP, allowing new studies in this scenario. TRIALS REGISTRATION: Date: September 4, 2021/Number: NCT05042115 .

RESUMEN

ABSTRACT BACKGROUND AND OBJECTIVES: Hypnotic suggestions for hypoalgesia or analgesia are efficient for relieving different pain conditions, presenting few or no side effects. However, little is known about its direct effect on the modulation of peripheral nociception. The goal of this study was to evaluate the mechanical and thermal response after specific hypnotic suggestions in healthy volunteers. METHODS: This is a randomized double-blinded controlled trial that aimed to evaluate both mechanical and thermal nociception after specific hypnotic suggestions in healthy volunteers. For this, twenty-seven participants were enrolled, according to the following eligibility criteria: age between 18-65 years and absence of pain complaints or psychological disorders. After signed Free Informed Consent Term (FICT) the participants were divided by a computer-generated randomization in three groups: sham group (no induction of hypnosis), hypnosis-induced pain group and hypnosis-induced analgesia group. Susceptibility to hypnosis was assessed through the Waterloo-Stanford Group C (WSGC) scale of hypnotic susceptibility and outcomes included evaluation of questionnaires (Hospital Anxiety and Depression Scale and Short Form Brief Pain Inventory) as well as the examination of mechanical and thermal nociception through the Quantitative Sensory Testing (QST), a tool widely used to investigate somatosensory sensitivity by assessing functions of small A-δ and C nerve sensory fibers, before and after specific hypnotic suggestion for pain and analgesia made by a qualified hypnotherapist. RESULTS: Data demonstrated that specific hypnotic suggestions induced significant changes in mechanical and thermal sensitivity. The pain group revealed an increase in mechanical hyperalgesia and allodynia, while the analgesia group increased pain thresholds to thermal stimulations, being conditioned to withstand temperature changes after hypnosis, demonstrating a modulatory effect for both pain and analgesia sensations in healthy volunteers. CONCLUSION: The evidence presented in this study supports the use of the hypnosis technique as an auxiliary tool in clinical practice. HIGHLIGHTS Specific hypnotic suggestions can modulate peripheral nociception in healthy subjects. Data show a modulatory effect for both pain and analgesia sensations. Hypnosis can be considered a feasible technique for the clinical pain management.

RESUMO JUSTIFICATIVA E OBJETIVOS: Sugestões hipnóticas de hipoalgesia ou analgesia são eficientes para aliviar diferentes quadros álgicos, apresentando poucos ou nenhum efeito colateral. No entanto, pouco se sabe sobre seu efeito direto na modulação da nocicepção periférica. O objetivo deste estudo foi avaliar a resposta mecânica e térmica após sugestões hipnóticas específicas em voluntários saudáveis. MÉTODOS: Este é um estudo randomizado e duplo-cego que visou avaliar a nocicepção mecânica e térmica após sugestões hipnóticas específicas em voluntários saudáveis. Para isso, vinte e sete participantes foram selecionados, de acordo com os seguintes critérios de elegibilidade: idade entre 18 e 65 anos e ausência de distúrbios psicológicos e de queixas de dor. Após a assinatura do Termo de Consentimento Livre e Esclarecido (TCLE), os participantes foram divididos por randomização gerada por computador em três grupos: grupo sham (sem indução de hipnose), grupo dor induzida por hipnose e grupo analgesia induzida por hipnose. A suscetibilidade à hipnose foi avaliada através da escala Waterloo-Stanford Group C (WSGC) de suscetibilidade hipnótica e os resultados incluíram a avaliação de questionários (Escala Hospitalar de Ansiedade e Depressão e Inventário Breve de Dor), bem como o exame de nocicepção mecânica e térmica através do Teste Sensorial Quantitativo (QST), uma ferramenta amplamente utilizada para investigar a sensibilidade somatossensorial por meio da avaliação das funções das fibras sensoriais finas dos nervos A-δ e C, antes e após sugestão hipnótica específica para dor e analgesia aplicada por um hipnoterapeuta qualificado. RESULTADOS: Os dados mostraram que as sugestões hipnóticas específicas induziram mudanças significativas na sensibilidade mecânica e térmica dos indivíduos. O grupo dor revelou aumento da hiperalgesia mecânica e da alodinia, enquanto o grupo analgesia aumentou os limiares de dor por estímulos térmicos, sendo condicionado a suportar mudanças de temperatura após a hipnose, demonstrando efeito modulador tanto para as sensações de dor quanto de analgesia em voluntários saudáveis. CONCLUSÃO: As evidências apresentadas neste estudo sustentam o uso da técnica de hipnose como ferramenta auxiliar na prática clínica. DESTAQUES Sugestões hipnóticas específicas podem modular a nocicepção periférica em sujeitos saudáveis. Os dados mostram um efeito modulador tanto para as sensações de dor quanto de analgesia. A hipnose pode ser considerada uma técnica viável para o manejo clínico da dor.

RESUMEN

Background: Improving anesthesia administration for elderly population is of particular importance because they undergo considerably more surgical procedures and are at the most risk of suffering from anesthesia-related complications. Intraoperative brain monitors electroencephalogram (EEG) have proved useful in the general population, however, in elderly subjects this is contentious. Probably because these monitors do not account for the natural differences in EEG signals between young and older patients. In this study we attempted to systematically characterize the age-dependence of different EEG measures of anesthesia hypnosis. Methods: We recorded EEG from 30 patients with a wide age range (19-99 years old) and analyzed four different proposed indexes of depth of hypnosis before, during and after loss of behavioral response due to slow propofol infusion during anesthetic induction. We analyzed Bispectral Index (BIS), Alpha Power and two entropy-related EEG measures, Lempel-Ziv complexity (LZc), and permutation entropy (PE) using mixed-effect analysis of variances (ANOVAs). We evaluated their possible age biases and their trajectories during propofol induction. Results: All measures were dependent on anesthesia stages. BIS, LZc, and PE presented lower values at increasing anesthetic dosage. Inversely, Alpha Power increased with increasing propofol at low doses, however this relation was reversed at greater effect-site propofol concentrations. Significant group differences between elderly patients (>65 years) and young patients were observed for BIS, Alpha Power, and LZc, but not for PE. Conclusion: BIS, Alpha Power, and LZc show important age-related biases during slow propofol induction. These should be considered when interpreting and designing EEG monitors for clinical settings. Interestingly, PE did not present significant age differences, which makes it a promising candidate as an age-independent measure of hypnotic depth to be used in future monitor development.

RESUMEN

Introducción: En los últimos años la anestesia libre de opioides ha constituido una alternativa más a las técnicas tradicionales de anestesia general. Con la exclusión de este grupo de fármacos se evitan los múltiples efectos adversos y complicaciones asociados al mismo. A pesar de que la anestesia libre de opioides tiene sus indicaciones y que ha demostrado sus beneficios en cierto grupo de pacientes, existen aún controversias en relación con su utilidad en el paciente obeso. Características como la obesidad hacen que los modelos multimodales empleados para programar la anestesia libre de opioides sean cada vez más complejos. Objetivos: Describir un caso clínico realizado con la técnica de anestesia libre de opioides que constituye la primera experiencia en Ecuador. Presentación del caso: Se presenta el caso de una paciente obesa intervenida de colecistectomía laparoscópica mediante infusión de propofol, ketamina, lidocaína, sulfato de magnesio, y dexmedetomidina. La titulación de estos fármacos se realizó mediante cálculo de concentraciones plasmáticas a través de modelos farmacocinéticos y guiada por monitorización de profundidad anestésica y analgésica, con lo cual se logró optimizar el consumo de fármacos, disminuir las complicaciones y una evolución clínica favorable. Hasta donde se conoce a nivel local y de país (Ecuador) es la primera experiencia que se reporta con esta técnica. Conclusiones: La anestesia libre de opioides puede resultar una elección en el paciente obeso ya que asegura una adecuada recuperación sin efectos adversos asociados(AU)

Introduction: In recent years, opioid-free anesthesia has become another alternative in front of traditional general anesthesia techniques. The exclusion of this group of drugs avoids the numerous adverse effects and complications associated with its usage. Although opioid-free anesthesia has its indications and has showed its benefits in a certain group of patients, there is still controversy regarding its usefulness in the obese patient. Characteristics such as obesity make the multimodal models used to program opioid-free anesthesia increasingly complex. Objectives: To describe a clinical case involving the opioid-free anesthesia technique, which is the first experience in Ecuador. Case presentation: The case is presented of a female obese patient who underwent laparoscopic cholecystectomy by infusion of propofol, ketamine, lidocaine, magnesium sulfate and dexmedetomidine. Titration of these drugs was carried out by calculating plasma concentrations through pharmacokinetic models and guided by monitoring of anesthetic and analgesic depth, thus optimizing drug consumption, reducing complications and achieving a favorable clinical evolution. As far as known locally and in the country (Ecuador), this is the first reported experience with this technique. Conclusions: Opioid-free anesthesia may be a choice in the obese patient, since it ensures adequate recovery without associated adverse effects(AU)

RESUMEN

Hypnosis presents an auxiliary adjunct in medical, dental, physiotherapeutic, and other clinical fields. This narrative review verified the effect of hypnosis in the control of pain and anxiety in dentistry. It presents the importance and effectiveness of hypnosis to aid dental procedures. It´s use in dentistry allows a wide range of applications such as sedation, analgesia, anesthesia, and hemostasis to facilitate treatment and improve the experience of dental care for dental patients. A discussion about the regulation of hypnosis in dentistry in Brazil, the attributions of dentists qualified in hypnosis, as well as the benefits of application based on evidence of hypnosis in dentistry, and the need for certification by hypnosis practitioners due to the possible risks inherent to the use of hypnosis are presented. Hypnosis is useful in the management of pain and anxiety in dentistry, when the dental practitioner is adequately experienced in this modality and the patients are carefully selected.

RESUMEN

Resumo Este trabalho busca desenvolver uma aproximação entre o pensamento de Milton Erickson (1901-1980) e Charles Peirce (1839-1914), focalizando as noções de singularidade e falibilismo, com o objetivo de demonstrar as semelhanças existentes, o papel que desempenham em suas obras, como se relacionam e as implicações teóricas que geram para a hipnose. Descreve-se brevemente como o contexto histórico de cada um influenciou suas concepções iniciais. Em seguida, discute-se o modo como o falibilismo presente na concepção de semiose considera a singularidade dos fenômenos existentes e viabiliza o sinequismo, bem como os processos de evolução constante por meio de mudança de hábitos. Este estudo desenvolve a observação de Erickson sobre o sujeito enquanto signo representante de experiências de vida e relaciona as implicações teóricas do conceito de mente como semiose em torno do processo constitutivo de fenômenos acessíveis em experiência de transe.

Abstract This paper attempts a theoretical rapprochement between Milton Erickson's (1901-1980) and Charles Peirce's (1839-1914) thought, focusing on the concepts of singularity and fallibilism to point out their similarities, the role they play on their works, how they relate to each other, and their theoretical implications regarding hypnosis. First, the text briefly describes both authors' historical background and its influence over their early conceptions. Then, it discusses how fallibilism, present in the concept of semiosis, considers the singularity of existing phenomena and enables synechism, as well as the processes of constant evolution through change of habits. This study develops Erickson's observation about the subject as a representative sign of life experiences and relates, initially, the theoretical implications of mind-as-semiosis concerning the constitutive process of phenomena accessible in trance experience.

Résumé Cet article tente un rapprochement entre la pensée de Milton Erickson (1901-1980) et celle de Charles Peirce (1839-1914), en se concentrant sur les concepts de singularité et de faillibilisme afin de mettre en évidence leurs similitudes, le rôle qu'ils jouent dans leurs œuvres, la façon dont ils se rapportent l'un à l'autre, et leurs implications théoriques concernant l'hypnose. Tout d'abord, le texte décrit brièvement le contexte historique des deux auteurs et son influence sur leurs premières conceptions. Ensuite, il aborde la manière dont le faillibilisme, présent dans le concept de sémiose, considère la singularité des phénomènes existants et permet le sinéquisme, ainsi que les processus d'évolution constante par le changement d'habitudes. Cette étude développe l'observation d'Erickson sur le sujet comme signe représentatif des expériences de vie et relate, dans un premier temps, les implications théoriques de l'esprit comme sémiose concernant le processus constitutif des phénomènes accessibles dans l'expérience de transe.

RESUMEN

ABSTRACT BACKGROUND AND OBJECTIVES: Pain has great impact on public health and presents a social cost which transcends the financial aspect. Hypnosis is a focal, quick and low-cost resource with effective change possibilities in pain management. The objective of this study was to identify evidence of the efficiency of hypnosis in pain management. CONTENTS: This study consists of a systematic literature review held in February 2020. Search was carried out in the Pubmed, Cochrane, LILACS, Scielo and PsycInfo platforms, using the keywords "clinical trials", "hypnosis", "pain management", "pain intensity", and "quality of life", totalizing 18 studies after peer review. Most articles are randomized, controlled by comparing hypnosis to standard treatment or other integrative practices, and focus mainly on the aspects of intensity, quality and interference of pain as an outcome variable. Six studies mention quality of life and only two refer catastrophization as an important intervening variable. CONCLUSION: Hypnosis is an effective technique for pain management, considering that there was an improvement in pain management with the improvement of at least one aspect, be it intensity, interference or quality of pain. However, it's necessary to highlight important limitations of the studies, such as the small sample size and the complexity of systematizing subjective techniques, which highlights the need for more clinical trials, including multicentric studies, so that larger samples can be obtained.

RESUMO JUSTIFICATIVA E OBJETIVOS: A dor tem um amplo impacto na saúde pública, apresentando um custo social que extrapola o financeiro. A hipnose mostra-se como recurso focal, breve e de baixo custo, com possibilidades efetivas de mudança no manejo da dor. O objetivo deste estudo foi verificar a eficácia da hipnose no manejo da dor não procedimental. CONTEÚDO: Trata-se de uma revisão sistemática da literatura realizada em fevereiro de 2020. As buscas foram realizadas nas plataformas Pubmed, Cochrane, LILACS, Scielo e PsycInfo, utilizando-se os descritores "ensaio clínico", "hipnose", "manejo de dor", "intensidade de dor" e "qualidade de vida", totalizando 18 estudos após a avaliação de pares. A maioria dos estudos era randomizada, controlada por comparação da hipnose com tratamento padrão ou outra prática integrativa e centrava-se principalmente nos aspectos de intensidade, qualidade e interferência da dor como variável desfecho. Seis estudos fazem menção à qualidade de vida e apenas dois se referem à catastrofização como variável interveniente importante. CONCLUSÃO: A hipnose é uma técnica eficaz no manejo da dor, considerando que houve melhora no manejo da dor a partir da melhora em, pelo menos, um aspecto, seja intensidade, interferência ou qualidade da dor. No entanto, é preciso ressaltar importantes limitações dos estudos, como o tamanho reduzido das amostras e a complexidade de sistematização das técnicas subjetivas, o que evidencia a necessidade de mais ensaios clínicos, inclusive multicêntricos, de modo a garantir amostras maiores.

RESUMEN

RESUMEN Introducción: la depresión es uno de los problemas de salud que más afecta a los seres humanos a nivel mundial. En Cuba, un elevado número de personas padece este flagelo, sin distinción de razas, sexos u otras categorías. Objetivo: evaluar la efectividad de la hipnosis como modalidad terapéutica en pacientes deprimidos. Materiales y métodos: se realizó un estudio explicativo de tipo experimental de comparación de grupo pre-post prueba en 30 pacientes con trastornos depresivos; 15 de ellos se atendieron con hipnoterapia (grupo estudio) y otros 15 mediante terapia racional emotiva conductual (grupo control). Por la importancia para enriquecer la investigación, se definió como variable independiente el tratamiento empleado según el grupo, y como variables dependientes la respuesta psicológica antidepresiva y ansiolítica. Los datos se procesaron cuantitativa y cualitativamente. Se empleó la prueba de las probabilidades exactas de Fisher y la t de Student para validar la significación del cambio. Resultados: en términos de evolución clínica, la hipnoterapia fue efectiva, ya que el 93,3 % de los pacientes mejoraron significativamente en comparación con los resultados obtenidos con la terapia conductual racional emotiva, dados en un 73,33 %. Conclusión: la hipnoterapia es tan efectiva como la terapia racional emotiva conductual, y si bien no hubo diferencias significativas por los resultados del estadígrafo matemático empleado, sí las hubo desde el punto de vista práctico y clínico, pues evolucionaron más rápido los pacientes del grupo estudio que los del grupo control (AU).

ABSTRACT Introduction: depression is one of the health problems more affecting the human being around the world. A high number of persons suffers this scourge, without distinction of race, sex or any other category. Objective: to assess hypnosis effectiveness as a therapeutic modality in depressed patients. Materials and methods: an experimental-kind explanatory study was carried out comparing a group of 30 patients with depressive disorders before and after test; 15 of them were treated with hypnotherapy (study group) and 15 with rational emotive behavioral therapy (control group). For the importance of enriching the research the treatment used according to each group was defined as independent variable and the anxiolytic and anti-depressive psychological answer. Data were quantitative and qualitatively processed. Fisher's exact test and T student test were used to validate the change significance. Results: in terms of clinical evolution, hypnotherapy was effective, since 93.3% of patients significantly improved in comparison to the results achieved with the rational emotive behavioral therapy, reaching 73.33%. Conclusions: hypnotherapy is as effective as rational emotive behavioral therapy, and although there were not significant differences due to the results of the used mathematical statistic, there they were from the practical and clinical point of view, because the patients from the study group improved faster than the ones in the control group AU).
