This study will measure the efficacy of hypnosis on pain after a major abdominal surgery. The aim is to further improve comfort and rehabilitation of patients after surgery, beyond the usual early recovery after surgery (ERAS) enhancement protocols. Patients will be randomised (1:2) to the standard of care regarding pain management and rehabilitation, as part of the ERAS protocol, vs. ERAS + an additional hypnosis intervention. In this group, hospitalised patients are given 3 hypnosis sessions targeting analgesia between postoperative day 1 to 12. The study will collect outcomes about pain and its burden, sleep quality, appetite, mobilisation and mood. Secondary outcomes also include use of pain medication and length of hospital stay.
The investigators propose to evaluate the analgesic effect of medical hypnosis prior to the pharmacological induction of general anesthesia versus a classical pharmacological induction of anesthesia. Monitoring of the NOL index (Nociception index) as well as all the other classical parameters under general anesthesia (heart rate, blood pressure etc) will allow evaluation of the level of nociception related to oro-tracheal intubation as well as the one related to standardized electrical tetanic stimulation during general anesthesia and before surgical incision, between the two groups. The investigators know from the literature that the use of medical hypnosis in combination with anesthetic drugs allows for a significant reduction of hypnotic and opioid drugs. The investigators aim here at evaluating the real and objective impact of pre-anesthesia hypnosis on intraoperative nociception by using the NOL index which has been developed and used recently to better detect nociceptive stimuli under anesthesia. This clinical trial will provide an objective answer on the analgesic properties of intraoperative hypnosis. If this is confirmed, hypnosis could find its place in the management of perioperative nociception around general anesthesia.
Many clinical trials assessing the effectiveness of hypnosis have been conducted in recent years, some of which show that hypnosis reduces pain perception better than drug treatments administered to control groups, and that it is at least as effective as other complementary therapies (such as massage, acupuncture, yoga). However, their conclusions are limited by a significant risk of bias, and further studies with rigorous methodology remain necessary. The hypothesis of this study is that hypnosis support methods can reduce anxiety in patients requiring facial surgery under local anaesthesia, and thus improve their medical management. The purpose of this study is to evaluate the effectiveness of hypnosis support on the patient's state of anxiety before and after outpatient surgery under local anaesthesia in the Maxillofacial Surgery Department.
Virtual reality has been used for acute pain management (burn patients) with positive results. Hypnosis has known beneficial effects on patients in the peri-operative setting. The investigators are combining both by giving a virtual reality hypnosis (VRH) session to the patients during a known painful post-operative moment. (physiotherapy) It is the investigator intention to compare pain after physiotherapy during the first 3 days after a total knee arthroplasty, between 2 groups. One group , the VR group gets standard treatment with VRH and the second, the sham group, gets standard treatment with a sham VR session.
The investigation will assess the brain activation connectivity patterns associated with hypnosis and possible hypnotic sub-states by means of functional magnetic resonance imaging (fMRI). For that purpose, 50 healthy participants highly familiar with hypnosis (according to the OMNI-method) will be recruited and tested.
Introduction: Many interventions such as hypnosis, mindfulness meditation, conditioned pain modulation and placebos have been shown to effectively reduce pain both in the laboratory and in clinical settings. However, little is known about their neurophysiological mechanisms of action. Analgesia induced by these techniques is thought to be based on opioidergic and non-opioidergic mechanisms (potentially endocannabinoid mechanisms). Objective: Our main objective is to evaluate the effect of hypnosis, meditation, conditioned pain modulation and placebo on blood concentrations of endocannabinoids (anandamide, 2-arachidonylglycerol, N-palmitoyl-ethanolamine, N-oleoylethanolamide), endogenous opioids (β-endorphins, met / leu-enkephalins, and dynorphins) and norepinephrine in healthy adults. Methods: This study is based on a single-group pre-experimental research design in which two experimental sessions including hypnosis or meditation, conditioned pain modulation and placebo interventions will be completed by all participants. In order to have a better description of the sociodemographic and clinical characteristics of the sample, information will be collected by questionnaires or tests filled by participants at baseline, including: age, sex, language, culture, religion, salary, menstrual cycle of women, medication (if any), mood, anxiety, pain catastrophizing, mindfulness, hypnotic susceptibility, and DNA information. Outcome measures will be collected before, during and after each intervention. The primary outcome is plasma concentrations of endocannabinoids. Secondary measurements include plasma concentrations of endogenous opioids and norepinephrine; change in pain intensity during the thermal noxious stimuli; and autonomic nervous system variability (as measured by heart rate variability). Anticipated results: The investigators expect a positive relationship between the change in pain intensity (analgesia) induced by the interventions (hypnosis, meditation, conditioned pain modulation, and placebo) and the change (increase) in plasma concentrations of endocannabinoids, opioids, and norepinephrine in healthy adults. It is also believed that the interventions will influence heart rate variability. Moreover, it is expected that there will be a relationship between the efficiency of the analgesic intervention and some gene polymorphisms associated to pain modulation and endocannabinoids, opioids or norepinephrine in healthy individuals.
The purpose of the study is to determine if teaching self-hypnosis techniques to patients prior to knee replacement surgery will decrease their pain medication requirements, pain medication side-effects, length of stay in the hospital, readmission rates, pain, anxiety, physical function, satisfaction scores, and cost of admission.
Hypnotic glove anesthesia is a hypnosis technique wherein the patient, following the suggestions of the hypnotherapist, is mentally capable to create a loss of sensation in areas of the hand that would be covered by a glove. We investigated the effects of hypnotic glove anesthesia on skin temperature measured by thermography.
Hypnotic trance and mindfulness meditation have both been shown to have benefits for physical health. The current study seeks to determine if there are distinct patterns of brain activity that correlate with hypnotic trance, mindfulness meditation or both, and to relate these patterns to measurable markers of physical well-being. Precise neuroimaging of heightened attentional states will guide future researchers and practitioners toward more effective techniques of mind/body control.
