Patients Participating in Nasogastric Tube Insertion through Hypnoanalgesia during High-dose Chemotherapy-induced Aplasia.

The insertion of a nasogastric (NG) tube is often a difficult experience for both patients and caregivers. This often results in a high failure rate of NG insertion. This pilot study aimed to evaluate the effectiveness, tolerance, and acceptability of hypnoanalgesia to assist self-insertion of an NG tube. Patients undergoing high-dose chemotherapy for autologous or allogeneic hematopoietic stem cell transplantation (HSCT) or acute leukemia and with high risk of aplasia were included in the study. A total of 38 patients were included during 6 consecutive months. They all achieved successful NG tube self-insertion. The NG tube remained in place during hospitalization in 32 cases for an average duration of 15 days. Six patients rejected the NG tube during vomiting but they all voluntarily attempted it again later on and succeeded. The discomfort related to NG-tube insertion was mild. This pilot study suggests that NG tube self-insertion assisted by hypnoanalgesia may be effective, well-accepted, and well-tolerated in patients. These promising findings will need further confirmation.

Anestesia total intravenosa libre de opioides guiada por qCON y qNOX en paciente obesa / Total Intravenous anesthesia in patients with intestinal occlusive syndrome

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)

Neural functional correlates of hypnosis and hypnoanalgesia: Role of the cingulate cortex.

Hypnosis is a hetero-induced or self-induced altered state of consciousness that involves focused attention and reduced peripheral awareness. It is determined by response to suggestions and can be used in the management of various clinical conditions. Nowadays there is growing attention to the neurobiological correlates of hypnosis because of its future clinical applications. The greater attention is due to the wide range of applications that might stem from its knowledge. Functional neuroimaging studies show that hypnosis affects attention by modulating the activation of the anterior cingulate cortex and other brain areas, modifying the conflict monitoring and cognitive control. During hypnoanalgesia, several changes in brain functions occur in all the areas of the pain network, and other brain areas. Among these, the anterior cingulate cortex is significantly involved in modulating the activity of pain circuits under hypnosis, both in the affective, sensory-cognitive, and behavioral aspects. The study of the functionality of the cingulate cortices, mainly the anterior and medial portions, appears to be crucial for better understanding the hypnotic phenomena, related to both the neurocognitive and somatosensory aspects.

Continuous Flow Synthesis of Propofol.

Herein, we report a continuous flow process for the synthesis of 2,6-diisopropylphenol-also known as Propofol-a short-acting intravenous anesthesia, widely used in intensive care medicine to provide sedation and hypnosis. The synthesis is based on a two-step procedure: a double Friedel-Crafts alkylation followed by a decarboxylation step, both under continuous flow.

[Hypnoanalgesia, role of the nurse-caregiver pair]. / Hypnoanalgésie, rôle du binôme infirmière­aide-soignante.

Hypnosedation for endocavitary uterovaginal applications: A pilot study.

PURPOSE: Implantations for uterovaginal brachytherapy are usually performed under general or spinal anesthesia, which are not without risk. As it is a rather short procedure and since postoperative pain is minimal, hypnosedation was proposed to selected patients requiring endocavitary applications as part of their routine treatment. METHODS AND MATERIALS: Consecutive patients requiring intracavitary uterovaginal brachytherapy from January to October 2019 were included if they accepted the procedure. A premedication was systematically administered. Hypnosedation was based on an Ericksonian technique. The procedure was immediately interrupted if the patient requested it, in cases of extreme anxiety or pain. Procedure was in that case rescheduled with a "classical" anesthesia technique. RESULTS: A total of 20 patients were included. Four patients had to be converted toward a general anesthesia: one because of a fibroma on the probe's way and three young patients with a very anteverted/retroverted uterus that was painful at every mobilization. Mean and maximum pain scores during implant were 2.9/10 and 5.1/10, respectively. The most painful maneuver was cervical dilation for 45% of the patients, followed by mold insertion in 40% of cases. About 85% of the patients declared that hypnosis helped them relax; 90% of the patients would recommend the technique. No procedure-related complication occurred. CONCLUSION: With a 70% success rate (correct implant with mean pain and anxiety scores < 5), one can conclude that uterovaginal brachytherapy implantation under hypnosedation is feasible and received a high satisfaction rate from the patients. This technique may reduce overall treatment time in a context of difficult access to the OR and to anesthesiologists, while reducing anesthetic drugs resort and postoperative nausea.

HYPNOTIZABILITY-RELATED FAAH C385A POLYMORPHISM: POSSIBLE ENDOCANNABINOID CONTRIBUTION TO SUGGESTION-INDUCED ANALGESIA.

Fatty acid amide hydrolase (FAAH) degrades the endogenous endocannabinoid (eCB) anandamide and might be involved in the response to suggestions of analgesia in subjects with high hypnotizability scores (highs). Since the A allele of the FAAH C385A polymorphism (rs324420) is associated with lower FAAH activity, it was studied in 21 highs, 66 low hypnotizable individuals (lows), and 172 individuals not selected for hypnotizability (controls) representing the general population. No significant difference was observed among groups, but the A allele frequency showed a significant trend to increase from lows to controls and from controls to highs. Since eCB small differences can be amplified by eCB interactions with other neurotransmitters, a contribution of the FAAH polymorphism to the highs' analgesia should not be excluded.

MECHANISMS OF HYPNOTIC ANALGESIA EXPLAINED BY FUNCTIONAL MAGNETIC RESONANCE (fMRI).

Hypnotic-focused analgesia (HFA) was produced in 20 highly hypnotizable subjects receiving nociceptive stimulations while undergoing functional magnetic resonance imaging (fMRI). The fMRI pattern in brain cortex activation while receiving a painful stimulus was recorded both during nonhypnosis and during HFA. The scanning protocol included the acquisition of a T1-weighted structural scan, 4 functional scans, a T2-weighted axial scan, and a fluid attenuated inversion recovery (FLAIR) scan. Total imaging time, including localization and structural image acquisitions, was approximately 60 minutes. Without HFA, the subjects reported subjective presence of pain, and the cortex primary sensory areas S1, S2, and S3 were activated. During HFA, the subjects reported complete absence of subjective pain and S1, S2, and S3 were deactivated. The findings suggest that HFA may prevent painful stimuli from reaching the sensory brain cortex, possibly through a gate-control mechanism.

Hypnosis for cingulate-mediated analgesia and disease treatment.

Hypnosis is a technique that induces changes in perceptual experience through response to specific suggestions. By means of functional neuroimaging, a large body of clinical and experimental studies has shown that hypnotic processes modify internal (self-awareness) as well as external (environmental awareness) brain networks. Objective quantifications of this kind permit the characterization of cerebral changes after hypnotic induction and its uses in the clinical setting. Hypnosedation is one such application, as it combines hypnosis with local anesthesia in patients undergoing surgery. The power of this technique lies in the avoidance of general anesthesia and its potential complications that emerge during and after surgery. Hypnosedation is associated with improved intraoperative comfort and reduced perioperative anxiety and pain. It ensures a faster recovery of the patient and diminishes the intraoperative requirements for sedative or analgesic drugs. Mechanisms underlying the modulation of pain perception under hypnotic conditions involve cortical and subcortical areas, mainly the anterior cingulate and prefrontal cortices as well as the basal ganglia and thalami. In that respect, hypnosis-induced analgesia is an effective and highly cost-effective alternative to sedation during surgery and symptom management.

HYPNOTIC GLOVE ANESTHESIA INDUCES SKIN TEMPERATURE CHANGES IN ADULT VOLUNTEERS: A Prospective Controlled Pilot Study.

This study assessed whether a focal glove hypnotic hand anesthesia induced thermal changes within the area of hypnotic protection. Skin temperature of hands, wrists, and forearms was continuously recorded bilaterally using infrared thermography in 30 volunteers. Thermal recordings were obtained prior to, after glove building, and after its withdrawal, with the contralateral upper limb serving as control side. Analgesic glove induced a statistically significant difference in temperature variation within the hand, wrist, and distal forearm on the glove side, compared with proximal forearm and control side. Hypnotic glove analgesia provides significant changes in skin temperature within protected areas. Further research is required to determine the mechanisms of these objective changes induced by hypnosis.

Impact of Perioperative Hypnosedation on Postmastectomy Chronic Pain: Preliminary Results.

Objectives: The main aim of this prospective nonrandomized study was to evaluate if mastectomy performed with perioperative hypnosedation led to a lower incidence of chronic pain compared with mastectomy under general anesthesia. Methods: Forty-two breast cancer patients who underwent mastectomy either under GA (GA group, n = 21) or HYP (HYP group, n = 21) associated with local and/or regional anesthesia were included. The type of adjuvant therapy as well as the number of reconstructive surgical procedures were well balanced between the 2 groups. The average age of the patients and the type of axillary surgery were also equivalent. Incidence of postmastectomy chronic pain, lymphedema, and shoulder range of motion (ROM) were evaluated after a mean 4-year follow-up. Results: The study shows a statistically significant lower incidence of postmastectomy chronic pain in HYP group (1/21, 1 patient out of 21 experiencing pain) compared with GA group (9/21) with 9 patients out of 21 experiencing pain (P = .008). ROM for shoulder was also less frequently affected in the hypnosedation group, as only 1 patient had decreased ROM, instead of 7 in the other group (P = .04). Conclusions: Our study is the first to hint at the potential benefits of hypnosedation on postmastectomy chronic pain. Despite the limitations of this study (nonrandomized, small sample), preliminary results merit further study of hypnosedation.

The Effect of Hypnosis on Intraoperative Hemorrhage and Postoperative Pain in Rhinoplasty.

This prospective, randomized study investigated the effects of preoperative hypnosis on hemorrhage and pain in open septorhinoplasty (SRP). Twenty-two patients undergoing SRP under general anesthesia were included and equally divided into two groups. Patients in the hypnosis group (HG) received a total of three sessions of hypnotic induction. The first two sessions occurred 3 days and 1 day prior to surgery, respectively, and the last session was in the hospital the day of surgery. The other 11 patients constituted the control group (CG). Compared with the CG, the HG's intraoperative use of total remifentanil and the visual analog scale scores at the 2nd and 3rd postoperative hours were significantly lower (p < .05). Hypnosis did not affect the quality of the surgical field. However, preoperative use of hypnosis decreased intraoperative remifentanil requirements and postoperative pain.

Quantitative Sensory Testing (QST) Estimation of Regional Cutaneous Thermal Sensitivity During Waking State, Neutral Hypnosis, and Temperature Specific Suggestions.

This study aimed to determine the effects of neutral hypnosis and hypnotic temperature suggestions in thermal and pain thresholds compared to resting state. Sixteen healthy medium or high hypnotizable volunteers were enrolled. Hypnotizability was assessed with the Hypnotic Induction Profile (HIP); QST was checked in resting state, in neutral hypnosis, after suggestions of heat and cold, and after deinduction. A significant increase in heat threshold was recorded during hypnosis with both cold and heat suggestions compared to neutral hypnosis. HIP induction score showed a linear correlation with changes of temperature thresholds after heat and cold suggestions. Thermal suggestions may result in a significant increase of heat perception thresholds with respect to neutral hypnosis. HIP score is related to thermal threshold changes. QST is a valuable and manageable tool to measure temperature threshold change during hypnosis.

The Laurs of Hypnotic Communication and the "Lived in Imagination" Technique in Medical Practice.

This article describes two common hypnotic communication techniques that can be used in anesthesiology and more generally for a variety of medical applications. First, the LAURS (listening, acceptance, utilization, reframing, suggestion) hypnotic communication structure is detailed. This technique allows clinicians to rapidly build patient rapport and maximize the chance of a suggestion being realized. Second, the "Lived in Imagination" technique can be used to supplement a less than perfect local anesthesia technique or help provide analgesia or sedation to support a patient undergoing minor or even major surgical procedures. These techniques may allow for an adjunctive, seamless integration during standard clinical care.

PRERECORDED HYPNOTIC PERI-SURGICAL INTERVENTION TO ALLEVIATE RISK OF CHRONIC POSTSURGICAL PAIN IN TOTAL KNEE REPLACEMENT: A RANDOMIZED CONTROLLED PILOT STUDY.

This pilot study evaluated the effect sizes associated with prerecorded hypnotic interventions provided during the perisurgical period for reducing risk factors associated with chronic postsurgical pain, including acute postsurgical pain, anxiety, depression, and pain catastrophizing. A total of 25 participants (N = -25) were randomly assigned to receive a hypnotic intervention (n = 8), minimal-effect treatment (n = 8), or treatment as usual (n = 9) during their hospital stay for total knee replacement (TKR). Participants were followed for 6 months after hospital discharge. Results indicate that prerecorded hypnotic intervention exerted medium effects for reducing acute postsurgical pain and large effects for reducing perisurgical anxiety and pain catastrophizing. The findings indicate that a fully powered clinical trial to evaluate the beneficial effects of prerecorded hypnosis to manage pain and psychological distress in patients undergoing TKR is warranted.

Prostate brachytherapy under hypnosedation: A prospective evaluation.

PURPOSE: Hypnosedation (HS) for brachytherapy has been proposed in patients with prostate cancer and has been evaluated. MATERIALS AND METHODS: 79 patients were treated with brachytherapy under HS. The Visual Analog Scale questionnaire was used to assess comfort and anxiety and the lowest, mean, and highest level of pain. Data for 79 patients who underwent general anesthesia (GA) and 37 patients who underwent spinal anesthesia (SA) treated at the same period were compared with HS group in terms of medication and treatment duration. RESULTS: 11 patients (13.9%) requested a GA, because they did not reach the hypnotic level. For the remaining 68 patients, the mean pain and comfort scores evaluated just after the intervention were 3.1 and 7.4, respectively. At 8 weeks, the scores were 2.8 and 7.5, respectively. 66 patients (97%) would choose this approach again and recommend it to other patients. The patients in the HS group received significant less medications than in the GA (remifentanil, propofol, kétamine, phenylephrine, ephedrine…) or SA (sufentanil, midazolam, morphine, bupivacaine…) groups with mean values of 3.1 vs. 7.9 vs. 5.6 (p < 0.0001), respectively. HS increased the mean time of surgery room occupation by 12 min vs. GA and by 20 min vs. SA. However, the recovery room occupation is avoided with HS (GA = 61 min and SA = 67 min) and a shorter duration of a need for a urinary catheter was noted. CONCLUSIONS: HS is a feasible and comfortable method of anesthesia and a good alternative to GA and SA for patients undergoing prostate brachytherapy, with reduced treatment duration and number of medications.

[Making the patient an actor in the insertion of a nasogastric tube through hypnoanalgesia]. / Rendre le patient acteur de la pose d'une sonde naso-gastrique grâce à l'hypnoanalgésie.

The use of a nasogastric tube can prevent certain complications in patients treated for malignant hematopathy. But this treatment is often experienced as a traumatic act by patients and sometimes even by caregivers. A Rennes hospital team shares with us the results of a retrospective study on the interest of the autonomous insertion of nasogastric tubes by hypnotic accompaniment.

Parental satisfaction of child's perioperative care.

BACKGROUND: Satisfaction in the hospital setting is an important component of both hospital funding and patient experience. When it comes to a child's hospital experience, parent satisfaction of their child's perioperative care is also necessary to understand. However, little research has been conducted on the predictors of this outcome. Therefore, the purpose of this current study was to validate a priori selected predictors for parental satisfaction in their child's perioperative process. METHODS: Eight hundred and ten pediatric patients who underwent tonsillectomy and adenoidectomy surgery and their parents were included in this study. The primary outcome was assessed using a 21-item parent satisfaction questionnaire resulting in three satisfaction scores: overall care satisfaction, OR/induction satisfaction, and total satisfaction. RESULTS: Descriptive statistics and correlational analysis found that sedative-premedication, parental presence at anesthesia induction, child social functioning, parental anxiety, and language were all significant predictors of various components of the satisfaction score. Regression models, however, revealed that only parent anxiety and child social functioning remained significant predictors such that parents who reported lower state anxiety (OR/induction satisfaction: OR = 0.975, 95% CI [0.957, 0.994]; total satisfaction: OR = 0.968, 95% CI [0.943, 0.993]) and who had higher socially functioning children (overall care satisfaction: OR = 1.019, 95% CI [1.005, 1.033]; OR/induction satisfaction: OR = 1.011, 95% CI [1.000, 1.022]) were significantly more satisfied with the perioperative care they received. CONCLUSION: Lower parent anxiety and higher child social functioning were predictive of higher parental satisfaction scores.

Hypnosis for burn wound care pain and anxiety: A systematic review and meta-analysis.

BACKGROUND: Evidence from clinical trials suggests psychological interventions should be considered as an adjunct to medications. OBJECTIVE: The purpose of this systematic review and meta-analysis was to evaluate the effectiveness of clinical hypnosis on pain, anxiety and medication needs during wound care in adults suffering from a burn injury. DATA SOURCES: Medline, PsychINFO, CINAHL, Embase, ISI, SCOPUS, Cochrane, and Proquest databases were searched for randomized controlled trials comparing hypnosis to other interventions during dressing change in adult patients. DATA SYNTHESIS: Two independent reviewers extracted relevant articles and assessed their methodological quality. Only six studies met the inclusion criteria and were described in detail. Available data was pooled with Revman 5.3. RESULTS: For the primary outcome, we found a statistically significant difference in pain intensity ratings favoring hypnosis (MD=-8.90, 95% CI -16.28, -1.52). For the secondary outcomes, there was a statistically significant difference in anxiety ratings favoring hypnosis (MD=-21.78, 95% CI -35.64, -7.93) and no difference in medication usage (MD=-0.07, 95% CI -0.32, 0.17). CONCLUSION: These results suggest that hypnosis reduces pain intensity and anxiety ratings in adults undergoing burn wound care. However, because of the limitations discussed, clinical recommendations are still premature.
