The Effect of Hypnotherapy on Pain Intensity in Postoperative Patients: A Systematic Review

Background: Pain is a common problem in patients undergoing surgery. The constant postoperative acute pain can affect the physiological and psychological aspects of the patient.Objective: Non-pharmacological therapy is widely used for the treatment of chronic pain. Non-pharmacological therapy needs to be developed in acute postoperative pain due to concerns about the side effects of pharmacological treatment. There is non-pharmacological management that effectively reduces pain intensity, namely hypnotherapy.Methods: The systematic search for this review used the Google Scholar database, Directory of Open Access Journal (DOAJ), ProQuest, and PubMed using keywords (Hypnosis OR Hypnotism OR Hypnoanalysis OR Hypnotherapy OR Hypnotherapies OR Mesmerism) AND (Post-surgical Pain OR Post surgical Pain OR Postsurgical Pain OR Post-operative Pain OR Post operative Pain OR Post-operative Pains OR Postoperative Pain OR Acute Postoperative Pain OR Acute Post-operative Pain OR Acute Post operative Pain). The quality of journals was assessed using the Critical Appraisal Skills Program (CASP) instrument. The synthesis method used was narrative synthesis (narrative synthesis).Results: 10 articles were fully reviewed from 2010-2020. The visualization technique with rapid conversational induction has the best effect than other techniques. The most effective way of conveying suggestions is indirect with a permissive approach. The study results showed that hypnotherapy tended to reduce postoperative pain in minor surgical procedures than in major surgeries.Conclusion: Hypnotherapy affects reducing the pain intensity of postoperative patients. The results of this study recommend that hypnotherapy suggestions and pain measures must be tailored to the patient's condition.

Can Acute Postoperative Pain Management After Tumour Resection Surgery Modulate Risk of Later Recurrence or Metastasis?

BackgroundCancer is a leading cause of mortality worldwide, but death is rarely from the primary tumour: Rather it is multi-organ dysfunction from metastatic disease that is responsible for up to 90% of cancer-related deaths. Surgical resection of the primary tumour is indicated in 70% of cases. The perioperative stress response, tissue hypoxia at the site of surgery, and acute pain contribute to immunosuppression and neo-angiogenesis, potentially promoting tumour survival, proliferation, and metastasis. Poorly controlled acute postoperative pain decreases Natural Killer (NK) immune cell activity, which could potentially facilitate circulating tumour cells from evading immune detection. This consequently promotes tumour growth and distal metastasis.MethodsWe conducted a comprehensive literature search for links between acute pain and cancer outcomes using multiple online databases. Relevant articles from January 1st, 2010 to September 1st, 2021 were analysed and appraised on whether postoperative pain control can modulate the risk of recurrence, metastasis, and overall cancer survival.ResultsAlthough experimental and retrospective clinical data suggest a plausible role for regional anaesthesia in cancer outcome modulation, this has not been supported by the single, largest prospective trial to date concerning breast cancer. While there are mixed results on anaesthesiology drug-related interventions, the most plausible data relates to total intravenous anaesthesia with propofol, and to systemic administration of lidocaine.ConclusionThe hypothesis that anaesthetic and analgesic technique during cancer surgery could influence risk of subsequent recurrence or metastasis has been prevalent for >15 years. The first, large-scale definitive trial among women with breast cancer found robust equivalent findings between volatile anaesthesia with opioid analgesia and regional anaesthesia. Therefore, while regional anaesthesia during tumour resection does not seem to have any effect on cancer outcomes, it remains plausible that other anaesthetic techniques (e.g. total intravenous anaesthesia and systemic lidocaine infusion) might influence oncologic outcome in other major tumour resection surgery (e.g. colorectal and lung). Therefore, another large trial is needed to definitively answer these specific research questions. Until such evidence is available, perioperative analgesia for cancer surgery of curative intent should be based on patient co-morbidity and non-cancer endpoints, such as optimising analgesia and minimising postoperative complications.

Postoperative Pain Control Following Cardiac Implantable Electronic Device Implantation

Postoperative pain following cardiac implantable electronic device (CIED) surgery may not always be adequately treated. The postoperative pain trajectory occurs over several days following the procedure with tenderness and limited arm range of motion lasting for weeks after surgery. Pain control typically commences in the perioperative period while the patient is in the hospital and may continue after discharge; outpatients may be given a prescription and advice for their analgesic regimen. It is not unusual for CIED patients to be discharged a few hours after implantation. While opioids are known as an effective analgesic to manage acute postoperative pain, growing scrutiny on opioid use as well as their side effects and potential risks have limited their use. Opioids may be considered for appropriate patients for a short course of treatment of acute postoperative pain, but other analgesics may likewise be considered.

Prevention of Acute Postoperative Pain in Breast Cancer: A Comparison between Opioids versus Ketamine in the Intraoperatory Analgesia

Background. Acute postoperative pain (APP) has a high incidence in breast surgery, and opioids are the most commonly used drugs for its management; however, they are not free from systemic side effects, which may increase comorbidity. In the past few years, opioid-free anaesthesia has been favoured with promising results. Methods. We conducted a descriptive study including 71 patients who underwent breast cancer surgery. The opioid group (n = 41) received fentanyl for induction, remifentanil for maintenance, and rescue morphine before waking up, whereas the ketamine group (n = 30) received a ketamine bolus for induction followed by continuous ketamine infusion during surgery. Later, the presence and intensity of pain were registered, using the Numeric Rating Scale (NRS 1–10) for pain, at different times in the recovery room, at 24 hours and at 3 months. Results. Administration of ketamine is more effective than opioid use for APP prevention in breast cancer surgery because the ketamine group presented with less pain than the opioid group ( p < 0.05) at all measured times. When there was pain, patients in the ketamine group gave a lower score to its intensity ( p < 0.05). Conclusions. Ketamine could reduce the incidence of APP in breast cancer surgery, compared to opioids.

Intravenous patient-controlled analgesia plus psychoeducational intervention for acute postoperative pain in patients with pulmonary nodules after thoracoscopic surgery: a retrospective cohort study

Background The association of psychological factors with postoperative pain has been well documented. The incorporation of psychoeducational intervention into a standard analgesia protocol seems to be an attractive approach for the management of acute postoperative pain. Our study aimed to evaluate the impact of psychoeducational intervention on acute postoperative pain in pulmonary nodule (PN) patients treated with thoracoscopic surgery. Methods In this study, 76 PN patients treated with thoracoscopic surgery and intravenous patient-controlled analgesia (IV-PCA) plus psychoeducational evaluation and intervention were selected as the psychoeducational intervention group (PG). Another 76 PN patients receiving IV-PCA without psychoeducational intervention after thoracoscopic surgery, treated as the control group (CG), were identified from the hospital database and matched pairwise with PG patients according to age, sex, preoperative body mass index (BMI), opioid medications used for IV-PCA and the educational attainment of patients. Results The most common psychological disorders were anxiety and interpersonal sensitivity, which were recorded from 82.9% (63/76) and 63.2% (48/76) of PG patients. The numerical rating scale (NRS) pain scores of the PG patients were significantly lower than those of the CG patients at 2 and 24 h after surgery (P < 0.001). Total opioid consumption for acute postoperative pain in the PG was 52.1 mg of morphine equivalent, which was significantly lower than that (67.8 mg) in the CG (P = 0.038). PG patients had a significantly lower incidence of rescue analgesia than CG patients (28.9% vs. 44.7%, P = 0.044). Nausea/vomiting was the most common side effect of opioid medications, recorded for 3 (3.9%) PG patients and 10 (13.2%) CG patients (P = 0.042). In addition, no significant difference was observed between PG and CG patients in terms of grade 2 or higher postoperative complications (10.5% vs. 17.1%, P = 0.240). Conclusions Psychoeducational intervention for PN patients treated with thoracoscopic surgery resulted in reduced acute postoperative pain, less opioid consumption and fewer opioid-related side effects.

Open-Label Placebo Treatment for Acute Postoperative Pain (OLP-POP Study): Study Protocol of a Randomized Controlled Trial

Introduction: Open-label placebos have been proposed as way of using long recognized analgesic placebo effects in an ethical manner. Recent evidence shows efficacy of open-label placebos for clinical conditions, but there is need for more research on open-label placebos in acute pain. In the treatment of acute postoperative pain, minimization of opioid related side effects remains one of the key challenges. Therefore, this study aims at investigating the potential of adding unconditioned open-label placebos to treatment as usual as a means of reducing opioid consumption and its related side effects in patients with acute postoperative pain.Methods and Analysis: This is the protocol of an ongoing single site randomized controlled trial. The first patient was enrolled in May 2020. In total, 70 patients suffering from acute postoperative pain following dorsal lumbar interbody fusion are randomized to either a treatment as usual group or an experimental intervention group. The treatment as usual group consists of participants receiving a patient-controlled morphine pump. On day 1 and 2 post-surgery, patients in the intervention group receive, in addition to treatment as usual, two open-label placebo injections per day along with an evidence-based treatment rationale explaining the mechanisms of placebos. The primary outcome is measured by means of self-administered morphine during day 1 and 2 post-surgery. Several other outcome measures including pain intensity and adverse events as well as potential predictors of placebo response are assessed. Analysis of covariance will be used to answer the primary research question and additional statistical techniques such as generalized linear mixed models will be applied to model the temporal course of morphine consumption.Discussion: This study will provide valuable insights into the efficacy of open-label placebos in acute pain and will potentially constitute an important step toward the implementation of open-label placebos in the clinical management of acute postoperative pain. In addition, it will shed light on a cost-efficient and patient-centered strategy to reduce opioid consumption and its related side effects, without any loss in pain management efficacy.Ethics and Dissemination: The “Ethikkommission Nordwest- und Zentralschweiz” (BASEC2020-00099) approved the study protocol. Results of the analysis will be submitted for publication in a peer-reviewed journal.Clinical Trial Registration: The study is registered at ClinicalTrials.gov (NCT04339023) and is listed in the Swiss national registry at kofam.ch (SNCTP000003720).
