Technology-Based Music Interventions to Reduce Anxiety and Pain Among Patients Undergoing Surgery or Procedures: Systematic Review of the Literature.

BACKGROUND: Hospitalized patients undergoing surgery or procedures may experience negative symptoms. Music is a nonpharmacological complementary approach and is used as an intervention to reduce anxiety, stress, and pain in these patients. Recently, music has been used conveniently in clinical situations with technology devices, and the mode of providing music is an important factor in technology-based music interventions. However, many reviews have focused only on the effectiveness of music interventions. OBJECTIVE: We aimed to review randomized controlled trials (RCTs) of technology-based music interventions for reducing anxiety and pain among patients undergoing surgery or procedures. We examined the clinical situation, devices used, delivery methods, and effectiveness of technology-based music interventions in primary articles. METHODS: The search was performed in the following 5 electronic databases: PubMed, MEDLINE (OvidSP), CINAHL complete, PSYCINFO, and Embase. This systematic review focused on technology-based music interventions. The following articles were included: (1) RCTs, (2) studies using interactive technology (eg, smartphones, mHealth, tablets, applications, and virtual reality), (3) empirical studies reporting pain and anxiety outcomes, and (4) English articles published from 2018 to 2023 (as of January 18, 2023). The risk of bias was assessed using the Cochrane Risk of Bias tool version 2. RESULTS: Among 292 studies identified, 21 met the inclusion criteria and were included. Of these studies, 9 reported that anxiety scores decreased after music interventions and 7 reported that pain could be decreased before, during, and after procedures. The methodology of the music intervention was important to the results on anxiety and pain in the clinical trials. More than 50% (13/21, 62%) of the studies included in this review allowed participants to select themes themselves. However, it was difficult to distinguish differences in effects depending on the device or software used for the music interventions. CONCLUSIONS: Technology-based music interventions could help reduce anxiety and pain among patients undergoing surgery or procedures. The findings of this review could help medical teams to choose a practical methodology for music interventions. Future studies should examine the effects of advanced technology-based music interventions using smart devices and software that promote interactions between medical staff and patients.

Pain prevalence and pain relief in end-of-life care - a national registry study.

BACKGROUND: Despite pain control being a top priority in end-of-life care, pain continues to be a troublesome symptom and comprehensive data on pain prevalence and pain relief in patients with different diagnoses are scarce. METHODS: The Swedish Register of Palliative Care (SRPC) was used to retrieve data from 2011 to 2022 about pain during the last week of life. Data were collected regarding occurrence of pain, whether pain was relieved and occurrence of severe pain, to examine if pain differed between patients with cancer, heart failure, chronic obstructive pulmonary disease (COPD) and dementia. Binary logistic regression models adjusted for sex and age were used. RESULTS: A total of 315 000 patients were included in the study. Pain during the last week of life was more commonly seen in cancer (81%) than in dementia (69%), heart failure (68%) or COPD (57%), also when controlled for age and sex, p < 0.001. Severe forms of pain were registered in 35% in patients with cancer, and in 17-21% in non-cancer patients. Complete pain relief (regardless of pain intensity) was achieved in 73-87% of those who experienced pain, depending on diagnosis. The proportion of patients with complete or partial pain relief was 99.8% for the whole group. CONCLUSIONS: The occurrence of pain, including severe pain, was less common in patients with heart failure, COPD or dementia, compared to patients with cancer. Compared with cancer, pain was more often fully relieved for patients with dementia, but less often in heart failure and COPD. As severe pain was seen in about a third of the cancer patients, the study still underlines the need for better pain management in the imminently dying. TRIAL REGISTRATION: No trial registration was made as all patients were deceased and all data were retrieved from The Swedish Register of Palliative Care database.

Impact of Intraoperative Nefopam on Postoperative Pain, Opioid Use, and Recovery Quality with Parietal Pain Block in Single-Port Robotic Cholecystectomy: A Prospective Randomized Controlled Trial.

Background and Objectives: This study explored how nefopam, a non-opioid analgesic in a multimodal regimen, impacts postoperative pain, opioid use, and recovery quality in single-port robot-assisted laparoscopic cholecystectomy (RALC) patients with a parietal pain block, addressing challenges in postoperative pain management. Materials and Methods: Forty patients scheduled for elective single-port RALC were enrolled and randomized to receive either nefopam or normal saline intravenously. Parietal pain relief was provided through a rectus sheath block (RSB). Postoperative pain was assessed using a numeric rating scale (NRS) in the right upper quadrant (RUQ) of the abdomen, at the umbilicus, and at the shoulder. Opioid consumption and recovery quality, measured using the QoR-15K questionnaire, were also recorded. Results: The 40 patients had a mean age of 48.3 years and an average body mass index (BMI) of 26.2 kg/m2. There were no significant differences in the pre- or intraoperative variables between groups. Patients receiving nefopam reported significantly lower RUQ pain scores compared to the controls, while the umbilicus and shoulder pain scores were similar. Rescue fentanyl requirements were lower in the nefopam group in both the PACU and ward. The QoR-15K questionnaire scores for nausea and vomiting were better in the nefopam group, but the overall recovery quality scores were comparable between the groups. Conclusions: Nefopam reduces RUQ pain and opioid use post-single-port RALC with a parietal pain block without markedly boosting RSB's effect on umbilicus or shoulder pain. It may also better manage postoperative nausea and vomiting, underscoring its role in analgesia strategies for this surgery.

Effectiveness of fentanyl buccal soluble film in cancer patients with inadequate breakthrough pain control.

BACKGROUND: Clinical evidence for the rapidity and effectiveness of fentanyl buccal soluble film (FBSF) in reducing pain intensity of breakthrough cancer pain (BTcP) remains inadequate. This study aimed to evaluate the efficacy of FBSF proportional to the around-the-clock (ATC) opioid regimens in rapidly relieving the intensity of BTcP episodes by determining the percentage of patients requiring further dose titration. METHODS: The study procedure included a dose-finding period followed by a 14-day observation period. Pain intensity was recorded with a Numeric Rating Scale (NRS) at onset and 5, 10, 15, and 30 min after FBSF self-administration. Meaningful pain relief was defined as the final NRS score ≤ 3. Satisfaction survey was conducted for each patient after treatment using the Global Satisfaction Scale. RESULTS: A total of 63 BTcP episodes occurred in 30 cancer patients. Only one patient required rescue medication at first BTcP episode and then achieved meaningful pain relief after titrating FBSF by 200 µg. Most BTcP episodes relieved within 10 min. Of 63 BTcP episodes, 30 (47.6%), 46 (73.0%), and 53 (84.1%) relieved within 5, 10, and 15 min after FBSF administration. Only grade 1/2 adverse events were reported, including somnolence, malaise, and dizziness. Of the 63 BTcP episodes, 82.6% were rated as excellent/good satisfaction with FBSF. CONCLUSION: FBSF can be administrated "on demand" by cancer patients at the onset of BTcP, providing rapid analgesia by achieving meaningful pain relief within 10 min. TRIAL REGISTRATION: This study was retrospectively registered 24 December, 2021 at Clinicaltrial.gov (NCT05209906): https://clinicaltrials.gov/study/NCT05209906 .

Alleviating severity of limb trauma pain with coadministration of topical sesame oil and standard treatments: A GRADE-assessed systematic review and meta-analysis of randomised controlled trials.

Recent randomised controlled trials (RCTs) have investigated the analgesic activity of sesame oil among patients with limb trauma; nevertheless, their findings are inconsistent. Hence, this review aimed to clarify the impact of topical administration of sesame oil on acute pain of adult outpatients with minor limb trauma. The online databases (e.g., Scopus, PubMed, Web of Science) were searched up to 31 January 2024. The RCTs were included if they compared the effect of applying standard treatments plus topical sesame oil to administering standard treatments alone or with a placebo/sham treatment. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) and the Cochrane Collaboration's risk of bias tool were applied to address the evidence quality and the study's methodological rigour, respectively. Four RCTs had the inclusion criteria, and their findings were pooled in a meta-analysis employing a random-effects approach. According to the pooled analysis, the reduction in mean change of the pain score from baseline to the second/third intervention day was significantly higher in favour of clients who received standard care plus daily massage of the trauma site with sesame oil compared to those who received a control condition (weighted mean difference: -1.10; 95% confidence interval [-1.62, -0.57]; p < 0.001). However, the evidence quality was moderate, and only two studies had good methodological rigour. Hence, more high-quality studies are needed to make a solid evidence-based conclusion about the favourable consequence of topical sesame oil on alleviating acute traumatic limb pain.

Enhancing Chronic Non-Cancer Pain Management: A Systematic Review of Mindfulness Therapies and Guided Imagery Interventions.

Background and Objectives: There has been an increasing interest in the use of non-pharmacological approaches for the multidimensional treatment of chronic pain. The aim of this systematic review was to assess the effectiveness of mindfulness-based therapies and Guided Imagery (GI) interventions in managing chronic non-cancer pain and related outcomes. Materials and Methods: Searching three electronic databases (Web of Science, PubMed, and Scopus) and following the PRISMA guidelines, a systematic review was performed on Randomized Controlled Trials (RCTs) and pilot RCTs investigating mindfulness or GI interventions in adult patients with chronic non-cancer pain. The Cochrane Risk of Bias Tool was utilized to assess the quality of the evidence, with outcomes encompassing pain intensity, opioid consumption, and non-sensorial dimensions of pain. Results: Twenty-six trials met the inclusion criteria, with most of them exhibiting a moderate to high risk of bias. A wide diversity of chronic pain types were under analysis. Amongst the mindfulness interventions, and besides the classical programs, Mindfulness-Oriented Recovery Enhancement (MORE) emerges as an approach that improves interoception. Six trials demonstrated that mindfulness techniques resulted in a significant reduction in pain intensity, and three trials also reported significant outcomes with GI. Evidence supports a significant improvement in non-sensory dimensions of pain in ten trials using mindfulness and in two trials involving GI. Significant effects on opioid consumption were reported in four mindfulness-based trials, whereas one study involving GI found a small effect with that variable. Conclusions: This study supports the evidence of benefits of both mindfulness techniques and GI interventions in the management of chronic non-cancer pain. Regarding the various mindfulness interventions, a specific emphasis on the positive results of MORE should be highlighted. Future studies should focus on specific pain types, explore different durations of the mindfulness and GI interventions, and evaluate emotion-related outcomes.

Comparison of the Analgesic Effect of Pericapsular Nerve Group Block and Lumbar Erector Spinae Plane Block in Elective Hip Surgery.

Background and Objectives: The aim of this study was to compare the effectiveness of pericapsular nerve group (PENG) and lumbar erector spinae plane (L-ESP) blocks, both administered with a high volume (40 mL) of local anesthetic (LA), for multimodal postoperative analgesia in patients undergoing hip surgery. Materials and Methods: This was a prospective, double-blind, randomized study that included 75 adult patients who were divided into three equal groups: control, PENG, and L-ESP. The study compared pain intensity, morphine consumption, time to first morphine request, and postoperative satisfaction between the control group, which received standard multimodal analgesia, and the block groups, which received PENG or L-ESP block in addition to multimodal analgesia. The numerical rating scale (NRS) was used to measure pain intensity. Results: The results showed that the block groups had lower pain intensity scores and morphine consumption, a longer time to the first morphine request, and higher postoperative satisfaction compared to the control group. The median maximum NRS score during the first 12 h was four in the control group, two in the PENG group, and three in the L-ESP group. The control group (21.52 ± 9.63 mg) consumed more morphine than the two block groups (PENG, 11.20 ± 7.55 mg; L-ESP, 12.88 ± 8.87 mg) and requested morphine 6.8 h earlier and 5 h earlier than the PENG and L-ESP groups, respectively. The control group (median 3) had the lowest Likert satisfaction scores, while the PENG group (median 4) had the lowest NRS scores (L-ESP, median 4). Conclusions: The application of PENG or L-ESP blocks with high-volume LA in patients undergoing hip surgery reduces the need for postoperative analgesia and improves the quality of multimodal analgesia.

[Pain therapy in urology-overview of current S3 guideline recommendations]. / Schmerztherapie in der Urologie ­ Überblick zu aktuellen Empfehlungen der S3-Leitlinen.

Dealing efficiently with patients suffering from pain is a central medical task. Pain, as an important function in developmental physiology, warns against damage to the body caused by external noxious agents as well as internal malfunctions and requires special attention in modern medicine. Peri- and postoperative pain is known to have a negative influence on postoperative convalescence. Treatment of tumor-related pain represents another relevant challenge in uro-oncology and palliative medicine. The updated guideline on perioperative pain therapy and palliative medicine for patients with incurable diseases or cancer is dedicated to these two topics.

Reducing inpatient opioid consumption after caesarean delivery: effects of an opioid stewardship programme and racial impact in a community hospital.

Caesarean section is the most common inpatient surgery in the USA, with more than 1.1 million procedures in 2020. Similar to other surgical procedures, healthcare providers rely on opioids for postoperative pain management. However, current evidence shows that postpartum patients usually experience less pain due to pregnancy-related physiological changes. Owing to the current opioid crisis, public health agencies urge providers to provide rational opioid prescriptions. In addition, a personalised postoperative opioid prescription may benefit racial minorities since research shows that this population receives fewer opioids despite greater pain levels. Our project aimed to reduce inpatient opioid consumption after caesarean delivery within 6 months of the implementation of an opioid stewardship programme.A retrospective analysis of inpatient opioid consumption after caesarean delivery was conducted to determine the baseline, design the opioid stewardship programme and set goals. The plan-do-study-act method was used to implement the programme, and the results were analysed using a controlled interrupted time-series method.After implementing the opioid stewardship programme, we observed an average of 80% reduction (ratio of geometric means 0.2; 95% CI 0.2 to 0.3; p<0.001) in inpatient opioid consumption. The institution designated as control did not experience relevant changes in inpatient opioid prescriptions during the study period. In addition, the hospital where the programme was implemented was unable to reduce the difference in inpatient opioid demand between African Americans and Caucasians.Our project showed that an opioid stewardship programme for patients undergoing caesarean delivery can effectively reduce inpatient opioid use. PDSA, as a quality improvement method, is essential to address the problem, measure the results and adjust the programme to achieve goals.

Continuous Ambulatory Delivery Device Use for Patients Managed by an Inpatient Palliative Care Team.

BACKGROUND: The use of Patient Controlled Analgesia (PCA) via a Continuous Ambulatory Delivery Device (CADD) is a common and effective means of pain and symptom management for hospitalized patients with a malignancy. Studies exploring the indications for starting such a device for hospitalized inpatients referred to inpatient palliative care teams are limited. AIM: This retrospective chart review aims to explore indications, timing of initiation, and barriers to the use of a CADD. METHODS: Over a six month period, during daily inpatient palliative care consult team rounds, patients who required a CADD were enrolled in this study. Sixty-one adult patients were identified who required a pump for symptom control. The team's database sheets were used to capture patient demographics. RESULTS: The main reasons for initiating a Continuous Ambulatory Delivery Device in the above setting included: lack of efficacy of oral opioids and to increase patient autonomy of their pain management. Approximately 20% of patients required transfer to another unit that could accommodate the CADD. The median length of stay for these patients was 13 days, with a median length of half a day for a pump to be started. CONCLUSIONS: This initial study provides the Palliative Care Consult Team with information on the indications for the use of a CADD. The lack of universal access to a CADD in various areas of our hospital due to differences in departmental protocols may compromise good symptom management and patient safety. These results strengthen the argument that the existing hospital policy requires revamping to improve CADD access. A CADD has been shown to provide hospitalized patients, with a malignancy, with timely access to effective symptom management, and in turn, reducing their length of stay in hospital. These findings will help inform this organization's CADD policy and support the need to broaden access to this device.

Efficacy of Lidocaine Spray for Pain Reduction during Colposcopy-Directed Cervical Biopsies: A Randomized Controlled Trial.

Objectives: The objective of this study was to evaluate the efficacy of lidocaine spray in reducing the pain during colposcopy-directed cervical biopsy (CDB). Methods: From December 2017 to February 2019, 312 women undergoing CDBs were enrolled. The participants were randomized to three groups: group 1 (lidocaine spray), in which lidocaine spray was applied thoroughly to the cervix; group 2 (placebo), in which normal saline was applied thoroughly to the cervix; and group 3 (control), in which no anesthetic agent was applied to the cervix. Each woman completed a 10 cm visual analog scale to classify the subjective pain experience at three time points: baseline, immediately after biopsy, and 10 min after the procedure. The primary outcome of this study was the biopsy pain score. Results: The 312 enrolled women were randomly assigned to the three groups, amounting to 104 women per group. The clinical and pathological characteristics of the participants in all groups were comparable. The baseline, the biopsy, and the post-procedure pain scores were comparable among the three groups. There was a significant increase in the pain score from baseline to biopsy and from baseline to post-procedure in each group. The pain-score changes from baseline to biopsy in the lidocaine spray group significantly decreased when compared with the normal saline group (<0.001), and tended to decrease, though not significantly (p = 0.06), when compared with the control group. No complication with the intervention was observed. Conclusions: The application of lidocaine spray to the cervix has the benefit of reducing the pain associated with CDBs by a small amount. However, the intervention is safe and may be considered in nulliparous and/or overly anxious women undergoing the procedure.

Barriers to Pain Management as Perceived by Cancer and Noncancer Patients With Chronic Disease.

BACKGROUND: Pain is the most common symptom experienced by both cancer and non-cancer patients. A wide variety of barriers may hinder the optimal treatment of cancer and noncancer pain that are related to the health care system, health care providers, and patients. PURPOSE: To explore the barriers to pain management as perceived by patients with cancer and noncancer chronic diseases. METHOD: A descriptive, cross-sectional correlational design was employed to recruit a sample of 200 patients (n = 100 patients with cancer, n= 100 patients with noncancer) from two hospitals in Jordan. Patients filled out an Arabic version of Barriers Questionnaire II (ABQ-II). RESULTS: Harmful effects of medications were the greatest barrier to effective pain management, while fatalism had the lowest mean scores. Age was negatively correlated with physiological effects (r = -0.287, p < .01), communication (r = -0.263, p < .01), harmful effects (r = -0.284, p < .01), and the overall barrier score (r = -0.326, p < .01) among noncancer patients with chronic disease and (p > .05) for patients with cancer. Patients with cancer had higher mean scores (M = 2.12, SD = 0.78) in the fatalism subscale than those with noncancer chronic disease (M = 1.91, SD = 0.68), while patients with noncancer chronic disease had significantly higher mean scores (M = 2.78, SD = 0.78) in the communication subscale than patients with cancer (M = 2.49, SD = 0.65), (t = -2.899, p = .005). CONCLUSION: To improve the quality of care for patients who are in pain, it is recommended to address pain management barriers as they arise.

Effect of Education on Symptom Management and Control in Cancer Patients Receiving Palliative Care.

OBJECTIVE: This study aims to investigate the effect of an educational intervention on cancer patients receiving palliative care and their caregivers concerning symptom management and family needs. METHODS: This study involved 120 participants-60 cancer patients and their respective caregivers-divided into intervention and control groups. Over a 2-week period, the intervention group received a comprehensive educational program focusing on symptom management, while the control group did not receive any educational intervention. The Edmonton Symptom Assessment System (ESAS) and Palliative Performance Scale (PPS) were used to assess patients' symptoms, their intensity, and performance, while the Family Need Scale (FNS) was utilized to evaluate caregivers' needs. These assessments were conducted at the beginning and end of the study. Primary outcomes focused on symptom assessment using ESAS and PPS, along with evaluating caregivers' needs through FNS. Secondary outcomes involved assessing participant satisfaction with the intervention. RESULTS: At the end of the study, comparing initial and second evaluations, both ESAS and PPS scores significantly increased in the intervention and control groups (p = .003, p = .002, respectively). Additionally, a statistically significant decrease in the severity of symptoms, except for lethargy/hypokinesis, was observed in the intervention group compared to the control group. The FNS scale indicated that family needs satisfaction was higher in the intervention group compared to the control group. The data obtained demonstrated that there was a reduction the pain, fatigue, depression, anxiety, drowsiness, and shortness of breath levels in the intervention group compared to the control group, but there was no significant difference other than these symptoms. CONCLUSIONS: The educational intervention positively impacted symptom management and family needs. Optimizing symptom control would greatly benefit palliative care patients and their caregivers.

Effects of Integrated Music-Video Therapy on Pain and Anxiety During High-Dose-Rate Brachytherapy.

PURPOSE: This study aimed to examine the effect of integrated music-video therapy on pain and anxiety of gynecologic cancer patients at different stages of brachytherapy. DESIGN: This study used a single-group crossover design. METHODS: Data on 27 patients diagnosed with gynecologic cancer and receiving brachytherapy were collected from February 2018 to January 2019. Participants' pain and anxiety levels were measured four times using a numerical rating scale (before, during, after applicator insertion, and during the radiation). In addition, vital signs were measured three times (before, after applicator insertion, and during radiation). Data were analyzed for frequency and percentage. The normality and homogeneity of the dependent variables were tested using the Kolmogorov-Smirnov and Mann-Whitney U tests, respectively. RESULTS: Significant differences were found between the experimental and control phases in pain degree during radiation exposure (Z = -1.68, p = .046) and anxiety degree during applicator insertion (Z=-4.42, p = .000), after applicator insertion (Z = -4.85, p = .000), and during radiation exposure (Z = -5.38, p = .000). However, no significant difference was found between the changes in blood pressure, pulse, and respiration at any time point. CONCLUSIONS: The findings suggest the need to actively employ integrated music-video therapy to reduce acute pain and anxiety in gynecologic cancer patients undergoing brachytherapy. CLINICAL IMPLICATIONS: This study provides insights into the methodological approaches for implementing integrated music-video therapy in clinical practice, targeting the reduction of acute pain and anxiety triggered by gynecological surgeries and procedures.

Perspectives and Practice in Eastern and Western Medicine for Pain Management in Rehabilitation Training after Orthopedic Trauma Surgery: A Qualitative Study.

BACKGROUND: Despite the increasing emphasis on rehabilitation training after orthopedic surgery, little is known about the pain caused by the procedure itself. Clinical practice is driven by beliefs in pain management. AIMS: This study aimed to explore the perspective of pain management during rehabilitation training after orthopedic trauma in China and its influencing factors from different perspectives in traditional Chinese medicine and Western medicine, respectively. DESIGN: A phenomenological qualitative study involving semi-structured interviews. SETTINGS:   METHODS: A qualitative study was conducted with 16 medical workers working in the Rehabilitation Medicine Department in eastern China from July 2022-February 2023. A directed method to thematic analysis was used to code the transcribed data and identify themes. RESULTS: Four main themes emerged. (1) Inconsistent perspectives and practice: Chinese doctors majoring in Western medicine felt sympathy, helpless, and had a lack of knowledge and misconception about pain. Traditional Chinese medicine deemed that pain is a protective mechanism and attached importance to holism and unique means. (2) Consistent outcome: Insufficient pain management will have a series of negative consequences for patients' recovery, forming a vicious cycle. (3) Expectations: Though they are not optimistic about traditional analgesics, enhancement, cooperation and ideal analgesic methods still be expressed, and (4) Concept transformation: Conducting nitrous oxide is a process not only to promote analgesic technology but also to promote the awareness and concept of pain management. CONCLUSIONS: Our study emphasized that medical workers should be aware of the importance of pain management at the same time while treating the disability. The study provides insight into pain management experiences within different educational backgrounds. The findings enable professionals to recognize the importance of pain management and its influencing factors to provide feasible and effective pain management strategies.

Gaps in standardized postoperative pain management quality measures: A systematic review.

BACKGROUND: The goal of this study was an assessment of availability postoperative pain management quality measures and National Quality Forum-endorsed measures. Postoperative pain is an important clinical timepoint because poor pain control can lead to patient suffering, chronic opiate use, and/or chronic pain. Quality measures can guide best practices, but it is unclear whether there are measures for managing pain after surgery. METHODS: The National Quality Forum Quality Positioning System, Agency for Healthcare Research and Quality Indicators, and Centers for Medicare and Medicaid Services Measures Inventory Tool databases were searched in November 2019. We conducted a systematic literature review to further identify quality measures in research publications, clinical practice guidelines, and gray literature for the period between March 11, 2015 and March 11, 2020. RESULTS: Our systematic review yielded 1,328 publications, of which 206 were pertinent. Nineteen pain management quality measures were identified from the quality measure databases, and 5 were endorsed by National Quality Forum. The National Quality Forum measures were not specific to postoperative pain management. Three of the non-endorsed measures were specific to postoperative pain. CONCLUSION: The dearth of published postoperative pain management quality measures, especially National Quality Forum-endorsed measures, highlights the need for more rigorous evidence and widely endorsed postoperative pain quality measures to guide best practices.

Effect of Pain Reprocessing Therapy vs Placebo and Usual Care for Patients With Chronic Back Pain: A Randomized Clinical Trial.

Importance: Chronic back pain (CBP) is a leading cause of disability, and treatment is often ineffective. Approximately 85% of cases are primary CBP, for which peripheral etiology cannot be identified, and maintenance factors include fear, avoidance, and beliefs that pain indicates injury. Objective: To test whether a psychological treatment (pain reprocessing therapy [PRT]) aiming to shift patients' beliefs about the causes and threat value of pain provides substantial and durable pain relief from primary CBP and to investigate treatment mechanisms. Design, Setting, and Participants: This randomized clinical trial with longitudinal functional magnetic resonance imaging (fMRI) and 1-year follow-up assessment was conducted in a university research setting from November 2017 to August 2018, with 1-year follow-up completed by November 2019. Clinical and fMRI data were analyzed from January 2019 to August 2020. The study compared PRT with an open-label placebo treatment and with usual care in a community sample. Interventions: Participants randomized to PRT participated in 1 telehealth session with a physician and 8 psychological treatment sessions over 4 weeks. Treatment aimed to help patients reconceptualize their pain as due to nondangerous brain activity rather than peripheral tissue injury, using a combination of cognitive, somatic, and exposure-based techniques. Participants randomized to placebo received an open-label subcutaneous saline injection in the back; participants randomized to usual care continued their routine, ongoing care. Main Outcomes and Measures: One-week mean back pain intensity score (0 to 10) at posttreatment, pain beliefs, and fMRI measures of evoked pain and resting connectivity. Results: At baseline, 151 adults (54% female; mean [SD] age, 41.1 [15.6] years) reported mean (SD) pain of low to moderate severity (mean [SD] pain intensity, 4.10 [1.26] of 10; mean [SD] disability, 23.34 [10.12] of 100) and mean (SD) pain duration of 10.0 (8.9) years. Large group differences in pain were observed at posttreatment, with a mean (SD) pain score of 1.18 (1.24) in the PRT group, 2.84 (1.64) in the placebo group, and 3.13 (1.45) in the usual care group. Hedges g was -1.14 for PRT vs placebo and -1.74 for PRT vs usual care (P < .001). Of 151 total participants, 33 of 50 participants (66%) randomized to PRT were pain-free or nearly pain-free at posttreatment (reporting a pain intensity score of 0 or 1 of 10), compared with 10 of 51 participants (20%) randomized to placebo and 5 of 50 participants (10%) randomized to usual care. Treatment effects were maintained at 1-year follow-up, with a mean (SD) pain score of 1.51 (1.59) in the PRT group, 2.79 (1.78) in the placebo group, and 3.00 (1.77) in the usual care group. Hedges g was -0.70 for PRT vs placebo (P = .001) and -1.05 for PRT vs usual care (P < .001) at 1-year follow-up. Longitudinal fMRI showed (1) reduced responses to evoked back pain in the anterior midcingulate and the anterior prefrontal cortex for PRT vs placebo; (2) reduced responses in the anterior insula for PRT vs usual care; (3) increased resting connectivity from the anterior prefrontal cortex and the anterior insula to the primary somatosensory cortex for PRT vs both control groups; and (4) increased connectivity from the anterior midcingulate to the precuneus for PRT vs usual care. Conclusions and Relevance: Psychological treatment centered on changing patients' beliefs about the causes and threat value of pain may provide substantial and durable pain relief for people with CBP. Trial Registration: ClinicalTrials.gov Identifier: NCT03294148.

PROSPECT guidelines for video-assisted thoracoscopic surgery: a systematic review and procedure-specific postoperative pain management recommendations.

Video-assisted thoracoscopic surgery has become increasingly popular due to faster recovery times and reduced postoperative pain compared with thoracotomy. However, analgesic regimens for video-assisted thoracoscopic surgery vary significantly. The goal of this systematic review was to evaluate the available literature and develop recommendations for optimal pain management after video-assisted thoracoscopic surgery. A systematic review was undertaken using procedure-specific postoperative pain management (PROSPECT) methodology. Randomised controlled trials published in the English language, between January 2010 and January 2021 assessing the effect of analgesic, anaesthetic or surgical interventions were identified. We retrieved 1070 studies of which 69 randomised controlled trials and two reviews met inclusion criteria. We recommend the administration of basic analgesia including paracetamol and non-steroidal anti-inflammatory drugs or cyclo-oxygenase-2-specific inhibitors pre-operatively or intra-operatively and continued postoperatively. Intra-operative intravenous dexmedetomidine infusion may be used, specifically when basic analgesia and regional analgesic techniques could not be given. In addition, a paravertebral block or erector spinae plane block is recommended as a first-choice option. A serratus anterior plane block could also be administered as a second-choice option. Opioids should be reserved as rescue analgesics in the postoperative period.
