Spinal Involvement of TRPV1 and PI3K/AKT/mTOR Pathway During Chronic Postoperative Pain in Mice

BACKGROUND

Chronic postoperative pain (CPOP) is among the main consequences of surgical procedures, directly affecting the quality of life. Although many strategies have been used to treat this symptom, they are often ineffective. Thus, studies investigating CPOP-associated mechanisms may help to develop more effective treatment strategies. Therefore, the present study investigated the spinal participation of the transient potential receptor vanilloid type 1 (TRPV1) and PI3K/AKT/mTOR pathway activation during CPOP.

METHODS

In this study C57BL/6 male mice were used, and CPOP was induced by muscle retraction and incision. The nociceptive threshold was measured by the von Frey filament test. For pharmacological evaluation, TRPV1 and PI3K/AKT/mTOR inhibitors were administered intrathecally. TRPV1 and PI3K/AKT/mTOR protein levels were evaluated by Western blotting.

RESULTS

The results showed that CPOP increased TRPV1 and mTOR protein levels, and pretreatment with the specific inhibitors alleviated CPOP. In addition, pretreatment with the TRPV1 antagonist SB-366791 attenuated mTOR protein levels.

CONCLUSIONS

The results suggest that TRPV1 and the PI3K/AKT/mTOR pathway are involved in CPOP at the spinal level, and TRPV1 may activate mTOR during this process.

Experiences and perspectives of adults on using opioids for pain management in the postoperative period: A scoping review

BACKGROUND

Opioids play an important role in peri-operative pain management. However, opioid use is challenging for healthcare practitioners and patients because of concerns related to opioid crises, addiction and side effects.

OBJECTIVE

This review aimed to identify and synthesise the existing evidence related to adults' experiences of opioid use in postoperative pain management.

DESIGN

Systematic scoping review of qualitative studies. Inductive content analysis and the Theoretical Domains Framework (TDF) were applied to analyse and report the findings and to identify unexplored gaps in the literature.

DATA SOURCES

Ovid MEDLINE, PsycInfo, Embase, CINAHL (EBSCO), Cochrane Library and Google Scholar.

ELIGIBILITY CRITERIA

All qualitative and mixed-method studies, in English, that not only used a qualitative approach that explored adults' opinions or concerns about opioids and/or opioid reduction, and adults' experience related to opioid use for postoperative pain control, including satisfaction, but also aspects of overall quality of a person's life (physical, mental and social well being).

RESULTS

Ten studies were included; nine were qualitative ( n  = 9) and one used mixed methods. The studies were primarily conducted in Europe and North America. Concerns about opioid dependence, adverse effects, stigmatisation, gender roles, trust and shared decision-making between clinicians and patients appeared repeatedly throughout the studies. The TDF analysis showed that many peri-operative factors formed people's perceptions and experiences of opioids, driven by the following eight domains: Knowledge, Emotion, Beliefs about consequences, Beliefs about capabilities, Self-confidence, Environmental Context and Resources, Social influences and Decision Processes/Goals. Adults have diverse pain management goals, which can be categorised as proactive and positive goals, such as individualised pain management care, as well as avoidance goals, aimed at sidestepping issues such as addiction and opioid-related side effects.

CONCLUSION

It is desirable to understand the complexity of adults' experiences of pain management especially with opioid use and to support adults in achieving their pain management goals by implementing an individualised approach, effective communication and patient-clinician relationships. However, there is a dearth of studies that examine patients' experiences of postoperative opioid use and their involvement in opioid usage decision-making. A summary is provided regarding adults' experiences of peri-operative opioid use, which may inform future researchers, healthcare providers and guideline development by considering these factors when improving patient care and experiences.

Postoperative Pain Management in Coronary Artery Bypass Grafting: An Integrative Review

PURPOSE

To identify pharmacological and nonpharmacological interventions adopted for pain relief in the postoperative period of coronary artery bypass graft surgery.

DESIGN

Integrative review.

METHODS

Studies published in English, Spanish, and Portuguese from January 2010 to December 2019 in Cumulative Index to Nursing and Allied Health Literature (CINAHL), Latin American and Caribbean Literature on Health Science, PubMed, and Web of Science. Two hundred studies were identified and eleven were included. Methodological analysis was performed using the Medical Education Research Study Quality Instrument.

FINDINGS

The studies found were organized into three thematic categories: pharmacological interventions (methadone, morphine, lidocaine gel, remifentanil, sufentanil, and nefopam), nonpharmacological interventions (low-level laser therapy, light-emitting diode, Class IV laser, and transcutaneous nerve stimulation) and anesthetic techniques (dexmedetomidine, ultrasound-guided pectoral nerve block, high thoracic epidural analgesia, and perioperative parasternal block with levobupivacaine).

CONCLUSIONS

A greater tendency to use drug strategies for postoperative pain relief was identified. The drugs used demonstrated efficacy and safety in the treatment of pain, with the exception of nefopam, which showed little benefit in this population. Nonpharmacological interventions, used as adjuvants to drug treatment, were shown to be safe, effective, and well tolerated by the patients.

Psychometric Properties and The Best Form of The Revised Short-Form Mc-Gill Pain Questionnaire in Iranian Burn Patients

Pain is the most important factor that forces patients to seek help from health care systems. Burn injuries are associated with severe pain and the assessment and interventions are a focus of nursing care. The aim of this study was to evaluate the psychometric properties of the revised short-form Mc-Gill Pain Questionnaire (MPQ) in burn patients. The present study is a methodological study in which 153 burn patients were included by convenience sampling. To evaluate the psychometric properties of the 22-item revised MPQ, face validity, construct validity (exploratory factor analysis), and reliability were determined by Cronbach's α coefficient and split-half method. Data analysis was performed using SPSS22.0 software. During the quantitative face validity test, four items were removed from the instrument due to the impact score of less than 1.5 by burn patients. The results of exploratory factor analysis showed five factors (emotional, neuropathic, continuous, stimulatory, and shooting), which explained 72.32% of the total variance. The overall Cronbach's instrument was 0.836 and the coefficient obtained by the split-half method was 0.81. According to the validity and reliability, the 18-item MPQ obtained in the present study can be used to assess pain in Persian-speaking adult burn patients.

Healthcare delivery gaps in pain management within the first 3 months after discharge from inpatient noncardiac surgeries: a scoping review

BACKGROUND

Poor pain control during the postoperative period has negative implications for recovery, and is a critical risk factor for development of persistent postsurgical pain. The aim of this scoping review is to identify gaps in healthcare delivery that patients undergoing inpatient noncardiac surgeries experience in pain management while recovering at home.

METHODS

Searches were conducted by a medical librarian in PubMed, MEDLINE, EMBASE, EBSCO CINAHL, Web of Science, and Cochrane Database of Systematic Reviews for articles published between 2016 and 2022. Inclusion criteria were adults (≥18 yr), English language, inpatient noncardiac surgery, and included at least one gap in care for acute and/or persistent pain management after surgery within the first 3 months of recovery at home. Two reviewers independently screened articles for inclusion and extracted data. Quotations from each article related to gaps in care were synthesised using thematic analysis.

RESULTS

There were 4794 results from databases and grey literature, of which 38 articles met inclusion criteria. From these, 23 gaps were extracted, encompassing all six domains of healthcare delivery (capacity, organisational structure, finances, patients, care processes and infrastructure, and culture). Identified gaps were synthesised into five overarching themes: education (22 studies), provision of continuity of care (21 studies), individualised management (10 studies), support for specific populations (11 studies), and research and knowledge translation (10 studies).

CONCLUSIONS

This scoping review identified health delivery gaps during a critical period in postoperative pain management. These gaps represent potential targets for quality improvement and future research to improve perioperative care and longer-term patient-centred outcomes.

The effect of discharge training with the teach-back method on post-discharge challenges in lumbar disc herniation patients: A quasi-experimental study

BACKGROUND

Shortened length of hospital stay in patients undergoing lumbar disc herniation surgery forces to undertake interventions that facilitate optimal patient outcomes.

AIM

The aim of this study was to investigate the effect of discharge training given by teach-back method, and counseling based on individual needs and a study-specific training booklet on postoperative pain and challenges experienced by lumbar disc herniation patients.

METHODS

This study had a quasi-experimental design and was conducted with 94 patients. Patients were divided into a control group (n = 48) and an intervention group (n = 46) using the blocking method. The pain was assessed at the time of patient admission, at discharge, and at follow-up; postoperative challenges were evaluated at discharge and follow-up.

RESULTS

Most patients experienced pain and challenges such as kinesiophobia, weakness-exhaustion-fatigue, irritability, constipation, and insomnia. The patients in the intervention group had less back and leg pain and challenges.

CONCLUSIONS

The benefits of education given by teach-back method, and counseling in reducing the postoperative problems experienced by patients who underwent surgery for lumbar disc herniation were demonstrated in this study. The findings suggest that study-specific training and counseling may be useful for addressing the pain and challenges of patients with lumbar disc herniation.

Map of Pain Education in Latin America: current state and perspectives

The Latin American Map of Pain Education initiative has developed steadily in recent years. A recent survey yields important new data on the current state and allows outlining of the next steps to improve pain education in Latin American countries. A survey conducted by Federación Latinoamericana de Asociaciones para el Estudio del Dolor (FEDELAT) with data from 19 Latin American countries showed that a generally observed barrier is the lack of adequately trained pain professionals and the insufficient number of pain centers. There is a need for formal programs of pain education and palliative care in undergraduate and graduate programs. These programs should be accessible not only to physicians but to all types of healthcare professionals involved in the management of pain patients. The article includes some recommendations that will certainly be helpful in improving pain education over the next decade in Latin America.

Predicting factors that determine patients' satisfaction with post-operative pain management following abdominal surgeries at Komfo Anokye Teaching Hospital, Kumasi, Ghana

Introduction

Poorly controlled postoperative pain has been known to be characterized by longer post-operative care, longer hospital stays with increased readmission rates, and decreased patient satisfaction. Post-operative pain has been continuously addressed in the past three (3) to four (4) decades and has been shown that 20 to 80% of post-operative patients suffer ineffective pain management.

Objective

The study was aimed at assessing the factors that may predict the satisfaction of patients with early postoperative pain management following abdominal surgeries at the Komfo Anokye Teaching Hospital, Kumasi.

Methodology

A descriptive cross-sectional study was conducted among patients who had undergone abdominal surgeries between October 2019 and December 2019 at the Komfo Anokye Teaching Hospital. Structured questionnaires based on the IPO-Q were used to obtain responses from the patients. Descriptive and Inferential statistical analysis were employed in analyzing the data obtained from the respondents of the study.

Results

138 patients were involved in this study. The mean age of patients in the study was 45.81 (±16.81) years. A higher percentage, 58.7% of the patients were males. 39.1% had completed their tertiary level of education. The majority (50.7%) of the patients had had persistent pain for more than three (3) months. The satisfaction of the patients with the post-operative pain management received was generally high among a significant majority of the patients. Meanwhile, among the factors that influence the satisfaction of the patients with the post-operative pain management received, type of analgesia and pain relief methods (Pearson Coefficient = 0.523, p-value <0.05), patient’s ability to request more pain relief, (Pearson Coefficient = 0.29, p-value <0.05), patient’s access to information about their pain treatment options from the Nurses (Pearson coefficient = -0.22, p<0.05), were the only predictors of satisfaction in patients.

Conclusion

This study found out that patients were generally satisfied with the post-operative pain management offered by their healthcare providers although the degree of satisfaction depended largely on the type of analgesia and pain relief methods, the ability to request for more pain relief, and access to information on pain treatment.

Towards Better Perioperative Pain Management in Mexico: A Study in a Network of Hospitals Using Quality Improvement Methods from PAIN OUT

Objective

This was a pre–post study in a network of hospitals in Mexico-City, Mexico. Participants developed and implemented Quality Improvement (QI) interventions addressing perioperative pain management.

Methods

PAIN OUT, an international QI and research network, provided tools for web-based auditing and feedback of pain management and patient-reported outcomes (PROs) in the clinical routine. Ward- and patient-level factors were evaluated with multi-level models. Change in proportion of patients reporting worst pain ≥6/10 between project phases was the primary outcome.

Results

Participants created locally adapted resources for teaching and pain management, available to providers in the form of a website and a special issue of a national anesthesia journal. They offered teaching to anesthesiologists, surgeons, including residents, and nurses. Information was offered to patients and families. A total of 2658 patients were audited in 9 hospitals, between July 2016 and December 2018. Participants reported that the project made them aware of the importance of: training in pain management; auditing one’s own patients to learn about PROs and that QI requires collaboration between multi-disciplinary teams. Participants reported being unaware that their patients experienced severe pain and lacked information about pain treatment options. Worst pain decreased significantly between the two project phases, as did PROs related to pain interfering with movement, taking a deep breath/coughing or sleep. The opportunity of patients receiving information about their pain treatment options increased from 44% to 77%.

Conclusions

Patients benefited from improved care and pain-related PROs. Clinicians appreciated gaining increased expertise in perioperative pain management and methods of QI.

A survey of postoperative pain treatments and unmet needs

More than 300 million patients undergo surgery worldwide each year. Pain associated with these procedures is associated with short- and long-term negative sequelae for patients, healthcare providers, and healthcare systems. The following chapter is a review of the reality of postoperative pain management in everyday clinical routine based on survey- and registry-derived data with a focus on care in adults. Between 30% and up to 80% of patients report moderate to severe pain in the days after surgery. Structures, processes, and outcomes vary widely between hospitals and indicate gaps between evidence-based findings and practice. Pain assessment is not effectively implemented in many hospitals and should consider cultural differences. Few data exist on the situation of pain management in low- and middle-income countries, indicating lack of resources and available medication in many of these areas. Certain types of surgery as well as demographic and clinical factors are associated with increased risk of severe postoperative pain.

Prevalence and avoidability of surgical adverse events in a teaching hospital in Brazil

OBJECTIVE

to estimate the prevalence and avoidability of surgical adverse events in a teaching hospital and to classify the events according to the type of incident and degree of damage.

METHOD

cross-sectional retrospective study carried out in two phases. In phase I, nurses performed a retrospective review on a simple randomized sample of 192 records of adult patients using the Canadian Adverse Events Study form for case tracking. Phase II aimed at confirming the adverse event by an expert committee composed of physicians and nurses. Data were analyzed by univariate descriptive statistics.

RESULTS

the prevalence of surgical adverse events was 21.8%. In 52.4% of the cases, detection occurred on outpatient return. Of the 60 cases analyzed, 90% (n = 54) were preventable and more than two thirds resulted in mild to moderate damage. Surgical technical failures contributed in approximately 40% of the cases. There was a prevalence of the infection category associated with health care (50%, n = 30). Adverse events were mostly related to surgical site infection (30%, n = 18), suture dehiscence (16.7%, n = 10) and hematoma/seroma (15%, n = 9).

CONCLUSION

the prevalence and avoidability of surgical adverse events are challenges faced by hospital management.
