Variations of the Relative Parasympathetic Tone Assessed by ANI During Oocyte Retrieval Under Local Anaesthesia with Virtual Reality : A Randomized, Controlled, Monocentric, Open Study. J Med Syst 2024; 48:39. [PMID: 38578467 DOI: 10.1007/s10916-024-02057-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2024] [Accepted: 03/25/2024] [Indexed: 04/06/2024]
Abstract
Transvaginal oocyte retrieval is an outpatient procedure performed under local anaesthesia. Hypno-analgesia could be effective in managing comfort during this procedure. This study aimed to assess the effectiveness of a virtual reality headset as an adjunct to local anaesthesia in managing nociception during oocyte retrieval. This was a prospective, randomized single-centre study including patients undergoing oocyte retrieval under local anaesthesia. Patients were randomly assigned to the intervention group (virtual reality headset + local anaesthesia) or the control group (local anaesthesia). The primary outcome was the efficacy on the ANI®, which reflects the relative parasympathetic tone. Secondary outcomes included pain, anxiety, conversion to general anaesthesia rate, procedural duration, patient's and gynaecologist's satisfaction and virtual reality headset tolerance. ANI was significantly lower in the virtual reality group during the whole procedure (mean ANI: 79 95 CI [77; 81] vs 74 95 CI [72; 76]; p < 0.001; effect size Cohen's d -0.53 [-0.83, -0.23]), and during the two most painful moments: infiltration (mean ANI: 81 +/- 11 vs 74 +/- 13; p < 0.001; effect size Cohen's d -0.54[-0.85, -0.24]) and oocytes retrieval (mean ANI: 78 +/- 11 vs 74.40 +/- 11; p = 0.020; effect size Cohen's d -0.37 [-0.67, -0.07]).There was no significant difference in pain measured by VAS. No serious adverse events related were reported. The integration of virtual reality as an hypnotic tool during oocyte retrieval under local anaesthesia in assisted reproductive techniques could improve patient's comfort and experience.

Abstract
PURPOSE OF REVIEW Chronic Postsurgical Pain (CPSP) and the risk for long-term opioid dependency are known complications following major surgery. The idea of Transitional Pain Service (TPS) has been introduced as an interdisciplinary setting to manage pain in the perioperative continuum. We expand on the basic framework and principles of TPS and summarize the current evidence of the TPS and possible interventions to adress postoperative pain. Areas of future work in TPS-related research are discussed. RECENT FINDINGS Several studies support the effectiveness of TPS in reducing opioid consumption in the perioperative period and following discharge. Some studies also show an improvement in functional outcome with TPS with patients reporting lower pain severity and pain interference. The TPS aims to halt the progress of acute postoperative pain to CPSP by providing longitudinal support with patient-centered care. While some studies suggest a positive impact of TPS implementation in terms of reduction in postoperative opioid consumption and improvement of some functional outcomes, direct evidence in terms of reduction in the incidence of CPSP is still missing. The cost-effectiveness of TPS and the expansion of TPS through e-health services and digital applications also need to be evaluated.

Postoperative accurate pain assessment of children and artificial intelligence: A medical hypothesis and planned study. World J Clin Cases 2024; 12:681-687. [PMID: 38322690 PMCID: PMC10841123 DOI: 10.12998/wjcc.v12.i4.681] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/27/2023] [Revised: 01/02/2023] [Accepted: 01/11/2024] [Indexed: 01/25/2024] Open
Abstract
Although the pediatric perioperative pain management has been improved in recent years, the valid and reliable pain assessment tool in perioperative period of children remains a challenging task. Pediatric perioperative pain management is intractable not only because children cannot express their emotions accurately and objectively due to their inability to describe physiological characteristics of feeling which are different from those of adults, but also because there is a lack of effective and specific assessment tool for children. In addition, exposure to repeated painful stimuli early in life is known to have short and long-term adverse sequelae. The short-term sequelae can induce a series of neurological, endocrine, cardiovascular system stress related to psychological trauma, while long-term sequelae may alter brain maturation process, which can lead to impair neurodevelopmental, behavioral, and cognitive function. Children's facial expressions largely reflect the degree of pain, which has led to the developing of a number of pain scoring tools that will help improve the quality of pain management in children if they are continually studied in depth. The artificial intelligence (AI) technology represented by machine learning has reached an unprecedented level in image processing of deep facial models through deep convolutional neural networks, which can effectively identify and systematically analyze various subtle features of children's facial expressions. Based on the construction of a large database of images of facial expressions in children with perioperative pain, this study proposes to develop and apply automatic facial pain expression recognition software using AI technology. The study aims to improve the postoperative pain management for pediatric population and the short-term and long-term quality of life for pediatric patients after operational event.

Raising the Bar: Multimodal Analgesia with Transdermal Lidocaine for Nuss Repair of Pectus Excavatum Decreases Length of Stay and Opioid Use. J Pediatr Surg 2023; 58:2244-2248. [PMID: 37400309 DOI: 10.1016/j.jpedsurg.2023.06.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 06/06/2023] [Accepted: 06/07/2023] [Indexed: 07/05/2023]
Abstract
INTRO Pain management for minimally invasive (Nuss) repair of pectus excavatum (PE) is challenging, particularly as the judicious use of opioids has become a patient safety priority. Multi-modal pain management protocols are increasingly used, but there is limited experience using transdermal lidocaine patches (TLP) in this patient population. METHODS Pediatric anesthesiologists and surgeons in a children's hospital within a hospital designed a multi-modal perioperative pain management protocol for patients undergoing Nuss repair of PE (IRB00068901). The protocol included use of TLP in addition to other adjuncts such as methadone, gabapentin, and NSAIDS. Following initiation of the protocol charts were reviewed retrospectively, comparing outcomes before and after implementation of the protocol. RESULTS Forty-nine patients underwent a Nuss procedure between 2013 and 2022, 15 prior to initiation of the protocol and 34 after. Patient demographics and operative length were similar between the two groups. Average length of stay decreased from 4.7 to 3.3 days and reported opioid use at the time of the first outpatient post-op visit dropped from 60% to 24% (p < 0.05). Morphine milligram equivalents (MME) usage was decreased following implementation during hospital admission, at discharge, and at first post-operative visit (464 vs. 169, 1288 vs. 218, and 214 vs. 56, respectfully, p < 0.05). There were no ED visits or readmissions <30 days related to post-operative pain. CONCLUSION Post-operative opioid usage and hospital length of stay were decreased after initiation of the protocol. Transdermal lidocaine patches may be a helpful adjunct to minimize narcotic requirements after repair of pectus excavatum. LEVEL OF EVIDENCE Level II.

Abstract
PURPOSE OF REVIEW This review evaluates disparities in acute postoperative pain management with regard to gender, race, socioeconomic status, age, and language. Strategies for addressing bias are also discussed. RECENT FINDINGS Inequities in acute postoperative pain management may lead to longer hospital stays and adverse health outcomes. Recent literature suggests that there are disparities in acute pain management related to patient gender, race, and age. Interventions to address these disparities are reviewed but require further investigation. Recent literature highlights inequities in postoperative pain management, particularly in relation to gender, race, and age. There is a need for continued research in this area. Strategies such as implicit bias training and using culturally competent pain measurement scales may help reduce these disparities. Continued efforts by both providers and institutions to address and eliminate biases in postoperative pain management are needed to ensure better health outcomes.

Abstract
PURPOSE OF REVIEW A multimodal analgesic approach improves postoperative pain relief and reduces opioid use; however, it is not universally implemented. This review presents the evidence assessing multimodal analgesic regimens and recommends optimal analgesic combinations. RECENT FINDINGS The evidence for best combinations of individual patients undergoing specific procedures is lacking. Nevertheless, an optimal multimodal regimen may be determined based on identifying efficacious, safe, and inexpensive analgesics interventions. Key components of an optimal multimodal analgesic regimen include the preoperative identification of patients at high risk for postoperative pain in addition to patient and caregiver education. Unless contraindicated, all patients should receive a combination of acetaminophen, non-steroidal anti-inflammatory drug or cycoxygenase-2-specific inhibitor, dexamethasone, and procedure-specific regional analgesic technique and/or surgical site local anesthetic infiltration. Opioids should be administered as rescue adjuncts. Non-pharmacological interventions are important components of an optimal multimodal analgesic technique. It is imperative to integrate multimodal analgesia regimens within a multidisciplinary enhanced recovery pathway.

Abstract
The serratus plane block is a regional anesthesia technique awaiting efficacy and safety evaluation in breast cancer surgery, but evidence is unclear. This meta-analysis evaluates the analgesic effectiveness of serratus plane block vis-à-vis general anesthesia and paravertebral block for breast cancer surgery. We searched for randomized controlled trials in PubMed, the Cochrane Library, and Web of Science with no language limitation, comparing the serratus plane block with multimodal analgesia or the thoracic paravertebral block in breast cancer surgery. The Hartung-Knapp-Sidik-Jonkman method in combination with a random-effects model was used to pool data. We included 12 randomized controlled trials (799 patients). Compared with multimodal analgesia, pooled outcomes favored the use of serratus plane block for effectively alleviating acute postoperative pain severity at multiple time points. The serratus plane block also resulted in decreased postoperative analgesic consumption of 28.81mg (95% confidence interval [CI]: -51.20, -6.43), decreased intraoperative fentanyl consumption of -56.46 mg (95% CI: -79.61, -33.30), increased duration of postoperative anesthesia of 243.85 min (95% CI: 104.38, 383.31), and reduced postoperative nausea and vomiting with a log relative risk of -1.07 (95% CI: -1.90, -0.24). Compared with the thoracic paravertebral block, the serratus plane block was not statically worse for all of the outcomes assessed. No adverse effects were reported. The serratus plane block effectively alleviates acute postoperative pain, reduces the rate of postoperative nausea and vomiting, and improves perioperative anesthesia outcomes in breast cancer surgery, and it may represent an alternative to thoracic paravertebral block.

Abstract
PURPOSE OF REVIEW Acupuncture is an analgesic technique that has long been utilized in Eastern medicine. In recent times, various acupuncture techniques have been used in integrated pain management approaches in Western medicine. It has even been adopted as an analgesic method in surgical patients. Currently, no review exists regarding various acupuncture techniques used in perioperative pain management and data describing the utility of these techniques. This paper synthesizes the latest literature regarding the role of acupuncture in perioperative pain management. The authors sought to describe various acupuncture modalities used to help manage surgical pain and synthesize the current body of literature to help readers make informed judgements on the topic. RECENT FINDINGS Patients undergoing abdominal, spine/neuro, and gynecologic pelvic surgery generally benefit from acupuncture. Out of the various acupuncture techniques, electroacupuncture, transcutaneous electric acupoint stimulation, and traditional total body acupuncture seem to be most promising as adjuncts to multimodal perioperative analgesia. Benefits include improved analgesia and/or reduced narcotic requirements, decrease in PONV, and shorter time to return of bowel function. Acupuncture is a low-risk method that has the potential to enhance perioperative analgesia, decrease opioid requirement, and reduce unwanted side effects of anesthesia, surgery, and opioid administration such as nausea/vomiting. Given the variety of patient populations, various acupuncture techniques, and small patient populations for most current studies; it remains difficult to determine which acupuncture method would most benefit specific patients. Future studies with more robust sample sizes and prospective comparison on acupuncture technique would help better characterize acupuncture's role in perioperative pain management.

Abstract
PURPOSE OF REVIEW The aim of this review is to discuss the use of tramadol in the perioperative period. There is no doubt that tramadol has revolutionized pain treatment, making it important to understand the pharmacokinetics and pharmacodynamics in order to provide patients with the safest and most effective analgesia. RECENT FINDINGS Tramadol is a centrally acting synthetic analgesic with a multimode of action used to help treat moderate to severe pain. Pharmacologically, the unique opioid acts as a serotonin-norepinephrine reuptake inhibitor, while its metabolite, O-desmethyltramadol, acts on the μ-opioid receptor. The analgesic strength of tramadol is about one-tenth that of morphine, making it a relatively safe analgesic. Potential side effects of tramadol include nausea, vomiting, constipation, pruritus, and respiratory depression; however, the severity of these symptoms is minimal compared to traditional opioids. Although some of the perioperative uses of tramadol may be rare, it is a pain management option to consider when alternatives have proved ineffective.

Abstract
PURPOSE OF REVIEW This review aims to summarize risks and disparities associated with the prevalence and treatment of opioid use disorder in the perioperative and long-term setting, as well as evidence-based treatment and prevention targeted toward specific vulnerable populations. RECENT FINDING There are significant demographic disparities in pain management and development and management of OUD in the chronic and surgical setting. While White patients traditionally receive more pain management, they are also at higher risk of developing OUD. Hispanic and Latin populations have the largest proportion of youth with OUD and often lack culturally appropriate translation services that allow for effective treatment. Native Americans have the second highest rate of OUD and often receive care in communities and healthcare settings that lack funding and resources to combat OUD. African Americans tend to suffer from the criminalization of OUD and are less able to seek treatment due to this, and furthermore, often lack community services that would benefit them. Additional vulnerable populations include homeless individuals that lack access to healthcare or health insurance. In addition, incarcerated individuals often lack access to naloxone and suffer from high rates of fatal overdose soon after being released to the community. People in rural settings lack needle-exchange programs and community-based interventions/support groups. Patients in the perioperative setting lack standard screening and pain management protocols. Interventions targeted toward each appropriate group can help decrease the rate of OUD and improve its treatment, and overarching interventions such as protocols, targeted funding, education and regulation can combat OUD for all populations.

Abstract
Introduction The management of pain and anxiety remains a challenge in the intensive care unit. By distracting patients, virtual reality (VR) may have a role in painful procedures. We compared VR vs. an inhaled equimolar mixture of N2O and O2 (Kalinox®) for pain and anxiety management during the removal of chest drains after cardiac surgery. Methods Prospective, non-inferiority, open-label study. Patients were randomized, for Kalinox® or VR session during drain removal. The analgesia/nociception index (ANI) was monitored during the procedure for objective assessment of pain and anxiety. The primary endpoint was the ΔANI (ANImin − ANI0) during the procedure, based on ANIm (average on 4 min). We prespecified VR as non-inferior to Kalinox® with a margin of 3 points. Self-reported pain and anxiety were also analysed using numeric rate scale (NRS). Results 200 patients were included, 99 in the VR group and 101 in the Kalinox® group; 90 patients were analysed in both groups in per-protocol analysis. The median age was 68.0 years [60.0–74.8]. The ΔANI was − 15.1 ± 12.9 in the Kalinox® group and − 15.7 ± 11.6 in the VR group (NS). The mean difference was, therefore, − 0.6 [− 3.6 to 2.4], including the non-inferiority margin of 3. Patients in the VR group had a significantly higher pain NRS scale immediately after the drain removal, 5.0 [3.0–7.0] vs. 3.0 [2.0–6.0], p = 0.009, but no difference 10 min after. NRS of anxiety did not differ between the two groups. Conclusion Based on the ANI, the current study showed that VR did not reach the statistical requirements for a proven non-inferiority vs. Kalinox® in managing pain and anxiety during chest drain removal. Moreover, VR was less effective based on NRS. More studies are needed to determine if VR might have a place in the overall approach to pain and anxiety in intensive care units.

Cancer survivorship and its association with perioperative opioid use for minor non-cancer surgery. Support Care Cancer 2020; 28:5763-5770.

Abstract
PURPOSE Reducing high-risk prescription opioid use after surgery has become a key strategy in mitigating the opioid crisis. Yet, despite their vulnerabilities, we know little about how cancer survivors use opioids for non-cancer perioperative pain compared to those with no history of cancer. The purpose was to examine the association of cancer survivorship with the likelihood of receiving perioperative opioid therapy for non-cancer minor surgery. METHODS Using 2007-2014 SEER-Medicare data for breast, colorectal, prostate, and non-cancer populations, we conducted retrospective cohort study of opioid-naïve Medicare beneficiaries who underwent one of six common minor non-cancer surgeries. Modified Poisson regression estimated the relative risk of receiving a perioperative opioid prescription associated with cancer survivorship compared to no history of cancer. Stabilized inverse probability of treatment weights were used to balance measurable covariates between cohorts. RESULTS We included 1486 opioid-naïve older adult cancer survivors and 3682 opioid-naïve non-cancer controls. Cancer survivorship was associated with a 5% lower risk of receiving a perioperative opioid prescription (95% confidence interval: 0.89, 1.00; p = 0.06) compared to no history of cancer. Cancer survivorship was not associated with the extent of perioperative opioid exposure. CONCLUSION Cancer survivors were slightly less likely to receive opioid therapy for non-cancer perioperative pain than those without a history of cancer. It is unclear if this reflects a reduced risk of opioid-related harms for cancer survivors or avoidance of appropriate perioperative pain therapy. Further examination of cancer survivors' experiences with and attitudes about opioids may inform improvements to non-cancer pain management for cancer survivors.

Abstract
Introduction The use of analgesics for the treatment of post-operative pain is common, however, such medications are known to have potential side effects. These undesirable secondary effects can have an important impact on patients and impede their recovery. Objectives A review of the literature was conducted in order to gain a better understanding of the challenges confronted by pediatric patients in the acute post-operative period in terms of the side effects of analgesics. Methods An online search of keywords (pediatric, analgesic, pain medication, side effects, adverse effects, nausea and vomiting, post-operative, post-discharge, self-care, self-management, management, self-care strategies, patient expectations, patient concerns and education) using PubMed, Medline and Scopus databases, and using the snowballing method of reference tracking was conducted. Results A total of 10 studies (N = 10, 871 participants) published between 1990 and 2019 were reviewed. Common side effects experienced by patients were nausea, vomiting, and pruritus. Patients' parents reported having many concerns about analgesic use and reported a lack of knowledge on pain medications and side-effect management. Conclusion Areas of improvement in clinical practice include providing the patient and their parents with more information about the post-operative period, analgesic use, and side effects as well as prescribing appropriate treatments to alleviate side effects. This review reveals a lack of qualitative data on pain management and related undesired side effects in pediatric patients having undergone inpatient surgery in addition to the consequences on patients' daily living and on the self-care strategies they engage in to attenuate such effects.

Abstract
Background Adolescent idiopathic scoliosis (AIS) has been associated with diminished postural stability and a greater prevalence of back pain. Currently, the literature is lacking information on the effect of spinal fusion on both postural stability and its association with back pain. Our objectives were to evaluate the postsurgical effect of spinal morphological changes on static standing balance and assess the influence of these alterations on reported pain throughout the perioperative period. Methods Twenty consecutive AIS patients schedule to undergo spinal fusion surgery were recruited and followed prospectively at the Shriners Hospitals for Children-Canada. Data was collected at the preoperative, 6 weeks and 6 months postoperative visits. Spinal morphology data was collected through 3D reconstructed simultaneous standing biplanar radiographs using the SterEOS software. Postural balance was assessed through Moticon© sensor insoles and analyzed through their software. The data was simultaneously collected as part of the Global Biomechanical and morphological Assessment. Pain was evaluated through self-reported questionnaires. Results Morphological curve parameters were significantly reduced after surgery. Balance parameters did not change significantly throughout the perioperative period with the exception of the Center of Pressure of the left foot medial/lateral transient shift (P = 0.017) at 6 weeks. Of note, preoperative balance parameters were associated with the degree of right thoracic Cobb angles (P = 0.029 R = 0.528). Pain scores significantly improved 6 weeks and 6 months after the surgery. Pain intensity diminished in the thoracic and lumbar spine but worsen in the neck region at the 6 weeks and 6 months postoperative time points (P = 0.044). Greater residual Cobb angle difference between Mid thoracic and Thoracolumbar/Lumbar curves was associated with greater pain severity at 6 weeks postop (P < 0.005). In addition, greater residual thoracic deformity was associated with significant pain severity 6 months after surgery (P < 0.05). Conclusions Improved spinal morphology of postsurgical AIS patients has no significant impact on their static standing balance. Suggesting that other factors apart from the spinal morphology may contribute to AIS patients’ balance during stance. Although balance did not influence pain severity, spinal morphology and its correction appear to have influenced the intensity and location of back pain.

INTERVENTIONS Subjects were randomized to receive a preoperative regimen of acetaminophen, celecoxib, and gabapentin versus acetaminophen and celecoxib alone. MEASUREMENTS AND MAIN RESULTS The primary outcome assessed was the total amount of narcotics used at 24 hours after surgery. Secondary outcomes included adverse effects from gabapentin use, total narcotics used, and pain scores at 2 weeks after surgery. A total of 129 women were randomized and eligible for analysis in the gabapentin study arm (n = 68) or the control arm (n = 61). Demographic characteristics and surgical details were similar between groups. Narcotics used at 24 hours after surgery totaling 168 versus 161 oral morphine milligram equivalents in the gabapentin and control groups, respectively, did not significantly differ between groups (p = .60). Total narcotics used and pain scores at 2 weeks after surgery and the rates of adverse effects from gabapentin were also similar between study arms. CONCLUSION Single-dose, preoperative gabapentin for women undergoing benign MIH does not reduce total opioid use 24 hours after surgery.

Decreased pain tolerance before surgery and increased postoperative narcotic requirements in abstinent tobacco smokers. Addict Behav 2018; 78:9-14. [PMID: 29121531 DOI: 10.1016/j.addbeh.2017.10.024] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2017] [Revised: 10/16/2017] [Accepted: 10/27/2017] [Indexed: 01/27/2023]
Abstract
INTRODUCTION The clinical influence of smoking cessation on pain tolerance before surgery and postoperative pain perception is not fully understood. This clinical study investigated the effect of smoking cessation on pain threshold during the perioperative period in patients undergoing hepatic resection. METHODS We enrolled 148 male patients (68 non-smokers and 80 abstinent smokers) who underwent hepatic resection and received postoperative patient-controlled intravenous analgesia. Patients were tested for preoperative pain thresholds in response to electrical stimuli. We recorded the cumulative amount of extra morphine equivalent required during the first 48h after surgery. Pain intensity was evaluated at 1h, 6h, 24h and 48h after surgery using the visual analogue scale (VAS). Additionally, button-pressing consumption was recorded by a patient-controlled analgesia (PCA) pump. RESULTS The groups did not differ with respect to baseline clinical characteristics. Compared with non-smokers, abstinent smokers exhibited lower pain thresholds before surgery and demanded a larger quantity of extra morphine equivalent during the first 48h after surgery. Abstinent smokers also exhibited more severe postoperative pain than non-smokers. Postoperative complications, such as nausea, vomiting, dizziness, sedation, and respiratory depression, did not significantly differ between the two groups. CONCLUSIONS In this study, smokers deprived of cigarettes exhibited decreased pain tolerance before surgery and required a larger quantity of postoperative extra morphine equivalent than non-smokers. Health care providers must be aware of the potential for increased narcotic requirements in smokers.

Interpersonal behavior in anticipation of pain: a naturalistic study of behavioral mimicry prior to surgery. Pain Rep 2018; 2:e605. [PMID: 29392220 PMCID: PMC5741360 DOI: 10.1097/pr9.0000000000000605] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2016] [Revised: 04/12/2017] [Accepted: 05/02/2017] [Indexed: 11/26/2022] Open
Abstract
Current and anticipated pain relate to mimicry behavior in divergent ways, which may bear upon the elicitation of social support during the experience of pain. Introduction: Social relationships facilitate coping with pain, but research suggests that it may be difficult to galvanize social support during an episode of acute pain. Objectives: The current research examined whether social connections are optimized in the anticipation of pain by observing patients' mimicry of an interaction partner prior to surgery. We hypothesized that when controlling for their current experience of pain, patients' anticipation of pain would be associated with greater mimicry of an interaction partner. Methods: Sixty-five patients were interviewed in the waiting room of a maxillofacial surgery unit prior to the removal of an impacted wisdom tooth. Patients' spontaneous mimicry of an interviewer was observed. Patients then rated the quality and intensity of their anticipated pain, as well as the intensity of their current pain and their affective distress. Results: Anticipated pain, current pain, and affective distress were positively correlated. Current pain was associated with less frequent mimicry of an interaction partner. The zero-order correlation between anticipated pain and mimicry did not reach conventional levels of significance; however, when controlling for current pain, anticipated pain predicted more frequent mimicry of an interaction partner. The relationship between anticipated pain and mimicry was not explained by affective distress. Conclusion: This is the first study to demonstrate that anticipated and current pain relate to behavioral mimicry in divergent ways. Further research is needed to investigate whether the current pattern of results generalizes to other interpersonal behaviors that facilitate social bonds.

Preoperative Norepinephrine Levels in Cerebrospinal Fluid and Plasma Correlate With Pain Intensity After Pediatric Spine Surgery. Spine Deform 2017; 5:325-333. [PMID: 28882350 DOI: 10.1016/j.jspd.2017.03.012] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/27/2016] [Revised: 12/21/2016] [Accepted: 03/19/2017] [Indexed: 11/20/2022]
Abstract
PURPOSE Catecholamines were found to be involved in descending pain modulation and associated with perioperative pain. The purpose of the present study was to investigate the relationship between preoperative concentrations of catecholamines and postoperative pain intensity of pediatric patients. METHODS Fifty adolescents with idiopathic scoliosis scheduled for elective spinal fusion surgery were enrolled in this prospective cohort study. Preoperative plasma and cerebrospinal fluid (CSF) samples were collected and analyzed by mass spectrometry. Pain intensity was assessed during the acute postoperative period and in the intermediate period. RESULTS Preoperative plasma concentrations of norepinephrine (NE) and normetanephrine (NME), as well as the CSF concentration of NE, were significantly correlated with the presence of pain six weeks after surgery (r = 0.48, 0.50, and 0.50, respectively; p < .002). We also found that preoperative NE levels in CSF were significantly higher in patients reporting moderate to severe pain intensity than in patients with mild pain during the first day following surgery (0.268 ± 0.29 ng/mL vs. 0.121 ± 0.074 ng/mL, p = .01), as well as between patients reporting pain and painless patients at 6 weeks postsurgery (0.274 ± 0.282 ng/mL vs. 0.103 ± 0.046 ng/mL respectively, U = 69.5, p = .002). CONCLUSIONS These results support the potential role of catecholamine levels in predicting postoperative pain intensity.

Preoperative Distress Factors Predicting Postoperative Pain in Adolescents Undergoing Surgery: A Preliminary Study. J Pediatr Health Care 2017; 31:5-15. [PMID: 26852092 DOI: 10.1016/j.pedhc.2015.12.008] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2015] [Revised: 12/21/2015] [Accepted: 12/30/2015] [Indexed: 11/22/2022]
Abstract
The purpose of this study was to determine if preoperative distress factors could be used as predictors of postoperative pain in adolescents scheduled for spinal fusion surgery. Patients reporting the presence of pain before surgery reported greater pain intensity at postoperative day (POD) 1 (p = .033), POD 2 (p = .008) and at follow-up 6 weeks after surgery (p = .0001). Preoperative trait anxiety was associated with pain intensity before surgery (p = .002) but not with postoperative pain intensity (p > .05). Salivary cortisol concentrations did not differentiate between anxious and nonanxious patients based on anxiety trait (p = .21) and was not associated with postoperative pain intensity (p > .05). These findings suggest that preoperative distress factors do not predict postoperative pain intensity in the acute and intermediate period. The presence of preoperative pain was the best predictor of postoperative pain intensity, suggesting that preoperative pain assessment will identify patients at an elevated risk for intense postoperative pain.

Tolerance and efficacy of a polyamine-deficient diet for the treatment of perioperative pain. Nutrition 2016; 36:33-40. [PMID: 28336105 DOI: 10.1016/j.nut.2016.02.018] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2015] [Revised: 02/07/2016] [Accepted: 02/21/2016] [Indexed: 11/21/2022]
Abstract
BACKGROUND Polyamines have been identified as pain agonists and interact with N-methyl-D-aspartate receptors. A prospective, randomized, multicenter, and blinded phase II clinical trial was conducted to evaluate a polyamine-deficient diet for the treatment of perioperative pain in patients during spinal surgery. METHODS All analyses followed the intention-to-treat principle. The trial was designed to evaluate the dose-ranging effect of a low polyamine diet with respect to a total (group 1) or partial (group 2) polyamine diet on perioperative pain (7 d before and 5 d after surgery). Pain (numerical scale at rest and motion), quality of life questionnaires (Brief Pain Inventory, EIFEL questionnaire, and Short Form-12 acute questionnaire), and tolerance of and compliance with the nutritional program were measured. RESULTS Compliance (preoperatively: 100% in group 1 and 83% in group 2; postoperatively: 83% in group 1 and 71% in group 2) and tolerance were good. After 7 d following the diet before surgery, decreased pain was observed in group 1 whereas no effect was observed in group 2 (P = 0.144). This analgesic effect became significant in group 1 in the subgroup of patients with initial high levels of pain (NS ≥ 4) at rest (P = 0.03) and during motion (P = 0.011). Quality of life was significantly improved in group 1 (P = 0.0465). In the postoperative period, pain was significantly decreased in group 1 compared to group 2 at rest (P = 0.022) and during motion (P = 0.029). The effect was significantly better on patients with higher initial pain both at rest (P = 0.013) and during motion (P = 0.005) in group 1 compared to group 2. CONCLUSION Suppression of polyamines from the diet offers a nutrition-based treatment option for perioperative pain reduction independent of and complementary to typical analgesic approaches.

Development and initial evaluation of a point-of-care educational app on medical topics in orthogeriatrics. Arch Orthop Trauma Surg 2016; 136:65-73. [PMID: 26646844 PMCID: PMC4706575 DOI: 10.1007/s00402-015-2366-8] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/13/2015] [Indexed: 12/18/2022]
Abstract
INTRODUCTION Research by AOTrauma's orthogeriatrics education taskforce identified ongoing educational needs for surgeons and trainees worldwide regarding the medical management of older adults with a fracture. To address practicing surgeons' preference for increased use of mobile learning, a point-of-care educational app was planned by a committee of experienced faculty. The goals were to deliver the app to surgeons, trainees, and other healthcare professionals, to measure usage, and to evaluate the impact on patient care. MATERIALS AND METHODS The committee of geriatricians and surgeons designed and developed four modules on osteoporosis, delirium, anticoagulation, and pain based on published evidence and the content was programmed into mobile app formats. A registration form was integrated and a 14-question online evaluation survey was administered to users. RESULTS The AOTrauma Orthogeriatrics app was installed by 17,839 users worldwide between September 2014 and October 2015: Android smartphones (44%), iPhones (32%), iPads (15%), Android tablets (9%). 920 users registered and 100 completed the online evaluation: orthopedic/trauma surgeons (67%), residents/fellows (20%), and other professionals (13%). Ratings for all aspects were 4 or higher on a 1-5 Likert scale (5 = Excellent). 80% of evaluation respondents found the answer to their question or educational need on their last visit, and 26 of 55 respondents (47%) reported making a change in an aspect of their management of patients as a result of their learning from the app. CONCLUSION The orthogeriatrics app reached its intended audiences and was rated highly as a method of providing education to help improve patient care. Content input by experienced faculty and app improvements based on user feedback were key contributors to successful implementation.
