Postoperative pain management has an important role in anesthesia practice. In order to ensure postoperative patient comfort, postoperative rehabilitation should start early and be managed effectively1. It is known that if adequate analgesia is not provided before the patient wakes up, the severity of pain and the total opioid consumption increases. This increased opioid use causes complications such as nausea, vomiting, constipation, increased sleepiness and respiratory depression2. For this reason, the provision of adequate analgesia before the patient is awakened from general anesthesia has an important place in the process. Measurement of pain has different characteristics in patients under sedation or general anesthesia compared to conscious patients. However, since it is not possible for the patient to define pain under general anesthesia, different measurement and evaluation methods are needed. In order to monitor the intraoperative balance between nociception and antinociception, several non-invasive methods with different physiological approaches have been researched and made available for use in the last decade. The aim of these methods is individualize the intraoperative and postoperative opioid dose3. In this context, it has been suggested that the Surgical Pleth Index (SPI) method can be used in the evaluation of the analgesic component of anesthesia.

NCT06466941
The goal of this observational study is to learn about how regional anesthesia (numbing medication) affects pain in patients with different psychosocial phenotypes such as different levels of concern about pain, sleep issues, and anxiety, who are having surgery. The main questions are: 1. Do psychosocial factors such as concerns about pain, sleep, anxiety affect the effectiveness of regional anesthesia? 2. Do psychosocial factors and regional anesthesia affect the amount of opioids used after surgery? 3. Do psychosocial factors and regional anesthesia affect development of chronic postsurgical pain?

Almost 30% of painful patients in emergency departments (ED) describe their pain as severe (i.e. a Verbal Numerical Rating Score VNRS ≥ 6 on a scale ranging from 0 to 10). The management of such severe pain needs to be rapid and safe, and for this purpose intravenous (IV) morphine titration is still the gold-standard. However, morphine titration takes up considerable caregiver time, as patients need to be monitored and treated progressively with small quantities of morphine every 5 minutes until analgesia. This is sometimes difficult to reconcile with a saturating flow of patients, and overcrowding in ED is proven to significantly delay time-to-analgesia, and even lead to deleterious under-treatment. Finally, the opioid crisis is a major concern, explaining why strategies are being advocated to develop other ways of managing severe acute pain in the ED and to limit the use of opioids. Recent studies show that ketamine administered in small IV doses ("low-dose" ketamine LDK: 0.2 to 0.3 mg/kg) possesses potent analgesic activity as well as interesting anti-hyperalgesic and anti-allodynic properties. Compared with morphine, LDK does not induce respiratory depression, but can sometimes induce disturbing psychodysleptic effects. These may include a sensation of unreality, fatigue, anxiety, dizziness or hallucinations. According to studies, 30-80% of LDK-treated patients experience psychodysleptic effects. However, two recent studies suggest that slow IV injections of LDK (over 10 minutes) may improve patient tolerance, although these slow infusions do not totally reduce this discomfort. Pharmacologically, ketamine is a racemic mixture of 2 isomers: esketamine S(+), which is dextrorotatory, and arketamine R(-), which is levorotatory. In recent years, a new formulation containing only esketamine has been made available to hospitals in some northern European countries, and more recently in France. Esketamine appears to have twice the analgesic efficacy of racemic ketamine, and studies on healthy volunteers or in peri-operative settings suggest that it is also better tolerated psychologically than ketamine. For the moment, however, scientific data are lacking, and no comparative trial has yet been conducted in the ED setting. The investigators plan to conduct in their ED a prospective, single-center, randomized, double-blind study aiming to compare the tolerance and efficacy of esketamine versus racemic LDK in patients presenting with severe acute pain (VNRS ≥ 6/10).
NCT07290881
The primary aim of this study is to compare two postoperative analgesia techniques used in patients undergoing inguinal hernia surgery-(1) the anterior iliac block and (2) the ilioinguinal/iliohypogastric block-in terms of postoperative analgesia duration and patient satisfaction. Effective postoperative analgesia in inguinal hernia surgery is crucial for improving patient comfort and reducing opioid consumption. Although ilioinguinal and iliohypogastric nerve blocks are commonly used for this purpose, their relatively limited dermatomal coverage may result in inadequate analgesia in some cases. The recently described Anterior Iliac Block has been proposed as an alternative to conventional techniques, offering potentially wider neural spread and more effective postoperative pain control. However, the efficacy and safety of this novel block have not yet been sufficiently evaluated in the literature.

Pharmacogenomics (PGx) is the study of how genes affect a person's response to drugs. PGx testing for certain genes can help predict the risk of side effects or therapeutic failure from analgesics. Testing is not regularly performed in clinical practice due to long wait times for results and challenges with integrating test results in the electronic health record. Investigators leading this study hope to find out if providing surgeons with the ability to order a PGx test and electronically receive results with dosing recommendations will increase the use of these tests to guide analgesic choice and improve patient outcomes. This is a prospective, two-arm randomized implementation study. Eligible participants will be randomly assigned to receive genotype-guided analgesic selection (intervention arm) or usual care (control arm). Both cohorts will undergo pharmacogenetic testing at the time of consenting. The investigators will primarily measure the feasibility of using this test to guide analgesic selection.
NCT02799004
Pain is one of the most common complaints in emergency department (ED) and is still often poorly managed. A major prospective multicenter study reported that 74% of patients that had a pain complaint at ED triage are discharged in moderate to severe pain. Accordingly, physicians frequently prescribed analgesic after discharged for these patients, and opioid is given in 29% of ED visits involving pain complaints. However, few studies evaluate pain management after ED discharge: the frequency and length of opioids prescriptions, the opioids quantity taken by the patients, are the patients relieved and satisfied by these pain treatments, what are the adverse effects associated with the use of these medications, and what are the chances of developing addiction? The primary aim of this study is to determine the required minimal opioids prescription for patients treated for acute pain after being discharge from the ED. Secondary objectives include: 1) monitor the patients' adverse events during opioids treatment; 2) evaluate the patients' level of pain relief associated with their respective opioids treatment; 3) determine the patients' level of addiction following post-ED opioids treatments. The design of the project is a prospective observational cohort study. A cohort of consecutive ED patients aged 18 or more with an initial pain at triage of 4 or more and discharged from the ED in less than 48 hours with a prescription of opioid will be asked to participate in the study. Patients will be excluded if there is ongoing treatment for a pre-existing chronic pain condition or if they used opioid drugs in the past year. Research nurses will contact the patients by phone at three follow-up time points (1 week, 1 month, and 3 months). Follow-up phone interviews will evaluate pain intensity as well as pain treatment satisfaction (0-10 NRS), monitor adverse events, and investigate possible opioids addiction (SOWS: subjective opioid withdrawal scale). During these interviews, the nurses will also question the patients about their daily opioids usage and if they were relieved from pain. This study will provide the base for future guidelines regarding the prescription of opioids treatment for specific pathology encountered in ED. It will also give indications on how to adjust the treatments according to adverse events and the level of addiction experienced by patients.
NCT06795126
The aim of this study is to test the feasibility of using Little NIRVANA (augmented reality (AR)) for managing anxiety and pain for children 2-8 years old during hospital emergency peripheral intravenous (PIV) insertions. The investigators hypothesize that Little NIRVANA plus a numbing cream will reduce pain and anxiety for patients undergoing PIV placement in the emergency department (ED) when compared to the cream alone. It is anticipated that using the Little NIRVANA will not increase the ED length of stay, failed PIV placement attempts, or the need for additional intervention.

This is a Master Protocol Screening record. This study is comprised of three separate pharmacogenetic trials grouped into a single protocol due to similarities in the intervention, the hypotheses, and the trial design. The three trials are the Acute Pain Trial, the Chronic Pain Trial, and the Depression Trial. Participants can enroll in only one of the three trials. Each trial is listed individually on clinicaltrials.gov and includes "PRO00104948" within the Unique Protocol ID: PRO00104948\_A - Acute Pain Trial - NCT05966129 PRO00104948\_B - Chronic Pain Trial - NCT05966142 PRO00104948\_C - Depression Trial - NCT05966155 Acute Pain Trial: A prospective, multicenter, two arm randomized pragmatic trial. Participants meeting eligibility criteria will be randomly assigned to either immediate pharmacogenetic testing and genotype-guided post-surgical opioid therapy (Intervention arm) or standard care and pharmacogenetic testing after 6 months (Control arm). The investigators will test the hypothesis that pharmacogenetic testing and genotype guided pain management therapy improves pain control after surgery in participants who's body processes some pain medicines slower than normal. Chronic Pain Trial: A prospective, multicenter, two arm randomized pragmatic trial. Participants meeting eligibility criteria will be randomly assigned to either immediate pharmacogenetic testing and genotype-guided opioid therapy (Intervention arm) or standard care with 6-month delayed pharmacogenetic testing (Control arm). The investigators will test the hypothesis that pharmacogenetic testing and genotype guided pain therapy improves pain control after surgery in participants who's body processes some pain medicines slower than normal. Depression: A prospective, multicenter, two arm randomized pragmatic trial. Participants meeting eligibility criteria will be randomly assigned to either immediate pharmacogenetic testing and genotype-guided anti-depressant therapy (Intervention arm) or standard care with 6-month delayed pharmacogenetic testing (Control arm). The investigators will test the hypothesis that pharmacogenetic testing and genotype-guided anti-depressant therapy will reduce depression symptoms in participants who's body processes some anti-depressants faster or slower than normal.
NCT06854991
The objective of this study is to develop central nervous system (CNS) biomarkers of pain experienced during medical procedures and pain relief induced by Virtual Reality Pain Alleviation Therapy (VR-PAT). The study team plans to use innovative functional near-infrared spectroscopy (fNIRS) to identify and quantify the targeted CNS biomarkers. The ultimate goal of this project is to optimize the CNS biomarkers for predicting and/or monitoring response to virtual reality (VR)-based pain reduction approaches for pain management in clinical trials. 20 healthy children will be recruited for a 1-hour research visit where they will wear a blood pressure cuff to simulate pain and an fNIRS neuroimaging device while playing an immersive/engaging VR game, a passive VR video, and an iPad game.

Brachial plexus blocks (BPB) are commonly used to provide regional anaesthesia for patients undergoing distal radial fracture surgery. Distal radial (DR) fracture surgery is a commonly performed orthopaedic surgery and is usually associated with moderate postoperative pain. Poor postoperative pain control can impair rehabilitation, delay recovery and negatively impact outcomes after surgery. Liposomal bupivacaine (EXPAREL) is a multivesicular formulation of bupivacaine that allows rapid absorption and prolonged release of bupivacaine. Liposomal bupivacaine may provide prolonged analgesia for up to 72 hours after single injection and may therefore achieve greater analgesic efficacy compared to non-liposomal long-acting local anaesthetics. The addition of additive drugs such as dexmedetomidine to regional nerve blocks can also extend analgesia and improve postoperative pain. However, the effect of adding liposomal bupivacaine versus adding dexmedetomidine in regional nerve blocks is not known. In this project, the investigators propose to conduct a randomized controlled trial to investigate the effect of adding liposomal bupivacaine versus dexmedetomidine in the supraclavicular BPB for acute postoperative analgesia. The investigators will also assess longer term secondary outcomes including upper limb functional scores, chronic pain, and health related quality of life.
NCT07454083
The goal of this observational study is to evaluate the real-world effectiveness of an acupuncture-first stepped care pathway for pain management in adults aged 18 years and older receiving routine outpatient clinical care for non-cancer-related pain conditions. The primary purpose is to describe episode-based clinical outcomes and care utilization patterns as they occur in standard practice. The main questions it aims to answer are: * What proportion of completed pain episodes achieve a clinically meaningful improvement, defined as a ≥50% reduction in pain intensity (Numeric Rating Scale or Visual Analog Scale) within an episode treatment window of up to 8 acupuncture visits? * What are the visit utilization patterns, time to clinically meaningful improvement, and care escalation patterns within an acupuncture-first stepped care pathway in routine outpatient practice? There is no comparison group. This study does not introduce or test a new intervention. All care is delivered as part of standard clinical practice. Participants will: * Receive acupuncture treatment as part of routine outpatient care * Undergo routine pain assessments (NRS/VAS) at each clinical visit * Participate in standard clinical follow-up as determined by usual care practices No additional research-specific visits, procedures, questionnaires, or interventions are introduced. Data analyzed in this study are derived from routine clinical documentation systems and are de-identified prior to analysis.

This project is a single-site, five-arm, randomized controlled trial investigating whether providing patients in an orthopedic clinic waiting room psychoeducation about mindfulness impacts the degree of pain relief they experience during a mindfulness-based intervention.
NCT06779604
The aim of this study was to investigate the effect of dexmedetomidine and dexamethasone added during USG-guided infraclavicular block on block onset time, total block time and time to first analgesic need in patients undergoing upper extremity surgery.
NCT07422272
Pain is defined by the International Association for the Study of Pain as "an unpleasant sensory and emotional experience associated with, or resembling that associated with, actual or potential tissue damage." Low-Level Laser Therapy (LLLT) has gained attention as a safe, noninvasive intervention with analgesic and anti-inflammatory effects. This study examines whether a single session of LLLT can produce immediate changes in pain threshold and pain tolerance in healthy adults, compared to a sham laser control.

Adequate postoperative pain management, along with mobilization and early oral nutrition, is the foundation for optimal recovery after surgery. Unidimensional pain scales (Numerical Verbal Rating Scale - NRS, Visual Analogue Scale - VAS, Categorical Scale - CRS, Facial Pain Scale - FPS) do not adequately reflect a patient's actual analgesic needs. Basing analgesic treatment on the classic algorithm of administering opioids if pain is greater than 4 on the NRS, without considering functional impairment, has been shown to be a cause of overtreatment in surgical wards. The Functional Activity Score (FAS) is the simplest scale, designed for bedside application and geared toward therapeutic decision-making. R: Able to perform any activity; B: Pain prevents some activity; C: Unable to perform any activity. Given the need to standardize functional limitation when measuring postoperative pain, we propose the Pain and Functional Activity Scale (PFAS), which combines the NVA (Non-Visual Analogue Scale) with the Functional Activity Scale. Specifically, pain on movement would be recorded using the NVA in motion (NVAm), along with functional limitation (A, B, or C). The rescue analgesia treatment algorithm adapted to the PFAS would involve treating patients with pain greater than 4 on the NVA whenever it represents a severe limitation of their functional activity (C). In this study, we aim to evaluate whether there are significant differences in the proportion of patients who meet the criteria for needing rescue analgesia according to the NVA compared to the proportion of patients who meet the criteria for needing rescue analgesia established by the PFAS, during the 2-day postoperative period. To this end, an experimental, longitudinal, prospective, randomized, single-blind study for the data analyzer will be carried out, where a group that will receive rescue analgesia if VNS\>4 and another if VNSm\>4 + FAS C will be compared in the first two days of postoperative surgical patients of the surgeries selected in the EOXI of Vigo.

This study was conducted to evaluate the effectiveness of Quadratus Lumborum Type 1 and Type 2 blocks on postoperative acute pain in gynecological operations performed with a Pfannenstiel incision.
NCT07348523
The investigators aim to compare the postoperative analgesic efficacy of the classical erector spinae plane block and the modified erector spinae plane block in the management of postoperative analgesia after lumbar disc surgery.
NCT06968546
Pain is one of the most common reasons for children to attend emergency departments, particularly following traumatic injuries such as fractures, sprains, or contusions. Despite advances in medical care, severe acute pain in children is still sometimes inadequately treated. One important reason is that intravenous pain medication can be technically difficult, stressful, or delayed in paediatric patients. Intranasal drug administration, which involves spraying medication into the nose, offers a rapid and needle-free way to relieve pain and is increasingly used in paediatric emergency care. Two medications can be administered through this route: ketamine and sufentanil. Intranasal ketamine is already widely used in children for pain management. Sufentanil is a potent opioid analgesic commonly used in adults and in anaesthesia but has been much less studied in children when administered intranasally. The aim of this study is to compare the effectiveness and safety of intranasal sufentanil and intranasal ketamine in children aged 6 to 17 years who present to the emergency department with severe traumatic limb pain. Both medications will be given in addition to standard care, including the routine use of an oxygen-nitrous oxide gas mixture (MEOPA), which is commonly used to reduce pain and anxiety in children. Children who take part in the study will be randomly assigned to receive either intranasal sufentanil or intranasal ketamine. Pain levels will be assessed at regular time points after medication administration using age-appropriate pain scales. Sedation level and possible side effects will also be closely monitored for a short period following treatment. The hypothesis of this study is that intranasal sufentanil will provide greater pain relief than intranasal ketamine 30 minutes after administration, without increasing the risk of adverse effects, when both are used alongside standard emergency care. The results of this study are expected to improve knowledge about fast, effective, and non-invasive pain relief strategies for children in emergency settings and may help optimise future pain management protocols in paediatric emergency care.

Regional anesthesia techniques (or nerve blocks) are used to provide sensory blockade over the abdominal wall. The most established technique is thoracic epidural. This provides bilateral spread but is also associated with neuraxial complications, which has led to a decrease in clinical usage. The rectus sheath block (RSB) is an established regional anesthesia technique used to provide somatic analgesia to the midline anterior abdominal wall by depositing local anesthetic in the posterior rectus sheath, thereby targeting the terminal anterior branches of the lower thoracic intercostal nerves. The conventional approach involves placing the ultrasound (US) probe transversely across the rectus abdominis muscle and advancing the needle in-plane either lateral-to-medial or medial-to-lateral. While this technique achieves spread within the sheath, the cephalocaudal distribution of local anesthetic may be suboptimal, potentially limiting the extent of dermatomal coverage. A longitudinal probe orientation, with needle insertion from cephalad to caudad, may theoretically facilitate a more extensive cranio-caudal spread by aligning the injection axis with the anatomical fascial plane of the posterior rectus sheath. However, the relative efficacy of these two approaches has not been investigated in a controlled, comparative setting. Thus, this randomized, single-blinded trial aims to evaluate the dermatomal sensory distribution and ultrasound-assessed local anesthetic spread achieved by the transverse versus longitudinal in-plane approaches to ultrasound-guided RSB in healthy adult volunteers. To compare the dermatomal sensory block distribution, investigators will use dermatomal mapping with pinprick, and cold.
