NCT ID: NCT06040307 Completed - Pain, Postoperative Clinical Trials

Guiding Opioid Administration in Patients With Regional Anesthesia

GORA
Start date: December 18, 2023
Phase: N/A
Study type: Interventional

General anesthesia is a combination of hypnotic drugs to achieve unconsciousness and opioid analgesics to ensure antinociception. An alternative approach to the intraoperative administration of high potency opioids in order to achieve antinociception during surgery is combining a general anesthesia with a regional anesthesia. Modern general anesthesia aims to treat nociception induced by surgical stimulation while avoiding an overdose of opioid analgesics and reducing side-effects of opioid administration. Quality and safety of general anesthesia are of major clinical importance and can be improved by adjusting the opioid analgesics to the optimal individual dose needed. In the current clinical practice, the opioid dosage is usually chosen by clinical judgment. Recently different monitoring devices estimating the effect of nociception during unconsciousness have become commercially available. One of the first commercially available nociception indices was the Surgical Pleth Index (SPI) derived by the CARESCAPEā„¢B650 patient monitor (GE Healthcare). Until today, it remains unknown whether guiding sufentanil administration by SPI monitoring affects the administered amount of intraoperative and postoperative opioid, immediate postoperative pain in the postanesthesia care unit (PACU) and the quality of postoperative recovery in patients with a combination of general and regional anesthesia. This study aims to investigate whether guiding sufentanil administration by SPI monitoring - compared to routine care - reduces intraoperative sufentanil consumption in patients having trauma and orthopaedic surgery with a combination of general and regional anesthesia.

NCT ID: NCT05687175 Completed - Clinical trials for Neuropathic Pain, Nociceptive Pain

Translation and Validation of Malay Version of painDETECT Questionnaire

PDQM
Start date: February 1, 2020
Phase:
Study type: Observational

The translation and cultural adaptation process of the English version of PDQ will be performed based on international guidelines. Subsequently, patients with neuropathic and nociceptive pain based on clinician's diagnoses will be recruited to complete three-type numeric rating scale (NRS) of pain followed by PDQ-M and SF-36 questionnaire. Patients' socio-demographic data and clinical characteristics will be reported using frequency for categorical variables and mean with standard deviation for continuous variables. Normality will be assessed using Shapiro Wilk test and histograms for continuous variables. Data will be compared between groups using chi-square test (for categorical variables) and t-test or Mann-Whitney's U test (for continuous variables). Suitability of PDQ-M data for factor analysis will be verified using the Bartlett's test of sphericity and the Kaiser-Mayer-Olkin (KMO) measure of sampling adequacy. Parallel analysis will performed to obtain the suitable factors. Construct validity will be investigated by exploratory factorial analysis (EFA) with varimax rotation. A factor loading of >0.40 will be used to determine the items for each factor. The internal consistency of the questionnaire will be assessed using Cronbach's alpha test. A p value of <0.05 is taken as statistically significant.

NCT ID: NCT05589935 Completed - Pain Clinical Trials

Radicle Relief 1: A Study of Health and Wellness Products on Pain and Other Health Outcomes

Start date: November 22, 2022
Phase: N/A
Study type: Interventional

A randomized, blinded, placebo-controlled study assessing the impact of health and wellness products on pain and other health outcomes

NCT ID: NCT05579106 Completed - Nociceptive Pain Clinical Trials

Nociception and BIS Level Monitoring in COVID-19 Patients in the Intensive Care Unit

NEMO
Start date: November 8, 2022
Phase:
Study type: Observational

Pain (nociception), stress and discomfort are difficult to detect in sedated and intubated patients during mechanical ventilation. In order to improve this several nociception level monitors (NOL) were developed that objectively track nociception in sedated or anesthetized patients. Earlier studies showed that for sedated and intubated patients in the operating room, using such monitors is beneficial in reducing stress hormones and post operative pain scores. In this study the investigators aim to observe whether the NOL could be equally beneficial in managing nociception in sedated and intubated ICU patients.

NCT ID: NCT05391568 Completed - Neck Pain Clinical Trials

Effects of Dry Needling on Autonomic Nervous System and Nociceptive Pain Processing in Neck Pain

Start date: May 31, 2022
Phase: N/A
Study type: Interventional

Pain in the neck is a musculoskeletal disorder that affects many individuals. Dry needling has shown an effective technique for the treatment of shoulder and neck disorders. The mechanisms of action of the dry needling are not well-known. This study aims to evaluate the effects of dry needling in the upper trapezius on the autonomic nervous system and nociceptive pain processing in patients with non-specific neck pain. Hypothesis: Dry needling applied in the upper trapezius in patients with non-specific neck pain produced greater activation of the autonomic nervous system and nociceptive pain processing than sham dry needling.

NCT ID: NCT05127200 Completed - Nociceptive Pain Clinical Trials

Cervical Neuromodulation and Nociceptive Processing

MICROVOLT
Start date: May 24, 2022
Phase: N/A
Study type: Interventional

Several studies have demonstrated that direct currents delivered through the skin at the level of the lumbar spinal cord can influence spinal cord function. In human volunteers, anodal lumbar transcutaneous spinal direct current stimulation (tsDCS) alters spinal processing of nociceptive inputs. Whether cervical tsDCS is able to do the same is less well known.

NCT ID: NCT05049577 Completed - Analgesia Clinical Trials

Preanesthetic Analgesia/Nociception Index (ANI) and Propofol Injection Pain

Start date: April 1, 2023
Phase: N/A
Study type: Interventional

Recently, Analgesia Nociception Index (ANI) has been evaluated for objectively measuring peri-operative pain and to guide intra-operative opioid administration during various surgeries. Propofol injection pain (PIP) is a common problem and can be very distressing to the patient.

NCT ID: NCT04925336 Completed - Healthy Clinical Trials

Cerebral and Autonomic Responses to Pain in Healthy Humans

ALGOBLOC-1
Start date: April 6, 2021
Phase: N/A
Study type: Interventional

Evaluating the intraoperative pain is a major challenge for the anesthesia team. During anesthesia, changes in heart rate and blood pressure are interpreted qualitatively to evaluate the sympathetic response to nociceptive stimulation or the adaptation of analgesia during surgery. The new nociception monitors under development quantitatively explore other variables dependent on sympathetic activity or sympathetic / parasympathetic balance, such as the pulse wave amplitude measurement (Surgical Pleth Index (SPI index)), the pupil dilation reflex, respiratory sinus arrhythmia (ANI, Analgesia Nociception Index), or skin conductance index. Taken independently, these tools provide an assessment of nociception based on variations in the autonomic system, more robust than simply observing heart rate or blood pressure raw values. However, the relationship between variations in the neurovegetative system and pain can be compromised by various factors or intraoperative events such as hypovolemia, bleeding, certain sympathomimetic or sympatholytic treatments, the hypnosis depth, ventilation variation, fast filling, or body temperature. Moreover, investigators do not know the delay between the application of the painful stimulus and the observation of the variation of the different neurovegetative variables. This constitutes a limit of the practitioners' confidence in these monitoring tools. The nociception transmission pathways of to the vegetative centers and cortical areas are complex. Investigators hypothesis is that neurovegetative variations in response to nociceptive stimulation are not always associated with a cortical somatosensory response. In this project investigators investigate the relation between cortical (EEG) and vegetative reactions to acute and tonic nociceptive stimuli, as a preliminary step to apply these procedures to assess intraoperative reactions to nociceptive procedures in anesthetized patients.

NCT ID: NCT04907162 Completed - Healthy Clinical Trials

Musculoskeletal Nociceptive Pain in Participants With Neuromuscular Disorders

Start date: April 15, 2021
Phase:
Study type: Observational

The primary aim is to characterize the prevalence, severity and quality of musculoskeletal nociceptive pain in adult patients with neuromuscular disorders (NMD). The secondary objectives are to evaluate whether severity and distribution of muscle pain is associated with muscle function, and to assess whether muscle pain is associated with alterations of muscle elasticity and muscle stiffness. Results of patients with neuromuscular disorders will be compared to age- and gender-matched healthy volunteers. Approx. 70 patients with neuromuscular disorders and 20 healthy volunteers will be enrolled, including patients with the following neuromuscular disorders: histologically confirmed inclusion body myositis (IBM), genetically confirmed late-onset Pompe disease (LOPD), genetically confirmed spinal muscular atrophy type 3 (SMA3), genetically confirmed facio-scapulo-humeral muscle dystrophy (FSHD), genetically confirmed myotonic dystrophy type 1 or type 2 (DM1, DM2). The duration of patient recruitment will be around 12 months.

NCT ID: NCT04567160 Completed - Anesthesia Clinical Trials

NOL Index to Compare the Intraoperative Analgesic Effect of Propofol Versus Sevoflurane

PROSEVNOL
Start date: October 1, 2020
Phase: Phase 4
Study type: Interventional

The purpose of this prospective randomized controlled study is to compare the analgesic properties of propofol and sevoflurane using variation of the NOL index and standard monitoring (Heart Rate and Mean Arterial Blood Pressure) when patients under general anaesthesia with either agents are subjected to a standardized painful stimulus (a tetanic stimulation over the ulnar nerve at 70 mA, 100 Hz for 30 seconds).
