Filter by: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.
The aim of this study will be to investigate the effect of a continuous infusion of low dose esmolol on intraoperative and postoperative opioid consumption, as well as on postoperative recovery and chronic pain
A study to investigate the role of F-18 sodium fluoride in localizing the pain generator in participants with chronic nociceptive musculoskeletal low back ache and to study the use of PET/CT guided robotic arm assisted injection for targeted injection of a combination of corticosteroid and local anesthetic for pain palliation.
Due to their underlying pathology and the necessary complicated procedures to which they are exposed, patients in the intensive care unit experience varying degrees of pain at some point in their evolution. Evidence has established short-term and long-term negative consequences of unresolved pain or excessive analgesic sedation. However, pain assessment or adequate nociceptive monitoring remains a significant challenge, especially in non-communicative patients under deep sedation, who urgently need to expand and improve current tools. Pain assessment in critically ill patients is challenging; limitations in their ability to communicate (neurocognitive deficit, use of endotracheal tube) or altered consciousness (deep sedation) make them unable to self-report their pain with standard pain scales. The Behavioral Pain Scale (BPS) and the Critical-Care Pain Observation Tool (CPOT) are the pain assessment tools with the best performance and reliability for patients in these conditions. Different technologies are used to monitor nociceptive responses caused by surgical stress in patients under general anesthesia that together with the clinical evaluation, manage to keep patients in the best analgesic conditions, improving the post-surgical prognosis. In particular, the NOL® nociceptive index (Medasense, Ramat Gan, Israel) is a multiparametric detection of nociception/pain, delivering a dimensionless score (0 -100) calculated through an algorithm (patented) and based on the registry of four biometric sensors (photoplethysmography, galvanic skin response, temperature, and accelerometer). NOL index value between 10-25 is the most appropriate for maintaining analgesia during general anesthesia. The ease and low invasiveness of this system (all sensors are implemented in a finger clip, similar to an oxygen saturation monitor) may allow its potential use in the context of intensive care unit patients. Some studies have recently been published that highlight the possible usefulness of the NOL® index in critically ill patients. However, in these studies, the assessment of nociception was limited to acute nociceptive procedures only.
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.
Assessing pain in the adult intensive care unit (ICU) is challenging because many patients are unable to communicate due to mechanical ventilation and sedation. Therefore, it is necessary to have alternative methods to assess pain in this vulnerable patient population. In this project, the use of a multi-parameter technology (i.e., the Nociception Level (NOL) index) will be tested for pain assessment in ICU adults. The NOL index is a value from 0 to 100 obtained by calculating different parameters (e.g., pulse, skin temperature) captured through a small probe placed on the patient's finger. The NOL was initially developed for assessing nociception, pain and analgesia in anesthetized patients undergoing surgery, and its use in the ICU is new. The NOL's use before, during and after standard care procedures known to be painful (e.g., tube or drain removal, suctioning of secretions through the endotracheal tube) and non-painful (e.g., cuff inflation to measure blood pressure, soft touch) in ICU adults. The NOL will be monitored in three groups: a) patients able to communicate so they can self-report their pain (gold standard criterion) and express behaviors, b) patients unable to communicate but express behaviors (reference criterion), and c) patients unable to communicate and to express behaviors. In the first group, patients will be asked to self-report their pain and procedural distress on a 0 to 10 scale. In the first and second group, patients will be assessed for pain using a standardized behavioral scale which will be completed by trained research staff. In the third group, only the NOL will be monitored. Analgesic and sedative medication administered to patients will also be documented from medical charts. The ability of the NOL to detect pain based on self-reports of pain and behavioral scores, and its ability to discriminate between painful and non-painful procedures will be examined. If found to be useful, the NOL could be used as an alternative measure of pain and improve its recognition and treatment in vulnerable ICU patients.
The aim of this study will be to investigate the effect of an opioid-free anesthesia regimen with a mixture of dexmedetomidine-lidocaine-ketamine in the same syringe versus fentanyl analgesia in elective thyroidectomies. Recovery parameters and nociception levels throughout the operation will be evaluated
Traditionally, hemodynamic response e.g. pulse and blood pressure are used to evaluate pain in humans who are anesthetized. These values, however, can be affected by factors other than pain response . In this observational study, different types of digital methods are used that can distinguish signs of pain. However, the study aim to collect data and correlate in between different methods to ensure its reliability.
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.
The aim of the study is to compare the analgesic nociception index (ANI), which is used to determine the dose of analgesic agent needed in the intraoperative period, with the conventional method in patients with erector spinae block who underwent gynecological surgery under general anesthesia.
