Filter by:This study examine the effect of Parasternal Intercostal Nerve Blocks with local anesthetic on pain control in patients undergoing non-emergent cardiac surgery in a prospective controlled trial. Half of participants will receive General Anesthesia combined to parasternal block while the other half receive only General Anesthesia.
This study analyze the effect of Pericapsular Nerve Group (PENG) Block combined to wound infiltration for analgesia after elective hip replacement. Half of participants will receive a PENG Block combined with wound infiltration, while the other half will receive wound infiltration alone.
Volunteers will receive a weight-based opioid (remifentanil) infusion for 10 minutes. In the first run, serial pupillary measurements (pupillary unrest, pupil diameter) will be taken at baseline, and at 2.5-minute intervals during the infusion and a 25-minute recovery period afterwards. After a washout period, the experiment will be repeated in each subject (second run). The two runs differ only by presence versus absence of verbal interaction.
Inguinal hernia repair (IHR) is one of the most commonly performed operations in general surgery practice. Different pharmacological approaches and interfascial plane blocks are used to control postoperative pain. Erector spinae plane (ESP) block is a relatively new interfascial plane block which was reported to be effective in different types of surgeries. In this study, the primary aim is to assess the effect of ESP on recovery of patients following open IHR surgery.
Pain is common and can contribute to both psychological and physiological effects if not treated. Currently primary care paramedics have limited selections within their pain management tool box. This contributes to inadequate pain management. Methoxyflurane is a safe, easy and effective choice in prehospital management of pain. The impact of this feasibility trial, will hope to inform the larger multi-centred trial and then support the implementation of out-of-hospital Canadian National Guidelines for prehospital pain control, enabling paramedics to provide rapid, effective prehospital pain relief to patients.
Spinal anesthesia (SA) is a widely accepted anesthetic technique for hip fracture repair among elderly. Positioning for SA can be extremely painful. Effective management of pain is important for these patients comfort. Fascia Iliaca block (FIB) and Femoral nerve blocks are commonly used for analgesia in hip fracture patients. However, they often provide a modest reduction in pain. The Percapsular Nerve Group block (PENG Block) has the advantage that it covers the accessory obturator nerve. Aim of the study: compare FIB with PENG prior to positioning hip fracture patients for standardized SA. In a prospective randomized double blind we included 80 patients aged more than 65 years old, for whom pain was felt when raising the affected limb to 15 degrees. Patients were assigned to receive either ultrasound guided Fascia Iliaca block or Percapsular Nerve Group block using 20 mL Lidocaine 1.5% in both groups. We compared pain on positioning for spinal anesthesia using Verbal Rating Scale (VRS 0 = no pain , VRS 1 = mild pain, t 2= severe pain) for both groups. We also recorded different times to perfom block.
Medical and dental patients may experience fear commonly attributed to physical pain during the visit. By reducing pain perception, patient comfort and future patient compliance may be improved. Patient health may be improved by increasing compliance and promoting increased visits. This can lead to more frequent and timely preventative actions. The research purpose is to establish quantitative and qualitative data to support current, non-pharmacological methods for reducing pain sensitivity. More specifically, the investigators aim to determine if the use of auditory and visual (3D imaging) stimuli related to the regulation of breathing can decrease or modulate pain. Healthy participants between the ages of 18 and 60 will participate in a one week study, with two in lab appointments on day one and day seven. Participants will be split into two groups, one will undergo breathing awareness using auditory and visual technology (i.e. listen to one's own breathing with headphones and watch 3D image of lungs using virtual headset), and the second group will have breathing awareness without the use of technology (i.e. simply focusing on one's own breathing). At each appointment, the investigators will collect pain threshold data using thermal Quantitative Sensory Testing (tQST) and brain activity data using Functional near-infrared spectroscopy (fNIRS). tQST and fNIRS data will be collected before, during, and after each breathing awareness/control exercise. Quantifying change in pain intensity has been demonstrated by pain threshold comparison across a stimulus using thermal Quantitative Sensory Testing (tQST). Functional near-infrared spectroscopy (fNIRS) in coordination with pain stimulation has been shown effective at locating different hemodynamic cortical responses depending on pain perception and expectation. In the current study, functional resting states before and after pain stimulation will be quantitatively assessed using fNIRS. The study design will allow the investigators to determine if the use of auditory and visual (3D imaging) stimuli related to the regulation of breathing can decrease or modulate pain. Cortical responses will give additional insight into the areas related to the decreased pain threshold. The long term objective is to increase neurophysiological understanding that will improve patient care. If effective, the novel experimental methods used will help to standardize future pain evaluation techniques.
The experience of pain is more than the conscious perception of nociceptive signals. Emotional and motivational aspects accompany pain, leading to its aversiveness and motivation for avoidance. In chronic pain, a negative hedonic shift has been proposed that is characterized by disproportionally increased emotional-motivational compared to sensory-discriminative pain responses. Such a negative hedonic shift is, for example, mirrored in very high comorbidity rates of chronic pain and affective disorders such as depression and anxiety. The aim of this study is to develop methods that allow the differentiation of sensory-discriminative and emotional-motivational pain response and to characterize mechanisms of the negative hedonic shift.
The purpose of this study is to evaluate the analgesic effects of cannabidiol for patients who have undergone simple tooth extraction. Participants will be randomized to one of four arms: treatment-as-usual (TAU), cannabidiol 17mg/mL, cannabidiol 37mg/mL, or placebo.
There is Controversy about what is more critical volume or concentration to achieve an optimum analgesic treatment with quadratus lumborum block. From the experiences of the authors, the regular dose of 20 ml of Bupivacaine at 0.375% concentration could not be enough in some cases to produce an optimum analgesic treatment, especially in hip arthroplasties. What is proposed in this study is to evaluate whether the volume injected in the quadratus lumborum block is more important than the concentration of the local anesthetic in terms of control of pain during the next 24 hours after surgery and opioid consumption.
