Active clinical trials for "Pain, Postoperative"

The role of a single dose of intraoperative clonidine on postoperative opioid requirements, pain intensity and opioid-related side effects in patients undergoing surgical treatment for endometriosis remains scarcely explored. A prospective double-blind, randomised controlled trial investigating the effect of a single-dose of intraoperative clonidine in patients undergoing surgical treatment for endometriosis is therefore conducted.

The goal of this clinical trial is to evaluate Fu's Subcutaneous Needling (FSN) in postoperative pain in patients with Lumbar Spine Surgery (LSS). The main questions it aims to answer are: Is FSN effective for postoperative pain? Dose FSN decrease the tissue hardness after LSS? Dose FSN have the effect of anti-inflammatory after LSS? Participants will receive routine analgesic and FSN after LSS. Researchers will compare Sham group to see if FSN being effective for postoperative pain.

The patients will be randomly assigned to standard therapy or standard therapy+ESP nerve block. After surgery pain level and narcotic consumption will be measured, and vital signs and side effects will bo monitored for up to 72 hours. 6 months after surgery a phone interview will be conducted to asses chronic pain

Chronic knee pain remains a disabling disease despite current treatment strategies. There is an increase in the prevalence of osteoarthritis (OA) of the knee in the general population, presently affecting approximately 450,000 individuals in Belgium. A total knee replacement is a viable alternative for severe knee OA that does not respond to conservative therapy. Unfortunately, up to 53% of patients who undergo a total knee replacement develop persistent post-surgical pain (PPSP). There is currently no effective therapy for PPSP. A radiofrequency (RF) treatment applies high frequency current on the nerve responsible for pain conduction, resulting in an interruption of the transmission of pain. This can be applied to the nerves innervating the knee joint - the superolateral, superomedial and inferomedial genicular nerves - and could be an alternative, minimally invasive treatment for patients with knee OA who fail conservative treatments and for patients with PPSP. Data from the recent literature indicates that this treatment leads to a reduction of pain intensity and could result in an improvement of knee function, of the psychological state of the individual, and finally in an increase in health-related quality of life. Furthermore, RF of the genicular nerves could help avoid or delay a total knee replacement therefore potentially contributing to cost reduction. Both cooled and conventional RF treatments are reported in the literature to improve pain. The use of water to cool the RF electrodes results in an increased lesion size by removing heat from adjacent tissue, allowing power delivery to be increased. As a consequence, cooled RF could result in a higher chance of success and longer duration of effect. Until now, the studies performed on cooled RF are industry initiated and a direct comparison between conventional, cooled and a sham procedure is lacking. The aim of the COGENIUS trial is to investigate the effect of the two types of RF treatment on individuals experiencing chronic knee pain that is resistant to conservative treatments. For this purpose, the efficacy and cost-effectiveness of cooled and conventional RF will be compared to a sham procedure in patients suffering from knee OA and PPSP after total knee replacement.

This study aims to evaluate the effect of local administration of bupivacain in the cesarean section incision for postoperative pain control, using the visual analogue pain scale (VAS) and assessing the need for rescue analgesia after surgery.

A randomized controlled trial evaluating the efficacy and safety of single-shot intraoperative methadone for postoperative pain in patients undergoing tonsillectomy. Fentanyl is used as an active comparator

Spinal surgery is often burdened by perioperative pain and its treatment presently represents a challenge for anesthetists. An inadequate intra and postoperative analgesic therapy leads to a delay in the mobilization of the patients, prolonged hospital stay and thromboembolic complications, as well as the onset of chronic pain syndromes . Effective pain treatment can help improve surgical outcome for patients undergoing spinal surgery. From the pathophysiological point of view pain in vertebral surgery can originate from different anatomical structures: vertebrae, discs, ligaments, dura mater, facet joints, muscles and skin-subcutis. The terminal innervation of these tissues originate from the dorsal branches of the spinal nerves, and this represents a target a multimodal approach to perioperative analgesia in vertebral surgery. Systemically administered drugs such as NSAIDs, opioids, ketamine, intravenous lidocaine could benefit from the addition of locoregional therapies such as neuraxial blocks (anesthesia peridural or subarachnoid) or as shown more recently by other anesthesia techniques locoregional ultrasound-guided In recent years the anesthesiological interest has focused on the Erector Spinae Plane Block (ESPB). First described by Forero et al, it is a paraspinal interfascial block targeting the dorsal and ventral branches of the spinal nerves just after their emergence from the spinal cord. In the ultrasound-guided technique the local anesthetic is injected between the deep fascia of the muscle itself and the transverse processes of the vertebrae at the level interested. The aim of this study is to evaluate the efficacy of ESPB when compared to wound infiltration in patients undergoing laminectomy

This clinical study is a randomized, double-blind, double-dummy, parallel group, multi-center, active and placebo-controlled trial evaluating the analgesic efficacy and safety of NTM-001 in subjects with moderately severe postoperative pain after bunionectomy surgery. This study is designed to compare the efficacy of NTM-001 to placebo. Intravenous (IV) morphine serves as an active comparator to determine assay sensitivity and support assessment of opioid-level analgesia for NTM-001. Effectiveness, safety, and tolerability parameters will be descriptively compared between treatment arms.

Applying nanotechnology in drug delivery systems improved the bioavailability and kinetic profile of drugs in biological systems

The purpose is to find out if incorporation of an intraoperative electro auricular acupuncture protocol when added to a standard multimodal analgesic regimen for patients undergoing surgery to repair lower leg fracture under spinal anesthesia will help reduce postoperative opioid use.
