Filter by:Osteoarthritis of the knee joint is common and total knee arthroplasty (TKA) is performed in patients with advanced joint degeneration, no response to conservative treatments, severe pain and joint instability. Severe pain levels between 4 and 8 in visual analog pain scale (VAS) scores have been reported in the postoperative period. Multimodal analgesia is considered to be the best option for pain control after total knee arthroplasty. Multimodal analgesia is defined as the combined use of different analgesia techniques such as neuraxial analgesia, peripheral nerve blocks, patient-controlled analgesia and different analgesic drugs. For this purpose, peripheral nerve blocks are effectively applied as a component of multimodal analgesia. Thus, side effects such as nausea, vomiting, pruritus and sedation that may occur due to opioid use are reduced. At the same time, in addition to providing effective analgesia, peripheral blocks contribute to early initiation of rehabilitation of the knee joint, early ambulation, reduction of pulmonary complications and early discharge from the hospital. Recently, objective methods such as skin vasomotor reflex analysis, pupilometry, pulse plethysmographic signals and analgesia nociceptive index (ANI) have been used to standardize the need for intraoperative analgesia in patients under general anesthesia. Among these methods, ANI is a non-invasive method that provides continuous measurement of parasympathetic tone, which is a part of the autonomic nervous system. Electrodes are placed on the chest wall on both sides of the heart and the patient is monitored. The investigators aimed to compare the analgesia nociception index (ANI) and the conventional method to determine perioperative analgesic needs in patients undergoing total knee arthroplasty under general anesthesia with femoral nerve block.
This is a randomized controlled parallel clinical, prospective split mouth, triple blinded study. Sample size calculation was conducted and it was 25 subjects per group for a total of 50 sides to compensate for drop-outs. Patient selection and preparation: All root canal treatments were performed by a single endodontic consultant. All subjects were selected from walk in patients presented to the endodontic clinic of the British university in Egypt. Cases that met the inclusion criteria where selected for this study. All patients were verbally informed about the procedure's benefits and that the results of the treatment will be used to this study and the risks of the procedure was explicitly explained to them. After the verbal consent patients were handed a written form consent to sign upon. All data of post-operative pain were recorded by a second blinded clinician through a visual analog scale (VAS). Post-operative monitoring periods will be recorded in 12 hours, 24 hours, 3 days and one week Data was sent to the statistician with group names only to fulfill the triple blinding criteria and results will be interpreted
Pain is a subjective feeling,and pain experts have been trying to assess it using objective methods. Pain index (PI) is extracted from electroencephalographic as an objective diagnostic tool for chronic pain. This study is a diagnostic test aims to explore the reliability and validity of PI, with numerical rating scale(NRS) as the gold standard.
The aims of this validation study are the testing of the Bernese Pain Scale for Neonates' (BPSN) psychometric properties. The variability of pain reactions related to behavioral and physiological patterns across time will also be examined. Furthermore, the influence of contextual factors on the variability of pain reactions across gestational age groups will be explored. The results will be used for modifications of the BPSN to account for contextual factors in future clinical pain assessment in neonates.
The purpose of this study is to evaluate the effectiveness (level of pain control) and safety of the administration of 3 different dose levels of CG5503 compared with oxycodone and with placebo in patients who have had a bunionectomy, and to assess the safety of the drug for 9 days after patients are discharged from the hospital.
The purpose of this study is to evaluate in patients who are eligible for elective primary total or partial joint replacement of the hip or knee due to chronic osteoarthritis the efficacy (level of pain control) of CG5503 over 5 and 10 days compared with placebo, and to assess the safety and tolerability of multiple doses of CG5503 IR patients.
