Filter by:To observationally compare the analgesic efficacy of LIA and S-FICB techniques and to record the pain scores of patients who underwent bilateral knee operations in the postoperative period.
This prospective randomized interventional study aims to compare the effects of two peripheral nerve blocks, the periencapsular nerve block (PENG) and iliopsoas block (IPB), on analgesia and motor function after hip surgery. The main questions it aims to answer are the effectivity of postoperative pain management the preservation of motor movement. Participants will receive standardized general anesthesia and postoperative PENG or IPB in either Group. Researchers will compare the total amount of rescue analgesia and numeric rating scale with accompanying evaluating motor function at the same time intervals within 24 hour.
Femur Fractures (PF) are nowadays one of the main social and health problems in industrialized countries. PF are defined as crack or break of the proximal femur and they represent an important cause of morbidity and mortality in elderly population. The main prospective and retrospective studies do not show the superiority of subarachnoid anesthesia over general anesthesia in terms of 30-day mortality and post-operative complications, however they always recommend the execution of PeripheralNerve Blocks (PNB). Loco-regional anesthesia plays a fundamental role in the treatment of peri-operative pain assuring better hemodynamic stability and has already fully entered national and international pain management protocols, because it allows faster recovery times with a reduction in the use of intravenous analgesic drugs in particular opioids and consequently a faster discharge and a reduction in peri-operative complications and the costs of assistance. The aim of our study will be to propose an anesthetic approach based on PNB that could be particularly suitable for frail patients especially when Neuroaxial Anesthesia (NA) is not feasible due to difficulty to position the patient or to the withdrawal time of anticoagulant or antiplatelet therapies.
This study is evaluating music vs midazolam as a means of anxiolysis for preoperative single-shot nerve block placement.
Although the superiority of ultrasound guidance over neurostimulation (NS) has been demonstrated, it has its limits, namely when used for a deeper block (device limits) or if used by a less experienced operator (ability to recognize structures, to correctly position the needle). In addition, its use has failed to consistently prevent intra-neural injection. The question of the usefulness of NS in addition to ultrasound is therefore still relevant. A great geographical disparity exists in the habits of nerve localization. The reluctance to use NS stems mainly from doubts about its effectiveness. The threshold used to consider that the needle is sufficiently close to the nerve and the one used to exclude an intraneural injection have been disputed in several studies. Another weakness of studies concerning NS since the advent of ultrasound guidance is the impossibility of generalizing the results. All clinical studies were performed in an academic setting, and a large majority of them specify that the blocks were performed by - or supervised by - regional anesthesia experts. The only study that attempted to determine the sensitivity of NS used ultrasound as a gold standard. The choice of the ultrasound position as the gold standard is debatable, since it is dependent of the operator. The clinical success of nerve blocks would be a better standard. No study to date has made it possible to calculate the specificity and sensitivity of NS in addition to ultrasound guidance, and therefore, to obtain the positive and negative predictive values of the technique. Obtaining these values could allow each clinical setting or individual to determine the contribution of NS to their rate of success, as a modest increase in the success rate or a minimal decrease in the risk of neuropathy would be clinically significant. The hypothesis is that the sensitivity and specificity of NS justifies its use in combination with ultrasound guidance in most settings, but that the gain in efficiency varies depending on the context (for example depending on the local success rate). To determine the required sample size to test this hypothesis and plan for a definitive study on the question, the investigators need to know what is the local failure rate (incidence of studied event) and what could be the possible rate of patient enrollment. This preliminary, feasibility study will aim to confirm that the local failure rate is compatible with the 5% rate observed in the literature.
The purpose of this study is to evaluate whether liposomal bupivacaine is superior to normal bupivacaine in terms of providing better pain control postoperatively after total knee arthroplasty.
In the orthopedic foot and ankle surgeries, the effects of postoperative popliteal nerve block applied for palliation of pain and local anesthetic agent in two different concentrations (0.166 and 0.250) which were used in popliteal nerve block procedure, will be investigated.
Video-Assisted Thoracoscopic Surgery (VATS) is a minimally invasive surgery that utilizes camera based scopes and specialized instruments through keyhole sized ports to remove lesions in the thoracic cavity. Despite reduced surgical trauma compared to the traditional thoracotomy approach, patients continued to experience moderate to severe postoperative pain. Pain medication such as opioids is commonly utilized for postoperative pain control but is associated with side effects. The use of nerve blocks, such as the recently described erector spinae plane block (ESPB) has been shown in case reports to reduce pain and thus has the potential to improve patient recovery and decrease the risk of pulmonary complication. This study aims to investigate the analgesic effect of ESPB in managing pain following VATS.
This is a prospective, randomized, double blind study of adding dexmedetomidine to ropivacaine for Brachial plexus block and assessing the analgesia with VAS pain scales(0-10), Satisfaction scale by VAS scale(0-10) and time to first analgesic consumption. This study mainly aims to investigate whether addition of dexmedetomidine helps in increasing the duration of analgesia.
Background: Local anesthetic (LA) concentration and nerve block duration is sparsely described in a heterogenic study mass. Aim: To investigate the effect of LA concentration on peripheral nerve block duration in healthy volunteers. Methods: Randomization of 60 healthy volunteers who will receive 1 of 5 different volumes of LA (ropivacaine) using a constant dose. Primary endpoint: Sensory nerve block defined by insensitivity towards cold.
