Filter by:Preemptive analgesia is an intervention which provides an anesthetic prior to initiating a painful stimulus. This trial is examining the effects of a local anesthetic given at the point of innervation prior to performing a vaginal hysterectomy with suspension sutures.
The objective of this study is to assess the safety of the buprenorphine transdermal system (5, 10, and 20 mg) in comparison to placebo transdermal system in subjects with moderate to severe pain after orthopedic surgery. The double-blind treatment intervention duration is 72 hours during which time supplemental analgesic medication (intravenous morphine PCA) will be provided to all subjects in addition to study drug.
The perception of pain is a complex process that is not yet fully understood. With outpatient knee arthroscopy becoming standard of care, postoperative pain management has become increasingly important in caring for patients. Traumeel S is a homeopathic complex widely used in German-speaking Europe for orthopedic pain and inflammation. It contains a mixture of medicinal plants and minerals, all highly diluted. In some recent studies, Traumeel has shown anti-inflammatory and analgesic activity. In this study, the efficacy of Traumeel S will be compared with placebo in reducing pain during the first 48 hours after arthroscopy. Also compared will be 6 day pain levels, analgesic consumption, quality of life, post operative knee function, quadriceps atrophy and safety. The study design is double blind RCT. 98 patients, aged 18-40 and undergoing arthroscopic meniscectomy or chondroplasty will be enrolled in the trial. Patients will be randomized to receive either intraoperative join irrigation with Traumeel S and oral treatment with Traumeel S, or placebo irrigation and oral ingestion. Patients will continue to take active or placebo medication for 6 days. Pain will be recorded daily by the patient in the patient diary using an 11-point numerical rating score (NRS-11. Patients will also record daily consumption of primary and "rescue" analgesics. Range of motion (RoM) will be measured on days 6 and 30 post-operatively, and the Lysholm knee scale and circumference of thigh above patella will be measured at 30 days. All these measures will be compared with baseline. Patients will be contacted daily by the research assistant to encourage compliance and to record their daily NRS and analgesic consumption in the CRF.
Recent advances in the field of pain psychophysics that have enhanced the understanding of pain processing by the nervous system seem to characterize the individual pattern of pain processing, thereby enabling the prediction of a person's susceptibility to develop chronic pain consequent to surgery. In this project, the researchers propose to apply a wide array of advanced testing methods in order to prospectively assess the pain modulation pattern of pain free patients about to undergo an elective thoracotomy. Since about half of post-thoracotomy patients suffer from chronic neuropathic postoperative pain, the researchers expect to identify which tests predict a risk for this pain and the relative power of the relevant tests in this prediction, and to construct a short and applicable tool, the 'pain susceptibility profile', that will reliably predict the risk for the development of pain. The expected results of this project will serve the field of pain prevention by identifying patients at risk and tailoring interventions to reduce the risk of chronic pain.
The use of .5% Bupivacaine with epinephrine at the time of skin closure in cesarean deliveries will decrease post-op pain.
The study aims to compare standard techniques used to control pain after knee surgery. The investigators hypothesize that the fascia iliaca block is faster, safer and as good as or better than the femoral block, with or without a stimulating catheter.
Paracetamol is commonly used to reduce pain after operations. Recently anaesthetists have been using bigger doses of paracetamol because it has been suggested that bigger doses will work better. However these bigger doses have never been assessed scientifically in adult patients to see if they work better, and it has not been determined at which dose the maximum effect in reducing pain occurs. We We will investigate whether a 90 mg per kg body weight dose works better than a 60 mg per kilogram dose, in reducing pain after wisdom tooth extraction. We will also examine the pharmacokinetics (the way the body removes the drug) of paracetamol, and whether paracetamol changes the way blood clots at these doses. We will also examine whether these doses are safe, by monitoring liver enzymes, and making sure the blood level of paracetamol is not greater than that previously recognised to cause liver disease. The patients will be healthy volunteers scheduled to have wisdom tooth extraction. They will have blood taken at intervals for four hours after having the paracetamol. They will fill in pain scores at the same times they have blood taken.
The purpose of this study is to determine the effectiveness of aerosolized pain medication (.5% bupivicaine) delivered into the peritoneal cavity after laparoscopic gastric bypass surgery. This double blind study will include 50 patients. 25 will receive the aerosolized pain medication and 25 will receive a placebo (normal saline). All 50 patients will receive routine/typical methods of post-operative pain management. Post operative pain scores of the patients will be examined to determine the effect of aerosolization.
The study purpose is to compare the effectiveness of different methods for post-operative pain treatment after total knee replacement.
Ketorolac has been marketed for several years in other forms (tablet and injectable) for the short-term relief of pain. This study will test whether a new dosage form (nasal spray) containing ketorolac is effective at relieving the pain of major abdominal surgery, and will also assess product safety. Previous studies with the nasal spray have suggested that it is similar to the previously approved injectable form in effectiveness for pain relief and in its safety profile. Patients will be randomized in a 2:1 ratio to receive intranasal ketorolac or placebo when the pain reaches a moderate level (40 on a scale of 100) following surgery. After the first dose, subjects will receive study drug every 6 hours for 48 hours, and then as needed (up to 4 times a day) for a total of 5 days. If pain is not adequately relieved by the study drug, subjects will be given morphine sulfate or other standard analgesics. Follow-up safety evaluations will occur about 1 and 2 weeks after the start of dosing. Subjects will be asked to answer questions about their pain relief and any possible side effects of the drug during the study, and will be given physical examinations, including nasal evaluations, before and during the clinical trial. A small amount of blood will be drawn for routine clinical laboratory testing.
