Active clinical trials for "Pain, Postoperative"

This study will evaluate Panda, a smartphone-based pain assessment tool. During a child's recovery from surgery, a Post-Anesthetic Care Unit nurse will assess their pain, which helps determine what medication they need. Traditionally, this involves asking the child to rate their pain on a scale from 1 to 10, by moving a slider along a coloured scale or pointing to one of a series of faces on a piece of card. The Panda uses the same methods, but presents them on a smartphone screen. Our evaluation will ensure that the Panda gives the same pain scores as the traditional methods.

The purpose of this study is to compare post-cesarean section consumption of pain medication between two groups of patients undergoing scheduled cesarean section at term gestation who receive a single-dose of intraoperative steroid (dexamethasone 8 milligrams) versus placebo at 24 hours after surgery. The hypothesis is that a single perioperative dose of dexamethasone 8 mg will significantly reduce postoperative opioid consumption at 24 h in women having cesarean delivery under spinal anesthesia.

In preparation for future large-scale genome wide association studies, reliable methods must be developed for measuring perceived pain and for estimating the effects of potentially confounding factors such as appropriate covariates. The major objectives of our pilot investigation are to develop optimal methods to characterize the primary endpoint of the study-knee pain, and to gather preliminary data on genetic markers in the human genome that are associated with a certain pain phenotype. The specific issues for this study will be to carry out a preliminary gene association analysis of acute perioperative pain in individuals undergoing total knee replacement and to define a pain phenotype that is composed of multidimensional domains such as opioid consumption, inflammatory markers, anxiety level, degree of catastrophizing, etc. This pain phenotype has to be sensitive enough to pick up changes in pain experience that can be attributed to single nucleotide polymorphisms.

This double-blind, randomized, controlled clinical trial comparing patient-reported pain and pain medication/narcotic use between patients randomized to treatment (bupivacaine) or placebo (saline) delivered via pain pump to the mastectomy site. Candidates will have chosen to have a mastectomy on one side immediately followed with tissue expander placement breast reconstruction. Patients will be randomized 1:1 to bupivacaine- (treatment) or saline-(placebo) filled percutaneously-placed pain pumps; neither the participants nor the study staff will know participants' treatment. Data on patient-perceived pain and pain medication use will be collected before surgery, during surgery, and after surgery on Days 1, 2, 3, 7, and 90, and at Years 2 and 4 by phone. The investigators hypothesize that patients randomized to the treatment (bupivacaine) group will have significantly lower pain scores and use less pain medicine than patients who receive placebo during the first 90 days following their surgery. The Year 2 and Year 4 follow-ups are included as tertiary endpoints to capture differences in chronic pain, and patients will be asked to complete the same questionnaires as at the Day 90 follow up.

The study is a prospective, randomized, open-label comparison of a multimodal regimen and a standard, narcotic-based regimen for postoperative pain control in patients undergoing surgery for an operatively indicated, isolated extremity fracture. The investigators will be measuring pain levels, narcotic use, patient satisfaction, patient reported function, adverse events and fracture union. The investigators hypothesize that this multimodal regimen will lead to improved pain, less narcotic use and improved satisfaction as compared to the standard regimen.

What is the influence of methadone on postoperative analgesia after lumbar interbody fusion in opioid naïve patients or patients who are taking less than equivalent of 15 mg IV morphine each day? What is the incidence of opioid related postoperative side effects after the administration of methadone in the operating room?

The purpose of this study is to generate further insight into the role and effectiveness of the amide local anesthetic lidocaine as an adjuvant postoperative analgesic after adult spine surgery. The effect of perioperative intravenous lidocaine infusion on postoperative rehabilitation and the inflammatory response will also be examined.

This study will test the null hypothesis that low-dose ketamine given peri-operatively will have no effect on the development of chronic post-surgical pain, in patients undergoing thoracotomy or video assisted thoracic surgery (VATS) procedures A double-blind, randomised placebo-controlled trial will be used to test the null hypothesis. Potential participants due to undergo either thoracotomy or video assisted thoracic surgery (VATS) will be identified by the collaborating thoracic surgeons in the out-patient department. Patients will be sent information about the study by post, prior to admission for surgery. If they are willing to participate, written consent will be sought on the ward preoperatively, where they will complete baseline measures of pain. Patients will be randomised to receive an intravenous infusion of placebo (saline) or ketamine running at 0.1mg/kg/hour, starting 10 minutes prior to the surgical incision and continuing for the first three postoperative days (96 hours in total). Prior to starting the infusion a loading dose of ketamine (0.1 mg per kg) will be administered.

Postoperative pain, nausea and vomiting (PONV) are the most common complications after anesthesia and surgery. Women undergoing mastectomy with axillary dissection are at a particularly high risk for the development of PONV and an incidence of 60-80% in patients receiving no antiemetic has been reported. Emetic episodes predispose to aspiration of gastric contents, wound dehiscence, psychological distress, and delayed recovery and discharge times. These justify the use of prophylactic antiemetics in women scheduled for mastectomy. Most of the currently used antiemetics, including antihistamines, butyrophenones and dopamine receptor antagonists have been reported to cause occasional undesirable adverse effects, such as excessive sedation, hypotension, dry mouth, dysphoria, hallucinations and extrapyramidal signs. Antiserotonins (e.g., ondansetron) are available for the prevention and treatment of PONV in patients undergoing various types of surgery [4]. However, the use of prophylactic antiemetic therapy with antiserotonins has been criticized for being too expensive. Dexamethasone was first reported to be an effective antiemetic regimen in patients receiving cancer chemotherapy. The purpose of this study was to evaluate the efficacy of dexamethasone treatment for reducing pain and PONV as well as analgesic and antiemetic requirements in women undergoing general anesthesia for mastectomy with axillary lymph node dissection.

The purpose of this study is to characterize the safety, pharmacokinetics (PK), and efficacy of intravenous (IV) buprenorphine in pediatric patients.
