Active clinical trials for "Pain, Postoperative"

Pain management after gynecological surgeries is essential for early mobilization of the patient, decrease postoperative complication and hospital stay. The use of opioids is associated with adverse effects such as nausea, vomiting, ileus, pruritus, sedation and respiratory depression. Previous studies stated that pregabalin has been used to reduce pre-operative anxiety, acute postoperative pain, postoperative opioid requirements, postoperative nausea, vomiting and postoperative delirium. The most effective dose of pregabalin to relief postoperative pain with least side effect is still under trial. In this study we will compare between two different doses of pregabalin when given as oral premedication in patients undergoing gynecological surgeries under spinal anesthesia regarding postoperative pain in order to reduce opioids consumption and subsequently avoid opioid-related adverse effects.

Split-thickness skin grafting is the current standard of care for the reconstructive procedures in managing burn injuries and traumatic tissue defects. Harvesting split-thickness skin creates a new partial thickness wound that is referred to as the donor site . Donor site pain is one of the most distressing symptoms reported by patients in the early postoperative period. Larger donor sites stimulate a greater number of pain receptors and consequently pain is proportional to the size of the graft harvested.Often, the donor site is reported to be more painful than the recipient site,affecting early mobilization, sleep, and need for analgesics postoperatively.

Effective postoperative pain management in elective hip surgery is crucial for the patients well-being, rapid mobilisation and potential reduction of length of stay. In addition to standard intravenous pain medication, anaesthetic blocks are reportedly effective. Recently, the PENG block, a pericapsular pain block without impairment of the motor function has been introduced in literature and performed at the investigator's hospital (HFR Fribourg, Switzerland) for total hip arthroplasty and surgical hip dislocation - the two most commonly performed elective hip surgeries. As high-quality evidence on the effectiveness of this novel block is lacking, the investigator's objective is to evaluate the effectiveness of (1) patient-reported pain reduction, (2) total consumption of postoperative morphine, and the length of stay at the hospital.

This trial intends to evaluate Remimazolam Besylate's availability and safety compared with propofol.

The investigators are looking to recruit patients into a study demonstrating the effectiveness of a superficial nerve block involving the thoracolumbar interfascial plane (TLIP) in reducing postoperative pain in those undergoing spinal surgery

A multicenter, randomized, open-label, active controlled pragmatic clinical trial that evaluates the safety and efficacy of S (+) -ketamine for postoperative acute pain in adults in perioperative settings.

The aim of this project is to evaluate the efficacy of preoperative erector spinae blocks in arthroscopic hip surgery. This will be a prospective randomized controlled trial.

Study Background Osteoarthritis of the knee is a common degenerative musculoskeletal condition which affects nearly five million people in the United Kingdom. Some patients will require total knee replacement surgery if their symptoms of pain and disability are not controlled adequately by so-called 'conservative' measures such as weight-loss, activity modification and analgesic (pain-killer) medication. Over the past ten years our understanding of pain-relief strategies during total knee replacement, often termed 'Enhanced Recovery' principles, has helped improve patient care and reduced length of hospital admission. 'Enhanced Recovery' principles recommend the use of analgesic medications which can be delivered in a variety of ways e.g. tablets and injections. This is termed 'multi-modal' analgesia. Prior to total knee replacement, the patient will receive an injection around the nerves in the spine (regional anaesthesia) which numbs the patient from the waist down and allows the surgeon to perform the operation in a safe and pain-free manner. During the operation, surgeons often choose to deliver extra local anaesthetic to prolong the degree of pain-relief in the immediate post-operative period. This can enable patients to mobilise early and is associated with greater long-term satisfaction. There are two main methods of delivering this extra form of pain-relief during the operation. Peri-articular injection involves multiple injections of local anaesthetic into the soft-tissues surround the knee. In contrast, Intra-articular injection involves a single injection directly into the knee joint once the operation is finished. Currently, there is no clear evidence available to Orthopaedic surgeons to inform us which technique is better at providing pain relief for patients undergoing total knee replacement surgery. All patients undergoing total knee replacement surgery for osteoarthritis of the knee will be invited to participate in this study. We intend to recruit a total of 120 patients. During the patient's total knee replacement surgery, they shall receive an injection of local anaesthetic around the soft-tissues of the knee (Peri-Articular Injection) or directly into the knee joint itself (Intra-Articular Injection). The decision regarding which treatment they receive is decided entirely by randomisation. Following the operation, a member of the research team will assess the patient on the ward to collect information regarding levels of pain and overall satisfaction. The type of injection received shall be kept secret from both the patient and the member of the research team collecting the post-operative pain scores. After the patient has been safely discharged from hospital, we intend to follow-up all participants for one year. This will involve routine clinic appointments at six weeks and twelve months following surgery. This will involve review and clinical examination by a member of the orthopaedic team who have treated the patient whilst in hospital and/or a member of the research team. In addition, all patients will be asked to complete a questionnaire at twelve months regarding their level of function and pain. These questionnaires have been used widely in the medical literature and have a strong evidence base for their use. What is the aim of this study? The aim of this study is compare the amount of pain relief provided by two different methods of local anaesthetic injection techniques used in total knee replacement surgery. In addition, we would like to know if this influences the patient's immediate and long-term recovery after surgery.

Minimal invasive thoracoscopic surgery has been used widely for common thoracic diseases in recent years. Patients who received thoracoscopic surgery recovered much quickly and returned to their daily life sooner because of small operation wound and less invasion. However, operative pain was still an important factor, which might contribute to several post-operative complications. In daily practice, patients received oral/intravenous form non-steroidal anti-inflammatory drugs and opioid agents, or patient-controlled analgesia for post operative pain control. However, some side effects were observed occasionally. The role of acupuncture in post-operative pain control was frequently discussed in recent research. The main mechanisms of acupuncture in pain control were (1) to stimulate the release of endogenous opioid and (2) to block TRPV1 receptor. The randomized controlled trial arranged by Gary Deng and his colleagues in 2008, was the first clinical trial investigated the role of acupuncture in post-operative pain control for traditional thoracotomy patients. However, there was no further research about the role of acupuncture applied to minimal invasive thoracoscopic surgery. Thus, the aim of this randomized controlled trial was to investigate the role of acupuncture in post-operative pain control for minimal invasive thoracoscopic surgery patients. In order to deliver a safe and effective way in pain control, and to save medical cost and promote quality of patient care.

All patients over the age of 16 undergoing primary or revision anterior cruciate ligament reconstruction with the use of bone-patellar-bone autograft are eligible for the study. Patients will be randomized pre-operatively to receive either an adductor canal nerve block (single injection) or a femoral nerve block (single injection). Post-operatively, the primary outcome measures of pain level using visual analog scale as well as narcotic and non-narcotic analgesic requirements will be measured.
