Active clinical trials for "Pain, Postoperative"

This study will examine whether pre-incision infiltration of the skin cut site can attenuate post operative pain after a cesarean section. One hundred and twenty women will be allocated to get 20 ml of either placebo or 1% xylocaine at the site of skin incision. We will also examine possible effect of this infiltration of parameters of wound heeling and scar formation, six weeks post partum.

Randomized trial comparing lumbar plexus catheter versus femoral nerve catheter (single-shot femoral block as control group) for postoperative pain control after anterior cruciate ligament repair in children (age 11-21). Primary outcome is pain scores for the first 72 hours. Secondary outcomes include opioid consumption, incidence of opioid side effects and quality of recovery (previously validated scale). Our hypothesis is that lumbar plexus catheter will provide superior pain control and overall quality of recovery compared to femoral nerve catheters.

This double blinded, placebo controlled, study seeks to determine the efficacy of preoperative anti-inflammatory therapy on the reduction of postoperative pain in knee arthroplasty surgery. Pre-emptive use of NSAIDS has demonstrated only modest reduction in post-operative pain in previous studies. However, the short duration of dosing in those studies did not capitalized on the anti-inflammatory properties of NSAIDS. Short-term use of NSAIDS only provides pain relief and does not address inflammation. Traditional NSAIDS cannot be used preoperatively due to platelet effects. Celecoxib, however, is both an analgesic and anti-inflammatory, but does not interfere with bleeding. It can therefore be safely used before surgery. This study hypothesizes that the use of celecoxib for seven days preoperatively reduces postoperative inflammation and consequently pain. A detailed Medline search has not identified any studies into the preoperative use of an NSAID at a dosing level that achieves anti-inflammatory effects.If effective in reducing postoperative pain, this research could lead to a new understanding of the role inflammation plays in orthopedic procedures and other elective procedures and thus improve patient outcomes in the future.

Nalbuphine is opioid mu receptor antagonist and kappa receptor agonist This study was designed to investigate the interaction between nalbuphine and morphine

Pain is common in the first 2 days after major craniotomy. Inadequate analgesia may lead to an increased risk of postoperative complications. Most pain following craniotomy arises from the pericranial muscles and soft tissues of the scalp. Scalp nerve blocks with local anesthesia seem to provide effective, safe, however transient postoperative analgesia which does not seem to meet the requirements of craniotomy. Currently, peripheral dexamethasone has been observed to significantly prolong the duration of analgesia of nerve blocks (e.g., saphenous nerve block, adductor canal block, thoracic paravertebral block, brachial plexus nerve block). On the contrary, a study reported that perineural dexamethasone did not appear to prolong the analgesic time after supratentorial craniotomy. However, all patients in this study were given 24 mg of oral or intravenous dexamethasone regularly at least 7 days during the perioperative period, which possibly masked the role of single local low doses of perineural dexamethasone. Therefore, the analgesic effect of single dexamethasone for scalp nerve blocks without the backdrop of perioperative glucocorticoid deserves further clarification.

The study is being conducted to evaluate the efficacy, safety of HR021618 and to explore the reasonable dosage of HR021618 for Pain Management after Orthopaedic surgery.

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.

Ultrasound-guided brachial plexus blocks are used successfully for upper extremity surgeries. In this randomized prospective single-blind study, ASA I-II patients aged 18-65 years undergoing hand, wrist, and forearm surgery will be randomly divided into two groups. First group will receive ultrasound-guided coronal oblique supraclavicular block using a 22G, 50 mm stimulator needle, and the second group, ultrasound-guided lateral sagittal infraclavicular block using a 22G 100 mm stimulator needle. We will prepare, 30 ml of 1:1 0.5% bupivacaine and 2% prilocaine with 5 mcg adrenaline per milliliter as local anesthetic mixture. Block application time, block success, sensory and motor block levels, and postoperative analgesia time will be recorded and compared between the groups. Accordingly, the success rate of the two methods will be evaluated.

The aim of this study is to determine the minimal effective ropivacaine concentration required to provide adequate analgesic femoral nerve block in 90% of patients (MEAC90)

This study investigates the effectiveness of the erector spinae plane block (ESPB) in pain management of patients undergoing PNL.
