Active clinical trials for "Pain, Postoperative"

Hysterectomy (removal of the uterus) is the most common major gynecologic surgery performed in Canada. With a focus on minimally invasive techniques and optimization of peri-operative pain control, gynaecologists have made great strides towards reducing hospital stay and accelerating post-operative recovery. These are essential achievements, both for patients and their families and for our resource-limited public healthcare system. Optimization of peri-operative pain control is multifactorial and includes, for example, administration of pre-operative analgesics, infiltration of incision sites with local anesthetic and provision of post-operative pain medications. As the understanding of pain mechanisms evolves, the incorporation of intra-operative nerve blocks has become yet another effective strategy to reduce post-operative pain. The presacral nerve plexus, which carries nerve fibers from the uterus to the brain, is an important pathway that transmits midline pelvic pain in women. Destruction of the pre-sacral nerves has been shown to provide excellent pain control in a variety of clinical settings. While transection of the presacral nerve at the time of surgery is technically challenging, instilling a presacral nerve block is surprisingly straightforward making this technique safe to perform in the hands of many gynecologists. In this technique, local anesthetic is instilled into the presacral space using a needle inserted through the abdomen. Given that the presacral nerve plexus is an integral pain pathway for the uterus, the investigators hypothesize that the addition of a presacral nerve block during laparoscopic (camera surgery) hysterectomy would confer an additional reduction in immediate post-operative pain. The proposed study therefore aims to look at the impact of presacral nerve block versus a sham (blank) block on immediate post-operative pain in a group of women scheduled to undergo laparoscopic hysterectomy.

This study will compare continuous intravenous lidocaine against single-injection transversus abdominis plane (TAP) block as a modality for postoperative analgesia in kidney transplant surgery.

To study and evaluate the Effectiveness of Treatment by Percutaneous Electrical NeuroStimulation (PENS) for post-operative pain in Cesarean Section patients using First Relief

This clinical study is designed to assesses the benefit of adding pulsed shortwave therapy to the postoperative pain and recovery protocol following Cesarean section. Pulsed shortwave therapy is a safe adjunct pain therapy for acute and chronic pain.

Women undergoing elective cesarian section will be assigned to 3 groups for postoperative analgesia: Scheduled doses of IV acetaminophen + PO Ibuprofen Scheduled doses of PO acetaminophen + PO Ibuprofen "On demand" doses of acetaminophen, dipyrone and ibuprofen.

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)

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 purpose of this study was to evaluate the Efficacy and safety of HR18042 tablets for the Treatment of Post-surgical Pain After extraction of impacted tooth, find the optimal dose.

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.
