Active clinical trials for "Pain, Postoperative"

The study will evaluate the effect of Dexmedetomidine sedation on the duration of infraclavicular block in patients scheduled for surgery of elbow, forearm and/or hand. All patients will receive infraclavicular block before the surgery and then they will be randomized to receive either Dexmedetomidine or Propofol sedation. Duration of the sensory block will be evaluated in recovery room, 24 and 48 hours after the surgery. Hypothesis: Primary: Dexmedetomidine sedation increases the duration of sensory infraclavicular block in patients scheduled for upper limb surgery. Secondary: Dexmedetomidine sedation Gives an adequate level of sedation during the surgical procedure Reduces the requirements of postoperative opioids Improves the quality of sleep on the night of the surgery Increases patients satisfaction regarding the anesthesia technique Dexmedetomidine sedation is safe and easy to use Dexmedetomidine sedation provides less respiratory depression during the procedure.

The objectives of this proof of concept study are to evaluate the safety and preventive analgesic efficacy of a single preoperative intrathecal administration of AYX1 Injection in patients undergoing unilateral total knee arthroplasty.

Pelvic organ prolapse is an herniation process, needing a mesh reconstruction for long lasting therapeutic effect. Yet, mesh implants were reported to be related to severe adverse effects. This study looks at the potential benefit of mesh size reduction regarding avoiding operative complications.

The purpose of the study is to examine the safety and efficacy of liposome bupivacaine for intercostal nerve block in subjects undergoing posterolateral thoracotomy.

A Prospective double-blinded randomized clinical trial to test the effect of transversus abdominis plane block on postoperative pain and opoid consumption after abdominal hysterectomy. Two groups of each 24 patients. All patients are given general anesthesia. The patients are randomized to have a ultrasound guided bilateral transversus abdominis plane block with either 2 x 20 ml 0,75 % ropivacaine or 2 x 20 ml of 0,9 saline. All patients are provided with a PCA for self administration of morphine. Pain score on visual analog scale, nausea and vomiting are monitored at 1, 2, 4, 6, 8 and 24 hours postoperatively as well as the total consumption of morphine after 24 hours.

The purpose of this study is to compare the efficacy and safety of extended release (ER) tramadol hydrochloride (HCl)/acetaminophen with immediate release (IR) tramadol HCl/acetaminophen in participants with moderate to severe (very serious, life threatening) postoperative pain.

The main objective of the trial is to complete a double-blinded randomized controlled trial of a lumbar plexus block with the Shamrock technique versus the Lumbar Ultrasound Trident technique by estimating the time of performance of lumbar plexus blocks in healthy volunteers. Secondary objectives include a) estimates of number and depth of needle injections, distance of injection site from the midline, minimal electric nerve stimulation to trigger muscular response and the type of response, and volunteer discomfort during block injection, b) measurements of plasma lidocaine and mean arterial blood pressure, c) examinations of sensory block of the dermatomes T8-S3 and motor block of the femoral nerve, the obturator nerve, the hip abductor muscles, and the hamstring muscles, d) success rate of lumbar plexus block, e) perineural and epidural distribution of local anesthetics added contrast visualized on magnetic resonance imaging (MRI) scanning, and f) cost-effectiveness for the Shamrock technique versus the Lumbar Ultrasound Trident Technique for lumbar plexus block in healthy volunteers. The hypothesis is that the Shamrock technique is faster to perform than the Lumbar Ultrasound technique, and that the success rate of the Shamrock technique is equal to or higher than the Lumbar Ultrasound Trident technique.

The 3-midline-ports technique is a safety approach and associates lower postoperative pain, when compared with the standard "French" technique.

The aim of this study is to compare the efficacy of the analgesic effect of the preoperative femoral nerve block alone versus combined femoral, sciatic, obturator and lateral femoral cutaneous nerve blocks in patients after TKA in the immediate postoperative period.

The purpose of this study is to determine if the addition of a sciatic nerve block (SNB) to a continuous femoral nerve block (CFNB) improves post-operative analgesia after knee arthroplasty.
