Active clinical trials for "Pain, Postoperative"

Erector Spinae Plane Block is a newly defined regional anesthesia technique. Its use for many indications has been identified by case reports in the literature. As the investigators have considered that erector spinae plane block could be efficacious for providing postoperative analgesia in laparoscopic cholecystectomy, the investigators have implemented the application of this blockade into practice at the clinic.Oblique subcostal transverse abdominis plane block (OSTAP) is another regional anesthesia technic used for postoperative analgesia in laparoscopic cholecystectomy. Main purpose of this study is to compare the analgesic effect of ultrasound-guided erector spinae block and OSTAP in laparoscopic cholecystectomy.

Multimodal analgesia is used to control postoperative pain in hip surgery. Quadratus lumborum block is an effective regional anesthesia technique for hip and proximal femur surgery. The erector spinae plane block applied to the lumbar region was also reported to provide effective analgesia in these surgeons. In this study, we aimed to determine and compare the effects of quadratus lumborum block and lumbar erector spinae plane block on postoperative pain in hip and proximal femur surgeons.

Pain after hypospadias surgery is a challenging issue to solve for anesthesists. Many different analgesia techniques were defined in literature for this purpose. The investigators have implemented application of ultrasound guided dorsal penile nerve block into practice for these type of surgeries. Main purpose of this study is to compare the efficacy of nerve stimulator guided pudendal nerve block with ultrasound guided dorsal penile nerve block for postoperative analgesia after hypospadias surgery.

This is a multicenter, open-label study to evaluate the safety and PK of oral morphine sulfate in pediatric subjects with post-operative pain.

The study was planned to compare the effect of ketorolac 20 mg to 300 mg of paracetamol when added to lidocaine 3 mg/kg for Intravenous regional anaesthesia.

Post-operative pain following lumbar spine fusion is frequently difficult to manage and can lead to increased doses of opiate pain medications to control pain. In this study, the use of subcutaneous local anesthesia will be studied to determine its efficacy at reducing post-operative pain following spinal fusion surgery.

The nerves from lumbar plexus (LP) are the current target to achieve analgesia after a total hip arthroplasty (THA). Lumbar plexus block (LPB) is an alternative that provides optimal postoperative analgesia. However, many adverse effects and complications have been reported due to its proximity to vital structures. Because of these shortcomings, an alternative to block the LP nerves is required. In a recent trial suprainguinal Fascia Iliaca Block (SFIB) was reported to provide reliable analgesia in THA. SFIB may carry a lower risk profile, however, no study has compared the efficacy of LPB and SFIB in this setting. Thus, this randomized trial is set out to compare US guided LPB and SFIB for analgesia after THA. The hypothesis is that both blocks would result in similar postoperative opioid (morphine) consumption at 24 hours and, therefore, designed the study as an equivalence trial.

US-guided femoral nerve block is used effectively in post-operative pain management in the surgical treatment of the lower extremity. However, the volume and concentration of the local anesthetic drug to be administered remains controversial. In this prospective, randomized, double-blinded study, patients who underwent unilateral primary total knee arthroplasty and successfully performed spinal anesthesia with standard method and dosage, will be selected for US-guided femoral nerve block after the operation. Patients will be divided into three groups with simple randomization. The First group will be determined as the control group (GCont) and only dressing will be applied to the patients. For second group(G125), 0,125% 20 ml local anesthetic and for the third group (G25), 0,25% 10 ml local anesthetic will be administered to the femoral nerve without changing the drug dose (25 mg bupivacaine). Whether there is a difference between post-op analgesia durations, motor block formation, mobilization time and 90° flexion time between the groups will be investigated.

This research study is testing whether the local anesthetic lidocaine is as effective as ropivacaine for post-operative pain control in continuous thoracic paravertebral nerve blocks. Ropivacaine and Lidocaine are FDA-approved drugs that has been successfully used in this hospital for post-operative pain control for the past few years, thus has become the standard drugs used for this nerve block. Lidocaine has numerous potential advantages over ropivacaine, such as faster onset of action, better safety profile and greater anti-inflammatory action. Catheters placed near both sides of a patient's spine for postoperative pain control are called thoracic paravertebral nerve blocks and are a part of routine care. Through those catheters, a "numbing" medication, or local anesthetic, to block the transmission of pain from the surgical incision to the spinal cord, thus reducing pain. The research part of the study is whether subjects will receive either the local anesthetic lidocaine or ropivacaine. The goal of this study is to determine whether the lidocaine controls pain better and facilitates a faster recovery after abdominal surgery than ropivacaine. In this research study, the investigators will compare patient-reported pain scores, any additional pain medication requirements for adequate pain control, time it takes for bowel function to return to normal following surgery, as well as the incidence of any side effects, such as numbness and weakness, subjects may experience between those receiving lidocaine versus those receiving ropivacaine. The investigators will screen 100 patients and enroll 60 subjects into this study.

This is a randomized, double blind, placebo-controlled, parallel group, single-center study in approximately 560 subjects to determine the overall analgesic efficacy and safety of a fixed-dose ibuprofen 250 mg / acetaminophen 500 mg formulation compared to ibuprofen 250 mg alone, acetaminophen 650 mg alone, and to placebo. Subjects will be healthy males and females aged 18-40 years, inclusive, who are experiencing post-operative pain following surgical extraction of 3 or more third molar teeth. Following extraction, subjects must experience, within 5 hours, post-surgical pain of at least moderate severity (on a 4-point categorical scale), confirmed by a Visual Analog Pain Severity Rating Scale (VAS PSR) of at least 50 mm on a 100 mm VAS PSR scale. Eligible subjects will be randomized to receive a single oral dose of study medication under double-blind conditions and then evaluated on site for 12 hours following administration of study medication. Subjects will provide self-ratings of pain severity and pain relief at various time points using categorical and numerical scales. Additionally, subjects will also evaluate the time to first perceptible relief and time to meaningful relief using a double stopwatch method. Finally, at 12 hours, subjects will complete a categorical Global Evaluation of the study medication. A review of any reported adverse events will also be completed.
