Active clinical trials for "Pain, Postoperative"

Laparoscopic Roux-en-Y gastric bypass (LRYGBP) is a common type of surgery in which length of stay and morbidity is intimately associated with post-operative nausea and vomiting (PONV) and recovery of bowel function. Medications most commonly used to control for post-operative pain are opioid medications, whose well known adverse effects include PONV. Currently, no studied adequate alternative to opiates exists for mild-moderate pain relief without the aforementioned risks. The primary goal for this study is to evaluate the the administration of pre- and post-operative IV acetaminophen to determine if there is in an overall decrease in the use of opioid analgesics by patient controlled analgesia (PCA) and subsequent decrease in subjective PONV leading to sooner return of bowel function, enabling progression to oral intake and decrease in post-operative length of stay.

This study will assess the efficacy and safety of levobupivacaine for postoperative pain control in patients received orthognathic surgery. In this split-mouth study, each side will be randomized to receive 1) 5ml 0.5% levobupivacine, 2) 2.5ml 0.5% levobupivacaine, or 3) placebo. One shot of these agents will be delivered by nerve block to maxillary and mandibular branches of trigeminal nerve before the incision was made. The degree of postoperative pain will be evaluated daily by visual analog scale for up to 3 days. The anticipated time on study is 1 year, and the target sample size is 40 individuals.

This prospective randomized study aims to evaluate the effectiveness of epidural injection of ropivacaine on the relief of pain in patients undergoing laminectomy. Total 60 patients will be randomized into one of two groups (groupC or groupI) based on Excel number generation. Patients in group C will receive no medication intraoperatively, and patients in group I will receive epidural injection of 0.1% ropivacaine 10ml before skin incision. Visual analogue scale pain scores, fentanyl consumption and the frequency at which patients pushed the button (FPB) of a patient-controlled analgesia system will be recorded at 4,12,24,48 hour postoperatively.

Pain is a common element of surgery. Opiates (morphine, oxycodone, hydrocodone, methadone, fentanyl) are very helpful in decreasing pain after surgery. Unfortunately, with repeated use opiates lose their effectiveness, such that patients need to utilize more opiates to achieve adequate pain relief - a phenomenon called tolerance. Sometimes tolerance to a pain reliever's effects can develop in just a few hours. It is thought that activation of the N-methyl d-aspartate (NMDA) receptor, a "switch" found on the surface of nerves, is partially responsible for opiate tolerance. Memantine is a medication that limits the activity of NMDA receptors in the brain and spinal cord. It has been used for years to help patients with Alzheimer's Disease. In this study, we will study the effects of memantine when combined with opiate medications to see whether it can increase the effectiveness of opiates for pain after surgery and reduce the side effects caused by opiates (e.g., sedation, nausea, itching).

Extended-release tramadol is indicated for the management of moderate to severe pain in adults who require around-the-clock treatment. It provides an extended duration of action, more constant plasma concentrations, a reduced dosing frequency, and the potential for improved compliance and therapeutic outcomes. The present study was designed to evaluate the safety and effectiveness of this medication in the treatment of early postoperative pain after knee arthroscopy.

Patients who undergo general anestheesia for total knee arthroplasty pften have sever postoperative pain which hinders their rehabilitation. Nitroglycerin patches have been found to cause alleviation of pain especially when used in conjuction with morphine. Therefore we propose placement of a nitroglycerin patch after total kneee arthroplasty surgery and see how it affects pain scores or causes less nedd for morphine after surgery.

Ultrasound-guided combined thoracic segmental spinal epidural anesthesia in comparison with general anesthesia in upper abdominal and breast surgery.

This interventional double-blind randomized controlled study was carried out on 60 cases underwent elective caesarean section delivery, they were divided into 2 groups; patients were randomly allocated into two equal groups; Group M: received intrathecal 150 microgram morphine in a 0.5 ml volume, mixed with 10 mg of hyperbaric bupivacaine 0.5 % in a 2 ml volume (total volume 2.5 ml). Group B: received intrathecal 10 mg hyperbaric bupivacaine 0.5% 2ml volume + 0.5 saline (Total volume 3ml) and at the end of surgery patient received bilateral TAP block with 20 ml volume of 0.25% bupivacaine on each side.

More than half of the patients suffer from intensive pain 1-2 days after arthroscopy in the knee. Walking function and physical activities are affected by this intensive pain although local anaesthetic is given in the joint and soft tissue. The patients are often discharged on the same day as the arthroscopy takes place depending on their ability to walk with or without assistive technology. It is a well-known fact that the patient is given a dose of morphine, analgesics or an ice pack on a painful knee to reduce pain intensity. The aim of the project is to study whether pain intensity and analgesics can be additionally reduced by giving local anaesthetic by means of an adhesive tape placed on the skin instead of giving morphine, analgesics or ice pack on a painful knee. The researchers plan to include a cohort of 180 patients: 60 patients having a meniscus sutured, 60 patients having meniscus tissue removed surgically, 60 patients having mucous fold removed surgically. This study is planned to be a pilot study in order to complete a future large medical science study.

This study compares post-operative incisional pain on post-operative days 1 and 7 who will undergo gynecologic laparoscopic operations. Half of participants will undergo conventional fascial closure, while the other will undergo fascial closure by Berci Fascial Closure (Karl Storz, Belgium).
