Active clinical trials for "Pain, Postoperative"

Primary Objective: To evaluate the pharmacokinetics (PK) of EXPAREL in pediatric subjects aged 6 to less than 17 years undergoing various types of surgeries. Secondary Objective: To evaluate the safety of EXPAREL in pediatric subjects aged 6 to less than 17 years undergoing various types of surgeries.

The study is performed in patients aged 5-18 years after thoracic surgery. The primary aim of this trial is to determine whether the use of gabapentin as a component of multimodal analgesic regiments reduces pain scores following thoracic surgery in pediatric patients. The secondary objective of the trial are to evaluate whether the use of gabapentin reduces postoperative anxiety scores and consumption of ropivacaine with fentanyl, decreases side-effects, and improves patient satisfaction.

The study was performed in patients aged 6-18 years after the Ravitch procedure and thoracotomy. The primary aim of the study was to evaluate the efficacy and safety of pain control provided by the multimodal approach that involves the continuous infusion ropivacaine with fentanyl vs. bupivacaine with fentanyl through thoracic epidural catheter. Secondary aims were to identify the determinants of acute post-operative pain at rest, during deep breathing and coughing.

Recent evidence has shown that the onset and intensity of post-operative pain are significantly related to the amount of residual pneumoperitoneum at the end of the surgical procedure. In addition, the use of low pressures of carbon dioxide (CO2) for induction of the pnemoperitoneum has been associated with a reduction in post-operative pain, probably due to a lower abdominal distension and a consequent reduced compression of the pelvic, abdominal and sub-diaphragmatic pain nerve fibers. The reduction of the residual pnemoperitoneum at the end of the surgical procedure could therefore play a key role in the reduction of post-operative pain, with consequent greater comfort for the patient and reduction of the use of analgesics. In view of the available evidence, the aim of the present study is to evaluate whether the application of Jackson-Pratt drain, for one hour from the end of the surgical procedure, can significantly reduce post-operative pain and the need of analgesics in patients undergoing laparoscopic gynecological surgery.

Post operative pain (POP) is a major obstacle on the road to healing, despite the increasing interest in postoperative pain management and development of pain control modalities (1). Postoperative pain is still insufficiently treated with more than 50% of patients suffering from moderate to severe pain early after surgery .Pain after orthopedic surgery is considered especially difficult to manage. Approximately half of total knee or hip arthroplasty patients present with extreme pain immediately after surgery. Total knee and hip arthroplasty often results not only in severe perioperative pain and debilitation, but chronic pain, joint stiffness, and functional disability many months or even years following the procedure. Various modalities of treating orthopedic POP exist, but the optimal management of postoperative pain remains controversial with no clear consensus of the best method.We suggest that acupuncture can be an effective treatment for post operative pain after total knee or hip arthroplasty.

Despite current available analgesic drugs, post-surgical pain management remains challenging. A potential new target for analgesic drugs are group-II metabotropic glutamate receptors subtypes (mGlu2 and mGlu3 receptors), since growing evidence from animal models show that activation of these receptors produce s analgesic effects in inflammatory and in neuropathic pain states. . N-Acetylcysteine (NAC) is a safe agent and with little to no side effects. NAC can induce analgesia by activating the glutamate:cystein antiporter, causing endogenous activation of the mGlu 2/3 receptors. However, this has only been investigated once in the peri-operative setting, were it showed preliminary promising result of reduction in opiate necessity. In healthy subjects there was a significant reduction in pain ratings to laser stimuli and amplitudes of laser evoked potentials after NAC. Based on these promising results, we hypothesize that pre emptive intravenous NAC can reduce postoperative pain and thereby cause less necessity for escape analgesics like opiates.

Environmental factors such as noise and light have been cited as important causes of sleep deprivation in Intensive care unit (ICU) patients. Previous studies demonstrated a hyperalgesic alteration in pain perception following a controlled sleep deprivation protocol. Another studies indicated that using eye masks can improve REM sleep in healthy subjects in simulated ICU environment, and improve sleep quality in ICU patients. This study aimed to determine the effects of using eye masks on sleep and thus on pain quality in postoperative cardiac surgery patients in ICU.

The purpose of this study was to evaluate the efficacy of dexamethasone when added to epidural bupivacaine on the duration of postoperative analgesia in patients underwent total knee replacement surgery.

The purpose of this study is to find out whether oral Naloxegol can reduce the side effects of opioid painkillers following surgery. This study aims to explore whether Naloxegol can similarly reduce opioid-induced side effects in post-surgical patients. About 130 surgery patients will participate in this study which is being conducted at Cleveland Clinic Main Campus.

In this single-centre, double-blinded, randomized controlled superiority trial, 189 participants having outpatient, arthroscopic shoulder surgery will be randomized into 3 equal sized groups. All participants will receive a standardized interscalene brachial plexus block and 4mg of dexamethasone or 50mcg of dexmedetomidine or both intravenously just prior to their surgery. The purpose of this study is to provide a head to head comparison of two types intravenous adjuncts to ISB, corticosteroids and alpha 2 agonists, and determine if their combination, or either one alone provides superior postoperative analgesia in arthroscopic shoulder surgery patients, as well as possibly show a synergistic relationship between the two adjuncts. The investigators hypothesize the combination of adjuncts will provide a longer duration of analgesia compared to either single agent.
