Active clinical trials for "Pain, Postoperative"

The aim of the present study is to evaluate and compare the analgesic efficiency of the difference concentration between 0.125% and 0.25% bupivacaine provided by ultrasound guided posterior quadratus lumborum block undergoing LPEC in children

The prevalence of hip replacement surgery is increasing nowadays. Patients are usually older age and suffer from comorbidities may be an anesthetic and analgesic challenge. Erector spinae plane block (ESPB) is a newly described technique that is has been demonstrated in previous studies for chronic and acute pain treatment. The exact volume and concentration of local anesthetic (LA) to be used in ESPB is not well established.

The aim of this study is to compare the efficiency of serratus anterior plane block and erector spina plane block on analgesic consumption, postoperative pain and patient's satisfaction and recovery quality in patients undergoing mastectomy.

The concern for the opioid use in the total knee arthroplasty continues to rise in recent decades. Historically, the total knee arthroplasty consumed high doses opioids in the postoperative periods. Compared to the Opioid-Based patient controlled analgesia(PCA), the opioid-sparing protocol may have benefits to decrease the concerns of the opioid use and opioid-related complication and provides the equivalent efficacy for pain control. The purpose of this trial in to provide a novel opioid-sparing protocol (OSP) to evaluate the efficacy for pain control and reducing the immediate postoperative opioid consumption.

Postoperative surgical pain has been extensively study with regard to anaesthesia pain modalities, however little is published with regards to various arthroscopic shoulder surgical techniques. An intriguing characteristic of shoulder arthroscopy is the various arthroscopic pump pressures used by different surgeons. One could hypothesize that excessive water retention from the arthroscopic pump could causes excessive tissue pressure and swelling resulting in post operative pain. Unfortunately we could not find any literature in the English language regarding varying pressure pump settings on post operative pain control. For that reason we would like to assess how variable pump pressure effect tissue pressure over pre set time points, and how this may relate to post operative pain control.

Oxycodone is one of the most widely used opioids for pain treatment. Many studies demonstrated good efficacy of oxycodone on postoperative pain. In this study, we assess the efficacy and side effects of bolus intravenous of oxycodone injection compared to those of fentanyl in patients after total hip replacement surgery.

The primary objective of this study is to access the effect of Pectoral nerve I and II blocks in breast surgery as measured by consumption of postoperative morphine or its equivalent.

The aim of this study is to evaluate the effect of Vitamine C supplements to be helpful to reduce the postoperative pain after laparoscopic cholecystectomy through the double-blinded randomized controlled trial.

The purpose of this study is to test whether a dose of paracetamol given before surgical incision is more effective at reducing postoperative pain and analgesic consumption in cervical spine surgery versus a dose given at the end of surgery.

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).
