Active clinical trials for "Pain, Postoperative"

The aim of the study is to determine which regional anaesthesiological technique (thoracic epidural analgesia or paravertebral block) is more suitable for thoracic surgery

To validate the efficacy of miniaturized ultrasound needle transducer as the primary guide for thoracic regional anesthesia.

The purpose of this study is to evaluate the effects of topiramate (TPM) in obese patients with respect to weight loss and pain after total joint replacement surgery

Chronic postsurgical pain following lung cancer surgery is common with and 20-60 % develop chronic pain which persists more than six months after surgery. Causes and health impact of this pain have been comprehensively studied. Current treatment consists of combination of pain medication, physiotherapy and psychological therapy. Botulinum Toxin A (BTX-A) has shown promising effects in a variety of chronic postsurgical pain syndromes. The use of BTX-A in lung cancer patients has only been presented in few case reports. No randomized controlled trials (RCT) have been executed to date. Study objectives: Determine recruitment potential among cured lung cancer patients with chronic postsurgical pain for an RCT and if the method of BTX-A administration is feasible and acceptable. Further more, this study will contribute to the stage testing of the hypothesis that chronic pain following thoracic surgery can be treated with BTX-A. Methods: Recruitment of test subjects: Participiants are recruited among former lung cancer patients with chronic postsurgical pain, who have undergone radical treatment for lung cancer at the Department of Cardiothoracic Surgery, Aalborg University Hospital. Potential test subjects are invited by mail / e-mail. Randomization and blinding: Participants are randomized to receive a single series of subcutaneous injections with either Onabotulinum Toxin A (active agent) or inactive normal saline (Placebo) at the former operation site. Neither participant nor investigator will know which treatment is given until the end of the trial. Data collection: Data is collected by questionnaires delivered and answered by mail or digitally. Data on the possible effects and possible adverse reactions are collected at multiple times until three months after treatment.

Removal of impacted lower third molar teeth is one of the most common oral surgical procedures, and these operations often lead to various complications in patients. Antibiotics, analgesics and/or anti-inflammatory drugs are prescribed for the treatment of complications encountered. Anti-inflammatory is the property of a substance or treatment that reduces inflammation or swelling. Anti-inflammatory drugs make up about half of analgesics, remedying pain by reducing inflammation as opposed to opioids, which affect the central nervous system to block pain signaling to the brain. Based on this information, in this study, it is aimed to evaluate the effects of deflazacort preoperatively on the postoperative pain, swelling and trismus.

Transversus Abdomens Plance (TAP) block is commonly used to control pain in laparoscopic procedures. It is usually administered with ultrasound guide but it can be also administered with laparoscopic assistance under direct visualization. Aim of the present study is determining if the lap-assisted TAP is superior to the us-guided TAP Block in pain control in the immediate postoperative phase as well at 1 and 6 hours post surgery.

Chronic postsurgical pain (CPSP) refers to pain that occurs or increases after surgery and lasts longer than 3 months. Severe postoperative acute pain is one of the major risk factors of CPSP. Spine surgery brings severe postoperative pain due to large trauma and long duration. Ketamine and esketamine are N-methyl-D-aspartate receptor antagonists; they have anti-hyperalgesic effects and may reduce CPSP. Dexmedetomidine is an alpha 2-adrenoceptor agonist with sedative, anxiolytic, and analgesic effect; it is frequently used as an adjuvant to postoperative analgesia. In a previous trial of the investigators, 200 patients following scoliosis correction surgery were randomzied to receive opioid analgsia supplemented with either mini-dose esketamine-dexmedetomidine combination or placebo. The results showed that esketamine-dexmedetomidine supplement analgesia significantly improved analgesia and sleep quality after surgery. This study is designed to test the hypothesis that mini-dose esketamine-dexmedetomidine supplemented analgesia may reduce CPSP at 2 years after scoliosis correction surgery.

Modern postoperative pain management aims to optimizing pain relief while minimizing opiate usage. While opiates are effective for pain relief, they result in common adverse effects such as nausea, constipation, and urinary retention, and most importantly present a long-term risk of abuse and dependency. Commonly used approaches include non-opiate pain medications such as acetominophen and non-steroidal anti-inflammatory agents, as well as regional nerve blocks such as epidurals. The transversus abdominis plane (TAP) block is a fascial plane block performed by injecting local anesthetic into the plane superficial to the transversus abdominis muscle where the anterior rami of the spinal nerves course to provide sensory innervation to the abdominal wall. The injections are generally placed either subcostally or at the midaxillary line bilaterally. The TAP block has been shown to be effective in reducing pain scores and opiate usage in some randomized studies but not others in patients undergoing various abdominal surgeries. There is great variation in method of administration, sites injected, and local anesthetics used, which may in part account for the heterogeneity of trial results.

The goal of this randomized, double blinded study is to examine in children whether postoperative agitation can be reduced. The main question it aims to answer is Will optimized, monitor guided analgesic treatment and dexmedetomidine reduce postoperative agitation Participants will receive a standard anaesthesia regimen and on top of that, a titrable remifentanil infusion guided via Mdoloris Anastasia nociception index (ANI) monitor will be added. Additionally, the patients will receive either bolus placebo or bolus dexmedetomidine. The postoperative agitation measured via the Richmond agitation and sedation scale (RASS) score, will be compared. Secondary outcome measures including carbon dioxide trends will be made.

Appendicitis is a common pathology and the one of the most common surgical procedures performed in France. Young subjects are the most frequent patients with appendicitis. Appendicular peritonitis increases post-operative pain, morbidity, and the average length of hospital stay compared to uncomplicated appendicitis. Pain alters perioeprative rehabilitation of patients. Surgery, performed urgently, generates more anxiety and pain than scheduled surgery. But, intensity of chronic postoperative pain is in correlation to intensity of acute postoperative pain. In addition, admission of emergency cases is more axiety-inducing, due to wait times, packed emergency room, worklaod of medical staff. Sex and age also modify perception of postoperative pain. Adults under 50 feel more pain than older patients for similar procedures. Medication for pain is required in perioperative period et is administered according protocol of each medical center ; these protocols include analgesics, opioids or not, benzodiazepine... However, opioids analgesic (example: morphine) can induce side effect, such as confusional syndrome, cardio-pulmonary manifestations, ileus, nausea and vomiting... Non-pharmacological approaches have been also proposed to reduce anxiety and pain. Hypnosis is frequently used but not always adapted to the emergency: need for qualified and available staff, environment not conducive to hypnotic induction... Hypnosis is a modified state of consciousness ; it is neither a state of vigilance nor a state of sleep. Several types of hypnosis can be distinguished according to the medical application, such as hypnoanalgesia or hypnosedation. Using hypnosedation during surgical or invasive procedure can reduce the use of painkillers and sedatives. Interest of hypnosis has been observed for extraction of wisdow teeth, delivery... Young patients are very comfortable with the use of their smartphone which is often the first object recovered when they return from the operating room. Many hypnosis videos are available free of charge on Internet, and some of which are produced by specialized practitioners and university teachers. A recent study has shown that among young people, addiction to smartphone is a predisposition to hypnosis. However, the use of hypnosis videos on smartphone has never been studied for the control of postoperative pain.
