Active clinical trials for "Pain, Postoperative"

The aim of this study is to document the perioperative opioid use and its safety in the UK and countries in Europe and to describe its association with surgical complications, persistent pain and quality of life. In an international, prospective, observational cohort study, data about the perioperative pain management will be collected in all eligible hospitalised adult patients who undergo surgery in a designated "study week" in as many hospitals as possible in Europe. Baseline data will be collected, and participants followed up at one week, and at three and twelve months post-operatively. The primary outcome will be opioid use at three months after surgery. Secondary outcomes will include opioid use during the preoperative month (preoperative use), during surgery and up to one week after surgery (or discharge, whichever is earlier), and up to the end of the postoperative year. Additional secondary outcomes are the incidence of preoperative pain, persistent pain with/without the presence of neuropathic components, quality of life and surgical complications. The potential association between opioid use and pain outcomes will be investigated. This study could help to develop strategies to improve quality of care, through pain management, for patients undergoing surgery.

The goal of this observational study is to describe the influence of renal function on the pharmacokinetics of methadone used through an intravenous patient-controlled analgesia (IV-PCA) pump for the management of acute postoperative pain. The main question it aims to answer is: • Is the pharmacokinetic of methadone used in an IV-PCA pump impaired in patients with chronic kidney disease? After surgery the participants will use an IV-PCA of methadone and blood samples will be withdrawn to measure the plasmatic levels of it.

An alternate perioperative pain control protocol composed of intravenous ketorolac and oral acetaminophen for patients who underwent total knee replacement was designed with the aim to determine its efficacy when compared to pain control with intravenous morphine and oral oxycodone combined with acetaminophen. In addition, the study will evaluate the differences and similarities in the Hispanic population that could predict protocol efficacy.

Irrigation activation in endodontics is considered now a very important step for the success of root canal treatment. In this study, the investigator will examine the effect of two recent activation systems ( XP-endo Finisher file and the new sonic EDDY system) in comparison with the conventional needle irrigation on irrigant penetration depth into root canals using radiopaque contrast media and digital radiography and on the postoperative pain after single-visit endodontic treatment using a visual analog scale.

Video-assisted thoracic surgery (VATS) has become a common procedure in thoracic surgery. Severe postoperative pain may be encountered in patients undergoing VATS. Analgesic methods such as thoracic paravertebral block (TPVB), intercostal block, serratus anterior plane block (SAPB), and erector spinae plane block (ESPB) are widely used for VATS. Among these methods, ultrasound (US) guided TPVB is the most preferred method. In recent years, the frequency of application of plane blocks as a component of multimodal analgesia has been increased. ESPB and SAPB are some of them. There are two techniques for SAPB application. In Deep SAPB (DSAPB) application, a local anesthetic agent is given under the serratus anterior muscle. In the Superficial SAPB (SSAPB) application, the local anesthetic agent is given above the serratus anterior muscle. Since it is done by entering from the same point in two applications, it is possible to perform these two applications at the same time with a single needle entry. The mechanisms of regional analgesia techniques used after thoracic surgery operations are also different from each other. Therefore, it may be possible to obtain a more effective analgesic effect in patients by combining the mechanism of action of DSAPB and SSAPB, as in the multimodal analgesia method. This study seeks to evaluate the effect of TPVB and combined SAPB (CSAPB) after VATS.

Approximately 1 in 5 women who undergo CS will experience severe acute postoperative pain. The severity of pain in the acute postoperative period is a significant predictor for the development of chronic pain, which occurs in 9.2%-18% of women who undergo CS. Furthermore, severe acute post-cesarean pain triples a woman's risk of developing postpartum depression and negatively affects breastfeeding and infant care. For these reasons, it is imperative to provide adequate postoperative analgesia in this patient population

Chronic pain after thoracic surgery has been a bothering problem since the era of thoracotomy. The prevalence of chronic pain no matter in thoracotomy or video-assisted thoracoscopic surgery is about 30 to 47%. Better acute pain control after thoracic surgery has been assumed to be an effective way for prevention of chronic pain. Especially in this extreme minimal invasive surgery, uniportal video-assisted thoracic surgery, more optimized perioperative analgesics should be found out. In the guideline of "enhanced recovery after surgery", less opioid is suggested. Other than opioids, there are just few parental analgesics could be used, like acetaminophen or cyclooxygenase-2(COX-2) inhibitor. In our study, the investigators would like to build up a better analgesic strategy for uniportal video-assisted thoracoscopic surgery with less opioid and less side effects.

Postoperative opioid-centric pain management strategies in obese patients are accompanied by the possible development of; opioid-induced ventilatory impairment (OIVI) and hypoxemia. This presents as sedation and respiratory depression, combined with upper airway obstruction and hypercapnia. If it remains undetected and untreated, it can result in increased perioperative morbidity and mortality.Thus, an increased interest in the use of non-opioid analgesic adjuncts has been prompted. Intra-operative intravenous lidocaine infusion has analgesic, anti-inflammatory, anti-hyperalgesic, opioid-sparing effects with an enhanced recovery after surgery (ERAS) profile. Its postoperative analgesia may last after reduction of its plasma concentration. So, lidocaine could be a good alternative in bariatric surgery. Lidocaine has been studied as part of an opioid-free multimodal analgesia in morbidly obese patients. Also, its use in bariatric surgery showed a decrease in postoperative opioid use and improvement in the quality of recovery.

Rationale: Surgical trauma and post-surgical pain induce a physiological stress response that can be detrimental to the patient. Non-pharmacological interventions aimed at stress reduction are known to reduce pain scores and opioid consumption. The effect of these interventions on the surgical stress response are unknown. Objective: To assess the effect of a bundle of non-pharmacological interventions implemented in the post-anesthesia care unit on the total serum cortisol levels after intermediate and major surgery. Study design: This is a prospective before-after study. Study population: Patients scheduled for intermediate or major oncological surgery in a tertiary referral cancer center. Intervention: The implementation of a bundle of four non-pharmacological interventions aimed at stress reduction in the post-anesthesia care unit. The bundle consists of: access to music, aromatherapy, natural images on the walls and ceiling and communication techniques aimed at reduction of stress and pain. Main study parameters/endpoints: Serum cortisol levels on the first postoperative day.

Patients who have undergone laparotomies often require multimodal postoperative pain regimes. In recent years, abdominal wall blocks have been included to become part of this in order to overcome side effects of systemic opioids and complications from epidural analgesia. Borglum popularised a new approach on abdominal wall blocks by introducing the transmuscular quadratus lumborum (QL) block. Transmuscular QL block is thought to be effective against somatic and visceral pain as local anaesthetic tends to spread from the site of injection to thoracic paravertebral spaces where the sympathetic chain lies. The objective of this study is to evaluate the analgesic efficacy of transmuscular QL block in patients undergoing total abdominal hysterectomy (TAH) by measuring cumulative opioid consumption, pain score at rest and on movement 24 hours after TAH. Our hypothesis is patients given transmuscular QL block will have lower cumulative opioid consumption.
