Active clinical trials for "Pain, Postoperative"

Obesity has become one of the world's leading health problems. It is known that obesity causes many diseases and negatively affects the quality of life. For this reason, many conditions that are thought to be effective in obesity and concern the quality of life of patients have been scientifically researched and continue to be investigated. One of them is postoperative pain. Although there are studies stating that there is no relationship between body mass index (BMI) and postoperative pain, when the literature data is examined, it is thought that obesity is a risk factor for postoperative pain and changes pain sensitivity and analgesic needs of patients. There are also studies in the literature stating that the level of postoperative pain increases in parallel with each unit increase in BMI. After thoracic surgery, many analgesic methods have been suggested, including thoracic epidural analgesia (TEA), thoracic paravertebral block (TPVB), intercostal nerve blocks (ICSB), erector spina plane block (ESPB), serratus anterior plane block (SAPB). This study will compare the effects of BMI on postoperative pain in patients undergoing TPVB for postoperative analgesia and thoracoscopic surgery.

Newborn infants experience pain after surgical procedures,prevention and management of pain in neonates is important due to its deleterious consequences. Fentanyl is a widely used analgesic which promotes rapid analgesia,however, is not free of adverse effects including chest wall rigidity, hypothermia, hypotension, respiratory depression and tolerance.Dexmedetomidine is a selective α 2-adrenergic agonist can cause sedation, anxiolysis, analgesia and minimal respiratory depression.Therefore, the objective of the study is to evaluate the safety and efficacy of dexmedetomidine compared to fentanyl in postoperative mechanically ventilated neonates.

The purpose of this study is to evaluate the effect of pain relief after infusion of ropivacaine at port sites at end of laparoscopic cholecystectomy (LC)compared with placebo (0.9% normal saline).

The investigators designed a randomized double-blind placebo-controlled trial to evaluate the effect of preoperative single dose of oral melatonin and vitamin C administration on postoperative analgesia in patients undergoing elective major abdominal surgery.

Animal studies have shown that the level of pain sensitivity is highly dependent on the amount of polyamines in food. This fundamental observation of a nutritional approach to pain led the authors to develop diets completely depleted in polyamines whose anti-nociceptive properties have been confirmed in animals. Postoperative pain after foot surgery are currently fairly well controlled but at the cost of a high consumption of grade II analgesics which is associated with a high rate of side effects (nausea, vomiting ...). The investigators' hypothesis is that a diet low in polyamines may have an additive effect on pain control and reduce the consumption of level 2 analgesics. The objective of this study is to show the efficacy of a polyamines-poor diet on postoperative pain in ambulatory surgery of the foot.

The TAP is a space between the muscle layers of the abdominal wall that houses nerves supplying the abdominal skin. Injecting the local anesthetic ropivacaine into this space will block these nerves and prevent pain following c-section. The investigators will compare two different approaches to injecting the local anesthetic in this space. Conventionally, the block is done after surgery is completed and the abdomen is closed. The anesthesiologist introduces a needle through the abdominal wall skin under ultrasound guidance to reach the TAP space and the drug is injected. Since the TAP layer is one of the deeper layers of the abdominal (belly) wall and is closer to the inside of the abdomen than to the outside (skin), injecting from the inner aspect of the abdominal wall during the surgery is easier and quicker to perform than the conventional block and does not require ultrasound guidance as there is no risk of injury to abdominal organs like the liver. With this research the investigators attempt to prove that surgically administered TAP blocks take 25% less time to perform compared to the conventionally administered TAP block for post cesarean section pain relief. Surgical TAP blocks are also more cost-effective as in addition to reduced OR time, they are safer and do not require skilled operator and specialized equipment. Secondary outcomes will include total time spent in the Operating room, presence and severity of postoperative pain, time to first request for pain medication, total postoperative narcotic consumption in 48 hours after surgery and side effects.

The primary objective of this study is to evaluate the analgesic efficacy of N1539 in subjects with acute moderate to severe pain following unilateral bunionectomy.

The aim of this study was to investigate if using lasers instead of scalpel for flap advancement in bone augmentation procedures would reduce post-operative swelling and pain.

Thoracotomy is one of the most painful surgical incision. Uncontrolled acute post-thoracotomy pain reducing deep breathing exercises and secretion clearance increased the incidence of postoperative pulmonary complications including atelectasis, hypoxemia, and postoperative pulmonary infections. Thus, an effective analgesia is crucial in order to reduce perioperative morbidity and hospitalization time and also to prevent chronic post-thoracotomy pain. Thoracic epidural analgesia and thoracic paravertebral analgesia are currently the standard strategies for thoracic surgery but the difficult of performing them in all patients and their potential complications are all factors that limit their use. Systemic administration of opioids is the simplest and common strategy to provide analgesia but it may be associated with several undesirable effects, such as respiratory depression, sedation, nausea, constipation and vomiting. In the recent years, preventive analgesia is become one of the most promising strategy of postoperative pain control. It is based on the concept of administering analgesic drugs before the occurrence of nociceptive input in order to prevent central sensitization. The efficacy of preemptive analgesia is unclear and there is no a consensus on its efficacy on controlling pain after thoracic procedure. Pain following thoracotomy has a multifactorial genesis including surgical incision, intercostal nerve injury, pleural inflammation, and damage of pulmonary parenchyma and of diaphragm. Thus, a multimodal analgesia that intercepts the signalizing at numerous locations could be more effective than a single strategy targeting one site along the pain pathway. Thus, in the present study, the clinical hypothesis was that the preemptive analgesia of the skin using a new tool as the Lidocaine patch 5% would improve the analgesic effects of systemic morphine analgesia for controlling post-operative pain following thoracotomy.

Dexamethasone has an evidence-based indication in postoperative emesis prophylaxy and as a antiinflammatory steroid. Although the perineural administration is off-label, several studies recognised its analgetic action as an adjuvant for peripheral nerves blockade, permitting to reduce the concentration of the local anesthetics and extending the sensory and motor block.Questions remain concerning the mechanism of action, optimal dose, the lack/degree of toxicity and the comparison with intravenous administration.The aim of this prospective randomized controlled study is to investigate the efficacy of analgesia with 4 mg or 2 mg Dexamethasone added to a combination of ropivacaine 0,5% and lidocaine 1% in vertical infraclavicular blockade (VIB) anesthesia for upper limb surgery.
