Active clinical trials for "Pain, Postoperative"

Pregabalin and dexmedetomidine have been introduced to manage postoperative pain. The present study aimed to evaluate the effect of the combination of two drugs on pain relief in patients undergoing total knee or hip arthroplasty under spinal anesthesia

The experience of pain derives from changes in brain excitability. Therefore, modulating the excitability of cortical areas involved in pain processing may become an attractive option in the context of multimodal analgesia during the postoperative period.

To access the analgesic efficacy of patient controlled thoracic paravertebral analgesia.

To compare the efficacy of intra-articular administration of neostigmine versus ketamine as adjuvant analgesics after knee arthroscopy.

This study aims to compare the effect of pre-operative oral pregabalin on post operative morphine consumption after abdominal hysterectomy with/without salpingo-oophorectomy.

The investigators aimed to evaluate the effect of ultrasound guided thoracic paravertebral block with bupivacaine on both perioperative anesthetic agent consumption and postoperative analgesia in pediatric patients undergoing percutaneous nephrolithotomy for kidney stone.

The goal of this study is to compare different ways of treating pain after surgery. This research study involves subjects who have a supracondylar elbow fracture and need surgery. This type of fracture occurs when the humerus (upper arm bone) is broken just above the elbow. Like any other surgery, you can expect that you will feel pain in the hours or days after the operation. Currently, despite the common occurrence of this surgery, there is not a standard way to treat and or prevent any of the pain afterwards. At this hospital, oral (take by mouth) pain medicine is commonly used to treat pain after this surgery. In this study, pain will be treated in one of the following ways: with oral pain medication with oral pain medicine and an intraarticular shot (a shot into the elbow joint) of bupivacaine (a "numbing" drug) or with oral pain medicine and an intraarticular shot of ropivacaine (another "numbing" drug). The shots will be given during surgery. Your participation will help us find out which of these three pain control methods works the best. The correct dosages of all drugs will be safely prescribed by the doctor on an individual basis and all drugs will be used under the careful watch of your attending physician. All the drugs used this study are approved by the FDA for use in adults but they are not specifically approved for use in children. However, nearly 7 out of every 10 drugs approved for adults are not specifically approved by the FDA for use in children. All drugs used in this study will be used in a way that is considered to be safe and reasonable by the Children's Hospital.

This was a randomized, double-blind, placebo-controlled study in subjects who underwent major surgery. Each subject's study participation consisted of a screening visit and a treatment period of up to 5 days. Following surgery (Day 0), subjects were randomly assigned to receive intranasal ketorolac 30 mg or intranasal placebo when the pain intensity (PI) rating equaled at least 40 mm on a 100-mm visual analog scale (VAS). Subjects received study drug every 8 hours for 48 hours and then 3 times daily for up to 5 calendar days in total; the frequency of dosing could be reduced after 48 hours. Starting at the time of the first dose of study drug and continuing for the first 48 hours after surgery, the subjects had access to morphine sulfate (MS) administered via patient controlled analgesia (PCA). After PCA was no longer required, backup pain relief was provided by another standard nonsteroidal anti-inflammatory drug (non-NSAID) analgesic regimen. If the subjects were discharged before postoperative Day 4, they could self-medicate at home through postoperative Day 4. A safety follow-up evaluation was conducted by telephone approximately 14 days after the end of dosing in a subset of subjects (n = 60). The primary objective was to evaluate the analgesic efficacy of multiple intranasal doses of ketorolac administered for up to 5 days. The secondary objective was to evaluate the safety and tolerability of this dosing regimen.

The purpose of this study is to evaluate the efficacy of periarticular injection with 0.25% bupivacaine for controlling pain after total knee replacement to improve the quality of post-operative care.

Recently, multimodal approach for postoperative pain control has been advocated.Combinations of traditional and novel pharmacological agents are administered, aiming to improve analgesia, spare opioid consumption, minimise adverse effects, and improve postoperative bowel function in colorectal surgery. One of the novel agents suggested is dexmedetomidine. It is a selective alpha-2 adrenoceptor agonist, which has been demonstrated to have anaesthetic, sedative and analgesic-sparing effects. Furthermore, a significant reduction in postoperative morphine consumption by using patient-controlled analgesia (PCA) has been achieved when dexmedetomidine was administered before operation. The drug also reduces cate-cholamine secretion, thereby reducing stress and leading to a modest reduction in heart rate and blood pressure, which may be particularly beneficial in patients with cardiovascular disease, while respiratory rate is not affected. In this study, the investigators would like to evaluate the analgesic effects of dexmedetomidine, which is administered intraoperatively with morphine, followed by postoperative PCA morphine infusion, for postoperative pain for open and laparoscopic colorectal surgery. Cyclooxy-genase-2 (COX-2) inhibitors and rescue intramuscular pethidine will also be incorporated as part of the multimodal analgesia regimens. Good pain control can help to decrease cardiovascular complications. Emerging data has suggested a key role of soluble CD40L as inflammatory mediators of atherosclerotic lesion progression. The investigators would like to evaluate the effect of our analgesic regimens on soluble CD40L peri-operatively. The investigators hypothesize that intraoperative dexmedetomidine can reduce postoperative pain and improve recovery and outcomes.
