Active clinical trials for "Pain, Postoperative"

The aim of this randomized clinical trial was to compare the potential effects of resin-based and bio ceramic sealers on the occurrence and intensity of postoperative pain in patients with asymptomatic apical periodontitis (AAP) .

Total knee arthroplasty (TKA) is one the most common surgical treatments performed for end stage degenerative arthritis of the knee. More than 700,000 procedures are currently performed yearly in the United States. This procedure usually results in moderate-to-severe pain in the immediate post-operative period. Optimal pain control may allow early mobilization, accelerate rehabilitation, improve patient satisfaction, decrease length-of-stay, and optimize functional outcomes. The challenge, however, is to manage pain with alternative methods, reducing the role of opiate medications, which are highly addictive with myriad side effects. In this prospective randomized double-blinded controlled study, the investigators aim to evaluate the benefits of an over-the-counter (OTC) transdermal CBD preparation in patients undergoing primary total knee arthroplasty as a novel adjunct to the standard multi-modal analgesic regimen, to reduce postoperative pain and reduce the need for opiates after total knee arthroplasty.

To compare the incidence of post-operative pain after single-visit versus two-visit non-surgical endodontic retreatment.

In humans and animals, circadian rhythm sleep cycle plays an important role on maintaining and regulating basic physiological homeostasis, such as cognitive function, glucose metabolism, memory consolidation, immune function and growth hormone secretion. The induction of general anesthesia leads to a state of reduced responsiveness, which is often described by anesthesiologists and patients as "sleep". This seems to be a common problem in the case of patients under general anesthesia, besides surgery trauma and general anesthetics may change sleep function and sleep cycle perioperatively, the postoperative complications such as pain, nausea and vomiting etc after general anesthesia may also reduce postoperative sleep quality.Flurbiprofen axetil is a new non-steroidal anti infection analgesic(NSAIDs), which is widely used for analgesia to reduce the dose of opioids and the occurrence of adverse reactions, such as declined sleep quality, respiratory depression, nausea and vomiting . Preemptive analgesia is an analgesic intervention that begins before surgery to prevent the nervous system from becoming sensitive to subsequent stimuli that may aggravate pain. A large number of experimental studies have shown that use flurbiprofen axetil preoperatively is better than use it postoperatively. However, limited information was reported before on the effect of factors such as age, gender, preoperative negative mood such as anxiety and depression, type and length of surgery, which could influence postoperative pain and analgesic consumption and the association between postoperative sleep quality and postoperative pain intensity. At present, there has been less previous evidence for how preemptive analgesic with flurbiprofen axetil affect postoperative sleep quality through its effect on postoperative pain of patients with different sex under general anesthesia.

Laparoscopic cholecystectomy (LC) is a minimally invasive surgical procedure that causes moderate pain in the early postoperative period. In this prospective randomized study, the efficacy of four-quadrant and two-quadrant laparoscopic-assisted transversus abdominis plane (LTAP) block on postoperative pain will be compared with that of only intravenous analgesia (SA) and port-site infiltration of local anesthetic (LA). Patients undergoing elective LC will be divided into four groups of 40 patients each using a randomization scale. The standard analgesia group will receive LTAP block with normal saline (NS) and port-site infiltration of NS, the LA group will receive LTAP block with NS and port-site infiltration of bupivacaine, while the four and two quadrant LTAP group will receive the block with bupivacaine and port-site infiltration of NS. Postoperative analgesia will be administered to all groups as a standard procedure. The patients' demographic data, postoperative 1, 3, 6, 12, and 24-hour visual analog pain (VAS) scores at rest and on cough, opioid requirement, presence of nausea and vomiting, and satisfaction scores will record in a standard form. The statistical analysis will be carried out using the SPSS software and the level of significance was set at p<0.05.

The aim of this study is to clinically compare the efficacy of intraoral cryotherapy versus intracanal cryotherapy after single visit root canal therapy in lower molars with irreversible pulpitis and symptomatic apical periodontitis

Video assisted thoracoscopic surgery (VATS) is a type of minimally invasive thoracic surgery (MITS) procedure used for diagnosis or treatment of chest pathologies (pulmonary, mediastinal, chest wall). Most main procedures traditionally performed by open thoracotomy can be performed with smaller incisions using video support. While being less invasive in comparison to open surgery options, thoracoscopic surgery may damage the intercostal nerve and damages muscles. Also it provokes soft tissue edema at the incision area. Therefore, pain can be more intense than expected after thoracoscopic procedures. Post-operation pain is not just an acute problem; 20% of the patients develop chronic incision pain after a thoracic surgery. particiants hypothesis is that continue ESP block catheter application is non-inferior than epidural catheter application in the first post-operative 48 hours regarding post-operative pain relief. The purpose of this study is to invertigate the effects of TEA and ESPB on post-operative pain in patients undergoing VATS.

This study aims at comparing the effects of bilateral ultrasound-guided quadratus lumborum block versus lumbar epidural block on postoperative analgesia and inflammatory response following major lower abdominal cancer surgery.

Lumbar vertebra surgery is one of the most common surgical procedures. After lumbar veretebra surgery, patients complain of excessive pain. Postoperative pain usually occurs in the early postoperative period and delays patient mobilization and thus lengthens hospital stay. The aim of this study was to compare the efficacy of erector spina plan(ESP) block and thoraco lumbar interfacial(TLIP) block on postoperative pain in patients with spinal surgery.

The lidocaine patch is currently only permitted for postherpetic neuralgia but we want to investigate its effectiveness in post operative pain after inguinal herniorrhaphy
