Active clinical trials for "Pain, Postoperative"

To determine the effect of combined intracutaneous infiltration and intraperitoneal instillation of 80 mL 0,125% levobupivacaine prior to the start of laparoscopic cholecystectomy on abdominal pain up to 24 hours after surgery.

This study has been designed to determine if women undergoing cesarean delivery with spinal anesthesia and routine pain management who also have an additional ultrasound guided transversus abdominis plane (TAP)block using ropivacaine have better pain relief and a better quality of recovery than women who don't have the additional TAP block. Maximizing pain relief using ultrasound guided TAP blocks in addition to neuraxial opioids, NSAIDs, and acetaminophen may improve acute pain outcomes, reduce adverse side effects, and potentially reduce chronic pain.

Adequate postoperative analgesia can facilitate recovery following gastric bypass surgery for morbid obesity. The efficacy and safety of intravenous patient - controlled analgesia has been studied, but up to date no data are available concerning the use of thoracic epidural patient-controlled analgesia regarding the use of levobupivacaine combined with morphine in morbidly obese patients. The investigators' aim in this prospective, randomized, double-blinded study was to compare the analgesic effectiveness, the dose requirements and side effects of thoracic epidural patient controlled analgesia 0.1% and 0.2% levobupivacaine combined with a continuous epidural administration of morphine, with or without a loading dose, after open gastric bypass for morbid obesity.

This study is a blinded randomised study of slow release levobupivacaine vs saline for women undergoing day case operative pelvic laparoscopy. Participants will be randomly given either saline or levobupivacaine and efficacy will be measured using ranked ordinal pain scales and rescue oral analgesia use.

Pain is a major problem after TKA, especially in patients with high pain catastrophizing. Newer MR-scan studies indicate that Escitalopram may have an immediate cognitive and emotional effect. The investigators therefore investigate the effect of Escitalopram as a perioperative analgesic.

The impact of anaesthetic method (intravenous vs. inhalational) has been proposed, but not proven in a large-scale study. The researchers aim to provide an investigation that has sufficient power to clarify the potential effect of anaesthetic method on postoperative need of opioids. Sevoflurane and propofol will be compared.

In this study the investigators wish to compare the effect of a selective axillary nerve block to placebo in patients undergoing arthroscopic shoulder surgery. It is the investigators hypothesis that the amount of morphine consumption in the first 4 hours postoperatively in the intervention group will be significant lower than in the placebo group.

Low dose sub-anaesthetic dose of ketamine has been shown to reduce postoperative pain and analgesic consumption. However, due to the heterogeneous results, the standard dosing regimen has not been available. Recently, its effect in postoperative outcomes and the development of post-operative surgical pain has also been suggested. Ketamine has been shown to reduce post-operative early inflammation especially serum IL-6. Therefore, study in its effects in post- operative pain and outcomes due to inflammation is suggested. Only few clinical studies assessed post-operative pain are related to inflammation. Pain after third molar surgery is a good model of postoperative acute inflammatory pain. A previous study showed that there was no benefit to administer ketamine before or after oral surgery for pain relief. However, other studies demonstrated that ketamine used as sedative or local ketamine in third molar surgery could reduce postoperative dental pain, swelling and trismus. Postsurgical facial oedema is difficult to quantify accurately as it is three dimensional. Over the years, various measurement techniques have been tried to measure oedema objectively. These include direct linear measurement using tape or flexible rulers across fixed soft tissue landmarks, standardized stereophotographic measurements, computerized tomography (CT), magnetic resonance imaging (MRI), ultrasonography (US) and three - dimensional (3D) laser scanning. Recently, three dimensional image reconstructions using a reversed engineering technique has been developed and is used in the manufacturing industry. This technology could be applied in a clinical setting for monitoring soft tissue changes. In this study, the investigators will aim to study the use of sub-anaesthetic dose of ketamine in post-operative dental pain and recovery outcomes. The investigators hypothesise that post-operative pain after Bilateral Third Molar under General Anaesthesia is less in patients receiving sub-anaesthetic does of ketamine before incision. The magnitude of this effect will be compared with a positive control group (dexamethasone) as well as a placebo group (normal saline). Further, the investigators aim to demonstrate whether ketamine can reduce post-operative facial oedema and other post-operative outcomes.

To compare the incidence and severity of nausea in the study treatment groups, during the 18-hour period starting 6 hours after titration to pain relief; following confirmation of the assumption of non-inferiority between the two groups of pain relief over the 24 hour post-operative period. Pain relief and nausea will be determined by measuring the areas under the curves of pain intensity and nausea verbal rating scale scores.

Aim of the study is to compare efficacy and safety of YM177 with placebo and etodolac in patients with postoperative pain.
