Active clinical trials for "Pain, Postoperative"

Currently, the management of pain after cardiac surgery is based on the concept of multimodal analgesia: Combined use of non-opioid analgesics associated with morphine intravenous analgesia by a system controlled by the patient (patient-controlled analgesia-PCA). The combination of paracetamol and morphine PCA is very effective on pain at rest, but is limited on pain mobilization and causes the problem of side effects associated with opioid (overdose, sedation, respiratory depression, gastrointestinal intolerance, urinary retention ...) which are contributing factors to increase the length of stay in Intensive Care Unit, an additional cost of care and an increase postoperative morbidity and mortality. Methods that have proved their effectiveness on pain and mobilization used in postoperative cardiac surgery are: anti-inflammatory drugs (NSAIDs) and / or loco-regional analgesia techniques. NSAIDs enhance analgesia produced by PCA Morphine and allow a reduction in morphine consumption, improved postoperative pain, decreased sedation and decreased postoperative morbidity and mortality. Adverse effects of NSAIDs are commensurate with their time and exposure dose. Consequently, NSAIDs, in the absence of against-indications, should always be prescribed and used at the lowest effective dose and for the shortest possible time. Some studies have suggested that lower doses of NSAIDs didn't appear to affect their effectiveness. At present, the investigators have no studies that address the hypothesis from which minimum dose of ketoprofen analgesic effect is obtained. The investigators hypothesis is that lower dose ketoprofen may have efficacy on pain in the postoperative mobilization of cardiac surgery. The investigators want to find, in their study, this "optimal" ketoprofen dose which would be the minimum dose for clinical efficacy demonstrated dose. This optimal dose could reduce the number of adverse effects of NSAIDs, but their study will probably not have enough power to prove it. NSAID use at these low doses, in postoperative cardiac surgery, could be extended to patient populations most at risk or for a duration longer than 48 hours.

The investigators predict that giving patients paracetamol in the operative period will reduce their need for opioid pain reducers in the post operative setting.

Effective postoperative pain control is an essential component of surgery. Adequate analgesia improves patient comfort and satisfaction, thereby permitting earlier mobilisation, faster recovery and less likelihood of complications.The majority of surgeons will place 10ml of local anaesthetic into the breast pocket or inject it into the breast skin following breast surgery. A more specific technique is to identify the nerves supplying the breast and put the local anaesthetic directly around them (Pec block). This nerve block has recently been described and is increasingly being used by anaesthetists for surgery under local anaesthetic or for post-operative analgesia. It has been shown to provide better and more specific pain relief in several studies. Anaesthetists use an ultrasound machine to identify the anatomical landmarks for the nerves and they inject into the vicinity. They do not have direct vision and there is a risk of causing morbidity or the block not being effective. It is much easier for a surgeon to apply the block, as they can see the anatomical landmarks. Despite this, very few surgeons are aware of the technique. The study group consists of patients undergoing bilateral cosmetic breast surgery at BMI Edgbaston and Priory hospitals and Spire Parkway and Southbank hospitals in Birmingham and Worcester. If a patient consents to being involved in the research, they will have one breast randomised to receiving a pec block and the contralateral (opposite) breast will receive the same amount of local anaesthetic placed in the breast pocket in a non-targeted fashion. The patients and researcher will be blinded as to the allocation. Patients will complete a verbal numeric pain score for each breast at set intervals until they are discharged.In addition, the investigators will specifically ask which breast is the most painful at each time point. The results of the study may improve patient care.

A Comparison Between Lidocaine-Prilocaine Cream (EMLA) Application And wound Infiltration with Lidocaine For Post Caesarean Section Pain Relief : A Randomized Controlled Trial.

Post-operative pain after total knee arthroplasty is usually severe and impair the functional recovery of operated joints.The purpose of this study is to determine whether post-operative continuous femoral nerve block analgesia is superior to local wound infiltration combined with intravenous patient controlled analgesia in improving joint function and reducing the incidence of chronic post-surgical pain (CPSP).

The purpose of this study is to assess the efficacy of the hydrolocalization technique for placement of femoral perineural catheters in comparison with stimulating catheters. A non inferiority trial.

Extensive clinical studies have shown that intraoperative infusion high dose of remifentanil (0.2ug/kg/min) induced postoperative hyperalgesia. Recent experimental study however suggests that higher dose of remifentanil may attenuate postoperative hyperalgesia. Thus, the present study is designed as a "proof of principle" study and hypothesizes that higher dose of remifentanil may reduce postoperative pain in patients.

Objective of the study is to compare three different analgesic techniques in patients undergoing laparoscopic colon resections: peridural catheter, patient controlled analgesia of endovenous morphine and patient controlled analgesia of sufentanil sublingual tablets.

the aim of the study is to evaluate the effect of cryotherapy on postoperative pain in molar teeth with irreversible pulpitis and apical periodontitis

In this study, the investigator will examine the efficacy of Pericapsular nerve group (PENG) block in hip surgeries as a post-operative pain management technique in comparison with fascia Iliaca block in hip surgeries
