Active clinical trials for "Pain, Postoperative"

The aim of our study is to define the median effective analgesic doses (ED50) of paracetamol, morphine, and their combination and determination the nature of their interaction administered IV for postoperative pain after moderate painful surgery using up-and-down and isobolographic methods.

The purpose of this study is to assess the effects of dexmedetomidine while patients undergo treatment for Interstitial Cystitis (IC). The investigators goal is to demonstrate in patients with IC undergoing bladder hydrodistension that the use of dexmedetomidine as a supplemental anesthetic agent will result in better postoperative pain management.

The purpose of this study is to evaluate the safety, efficacy, hemodynamic and respiratory stability of a low-dose of dexmedetomidine infusion in post-operative surgical in-patients undergoing thoracic surgery after discharge from PACU or ICU.

The purpose of this study is to determine the effect of pain relief with AeroLEF in adult patients, following orthopedic surgery.

The management of post-operative pain in patients after vaginal surgery provides many unforeseen challenges. Although vaginal surgery is considered a minimally invasive approach for the repair of pelvic floor prolapse and urinary incontinence, patients may still experience varying degrees of discomfort and post-operative pain. Narcotics, however, can introduce a host of problems in addition to the potential addictive properties of the medication. A vicious cycle ensues as patients seek better pain control at the expense of worsening constipation, but without adequate control of pain after surgery, voiding dysfunctions are often exaggerated. Cyclobenzaprine (Flexeril®) in conjunction with NSAIDs has long been the basis for management of acute musculoskeletal injuries, but the practice of prescribing this centrally acting muscle relaxant for post-operative patients has also been successful in the management of pain. An online search of medical databases revealed that there are currently no published retrospective or prospective studies determining the efficacy of cyclobenzaprine in post surgical patients in conjunction with traditional pain management. The investigators hypothesize among healthy patients undergoing elective vaginal surgery for pelvic organ prolapse, the short-term use of a muscle relaxant could reduce the spasticity of the pelvic floor muscle attributable to surgery and thereby reduce the use of narcotics. Consequently, the reduction of narcotics and the control of post-surgical pain may also hasten the return of normal urinary and defecatory function.

The purpose of this study is to determine whether a continuous infusion of local anesthesia with a catheter in the surgical wound reduces patient consumption of opiates by 30% in the 48-hour postoperative period following surgery for colorectal neoplasm and hepatic surgery versus the continuous infusion of physiological serum.

The investigators hypothesize that pregabalin will decrease post-operative pain scores and analgesic use following total mastectomy compared to placebo. The primary outcome will be acute postoperative pain, measured by a verbal numerical rating score (VNRS) and total analgesic consumption during postoperative 48 hours. The secondary outcome will be VNRS at 1 week and 1 month after operation.

Hemorrhoidectomy can be carried out under several modes of anesthesia. In western country hemorrhoidectomy usually be performed under general anesthesia, however there may be the complications resulted from general anesthesia together with associated diseases in advanced age, caudal or spinal anesthesia has been used as an alternative to general anesthesia (GA) for hemorrhoid surgery but they all require a trained anesthetist and have numerous known complications. Since, anesthesiologists are not always available then local anesthesia is an alternative mode of anesthesia that surgeon can safely carry out by their own. Local anesthetic produce a loss of sensation and muscle paralysis in a circumscribed area of body by localized effect on peripheral nerve endings. The local anesthesia is able to provide fully relaxation of the anal canal which is an ideal setting for various anal surgical procedures. The results of hemorrhoid surgery under this mode of anesthesia have been demonstrated in many publications. Local anesthesia is a safe and effective technique while fewer risks and complications compared with general or spinal anesthesia. In Thailand both spinal anesthesia and local perianal block have routinely been used for various kinds of anorectal surgery. However, so far there has no any trial conducting to compare between these two techniques.

Effective treatment of pain after hip fractures is very important but difficult. It is often an old patient who has many adverse effects with the use of morphine. This is a randomized pilot study where the investigators want to compare Norspan plaster to Oxycontin tablets to patients with particular kind of hip fractures. The investigators will evaluate mobilization, pain, use of rescue medicine, adverse effects and length of stay. No clinical study about the effect of Norspan as acute painkiller has never been done before. Can the investigators get the patients mobilized earlier with less adverse effects?

The investigators hypothesize that patient controlled analgesia (PCA) provides superior pain relief and patient satisfaction when compared to scheduled intravenous analgesia following vaginal reconstructive surgery.
