Filter by:The primary objective of this study is to evaluate the pharmacokinetic profile of a single dose of intravenous ibuprofen administered over approximately ten (10) minutes.
The main purpose of this study is to examine if pain levels treated with intrathecal (IT) preservative-free morphine (PFM) after a cesarean section improve with the additional use of continuous subfascial wound infiltration with ropivacaine using the OnQ® elastomeric pump system.
To date, very little is known about the mechanisms of open-label placebo treatment and there is a lack in highly controlled experimental designs. Therefore, the planned project will test well-established explanatory models of (deceptive) placebo, i.e., (1) expectancy, (2) meaning response, in an open-label placebo design, investigating their influence on placebo analgesia.
In the proposed study, investigators aim to investigate the role of interpersonal trust in the conditioned placebo analgesia process with healthy male subjects in a standardized experimental heat pain paradigm.
Chronic painful knee OA is a major cause of disability in older adults. In patients whose symptoms are refractory to conservative management but who do not wish to undergo TKA or, alternatively, are not operative candidates, genicular nerve RFA represents a promising treatment option. Investigators will determine if patients with chronic painful knee osteoarthritis experience meaningful and long-term improvement in pain, function, and analgesic use, as well as prevention of TKA after RFA of the genicular nerves. Investigators will also determine whether zero versus one set of diagnostic genicular nerve blocks Answering these questions will help determine if genicular nerve RFA is indeed a worthwhile treatment for chronic painful knee OA. Additionally, this will help determine the optimal diagnostic protocol for patient selection for this procedure, which has implications for improving treatment success rates, preventing unnecessary procedures, and decreasing healthcare cost savings.
This is a single center, double blind, randomized, parallel-group study to assess the effect of 200mg caffeine,400mg caffeine and decaffeinated on acupuncture analgesia with the human pain model.
Patients undergoing thyroidectomy are suffering not only surgical wound pain but posterior neck pain because of neck extension position during the surgery. However, there has been little attention of posterior neck pain. Nefopam and Propacetamol have different pharmacodynamics and been used for postoperative pain control in thyroidectomy patients. The aim of this study is evaluation of combination effect of Nefopam and Propacetamol for acute wound pain, posterior neck pain and chronic pain after thyroidectomy.
In regional anesthesia local anaesthetics alone provide analgesia for not more than 4-8 hours. Increasing the duration of local anaesthetic action is often desirable because it prolongs surgical anaesthesia and analgesia. Different additives have been used to prolong regional blockade. Vasoconstrictors can be used to constrict vessels, thereby reducing vascular absorption of the local anaesthetic. Additives like opioids, clonidine and verapamil were added to local anaesthetics, but the results are either inconclusive or associated with side effects. Steroids when used intrathecally are reported to cause arachnoiditis, but there is no evidence suggesting any neuritis when steroids are used in low concentration in peripheral nerve blocks. Steroids have powerful anti-inflammatory as well as analgesic properties. Perineural injection of steroids is reported to influence postoperative analgesia. They relieve pain by reducing inflammation, and blocking transmission of nociceptive C-fibres and by suppressing ectopic neural discharge. The addition of 5 mg of dexamethasone to 10 ml of 0.5% levobupivacaine in interscalene brachial plexus block showed improvement of postoperative analgesia for arthroscopic shoulder operation without any specific complications. The objective of this study is to compare the effects of combining of dexamethasone and bupivacaine versus bupivacaine alone in combined femoral and sciatic nerve block in patients undergoing lower limb vascular surgeries. The effects will be studied in terms of: - Onset of sensory blockade and motor blockade - Duration of analgesia / first request for analgesic - Duration of motor blockade
The aim of this prospective randomized study was to evaluate the impact of peroperative pupillometry monitoring on per and post-operative opioid consumption in major gynecological surgery. All patients were anesthetized with TCI of propofol and remifentanil. In the intervention group, peroperative remifentanil target was guided by pupillometry. In the other group, remifentanil was administered according to standard practice.
The purpose of this randomized study is to examine the effect of a selective suprascapular nerve block on post operative pain after arthroscopic shoulder surgery. Half of the subjects will receive a active nerve block with Ropivacain. Half of the subjects will receive a placebo nerve block with saline.
