Filter by:A double blinded randomized controlled trial comparing the onset and duration of the Onset and Duration of Ultrasound Guided Supraclavicular Nerve Blocks Using a long acting local anesthestic (Ropivacaine) with a mixture of a long and short acting local anesthestic (Ropivacaine-Chloroprocaine Mixture).
Pain is one of the most common symptoms associated with cancer. The approach to pain management compresses routine pain assessments, utilizes both pharmacologic and nonpharmacologic interventions, and requires ongoing reevaluation of the patient. Cancer pain can be well controlled in the vast majority of patients if the algorithms of pain control are systematically applied, carefully monitored, and tailored to the needs of the individual patient.This study is aimed to assess the current pain managements in upper gastrointestinal cancer patients in Taiwan. The effects of neuropathic pain and depression on the enrolled patients would also be assessed.
The purpose of the study is to learn about the causes of different types of pain that can occur in people who have had an amputation. By gathering information through blood tests, photographs, a nerve test, and questionnaires, we hope to de-code how each individual's special characteristics affect the type and amount of pain they experience in their amputated limb.
Compared with standardized western medical drug therapy, this study is mainly about whether the combination of standardized western medical drug therapy and Chinese medical continued treatment, can further decrease the rate of cardiovascular events for stable angina patients and change the condition of angina.
To determine the efficacy and safety of vapocoolant spray (Pain Ease Medium Stream) in decreasing the pain of venipuncture ("blood draw")
The purpose of this study is to assess the efficacy of intranasally-administrated fentanyl spray to decrease the pain during cystoscopy (the passage of a telescopic instrument into the bladder for purpose of diagnosing the cause of blood in the urine, urinary complaints or any other problems with the urinary bladder). The current standard practice is to use Lidocaine jelly (a local anesthetic) given through the urethra to lubricate and decrease pain. In this study, an additional medicine (fentanyl) is used to reduce pain that occurs during and after the above procedure.
This is a prospective, randomised, double-blind, placebo-controlled, parallel group study in approximately 75 patients undergoing surgical removal of an impacted lower third molar.
Total knee arthroplasty (TKA) is a worldwide realized procedure, with 600.000 surgeries performed per year in the United States, with a 673% increase estimated until 2030. Functional and pain management improvement is expected in 90% of patients, with 85% of them satisfied after the procedure. Immediate postoperatory pain control is an important aspect to be considered. Patients submitted to TKA endure pain with variations between 40-80 (according to analog visual scale -AVS - which goes from zero to 100) during the immediate postoperatory, with slow decline in the first 24 hours. Pain classified as severe occurs in 60% and moderated in 30% of patients submitted to TKA during this period of time. Therefore adequate pain management allows an earlier rehabilitation, with a higher satisfaction rate and decrease the hospitalization period. A multimodal control of pain can be reached by using non-steroidal anti-inflammatory, COX-2 anti-inflammatory inhibitors, peripheral nerve blocks and intra-articular anesthetics injections and decrease use of opioids given of potential collateral effects. Peripheral blockings are associated to the smallest rate of collateral effects and complications when compared to the spinal anesthesia and analgesia controlled by the patients. Studies comparing the effects of the femoral and sciatic-femoral blocking guided by ultrasonography for the analgesia control after TKA were not found. The objective of this article is to evaluate the effect of femoral and sciatic-femoral block using ultrasonography by the analog visual scale (AVS) of pain in postoperatory of patients submitted to TKA, opioid consumption and complications associated to anesthesics procedures.
No one knows how long bupivacaine finger blocks last. Many use bupivacaine with and without epinephrine, but no one knows how the epinephrine affects the duration of the block. We also don't know how long the pain part of the block lasts, which is what counts. The goal of the study is to determine the duration of action of bupivacaine digital nerve blocks (with and without epinephrine) on finger temperature and the sensory modalities of pain, touch, and pressure. 2 ml of bupivacaine 0.5% with and without epinephrine will be injected at the base of each ring finger on the palm surface. At the end of 1 hr, 6 hrs, 12 hrs, 14 hrs and each additional hour, patients will use an insulin lancet to measure pain, the Semmes Weinstein monofilament test to measure light touch and pressure and a body surface thermometer to measure finger temperature. The time for the finger to return to normal sensation and temperature will be measured.
Objective: Epidural analgesia is the gold standard for post-thoracotomy pain relief but is contraindicated in certain patients. An alternative is continuous wound catheter analgesia. We will investigate whether ropivacaine, administered through a wound catheter placed by the surgeon, will reduce postoperative pain. Methods: In a randomized double-blind study, adult patients with a wound catheter placed by the thoracic surgeon after thoracotomy will be randomly assigned to receive through this catheter, either a 0.1 mL/kg bolus of 0.75% ropivacaine, followed by a continuous infusion of 0.2% ropivacaine at 10 mL/h for 48 h, or saline at the same scheme of administration. Patients will also benefit from patient-controlled analgesia with intravenous morphine (bolus 1 mg, lockout time 7 min), paracetamol, and nefopam. The primary endpoint will be total morphine consumption. Secondary endpoints will be pain intensity on a visual analog scale at rest and on coughing and side effects during the first 48 postoperative hours. Surgeons, anesthesiologists, and all the nurses and caring staff involved in this study will be blinded. Solutions of saline and ropivacaine will be prepared identically by the central pharmacy, without any possible identification of the product.
