Filter by:Pain is the most common complaint for patients presenting to the emergency department (ED). Inadequate pain relief is also a common problem in ED. Patients' pain perceptions and responses to intravenous opioids vary widely and are influenced by multiple factors. The objective of the current study is to examine the association between total body weight, BMI (body mass index) and clinical response to a fixed dose of intravenous hydromorphone.
To determine the efficacy and safety of vapocoolant stream (Pain Ease Medium Stream ) in decreasing the pain of intravenous cannulation. To compare vapocoolant stream (Pain Ease medium Stream) with control (e.g. sterile water) stream.
Pain after breast cancer surgery could be severe and about 1/3 of patients will develop chronic pain. The PECBLOCK is the injection of local anesthetics between the two pectoral muscles to block pectoral nerves and intercostal nerves innervating the breast. The aim of this study is to evaluate the efficacy of the PECBLOCK performed under echoguidance in minor and major breast surgery. The prevention of chronic pain following surgery will also be evaluated.
Surgery to correct scoliosis (spinal fusion)generates a severe pain intensity rending pain management a complex task. Several studies have found out that pharmacological interventions alone were not enough to provide optimal pain management for these patients. The investigators developed a DVD on guided imagery, customized for teenagers, to help them cope better with their pain. The investigators believe that this type of intervention combined with their usual analgesic medication will help them to control their pain and foster rehabilitation.
This randomised controlled trial aims to compare the effectiveness of hand reflexology received during office based vein surgery, under local anaesthetic on patient's reports of pain and anxiety, compared to usual standard care.
Pain during nuclear medicine breast lymphnode detection procedures has been reported as high as 8.8/10. Using Sodium Bicarbonate to alkalinize the radio-pharmaceutical injection, pain can safely be reduced from 6.6/10 to 4.7/10, during breast lymph node detection procedures. In sites other then the breast, using Bicarbonate to make the injection's pH closer to natural, attempts to lower the pain levels will be performed. Hypothesis: The perceived pain level during non breast sentinel lymph node techniques can be reduced by raising the pH of the injectate (Tc-99m SC) to near the physiologic level of pH 7.40.
The objective of this pilot study is to assess the efficacy of minimally invasive autologous fat transfers at the amputation sites and the modulation of pain at the respective sites. Our investigators hypothesize that autologous fat grafting can provide a minimally invasive therapy to effectively mitigate pain syndromes at amputation sites, by introducing volume stable subcutaneous tissue over bony prominences and peripheral nerve trunks, thereby avoiding major surgical revisions and preserving limb length. The investigators further hypothesize that enriching the fat graft with autologous adipose stromal cells, a regenerative medicine approach, will lead to improved retention of the fat graft over time and result in a more favorable outcome. The Investigators will evaluate: 1. Treatment of painful amputation sites in 5 patients with fat grafting, intended to provide additional subcutaneous tissue padding over bony structures and nerve trunks. Limb anatomy and healing of the graft over time, along with stability/persistence of the new tissue, will be assessed by high resolution CT scanning with 3D reconstruction. Patients will be followed for 24 months after treatment to define long term outcomes. Patients will be enrolled who have pain at an amputation site that limits function and/or interferes with the ability to use a prosthesis. 2. Biologic properties of the cells within the fat graft and correlate with clinical outcomes. This will include adipose stem cell yield per volume of fat tissue, cell proliferation, capacity for adipogenic differentiation, lipolysis, and cell sub-population analysis by multiparameter flow cytometry. Results of these assays will be correlated with graft volume retention to search for predictors of good clinical outcome that are related to variation on adipose biology between subjects. 3. Quality of life measurements in patients before and after autologous fat grafting using validated psychosocial measures. This will include SF 36, the Beck inventory, and instruments designed for assessing limb function.
Studies have shown that transcranial magnetic stimulation (TMS), a non-invasive form of brain stimulation, can reduce pain in the laboratory and in the clinic. The purpose of this study is to investigate how TMS relieves pain and affects pain circuitry in the brain. One of the primary study hypotheses is that opioid blockade will significantly reduce the pain relief produced by left prefrontal cortex TMS.
A Single Dose PK Study of OxyNorm® immediate-release capsules 5, 10, and 20mg, and a multiple-dose PK Study of OxyNorm® immediate-release capsules 10mg in Chinese patients with pain.It will be a single center, open label, randomized, oral administration study.
Pain is very common in persons with a history of addiction, but few studies have examined the best treatment of pain in this population. This is a study to determine the pain relief provided by intravenous hydromorphone (Dilaudid) or buprenorphine given to persons maintained on stable doses of methadone or buprenorphine. Experimental sessions will require overnight stays on a residential research unit. In these sessions, persons will be exposed to standard experimental pain techniques at baseline and then rate the relief (if any) provided by the study medication when exposed to the same techniques. Persons will be asked to participate in 2 or 3 sessions, each separated by at least 7 days.
