Filter by:Chronic arthritis (inflammation of joints) in children is known as Juvenile Idiopathic Arthritis (JIA). Often, to control the swelling and to help reduce the pain in the joint, medications (steroids) are injected into the joint. These injections are sometimes painful, even if we use local anesthetics (lidocaine) to numb the skin; in fact, lidocaine injection is often the most painful part of the procedure. There is an alternate method called iontophoresis that uses an electric current to push lidocaine into the skin and deeper tissues avoiding the anesthetic injection. Very little work has been done to see if this is actually an effective way of numbing the skin in children having painful procedures such as joint injections. In this study, we will compare two groups of children with JIA having steroid injections into their joints: one group will get lidocaine by iontophoresis and the other will get it by the usual injection method. We will assess the child's pain during the steroid injection and compare the two groups to see if children who are given local anesthetic by iontophoresis experience less pain. The results of this study will provide new information about the effectiveness of the iontophoresis method, and whether or not this would be a better way to give local anesthetic for children undergoing other kinds of painful procedures.
Our study is about providing a better birthing experience by placing and initiating epidural for labour pain before the contractions start. This concept of prevention of pain before its onset is known as preventive - or preemptive -pain management and is well known in surgical and anaesthetic practice. We believe that the use of preventive epidural analgesia will improve the quality of labour epidurals, increase maternal satisfaction and reduce the stress response to labour and delivery.
Double-balloon enteroscopy (DBE) is a novel endoscopic procedure for visualising the entire small bowel. In any GI endoscopy procedure it is mandatory to insufflate gas into the bowel to secure good visualisation. All endoscopes used for GI endoscopy provide a gas insufflation unit. Currently, air is used for this purpose in more than 90% of centres throughout the world. The use of air, however, is far from ideal to use for insufflation in GI endoscopy. After GI endoscopy, significant amounts of air are usually retained in the bowel segment inspected (5). This air has to pass the GI tract and exit physiologically through the rectum. Thus, abdominal pain and discomfort during and after the examination due to the retention of air has been shown to be very common during and after endoscopic procedures (5-9). Carbon dioxide gas (CO2), unlike air, is rapidly absorbed from the bowel. Within minutes, several litres of CO2 can be absorbed from the GI tract. The use of CO2 has been shown to result in more comfortable examinations in both colonoscopy and flexible sigmoidoscopy in several randomised trials (6-9). In these studies, CO2 insufflation almost completely reduced procedure-related pain and discomfort. To our knowledge, no research has been performed investigating the use of CO2 in DBE. DBE is a long-lasting procedure (mean examination time 75 minutes (4)). Large volumes of air are insufflated during the procedure, leading to significant distension of the small bowel during and after the examination. One of the main technical difficulties in DBE is the formation of small bowel loops and scarp angels during deep intubation of the endoscope. These loops and angels are the major restriction to deep intubation of the endoscope. Loops and scarp angels are more pronounced in air-distended bowel segments. The aim of the present study is to examine whether CO2 insufflation leads to a reduction of abdominal pain in DBE patients. Furthermore, we want to investigate if CO2 insufflation facilities a deeper intubation of the endoscope and thus a more complete examination of the small bowel mucosa. The study is designed as a two-centre randomised controlled trial. Randomisation to the two treatment groups (CO2 or air insufflation) is performed on basis of the individual participant.
Chronic, unexplained pain symptoms are very common in all layers of the population, but it is largely unknown what causes them. This study examines the hypothesis that patients with these pain symptoms process pain abnormally in their brain. TO this aim, we compare patients and healthy people: they receive mild pain at their painful body region and at another location. Concurrently, we measure brain activity with brain scans (functional MRI scans). With our study results, we want to increase understanding of what causes chronic, unexplained pain symptoms, in order to find better methods of diagnosing and treating them.
Oncology patients require numerous invasive procedures throughout their disease process including bone marrow biopsies (BMB). BMB.s are performed by a significant number of health care providers. One of the biggest concerns for health care providers is to improve patient comfort. The goal of this study was to reduce pain during BMBs. Specific aims of the study were to determine if there is a difference in patients' perceived pain during injection of the pre-procedure anesthetic when buffered versus unbuffered lidocaine is administered to patient's receiving bone marrow biopsies. A double blind, experimental crossover design was used to examine the difference in pain levels when using buffered versus unbuffered lidocaine prior to the bilateral bone marrow biopsy procedure. Based on a power analysis for a paired t-test, a convenience sample of 48 patients was enrolled into the study. Patients served as their own control. The site of first biopsy, and which lidocaine solution was administered first, were randomized. A 100mm visual analogue scale (VAS) was used to measure pain. All data has been collected, are currently under analysis, and results will be completed in August 2006. Differences in groups will be examined using a paired t-test. A demographic questionnaire was used to gather select demographic variables. Correlative studies will be done to examine the relationship between the patient's perceived pain scores and several exploratory variables. Results of this study may change the current type of anesthetic used pre-BMBs thus improving patient comfort.
This study was undertaken to compare the two techniques (exteriorized vs in situ) of uterine repair with respect to patient comfort, hemodynamic changes, surgical time and blood loss, in patients undergoing elective CD under a strictly standardized spinal anesthetic. We hypothesized that in situ uterine repair would be more comfortable for the patients.
The purpose of the study is to determine the effect of Egalet® Morphine once daily compared to MST Continus twice daily on pain intensity and use of rescue medication for break through pain after 2 weeks of treatment in patients with pain due to cancer.
This phase IIa (proof of concept) study will be conducted as a multi-centre study within the European Union (EU). It will be conducted to a randomised, single blind, placebo- controlled, parallel group design with a positive control arm to evaluate the analgesic efficacy of pre-emptive doses of GW842166 following dental surgery (3rd molar tooth extraction). GW842166 will be administered as a single pre-operative oral dose in male and female subjects who will be randomised to take part in one of four possible treatment regimens. Pain assessments will be undertaken over a 10 hr period. Pharmacokinetic blood samples will be collected over a 48 hr period. Safety and tolerability will be evaluated by adverse event monitoring, cardiovascular assessments (ECG and vital signs) and clinical laboratory tests (haematology, clinical chemistry and urinalysis).
This trial is a comparison of the anesthetic effectiveness of J-Tip needle-free jet injection of 1% buffered lidocaine to the anesthetic effectiveness of topical 4% ELA-Max for peripheral intravenous catheter (PIV) insertion. The researchers hypothesize that the jet injection of lidocaine will provide superior anesthesia to the ELA-Max prior to PIV insertion.
