Filter by:Ketamine (an analgesic drug often associated with morphine in the treatment of Opioid Induced Hyperalgesia) is often mixed in Morphine PCA syringe. We make the hypothesis that ketamine administrated separately via a continuous infusion, could induced a better analgesic effect. We will perform a randomised double blind study to determine the best infusion mode of intravenous ketamine, associated with morphine in PCA syringe or alone in continuous infusion.
Skin preparation solutions are used to clean the skin of the patient before surgery to decrease the rate of infection. This is particularly important for hip replacement to reduce the risk of prosthetic joint infection. The use of a mark on the skin for site identification has become the standard of care to decrease wrong site surgery. The Joint Commission has mandated site identification as part of the surgical "time-out". This procedure is also mandated by hospital policy. Preliminary work on cadaveric skin shows that the type of skin preparation can erase the mark used for surgical site identification. Erasure of the mark presents the surgeon with difficulty in performing the site identification. Any error or lack of visualization of the site marking could lead to catastrophic wrong site surgery. The investigators hypothesis is that chlorhexidine based skin preparation solutions erase site marking in comparison to iodine based skin preparation solutions. The investigators intend to prospectively study twenty patients undergoing total hip arthroplasty. Patients will be randomized to either a chlorhexidine based or an iodine based skin preparation solution. These solutions are both the current gold standard of clinical care. No differences have been shown in infection rates for total hip arthroplasty between these solutions. The site marking will be performed by the same surgeon in a standardized manner. The site marking will include the surgeon's three initials as per usual routine. Underneath the initials three random initials will be placed with a horizontal line drawn underneath. The preparation of the skin will be performed according to the manufacturer's specifications. Digital photographs will be taken of the skin marking after skin preparation. Photographs of the three random initials will be de-identified and placed in a "Powerpoint" presentation form. Ten orthopaedic surgeons will then read the site markings to identify the random initials and to tell whether the mark looks appropriate to perform a surgical timeout. The horizontal line will be digitally analyzed using Adobe Photoshop to quantitatively measure blackness of the mark.
The purpose of this study is to evaluate a hip implant system used when a previous hip replacement surgery has failed.
Total hip replacement surgery is considered to be a very successful surgical procedure for the treatment of degenerative joint disease. The purpose of the study is to evaluate a large size (36mm, 40mm or 44mm) femoral (hip) head called the LFIT™ Anatomic CoCr Femoral Head (Low Friction Ion Treatment). The large size femoral heads will be used with the Trident® X3® polyethylene (plastic) inserts and will be compared with a historical control. Study Hypothesis: The linear wear rate for hips implanted with the LFIT™ Anatomic CoCr Femoral Head is no worse than 0.08 mm wear per year at 5 years post-surgery.
We will compare the effectiveness of Quixil and Tranexamic acid in reducing bleeding during hip and knee joint replacements.
This study is performed to confirm the optimal dose for THR (total hip replacement).
A study to determine the effectiveness and safety of the use of metal-on-metal hip resurfacing (for example the birmingham hip) when compared to conventional total hip replacement.
The purpose of this study is to determine whether wound infiltration with following single-shot bolus injection with local anesthetic and NASIDs are effective in the treatment of postoperative pain after total hip replacement compared to continuous epidural infusion.
This is a VA Merit Review Study involving 7 VA medical centers participating in a parallel group randomized trial comparing "repeat back" versus standard electronic consent for 4 common elective surgical procedures (total hip arthroplasty, carotid endarterectomy, laparoscopic cholecystectomy, and radical prostatectomy). Baseline covariates include health status (SF-12), reading ability (REALM), and demographics. Primary outcomes are patient comprehension of the informed consent, patient satisfaction with the informed consent and decision making processes, patient satisfaction with care, anxiety (STAI), and provider assessment of the "repeat back" process. In addition, we are electronically capturing data detailing time spent in each phase of the consent process including "repeat back".
The study aims to determine if a New Arthroplasty Care Model, established on evidence-based medicine and best practices, will improve patient outcomes and improve cost effectiveness for patients with severe degenerative joint disease of the hip or knee in Alberta
