Filter by:Currently, there are no studies that address the optimum dosage of lidocaine for surgical procedures. Lidocaine is a local anesthetic that is injected to induce anesthesia. Improper or inefficient pain treatment can lead to longer hospital stay, and adverse side effects such as nausea and vomiting. Opioids are the primary drug to treat moderate to severe pain, but are also responsible for nausea and other side effects. Lidocaine has shown to have opioid sparing effects; meaning less opioid use is necessary for pain relief. In this study, we will conduct a clinical trial to assess the difference between different lidocaine dosage schedules to determine the optimum dosage that brings maximum pain relief while minimizing adverse side effects and patient stay. A large benefit in using lidocaine is its documented opioid sparing which allows for minimal drug treatment.
Bariatric surgery is the most effective, long-term treatment for morbid obesity, and consistent with previous findings, individuals who lose significant weight after surgery also have improved cognition or "brain function". The mechanisms behind these cognitive improvements are currently unknown, but are the focus of much research effort. The goal of this pilot study is to thoroughly describe these changes in surgical versus medical weight loss patients over time in a repeated measures fashion.
An anaesthetist inserts a "laryngoscope" into the mouth to see the voice-box (larynx) for "tracheal intubation", when a tube is advanced into the windpipe (trachea) to protect the airway and administer anaesthetic gases. This study aims to compare traditional (direct view) Macintosh (MAC) laryngoscopy with Storz C-MAC videolaryngoscopes in subjects presenting for obesity reduction surgery using a novel "photographic overlay technique" to analyse the basis for any differences.
This study will attempt to determine whether having gastric bypass surgery changes the way that the gut absorbs hormones from birth control pills. It is believed that, because gastric bypass surgery causes malabsorption of nutrients and some medications, the levels of birth control hormones after the surgery will be lower than in women before they have the surgery. The investigators will ask several women to take a pack of birth control pills before having bypass surgery, and then another pack several months after surgery. The investigators will measure hormone levels in the blood. The investigators will also measure outcomes that may tell us how well the birth control pills are working, such as ultrasounds of the uterus and ovaries, and examination of the cervix.
