Clinical trials

Dr. Parker Merrill (anesthesiologist) and Dr. Chris Neal (neurosurgeon) are working on a research study comparing two methods of pain control for patients having spinal fusion surgery. We are looking for English-speaking patients between 18 and 70 years old who are scheduled for 1-2 level lumbar spine fusion surgery. Participants in this study will either get morphine injected during surgery (current pain treatment) or morphine and another drug, clonidine. There is an equal chance of getting the two treatment options. No matter which group you are assigned to, you will be provided with additional pain medication if needed after your surgery. You may not directly benefit from participating in this study, but you might have an improvement in your pain after surgery. You will also be helping researchers and doctors find better pain control options for future patients.

This is a prospective, observational study to investigate molecular mechanisms mediating the systemic inflammatory process, and changes to metabolism, and their impact on brain injury, survival, and functional outcomes after cardiac arrest. Investigators have shown that cardiac arrest induces changes in the numbers and properties of circulating immune cells, shifting the balance towards a pro-inflammatory phenotype and there is increased interest in the inflammatory pathways and the signaling mechanisms through which they are modulated. Participants will undergo blood sampling during 7 days following cardiac arrest, and analyses performed. Patient characteristics, clinical circumstances, and outcomes will be recorded and their associations with these inflammatory pathways characterized.
