Welcome to Regional Anesthesia Research at Providence Health Care!
Our growing regional anesthesia research program takes advantage of our close association with the UBC Department of Anesthesiology, Pharmacology & Therapeutics and the UBC Hugill Anesthesia Research Centre on Point Grey Campus. Guided by our philosophy to pursue a curiosity-driven, collaborative, interdisciplinary, and translational approach, our work spans the spectrum from clinical human investigation to fundamental pharmacological in vivo laboratory studies and in vitro neurophysiological experimentation.
Our research team includes staff MD anesthesiologists, PhD scientists, anesthesiology residents, fellows, medical students, pharmacology graduate students, and undergraduate students. We work together to improve for our patients long- and short-term perioperative outcomes, reduce surgical wait lists, and enhance efficient resource utilization through designing innovative regional anesthesia-based care models, identifying evidence-based state-of-the-art therapies, developing novel long-lasting and safe pharmacological agents, and discovering new knowledge on the cellular and molecular basis of local anesthetic and analgesic drug action. Our vision is to effectively and safely eradicate acute and chronic pain after surgery.
The program provides research training opportunities for clinical fellows as an integral component of our regional anesthesia fellowship program, as well as pharmacology graduate students through UBC.
Our work has been featured in the print press as well as on television. Funding sources for the laboratory research have included the Canada Foundation for Innovation, the Canadian Anesthesia Research Foundation, and the Hugill Anesthesia Research Endowment. Many of our research initiatives continue to rely on personal initiatives and support from scarce departmental resources; we welcome philanthropic donations and support for the sustenance and development of our programs, which directly benefit British Columbians undergoing surgery.
