#98 – A Deep Dive on Ketorolac with Elisabeth Stewart, MSN, MSNA, CRNA

Elisabeth Stewart, MSN, MSNA, CRNA focused her Master of Science in Nurse Anesthesia project on the pharmacology of Toradol (ketorolac) and she’s here today to tell us all about it.

Elisabeth hails from Wisconsin, holds a BS in Mathematics with a pre-med concentration and engaged in HeLa cell cancer research prior to going to nursing school.  She received a Master of Science in Nursing degree at the University of Wisconsin – Milwaukee, where she worked in a transplant ICU while completing her Clinical Nurse Leader degree and certification.  Elisabeth followed that with her Master of Nurse Anesthesia degree at the University of New England and received the UNE Outstanding Student Award for her class. Her primary clinical site in training was Maine Medical Center in Portland, Maine. When Elisabeth showed up for day one of clinical, I was serving as the SRNA Clinical Coordinator and by the time she was completing her training, I was a year into my new role as Chief CRNA at Maine Medical Center. Elisabeth was one of the best SRNAs we’ve had roll through Maine Med in years and brought a degree of professionalism, conscientiousness and excellence in clinical care that inspired confidence in her practice and reallllly made me try to recruit her as a clinical staff. As it is, she’s chosen to start her career closer to family in Massachusetts and I wish her the absolute best moving forward.

I think you’re really going to enjoy hearing Elisabeth walk through the pharmacokinetics and pharmacodynamics of ketorolac with specific focus on the risk (or lack thereof) of bleeding with the use of ketorolac. Elisabeth focused primarily on the risk of bleeding in adult breast surgery patients. She reviewed 27 research articles to boil down what the literature says about the role of ketorolac in perioperative bleeding risk in breast surgery patients. Her full write up is attached in the show notes to this episode. And with that, let’s get to the show!
