Managing Intra Op Hypotension with Amanda Shelby

We are all taught in school that if a patient become hypotensive, they should receive a fluid bolus. But, does that make sense for all patients? When do you reach for an anticholinergic? When do you start that dopamine or norepi? Amanda Shelby RVT, VTS (Anesthesia & Analgesia) is here to explain it all to us. Resources mentioned in this episode: 1. Harro C, Foster JD.
