One of the most common issues I face are patients who have pain, anxiety, agitation, and delirium; sometimes all of them at once. Let's say we have a 75 year old female patient with a past medical history of dementia, chronic back pain with radiculopathy, CAD status post CABG, heart failure with a reduced EF, and ESRD on hemodialysis. She's on opiates, as well as on a neuropathic pain medication.  The patient was brought into the ICU for septic shock due to UTI. She required pressors and also has acute decompensated CHF and acute on chronic renal failure due to the infection. Today we are going to discuss the pharmacology of medications used for pain, anxiety, agitation, and delirium. We'll touch on: Fentanyl Dilaudid Morphine Propofol Dexmedetomidine Benzodiazepines Haloperidol Quetiapine - Subscribe to our YouTube here: http://www.youtube.com/subscription_center?add_user=medgeeks - Follow us on Instagram here: https://www.instagram.com/medgeeksinc - Ace your exams: https://learn.medgeeks.co - Have questions?
