14.05 Dopamine (Inotropin)
used to improve blood pressure, cardiac output, and urine output
Smaller doses result in renal vasodilation
Doses 2-10mcg/kg/min result in cardiac stimulation by acting on beta1 receptors
Doses >10mcg/kg/min stimulate alpha receptors leading to vasoconstriction (↑SVR)
• Monitor hemodynamics closely: BP, HR, EKG, CVP, and PAOP if available
• Obtain parameters for hemodynamic values
• Titrate to obtain appropriate BP (more potent vasoconstrictors may be required)
• Irritation may occur at IV site
• Beta blockers may counteract therapeutic effects
Cornell Note-Taking System Instructions:
- Record: During the lecture, use the note-taking column to record the lecture using telegraphic sentences.
- Questions: As soon after class as possible, formulate questions based onthe notes in the right-hand column. Writing questions helps to clarifymeanings, reveal relationships, establish continuity, and strengthenmemory. Also, the writing of questions sets up a perfect stage for exam-studying later.
- Recite: Cover the note-taking column with a sheet of paper. Then, looking at the questions or cue-words in the question and cue column only, say aloud, in your own words, the answers to the questions, facts, or ideas indicated by the cue-words.
- Reflect: Reflect on the material by asking yourself questions, for example: “What’s the significance of these facts? What principle are they based on? How can I apply them? How do they fit in with what I already know? What’s beyond them?
- Review: Spend at least ten minutes every week reviewing all your previous notes. If you do, you’ll retain a great deal for current use, as well as, for the exam.
