Well, I graduated 1974.
That would be a book, to catch all the differences. Let's try just a few.
1. Nurses BEHIND the doctor. NO questions. Doctor said: "20 mg of Morphine" - answer "Yes, Sir"
2. No disposable stuff whatsoever. Daily sterilization of syringes (glass) and needles (steel). Cleaning inside needles.
3. Bedpans, urinals - metal.
4. No IV pumps, I remember first IV pumps (very primitive by today's standards) used for pressors only.
5. 3 color charting - depends on the shift: morning - blue, afternoon - green, night - red.
6. Monitors on ICU, sometimes one monitor for a patient, no central monitor (however, sometimes happened a central, alarms printed with hyphens r/t number of the bed [bed nr 3 = ---], no differentiation for alarms, like the same sound for disconnected electrode or VF).
7. Smoking - patients, nurses, doctors - one exemption was OR, however in the OR lounge everybody smoked.
8. Very HOT OR - at least 98-99 degrees, no patient's warming blankets.
9. Only one nurse dispensing meds for the whole unit (except ICU).
10. Three 8 hrs shifts.
11. Gloves ONLY for the OR, specifically the surgical team.
12. Continuous staff cover for OR (no calls).
13. Making gauze dressings (today's 4x4's or 2x2's).
14. Celebrating coffee meeting for the whole team after each medium/big surgery (maybe except for little cases like T&A).
15 Long turn on surgical cases (see # 14).
16. In each and every hospital each unit had a physician present 24/7 (not on call), on occasion a physician present on unit called himself for help (e.g. emergency big surgery).
and so on, and so on...
