- 1 - 2 minutes
- 3 minutes
Hypotension: systolic <70 mmHg, NOT due to hypovolemia.
Hypotension due to hypovolemia
- Fluid replacement should be initiated first.
- Use caution if Pt is on beta blockers.
- Give through largest vein readily available as tissue necrosis can occur if medication extravasates.
- Increases myocardial oxygen demand: use with caution in Pt with myocardial ischemia.
- Can be deactivated with alkaline solutions such as Sodium Bicarbinate.
- Constant monitoring of BP is essential.
- Nausea / Vomiting
- Improves renal blood flow and urinary output in septic Pts.
- Dilute: 8 mg in 500 mL D5W (16 mcg/mL)
- 4 mg in 250 mL D5W (16 mcg/mL)
- 0.1 - 0.5 mcg/min per AHA, however higher doses may be required to maintain adequate BP.
- Should be piggybacked into an existing IV infusion & administered via a controlled pump.
- 0.01 - 0.5 mcg/kg/min
