intravenous infusion

^[1]^[2]^[3]

Introduction

Introduction of fluid other than blood into a vein, i.e. an intravenous infusion.

bolus of intravenous fluid for dehydration or hypovolemia = 1 liter bolus in patients without heart failure of renal failure
- for elderly or patients with heart failure of renal failure, bolus of 500 mL
infusion of 60 mL/hr = 1.44 liters/day; 75 mL/hr = 1.8 liters/day
restricting the use of chloride-rich intravenous fluids in critical illness reduces acute kidney injury & the need for renal-replacement therapy^[2]
substitutes for normal saline include
- Hartmann solution
- Plasma-Lyte 148
20% Albumex
