Hemodynamic Response to Fluid Boluses for Hypotension in Children in a Cardiac ICU

Abstract

Objectives: To describe the hemodynamic response to fluid boluses for hypotension in children in a cardiac ICU. Design: A prospective, observational study. Setting: Single-centered cardiac ICU. Patients: Children in a cardiac ICU with hypotension. Interventions: Clinician prescribed fluid bolus. Measurements and Main Results: Sixty-four fluid boluses were administered to 52 children. Fluid composition was 4% albumin in 36/64 (56%), 0.9% saline in 18/64 (28%), and cardiopulmonary bypass pump blood in 10/64 (16%). The median volume and duration were 5.0 mL/kg (interquartile range, 4.8-5.4) and 8 minutes (interquartile range, 4-19), respectively. Hypovolemia/low filling pressures was the most c..
