Intravenous fluids are administered to children for 4 main reasons: Maintenance Electrolyte imbalance Circulatory support On-going replacement losses 0.18% Sodium Chloride + 4% Glucose became the fluid of choice following the findings of Holliday and Segar in child deaths and 1 near miss lead to concerns regarding use The NPSA published ‘Reducing the risk of hyponatraemia when administering intravenous fluids’ in 2007 Background

Does the NPSA alert influence practice? This study aimed to assess: Fluid types administered 0.18% Sodium chloride + 4% Glucose Extent of hyponatraemia Clinical guideline implementation Overview

Method Data collection Information we required from each trust: Are guidelines available? What fluids are used within the trust? Information we required for each patient: Basic demographics Age Weight Clinical background Reason for IV fluids Maintenance fluid administered Replacement fluids administered Duration of fluids Electrolyte monitoring Time and date of last recording Current sodium level Rate of fluid administration

Fluid administration Sodium Chloride 0.45% + 5% Glucose accounted for 91% of all hypotonic fluids No Patients received Sodium Chloride 0.18% + 4% Glucose 5 neonates received Sodium Chloride 0.18% + 10% Glucose Just over one third of all isotonic fluids were administered for fluid replacement purposes Results

Percentage maintenance volume of fluid Results

Hyponatraemia 30% of hyponatraemic cases were surgical patients o 57% of surgical patients received hypotonic fluids 45% received isotonic fluids Electrolyte monitoring was not completed for 22% of patients The majority (89%) of all trusts had clinical guidelines in place Other Results

Practice is changing following NPSA publication No patients received 0.18% sodium chloride + 4% glucose A large percentage of patients are still administered hypotonic fluids Isotonic fluids are used commonly as fluid replacement Most trusts have guidelines available (60% increase since 2004) More care is required in regards to electrolyte monitoring and volume of fluid administered Summary
