Abstract

Introduction

  • In the 1940’s, exchange transfusion (ExT) was introduced to help decrease the morbidity and mortality associated with haemolytic disease of the newborn (HDN) and prevent kernicterus.

  • ExT was subsequently applied to other causes of neonatal hyperbiliribinaemia, severe neonatal anaemia from a variety of causes, some non-immune hydrops cases, Neonatal metabolic conditions such as hyperammonaemia, severe hyperkalaemia and neonatal haemochromatosis.

  • In the 1970’s when ExT was exclusively used for the management of HDN, Lucey et al, predicted a decrease in frequency of this procedure for HDN in future.

  • Complications were estimated to increase due to the lack or decreased frequency of ExT with time.

Objectives To determine.

  • Number of ET done over a 6 yr period.

  • Patients demographics, time of ExT, Indications.

  • Number of Babies who have had Inutero ExT.

  • Maternal details: Blood group, antibodies.

  • The level of bilirubin at which transfusion took place.

  • Prior treatment pre-ExT: In-utero Tx, Intravenous Immunoglobulin (IVIG) use; use of albumin infusion.

  • The ExT-related complications: Any complication not present prior to the ET which occurred within 48 hrs after the ET: Defined as follows- platelet count <150, hypocalaemia, ionised Calcium <0.8, fits, raised INR.

Methods

  • Setting: Level 3 NICU.

  • Retrospective notes review of patients who underwent ExT.

  • January 2008–March 2014 (6.25 yrs).

  • Exclusion criteria: Those for which notes were not obtained.

Results

  • Total admissions to the NICU over the period = 5,000.

  • Number of exchange transfusions done= 15 in 14 patients.

  • 0.3% of admissions over the period.

  • Table of cases.

Abstract PO-0326 Table 1
  • Total number of request made to the Blood transfusion department for blood product for exchange.

Conclusion

  • Average ExT/yr in a Level 3 NICU = 2.4/yr.

  • ExT is currently being used for a variety of causes.

  • There were no complications related to the procedure itself.

  • Complications post-ExT were all biochemical (hypocalcaemia- in 13 cases) or haematologic (low platelets 13 cases)

  • Use of IVIG: Given pre-Ext to all ABO, Rh cases except 2 and to the Non-immune hydrops secondary to Parvovirus.

  • 1st documented case of ExT use in hyperbilirubinaemia secondary to accidental Hyperlipidaemia from TPN-Lipid infusion and Haemolysis with Anaemia post-Octenisan wash treatment for MRSA-colonisation treatment in a preterm baby.
