ECMO Alert

( Version 1.0 07/01/99 - 07/01/02)

Extracorporeal membrane oxygenation is the use of extracorporeal circulation and gas exchange to provide temporary life support in patients with reversible cardiac or pulmonary failure.

Indications: Infants with cardiac or pulmonary failure secondary to:

    • Congenital Diaphragmatic Hernia

    • Persistent Pulmonary Hypertension

    • Meconium aspiration

    • Sepsis

    • Hyaline Membrane Disease

Patient criteria:

    • Greater than 34 weeks gestation

    • Greater than 2000gm birthweight

    • Absence of terminal chromosomal anomalies

    • No non-correctable congenital heart disease confirmed by Echo

    • No intraventricular hemorrhage greater than grade I

    • Absence of profound asphyxia

    • Less than 7 days on a ventilator

    • Underlying disease capable of resolution in 10 days

    • Failure of maximal medical therapy

Infants who meet the above criteria and who have a PaO2 < 50 x 4 hours by arterial blood gas meet final criteria for being placed on ECMO.

If such an infant is deteriorating/not improving or is being transported in for possible ECMO, an ECMO alert is in place.

Notify the nurse coordinator for the ECMO unit, Sue Hix, RN (beeper 252-5852.)

Notify the physician coordinator for the NICU ECMO unit, Dr. Bill Walsh (835-0619.)

Notify the pediatric surgeons.

Notify the pediatric cardiologists for a stat Echocardiogram.

Notify the pediatric radiologists for a stat Head Ultrasound.

While the infant is waiting to be placed on ECMO, obtain the following labs:

  • Comprehensive Metabolic Profile (1.5 ml in a red top tube)

  • Ionized Calcium (0.3 ml in a blood gas syringe)

  • CBC with Differential and Platelets (0.5-1 ml in a purple top tube)

  • ACT

  • PT/PTT and Fibrinogen (2 ml in a blue top tube)

  • STAT Basic Metabolic Profile (0.5 ml in a red top bullet-send orange requisition)

  • Blood Type and Cross

  • Blood culture, if not already done

  • Newborn State Screen

This information can be also be found in the 2001 NICU Manual pg. 3-9.
