ABSTRACT. Objective. None of the 20 previously re-
ported infants weighing <750 g at birth who received
cardiopulmonary resuscitation (CPR) in the delivery
room (DR) survived. To clarify whether such resuscita-
tion is futile in our center, we evaluated our experience
with DR-CPR over a 4-year period.
Study Design. We retrospectively reviewed the out-
comes of all inborn infants with birth weights <1000 g at
University of California, San Digeo Medical Center from
January 1993 to December 1996. Surviving infants and
matched control infants were followed for <40 months’
adjusted age using standardized neurodevelopmental as-
sessments.
Results. Of the infants with birth weight <1000 g
born during this period, 29% (51/177) died, including 44%
of those <750 g and 16% of those >750 g. Overall, 19
infants received DR-CPR, of whom 12 were <750 g. Of
the infants who received DR-CPR, 79% (15/19) survived,
including 10 of 13 infants <750 g and 5 of 6 infants >750
g. Of the 15 survivors, 10 were followed beyond 10
months’ adjusted age (median: 28 months). At last exam-
ination, 70% were both neurologically and developmen-
tally normal. Two infants had cerebral palsy with mild
cognitive and severe motor developmental delay. Of 7
infants with birth weight <750 g, 6 had normal neurode-
velopmental outcomes. The mean composite mental and
motor scores of DR-CPR survivors were 93 10 and 89
25, respectively. No differences were found in neurologic
or developmental outcome between DR-CPR survivors
and control infants matched for gestational age, sex, and
year of birth.
Conclusions. Our results indicate that intact survival
is possible for infants weighing <750 g at birth after

ccording to American Academy of Pediatrics
guidelines, cardiac compressions and intra-
tracheal or intravenous epinephrine are indi-
cated for neonatal resuscitation when severe brady-
cardia does not resolve with effective positive
pressure ventilation and 100% oxygen or when the
infant is born with no heart rate.

However, there are
no specific recommendations regarding the use of
such resuscitative efforts for extremely low birth
weight (ELBW) or extremely immature infants.
No intact survivors have been described in pub-
lished literature to date for infants with birth weight
750 g or 28 weeks’ gestation who received delivery
room cardiopulmonary resuscitation (DR-CPR).

Despite these observations, current clinical practice
includes DR-CPR for ELBW infants. To determine
whether ELBW infants survive DR-CPR without sig-
nificant neurodevelopmental abnormality, we re-
viewed the neonatal and early childhood outcomes
of ELBW infants born over a 4-year period in our
institution who received CPR including epinephrine
and/or chest compressions in the delivery room
(DR).
METHODS
A retrospective chart review was conducted for all inborn
infants with birth weight 1000 g from January 1993 through
December 1996. Information was obtained regarding the DR-CPR,
Apgar scores at 1 and 5 minutes, evidence of neonatal central
nervous system injury, survival to discharge, and neurodevelop-
mental follow-up. Infants with lethal congenital malformations or
23 weeks’ gestational age were excluded. Gestational age, re-
corded as completed weeks, was determined from menstrual
dates confirmed by early obstetrical ultrasound. If obstetrical ul-
trasound confirmation was unavailable, gestational age was de-
termined using the clinical estimate of the attending neonatologist
that was recorded on admission.
Infants were considered to have received CPR if chest compres-
sions and/or intratracheal or intravenous epinephrine were used
in the DR for resuscitation.
Neonatal central nervous system abnormalities, identified by
echoencephalography, included intraventricular hemorrhage
(IVH) (grades 0 – 4),
7
ventricular dilatation (mild: 10 –11.9 mm,
moderate: 12.0 –14.9 mm, and large: 15 mm),
8
and echolucencies
(small/large). White matter injury was defined as the presence of
grade 4 hemorrhage, echolucencies, or ventricular dilatation un-
related to hemorrhage.
DR-CPR survivors were enrolled at discharge in the University
of California, San Diego (UCSD) Infant Special Care Follow-Up
Program and were followed longitudinally from 4 to 40 months’
adjusted age (AA). Each DR-CPR survivor followed for 10
months’ AA was matched for gestational age, sex, and year of
birth with a control infant who had not received CPR at any time
before discharge from UCSD and also was enrolled in the Infant
Special Care Follow-Up Program and followed for 10 months’
AA. Neurodevelopmental assessments included the Amiel-Tison
