Introduction
Under normal circumstances, the transitionfrom womb to world is a series of dramatic andrapid physiologic changes leading to the birth of aninfant prepared to continue the processes of
growth and development. The goal of delivering ahealthy infant intact ready to continue normaldevelopment is, unfortunately, not alwayspossible.
At birth, neonatal resuscitation may be
necessary. However, because it is not possible topredict every infant who may require resuscitation,the ability to conduct an eective resuscitation isan integral part of the considerations and planningfor any delivery. Regardless of level of care, a
trained and eperienced team, readily available, is

Responses to hypoia
"n the normal fetal circulation,blood returning to the heartfrom the body and placenta isprimarily shunted through theforamen ovale to the left side ofthe heart facilitatingoygenated blood to going tothe head and the heart. #loodthat reaches the right ventricleis shunted through the ductusarteriosus to the aorta,bypassing the lungs as a resultof a high pulmonary vascularresistance. This serves the
fetus well as the ma$or organ ofgas echange is the placenta

"f an infant is in primary apnea andeposed to oygen when gaspingrespirations ensue, eposure tooygen may be suf0cient to reversethe process. However, once theinfant reaches secondary apnea,positive pressure ventilation is
required to initiate spontaneousventilation.&urthermore, the longer the durationof secondary apnea, the longer it willta-e for spontaneous respiratory

The infant should be throughly dried with allwet blan-ets removed to reduced evaporativeheat loss.
"mmediately after birth, the infant with anydegree of compromise, or for whom there isany concern, should be placed in themicroenvironment of a preheated radiant
warmer.

There are three things that can bedone to help diminish heat loss inthe preterm3small infant. The 0rsttwo should be done before theanticipated delivery4 %i) increase thetemperature of the delivery room
and %ii) ma-e sure that the radiantwarmer is pre heated before thebirth of the infant.
The premature and3or small infantrepresents an especially dif0cultproblem from the aspect oftemperature control.
for infants less than 5' wee-s, it is now recommended that consideration begiven to placing the infant in a standard, food quality ( gallon
polyethylene bag that can easily be obtained from a grocery store. A hole iscut in the closed end of the bag and the bag slipped over the baby with his or

The airway is normally clearedwith the use of a bulb syringe orsuction catheter. The mouth is
suctioned 0rst and then the nose.
This is done to 0rst clearsecretions in the mouth andpotentially prevent theiraspiration should deep breaths
occur with nasal suctioning.8entle suctioning of the mouthwill avoid the re9e bradycardiaassociated with stimulation of theposterior pharyn.

"f there is no immediate response to these supplemental methods,positive pressure ventilation should be promptly initiated. !ontinuedtactile stimulation in an unresponsive infant will not succeed and mayprolong the asphyial process. "f, after suctioning and tactilestimulation an infant ehibits apnea or a heart rate of : (;;beats3min, positive pressure ventilation should be initiated.
