A 39-week gestation male neonate is born via spontaneous vaginal delivery to a 28-year-old primigravida. The pregnancy was uncomplicated. At birth, the neonate is limp, apneic, and cyanotic. Place the following steps of neonatal resuscitation in the correct chronological order of execution according to standard neonatal resuscitation guidelines, assuming the neonate's clinical status does not improve and the heart rate remains consistently below 60/min despite each successive intervention.
- 1Provide warmth, dry the infant, position the airway, and stimulate
- 2Initiate positive-pressure ventilation (PPV) and attach a pulse oximeter
- 3Perform ventilation corrective steps to ensure adequate chest movement
- 4Commence chest compressions coordinated with PPV using 100% oxygen
- 5Administer intravenous epinephrine via an umbilical venous catheter
Cevap
The correct sequence is: initial steps (warmth, drying, stimulation) -> initiate PPV -> perform ventilation corrective steps -> commence chest compressions -> administer intravenous epinephrine.
The Neonatal Resuscitation Program (NRP) algorithm dictates a specific sequence to ensure that the primary cause of neonatal compromise—respiratory failure and hypoxia—is addressed first. The sequence begins with initial steps (warmth, drying, stimulation, clearing airway). If the infant remains apneic or the heart rate is < 100/min, PPV is initiated. If PPV fails to increase the heart rate and move the chest, ventilation corrective steps are performed. Only after establishing effective ventilation (chest movement) for 30 seconds, if the heart rate remains < 60/min, are chest compressions started alongside 100% oxygen. Finally, if the heart rate remains < 60/min after 60 seconds of coordinated compressions and effective PPV, intravenous epinephrine is administered.

Anahtar Kavram
Neonatal resuscitation follows a strict stepwise progression focused primarily on establishing effective ventilation, as hypoxia is the most common cause of neonatal bradycardia.
