Antepartum and Intrapartum Assessment and Care
Normal fetal heart rate baseline is 110-160 bpm; baseline bradycardia is <110 bpm for ≥10 minutes, tachycardia is >160 bpm for ≥10 minutes.
Category I tracing: baseline 110-160 bpm, moderate variability (6-25 bpm), no late or variable decelerations, with or without accelerations and early decelerations.
Category III tracing includes absent variability with recurrent late or variable decelerations, bradycardia, or a sinusoidal pattern; it requires prompt evaluation and intrauterine resuscitation.
Accelerations at ≥32 weeks: ≥15 bpm above baseline lasting ≥15 seconds; before 32 weeks: ≥10 bpm lasting ≥10 seconds.
Uterine tachysystole is >5 contractions in 10 minutes averaged over 30 minutes; treatment is maternal repositioning, IV fluid bolus, and reduction or discontinuation of oxytocin.
Variable decelerations reflect umbilical cord compression; late decelerations reflect uteroplacental insufficiency; early decelerations mirror contractions from head compression and are benign.
Tocolytic/acute intrauterine resuscitation sequence: stop oxytocin, left lateral positioning, IV crystalloid bolus, oxygen if hypoxemic, and consider terbutaline for tachysystole.
Group B streptococcus prophylaxis: penicillin G is first-line; cefazolin for non-anaphylactic penicillin allergy; clindamycin only if susceptibility testing confirms sensitivity.
Transition to Extrauterine Life and Resuscitation
NRP initial steps for a non-vigorous newborn: warm, dry, stimulate, position airway; suction only if airway obstruction is suspected.
Apnea or gasping, heart rate <100 bpm, or poor tone after initial steps warrants positive pressure ventilation at 40-60 breaths per minute.
Compressions begin when heart rate remains <60 bpm after at least 30 seconds of effective ventilation; ratio is 3 compressions to 1 breath, 90 compressions and 30 breaths per minute.
Epinephrine dose in neonatal resuscitation is 0.01-0.03 mg/kg IV/IO of 0.1 mg/mL solution; endotracheal dose is 0.05-0.1 mg/kg of 1 mg/mL solution.
Targeted preductal oxygen saturation: about 60-65% at 1 minute, 70-75% at 2 minutes, 80-85% at 3 minutes, 85-95% at 5 minutes, and 90-95% by 10 minutes.
Volume expansion in neonatal resuscitation is 10 mL/kg of normal saline or blood over 5-10 minutes, indicated for hypovolemia or blood loss.
Apgar score components are heart rate, respiratory effort, muscle tone, reflex irritability, and color; it is assigned at 1 and 5 minutes and does not guide resuscitation.
Delayed cord clamping for at least 30-60 seconds is recommended for term and preterm infants not requiring immediate resuscitation.
Respiratory System
Surfactant deficiency in respiratory distress syndrome produces decreased compliance, atelectasis, and ground-glass infiltrates with air bronchograms on chest radiograph.
Transient tachypnea of the newborn presents within hours of birth with tachypnea, mild hypoxemia, and perihilar streaking or fluid in fissures; it usually resolves within 24-72 hours.
Meconium aspiration syndrome risk increases with thick meconium and fetal distress; management includes airway clearance and respiratory support as needed.
Bronchopulmonary dysplasia is defined in infants born <32 weeks as oxygen requirement for ≥28 days, graded by respiratory support at 36 weeks postmenstrual age.
Physiologic nadir of arterial oxygen tension occurs at 24-48 hours of life and may fall to 50-70 mmHg in preterm infants.
Apnea of prematurity is a pause in breathing ≥20 seconds, or shorter with bradycardia or desaturation, and is treated with caffeine citrate.
Nasal CPAP is preferred initial support for preterm infants with respiratory distress; intubation and surfactant are indicated for escalating oxygen and work of breathing.
Oxygen saturation targets for preterm infants receiving supplemental oxygen are typically 90-95% to reduce retinopathy of prematurity risk.
Cardiovascular System
Ductal closure occurs functionally within hours to days after birth; anatomic closure takes weeks, and patency is maintained by prostaglandin E1 and low oxygen tension.
Prostaglandin E1 infusion at 0.01-0.1 mcg/kg/min maintains ductal patency in ductal-dependent lesions such as pulmonary atresia and critical coarctation.
Ductal-dependent lesions presenting with cyanosis include transposition of the great arteries, pulmonary atresia, tricuspid atresia, and tetralogy of Fallot with severe pulmonary stenosis.
Ductal-dependent systemic lesions include hypoplastic left heart syndrome, critical aortic stenosis, and interrupted aortic arch; they present with shock and diminished pulses.
Normal neonatal heart rate is 120-160 bpm awake; sinus bradycardia is <90 bpm and may require evaluation for congenital heart block.
Hyperoxia test: an arterial oxygen tension >150 mmHg after 100% oxygen suggests pulmonary rather than cyanotic cardiac disease.
Closure of a patent ductus arteriosus may be achieved with indomethacin or ibuprofen; contraindications include renal failure, thrombocytopenia, and necrotizing enterocolitis.
Hypoplastic left heart syndrome initial management includes prostaglandin E1 and avoidance of excessive pulmonary blood flow by limiting supplemental oxygen.
Neurologic System
Hypoxic-ischemic encephalopathy staging by Sarnat includes stage I (mild), stage II (moderate), and stage III (severe); therapeutic hypothermia is indicated for moderate to severe HIE.
Therapeutic hypothermia is initiated within 6 hours of birth, targets 33.5-34.5 degrees Celsius for 72 hours, and requires sedation, monitoring, and slow rewarming.
Neonatal seizures may present as subtle, clonic, tonic, or myoclonic movements; electroencephalography is required for confirmation because clinical signs are unreliable.

Acute kidney injury is staged by creatinine rise and urine output; causes include asphyxia, sepsis, nephrotoxic drugs, and obstructive lesions.
Hematology and Immunology
Physiologic anemia of infancy occurs at 8-12 weeks in term infants and 4-8 weeks in preterm infants due to low erythropoietin and shortened red cell lifespan.

Maternal immunoglobulin G crosses the placenta and provides passive immunity; immunoglobulin A is present in breast milk and protects the intestinal mucosa.
Newborn screening for severe combined immunodeficiency uses T-cell receptor excision circles on the dried blood spot.
Physiologic nadir of platelets is not expected; platelet count <150,000/microliter requires evaluation for sepsis, alloimmune destruction, or congenital infection.
Infectious Disease and Sepsis
Early-onset sepsis presents within 72 hours and is associated with maternal group B streptococcus colonization, prolonged rupture of membranes, chorioamnionitis, and prematurity.
Group B streptococcus prophylaxis is indicated for maternal colonization, previous infant with invasive disease, or unknown status with rupture of membranes ≥18 hours or intrapartum fever.
