12.
Copyright © 2017,
2012 Pearson Education, Inc. All Rights Reserved. Anatomy and Physiology Review (3 of 20) • Female reproductive system (continued) – Menstrual cycle: ovaries and endometrium undergo cyclical monthly endocrine changes – After the uterine lining is shed, hormonal changes influence it to be rebuilt. – Ovulation: 14 days after first day of menstrual bleeding, mature follicle ruptures, discharging ovum into pelvic cavity near fallopian tube

2012 Pearson Education, Inc. All Rights Reserved. Anatomy and Physiology Review (4 of 20) • Pregnancy – If sperm is in fallopian tube during ovulation, fertilization may occur, resulting in pregnancy. – If pregnancy occurs, fertilized egg travels to uterus, where it is implanted in thickened endometrium. – Corpus luteum secretes hormones that support pregnancy until placenta develops.
15.
Copyright © 2017,
2012 Pearson Education, Inc. All Rights Reserved. Anatomy and Physiology Review (5 of 20) • Pregnancy (continued) – Fertilization (conception): union of spermatozoan and ovum produces zygote – 30 hours: fertilized ovum divides; 6 days: zygote enters uterine cavity; cells form blastocyst – Cells divide and migrate: extraembryonic membranes form (amniotic sac) – Villi in endometrium: allows maternal blood to pass and allows fetal gas exchange. – Placenta: temporary organ of pregnancy; fetus attached by umbilical cord
16.

2012 Pearson Education, Inc. All Rights Reserved.

Copyright © 2017,
2012 Pearson Education, Inc. All Rights Reserved. Anatomy and Physiology Review (8 of 20) • Pregnancy―maternal changes – Uterus increases in size; breasts prepare for lactation; distended uterus and abdomen more prone to trauma. – Blood volume increases by 45% to 50%; heart rate increases by 10 to 15 beats per minute. – Blood pressure may lower during first two trimesters, returns to normal in the third. Hypertensive disorder of pregnancy (preeclampsia)
22.
Copyright © 2017,
2012 Pearson Education, Inc. All Rights Reserved. Anatomy and Physiology Review (9 of 20) • Pregnancy―maternal changes (continued) – Pregnancy hormones reduce airway resistance. – Combined needs of fetus and mother; 20% increase in oxygen consumption by term – Tidal volume increases substantially; small increase in respiratory rate.
23.
Copyright © 2017,
2012 Pearson Education, Inc. All Rights Reserved. Anatomy and Physiology Review (10 of 20) • Pregnancy (continued) – Morning sickness: nausea and vomiting of early pregnancy – Gastrointestinal system slows during pregnancy. – Urinary frequency is a common sign of pregnancy. – Glucose in urine: gestational diabetes – Protein in urine: preeclampsia – Sprains and joint injuries occur more readily.
24.
Copyright © 2017,
2012 Pearson Education, Inc. All Rights Reserved. Anatomy and Physiology Review (11 of 20) • Pregnancy (continued) – Braxton-Hicks contraction: late in pregnancy; intense, but painless, tightening of uterus – Level of oxytocin increases to point where contractions regular and sustained.

Assessment and Management of the Neonate (2 of 3) • APGAR score – Most newborns score between 7 and 10. – Score between 4 and 6: moderate distress – Score 3 or less: severe distress that requires bag- valve-mask ventilations with supplemental oxygen – Heart rate below 60 and does not respond to ventilations: start chest compressions – Hypoxia is the most common cause of bradycardia in newborns.

2012 Pearson Education, Inc. All Rights Reserved. Assessment and Management of the Neonate (3 of 3) • Assessing vital signs – Ideal heart rate: 140 to 160 – Strong cry indicates adequate respirations. – Respiratory distress: grunting; subcostal, intercostal, or supracostal retractions; seesaw respirations – Pulse oximetry recommended when resuscitation anticipated. – Temperature: 98°F to 100°F – Dry newborn and wrap in blankets; cover head. – If blood glucose level is below 60 mg/dL, consult medical direction.

Considerations in Neonatal Resuscitation (1 of 4) • Oxygen administration – Goal: SpO2 96%; Long-term administration of high concentrations of oxygen can cause complications in newborns. – Hypoxia is the primary reason for neonatal bradycardia. – Use blow-by oxygen; do not administer oxygen directly by mask or cannula.

2012 Pearson Education, Inc. All Rights Reserved. Considerations in Neonatal Resuscitation (2 of 4) • Airway management and ventilation – Do not use battery-powered or fixed electric suction in neonate. – Consider neonatal oropharyngeal airway for prolonged ventilation. – Use laryngeal mask airway (LMA) if ventilation by face mask is not effective. – Use neonatal bag-valve-mask device.

2012 Pearson Education, Inc. All Rights Reserved. Considerations in Neonatal Resuscitation (3 of 4) • Chest compressions – Initiate if heart rate less than 60 beats per minute and has not improved after assisted ventilation with supplemental oxygen for 30 seconds. – Use compression-to-ventilation ratio of 3:1 at rate of 90 compressions and 30 breaths per minute.

Considerations in Neonatal Resuscitation (4 of 4) • Fluids and medications – Medications rarely used in newborn resuscitation – 2 mL/kg of 10% dextrose, IV or IO, may be indicated during post resuscitation care. – 10 mL/kg IV or IO fluid infusion; Avoid rapid infusion to prevent brain hemorrhage with premature newborns.

Neonatal Complications and Defects (1 of 5) • Prematurity – Neonate born prior to 37 weeks’ gestation – Neonate is not considered viable until 24 weeks’ gestation and 450 grams in weight. – Resuscitate any newborn delivered after 20 weeks’ gestation, unless death obvious.
