Study Notes
Cranial Components
- Sutures: Fibrous joints connecting the bones of the skull.
- Fontanels: Soft spots on an infant's skull facilitating growth and brain development.
- Anterior Fontanel: The largest fontanel at the top of the head, typically closes between 12 to 18 months.
- Posterior Fontanel: Smaller fontanel that normally closes by 2 to 3 months of age.
Reflexes in Infants
- Rooting Reflex: Infant turns head toward stimulus when cheek is touched.
- Palmar Grasp Reflex: Infant grasps an object placed in their palm.
- Moro Reflex: Infant extends arms when startled and then retracts them.
- Babinski Reflex: Toes fan out when the sole of the foot is stroked.
Stages of Labor
- Latent Phase: The first stage of labor marked by the start of regular contractions.
- Expulsion Stage: The second stage of labor, during which the baby is born.
- Placental Stage: The third stage where the placenta is expelled.
Labor Terminology
- Deceleration Phase: Gradual decrease in intensity of contractions as delivery approaches.
- Cervical Dilation: Measurement of the cervix opening during labor, quantified in centimeters.
- Uterine Tone: Evaluation of how well the uterus contracts during labor.
- Membrane Tension: Pressure of amniotic fluid against membranes during labor.
- Cord Prolapse: Condition where the umbilical cord slips ahead of the presenting part.
- PROM: Premature rupture of membranes before labor begins.
- Bishop Score: Degree of cervical dilation and effacement during labor, assessing readiness for labor.
- Bishop Scoring System: Scoring system for evaluating cervix readiness for labor.
Delivery Methods
- Cesarean Section: Surgical delivery involving incision in the abdomen and uterus.
- Breech Presentation: Baby is positioned feet or buttocks first during delivery.
- Frank Breech: A specific breech delivery where the baby is delivered buttocks first.
- Assisted Delivery: Use of instruments such as forceps or vacuum extractor during delivery.
- Prolonged Labor: Labor lasting longer than 20 hours in nulliparous women.
Postpartum Considerations
- Involution: Period after delivery where the body returns to its non-pregnant state.
- Postpartum Assessment: Evaluation of mother's physical recovery and emotional adjustment after childbirth.
- Colostrum: First breast milk rich in antibodies produced following childbirth.
- Early Breastfeeding: Initial feeding crucial for bonding and nutrition.
Infant Conditions
- Erb’s Palsy: Birth injury resulting from damage to brachial plexus nerves during delivery.
- Craniosynostosis: Premature closure of cranial sutures leading to abnormal head shape.
- Microcephaly: Condition where a child's head is significantly smaller due to inadequate brain growth.
- Anencephaly: Neural tube defect characterized by the absence of cerebral hemispheres.
- Craniotabes: Localized softening of cranial bones often observed in first-born children.
- Caput Succedaneum: Scalp edema crossing suture lines due to birth pressure.
- Cephalhematoma: Collection of blood between the skull and periosteum that does not cross suture lines.
- Seborrhea: Also known as cradle cap, characterized by scaling and greasy patches on the scalp.
- Hydrocephalus: Accumulation of cerebrospinal fluid (CSF) in the brain.
- Communicating Hydrocephalus: CSF flows freely between the ventricles.
- Non-Communicating Hydrocephalus: Obstructed CSF flow due to blockage.
Intracranial Pressure and Vision
- Intracranial Hypertension: Elevated pressure in the skull that can cause brain damage.
- Frontal Bossing: Prominent forehead due to abnormal skull shape or growth.
- Sunset Sign: Indicator of increased intracranial pressure where the eyes appear to gaze downward.
- Visual Acuity: Clarity or sharpness of vision, often assessed in children.
- Myopia: Condition known as nearsightedness, where distant objects appear blurry.
Ear and Eye Assessment
- Ear Placement: Positioning of the outer ear related to head that may indicate genetic conditions.
- Low-Set Ears: Ears positioned lower than normal associated with certain syndromes.
