Choosing a caregiver Current Lecture1. Developmental periods a. Fetal period: (9-338 weeks) - Fetus becomes larger- Body systems change - Brain begins to functionThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Finishing touches- sight, hearing, respiration, digestion 2. Factors in healthy prenatal development - Infections disease (HIV/AIDS)- Nutrition of mother - Emotional stress of mother - RH blood factor- blood condition where there is incompatibility between blood ofmother and blood of baby - Sperm health - Age 3. Impact of teratogens (environments, and their effects on baby)- Depends on genotype - Changes over course of prenatal development - Affects specific aspects of prenatal development - Depends on the dose - May not be evident in birth (cognitive development)4. Teratogenic drugs a. Alcohol: FAS, cognitive development, heart damage, growth retardation b. Aspirin: deficient in intelligence, attention, and motor skills c. Caffeine: lower birth weight, decreased muscle tone d. Cocaine/heroine/meth :retarded growth, irritability in newborns, impaired central nervous system, brain damage, miscarriage, prematurity, stillbirth, childhood defects in memory and languagee. Nicotine: (limits amount of oxygen getting to baby) retarded growth, facial deformitiesf. Marijuana: impaired central nervous system, brain damage, miscarriage, prematurity, stillbirth, childhood defects in memory and language5. Diseases and consequences a. HIV/AIDS: frequent infections, hierological disorder, death, encephalitis, enlarged spleen, blood clotting b. Genital herpes : encephalitis, enlarged spleen, blood clotting c. Rubella : mental retardation, damage to eyes, ears, heartd. Syphilis : death(if left untreated), damage to central nervous system, bones teeth6. Outcomes related to teratogens- Small for gestational age- Miscarriage, stillbirth - Placenta abruption- Stroke inside the womb - Heart and lung defects- CNS defects- brain, tremors - Addiction - SIDS- Attachment disorders 7. Prenatal decisions a. How important is prenatal care?: very important. I million women worldwide die each year due to pregnancy or childbirth complications.b. Types of caregivers: - Obstetrician: example: OBGYN- Family physician - Nurse midwife: has a degree in nursing usually with additional midwife training, and has hospital privileges- Lay midwife: does not usually have a medical degree, no guarantee that they have been given any training, do not have hospital privileges c. Choosing a caregiver: be careful when choosing a caregiver, some may not know exactly what they are doing, check with hospital staff for good doctors, and credible
