Time management is essential. Have back up alternatives !

In Nursing 2202 we are going to discuss how we go from

Sperm & ovum

30 HRS fertilized egg TO

And the implications for us as nurses! This is not a A & P class But we will do some review.

U.S. Infant Mortality Rates have decreased over time due to: regional transport for high risk deliveries improved screening for fetal abnormalities improvements in case management increases in early prenatal care.use of surfactants protective health behaviors - e.g., breastfeeding, not smoking, back to sleep - also contributed to this decrease.

Mortality rate for black infants remains more than twice the rate for white infants. Low birth weight rates have increased from 6.7% in 1984 to 8% in 1999. During this same decade, infant deaths due to prematurity/low birth weight increased.Deaths due to birth defects remained stable at 22%, respiratory distress syndrome and SIDS decreased.

Morbidity vs Mortality Morbidity & New Morbidity

Morbidity : the prevalence of illness & disease over a period of time

Denotes 3 things:1. Acute illness2. Chronic Disease3. Disability

New Morbidity : Problems besides disease or injury which affect individual’shealth. Examples include behavioral, social (family), educationalproblems.

Mortality - death.

Fetal Death: intrauterine death of a fetus of at least 20 weeks gestation with absence of any signs of life after birth. Neonatal death: death of an infant born with signs

of life up to 28 days after birth. Perinatal death : sum of fetal & neonatal deaths per 1000 live births. ** BEST indicator of perinatal careINFANT MORTALITY: the number of deaths per 1000 that occur in the first year of life.*** This the the statistic used by most countries. This is what is most seen in the Literature ALTHOUGH is not the best indicator of Perinatal care.Maternal Death: death of mothers per 100,000 due to complications of pregnancy, labor , delivery or postpartum.

All Women 1999= 7.4; 2000 = 7.3Leading Causes Pregnancy Related Death: hemorrhage, embolism, hypertension, infection, anesthesia related complications

Maternal Mortality Rate : approximately 7.5 per 100,000 in 1998 When compared to white women ; Black women have 4 times the risk fordying from complications of pregnancy and childbirth.One half of all deaths could be prevented with early detection. No significant changes since 1982 - fluctuated between 7 & 8 %.Hemorrhage, PIH, infection, and ectopic pregnancies account for most of the deaths.

Fetal mortality rate in 1998 was 6.7% improved from 6.8% White = 5.7% Black = 12.3%

Perinatal Mortality = 7.2% ; Whites = 6.2% , Blacks = 12.9%

Neonatal mortality = 4 .8% ; Whites = 4.0% , Blacks = 9.4% . | In 1990 was 5.7% |

Postneonatal Mortality = 2.4% ; Whites = 2.0% , Blacks = 4.4 %

The United States infant mortality rate ranked 26th among selected countries in 1996. The 1996 US infant mortality rate of 7.3 per 1,000 live births was more than twice as high as the number 1 ranked country Singapore, with a rate of 3.8. The 1998 preliminary US infant mortality rate was 7.2 per 1,000 live births

QUICK STATS FOR THE UNITED STATES:

- every 8 seconds a baby is born in the US- every hour 3 babies die- African American infants are more than twice likely to die before their first birthday as white infants-birth defects are leading cause of infant mortality- every 3.5 minutes a baby is born with a birth defect- each year 2,500 infants are born with defects of the brain & spinal cord- every 2 minutes a lowbirth weight baby is born- every year more than 4,200 babies are born weighing less than 1 pound- every minute a baby is born to a teen mother- each day 410 babies are born to mothers who started prenatal care in the 3rd

trimester or received no prenatal care at all-more than 1 in 9 infants is born preterm - less than 37 weeks gestation- the US infant mortality is higher than 25 other nations
