Trends in Maternal-Infant Trends in Maternal-Infant Nursing CareNursing Care

Development standard of care, certification, advanced practice nurses

Home Health care for postpartum women, discharge from Hops. 12-24 hours after delivery, high risk infants discharge home earlier than before

Consumer involved in the childbearing care: Child birth class, sibling present, breast-feeding, birthing environment (LDR, LDRP), father’s involvement, parents leave option for family with newborn

Maternal Nursing concerns areasMaternal Nursing concerns areas

Prenatal care Low birth weight Mother and infant with HIV infection Adolescent pregnancy Drug and substance abuse during pregnancy Social/family stress and impacts to pregnant

women and family Use and care for pregnant women

Special Issues in Women’s Special Issues in Women’s Health Health

Violence Sexual Transmitted Diseases: HIV/AIDS 86% of pediatric AIDS cases are

transmitted through vertical transmission of HIV

Substance abuse Other diseases: Heart diseases, cancer,

osteoporosis, eating disorders

The Menstrual CycleThe Menstrual Cycle

Ovarian Cycle: 1. Follicular phase: stimulated with FSH to promote

the development of follicles Estrogen-follicle mature-negative feedback to

hypothalamus and anterior pituitary gland – inhibiting FSH secretion

2. Ovulation: increase in body temperature (progesterone secretion), fern pattern of the cervical mucus, spinnbarkeit “elasticity of the ovulatory”due to secretion of the estrogen

The Menstrual CycleThe Menstrual Cycle

3.Luteal Phase: Corpus luteum and anterior pituitary gland will secret luteinizing hormones (the decrease in Estrogen and progesterone – positive feedback to Hypothalamus and anterior pituitary- stimulating the secretion of FSH

4. Premenstrual phase: Decline in estrogen and progesterone

The Menstrual CycleThe Menstrual Cycle

Endometrial Cycle:

1. Proliferative phase

2. Secretary phase

3. Menstrual phase

QuestionQuestion

Family System Changes During The Family System Changes During The Childbearing CycleChildbearing Cycle

StructurePowerBoundariesAffect or feelingsIntergenerational patterns and rolesCommunication patternsCultural background and riturals

Bonding and AttachementBonding and Attachement

Bonding is affected by Maternal-Sensitive period.

Attachment is developed through out the first year of life.

Important for nursing practice: do not make inaccurate judgment, understand that childbearing is a major transition I the life of a family

Nursing intervention for the Nursing intervention for the three Phases of crisis three Phases of crisis

Precrisis: Predictable and development events in the life cycle

1. Discuss change with family structure, adding new member

2. Assess risk factors, past coping and problem solving

3. Implement health teaching4. Implement health promotion and maintenance

strategies

Nursing intervention for the Nursing intervention for the three Phases of crisisthree Phases of crisis

Crisis: Coping strategies not sufficient to deal with changes in family structure and problem in development

1. Clarify the problem2. Assist the family in going an understanding of the

situation3. Acceptance of the family4. Use appropriate interpersonal and institutional

resources5. Assess family to express feeling & ways of solving

problem

Nursing intervention for the Nursing intervention for the three Phases of crisisthree Phases of crisis

Postcrisis: Crisis has been resolved, leading to a higher, the same, or lower of family function

1. Support the family in its new strategies of resolution

2. Emphasize growth potential in solutions

3. Attempt to reverse or lessen effects of maladaptation through appropriate rehabilitative effort or therapy

Psychosocial aspects of Psychosocial aspects of childbearing Theorieschildbearing Theories

1. Psychosocial Change in the mother: Accepting the pregnancy– Symbolic meaning of the pregnancy– Self-image and body image during pregnancy

Psychosocial aspects of Psychosocial aspects of childbearing Theorieschildbearing Theories

2. Role Assumption and maternal AdaptationMaternal IdentityMaternal role attainment: Motivation for

motherhood, preparation for motherhood, conflict resolution, maternal attachment behavior, relationship with mother

Role conflict and attainment of the maternal role

Role conflict and attainment of Role conflict and attainment of the maternal rolethe maternal role

Inability to achieve the “good Mother”roleLack of knowledge and preparation for the

maternal roleEstablishing a relationship with the fetus

Maternal Ambivalence in PregnancyMaternal Ambivalence in Pregnancy No questions asked about pregnancy, labor and

delivery, infant care No interest in fetus Past negative experience with pregnancy or labor and

delivery Denial of pregnancy and fetal movement Pregnancy and parenthood interfering with life style Continue activities that may hurt the fetus (smoking or

drinking) Reporting persistent and many physical complains.

Rh ImmunizationRh Immunization

Check by Indirect Coombs test to detect antibodies in the serum that target red blood antigens to cause fetus hemolysis

Antibody titer > 1:16 indicates possibility of severe hemolytic diseases

Mother with Rh-negative: should receive Rhogam within 72 hours (any invasive procedure that may cause the mixing of the maternal blood with fetus)

3. Psychosocial Change in the father: • Development of the father role• Participation in the childbearing cycle• Father-infant interactions and the father role • “The Couvade Syndrome”-bodily symptoms

experienced by a father during the course of his partner’s pregnancy.

Pregnancy and weight gain Pregnancy and weight gain

First Trimester: 2-4 pounds (0.9-1.8 kg), 1 pound per week (0.45 kg) during 1st & 2nd trimester

Total weight gain 13.18 kg or 29 pounds

Pregnancy and NutritionPregnancy and Nutrition

Obesity: recommend to gain wt 7-11.5 kg Underweight Teenage pregnancy: low wt gain during

pregnancy, associated with LBW infant 19% of the baby wt < 2000 gram decrease 7.4% of LWB infant if wt gain improve

to 11kg (25 lbs). Frequent meal skipping and consumption of fast

food (high salt, sugar, low vit and minerals)

Risk of Obesity to pregnancy Risk of Obesity to pregnancy Gestational diabetes Urinary tract infections Inadequate weight gain Wound infection Thromboembolism PIH Fetal monitoring difficulty Prolonged labor Fetal Macrosomia Birth trauma

Question-NutritionQuestion-Nutrition

pain, diarrhea, Vaginal bleeding Decrease or cessation of fetal movement

Assessment for Neural Tube Assessment for Neural Tube DefectsDefects

“open” neural tube defects leak alpha-fetoprotein (AFP)

Elevate AFP level in maternal serum and amniotic fluid may indicate the fetus has neural tube defects

Amniocentesis Amniocentesis

Performed around 15-18 weeks of gestation to identify genetic abnormality

Risk: 1. Trauma to the fetus, placenta, umbilical cord,

or maternal structures

2. Infection

3. Premature labor and spontaneous abortion

AmniocentesisAmniocentesis

Warning signs after receiving amniocentesis:

1. Body temperature elevation

2. Fluid leaking from the vaginal

3. Mild Cramping and abdominal aching

4. Decreased fetal movement

Chorionic Villus SamplingChorionic Villus Sampling

To detect genetic or chromosomal defectsCan be done in early pregnancy 9-10 weeks

gestationRisk: miscarriage 3.7-7.7%, 1.7%

discrepancy of result between villus karyotype and fetus, rupture amniotic sac, chorioamnionitis, oligohydramnios, intrauterine growth retardation

The Nonstress test The Nonstress test

Check fetus well-beingCheck fetal movement in relation to fetal

heart rate acceleration Reactive: HR acceleration with fetus

movement Non reactive: no HR acceleration with fetus

movement

Genetic Problem Genetic Problem

Autosomal Recessive Disorders: 25% of the Risk of passing the disorder to each of their

offspring. 1:4 chance of demonstrating the disorder, 50% change of being a carrier to the recessive trait, each child has 25% chances of not having the diseases and not being a carrier
