Study Notes
Teratogens and Their Effects
- Teratogens are substances or situations causing developmental abnormalities in a fetus.
- Exposure to viruses, smoking, or second-hand smoke increases risks like low birth weight, irritability, and possible stillbirth.
- Alcohol consumption throughout pregnancy can lead to fetal alcohol syndrome, impacting neurological and intellectual development.
- Radiation and some medications, including herbal remedies, pose risks during pregnancy.
Pregnancy Overview
- Pregnancy is divided into three trimesters, approximately three months each.
- Laboratory diagnosis of pregnancy involves detecting human chorionic gonadotropin (hCG) in plasma or urine.
Signs and Calculations
- Absolute signs later in pregnancy include detectable fetal heartbeat via auscultation or ultrasound.
- Estimated date of delivery (EDD) calculated using Naegele’s rule; adjustments needed for irregular cycles.
- Gestational age is usually two weeks longer than biological age based on the last menstrual period (LMP) with a typical duration of 280 days (40 weeks).
Gravidity and Parity
- Gravidity refers to the number of pregnancies, while parity indicates the number of viable pregnancies.
- Primigravida denotes a woman pregnant for the first time, whereas multipara refers to those who have completed two or more viable pregnancies.
Prenatal Diagnostics
- Amniocentesis entails checking amniotic fluid for disorders after 14 weeks, involving fluid withdrawal for chemical analysis and chromosome culture.
- Chorionic villi sampling (CVS) offers an earlier alternative for chromosomal examination in high-risk pregnancies.
Hormonal Changes During Pregnancy
- Estrogen and progesterone levels rise, aiding uterine development and pregnancy maintenance.
- Increased thyroid hormone production (thyroxine) to meet maternal and fetal needs raises metabolism, causing heat intolerance.
Reproductive System Adaptations
- Uterus size increases, with muscle cells hypertrophying, cervix and vagina becoming more vascularized, and the tissue softening.
- Increased cervical mucus forms a cervical plug, protecting uterine contents and leading to more acidic secretions.
Weight Gain and Nutritional Needs
- Average weight gain during pregnancy is 25-30 pounds (11-13 kg), accommodating enlarging uterus, breasts, and increased blood volume.
- Nutritional demands rise for proteins, carbohydrates, fats, and essential vitamins/minerals, particularly iron and calcium.
Digestive System Changes
- Common early pregnancy symptoms include nausea and vomiting, influenced by hormonal changes.
- Digestive tract motility decreases due to progesterone, causing slower stomach emptying and potential heartburn and constipation.
Cardiovascular Changes
- Blood volume increases significantly, including both fluids and erythrocytes to support the fetus.
- Heart rate may increase slightly with blood pressure dropping in early trimesters then rising to normal levels later.
- Pregnancy can lead to the development of varicose veins.
Hypertensive Disorders
- Preeclampsia involves rising blood pressure and signs of kidney dysfunction; can progress to HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets).
- Eclampsia presents extremely high blood pressure, potentially causing seizures or coma, and increasing stroke risk; may necessitate cesarean delivery.
Gestational Diabetes Mellitus
- Occurs in 2-5% of pregnancies, with high blood glucose levels posing risks in the first trimester.
- Newborns may be large for gestational age and experience issues like hypoglycemia after birth; glucose monitoring and proper management are crucial.
Placental Complications
- Placenta previa involves the placenta implanting low in the uterus, risking tearing and causing painless bright red bleeding.
- Abruptio placentae entails premature detachment of the placenta from the uterine wall, often presenting as abdominal pain with bleeding.
Blood Clotting and Complications
- Thromboembolism is common postpartum, where clots typically form in the legs or pelvis.
- Factors like movement, walking, and blood thinners can mitigate clotting issues; serious conditions may lead to disseminated intravascular coagulation (DIC) characterized by excessive clotting.
Adolescent Pregnancy Considerations
- Teen mothers face increased nutritional demands and heightened risk of complications, with common issues like anemia.
- Babies born to younger mothers are often smaller or preterm, and labor may be complicated due to underdeveloped pelvic structures.
Teratogens and Their Effects
- Teratogens are substances or situations causing developmental abnormalities in a fetus.
- Exposure to viruses, smoking, or second-hand smoke increases risks like low birth weight, irritability, and possible stillbirth.
- Alcohol consumption throughout pregnancy can lead to fetal alcohol syndrome, impacting neurological and intellectual development.
