Lecture Notes on Pregnancy and Reproductive Health
Key Hormones and Pregnancy Maintenance
- Progesterone: Hormone responsible for maintaining pregnancy.
Placenta Functions
- Villous Trophoblast: Part of the placenta responsible for gas and nutrient exchange.
Ectopic Pregnancy
- Fallopian Tube: Most common site for ectopic pregnancy.
Early Signs and Stages of Pregnancy
- Amenorrhea: An early sign of pregnancy.
- Cervical Dilation: Occurs during the first stage of labor.
Fetal Health
- Fetal Oxygenation: Best position during labor is left lateral.
- Normal Fetal Heart Rate: 110 to 160 BPM.
Pregnancy-Related Conditions
- Preeclampsia: Characterized by high blood pressure and proteinuria.
- Gestational Diabetes: Advanced maternal age is a risk factor.
- Placenta Previa: Condition where the placenta covers the cervix.
Duration and Fertility
- Normal Pregnancy Duration: 40 weeks.
- Fertilization: Most commonly occurs in the fallopian tube.
Labor and Delivery
- Cesarean Section: Surgical procedure to deliver a baby through the abdominal wall.
- Ideal Fetal Presentation for Vaginal Delivery: Breech.
- Pelvic Shape Favorable for Vaginal Delivery: Gynecoid.
Postpartum and Newborn
- Postpartum Hemorrhage: Leading cause of maternal mortality.
- Meconium: Term for a newborn's first stool.
- Fontanel: Soft spot on a newborn's head.
Tests and Procedures
- Pap Smear: Test used to detect cervical cancer.
- Positive Pregnancy Test: Indicated by multiple factors.
Hormones and Lactation
- Oxytocin: Triggers milk ejection.
- Prolactin: Responsible for milk production.
Risk Factors and Complications
- Placenta Accreta: Abnormal implantation of the placenta.
- Cervical Incompetence: Risk factor for preterm labor.
- Polyhydramnios: Characterized by excessive amniotic fluid.
Maternal-Fetal Health
- Uterine Atony: Common cause of postpartum hemorrhage.
- O Negative Blood Type: May lead to hemolytic disease of the newborn.
Terminology
- Quickening: Term for fetal movement felt by the mother.
- Involution: Return of the uterus to its pre-pregnancy size.
- Gravida: Refers to the number of pregnancies.
- Breech Presentation: Increases the risk of umbilical cord prolapse.
Emergency Situations
- Fetal Distress: Indication for an emergency C-section.
- Bradycardia: A sign of fetal distress.
- Blurry Vision: A sign of impending eclampsia.
These notes summarize the main points from the lecture on pregnancy and reproductive health, focusing on hormonal roles, pregnancy signs, fetal health, labor stages, and pregnancy-related conditions.
