Placenta Previa

Introduction and Definition00:00:02

The video introduces placenta previa as an abnormal implantation of the placenta where it implants lower in the uterus instead of the fundus, potentially blocking the cervical opening.

Types and Anatomy00:02:00

The speaker explains the four types of placenta previa: marginal, partial, and complete, noting that complete previa creates a full blockage for the baby's head during delivery.

Causes and Risk Factors00:04:15

Risk factors discussed include previous placenta previa, uterine scarring from C-sections or curettage, endometriosis, advanced maternal age, multi-fetal gestation, closely spaced pregnancies, and smoking.

Signs and Symptoms00:06:28

Key symptoms include painless bright red vaginal bleeding that occurs on and off due to micro-tears in the uterus, a soft non-tender uterus, higher than expected fundal height, and abnormal fetal positions like breech or transverse.

Treatment and Interventions00:08:52

Treatment involves monitoring via ultrasound, fetal heart rate, and labs, along with patient education to avoid vaginal exams and intercourse, strict bed rest, and potential cesarean delivery around 34 weeks.
