OF FACULTY OF FOREING STUDENTS

Content module 2.

LESSON 4 (6 hours)

 

Theme:

1. Obstetric hemorrhages in the first trimester of pregnancy. Ectopic pregnancy. (2 hours)

2. Obstetric hemorrhages in the second half of pregnancy, labor, and postpartum period. (2 hours)

 3. Intensive therapy and emergent care of obstetric hemorrhages. (2 hours)

 

Place of training: educational rooms, hospital wards.

Aim: be able to perform physical examination of the patients with uterine haemorrhage in the third trimester of pregnancy, first and second stages of labor. Learn the main causes, clinical signs and symptoms, methods of treatment in the patients with Placenta Previa and Abruptio Placentae. To learn the causes, clinical signs and features, diagnosis, prevention and treatment of the hemorrhages in the third stage of labor and postpartumto learn clinical signs and symptoms of terminal states in obstetrics, diagnostic workup of the terminal states establishment.

Professional orientation of students: Hemorrhage during the antepartum, intrapartum, or postpartum period is a life-threatening emergency for the mother and/or fetus. Early antepartum hemorrhage (before 20 weeks gestation) can be related to abortion/miscarriage, ectopic pregnancy, or gestational trophoblastic disease; late antepartum hemorrhage (after 20 weeks gestation) may result from placental abruption and placenta previa. Intrapartum hemorrhage is most commonly due to placental abruption, or to uterine rupture, uterine inversion, invasive conditions of the placenta, or complications of Cesarean birth. Postpartum hemorrhage is defined as blood loss greater than 500 ml in a vaginal delivery or 1000 ml in a Cesarean birth; early postpartum hemorrhage occurs during the first 24 hours after delivery; late postpartum hemorrhage occurs after the first 24 hours after delivery. The most common cause of postpartum hemorrhage is uterine atony; however, lacerations, hematomas, and subinvolution of the uterus can also cause postpartum hemorrhage. MD who understand how to assess, plan, intervene, and evaluate outcomes for perinatal hemorrhage are in the position to prevent the major tragedies that can accompany hemorrhage in pregnancy and shortly afterward.

1. Methodology of Practical Class: 9.00-12.00.

Tasks for practical work 1.

Obtain a set of vital signs from the mother, including BP, pulse and temperature.

·         Elevated BP suggests the presence of pre-eclampsia.

·         Elevated BP may be defined as a persistently greater than 140 systolic or 90 diastolic. Usually, if one is elevated, both are elevated.

·         Elevated temperature suggests the possible presence of infection.

·         Many pregnant women normally have oral temperatures of as much as 99+. These mild elevations can also be an early sign of infection.

·         While a pregnant pulse of up to 100 BPM or greater may be normal, rapid pulse may also indicate hypovolemia.

8. Correct answers of test evaluations and situational tasks:

1. A.

2. D.

3. C. D.

4. Abruptio placentae.

 5. Cesarean section.

6. She has a placenta previa and will definitely require cesarean section. The ultrasound is consistent with a partial placenta previa. Because the growth of the upper and lower uterine segments may results in the placenta “migrating away” from the cervical os, it is too early to be certain that cesarean section will be required.
