-name of picture -name the position of patient -ues for what -How to do speculum Examination - is it most common 1- Cusco’s or bivalve speculum 2-women in the dorsal position 3-examine the cervix 4-Use a warm and well lubricated speculum. The labia minora must be adequately parted with the left hand. Insert the speculum upwards and backwards (direction of vagina) Advance into vagina fully. Directly visualize as you open the plates to expose the cervix. If cervix not seen: close plates, withdraw slightly, change direction and open again. 5- Cusco’s bivalve is more frequently used

Also, when progesterone is available, the inhibitory effect of estrogen is multiplied, even though progesterone by itself has little effect. These feedback effects seem to operate mainly on the anterior pituitary gland directly, but they also operate to a lesser extent on the hypothalamus to decrease secretion of GnRH Hormone inhibin from the corpus luteum inhibits FSH and LH Secretion Hormone activin from the stimulates FSH Secretion FSH R progestins activin estrogens + Reproductive tract
19
when secretion throughout the sexual life of the female?
The increasing levels of estrogen secretion at puberty, the cyclical variation during the monthly sexual cycle, the further increase in estrogen secretion during the first few years of reproductive life, the progressive decrease in estrogen secretion toward the end of reproductive life, and, finally, almost no estrogen or progesterone secretion beyond menopause.

31
Delivery by Extension: As the fetal head reaches the maternal symphysis pubis it hitches under the bone. The pressure by the uterine contractions causes the neck of the baby to get extended
32
External Rotation: The shoulders rotate into an oblique or frankly anterio-posterior orientation with further descent. This encourages the fetal head to return to its transverse position. This is also known as Restitution .

HL Shoulder Dystocia A review of the risks, physiology, management, and prevention of Shoulder Dystocia Next Slide
73
PATHOPHYSIOLOGY The anterior shoulder can then slide under the symphysis pubis for delivery. If the fetal shoulders remain in an anterior-posterior position during descent or descend simultaneously rather than sequentially into the pelvic inlet, then the anterior shoulder can become impacted behind the symphysis pubis and/or the posterior shoulder may be obstructed by the sacral promontory. Then you get the dreaded “Turtle Sign” of doom. Next Slide

HELPERR Mnemonic The HELPERR mnemonic is a clinical tool that offers a structured framework for coping with shoulder dystocia. These maneuvers are designed to do one of three things: Increase the functional size of the bony pelvis through flattening of the lumbar lordosis and cephalad rotation of the symphysis (i.e., the McRoberts maneuver) Decrease the bisacromial diameter, the breadth of the shoulders, of the fetus through application of suprapubic pressure. Change the relationship of the bisacromial diameter within the bony pelvis through internal rotation maneuvers. Next Slide

81
HELPERR Mnemonic E Evaluate for episiotomy:
Episiotomy should be considered throughout the management of shoulder dystocia but is necessary only to make more room if rotation maneuvers are required. Shoulder dystocia is a bony impaction, so episiotomy alone will not release the shoulder. Because most cases of shoulder dystocia can be relieved with the McRoberts maneuver and suprapubic pressure, many women can be spared a surgical incision. Next Slide
82
HELPERR Mnemonic L Legs (the McRoberts maneuver):
This procedure involves flexing and abducting the maternal hips, positioning the maternal thighs up onto the maternal abdomen. This position flattens the sacral promontory and results in cephalad rotation of the pubic symphysis. Nurses and family members present at the delivery can provide assistance for this maneuver. Click HERE for McRobert’s Diagram. Next Slide

84
HELPERR Mnemonic P Pressure (Suprapubic):
The hand of an assistant should be placed suprapubically over the fetal anterior shoulder, applying pressure in a cardiopulmonary resuscitation style with a downward and lateral motion on the posterior aspect of the fetal shoulder. This maneuver should be attempted while continuing downward traction. Click HERE for Diagram. Next Slide

86
HELPERR Mnemonic E Enter maneuvers (internal rotation):
These maneuvers attempt to manipulate the fetus to rotate the anterior shoulder into an oblique plane and under the maternal symphysis. Next Slide
87
"Enter" Maneuvers 1. 2. 3. 1. Rubin II At vaginal examination apply pressure as indicated. If shoulders move into the oblique diameter, attempt delivery. 2. Rubin II + Woods corkscrew maneuver If unsuccessful, add the Woods corkscrew maneuver and continue rotation in the same direction. Use both hands and apply pressure as indicated. If shoulders now move into the oblique, attempt delivery. If this is unsuccessful, continue rotation 180 degrees and deliver. 3. Reverse Woods corkscrew maneuver If the last maneuver is unsuccessful, change to reverse Woods corkscrew maneuver. Slide fingers down to back of posterior shoulder and attempt 180-degree rotation in the opposite direction. Next Slide
88
HELPERR Mnemonic R Remove the posterior arm:
Removing the posterior arm from the birth canal also shortens the bisacromial diameter, allowing the fetus to drop into the sacral hollow, freeing the impaction. The elbow then should be flexed and the forearm delivered in a sweeping motion over the fetal anterior chest wall. Grasping and pulling directly on the fetal arm may fracture the humerus.

HELPERR Mnemonic R Roll the patient:
The patient rolls from her existing position to the all-fours position. Often, the shoulder will dislodge during the act of turning, so that this movement alone may be sufficient to dislodge the impaction. In addition, once the position change is completed, gravitational forces may aid in the disimpaction of the fetal shoulders. Click HERE for Diagram. Next Slide

Complications of Shoulder Dystocia
Maternal Postpartum hemorrhage Rectovaginal fistula Symphyseal separation or diathesis, with or without transient femoral neuropathy Third- or fourth-degree episiotomy or tear Uterine rupture Fetal Brachial plexus palsy Clavicle fracture Fetal death Fetal hypoxia, with or without permanent neurologic damage Fracture of the humerus Next Slide
93
Prevention Evidence is lacking to support labor induction or elective cesarean delivery in women without diabetes who are at term when a fetus is suspected of having macrosomia. In two studies of 313 women without diabetes, induction for suspected fetal macrosomia did not lower the rates of shoulder dystocia or cesarean delivery, nor did it improve the rates of maternal or neonatal morbidity. While labor induction in women with gestational diabetes who require insulin may reduce the risk of macrosomia and shoulder dystocia, the risk of maternal or neonatal injury is not modified. Not enough evidence is available to routinely support elective delivery in this population. Next Slide
94
Prevention So, prophylactic cesarean delivery is not recommended as a means of preventing morbidity in pregnancies in which fetal macrosomia is suspected. Analytic decision models have estimated that 2,345 cesarean deliveries, at a cost of nearly $5 million annually, would be needed to prevent one permanent brachial plexus injury in a patient without diabetes who had a fetus suspected of weighing more than 4,000 g. Next Slide
95
Prevention One method of preliminary intervention for shoulder dystocia in a patient with risk factors involves implementing the "head and shoulder maneuver" to "deliver through" until the anterior shoulder is visible. This step is accomplished by continuing the momentum of the fetal head delivery until the shoulder is visible. After controlled delivery of the head, the physician proceeds with immediate delivery of the anterior shoulder without stopping to suction the oropharynx. Next Slide
