Definition(s)
„
Difficulty in the birth of the shoulders (Varney)
„
Vertex delivery in which gentle lateral head traction and
normal maternal pushing efforts fail to deliver the
shoulders, in the absence of other causes of dystocia or
slow progress (Piper & McDonald, 1994)
„
Further progress toward delivery is prevented by
impaction of the fetal shoulder within or above the
maternal pelvis (Seeds, 1991 quoted by Hall, 1997)

Incidence
„
.23% to 2.09% of all vaginal births
„
0.15 – 1.7 per 100 vaginal births
„
0.2 – 6 per 1000 vaginal births

Vaginal exam rules out other causes of
difficulty:
„
Abdominal or thoracic enlargement of the infant
„
Locked or conjoined twins
„
Uterine constriction ring
8
Management
Anticipate and have experienced
team available
„
If occurs unexpectedly, call team immediately!
10
Empty bladder prior to start of the birth
11
Assist with maternal positioning that
maximizes pelvic size
„
Lying flat in bed compresses the sacrum

Intervention
Maneuvers
Unilateral shoulder dystocia is usually easily dealt with by
standard techniques.
(B. Harris, Shoulder dystocia. Clinical Obstetrics and Gynecology, 1984l 27:106)
Source: www.shoulderdystocia.com
20
Gentle pressure on the fetal vertex in a dorsal direction will
move the posterior fetal shoulder deeper into the maternal
pelvic hollow, usually resulting in easy delivery of the anterior
shoulder. Excessive angulation (>45 degrees) is to be avoided.
(Gabbe, Niebyl, and Simpson, Obstetrics: Normal and Problem Pregnancies, Churchill Livingstone, New York, 1986)
Source: www.shoulderdystocia.com
21
Increase relative pelvic space:
„
Fetal shoulder rotation to the oblique
22
Delivery may be facilitated by counterclockwise rotation of the
anterior shoulder to the more favorable oblique pelvic diameter, as
illustrated here, or, alternative, clockwise rotation of the posterior
shoulder. During these maneuvers, explusive efforts should be
stopped and the head is never grasped.
(Grabbe, Niebyl, and Simpson, obstetrics: Normal and Problem Pregnancies, Churchill Livingstone, New York, 1986.)

23
Altering pelvic angles
„
McRoberts maneuver
„
Hands-knees position (Gaskin maneuver)
24
McRoberts maneuver
Sharply flex the mother's thighs on to her abdomen. This will result in cephalic rotation
of the pelvis, releasing the shoulder.
FROM: ACOG Practice Patterns No7, October 1997
Source: 192.215.104.222/obgyn/cobra/cobra/ TEXT/PROTOCOL/shoul.htm
25
Sharp ventral rotation of both maternal hips brings the pelvic inlet
and outlet into a more vertical alignment, facilitating delivery of the
fetal shoulders.
(Gabbe, Niebyl, and Simpson, Obstetrics: Normal and Problem Pregnancies, Churchill Livingstone, New York, 1986)

28
„
Decreasing passenger shoulder diameter
„
Suprapubic pressure
„
Delivery of the posterior arm
„
Woods’ or Rubin’s screw maneuver
29
Moderate suprapubic pressure is often the only additional
maneuver necessary to disimpact the anterior fetal shoulder.
Stronger pressure can only be exerted by an assistant.
(Gabbe, Niebyl, and Simpson, Obstetrics: Normal and Problem Pregnancies, Churchhill Livingstone, New York, 1986.)

30
After proper suprapubic pressure, the fetal head will reassume a natural
relationship to the shoulders which are in the opposite oblique diameter
of the maternal pelvis.
(Gabbe, Niebyl, and Simpson, Obstetrics: Normal and Problem Pregnancies, Churchill Livingstone, New York, 1986)

31
This type of suprapubic pressure by an assistant may reduce the
impaction in some cases.

Best method for suprapubic pressure. This demonstrates
the use of the palm of the hand giving lateral pressure.

shoulder.

Wood's screw maneuver. The shoulders must be rotated utilizing
pressure on the scapula and clavicle. The head is never rotated.
(B. Harris, Shoulder dystocia. Clinical Obstetrics and Gynecology, 1984; 27:106)
Source: www.shoulderdystocia.com/ images_2.html
36
If less invasive maneuvers fail to affect this impaction, delivery should
be facilitated by manipulative delivery of the posterior arm by inserting
a hand into the posterior vagina and ventrally rotating the arm at the
shoulder with delivery over the perineum.

Posterior arm sweep
The fetal arm is swept forward along the chest keeping the arm flexed at the
elbow, the hand is grasped, and the arm extended along the side of the face.

Assisting with
Management of
Shoulder Dystocia
„
McRoberts Maneuver
„
Suprapubic Pressure
„
„
Ask which direction to apply pressure
Record sequence and timing of
events during birth
„
Accurately label fundal vs. suprapubic pressure in
documentation
40
„
Do not apply fundal pressure
„
Will impact the shoulders more firmly in the inlet
Exception:
„
Fundal pressure may be appropriate after the
shoulder has been disimpacted to help ease the
fetus under the symphysis
(Simpson, 1999)
41
The Hibbard maneuver. Release of the anterior shoulder is initiated by
firm pressure against the infant's jaw and neck in a posterior and upward
direction. An assistant is poised, ready to apply fundal pressure after
proper suprapubic pressure.
(Reprinted with permission from The American College of Obstetricians and Gynecologists. Obstetrics and Gynecology, 1969; 34 [3]:426)
Source: www.shoulderdystocia.com
42
As the anterior shoulder slips free, fundal pressure is applied, and
pressure against the neck is shifted slightly toward the rectum. Proper
suprapubic pressure is continued.
(Reprinted with permission from The American College of Obstetricians and Gynecologists. Obstetrics and Gynecology, 1969; 34 [3]:427)
Source: www.shoulderdystocia.com
43
Continued fundal and suprapubic pressure results in an upward-inward
rotation of the newly freed anterior shoulder and a further descent in a
position beneath the pubic symphysis.
(Reprinted with permission from the American College of Obstetricians and Gynecologists, Obstetrics and Gynecology, 1969; 34 [34]: 427.)

44
As a result of the previous maneuvers, the transverse diameter of the
shoulders is reduced. Lateral (upward) flexion of the head releases the
posterior shoulder into the hollow of the sacrum.
(Reprinted with permission from The American College of Obstetricians and Gynecologists, Obstetrics and Gynecology,1969; 34 [34]: 428.)

45
With both shoulders freed, delivery is accomplished without the
necessity of additional fundal pressure.

Nursing Implications
Intrapartum:
„
Identify antepartum risk factors
„
Identify and report deviations from normal labor
progress
„
Prepare for potential shoulder dystocia
„
„
„
„
Personnel
Supplies
Empty maternal bladder
Maternal positioning for birth
48
Birth:
„
Observe for “turtle sign” or obvious resistance of the anterior
shoulder
„
Document emergence of head
„
Call for help if not already there
„
Document any additional maneuvers attempted
„
Assist with maternal positioning
„ McRoberts
„ Suprapubic pressure (in direction indicated by provided)
„ Fundal pressure (only upon provider request)
„ All-fours
„
Support mother about bearing down when instructed by provider
49
If vaginal birth is not successful:
„
Prepare for immediate surgical birth
„
Continuously monitor fetus during the
Zavanelli maneuver until birth
50
A bilateral shoulder dystocia. The posterior shoulder is not in the
hollow of the pelvis. This presentation often requires a cephalic
replacement.

Diagram of the first part of the Zavanelli maneuver. If restitution has
occurred following expulsion of the head, as in this case, the head is
first manually returned to its prerestitution position, full extension in a
direct occipitoanterior position.

52
Diagram of second part of the Zavanelli maneuver. The head is
manually flexed recapitulating, in reverse, the birth of the head by
extension. Upward pressure to recapitulate expulsion, in reverse, was
not required in this instance.

Erbs Palsy Shoulder Dystocia Birth Injury
Center. Doctors deliver nearly five thousand
children a year who suffer from Brachial
Plexus Palsy (Erbs Palsy). In 90 percent of
Brachial Plexus Palsy cases, traumatic
stretching of the infant's plexus during birth
causes the palsy. Estimates suggest that
one to two out of every one thousand births
result in a brachial plexus injury. Of those,
one out of every ten represent an injury
serious enough to require some form of
treatment. If your child has suffered from this
type of injury, medical malpractice may be
involved. Contact us here to determine your
legal options.
