Shoulder Dystocia Nursing Interventions and Risk Management Strategies© Mary Wright, MSN, RNC, CNS Instructor/Maternity Nursing College of Nursing Health Sciences Center University of New Mexico 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) 2 Source: http://www.flash.net/~rustyj/SD.gif 3 Incidence .23% to 2.09% of all vaginal births 0.15 – 1.7 per 100 vaginal births 0.2 – 6 per 1000 vaginal births Why the range? Variation in definitions and incomplete documentation (Simpson, 1999) 4 Recognition of Shoulder Dystocia Recoil of the head back against the perineum caused by impaction of the anterior shoulder behind the symphysis pubis 6 “Turtle sign” http://www.shoulderdystociainfo.com/resolvedwithoutfetal.htm - retrieved on 7/19/05 7 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 12 Risk Factors for Shoulder Dystocia Macrosomia Maternal diabetes Postdates pregnancy Slow labor progress with adequate contractions Slow descent of presenting part in labor History of previous shoulder dystocia “Tight fit” 14 Maternal Complications Episiotomy Extended Lacerations Hematomas Uterine atony Hemorhage Bladder Injury Rectal Injury 16 Fetal Complications Fractures of clavicle or humerus Brachial plexus injury or other spinal nerve damage Asphyxia Erb’s palsy Mental retardation Death 18 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.

Source: www.shoulderdystocia.com 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.

Stronger pressure can only be exerted by an assistant. (Gabbe, Niebyl, and Simpson, Obstetrics: Normal and Problem Pregnancies, Churchhill Livingstone, New York, 1986.) Source: www.shoulderdystocia.com 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) Source: www.shoulderdystocia.com/ images_2.html 31 This type of suprapubic pressure by an assistant may reduce the impaction in some cases. (B. Harris, Shoulder dystocia. Clinical Obstetrics and Gynecology, 1984; 27:106) Source: www.shoulderdystocia.com/ images_2.html 32 Best method for suprapubic pressure. This demonstrates the use of the palm of the hand giving lateral pressure. (C.

FROM: ACOG Practice Patterns No7, October 1997 Source: 192.215.104.222/obgyn/cobra/cobra/ TEXT/PROTOCOL/shoul.htm 35 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.

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.

Source: www.shoulderdystocia.com 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.

The posterior shoulder is not in the hollow of the pelvis. This presentation often requires a cephalic replacement. (C.Pauerstein [ed.], Clinical Obstetrics, Churchill Livingstone, New York, 1987.)

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.

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. (E.C. Sandberg.

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.
