Shoulder Dystocia Maneuvers: Obstetric Emergency Step-by-Step

This comprehensive section covers the assessment and management of neonatal trauma during delivery. Shoulder dystocia occurs when only the baby's head emerges, requiring manual maneuvers or instruments for safe extraction. The Moro reflex, characterized by arm extension, is a normal neurological response used to differentiate between clavicle fractures and brachial plexus injuries. Clavicle fractures are diagnosed through physical examination (sign of the key) and radiographic imaging, with treatment involving immobilization using splints or bandages. Brachial plexus injuries are differentiated by motor function patterns: lower plexus injuries show hand movement without arm movement, while upper plexus injuries show arm movement without hand movement. Both conditions require immobilization with the arm in 90 degrees of flexion and external rotation.

Approximately 95% of shoulder dystocia cases result in no injury to the newborn. Among the 5% with complications, transient brachial plexus injury is most common (15% of cases), followed by clavicular and humerus fractures. Hypoxic-ischemic encephalopathy (brain damage from oxygen deprivation) is rare (0-0.35%) but can cause severe disabilities. Maternal complications include hemorrhage (11%) and fourth-degree tears (4%). Gestational diabetes increases risk by widening baby shoulders, though most cases occur without this condition.

Shoulder dystocia is an obstetric emergency characterized by failure to deliver fetal shoulders after the head is delivered, diagnosed when the head-to-body delivery ratio exceeds 1 minute (turtle sign). Risk factors include maternal diabetes, fetal macrosomia, obesity, and previous shoulder dystocia. Management follows a stepwise approach: first-line maneuvers include McRoberts maneuver (maternal hip flexion) with suprapubic pressure; second-line maneuvers include Rubin's maneuver, Woods screw maneuver, and posterior arm delivery; heroic measures as last resort include intentional clavicular fracture, Zavanelli maneuver, abdominal rescue, and symphysiotomy. Complications include brachial plexus injury (Erb's palsy), clavicular/humeral fractures, hypoxic brain injury, and maternal trauma.

Birth injuries range from superficial cuts to serious conditions. Shoulder dystocia: shoulder impaction in pubic symphysis (1 in 150 vaginal births). Risk factors: gestational diabetes, previous dystocia, macrosomia, induction, BMI >30, prolonged labor, instrumental delivery. Complications: clavicle/humerus fractures, brachial plexus injury, hypoxia (baby); third/fourth-degree tears, postpartum hemorrhage (mother). Management: McRoberts maneuver, suprapubic pressure. Brachial plexus injury: C5-T1 nerves under shoulder. Types: neuropraxia (stretch, most common, recovers 3-6 months), rupture (surgical repair), avulsion (nerve transfer). Complications: Erb's palsy (C5-C6, waiter's tip), Klumpke's palsy (C8-T1, claw hand), Horner's syndrome (T1-T2). Scalp anatomy: 5 layers. Hematomas: caput (skin-subgaleal, improves in days), cephalohematoma (subperiosteal, presents in hours-days), subgaleal (life-threatening, crosses suture lines, hypovolemic shock risk).

Shoulder dystocia occurs when the shoulder lodges behind the pubic bone during labor. Risk factors: fetal macrosomia (from gestational diabetes) and prolonged labor. Complications: fetal hypoxia, cerebral palsy, Erb's palsy (brachial plexus injury), perineal tears, postpartum hemorrhage, and fetal fractures (clavicle/humerus). Erb's palsy (C5-C6 injury, 'waiter's tip') features: loss of sensation, paralysis, atrophy of deltoid/biceps/brachialis, arm hanging internally rotated with forearm extended and pronated. This condition is highly examinable as it crosses multiple medical specialties.

Postpartum hemorrhage is classified as Early (within 24 hours, most commonly uterine atony) or Late (24 hours to 6 weeks, often retained fragments). Management depends on cause: For uterine atony, massage fundus and administer oxytocin. For trauma (lacerations), check perineum; first/second-degree can be sutured by nurses, third/fourth-degree require physician referral. For tissue problems (retained fragments after 24 hours), evacuation is needed. For thrombin problems, coagulation workup is required.

This segment covers two critical obstetric topics: (1) Methylergonovine contraindications - it is contraindicated in hypertensive patients and has been removed from ACOG guidelines as a third-line PPH treatment, (2) Perineal laceration classification - first-degree involves vaginal mucosa, second-degree adds perineal muscles, third-degree includes anal sphincter, and fourth-degree involves rectum. Midline incisions are avoided to prevent rectal involvement; mediolateral incisions are preferred. The instructor emphasizes understanding current ACOG guidelines for PPH management.

This section covers PPH management, postpartum complications, third stage management, and VBAC. PPH management protocol: uterine massage, oxytocin (20-40 IU), misoprostol, carboprost (up to 8 doses), uterine balloon tamponade (Bakri, 500ml), external aortic compression, uterine artery embolization, or compression sutures (B-Lynch). Tranexamic acid (1g IV) is added per WHO recommendations. Uterine rupture diagnosis: fetal parts palpable superficially, loss of station, fetal bradycardia, free fluid in peritoneum. Immediate laparotomy is required. Postpartum blues is mild psychiatric illness within first 10 days. Puerperal pyrexia is temperature >100.4°F within first 24 hours. Uterine involution: day 1 at umbilicus, day 2 one finger breadth below. Pelvic types: gynecoid (most favorable), platypelloid (transverse diameter larger), android (prominent ischial spines, deep transverse arrest common), anthropoid (AP diameter larger, persistent occiput posterior common). Third stage management: most important is injection uterotonic (oxytocin 10 IU IM within 1 minute). Delayed cord clamping is 1-3 minutes. Modified Zavanelli maneuver is done at crowning to prevent perineal tears. Montevideo units: first stage 120-150, second/third stage 300. Midpelvis contraction: interspinous diameter <8 cm. Inlet contraction: obstetric conjugate <10 cm. Outlet contraction: intertuberous diameter <8 cm. Vaginal birth after cesarean (VBAC) is tried only after lower segment cesarean (not classical), maximum 2 previous sections. Preferred episiotomy is mediolateral (60° angle). Vaginal pH: before puberty 6-7.5, reproductive age 4-4.5, pregnancy 3.5-4. Bacterial vaginosis treatment: metronidazole or clindamycin. PCOS diagnosis: infrequent cycles, hirsutism, increased testosterone (FSH normal/decreased, LH increased). Laparoscopic ovarian drilling is a treatment option.

Postpartum hemorrhage (PPH) is a leading cause of maternal mortality requiring immediate, systematic management based on its underlying cause. The management protocol begins with essential emergency interventions including calling for medical assistance, establishing two large-bore IV lines for fluid resuscitation and blood transfusion, performing blood investigations (bleeding time, clotting profile, fibrinogen, blood grouping), and catheterizing the bladder to monitor urine output and facilitate uterine contraction. For third-stage PPH where the placenta is not separated, uterine fundal massage is performed, followed by oxytocin infusion and controlled cord traction if the placenta separates; if not, manual removal under general anesthesia is required. For true PPH caused by atonic uterus, a stepwise pharmacological approach is employed starting with oxytocin IV infusion, progressing to methergine IM/IV, then misoprostol rectally (800-1000 mcg), and finally carboprost IM (250 mcg, max 8 doses). If uterotonic drugs fail, bimanual compression is performed, followed by uterine tamponade using Bakri balloons or condom catheters. Surgical options include uterine compression sutures (B-Lynch technique), stepwise devascularization (bilateral uterine artery ligation, then bilateral ovarian artery ligation, then bilateral anterior division of internal iliac artery ligation), and hysterectomy as the last resort. For traumatic PPH, exploration under general anesthesia with suturing of tears is performed. For secondary PPH occurring after 24 hours, exploration under general anesthesia is required to remove retained tissues which interfere with effective uterine contractions.

Postpartum hemorrhage management follows a systematic approach prioritizing patient safety and rapid intervention. The first action when a patient experiences active bleeding is to assist them back to bed for safety before assessment. Methergine is the drug of choice; if unavailable, misoprostol serves as an alternative. Uterine atony (boggy fundus) is the primary cause. Clinical findings include boggy fundus unresponsive to massage, hematoma formation with bulging perineal skin, and rising fundal height. Detection methods include weighing perineal pads and monitoring hemoglobin/hematocrit levels.

Emergency obstetric protocols should be laminated and available in labor rooms, OPD, wards, and triage areas. Examples include shoulder dystocia protocols specifying personnel to call, fetal viability, cervical dilation, and immediate maneuvers; eclampsia protocols specifying left lateral position and medications; and postpartum hemorrhage protocols outlining resuscitation steps and senior notification. Standardized documentation forms enable rapid emergency recording, serve medical-legal purposes, and support quality improvement. Surgical safety checklists should be pre-printed and followed before anesthesia induction, skin incision, during procedures, and post-completion, serving both safety and legal documentation needs.

Avoid making clinical assumptions that coders cannot translate; instead document actual diagnoses. For postpartum hemorrhage, document 'postpartum hemorrhage with estimated blood loss greater than 500 mL' to capture both diagnosis and quantifiable data. Induction of labor requires clear documentation of the indication using 'due to' or 'secondary to' (e.g., 'induction of labor due to development of preeclampsia'). Distinguish between pregnancy-induced hypertension (newly developed) versus pre-existing hypertension exacerbated by pregnancy, and between gestational diabetes versus type 2 diabetes exacerbated by pregnancy. 'Failure to progress' alone cannot be coded and requires specification of labor stage (first or second stage); alternative terms include 'uterine inertia' and 'obstructed labor.' Detailed documentation of delivery interventions including specific instruments used (Simpson's forceps, Kielland's forceps, Wrigley's forceps) and rationales for clinical decisions is crucial for coding and medical-legal purposes. Postpartum hemorrhage documentation requires volumes over 500 mL classified as hemorrhage, with associated conditions and management interventions linked to the hemorrhage diagnosis.

Failing to create correct nursing clinical records constitutes a legal, ethical, and professional violation. Quality documentation must be brief, concise, precise, and congruent with reality. The nursing process has evolved from 5 to 6 stages, with planning now separated into planning for outcomes and planning for interventions. All clinical records must include all stages, standardized assessment methods, interdependent problems using PES format, NANDA-aligned diagnoses, expected outcomes, and interventions. In obstetric emergencies, nurses must document comprehensive assessments following the ABCDE approach: Airway/Ventilation, Circulation, Neurological status, and Exposure. Documentation should include triage color assigned and justify emergency code activation. All data must be interpreted and documented with descriptive terms rather than raw numbers.

Medico-legal documentation provides official records of injuries and deaths, and timelines must be verified through multiple sources. The video shows that Brian Laresma was brought to the hospital at 7:00 PM and examined by Dr. Emerson C. Lim. However, the Provincial Director stated he did not know when Brian Laresma was brought to the hospital, raising questions about the chain of command and accountability. This demonstrates the importance of verifying timelines through multiple sources and maintaining proper documentation.

Perinatal emergency nursing care encompasses: (1) Role in emergency management including rapid assessment, vital sign monitoring, and resource preparation, (2) Legal and ethical considerations including patient rights, informed consent, and confidentiality, (3) Priority nursing diagnoses including risk for injury, ineffective tissue perfusion, and impaired gas exchange, (4) Nursing interventions including oxygen therapy, fluid management, and family support, and (5) Documentation requirements for legal protection and quality improvement. Documentation must be clear, comprehensive, timely, and accurate. Key elements include patient information, assessments, interventions, medications, and outcomes. Proper documentation supports legal defense, facilitates handoffs, enables quality audits, and contributes to research databases.

The HELPERR mnemonic guides shoulder dystocia management: H (Help), E (Evaluate), L (Legs/McRoberts), P (Position), E (Episiotomy), R (Ruben's), R (Remove posterior arm). McRoberts maneuver (90% effective) involves maximal hip flexion. Ruben's maneuver rotates the anterior shoulder by applying pressure on its posterior surface. Woods screw maneuver converts the posterior shoulder to anterior position by pushing it 180 degrees. Posterior arm extraction reduces shoulder diameter by 20% by pulling the arm along the thoracic cage. Maternal position change to knee-elbow position shifts shoulders to oblique diameter.

Shoulder dystocia is an obstetric emergency requiring immediate, coordinated action using the HELPERR protocol: H (Call for help), E (Evaluate and explain), L (Make McRoberts position), E (Apply suprapubic pressure), R (Apply gentle traction), and R (Perform internal maneuvers including Rubin's, Wood's screw, and Reverse Wood's screw maneuvers). The management sequence should be performed systematically with each maneuver attempted for 30 seconds before proceeding to the next, and the obstetrician must document all steps and debrief the team after delivery.

Performing interdisciplinary simulation drills is essential for hemorrhage preparedness because hands-on practice leads to greater retention than lectures alone. Drills should be conducted at different times of day since hemorrhages can occur anytime, revealing operational inefficiencies that exist only outside normal hours. All healthcare team members including anesthesiologists, nurses, physicians, and ancillary staff should participate to identify system gaps.

The HELPERR mnemonic (Help, Evaluate, Legs, Pressure, Enter, Remove, Roll) provides a systematic approach for managing shoulder dystocia during childbirth, where healthcare providers call for help, evaluate the situation, perform McRoberts' maneuver with suprapubic pressure, enter with internal rotation maneuvers (Rubin and Woods), remove the posterior arm to narrow shoulder diameter, and roll the mother to all fours to utilize gravity for delivery.

The HELPERR mnemonic guides shoulder dystocia management: H - Call for help immediately; E - Evaluate the situation; L - Leg maneuver (McRoberts maneuver: flex hips and abduct legs to increase pelvic space); E - Enter the rotational maneuvers (suprapubic pressure and arm delivery); R - Remove posterior arm; R - Roll to hands and knees and repeat maneuvers. Each maneuver takes approximately 1 minute, with 10-20 seconds between steps. If all maneuvers fail, consider surgical options including symphysiotomy, clavicularotomy, or emergency cesarean section.
