Birth shoulder distocia - Nursing Case Study

Pathophysiology

• Primary mechanism: Shoulder dystocia occurs when the fetal anterior shoulder becomes lodged behind the maternal pubic symphysis after the delivery of the head, often due to disproportionate fetal size relative to the maternal pelvis, known as cephalopelvic disproportion.

• Secondary mechanism: Excessive fetal size (macrosomia) or abnormal fetal positioning (e.g., transverse shoulder presentation) can exacerbate the risk of shoulder impaction, as these conditions increase the likelihood of the shoulder failing to navigate through the pelvic inlet.

• Key complication: If not resolved promptly, shoulder dystocia can lead to brachial plexus injury due to excessive traction on the fetal head and neck during delivery, resulting in potential neonatal morbidity, including Erb's palsy.

Section 1

As the delivery team worked to address the shoulder dystocia, the obstetrician implemented the McRoberts maneuver, instructing the nursing staff to assist in hyperflexing the maternal hips to increase the pelvic outlet. Despite these efforts, the fetal heart rate began to show signs of distress, with a deceleration pattern to 90 bpm, suggesting potential hypoxia. The mother, already exhibiting signs of maternal fatigue and anxiety, was encouraged to remain as calm as possible while the team strategized further interventions.

The decision was made to perform a suprapubic pressure maneuver in an attempt to dislodge the fetal shoulder. During this intervention, the nurse closely monitored the mother's vital signs, noting an increase in blood pressure to 150/95 mmHg and respiratory rate climbing to 28 breaths per minute, indicating heightened maternal stress. The fetal heart rate briefly improved to 110 bpm, yet variability remained minimal. The mother also reported tingling sensations in her hands, potentially due to hyperventilation or anxiety, necessitating supportive coaching to regulate her breathing.

As the obstetrician prepared for a potential episiotomy to facilitate delivery, the team remained vigilant for any signs of maternal or fetal compromise. The nursing staff prepared for possible neonatal resuscitation should the newborn face respiratory challenges immediately after birth. The overarching goal remained to deliver the baby safely while minimizing the risk of brachial plexus injury and ensuring maternal stability. This situation required the nursing team to use their clinical reasoning skills to anticipate and manage developing complications effectively, keeping both maternal and neonatal outcomes at the forefront of their care planning.

Section 2

As the delivery team continued to manage the shoulder dystocia, the obstetrician proceeded with the episiotomy, and the team noted a significant change in the patient's status. The fetal heart rate, which had briefly stabilized at 110 bpm, began to drop again, this time to 80 bpm, signaling worsening fetal distress. The mother’s blood pressure remained elevated at 155/98 mmHg, and her respiratory rate increased further to 32 breaths per minute, correlating with anxiety and possible pain escalation. The tingling in her hands persisted, despite attempts to guide her through breathing exercises. The nurse, recognizing the signs of maternal hyperventilation and the potential for respiratory alkalosis, encouraged deeper, slower breaths and considered the administration of supplemental oxygen to optimize both maternal and fetal oxygenation.

Meanwhile, the obstetrician, aware of the urgency, employed additional maneuvers such as the Rubin and Woods screw maneuver to relieve the dystocia. The team was vigilant in their observation, noting any maternal or fetal compromise that could necessitate a shift to an immediate cesarean section if these efforts failed. The nursing staff remained prepared for neonatal resuscitation, ensuring that equipment such as an infant warmer, bag-mask ventilation, and intubation supplies were readily available. They also prepared to administer medications like epinephrine or naloxone if required, depending on the newborn's status post-delivery.

Throughout this critical juncture, the nursing team was tasked with closely monitoring the maternal vital signs and fetal heart patterns, documenting any changes meticulously. They encouraged maternal cooperation and focused on effective communication to ensure the mother understood the gravity of the situation without exacerbating her anxiety. As the obstetrician prepared for a last-resort cesarean section, the team reassessed their interventions, considering the balance between the urgency of delivery and the potential risks involved with each maneuver. The situation demanded careful prioritization and rapid decision-making to optimize both maternal and neonatal outcomes.

Section 3

As the obstetrician continued to employ maneuvers to alleviate the shoulder dystocia, the team observed a change in the mother's status that warranted immediate attention. Her blood pressure began to rise further, reaching 165/100 mmHg, indicating a possible progression towards preeclampsia. Simultaneously, the fetal heart rate continued to decelerate, dropping to a concerning 70 bpm. The nurse quickly alerted the obstetrician to these developments, emphasizing the need for expedited delivery to prevent further fetal compromise. The mother's respiratory rate remained elevated at 30 breaths per minute, with persistent tingling in her extremities despite supplemental oxygen therapy. This clinical picture suggested the possibility of maternal exhaustion and the need for additional support.

Given the compounded stressors on both the mother and fetus, the obstetrician decided to proceed with an emergency cesarean section. The team swiftly prepared for the transition, ensuring the operating room was ready and that all necessary personnel were in place. The anesthesiologist was briefed on the situation and worked efficiently to administer spinal anesthesia, allowing for rapid surgical intervention. Meanwhile, the nursing staff maintained continuous monitoring of maternal vital signs and fetal heart patterns, documenting each change meticulously to provide a comprehensive overview of the ongoing situation. The team also communicated effectively with the mother, providing reassurance and clear explanations of the procedure to help manage her anxiety.

As the surgical team initiated the cesarean section, the nurse observed a significant decrease in maternal anxiety levels, likely due to the sense of relief that action was being taken. The mother's blood pressure began to stabilize at 150/95 mmHg, and her respiratory rate decreased to 28 breaths per minute, indicating a positive response to both the intervention and supportive care measures. The fetal heart rate, however, remained low, underscoring the critical need for expedited delivery to prevent potential neonatal complications. Throughout this intense period, the healthcare team demonstrated astute clinical reasoning, balancing the urgency of the situation with the need for careful monitoring and intervention, setting the stage for the next steps in managing the patient's care.

Section 4

As the cesarean section progressed, the surgical team successfully delivered the baby, who presented with cyanosis and poor muscle tone, indicative of a moderate neonatal respiratory distress. The Apgar score at one minute was 4, prompting immediate neonatal resuscitation efforts. The pediatric team quickly initiated positive pressure ventilation and administered supplemental oxygen. Within minutes, the baby’s color and tone improved, and the Apgar score increased to 7 at five minutes, suggesting a positive response to the interventions. Meanwhile, the obstetrician completed the delivery of the placenta and began to close the surgical site, while the nursing team continued to monitor the mother closely.

Postoperatively, the mother was transferred to the recovery room, where her vital signs were reassessed. Her blood pressure was noted to be 145/90 mmHg, and her respiratory rate had decreased to 24 breaths per minute. Despite these improvements, laboratory results soon revealed that her platelet count had dropped to 95,000/mm³, raising concerns for thrombocytopenia associated with preeclampsia. This necessitated ongoing monitoring and the consideration of magnesium sulfate therapy to prevent seizure activity, given the preeclampsia diagnosis.

The situation demanded careful clinical reasoning by the healthcare team to balance the management of preeclampsia with the need for ensuring optimal recovery from the cesarean section. Discussions were initiated regarding the need for a hematology consult to evaluate the thrombocytopenia further and to determine the best course of action for ongoing maternal care. The team also focused on supporting the mother emotionally, providing her with updates on both her condition and her newborn's progress in the neonatal intensive care unit. This multifaceted approach highlighted the complexity of care required in such scenarios, underscoring the importance of interdisciplinary collaboration in achieving positive outcomes for both mother and child.

Section 5

As the mother settled into the recovery phase, the nursing team conducted an initial assessment to ensure her stability. Despite the administration of magnesium sulfate, she began to exhibit signs of increasing respiratory distress, characterized by shallow breathing and an oxygen saturation level that had fallen to 88%. These findings were concerning, especially in the context of her existing hypertensive state and potential fluid overload from the surgical procedure. Her heart rate had also increased to 110 beats per minute, prompting further evaluation for possible pulmonary complications.

The clinical team immediately responded by adjusting her oxygen supplementation and elevating the head of her bed to facilitate easier breathing. In light of these developments, a chest X-ray was ordered to assess for any underlying pulmonary edema or other respiratory complications. Concurrently, the team reviewed her fluid balance, noting a positive fluid status that raised suspicions of pulmonary congestion. The decision was made to initiate diuretics cautiously, aiming to reduce the fluid overload while closely monitoring her response to this intervention.

These changes in her status required the healthcare team to refine their clinical reasoning, balancing the management of her preeclampsia with the emergent respiratory concerns. The interdisciplinary team, including specialists in obstetrics, internal medicine, and respiratory therapy, convened to optimize her care plan, emphasizing the need for vigilant monitoring and timely interventions. This collaborative approach was vital in addressing the new complications, ensuring both the mother’s safety and her progression towards recovery.
