A Case of Abnormal Breathing

Case presentation

History

78 y/o female presenting s/p MVC. Pt was transported via helicopter after a dump truck collided into the passenger side of car; no airbags deployed as was in antique car. Patient was restrained driver with lap belt, and was driving ~20 mph. Per EMS, no LOC, HS and A&Ox3 throughout transport. Was given a total of 200mcg of fentanyl enroute. On evaluation, she is endorsing L scapula pain, denies other symptoms. Patient agitated secondary to pain. She was given 0.5mg Dilaudid in the trauma bay and wheeled to CT scan

  • Respiratory: CTAB, equal breath sounds​

  • Abdomen: no lacerations or external wounds, non tender to palpation​

  • Pelvis: stable pelvis, nontender to palpation, equal leg length​

  • Extremities: 5/5 strength and full ROM in Bilateral upper and lower extremities. 2+ peripheral pulses, warm and perfused. no pain with passive ROM or palpation​

  • Back: Abrasion and hematoma to L upper back, significant tenderness to palpation

  • Spine: no midline tenderness to palpation, no swelling, no step- offs, no lack of sensation in extremities​

Imaging

Significant findings on CT images: Negative for intracranial hemorrhage, cervical spinal fracture/subluxation. Nondisplaced fractures of anterior right first and second ribs. Fractures of left second through 11th ribs with some of these fractures comminuted and the more inferior left rib fractures markedly displaced. Small left hydropneumothorax.



Rib Fractures

  • Usually occur following a direct, blunt force to the ribs​

  • Result in splinting, short/shallow breaths, tachypnea, and hypoxia​

  • Most rib injuries due to trauma occur in a midaxillary or posteroaxillary location, where the rib is thinner​

  • Can occur along any rib however injuries to ribs 1, 2, and 3 are less common after trauma and suggest a higher-energy mechanism may have occurred

Diagnostics, Treatments, and Concerns

  • Diagnostics:

  • Treatment

  • multimodal approach to pain management incorporating opioid and nonopioid analgesics, neuraxial blockade, and regional anesthesia on an as needed basis ​

  • ketorolac may reduce the risk for pneumonia after rib fracture ​

  • low-dose ketamine infusion at a rate of failed to demonstrate improvement in pain scores or opioid requirements

  • Concerns.

Flail Chest

Definition

  • three or more adjacent ribs that are fractured at two points, creating a freely moving segment of the chest wall that results in paradoxical motion​

  • As the patient inhales, the intact chest wall moves outward, whereas the flail segment moves inward. As the patient exhales, the opposite occurs ​

  • --> ineffective ventilation because of increased dead space, decreased intrathoracic pressure, and increased oxygen demand from injured tissue

What about the O2%?

  • If the patient remains hypoxic while on supplemental O2 (NC/Venti/NRB), intubation and positive pressure ventilation should be considered and performed ​

  • However, continuous positive airway pressure is a potential alternative to endotracheal intubation in patients who require positive pressure ventilation but are appropriate based on clinical suspicion ​

  • Non-invasive CPAP with PCA led to lower mortality and a lower nosocomial infection rate, but similar oxygenation and length of ICU stay​
