Key Takeaways:

1. Recognize the four pillars of preterm labor management: transport to the appropriate facility, antibiotic administration, antenatal steroids, and magnesium for neuroprotection (before 32 weeks).
2. To prevent neonatal complications, maintain close monitoring during transport and prioritize fetal head control in the event of precipitous delivery.
3. Understanding preterm labor risk factors—such as infection, smoking, limited access to care, and history of preterm births—can help guide critical care decisions.
4. Tocolytic options like calcium channel blockers or beta sympathomimetics are helpful for delaying delivery short-term but require careful consideration of contraindications.
5. The preterm infant’s immediate needs at birth include delayed cord clamping and potential neonatal resuscitation, underscoring the importance of being prepared for rapid response.

Join us for another captivating episode of The FlightBridgeED MDCAST as Dr. Michael Lauria explores trauma medicine's most critical and evolving skill: the finger thoracostomy.

TAKEAWAYS

• Understanding the difference between tension pneumothorax and regular pneumothorax is crucial in trauma care.
• Ultrasound can be a valuable tool for identifying pneumothorax in trauma patients.
• The choice between needle decompression and finger thoracostomy depends on the clinical scenario and the availability of a sterile environment.
• Proper identification of landmarks is essential for successful finger thoracostomy.
• Chest tube placement may be appropriate in a controlled environment with access to sterile equipment. Finger thoracostomy is a crucial intervention in the pre-hospital setting for trauma patients with chest injuries and hemodynamic compromise.
• Training and education for nurse medics in performing finger thoracostomy are essential for safe and effective implementation.
• The safety and efficacy of finger thoracostomy in the pre-hospital setting make it a valuable skill for managing trauma patients in critical care transport.
• The decision to perform a finger thoracostomy should be guided by the presence of hemodynamic compromise and the need for timely intervention in trauma patients with chest injuries.
• The use of finger thoracostomy as an empiric decompression in polytrauma patients with suspected tension pneumothorax is reasonable and can be performed in parallel with other resuscitative measures.

Welcome to another essential episode of the FlightBridgeED Podcast: MDCAST, where we dive deep into the complexities of critical care and continue our high-risk OB transport conversation.

Key Takeaways:

1. Pathophysiology of Preeclampsia: This condition often arises from placental abnormalities that lead to widespread vascular issues, impacting both the mother and fetus.
2. Magnesium Sulfate in Management: Magnesium sulfate is vital for preventing eclampsia and should be monitored for toxicity, especially in patients with reduced kidney function.
3. Identification of Hypertensive Disorders: A blood pressure reading of 160/110 mmHg or greater post-20 weeks' gestation is a significant indicator of hypertensive disorders, warranting immediate medical attention.

In this episode of our series on respiratory critical care called Every Breath They Take, Dr. Lauria is joined by EM/Critical Care and Flight Physician Brittney Bernardoni as they discuss how to grapple with optimizing lung protective ventilation in ARDS.  

Lung protective ventilation at 6 cc/kg and maintaining plateau pressures of less than 30 cmH2O have been the cornerstones of invasive respiratory support since the findings of the ARMA trial in 2000.  In recent years, some interesting new developments have resulted in changes and improvements in lung protective ventilation strategies.  With a particular focus on ventilator "jiu-jitsu," this episode explores the intricate adjustments required to optimize patient care during ARDS management. From ventilator modes and plateau pressure to the impact of PEEP, FiO2, and mechanical power, this episode equips listeners with actionable knowledge for mastering the art of ventilation. Whether in the field or the ICU, the nuanced approaches discussed in this episode will enhance your understanding of optimizing respiratory support in critical patients.

Takeaways
• Early care in managing respiratory failure in the transport environment is crucial and can significantly impact patient outcomes.
• Lung protective ventilation with low tidal volumes is the foundation of ARDS management.
• The choice of ventilation mode (volume control or pressure control) depends on the clinician's comfort and ability to titrate the settings, but neither has proved superior.
• Permissive hypercapnia is generally well-tolerated in ARDS patients if the pH exceeds 7.15-7.20.
• The initial PEEP setting should be at least eight -  several strategies can be used to guide titration.
• High FiO2 levels can be detrimental to ischemic organs, alveolar patency, and the lung tissue itself.  Aiming for a FiO2 of less than or equal to 60% is important.
• Set, check, and change parameters to ensure optimal ventilation!
• Driving pressure may be an important factor in patient outcomes.
• Mean airway pressure and inspiratory time can improve oxygenation and minimize lung damage

In this episode of the FlightBridgeED Podcast, part of our "Every Breath They Take" series on respiratory critical care, Dr. Michael Lauria explores whether we truly protect the lungs during mechanical ventilation. While the best evidence suggests keeping tidal volumes at 6 cc/kg and plateau pressures below 30 cm H2O, is that enough? ARDS is a complex lung pathology, and as we unravel its intricacies, there may be more to consider.

Join us as we explore the popular concept of driving pressure and introduce the emerging idea of mechanical power. While plateau pressure remains the gold standard, these additional metrics may provide further guidance for adjusting ventilation strategies and minimizing ventilator-induced lung injury, especially in critical care transport settings. Whether you're new to the field or a seasoned professional, this episode offers valuable insights into advanced respiratory management.

TAKEAWAYS

• Mechanical ventilation is a double-edged sword. It can maintain oxygenation and ventilation but can also damage the lungs.
• Lung protective ventilation prevents ventilator-induced lung injury, especially in acute respiratory distress syndrome (ARDS).
• Maintaining a plateau pressure below 30 cmH2O is an essential goal in lung protective ventilation.
• Driving pressure, the difference between plateau pressure and PEEP, is a surrogate for transpulmonary pressure and may be a useful parameter to consider in lung protective ventilation.
• Keeping driving pressure < 15 cmH2O may be beneficial. 
• Driving pressure might be helpful in titrating peep and optimizing lung recruitment, as well as in identifying patients who may benefit from smaller tidal volumes, even if the plateau pressure is below 30.
• Mechanical power, which represents the energy delivered to the lung over time, is a newer concept that requires further research to determine its role in lung protective ventilation.
• Optimizing the ventilatory and inspiratory flow rates (in addition to peep, plateau pressure, and tidal volume) may help reduce mechanical power below 17-22 J/min.
