EMS Anatomy & Physiology - Curvature of the Spine

 

EMS Providers should have a basic understanding of skeletal issues like kyphosis, lordosis, and scoliosis, as well as related problems, to provide appropriate care for patients.

Here are a few key points:

Identification: EMS providers should be able to identify these skeletal issues through visual observation and patient history.

1. Kyphosis: Kyphosis refers to an excessive forward curvature of the upper spine, leading to a rounded or hunched posture. It can be caused by several factors, including poor posture, osteoporosis, spinal fractures, or certain medical conditions. EMS providers should be aware of the potential for compromised breathing and mobility in patients with severe kyphosis.

2. Lordosis: Lordosis is an excessive inward curvature of the lower spine, commonly known as swayback. It can be caused by various factors such as obesity, pregnancy, muscle imbalances, or certain medical conditions. EMS providers should be cautious of potential back pain and difficulty maintaining a supine position in patients with pronounced lordosis.

3. Scoliosis: Scoliosis is a medical condition characterized by an abnormal sideways curvature of the spine. This condition can manifest in various degrees of severity and is often idiopathic, meaning the cause is unknown. However, it can also result from congenital factors, neuromuscular conditions, or trauma.

Symptoms: Be aware of common symptoms associated with these conditions, such as pain, limited range of motion, and respiratory difficulties, which can occur due to the abnormal spinal curvature.

Assessment: Conduct a thorough physical assessment to evaluate the severity of the condition, including the degree of curvature, associated deformities, and neurological symptoms.

Stabilization: When immobilizing the patient, EMS providers should consider the unique spinal curvature and use appropriate spinal immobilization techniques to ensure patient comfort and safety. This may involve padding and positioning devices to accommodate the curvature.

Transport: Ensure safe and appropriate transport of patients with these conditions. They may require specialized equipment, such as scoop stretchers or vacuum mattresses, to maintain proper spinal alignment.

Communication: Effective communication with the patient is crucial. Ensure the patient is comfortable and aware of the care being provided. Also, obtain a medical history to determine if there are underlying causes or exacerbating factors related to the skeletal issue.

Related Problems: Understand that these skeletal issues can lead to other medical problems. For example, kyphosis and lordosis can cause respiratory issues by reducing lung capacity, so monitor the patient's respiratory status carefully. They might also be at a higher risk of spinal fractures or other spinal cord injuries. Additionally, scoliosis can sometimes be associated with cardiac and pulmonary complications, which should be considered during patient assessment.

Medication and Pain Management: Be aware of any medications the patient is taking, as well as their potential side effects and interactions. Patients with these conditions may require pain management during transport, so be prepared to administer appropriate pain relief under medical direction.

Special Considerations: Individuals with skeletal issues may require special handling, including assistance with transfers, lifting, or moving the patient. Consider the patient's comfort and any potential complications that may arise from moving them.

Collaboration: Work closely with other healthcare providers, including receiving facilities and specialists, to ensure a seamless transition of care and to address any specific needs related to the patient's condition.

Remember that each patient's needs may vary, so adapt your care accordingly. Additionally, staying updated on current guidelines and protocols for spinal immobilization and care of patients with skeletal issues is essential to providing appropriate care in the field.

EMS Eponymous Condition - Cushing's Triad

Cushing's Triad is named after Dr. Harvey Cushing, an American neurosurgeon who made significant contributions to the field of neurosurgery.

Dr. Cushing described a set of clinical signs and symptoms associated with increased intracranial pressure in his work "Intracranial Tumours: Notes upon a Series of Two Thousand Verified Cases with Surgical Mortality Percentages Pertaining Thereto."

This work was published in 1901, and it was one of the earliest descriptions of the physiological changes associated with intracranial pressure.

Recognizing Cushing's Triad is crucial for EMS Providers, as it is suggestive of a potentially life-threatening situation due to various adverse conditions, including head injuries and brain pathologies. As such, the need for urgent medical intervention is paramount.

Cushing's Triad consists of the following three key signs:

Hypertension (High Blood Pressure):

A significant increase in systolic blood pressure is a common feature of Cushing's Triad. This is a response to the body's attempt to maintain cerebral perfusion (blood flow to the brain) in the face of elevated intracranial pressure.

Bradycardia (Slow Heart Rate):

Cushing's Triad often includes a slow heart rate (bradycardia), particularly as a result of increased ICP. This is a compensatory mechanism intended to decrease the heart's pumping strength, reducing blood flow to the brain and thereby minimizing the risk of further brain damage.

Irregular or Abnormal Respiratory Patterns:

The third component of Cushing's Triad is abnormal breathing patterns, typically characterized by irregular or irregularly deep respirations. This is often referred to as "agonal" or "Cheyne-Stokes" breathing.

These respiratory changes are a response to the brain's attempt to restore oxygen levels and eliminate excess carbon dioxide, which can occur due to impaired blood flow or brainstem compression.

Recognizing Cushing's Triad in a patient is a critical finding for EMS providers, as it may indicate an impending brain herniation, which is a life-threatening condition.

Patients displaying Cushing's Triad should be managed promptly and transported to a specialized facility for further evaluation and potential surgical intervention.

Here are some key points for EMS Providers:

Perform a detailed neurological assessment, including monitoring vital signs, level of consciousness, and pupillary response.

Administer supplemental oxygen to ensure adequate oxygenation.

Maintain cervical spine immobilization to prevent further spinal cord injury, if applicable.

Communicate with the receiving medical facility to ensure they are prepared for the patient's arrival and can provide neurosurgical expertise if necessary.

Avoid hyperventilation, as it may worsen cerebral ischemia.

Cushing's Triad is a critical clinical finding that requires immediate attention and transport to a higher level of care.

EMS providers should follow their local protocols and seek medical direction when managing patients with Cushing's Triad.

EMS Trauma Emergencies - Thoracic Injuries


The "Deadly Dozen" is a term used in emergency medicine and prehospital care to refer to a list of twelve potentially life-threatening chest injuries. 

EMS Providers need to be familiar with these injuries because prompt recognition and appropriate management are crucial for the survival and well-being of the patient. 

Here are the Deadly Dozen Chest Injuries and why they are important for EMS providers to know about:

1. Lung Contusion: A lung contusion is a bruising of lung tissue caused by chest trauma, leading to impaired gas exchange and respiratory distress. Monitoring for signs of respiratory compromise is crucial.

2. Tracheobronchial Injury: Trauma to the trachea or bronchi can lead to airway compromise and respiratory distress. EMS providers should maintain a high index of suspicion for this injury in patients with chest trauma.

3. Diaphragmatic Injury: A diaphragmatic injury can lead to herniation of abdominal contents into the chest, causing respiratory compromise and other complications. EMS providers should be aware of the potential signs and manage accordingly.

4. Esophageal Injury: Trauma to the chest can cause damage to the esophagus, leading to leakage of gastric contents into the chest cavity. EMS providers should be vigilant for signs of mediastinitis and infection.

5. Open Pneumothorax (Sucking Chest Wound): An open wound in the chest allows air to enter the pleural space, leading to a pneumothorax. It can impair ventilation and lead to respiratory distress. EMS providers must apply airtight seals to manage it.

6. Tension Pneumothorax: This occurs when air accumulates in the pleural space and compresses the lung, causing pressure on the heart and other vital structures. It can lead to cardiovascular collapse and requires immediate intervention, such as needle decompression.

7. Massive Hemothorax: This injury involves the accumulation of blood in the pleural space, which can impair lung function and cause hypovolemic shock. It may result from chest trauma, and EMS providers need to identify and manage it.

8. Flail Chest: A flail chest occurs when a segment of the ribcage becomes detached due to multiple rib fractures. It can impair ventilation and lead to respiratory failure. Stabilization and pain management are essential.

9. Cardiac Tamponade: This is a condition where blood or fluid accumulates in the pericardial sac, compressing the heart and impairing its function. It can cause hemodynamic instability and requires immediate intervention.

10. Aortic Disruption: Trauma can cause a tear or rupture in the aorta, which can lead to massive internal bleeding and shock. Early recognition and rapid transport are essential.

11. Myocardial Contusion: Blunt chest trauma can lead to a bruising or injury to the heart muscle, causing arrhythmias, myocardial infarction, or heart failure. EMS providers need to monitor for signs of cardiac injury.

12. Pulmonary Contusion: Similar to lung contusion, pulmonary contusion involves bruising of lung tissue, which can lead to impaired gas exchange and respiratory distress. EMS providers should monitor for signs of respiratory compromise.

EMS providers need to be aware of these chest injuries and their potential consequences because early recognition and appropriate management can be life-saving. 

Proper assessment, stabilization, and rapid transport to a medical facility for definitive care are critical in the prehospital setting for patients with these injuries.
