Digest

This podcast episode delves into a complex medical case involving a 68-year-old male experiencing severe vomiting of blood. The discussion covers the initial frustration with software interfaces, a clarification of firmware, and an introduction to the EMS 2020 podcast and its continuing education platform. The case study features paramedics Sox Fox, Knoxbox, and student Brick Chicks, highlighting that experience isn't solely defined by years of service. The Noodle Poodle Puddle County Ambulance Service and its hospital infrastructure are described. The core of the episode focuses on the dispatch and management of a patient with a suspected GI bleed, possibly related to a recent tongue procedure. Key assessment points include the patient's vitals, level of consciousness, and the challenge of estimating blood loss. The crew debates the significance of arterial versus venous bleeding in this context and discusses interventions like the Ab Pad, TXA, and nebulized epinephrine. Transport decisions are analyzed, including consultation with online medical control and the choice of destination hospital. The episode details in-transport interventions, IV complications, and the patient's condition upon arrival at the ED, where rapid blood transfusion via a Life Flow device and intubation are performed. The case is recapped with a critical analysis of decision-making, patient assessment, and systemic issues in EMS. Treatment strategies for bleeding control, the comparison of nebulized epinephrine and TXA, and the role of crystalloid infusions are explored. The importance of BLS interventions for airway management and the patient's eventual recovery after successful cauterization and surgery are also covered.

00:11:29

Quality Assurance and Flight Patient Protocols

The discussion covers the stringent quality assurance processes within the ambulance service, particularly concerning decisions to fly patients and the pressures involved.

00:14:41

Volunteer Fire Department and Case Dispatch: Vomiting Blood

The volunteer EMR-level fire department is introduced. The EMS crew receives a critical dispatch for a 68-year-old male experiencing persistent vomiting of blood.

00:18:54

Initial Scene Assessment and Patient Condition

Upon arrival, the crew finds the patient actively vomiting blood. Initial assessments are made regarding the blood's appearance and the unclear source of bleeding.

00:24:11

Patient Assessment and History: Mr. Freezy Breeze

A detailed assessment of the patient, Mr. Freezy Breeze, is conducted, including vitals and level of consciousness. The family provides a history suggesting the bleeding may be related to a recent tongue procedure.

00:30:33

Bleeding Type Significance and Initial Interventions

The relevance of distinguishing between arterial and venous bleeding in GI bleeds is discussed. The crew decides to use an Ab Pad to help control the bleeding and prepares for transport.

00:41:22

Transport Decision and Medical Control Consultation

The patient is transported to the closest hospital after consulting online medical control. TXA and nebulized epinephrine are administered during the transport preparation.

00:50:22

Treatment Strategy and In-Transport Management

The treatment strategy, including nebulized epinephrine and TXA, is discussed, along with potential complications. During transport, the patient receives end-tidal CO2 monitoring, an IV, and further nebulized epinephrine.

00:56:21

IV Complication and Vitals Monitoring

The patient experiences an IV dislodgement and becomes diaphoretic. A new IV is established, and medications are re-administered while vitals continue to be monitored.

00:59:50

Pre-Hospital Arrival Observations and Hand-off

Shortly before hospital arrival, the patient's vitals remain stable, though they are alert but tired. Upon arrival at the ED, the patient's condition has worsened, and a detailed handover is provided to the hospital staff.

01:01:52

Advanced Interventions: Life Flow and Intubation

The doctor utilizes a Life Flow device for rapid blood transfusion. An intubation attempt is made, which is ultimately successful after initial resistance.

01:05:14

Case Recap and Decision-Making Analysis

The case is recapped, focusing on the transport decision, patient condition, and a critical analysis of the crew's actions and assumptions throughout the call.

01:08:54

Patient Assessment Nuances and Rationale

The speakers discuss acknowledging the patient's severity and the rationale behind decisions like allowing the patient to walk. They delve into the complexities of patient assessment, potential misinterpretations of vital signs, and the need for a comprehensive approach.

01:17:44

Systemic Issues, Triage, and ABCs Evaluation

Potential systemic problems in EMS, including undertriage and resource conservation, are explored. The critical initial assessment of airway, breathing, and circulation (ABCs) is debated, weighing visual cues against tactile assessments.

01:19:47

History vs. Physical Examination and Treatment Strategies

The balance between patient history and physical examination is discussed, with concerns about over-reliance on history. Treatment options for bleeding control, including gauze, rubber bands, nebulized epinephrine, and TXA, are considered.

Keywords

Q&A

• What is the main frustration the speaker has with most software?

  The speaker is frustrated by software that bombards users with numerous notifications, update prompts, and integration announcements upon startup, hindering immediate access to the application's core functions.

• How does firmware differ from regular software?

  Firmware is software permanently embedded into a hardware device's memory, controlling its fundamental operations. Regular software, on the other hand, is typically installed on a computer and can be updated or changed more easily.

• What is the significance of the "Sox Fox" case study in relation to experience?

  The case highlights that the number of years a paramedic has been in service doesn't always correlate with their experience in handling critical or rare events, such as pediatric codes or major traumas.

• What is the "Shock Index" and why is it relevant in this case?

  The Shock Index is calculated by dividing the heart rate by the systolic blood pressure. A patient with a Shock Index above 0.9 often indicates potential hypoperfusion, as seen with Mr. Freezy Breeze.

• Why was the decision of where to transport the patient a dilemma?

  The dilemma arose because the closest hospital had limited services, while the hospital where the patient had a recent procedure was an hour away. The crew was concerned about the patient's blood loss and ability to tolerate the longer transport.

• What is the purpose of online medical control?

  Online medical control provides remote physician guidance to pre-hospital providers, assisting with complex patient care decisions, treatment protocols, and transport destinations.

• What is the "Life Flow" device and its benefit?

  The Life Flow is a device for rapid blood transfusion, enabling quick infusion of large blood volumes, crucial in critical bleeding situations, and noted for its cost-effectiveness.

• What was the outcome of the intubation attempt?

  The doctor encountered resistance during the intubation attempt but was ultimately successful in passing the tube without needing to perform a surgical airway.

• What are the potential treatments discussed for controlling oral bleeding?

  Treatments discussed include direct pressure with ABD pads, nebulized epinephrine, and nebulized tranexamic acid (TXA), with TXA showing promise due to fewer side effects.

• What are the potential drawbacks of using large amounts of crystalloid infusions?

  Crystalloid infusions can lead to hypothermia, coagulation issues, and electrolyte imbalances, potentially worsening the condition in patients who are already maintaining blood pressure.
