Arguments We Are Tired of Having
Welcome back to another episode of EM Over Easy. Today, we’re tackling a topic that resonates deeply with many emergency medicine professionals—those repetitive and exhausting arguments that seem to never end. Despite advancements in medical practice and technology, there are still some discussions that we find ourselves having over and over again.
The Never-Ending ABG vs. VBG Debate
One of the most persistent and frustrating arguments in emergency medicine is the arterial blood gas (ABG) versus venous blood gas (VBG) debate. Despite considerable evidence supporting the use of VBGs in many clinical situations, the debate continues to rage on.
Why We Prefer VBGs
- Less Painful: Drawing a venous sample is generally less painful for patients compared to an arterial puncture.
- Quicker and Easier: VBGs can be obtained more quickly and easily, especially in a busy emergency department (ED) setting.
- Sufficient Accuracy: For many conditions, VBGs provide sufficient accuracy for clinical decision-making, such as assessing pH, pCO2, and lactate levels.
The Persistent Resistance
Despite these benefits, resistance remains. Some colleagues insist on ABGs, citing concerns about accuracy for specific parameters like oxygenation. This often leads to repetitive explanations and justifications, draining time and energy that could be better spent on patient care.
The “Just Get an ABG” Mentality
Another related argument is the “just get an ABG” mentality from admitting teams. They often request ABGs as a blanket requirement, regardless of the clinical scenario.
The Real Issue
The core issue here is a lack of trust or understanding about the utility of VBGs. This results in needless debate and delays in patient care.
Colorimetric vs. Waveform Capnography in Resuscitation
In critical scenarios, such as resuscitations, the choice between colorimetric and waveform capnography can spark heated debates. Waveform capnography is more accurate and provides continuous monitoring, yet some practitioners still rely on colorimetric devices.
Why Waveform Capnography?
- Continuous Monitoring: Provides real-time feedback on ventilation and circulation.
- More Accurate: Reduces the risk of false positives/negatives.
The Resistance
Some resist adopting waveform capnography due to familiarity with colorimetric devices or a lack of training on the newer technology. This resistance can compromise patient care and lead to unnecessary arguments.
The Importance of Timely Urine Samples
Collecting urine samples can be another point of contention, especially when dealing with time-sensitive cases.
Common Frustrations
- Delayed Samples: Waiting for patients to provide a sample can slow down the diagnostic process.
- Lack of Urgency: Some staff may not prioritize obtaining samples promptly, leading to delays.
Magnesium Levels in the ED
Magnesium levels are another area of frequent debate. While some argue they’re essential, others see them as unnecessary in many cases.
The Argument
- Pro-Magnesium: Useful for diagnosing and managing specific conditions like preeclampsia or severe asthma.
- Anti-Magnesium: Often seen as overkill for routine cases.
The Undifferentiated Admit
Lastly, the argument over admitting undifferentiated patients is a daily struggle. The expectation that all diagnoses must be fully vetted before admission overlooks the complexity of many cases.
The Reality
- Complex Patients: Many patients present with multiple, overlapping issues that can’t be fully resolved in the ED.
- Hospital’s Role: The hospital exists to provide extended care and further diagnostic work-up, not just to house patients with clear-cut diagnoses.
Conclusion
These recurring arguments can be frustrating, but they’re also a testament to the complexity and evolving nature of emergency medicine. It’s crucial to continue educating and advocating for best practices, even if it means having the same conversations multiple times.
If you’re tired of these arguments too, you’re not alone. Let’s work together to push for evidence-based practices and improve the efficiency and effectiveness of our care.
