Obstructive Uropathy. We start with the anatomy of obstructive uropathy and how that translates into the differential diagnosis. We then discuss each differential diagnosis and whether that causes unilateral versus bilateral hydronephrosis and partial versus complete obstruction. We dive into the signs and symptoms of obstructive uropathy. The pathophysiology that leads to acute kidney injury. Laboratory workup including the utility of FeNa and FeUrea. Imaging modalities, their pros and cons. Management of this disease. And finally prognosis.

💧In this podcast, we dive deep into post-obstructive diuresis (POD), an important clinical condition that can arise after the relief of urinary tract obstruction. Learn about the pathophysiology, diagnosis, management strategies, fluid repletion techniques, and potential complications associated with POD. This video is a comprehensive guide for medical students, residents, interested public, and healthcare professionals to understand the complexities of post-obstructive diuresis and its clinical significance.

In this podcast we will discuss the similarities and differences between Nephritic Syndrome, also know as Glomerulonephritis, and Nephrotic Syndrome. These two disease states are a spectrum with varying levels of similarities and differences, which can make things confusing. We will unveil the intricacies between these two disease states by discussing their clinical features and pathology. We will line them up side by side and discuss each characteristic as compared to the other. Finally understand the differences and similarities between these two disease states!

The Intra-Aortic Balloon Pump (IABP) explained clearly! This is a temporary hemodynamic augmentation device that is placed in the aorta to assist the heart in delivering blood to the rest of the body. We will discuss what this device is, its anatomic placement/alignment, and how it changes the arterial waveform. We will then dive into the hemodynamic augmentation and repercussions of the IABP, such as augmenting diastolic pressure and possibly increasing myocardial perfusion. All of this will be in relation to how the IABP works. We then dive into indications for placement and contraindications, as well as complications.

In this podcast we will discuss the varying normal pressures within the cardiac chambers including the inferior/superior vena cava pressures, right atrial pressure, right ventricular pressure, pulmonary artery pressure, pulmonary capillary wedge pressure, left atrial pressure, left ventricular pressure, and aortic pressure. We will depict this in two different ways, both of which will hopefully make them easier to remember! Additionally, we are going to discuss the bedside invasive monitoring techniques that can be used to determine these pressures including central venous pressures with a central venous catheter and the pulmonary artery or Swan Ganz catheter measuring pulmonary capillary wedge pressure. We will spend a little extra time discussing the wedge pressure, specifically how it is taken to better grasp this tricky concept.

In this podcast we will introduce anti-arrhythmic medications, their classes, and lay the foundation for understanding them as related to the cardiac action potential. We will explain clearly and imply the four different classes of anti-arrhythmias including Class I (sodium channel blockers), Class II (beta-blockers), Class III (potassium channel blockers), and Class IV (calcium channel blockers). We will explain their functionality as related to the phases (0-4) of the cardiac action potential.

In this podcast we will discuss cardiac output and the FICK equation. We will begin by discussing cardiac output both as a concept and as an equation related to heart rate and stroke volume. We will discuss the normal cardiac output, cardiac index, and stroke volume. We will then dive into how to clinically derive the cardiac output using different clinical parameters. This will transition into the FICK equation. We will go through how to derive the FICK equation using different concepts including oxygen consumption, arterial saturation, venous saturation, dissolve oxygen, and hemoglobin. We will clearly explain how to understand the FICK equation and then hot to be able to better apply it in the clinical setting. Lastly, we will go over what clinical information you need to get the data required to calculate the FICK and subsequent cardiac output.

In this podcast we will discuss Class I Anti-Arrhythmic Drugs. We will start by discussing their sodium channel blockade mechanism as related to the cardiac action potential. We will also go into their variable effect on the potassium channels and how that changes the refractory period. We will relate their mechanism to how the cardiac action potential phases change and will draw out the new shape of these action potentials. We will then dive into indications and dysrhythmias. Lastly, we will discuss each subclass, the drugs included in each subclass, and again the changes within each subclass in the cardiac action potential.

In this podcast we will discuss Class II anti-arrhythmic drugs, also known as the beta blockers. We will begin by discussing their general mechanism of action. We will then dive into beta 1 versus beta 2 receptors, where they are found, and the different effects that blocking these two receptors can cause. We will then hone in on a list of cardioselective versus non-cardioselective beta blockers (with a pneumonic to assist in memorization!). Lastly, we will talk about the various indications for using beta blockers both including and beyond dysrhythmias.

In this podcast we will discuss Class III anti-arrhythmic drugs, the potassium channel blockers. We will begin by discussing what these medications are and how they work as related to the cardiac action potential. We will then dive deeper into their prolongation of the QT interval as related to their prevention of re-entrant tachydysrrhythmias. Lastly, we will go through each of the potassium channel blockers, which arrhythmias they treat, and details about their mechanisms, adverse effects, and more.
