EMCrit 45 – Acid Base – Part II
This second lecture discusses a quantitative approach to acid base management. I lay out the formula I use to approach an acid-base problem.
EMCrit 46 – Acid Base – Part III
In part III, we go through 2 cases of acid base abnormalities step by step.
EMCrit 44 – Acid Base – Part I
This lecture discusses a quantitative approach to acid base management. This is also known as the Fencl-Stewart approach, the strong-ion approach or the physicochemical approach. It provides explanations for why acid base disorders occur in human pathophysiology.
EMCrit 96 – Acid Base – Part V – Enough with the Bicarb Already
More on Bicarb in the Critically Ill and a discussion with John Kellum, MD
EMCrit 50 – Acid Base – Part IV – Choose the Solution Based on the Problem
This is Part 4 of the Acid Base saga. In this episode, I discuss the acid base effects of fluids and when and how to use sodium bicarbonate.
EMCrit 97 – Acid-Base – Part VI – Chloride-Free Sodium
So last podcast, I bashed on sodium bicarbonate or as John Kellum and David Story call it: chloride-free sodium. This episode I talk about all the good reasons to use NaBicarb.
EMCrit 227 – Acid Base Ep. 7 – Bicarb Updates, Quantitative Approach, and Prof. David Story
Bicar-ICU changes my practice with bicarb infusions and let’s end the great lactate debate on EMCrit 227:

Fluid selection using pH-guided resuscitation
0 PART 1: Fluid selection for resuscitation of hypovolemic, hyperkalemic renal failure 0 Introduction with a case 0 An elderly man on an ACE inhibitor and NSAIDs presents to the emergency department after a few days of severe norovirus gastroenteritis with a creatinine of 5 mg/dL, a bicarbonate of 15 mEq/L, and a potassium of […]
IBCC chapter & cast – Approach to pH diagnosis
According to Albert Einstein, “Everything should be made as simple as possible, but not simpler.” This is a similar sentiment to Occam’s Razor. Acid-base analysis is a good example of this principle. It’s possible to make things extraordinarily fancy and complex. To analyze pH status we could obtain an ABG, complete blood count, calcium, magnesium, […]
Mythbusting: Correcting the anion gap for albumin is not helpful
0 Introduction 0 In 1998 Figge reported a strong linear relationship between anion gap and albumin concentration, which has led to the widespread recommendation to correct anion gap for albumin. It was proposed that since albumin is an anion, failing to correct for a low albumin level could allow an anion-gap acidosis to go undetected. […]

CONTENTS Proximal tubule Thick ascending loop of henle Distal convoluted tubule Cortical collecting duct (CCD) Questions & discussion proximal tubule acid-base management reabsorption of bicarbonate The proximal tubule normally reabsorbs 80% of filtered bicarbonate. Proximal (type 2) RTA involves dysfunction of bicarbonate reabsorption, either: (a) Impaired HCO3 transport across the basolateral membrane (NBCe1). (b) Inhibition […]
