Metabolic Acidosis--What It Means and What To Do Jonathan Elliott, MA, Vet MB, PhD, Cert SAC, DECVPT Metabolic acidosis is said to be an inevitable consequence of chronic kidney disease (CKD) and, therefore, part of the uraemic syndrome. The adverse effects of metabolic acidosis to the kidney disease patient are wide-ranging and serious. Even mild metabolic acidosis stimulates protein catabolism and reduces protein synthesis and so contributes to the chronic wasting characteristic of renal failure. Severe metabolic acidosis (arterial pH <7.2) has haemodynamic effects, reducing myocardial contractility, causing arteriolar vasodilation and peripheral venoconstriction. Gastrointestinal abnormalities occur in the uraemic syndrome, leading to vomiting, nausea and gastric atony. Metabolic acidosis may contribute to these abnormalities. With sustained acidosis, perhaps the most important effects in human medicine are on the skeletal system because a negative calcium balance ensues. Increased bone resorption occurs and is coupled with reduced bone formation thus contributing to uraemic osteodystrophy [1]. In children, effects on bone turnover can be striking leading to marked stunting of growth, effects which can be reversed by alkali therapy. Excessive dietary acidification in normal cats can cause increased urinary loss of calcium and reduced bone mineral density [2]. Finally, metabolic acidosis has been suggested to be one of the factors which may play a role in the progression of CKD because increased ammonia production within the tubular cells has been linked to complement fixation and tubulo-interstitial damage [3,4]. By altering dietary intake of certain acidifying amino acids, providing a source of bicarbonate and modifying the ash content of the diet, it may be possib Continue reading >>

Despite the high incidence of acute metabolic acidosis, there are no reliable human data to enable physicians to accurately diagnose this disorder. In addition, there is uncertainty about the direction and magnitude of plasma potassium changes in acute metabolic acidosis. The systemic and renal acid-base, electrolyte, and endocrine response to acute acid loads (imposed by three timed NH4Cl infusions into the duodenum, 0.9 mmol of NH4Cl per kg of body weight over 30 min each) was characterized in six healthy male subjects in whom a metabolic steady-state had been established. Arterialized blood CO2 tension decreased by 0.85 mmHg per mmol/L decrease in plasma bicarbonate concentration and blood hydrogen ion concentration increased by 0.45 nmol/L per mmol/L decrease in plasma bicarbonate concentration. Plasma potassium did not change significantly (+0.02 ± 0.02 mmol/L per mmol decrease in plasma bicarbonate concentration). Plasma insulin increased and plasma glucagon levels decreased in acute metabolic acidosis, while catecholamines and aldosterone were not affected significantly. These data provide the first diagnostic criteria for the Continue reading >>

Metabolic Acidosis In Emergency Medicine

Metabolic Acidosis In Emergency Medicine

Background Metabolic acidosis is a clinical disturbance characterized by an increase in plasma acidity. Metabolic acidosis should be considered a sign of an underlying disease process. Identification of this underlying condition is essential to initiate appropriate therapy. This article discusses the differential diagnosis of metabolic acidosis and presents a scheme for identifying the underlying cause of acidosis by using laboratory tests that are available in the emergency department. Clinical strategies for treating metabolic acidosis are also reviewed. Continue reading >>

Anion Gap (blood) - Health Encyclopedia - University Of Rochester Medical Center

If you may have swallowed a poison, such as wood alcohol, salicylate (in aspirin), and ethylene glycol (in antifreeze), your provider may test your blood for it. If your provider thinks you have ketoacidosis, you might need a urine dipstick test for ketone compounds. Ketoacidosis is a health emergency. Many things may affect your lab test results. These include the method each lab uses to do the test. Even if your test results are different from the normal value, you may not have a problem. To learn what the results mean for you, talk with your healthcare provider. Results are given in milliequivalents per liter (mEq/L). Normal results are 3 to 10mEq/L, although the normal level may vary from lab to lab. If your results are higher, it may mean that you have metabolic acidosis. Hypoalbuminemia means you haveless albumin protein than normal. If you have this condition, your expected normal result must be lower. The test requires a blood sample, which is drawn through a needle from a vein in your arm. Taking a blood sample with a needle carries risks that include bleeding, infection, bruising, or feeling dizzy. When the needle pricks your arm, you may feel a slight stinging sensation or pain. Afterward, the site may be slightly sore. Being dehydrated or retaining water in your body can affect your results. Antibiotics such as penicillin can also affect your results. You don't need to prepare for this test. But be sure your healthcare provider knows about all medicines, herbs, vitamins, and supplements you are taking. This includes medicines that don't need a prescription and any illicit drugs you may use. Continue reading >>

Metabolic Acidosis Question!!

Metabolic Acidosis Question!!

If the patient is having a gastritis? is this metabolic acidosis? and if the patient is having pulmonary embolism? is that respiratory acidosis? Metabolic experts Please help me to understand this concept! Gastritis--> vomiting-->Metabolic AHHHHLKalosis. for your pulmonary question, i would say time matters. they are usually in acidosis before they go into alkalosis Gastritis--> vomiting-->Metabolic AHHHHLKalosis. for your pulmonary question, i would say time matters. they are usually in acidosis before they go into alkalosis I love this! Very easy to remember. I always have to think "OK, vomiting means you're losing stomach acid. If you lose acid, then you have too much base = alkalosis" or "Diarrhea means you're losing base. If you lose base, then you have too much acid = acidosis". Much easier to remember AHHHLKalosis & ASSSidosis I'm also going to leave you with GrnTea's wonderful ABGs Made Simple post. This got me through nursing school !!! While some of this appears in other places on the net, I wrote it first , and I hope it is as helpful to you as it has been for many others. You want simple ABGs? Piece o' cake. People who have seen this before, well, just scroll on by. Newbies who want a brief ABG's refresher, take out your pencils and a piece of paper, cuz you'll need to do a bit of drawing . I taught ABG interpretation for yrs in a way that made it pretty foolproof. You will make your own key to interpret ABG's, and will be able to reproduce it from memory any time you need to with very little trouble if you learn a very few **key concepts**, labeled **thus**.. Take a piece of paper. Make a big box on it, then draw vertical and horizontal lines on it so you have four boxes. I will try to make this come out, but...you should have where the four boxes a,b,c Continue reading >>

Simple Method Of Acid Base Balance Interpretation

Simple Method Of Acid Base Balance Interpretation

A FOUR STEP METHOD FOR INTERPRETATION OF ABGS Usefulness This method is simple, easy and can be used for the majority of ABGs. It only addresses acid-base balance and considers just 3 values. pH, PaCO2 HCO3- Step 1. Use pH to determine Acidosis or Alkalosis. ph < 7.35 7.35-7.45 > 7.45 Acidosis Normal or Compensated Alkalosis Step 2. Use PaCO2 to determine respiratory effect. PaCO2 < 35 35 -45 > 45 Tends toward alkalosis Causes high pH Neutralizes low pH Normal or Compensated Tends toward acidosis Causes low pH Neutralizes high pH Step 3. Assume metabolic cause when respiratory is ruled out. You'll be right most of the time if you remember this simple table: High pH Low pH Alkalosis Acidosis High PaCO2 Low PaCO2 High PaCO2 Low PaCO2 Metabolic Respiratory Respiratory Metabolic If PaCO2 is abnormal and pH is normal, it indicates compensation. pH > 7.4 would be a compensated alkalosis. pH < 7.4 would be a compensated acidosis. These steps will make more sense if we apply them to actual ABG values. Click here to interpret some ABG values using these steps. You may want to refer back to these steps (click on "linked" steps or use "BACK" button on your browser) or print out this page for reference. Step 4. Use HC03 to verify metabolic effect Normal HCO3- is 22-26 Please note: Remember, the first three steps apply to the majority of cases, but do not take into account: the possibility of complete compensation, but those cases are usually less serious, and instances of combined respiratory and metabolic imbalance, but those cases are pretty rare. "Combined" disturbance means HCO3- alters the pH in the same direction as the PaCO2. High PaCO2 and low HCO3- (acidosis) or Low PaCO2 and high HCO3- (alkalosis). Continue reading >>

Potassium And Acidosis

Potassium And Acidosis

Balance among electrically charged atoms and molecules is essential to maintaining chemical equilibrium in your body. Potassium is the most abundant, positively charged atom inside your cells. Because acids and potassium both have a positive electrical charge in your body, their concentrations are interdependent. Medical conditions that cause an overabundance of acids in your blood, known as acidosis, may affect your blood potassium level, and vice versa. Video of the Day Metabolic acidosis is an abnormally low blood pH caused by overproduction of acids or failure of your kidneys to rid the body of acids normally. With metabolic acidosis, your blood has an abnormally high level of positively charged hydrogen atoms, or hydrogen ions. To reduce the acidity of your blood, hydrogen ions move from your circulation into your cells in exchange for potassium. The exchange of hydrogen for potassium ions helps relieve the severity of acidosis but may cause an abnormally high level of blood potassium, or hyperkalemia. Drs. Kimberley Evans and Arthur Greenberg reported in a September 2005 article published in the "Journal of Intensive Care Medicine" that there is a 0.3 to 1.3 mmol/L increase in blood potassium for every 0.1 decrease in pH with metabolic acidosis. Metabolic Acidosis Recovery Correction of the underlying medical problem responsible for metabolic acidosis typically leads to normalization of your blood pH. Although blood potassium is typically elevated with metabolic acidosis, a substantial amount of your total body potassium stores can be lost through the kidneys, causing a total body deficit. As your blood pH returns to normal, potassium moves from your bloodstream back into your cells. If your total body potassium stores have been depleted, your blood concentration Continue reading >>

Sodium Bicarbonate Therapy In Patients With Metabolic Acidosis

Sodium Bicarbonate Therapy In Patients With Metabolic Acidosis

The Scientific World Journal Volume 2014 (2014), Article ID 627673, 13 pages Nephrology Division, Hospital General Juan Cardona, Avenida Pardo Bazán, s/n, Ferrol, 15406 A Coruña, Spain Academic Editor: Biagio R. Di Iorio Copyright © 2014 María M. Adeva-Andany et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. Abstract Metabolic acidosis occurs when a relative accumulation of plasma anions in excess of cations reduces plasma pH. Replacement of sodium bicarbonate to patients with sodium bicarbonate loss due to diarrhea or renal proximal tubular acidosis is useful, but there is no definite evidence that sodium bicarbonate administration to patients with acute metabolic acidosis, including diabetic ketoacidosis, lactic acidosis, septic shock, intraoperative metabolic acidosis, or cardiac arrest, is beneficial regarding clinical outcomes or mortality rate. Patients with advanced chronic kidney disease usually show metabolic acidosis due to increased unmeasured anions and hyperchloremia. It has been suggested that metabolic acidosis might have a negative impact on progression of kidney dysfunction and that sodium bicarbonate administration might attenuate this effect, but further evaluation is required to validate such a renoprotective strategy. Sodium bicarbonate is the predominant buffer used in dialysis fluids and patients on maintenance dialysis are subjected to a load of sodium bicarbonate during the sessions, suffering a transient metabolic alkalosis of variable severity. Side effects associated with sodium bicarbonate therapy include hypercapnia, hypokalemia, ionized hypocalcemia, and QTc inter Continue reading >>

What Is Metabolic Acidosis?

What Is Metabolic Acidosis?

Metabolic acidosis happens when the chemical balance of acids and bases in your blood gets thrown off. Your body: Is making too much acid Isn't getting rid of enough acid Doesn't have enough base to offset a normal amount of acid When any of these happen, chemical reactions and processes in your body don't work right. Although severe episodes can be life-threatening, sometimes metabolic acidosis is a mild condition. You can treat it, but how depends on what's causing it. Causes of Metabolic Acidosis Different things can set up an acid-base imbalance in your blood. Ketoacidosis. When you have diabetes and don't get enough insulin and get dehydrated, your body burns fat instead of carbs as fuel, and that makes ketones. Lots of ketones in your blood turn it acidic. People who drink a lot of alcohol for a long time and don't eat enough also build up ketones. It can happen when you aren't eating at all, too. Lactic acidosis. The cells in your body make lactic acid when they don't have a lot of oxygen to use. This acid can build up, too. It might happen when you're exercising intensely. Big drops in blood pressure, heart failure, cardiac arrest, and an overwhelming infection can also cause it. Renal tubular acidosis. Healthy kidneys take acids out of your blood and get rid of them in your pee. Kidney diseases as well as some immune system and genetic disorders can damage kidneys so they leave too much acid in your blood. Hyperchloremic acidosis. Severe diarrhea, laxative abuse, and kidney problems can cause lower levels of bicarbonate, the base that helps neutralize acids in blood. Respiratory acidosis also results in blood that's too acidic. But it starts in a different way, when your body has too much carbon dioxide because of a problem with your lungs. Continue reading >>

Causes Of Lactic Acidosis

Causes Of Lactic Acidosis

INTRODUCTION AND DEFINITION Lactate levels greater than 2 mmol/L represent hyperlactatemia, whereas lactic acidosis is generally defined as a serum lactate concentration above 4 mmol/L. Lactic acidosis is the most common cause of metabolic acidosis in hospitalized patients. Although the acidosis is usually associated with an elevated anion gap, moderately increased lactate levels can be observed with a normal anion gap (especially if hypoalbuminemia exists and the anion gap is not appropriately corrected). When lactic acidosis exists as an isolated acid-base disturbance, the arterial pH is reduced. However, other coexisting disorders can raise the pH into the normal range or even generate an elevated pH. (See "Approach to the adult with metabolic acidosis", section on 'Assessment of the serum anion gap' and "Simple and mixed acid-base disorders".) Lactic acidosis occurs when lactic acid production exceeds lactic acid clearance. The increase in lactate production is usually caused by impaired tissue oxygenation, either from decreased oxygen delivery or a defect in mitochondrial oxygen utilization. (See "Approach to the adult with metabolic acidosis".) The pathophysiology and causes of lactic acidosis will be reviewed here. The possible role of bicarbonate therapy in such patients is discussed separately. (See "Bicarbonate therapy in lactic acidosis".) PATHOPHYSIOLOGY A review of the biochemistry of lactate generation and metabolism is important in understanding the pathogenesis of lactic acidosis [1]. Both overproduction and reduced metabolism of lactate appear to be operative in most patients. Cellular lactate generation is influenced by the "redox state" of the cell. The redox state in the cellular cytoplasm is reflected by the ratio of oxidized and reduced nicotine ad Continue reading >>

Metabolic Acidosis

Metabolic Acidosis

Metabolic acidosis occurs when the body produces too much acid. It can also occur when the kidneys are not removing enough acid from the body. There are several types of metabolic acidosis. Diabetic acidosis develops when acidic substances, known as ketone bodies, build up in the body. This most often occurs with uncontrolled type 1 diabetes. It is also called diabetic ketoacidosis and DKA. Hyperchloremic acidosis results from excessive loss of sodium bicarbonate from the body. This can occur with severe diarrhea. Lactic acidosis results from a buildup of lactic acid. It can be caused by: Alcohol Cancer Exercising intensely Liver failure Medicines, such as salicylates Other causes of metabolic acidosis include: Kidney disease (distal renal tubular acidosis and proximal renal tubular acidosis) Poisoning by aspirin, ethylene glycol (found in antifreeze), or methanol Continue reading >>

What Is Acidosis? Acidosis Causes & Treatment | High Alkaline Diet

DEFINITION: Acidosis is an increased acidity in the blood and other body tissue. Acidosis is said to occur when arterial pH falls below 7.35. The pH level of our blood affects every cell in our body. Chronic acidosis corrodes body tissue, and if left unchecked, will interrupt all cellular activities and functions. HIGH ACID-FORMING FOODS and DIETS all lead to ACIDOSIS. Living a fast-paced daily lifestyle, such as eating on the run, will lead people to face constant symptoms of indigestion and growing endangerment of over-acidification (Acidosis) of the body cells, which will interrupt cellular activities and functions. It is a major root of sickness and disease. Having our cells constantly exposed to an acidic environment leads to acidosis and then chronic acidosis and, finally, various forms of disease such as cancer and many more! Studies have shown that an acidic, anaerobic (which is also the lack of oxygen) body environment encourages the breeding of fungus, mold, bacteria, and viruses. As a result, our inner biological terrain shifts from a healthy oxygenated, alkaline environment to an unhealthy acidic one (acidic pH scale). This forces the body to constantly deplete its cellular energy to neutralize and detoxify these acids before they can act as poisons in and around the cells, ultimately changing the environment of each cell and finally compromising its immune system, leaving it vulnerable to the ravages of disease to take a foothold in the body. When our body pH becomes overly acidic, it starts to set up defense mechanisms to keep the damaging acids from entering the vital organs. Modern Day Athletes and Acid-Forming Foods Unfortunately, Modern Day Athletes and/or Non-Athletes have been raised in a fast food environment that is more concerned about convenienc Continue reading >>

Metabolic Acidosis

Metabolic Acidosis

Metabolic Acidosis Definition Metabolic acidosis is a pH imbalance in which the body has accumulated too much acid and does not have enough bicarbonate to effectively neutralize the effects of the acid. Description Metabolic acidosis, as a disruption of the body's acid/base balance, can be a mild symptom brought on by a lack of insulin, a starvation diet, or a gastrointestinal disorder like vomiting and diarrhea. Metabolic acidosis can indicate a more serious problem with a major organ like the liver, heart, or kidneys. It can also be one of the first signs of drug overdose or poisoning. Causes and symptoms Metabolic acidosis occurs when the body has more acid than base in it. Chemists use the term "pH" to describe how acidic or basic a substance is. Based on a scale of 14, a pH of 7.0 is neutral. A pH below 7.0 is an acid; the lower the number, the stronger the acid. A pH above 7.0 is a base; the higher the number, the stronger the base. Blood pH is slightly basic (alkaline), with a normal range of 7.36-7.44. Acid is a natural by-product of the breakdown of fats and other processes in the body; however, in some conditions, the body does not have enough bicarbonate, an acid neutralizer, to balance the acids produced. This can occur when the body uses fats for energy instead of carbohydrates. Conditions where metabolic acidosis can occur include chronic alcoholism, malnutrition, and diabetic ketoacidosis. Consuming a diet low in carbohydrates and high in fats can also produce metabolic acidosis. The disorder may also be a symptom of another condition like kidney failure, liver failure, or severe diarrhea. The build up of lactic acid in the blood due to such conditions as heart failure, shock, or cancer, induces metabolic acidosis. Some poisonings and overdoses (aspirin, Continue reading >>

(Video) Overview of Acid-Base Maps and Compensatory Mechanisms By James L. Lewis, III, MD, Attending Physician, Brookwood Baptist Health and Saint Vincent’s Ascension Health, Birmingham Metabolic acidosis is primary reduction in bicarbonate (HCO3−), typically with compensatory reduction in carbon dioxide partial pressure (Pco2); pH may be markedly low or slightly subnormal. Metabolic acidoses are categorized as high or normal anion gap based on the presence or absence of unmeasured anions in serum. Causes include accumulation of ketones and lactic acid, renal failure, and drug or toxin ingestion (high anion gap) and GI or renal HCO3− loss (normal anion gap). Symptoms and signs in severe cases include nausea and vomiting, lethargy, and hyperpnea. Diagnosis is clinical and with ABG and serum electrolyte measurement. The cause is treated; IV sodium bicarbonate may be indicated when pH is very low. Metabolic acidosis is acid accumulation due to Increased acid production or acid ingestion Acidemia (arterial pH < 7.35) results when acid load overwhelms respiratory compensation. Causes are classified by their effect on the anion gap (see The Anion Gap and see Table: Causes of Metabolic Acidosis ). Lactic acidosis (due to physiologic processes) Lactic acidosis (due to exogenous toxins) Toluene (initially high gap; subsequent excretion of metabolites normalizes gap) HIV nucleoside reverse transcriptase inhibitors Biguanides (rare except with acute kidney injury) Normal anion gap (hyperchloremic acidosis) Renal tubular acidosis, types 1, 2, and 4 The most common causes of a high anion gap metabolic acidosis are Ketoacidosis is a common complication of type 1 diabetes mellitus (see diabetic ketoacidosis ), but it also occurs with chronic alcoholism (see alcoholic ketoacidos Continue reading >>
