Kraut, Ira Kurtz; Treatment of acute non-anion gap metabolic acidosis, Clinical Kidney Journal, Volume 8, Issue 1, 1 February 2015, Pages 9399, Acute non-anion gap metabolic acidosis, also termed hyperchloremic acidosis, is frequently detected in seriously ill patients. The most common mechanisms leading to this acidbase disorder include loss of large quantities of base secondary to diarrhea and administration of large quantities of chloride-containing solutions in the treatment of hypovolemia and various shock states. The resultant acidic milieu can cause cellular dysfunction and contribute to poor clinical outcomes. The associated change in the chloride concentration in the distal tubule lumen might also play a role in reducing the glomerular filtration rate. Administration of base is often recommended for the treatment of acute non-anion ga
What is BASAL METABOLIC RATE? What does BASAL METABOLIC RATE mean? BASAL METABOLIC RATE meaning - BASAL METABOLIC RATE definition - BASAL METABOLIC RATE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. Basal metabolic rate (BMR) is the minimal rate of energy expenditure per unit time by endothermic animals at rest. It is reported in energy units per unit time ranging from watt (joule/second) to ml O2/min or joule per hour per kg body mass J/(hkg)). Proper measurement requires a strict set of criteria be met. These criteria include being in a physically and psychologically undisturbed state, in a thermally neutral environment, while in the post-absorptive state (i.e., not actively digesting food). In bradymetabolic animals, such as fish and reptiles, the equivalent term standard metabolic rate (SMR) is used. It follows the same criteria as BMR, but requires the documentation of the temperature at which the metabolic rate was measured. This makes BMR a variant of standard metabolic rate measurement that excludes the temperature data, a practice that has led to problems in defining "standard" rates of metabolism for many mammals. Metabolism comprises the processes that the body needs to function. Basal metabolic rate is the amount of energy expressed in calories that a person needs to keep the body functioning at rest. Some of those processes are breathing, blood circulation, controlling body temperature, cell growth, brain and nerve function, and contraction of muscles. Basal metabolic rate (BMR) affects the rate that a person burns calories and ultimately whether that individual maintains, gains, or loses weight. The basal metabolic rate accounts for about 60 to 75% of the daily calorie expenditure by individuals. It is influenced by several factors. BMR typically declines by 12% per decade after age 20, mostly due to loss of fat-free mass, although the variability between individuals is high. The body's generation of heat is known as thermogenesis and it can be measured to determine the amount of energy expended. BMR generally decreases with age and with the decrease in lean body mass (as may happen with aging). Increasing muscle mass has the effect of increasing BMR. Aerobic (resistance) fitness level, a product of cardiovascular exercise, while previously thought to have effect on BMR, has been shown in the 1990s not to correlate with BMR when adjusted for fat-free body mass. But anaerobic exercise does increase resting energy consumption (see "aerobic vs. anaerobic exercise"). Illness, previously consumed food and beverages, environmental temperature, and stress levels can affect one's overall energy expenditure as well as one's BMR. BMR is measured under very restrictive circumstances when a person is awake. An accurate BMR measurement requires that the person's sympathetic nervous system not be stimulated, a condition which requires complete rest. A more common measurement, which uses less strict criteria, is resting metabolic rate (RMR).
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

Sid Hyperchloremic Acidosis
Strong ions are cations and anions that exist as charged particles dissociated from their partner ions at physiologic pH. The SID (Strong Ion Difference) is the difference between the positively- and negatively-charged strong ions in plasma. This method of evaluating acid-base disorders was developed to help determine the mechanism of the disorder rather than simply categorizing them into metabolic vs. respiratory acidosis/alkalosis as with the Henderson-Hasselbalch equation. Strong cations predominate in the plasma at physiologic pH leading to a net positive plasma charge of approximately +40: SID = [strong cations] [strong anions] = [Na+ + K+ + Ca2+ + Mg2+] [Cl- + lactate- + SO42-] Disturbances that increase the SID increase the blood pH while disorders that decrease the SID lower the plasma pH. According to the law of electroneutrality the sum of positive charges is equal to the sum of negative charges. Therefore the SID must be equal to the sum of weak anions in the body (such as bicarbonate, albumin, and phosphate). Hyperchloremic acidosis may result from chloride replacing lost bicarbonate. Such bicarbonate-wasting conditions may be seen in the kidneys (renal tubular acidosi
The different types of acid-base disturbances are differentiated based on: Origin: Respiratory or metabolic Primary or secondary (compensatory) Uncomplicated or mixed: A simple or uncomplicated disturbance is a single or primary acid-base disturbance with or without compensation. A mixed disturbance is more than one primary disturbance (not a primary with an expected compensatory response). Acid-base disturbances have profound effects on the body ...
