Metabolic Acidosis: Causes, Symptoms, And Treatment
The Terrible Effects of Acid Acid corrosion is a well-known fact. Acid rain can peel the paint off of a car. Acidifying ocean water bleaches and destroys coral reefs. Acid can burn a giant hole through metal. It can also burn holes, called cavities, into your teeth. I think I've made my point. Acid, regardless of where it's at, is going to hurt. And when your body is full of acid, then it's going to destroy your fragile, soft, internal organs even more quickly than it can destroy your bony teeth and chunks of thick metal. What Is Metabolic Acidosis? The condition that fills your body with proportionately too much acid is known as metabolic acidosis. Metabolic acidosis refers to a physiological state characterized by an increase in the amount of acid produced or ingested by the body, the decreased renal excretion of acid, or bicarbonate loss from the body. Metabolism is a word that refers to a set of biochemical processes within your body that produce energy and sustain life. If these processes go haywire, due to disease, then they can cause an excess production of hydrogen (H+) ions. These ions are acidic, and therefore the level of acidity in your body increases, leading to acidem
What is INSULIN SHOCK THERAPY? What does INSULIN SHOCK THERAPY mean? INSULIN SHOCK THERAPY meaning - INSULIN SHOCK THERAPY definition - INSULIN SHOCK THERAPY explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. Insulin shock therapy or insulin coma therapy (ICT) was a form of psychiatric treatment in which patients were repeatedly injected with large doses of insulin in order to produce daily comas over several weeks. It was introduced in 1927 by Austrian-American psychiatrist Manfred Sakel and used extensively in the 1940s and 1950s, mainly for schizophrenia, before falling out of favour and being replaced by neuroleptic drugs in the 1960s. It was one of a number of physical treatments introduced into psychiatry in the first four decades of the twentieth century. These included the convulsive therapies (cardiazol/metrazol therapy and electroconvulsive therapy), deep sleep therapy and psychosurgery. Insulin coma therapy and the convulsive therapies are collectively known as the shock therapies. Insulin coma therapy was a labour-intensive treatment that required trained staff and a special unit. Patients, who were almost invariably diagnosed with schizophrenia, were selected on the basis of having a good prognosis and the physical strength to withstand an arduous treatment. There were no standard guidelines for treatment; different hospitals and psychiatrists developed their own protocols. Typically, injections were administered six days a week for about two months. The daily insulin dose was gradually increased to 100150 units until comas were produced, at which point the dose would be levelled out. Occasionally doses of up to 450 units were used. After about 50 or 60 comas, or earlier if the psychiatrist thought that maximum benefit had been achieved, the dose of insulin was rapidly reduced before treatment was stopped. Courses of up to 2 years have been documented. After the insulin injection patients would experience various symptoms of decreased blood glucose: flushing, pallor, perspiration, salivation, drowsiness or restlessness. Sopor and comaif the dose was high enoughwould follow. Each coma would last for up to an hour and be terminated by intravenous glucose. Seizures sometimes occurred before or during the coma. Many would be tossing, rolling, moaning, twitching, spasming or thrashing around. Some psychiatrists regarded seizures as therapeutic and patients were sometimes also given electroconvulsive therapy or cardiazol/metrazol convulsive therapy during the coma, or on the day of the week when they didnt have insulin treatment. When they were not in a coma, insulin coma patients were kept together in a group and given special treatment and attention; one handbook for psychiatric nurses, written by British psychiatrist Eric Cunningham Dax, instructs nurses to take their insulin patients out walking and occupy them with games and competitions, flower-picking and map-reading, etc. Patients required continuous supervision as there was a danger of hypoglycemic aftershocks after the coma. In "modified insulin therapy", used in the treatment of neurosis, patients were given lower (sub-coma) doses of insulin. A few psychiatrists (including Sakel) claimed success rates for insulin coma therapy of over 80 percent in the treatment of schizophrenia; a few others argued that it merely sped up remission in those patients who would undergo remission anyway. The consensus at the time was somewhere in between - claiming a success rate of about 50 percent in patients who had been ill for less than a year (about double the spontaneous remission rate) with no influence on relapse. Sakel suggested the therapy worked by "causing an intensification of the tonus of the parasympathetic end of the autonomic nervous system, by blockading the nerve cell, and by strengthening the anabolic force which induces the restoration of the normal function of the nerve cell and the recovery of the patient." The shock therapies in general had developed on the erroneous premise that epilepsy and schizophrenia rarely occurred in the same patient. Another theory was that patients were somehow "jolted" out of their mental illness.
Mortality And The Nature Of Metabolic Acidosis In Children With Shock
, Volume 29, Issue2 , pp 286291 | Cite as Mortality and the nature of metabolic acidosis in children with shock Mortality in children with shock is more closely related to the nature, rather than the magnitude (base deficit/excess), of a metabolic acidosis. To examine the relationship between base excess (BE), hyperlactataemia, hyperchloraemia, 'unmeasured' strong anions, and mortality. Prospective observational study set in a multi-disciplinary Paediatric Intensive Care Unit (PICU). Forty-six children, median age 6months (1.514.4), median weight 5kg (3.28.8), admitted to PICU with shock. Predicted mortality was calculated from the paediatric index of mortality (PIM) score. The pH, base excess, serum lactate, corrected chloride, and 'unmeasured' strong anions (Strong Ion Gap) were measured or calculated at admission and 24h. Observed mortality (n=16) was 35%, with a standardised mortality ratio (SMR) of 1.03 (95% CI 0.711.35). There was no significant difference in admission pH or BE between survivors and nonsurvivors. There was no association between elevation of 'unmeasured' anions and mortality, although there was a trend towards hyperchloraemia in survivors (P=0.08). Admission

The kidneys and lungs maintain the balance (proper pH level) of chemicals called acids and bases in the body. Acidosis occurs when acid builds up or when bicarbonate (a base) is lost. Acidosis is classified as either respiratory or metabolic acidosis. Respiratory acidosis develops when there is too much carbon dioxide (an acid) in the body. This type of acidosis is usually caused when the body is unable to remove enough carbon dioxide through bre ...
Content currently under development Acid-base disorders are a group of conditions characterized by changes in the concentration of hydrogen ions (H+) or bicarbonate (HCO3-), which lead to changes in the arterial blood pH. These conditions can be categorized as acidoses or alkaloses and have a respiratory or metabolic origin, depending on the cause of the imbalance. Diagnosis is made by arterial blood gas (ABG) interpretation. In the setting of me ...

Acute acid-base disorders. 2. Specific disturbances. Evaluation of the acid-base status of the body requires measurement of bicarbonate (total carbon dioxide) concentration, pH, and partial pressure of CO2 in arterial blood. Calculation of standard bicarbonate and base excess or deficit is not necessary. The normal concentration of free hydrogen ions (H+) is approximately 40 millimoles/liter, which is equivalent to a pH of 7.4. The normal load o ...
Go to: Introduction Arterial blood gas (ABG) analysis is an essential part of diagnosing and managing a patient’s oxygenation status and acid–base balance. The usefulness of this diagnostic tool is dependent on being able to correctly interpret the results. Disorders of acid–base balance can create complications in many disease states, and occasionally the abnormality may be so severe so as to become a life-threatening risk factor. A thorou ...
