Electrolyte imbalance

Written and peer-reviewed by physicians—but use at your own risk. Read our disclaimer. 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 metabolic acidosis , calculation of the anion gap is an important resource to narrow down the possible causes and reach a precise diagnosis. Treatment is based on identifying the underlying cause. Start with an ABG and then proceed in the following order:.

Your blood needs the right balance of acidic and basic alkaline compounds to function properly. This is called the acid-base balance. Your kidneys and lungs work to maintain the acid-base balance. Even slight variations from the normal range can have significant effects on your vital organs. Acid and alkaline levels are measured on a pH scale. An increase in acidity causes pH levels to fall.

A year-old woman was admitted with a 3-day history of fever, cough productive of blood-tinged sputum, confusion, and orthostasis. Past medical history included type 1 diabetes mellitus DM. A physical examination in the emergency department indicated postural hypotension, tachycardia, and Kussmaul respiration.

Overview of acid-base and electrolyte disorders

Metrics details. In clinical practice, both the history and laboratory testing are paramount to making an accurate diagnosis. Situations in which laboratory findings and patient history are not congruent pose a diagnostic dilemma. We report a case of a young woman presenting with a myriad of electrolyte and acid-base disorders. Difficulty in reaching a unifying diagnosis persisted due to discordant patient history. We believe this case shows that lab findings will clearly portray the problems a patient has and should be given more credence in a case where the history is discordant with lab findings. A year-old Hispanic American woman presented to the emergency room of our institution with a complaint of painless and sudden onset of stiffness in her upper and lower limbs.

Electrolyte imbalance , or water-electrolyte imbalance , is an abnormality in the concentration of electrolytes in the body. Electrolytes play a vital role in maintaining homeostasis in the body. They help to regulate heart and neurological function, fluid balance , oxygen delivery , acid—base balance and much more. Electrolyte imbalances can develop by consuming too little or too much electrolyte as well as excreting too little or too much electrolyte. Electrolyte disturbances are involved in many disease processes, and are an important part of patient management in medicine. Other electrolyte imbalances are less common and often occur in conjunction with major electrolyte changes.

Fluids and Electrolyte Management, Part 2

Disorders of blood chemistry may be caused by dietary factors, underlying medical conditions, and medical treatments. Electrolyte balance is normally regulated by the hypothalamus, kidneys, and various hormones, including antidiuretic hormone ADH , aldosterone a mineralocorticoid hormone , and parathyroid hormone PTH. Acid-base balance is linked to fluid and electrolyte balance, and is normally controlled and maintained by immediate buffer systems via the kidneys and the pulmonary system.

As part of routine health screening or when your healthcare practitioner suspects that you have an imbalance of one of the electrolytes usually sodium or potassium or an acid-base imbalance. You may be able to find your test results on your laboratory's website or patient portal. However, you are currently at Lab Tests Online.

Approach to fluid and electrolyte disorders and acid-base problems

Mohammed Al-Jaghbeer, John A. Acid—base disturbances are very common in critically ill and injured patients as well as contribute significantly to morbidity and mortality. An understanding of the pathophysiology of these disorders is vital to their proper management. This review will discuss the etiology, pathophysiology and treatment of acid—base disturbances in intensive care patients—with particular attention to evidence from recent studies examining the effects of fluid resuscitation on acid—base and its consequences.

Шаги приближались. Он услышал дыхание. Щелчок взведенного курка. - Adids, - прошептал человек и бросился на него подобно пантере.


Он смотрел на девушку, понимая, что его поиски подошли к концу. Она вымыла голову и переоделась - быть может, считая, что так легче будет продать кольцо, - но в Нью-Йорк не улетела. Беккер с трудом сдерживал волнение. Его безумная поездка вот-вот закончится. Он посмотрел на ее пальцы, но не увидел никакого кольца и перевел взгляд на сумку. Вот где кольцо! - подумал .

Я хотел бы с ней покувыркаться. Ролдан сразу решил, что это подстава. Если он скажет да, его подвергнут большому штрафу, да к тому же заставят предоставить одну из лучших сопровождающих полицейскому комиссару на весь уик-энд за здорово живешь. Когда Ролдан заговорил, голос его звучал уже не так любезно, как прежде: - Сэр, это Агентство услуг сопровождения Белен.

Разумеется. Но мне она неизвестна. - Видите ли, ситуация не столь проста.

Старик внимательно разглядывал подозрительного посетителя. Беккер перешел чуть ли не на шепот: - Я здесь, чтобы узнать, не нужно ли вам чего-нибудь.  - Скажем, принести пару таблеток валиума. Наконец канадец опомнился. - Из консульства? - Его тон заметно смягчился.

    Step 2: Examine the serum chloride concentration. One should always examine the serum chloride concentration with re- spect to the serum sodium concentration. Step 3: Calculate the anion gap. Step 4: Is the measured HCO3. Step 5: Interpret the arterial blood gas. Step 6: Examine serum potassium concentration.

    Employing a systematic approach to the interpretation of serum chemistries is the most effective way to ensure abnormalities are detected and correctly.
