Felt, MD. Get Citation Citation. Updates available for this chapter. Evaluating and managing fluid and electrolyte disorders in children requires an understanding of the composition of the human body and the regulatory mechanisms that maintain homeostasis. The primary care physician will encounter the issue of managing fluids and electrolytes in a large number of patients. The optimal fluid and electrolyte solution varies depending on the age of the patient, cause of the disease, severity of the condition, and presence of a coexisting morbidity in the patient.
Normal homeostasis is maintained by a complex interaction among the solutes, body water, hormonal influence, and the hypothalamic-pituitary-renal axis. Guiding the approach to fluid therapy in any child are a few basic principles of human physiology, including the regulation of body water, electrolytes, and acid-base equilibrium.

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. The diagnosis of the acid-base disorder should proceed in a stepwise fashion as emphasized in the text see Chap.

Fluids and electrolytes are basic components of the human body and essential for the survival of most species. Any imbalance can potentially lead to serious conditions and death. The replacement of fluids and electrolytes has been used since the ancient age. Modern medicine still requires certain degree of expertise in these areas, which ranges from simple replacement in patients with mild illness to a more complex management in critically ill or hospitalized patients. Severe sodium abnormalities are associated with increased morbidity and mortality, and they are markers of poor outcomes. This review presents a concise discussion of frequently asked questions in the evaluation and management of patients with fluids and sodium abnormalities.
Fluid and electrolyte balance is a key concept to understand for maintaining homeostasis, and for a successful treatment of many metabolic disorders. There are various regulating mechanisms for the equilibrium of electrolytes in organisms. Disorders of these mechanisms result in electrolyte imbalances that may be life-threatening clinical conditions. In this study we defined the electrolyte imbalance characteristics of patients admitted to our emergency department. All patients had electrolyte imbalance, with various etiologies other than traumatic origin. Demographic and clinical parameters were collected after obtaining informed consent from the patients.

Shepherd A Measuring and managing fluid balance. Nursing Times; 28, early online publication. This article discusses the importance of hydration, and the health implications of dehydration and overhydration. It also provides an overview of fluid balance, including how and why it should be measured, and discusses the importance of accurate fluid balance measurements. Water is essential for life, and maintaining the correct balance of fluid in the body is crucial to health Welch, However, according to a recent report from the Care Quality Commission , some hospital patients are not being given enough water to drink. The report suggests fluids are being left out of reach, or are not being given at all for long periods.
Enteral fluid therapy in neonatal calves and features of commercially available electrolyte solutions in Brazil. According to the World Health Organization, the development of orally replacement fluids and electrolytes was one of the most significant advances of the twentieth century, markedly reducing mortality from diarrheal children. In veterinary medicine, oral electrolyte solutions OES are routinely used to treat diarrheic neonatal calves in order to correct water, electrolyte and acid base imbalances.
Acidosis and alkalosis describe the abnormal conditions that result from an imbalance in the pH of the blood caused by an excess of acid or alkali base. This imbalance is typically caused by some underlying condition or disease. Normal blood pH must be maintained within a narrow range, typically 7. Acidosis refers to an excess of acid in the blood that causes the pH to fall below 7. Many conditions and diseases can interfere with pH control in the body and cause a person's blood pH to fall outside of healthy limits.
Acid-base disturbances are physiological responses to a wide variety of underlying conditions and critical illnesses. Homeostasis of acid-base physiology is complex and interdependent with the function of the lungs, kidneys, and endogenous buffer systems. Traditionally, these disturbances have been classified in terms of being caused by either a primary respiratory or a metabolic insult and by chronicity and compensation. While existing literature consists largely of physiology reviews, several well-designed studies and clinical practice guidelines provide relevant new perspectives on interpreting and managing acid-base disturbances. This review outlines several approaches to characterizing disturbances, with a case-based format and algorithms to aid in diagnostic testing and interpretation of arterial blood gases.
