Dehydration and fluid balance -
Dehydration has three categories: mild, moderate, and severe. A pediatric client with mild dehydration exhibits the following signs:. Obtain a complete history of the pediatric client from parents or caregivers.
Obtaining a complete history from the parent or caregiver is important because it provides clues to the type of dehydration present. Dehydration could be associated with hypo or hyper or isonatremia. Most cases of dehydration are hyponatremic.
In selected cases, electrolyte abnormalities may exist. This includes derangements in sodium levels, acidosis characterized by low bicarbonate levels or elevated lactate levels. For clients with vomiting who have not been able to tolerate oral fluids, hypoglycemia may be present Vega, Perform a bedside POCUS if available.
For example, the client may not be cognitively intact, able to ambulate and use both arms and hands to reach fluids and foods, and unable to swallow effectively. This may determine the assistance that the older adult may need to fulfill food and fluid intake.
Avoid relying on the results of skin turgor assessment for older adults. In most adult clients, it is useful to monitor skin turgor to detect subtle changes. However, assessment of skin turgor is not as valid in older adults because the skin has lost some of its elasticity; therefore, other assessment measures may become more useful in detecting fluid volume deficit.
Observe the fluid intake of clients with incontinence. The nurse should recognize that some older adults deliberately restrict their fluid intake to avoid embarrassing episodes of incontinence. In this situation, the nurse should identify interventions to deal with the incontinence.
Dehydration is associated with decreased secretion of bodily fluids and it is expected that small production of saliva may be an indication of deteriorating hydration status.
A small saliva pool was also reported in dehydrated older adults. Certain conditions such as Alzheimer disease are also associated with dry oral mucosa Bak et al.
Changes of consciousness have been reported by some studies and dehydration is frequently mentioned as a risk factor for delirium. However, changes in consciousness may be difficult to diagnose in older adults since many may suffer from dementia and are also susceptible to delirium due to other reasons Bak et al.
Prevention is a fundamental aspect of healthcare, and for a condition such as fluid volume deficit, proactive measures play an essential role. By focusing on prevention, the occurrence and impact of fluid volume deficit can be minimized. Through education, awareness, and proactive measures, the aim is to maintain optimal fluid balance, promote overall health, and prevent the potential complications associated with these conditions.
Provide facial skin cooling or cold compresses to the forehead and cheeks. Cooling the forehead and cheeks stimulates the trigeminal nerve , which elicits an increase in cardiac parasympathetic activity followed by a rise in sympathetic activity.
Despite the transient increase in cardiac parasympathetic activity, face cooling causes substantial increases in blood pressure that can be maintained for 15 minutes or more. Simply cooling the forehead and cheeks might be an effective intervention to maintain or improve blood pressure in hypovolemia Johnson et al.
Encourage interventions to prevent or minimize future episodes of dehydration. A client needs to understand the value of drinking extra fluid during bouts of diarrhea, fever, and other conditions causing fluid deficits. During gastroenteritis, the intestinal mucosa retains absorptive capacity.
Sodium and glucose in the correct proportions can be passively cotransported with fluid from the gut lumen into the circulation. Implement measures to prevent and manage complications associated with fluid volume deficit, such as deep vein thrombosis DVT prophylaxis, regular repositioning, and skin care.
Fluid volume deficit increases the risk of complications such as DVT and pressure injuries. Implementing preventive measures reduces the likelihood of these complications. The prognosis for clients suffering from hypovolemia depends on the underlying etiology and prompt management of the fluid status.
There is a high risk of permanent damage such as cardiac arrhythmias, cerebral hypoperfusion, and multi-organ failure if left untreated Reyes, Adequate nutrition supports overall health and helps optimize fluid balance. They can help identify foods and beverages that are hydrating and provide necessary electrolytes.
Create an emergency plan, including when to ask for help. Some complications of deficient fluid volume cannot be reversed in the home and are life-threatening. Clients progressing toward hypovolemic shock will need emergency care. Appropriate treatment usually can be initiated without delaying transport.
Encourage the client to replace fluid losses routinely. Clients should be encouraged to replace their losses to keep up with activity. Marathon runners should drink more water than non-mobile clients.
Promote the benefits of having a rotavirus vaccination. An acute condition could quickly lead to shock and will require urgent fluid resuscitation and vasopressor support.
Chronic states allow for the development of compensatory mechanisms that permit a more gradual restoration of fluid and electrolyte balance. Regardless fluid volume deficit requires prompt attention and treatment to prevent permanent organ damage and death Reyes, Control the source of bleeding.
The primary treatment of hemorrhage is to control the source of bleeding as soon as possible and to replace fluid. Encourage the client to drink bountiful amounts of fluid as tolerated or based on individual needs. A client may have restricted oral intake in an attempt to control urinary symptoms, reducing homeostatic reserves and increasing the risk of dehydration or hypovolemia.
Place a pregnant client in a left side-lying position. Avoid placing the client in a Trendelenburg position.
The Trendelenburg position is no longer recommended for hypotensive clients, as the client is predisposed to aspiration. Administer vasopressors as indicated. Vasopressors increase vasoconstriction, which leads to increased systematic vascular resistance resulting in increased mean arterial pressure and increased perfusion to the organs.
The hallmark of shock is decreased perfusion to vital organs, resulting in multiorgan dysfunction and eventually death Cardoso, Insert an IV catheter to have IV access.
Parenteral fluid replacement is indicated to prevent or treat hypovolemic complications. Two large-bore IV lines should be started in trauma clients. A short large-caliber IV catheter is ideal.
Administer fluid resuscitation as soon as possible. Crystalloid is the first fluid of choice for resuscitation. Immediately administer two liters of isotonic sodium chloride or lactated Ringer solution in response to shock from blood loss.
Administer blood products as prescribed. Blood transfusions may be required to correct fluid loss from active gastrointestinal bleeding. If vital signs return to normal, the client may be monitored to ensure stability, and blood should be sent for typing and crossmatching.
If vital signs transiently improve, the crystalloid infusion should continue, and type-specific blood obtained. Assist the healthcare provider with inserting the central venous line and arterial line, as indicated.
A central venous line allows fluids to be infused centrally and for monitoring of CVP and fluid status. An arterial line allows for the continuous monitoring of BP.
The placement of an arterial line should be considered for clients with severe hemorrhage. Apply caution when administering positive-pressure ventilation.
In the setting of hypovolemic shock, positive-pressure ventilation may diminish venous return, diminish cardiac outcome, and worsen the shock state. Provide parenteral or enteral nutrition therapy.
Increased metabolic rates during shock increase energy requirements and caloric requirements. Clients in shock may require more than calories daily.
Parenteral or enteral nutritional support should be initiated as soon as possible. Enteral nutrition is preferred, promoting GI function through direct exposure to nutrients and limiting infectious complications.
Urge the client to drink the prescribed amount of fluid. Oral fluid replacement is indicated for mild fluid deficit and is a cost-effective method for replacement treatment. Being creative in selecting fluid sources e.
Oral hydrating solutions can be considered as needed. If the client can tolerate oral fluids, give what oral fluids the client prefers.
Provide fresh water and straw at the bedside within easy reach. The type of fluid the client has lost should be considered, and fluids most likely replace the lost electrolytes are appropriate.
The client may be offered small volumes of oral rehydration solutions. These solutions provide fluid, glucose , and electrolytes in concentrations that are easily absorbed. Emphasize the importance of oral hygiene.
A fluid deficit can cause a dry, sticky mouth. Attention to mouth care promotes interest in drinking and reduces the discomfort of dry mucous membranes. If the client is reluctant to drink because of oral discomfort, the nurse assists with frequent mouth care and provides nonirritating fluids.
Provide a comfortable environment by covering the client with light sheets. Drop situations where clients can experience overheating to prevent further fluid loss. Plan daily activities.
Engaging in strenuous or physically demanding activities can lead to increased fluid loss through sweating. It is important to plan activities in a way that minimizes excessive heat exposure or intense physical exertion, which could exacerbate dehydration.
Scheduling rest periods throughout the day can help the client maintain their hydration levels and support their recovery. Provide measures to prevent excessive electrolyte loss e. Fluid losses from diarrhea should be concomitantly treated by identifying the underlying cause and providing the appropriate pharmacologic treatment.
Provide an adequate, balanced diet as soon as tolerated. Foods that contain complex carbohydrates, such as rice, wheat, potatoes, bread, and cereals are recommended, as well as lean meats, fruits, and vegetables.
Fatty foods and simple carbohydrates should be avoided. Administer oral rehydration solution appropriately.
The oral rehydration solution should be administered in small volumes very frequently to minimize gastric distention and reflex vomiting.
Generally, 5 mL of oral rehydration solution every minute is well tolerated. Administer antipyretics as ordered by the healthcare provider. Antipyretics can decrease fever and fluid losses from diaphoresis. Administer antiemetics as prescribed.
Begin to advance the diet in volume and composition once ongoing fluid losses have stopped. The addition of fluid-rich foods can enhance continued interest in eating. Administer parenteral fluids as prescribed.
Consider the need for an IV fluid challenge with an immediate infusion of fluids for clients with abnormal vital signs. Fluids are necessary to maintain hydration status.
Determination of the type and amount of fluid to be replaced and infusion rates will vary depending on clinical status. Isotonic electrolytes solutions, such as lactated Ringer solution or 0. As soon as the client becomes normotensive, a hypotonic electrolyte solution is often used to provide both electrolytes and water for renal excretion of metabolic wastes.
Administer the appropriate type of intravenous solution for severe hyponatremia. Severe hyponatremia indicates additional sodium loss in excess of water loss. Elevation of the affected area promotes venous return. Burn injuries often lead to significant swelling due to the release of fluids and inflammation.
Elevating burned extremities above the level of the heart helps minimize fluid accumulation and reduce swelling. Obtain IV access as soon as possible. In order to facilitate fluid administration, peripheral IV access may be initially obtained; however, in larger burns, central venous access is recommended due to the large volume required.
Ideally, place IV lines away from burned tissues because of the difficulty isolating veins and problems securing the IV line to the burned skin Oliver, Calculate the total body surface area and utilize the fluid resuscitation formula for fluid administration.
Total body surface area is calculated by the rule of nines, the Lund and Browder method, and the Palmar method. Administer lactated Ringer solution as appropriate.
Lactated Ringer solution is the crystalloid of choice because its pH and osmolality most closely resemble human plasma. The infusion is regulated so that one-half of the total calculated volume is given in the first eight hours post- burn injury. The second half of the calculated volume is given over the next 16 hours.
Administer hypertonic saline as indicated. Hypertonic saline solutions, ranging in concentration from to mEq per sodium per liter, have many theoretic benefits. These benefits are achieved by the reduction in volume requirements by mobilizing intracellular fluid into the vascular space by the increased osmotic gradient Oliver, Insert an indwelling catheter and nasogastric tube.
An indwelling urinary catheter is inserted to permit accurate monitoring of urine output and as a measure of kidney function and fluid needs for clients with moderate to severe burns.
All clients who are intubated should have a nasogastric tube inserted to decompress the stomach and to prevent vomiting and aspiration. Ensure that the older adult is reminded of their fluid intake frequently.
Older adult clients have a decreased sense of thirst and may need ongoing reminders to drink. Certain clients in hospitals require close observation and monitoring and fluid balance charts may provide additional support in making clinical decisions.
The charts aim to capture data on both, fluid intakes and outputs and identify individuals who are in a positive or negative balance Bak et al. Aid the client if they cannot eat without assistance, and encourage the family or SO to assist with feeding as necessary.
Dehydrated clients may be weak and unable to meet prescribed intake independently. In cases where the older adult is unable to eat solid foods but can still swallow, and oral rehydration solutions can be sued to replenish fluids and electrolytes.
Maintain IV flow rate. Stop or delay the infusion if signs of fluid overload transpire, and refer to a healthcare provider respectively. Most susceptible to fluid overload are older adult clients who require immediate attention. Increased sensitivity to fluid and electrolyte changes in older adults requires careful assessment of intake and output of fluids from all sources and prompt reporting and management of disturbances.
Administer parenteral nutrition as indicated. The goals of parenteral nutrition include improvement of nutritional status, establish a positive nitrogen balance, maintain muscle mass, promote weight maintenance or gain, and enhance the whaling process.
It is important to identify the type of shock before starting specific management because it is sometimes difficult to identify the specific shock type. Early resuscitation with prompt bleeding source control is crucial for hemorrhagic hypovolemic shock to improve survival and reduce blood product transfusion.
For non-hemorrhagic hypovolemic shock, volume resuscitation must be started as soon as possible to restore effective circulatory blood volume Taghavi et al.
A modified Trendelenburg position, also known as passive leg raising is recommended in hypovolemic shock. A full Trendelenburg position makes breathing difficult and does not increase BP or cardiac output.
Establish two large gauge IV lines. At least two large gauge IV lines are inserted to establish access for fluid administration. If an IV catheter cannot be quickly inserted, an intraosseous catheter may be used for access in the sternum, tibia, or humerus to facilitate rapid fluid replacement.
Multiple IV lines allow simultaneous administration of fluid, medications, and blood component therapy if required. Initiate fluid administration of crystalloid solutions as indicated. Crystalloid solutions such as lactated Ringer solution or 0.
If hypovolemia is primarily due to blood loss, the American College of Surgeons recommends the administration of 3 mL of crystalloid solution for each milliliter of estimated blood loss.
This is referred to as the rule. Colloid solutions such as albumin may also be used; however, hetastarch and dextran solutions are not indicated for fluid administration because these agents interfere with platelet aggregation.
Administer vasoactive medications as prescribed. If fluid administration fails to reverse hypovolemic shock, then vasoactive medications that prevent cardiac failure are given.
Medications are also given to reverse the cause of the dehydration. Insulin is given if dehydration is secondary to hyperglycemia, desmopressin is given for diabetes insipidus and antiemetic medications for vomiting.
Initiate oxygen therapy as appropriate. Oxygen is given to increase the amount of oxygen carried by available hemoglobin in the blood. Assist in placing a Sengstaken-Blakemore tube for clients with gastrointestinal bleeding.
In clients with variceal bleeding, the use of a Sengstaken-Blakemore tube can be considered. These devices have a gastric balloon and an esophageal balloon.
The gastric one is inflated first, and then the esophageal one is inflated if bleeding continues. By providing comprehensive education to clients and caregivers, nurses empower them to take an active role in preventing hypovolemia and dehydration. Education increases awareness, promotes healthy habits, facilitates early intervention, and improves overall self-care.
Client education promotes self-management and empowers the client to take an active role in maintaining a fluid balance. Clients and caregivers need to understand the importance of regular hydration and the specific fluid requirements based on age, health conditions, and environmental factors.
Educating them about the importance of consuming and adequate amount of fluids throughout the day helps prevent dehydration and maintain optimal fluid balance.
Educate the client about the risk factors and effects of fluid loss or decreased fluid intake. Enough knowledge aids the client in taking part in their plan of care.
Clients with chronic illnesses, older adults, athletes, clients on certain medications, and those exposed to high temperatures are at a higher risk. By recognizing these risk factors, clients and caregivers can take proactive measures to prevent fluid imbalances. Educate the client and family members or caregivers to identify factors that predispose the client to shock and its complications.
The client and the family are educated about strategies to prevent further episodes of shock by identifying the factors implicated in the initial episode. In addition, the client and the family require education about assessments needed to identify the complications that may occur after the client is discharged from the hospital.
Educate the client and family members about the importance of maintaining hydration and recognizing signs of fluid volume deficit. Client and family education promotes understanding of the condition, encourages adherence to fluid replacement strategies, and enables early detection of fluid volume deficit.

Every part of your body needs water to function. When you are healthy, your body is able to balance the amount of water that enters or leaves your body. A fluid imbalance may occur when you lose more water or fluid than your body can take in.
It can also occur when you take in more water or fluid than your body is able to get rid of. Your body is constantly losing water through breathing, sweating, and urinating. If you do not take in enough fluids or water, you become dehydrated.
Your body may also have a hard time getting rid of fluids. As a result, excess fluid builds up in the body. This is called fluid overload volume overload. This can lead to edema excess fluid in the skin and tissues.
Medicines can also affect fluid balance. The most common are water pills diuretics to treat blood pressure, heart failure, liver disease, or kidney disease. Contact your health care provider if you or your child has signs of dehydration or swelling, in order to prevent more serious complications.

If your child is vomiting or has diarrhea, start giving extra water or an oral rehydration solution at the first signs of illness.
Don't wait until dehydration occurs. Strenuous exercise. In general, it's best to start hydrating the day before strenuous exercise. Producing lots of clear, dilute urine is a good indication that you're well-hydrated. During the activity, replenish fluids at regular intervals and continue drinking water or other fluids after you're finished.
Hot or cold weather. You need to drink additional water in hot or humid weather to help lower your body temperature and to replace what you lose through sweating.
You may also need extra water in cold weather to combat moisture loss from dry air, particularly at higher altitudes Illness. Older adults most commonly become dehydrated during minor illnesses — such as influenza, bronchitis or bladder infections. Make sure to drink extra fluids when you're not feeling well.

In older people, the kidneys excrete excess water less efficiently, and thus older people can develop overhydration more easily than younger people do. Swelling edema may or may not occur. Dehydration can often be diagnosed from symptoms and the results of a doctor's examination.
But sometimes doctors do blood tests for people who appear seriously ill or who take certain drugs or have certain disorders. For people who require more monitoring or testing in an emergency department or intensive care unit, doctors sometimes use ultrasound or special catheters to measure the severity of dehydration.

Prevention of dehydration is better than cure. Adults should drink at least 6 glasses of fluids daily including fluid from eating foods high in water content, such as fruits and vegetables. Flavored sports drinks have been formulated to replace electrolytes lost during vigorous exercise. These drinks can be used to prevent dehydration.
People should drink fluids with electrolytes before and during vigorous exercise as well as afterward. Before exercising, people with heart or kidney disorders should consult their doctors about how to safely replace fluids.
People should make sure that older family members have access to plenty of water when they are alone in a hot building or place. For treating mild dehydration, drinking plenty of water may be all that is needed.

These solutions work well to treat dehydration, especially that caused by vomiting or diarrhea in children. Sports drinks do not necessarily contain enough electrolytes to be an adequate substitute for these solutions.
People who are vomiting may not be able to hold down enough fluid to treat dehydration. More severe dehydration requires treatment by doctors with intravenous solutions containing sodium chloride salt.

Enhance your understanding of dehydration management and ensure the delivery of quality care through this guide. Fluid volume deficit also known as hypovolemia is a state or condition where the fluid output exceeds the fluid intake. It occurs when the body loses both water and electrolytes from the ECF in similar proportions. FVD should not be confused with dehydration, however; dehydration refers to loss of water alone, with increased serum sodium levels. Fluid volume deficit results from the loss of body fluids and occurs more rapidly when coupled with decreased fluid intake.The kidneys are essential for Dehyvration the Dehydration and fluid balance gluid composition ffluid bodily fluids.

By special receptors in the hypothalamus Dehhdration are sensitive to increasing plasma osmolarity when the plasma gets too concentrated. These stimulate ADH secretion.
By stretch receptors in the atria of the heart, which are activated by abd larger than normal volume of blood returning to the heart from the veins.
These inhibit ADH secretion, because the body wants to rid itself Dehydratjon the excess fluid volume. By stretch receptors anv the aorta and carotid arteries, which are stimulated when blood pressure falls.
These stimulate ADH secretion, because the body wants to maintain enough volume to generate the blood pressure necessary to deliver blood to the tissues. In addition to regulating total volume, the osmolarity the amount of solute per unit volume of bodily fluids is also tightly regulated.
Extreme variation in osmolarity causes cells to shrink or swell, damaging or destroying cellular structure and disrupting normal cellular function. Regulation of osmolarity is achieved by balancing the intake and excretion of sodium with that of water.
Sodium is by far the major solute in extracellular fluids, so it effectively determines the osmolarity of extracellular fluids. An important concept is that regulation of osmolarity must be integrated with regulation of volume, because changes in water volume alone have diluting or concentrating effects on the fliud fluids.
For example, when you become dehydrated you lose proportionately more aand than solute sodiumso the osmolarity of your bodily fluids increases. In this situation the body must conserve water but not sodium, thus stemming the rise in osmolarity.
If you lose a large amount of blood from trauma or surgery, however, your loses of sodium and water are proportionate to the composition of bodily fluids. In this situation the body should conserve both water and sodium.
As noted above, ADH plays a role in lowering osmolarity reducing sodium concentration by increasing water reabsorption in the kidneys, thus helping to dilute bodily fluids.
To prevent osmolarity from decreasing below normal, the kidneys also have a regulated mechanism for reabsorbing sodium fluic the distal nephron. This mechanism is controlled by aldosterone, a steroid hormone produced by the adrenal cortex. Aldosterone secretion is controlled two ways:.
The adrenal cortex directly senses plasma osmolarity. When the osmolarity increases above normal, aldosterone secretion is inhibited.
The lack of aldosterone causes less sodium to be reabsorbed in the distal tubule. Remember that bqlance this setting ADH secretion will increase to conserve water, thus complementing the effect of low aldosterone levels to decrease the osmolarity of bodily fluids.
Fkuid net effect on urine excretion is a decrease in the amount of urine excreted, with an increase in the osmolarity of the urine. The kidneys sense low blood pressure which results in lower filtration rates and lower flow through the tubule.
This triggers a complex response to raise blood pressure and conserve volume. Specialized cells juxtaglomerular cells in the afferent and efferent arterioles produce renina peptide hormone that initiates a hormonal cascade that ultimately produces angiotensin II. Angiotensin II stimulates the adrenal cortex to produce aldosterone.
Anv aldosterone is also acting to increase sodium reabsorption, the net effect is retention of fluid that is roughly the same osmolarity as bodily fluids. The net effect on urine excretion is a decrease in the amount of urine excreted, with lower osmolarity than in the previous example.
