Nr 1: Mehr als 7 Millionen monatliche Besucher und 8.100 Verkäufer vertrauen uns bereit One of the primary objectives of maintenance parenteral fluid therapy is to provide water to meet physiologic losses (insensible loss + urine loss). this formula has been further simplified, with the hourly requirement referred to as the 4-2-1 rule (4 mL/kg/hr for the first 10 kg of weight, 2 mL/kg/hr for the next 10 kg, and 1 mL/kg. Maintenance intravenous fluids (IVFs) are used to provide critical supportive care for children who are acutely ill they should only be administered when clinically indicated. (Feld et al.) Prehospital providers are drilled with the standard PALS formula for fluid resuscitation, 20ml/kg, or 10ml/kg for infants
Even though it is correct to think about fluid requirements on a 24-hour basis, the delivery pumps used in hospitals are designed to be programmed for an hourly infusion rate. The 24-hour number is often divided into approximate hourly rates for convenience, leading to the 4-2-1 formula. 100 ml/kg/24-hours = 4 ml/kg/hr for the 1st 10 k Rate of crystalloid per hour=. 4mL/kg for first 10kg (40) +2mL/kg for next 10kg (+20) +1mL/kg for every next kg (+ (wt - 20 kg)) E.g. 110 mL/hr for a 70 kg pt. N.b. Pediatric fluid bolus is 20mL/kg. Pediatric blood transfusion dose is 10cc/kg. Rates extrapolated for high mass (adults) may be inadequate, always titrate fluids based on patient. 2) 4 - 2 - 1 rule: First 10 kg with 4 mL/hr, the following 10 kg with 2 mL/hr and the rest of 6 kg with 1 mL/hr = 10 x 4 + 10 x 2 + 6 = 66 mL/hr. Maintenance fluid therapy. Fluid therapy is instituted in order to preserve the normal volume of body fluids and their electrolyte composition
Malcolm Holliday, MD, (d. 2014) was a pediatric nephrologist and physiologist. Dr. Holliday's original work studying inherited tubular disorders and congenital renal defects eventually led him to become professor of pediatrics and chief of the Division of Pediatric Nephrology at University of California San Francisco, a position he held for over two and a half decades of his 60 year career Calculating the maintenance for adults is usually quite easy. As long as the patient is over 60 kg, just add 40 ml to the weight. You can do the 4-2-1 Rule in these cases too - the math all works out the same. So, if the patient had been NPO for 12 hours, they would need 984 ml of fluid to get caught up (82 ml x 12 hours) Step 1: Calculate Preoperative Fluid Losses. Simply multiply the maintenance fluid requirements (cc/hr) times the amount of time since the patient took PO intake. Estimated maintenance requirements follow the 4/2/1 rule: 4 cc/kg/hr for the first 10 kg, 2 cc/kg/hr for the second 10 kg, and 1 cc/kg/hr for every kg above 20 Jul 10, 2007. #3. The 421 rule is used to calcuate the hourly infusion rate for maintenance fluids (generally just for pediatrics). 4 cc/hr for kg 1-10. 2 cc/hr for kg 11-30. 1 cc/hr for each additional kg. So for a 70-kg male, the infusion rate would be 40 + 40 + 40 = 120 cc/hr. This is similar to the daily requirement method
IV Maintenance Fluids Calculator. Determines the pediatric fluid requirement based on the Holliday-Segar Nomogram and the 4-2-1 rule. More information about the two formulas and about maintenance fluid therapy, can be found in the text below the form. The IV maintenance fluid calculator is a tool addressed to clinicians that need to determine. Calculating the Maintenance Fluid Rate The 4-2-1 rule is routinely used to calculate the maintenance ﬂuid rate for children. The formula states that for the ﬁrst 10 kg of body weight, 4 mL of ﬂuid are administered per kg, per hour. For the second 10 kg, 2 mL/kg/hr are administered, and for each additional kg over 20 kg, 1 mL To calculate the 8hrs period maintenance fluid, convert daily maintenance to hourly maintenance, and multiply the result by 8. = 366.64 (approx. 367ml). Using the 4-2-1 rule, calculate the hourly maintenance fluid for a sick child weighing 25kg. Daily maintenance fluid for this child= 65ml*24= 1560ml per day Aim: Traditional paediatric intravenous maintenance fluids are prescribed using hypotonic fluids and the weight-based 4:2:1 formula for administration rate. However, this may cause hyponatraemia in sick and post-operative children. We studied the effect of two types of intravenous maintenance fluid and two administration rates on plasma sodium concentration in intensive care patients A 3-month-old infant has much different fluid needs than those of a more fully grown 8-year-old child. In many cases, a simple calculation called the 4-2-1 rule can determine the hourly rate of fluid maintenance required for a child based on weight. The following example shows an application of this formula
o Extracellular fluid losses (e.g. GI losses) = most similar to 500ml 0.9% saline with 13.5mmol KCl o Fever = same type of fluids as normal maintenance fluids (500ml 0.9% saline+5% dextrose with 10mmol KCl) If patient is on maintenance fluids and requires extra to correct losses/deficit you can quantify extra fluids as maintenance + 5/10/15 Maintenance fluids are given over 24 hours and calculated by the weight using the Holliday-Segar formula for children >28 days of age, or by weight and age in neonates. Replacement fluids are required where there is an existing fluid deficit and evidence of clinical dehydration on examination

Maintenance IV fluids for these patients will not be written with the standard formula because thier urinary losses are not taking place at a normal rate. Maitenance fluids using the standard formula would be too much for an anuric child with no urinary losses and too little for those with a concentrating defect in thier kidneys causing polyuria Recommended maintenance fluid rates (mL/kg/hr)49. Cats. Dogs. Formula: 80 x body weight (kg) 0.75. Formula: 132 x body weight (kg) 0.75. Rule of thumb: 2-3 mL/kg/hr. Rule of thumb: 2-6 mL/kg/hr. Whether administered either during anesthesia or to a sick patient, fluid therapy often begins with the maintenance rate, which is the amount of.
Maintenance amount (4-2-1 formula): Maintenance fluid volume determined based on patient weight, and the classical calculation of maintenance fluid requirement using the 4-2-1 rule was adopted from Holliday and Segar's in 1957 (7,8). And with calculation of electrolytes in breast milk, they add 0. The following 4:2:1 formula is used to rapidly calculate a child's maintenance fluid requirements: For example, a 12 kg child would require: (4 x 10 kg) + (2 x 2 kg) = 44 mL/kg/hr of maintenance fluid These two IV solutions are also the primary IV solutions of choice to provide for hourly maintenance fluid requirements in neonates and very young infants (< 4-6 months). Hourly Fluid Requirements calculated based on the 4-2-1 Rule provide the minimum 5mg/kg/min of glucose needed by the infant brain. Neonates have excess total body water (TBW.

Hydraulic oil ranks high among fluids with multi-function capability. True, for sheer utility, it can't match olive oil, which through the centuries has been used as food, lubricant, fuel, medicine, and in religious rites. But, hydraulic oil does serve as an energy-transmission medium, heat-transfer medium, sealant, and lubricant as it powers buckets, blades, and breakers, for example, or. The basic strategy for managing the patient with oliguria is to provide maintenance fluids at a rate that replaces insensible losses (typically 1/3 of maintenance in children less than 20 kg and 1. The widely used formula for calculating this rate (the 4-2-1 rule) was developed in 1957 and was popularized as much for simplicity as for accuracy. Its original proponents utilized a rough estimate of patient energy requirements to extrapolate fluid needs, escalating stepwise with increases in weight, to arrive at the 4-2-1. Holliday segar method is a widely acceptable method of calculating maintenance fluid, especially in children. It helps to estimate the fluid requirement in 24 hours. The method is based on the weight of patient in kilogram. This formula relates water loss to the caloric expenditure Crystalloid fluids are a subset of intravenous solutions that are frequently used in the clinical setting. Crystalloid fluids are the first choice for fluid resuscitation in the presence of hypovolemia, hemorrhage, sepsis, and dehydration. Further clinical applications include acting as a solution for intravenous medication delivery, to deliver maintenance fluid in patients with limited or no.

Most enteral formulas contain 80-85% free water, and fluid needs can be met with a small amount of additional water.However, calorically dense formulas contain as little as 60% free water, so the failure to supplement water with the denser formulas can result in dehydration Enter weight of patient to calculate maintenance fluid rate. Assessment. If clinically dehydrated, estimate percentage dehydration and the calculator will incorporate fluid deficit into calculations. See Gastroenteritis guideline. Management. Nursing. Print/PDF of this guideline. Related guidelines. Diabetic Ketoacidosis - Fluid Calculator. Fluid therapy is a topic that sometimes gets overlooked by veterinarians, partly because there is a misconception that developing fluid plans can be very difficult. However, if you keep it simple, you can develop a tailored fluid therapy plan for you patient that is much better than a blanket 'twice maintenance' rate

Different hospitals may have different policies, but for learning how to perform these pediatric dosage calculations, the following commonly used table of fluid requirements may be used restricting fluids to 50-80% of routine maintenance needs or reducing fluids, calculated on the basis of insensible losses within the range 300-400 ml/m 2 /24 hours plus urinary output Base any subsequent IV fluid prescriptions on the plasma electrolyte concentrations and blood glucose measurements No Yes Yes *For term neonates up t
Another standard formula often used is 60mL/kg/day for maintenance fluids. For the 40-kg dog: 60 mL X 40 kg = 2400 /24 hours = 100 mL/hr While there are variations in fluid rate calculations, the fluid rate should always be determined based on the hydratio fluids in older children. the maintenance fluid requirements of older children are also based on ml/kg/day. 1-10 kg: 100 ml/kg/d. 11-20 kg: 1000 ml + 50 ml/kg above 10 kg/d. 21-30 kg: 1500 ml + 20 ml/kg above 20 kg/d. > 30 kg: 1700 ml + 10 ml/kg above 30 kg/d. another way to remember this (also known as the 4/2/1 rule)

Assess for three types of fluid disturbances Their formula for IV fluid resuscitation used equal parts of plasma and saline and prescribed 150 ml of fluid for each 1% TBSA burn plus maintenance fluids during the first 24 h following injury . Half of this fluid is given over the first 8 h, and the second half of the fluid is administered over the next 16 h (see Table 1 ) 1. Maintenance IV fluid until patient taking adequate oral intake. B. TBSA ≥ 20% and Weight ≥ 30 kg 1. Calculate estimated intravenous fluid needs: a. 2‐4 mL of LR x kg body weight x %TBSA burn b. Administer half of calculated volume over the firs
Based on these facts, we propose a new equation for the maintenance fluid volume for hospitalized children. Our equation (300 × W 1/2 mL/day) gives values almost equal to the maintenance fluid volume calculated by the most commonly used equation of Holliday and Segar in children aged 2-18 years Because of this, pediatric burn resuscitation formulas are always 2-figure calculations: the estimated fluid resuscitation (EFR) and added maintenance fluids (MF) with or without dextrose depending on the child's age. The cutoff for using the adult formula is generally agreed to be between 30 to 50 kg
nous maintenance fluids. Is this because of excessive water or too little salt? Moritz and Ayus discussed the high frequency of hyponatraemia in these children in their paper in Pediatrics in February 2003.1 They suggested the use of isotonic saline rather than use of hypotonic fluids for maintenance therapy. More than 20 years ago ther The osmolarity and tonicity of a solution are not the same thing! Administering solutions with inappropriate tonicity can lead to life-threatening fluid and electrolyte imbalances. [7] The osmolarity of a parenteral solution takes into account the concentration of all the solutes, including those that enter cells (e.g., dextrose). The tonicity of a solution is determined by the solutes that do.
Maintenance therapy is needed to cover insensible losses and urine output (from the beginning of preoperative fasting), and current evidence suggests that maintenance fluid requirements should be met with a basal crystalloid infusion rate of 1 to 1.5 ml · kg −1 · h −1; more is needed for major surgeries associated with large fluid shifts a) potential dialysis safety/fluid -weight management related measures such as those germane to rapidity or magnitude of fluid removal at dialysis, e.g.: • ultrafiltration rate • length of hemodialysis sessions • frequency of intradialytic hypotension • interdialytic weight gai The 24-Hour Fluid Calculation Formula is the most accurate method to calculate fluid requirements. For practical reasons, you may use the 4-2-1 Rule to obtain an estimate of fluid requirements per hour Step 1: Maintenance Fluids Calculation in mL/hr Formula: 1. First 10 kg = 4 mL/kg/hr 2. Second 10 kg = 2 mL/kg/hr 3. Remaining kg = 1 mL/kg/hr Example: • 5 kg child = 5 kg x 4 mL= 20 mL/hr OR • 29 kg child = 10 kg x 4 mL= 40 mL/hr PLUS 10 kg x 2 mL= 20 mL/hr PLUS 9 kg x 1 mL= 9 mL/hr Total = 69 mL/hr Step 2: Tubing Siz Maintenance fluid is the amount of fluid the body needs to replace usual daily losses from the respiratory tract, the skin and the urinary and gastrointestinal (GI) tracts. A well child usually drinks more than maintenance requirements. If a child takes in significantly less than maintenance requirements, he or she will gradually become dehydrated
Fluid management must be individualized. Additional parameters for fluid management include urine output & systemic blood pressure. The 24 hour formula is: fluids for 24 hours = 4 × kg × % burn (2 nd & 3 rd added together) with 1 st 50% of that total in the first 8 hours and the 2 nd 50% over the following 16 hours. Helpful diagrams 1 Acceptable ranges for maintenance sodium and potassium/100 ml of maintenance fluids/day: Sodium = 2.5 - 3.0 mEq; Potassium = 2.0 - 3.0 mEq 2 + Subtract the pure free water deficit from the total deficit before proceeding to calculate the isotonic Na an 40 mL/hr + 2 mL/kg/hr. ≥ 21 kg. 60 mL/hr + 1 mL/kg/hr. For a child who weighs 42 pounds, the correct IV drip rate for fluid maintenance is how many mL/hr? First, find the child's weight: 42/2.2 = 19.09, rounded to 19 kg. Next, identify the correct formula: (4 mL X10 kg) + (2mL x 9kg) = hourly rate. 40 mL + 18 mL = 58 mL/hr Finally, add all the values to get your total fluid maintenance needs for this child: 1000 + 500 + 500 + = 2000 mL/day. Simple, right?! CALORIC INTAKE. Daily caloric intake is a simple calculation. It is important to know how many calories in one ounce, how many ounces of formula in one bottle and how bottles consumed in 24 hours Table 1: Hourly Maintenance Fluid Requirements (1-hour periods) Calculation: 4 mL/kg/hour for first 10 kg of body weight. + 2 mL/kg/hour for the next 10 kg of body weight (over the initial 10 kg of body weight) + 1 mL/kg/hour for each kilogram over 20 kg of body weight. Maximum of 100 mL/hour or 2400 mL a day needed for maintenance

Neonates (up to 44 weeks post-conceptual age) have different requirements. They are born physiologically waterlogged then lose this fluid over the first week of life For patients under 5 kg and over 40 kg, we should calculate their true fluid needs with the help of a maintenance chart or the following formula: 70 x (weight in kg) to the power 0.75. This sounds complicated. How do you figure that out easily? A cheap calculator with a square root function is all you need
Routine maintenance fluids. If a patient is haemodynamically stable but unable to meet their daily fluid requirements via oral or enteral routes you will need to prescribe maintenance fluids. If possible these fluids should be administered during daytime hours to prevent sleep disturbance. Calculating maintenance fluids Formula: IV fluid replacement for NPO deficit. 2 mL × W × H. W = Weight in kilograms (kg) H = Hours; IV fluid replacement for NPO deficit = 2 milliliter/kilogram (2mL/kg) for each hour NPO prior to surgery. Replace 50% of deficit within the first hour of surgery with the remaining 50% being replaced over the next 2 hours Fluids for Sepsis Guidance from the Surviving Sepsis Campaign 2016 • The recommendation, for the initial fluid resuscitation from sepsis-induced hypoperfusion, is to infuse at least 30 mL/kg of intravenous crystalloid fluid within the first three hours. • Fluids should be administered for hypotension, lactate ≥ 4 mmol/L or septic shock The formula used for calculating the volume of required maintenance fluid and electrolyte. It is calculated based on the body weight to only represent the empiric average caloric expenditure. The first 10 kg of body weight accounts for 100 kcal/kg/day or equals to 100 mL/kg of maintenance fluid

FLUID RESUSCITATION. Pre-Hospital Fluid Rate for Larger Burns (>15% TBSA), since they don't have pumps and only have drip sets. Infants: 20 drops/minute Pediatrics: 40 drops/minute Adults: 80 drops/minute Rule of 10's for initial fluid rate, adults only. Estimate burn size to the nearest 10 TBSA x 10 = initial rate in m/h (fo If the child is isonatremic (130-150 mEq/L), the sodium deficit incurred can generally be corrected by administering the remaining fluid deficit after phase 1 plus maintenance as 5% dextrose in 0. When estimating the volume of fluid needed by a patient, the veterinarian should consider not only the deficit, but also maintenance requirements (50 to 100 ml/kg) and compensation for continuing loss (as much as 4 L in 24 hours)
