Fluid Management and Nutrition Guidelines

Base Fluid Requirements

The European Society for Clinical Nutrition and Metabolism suggests a base fluid requirement of 1-4 ml/kg/hour of isotonic crystalloid (typically 0.9% NaCl or Ringer's lactate) 1
The American Diabetes Association recommends potassium levels of 20-30 mEq/L in maintenance fluids once renal function is confirmed 2

The Holliday-Segar formula calculates fluid requirements as 100 ml/kg/day for the first 10 kg, 50 ml/kg/day for the next 10 kg, and 20 ml/kg/day for each kg above 20 kg 3

The American Diabetes Association recommends sodium and potassium levels of 20-40 mEq/L (2/3 KCl and 1/3 KPO₄) for children 2
The European Society for Clinical Nutrition and Metabolism suggests chloride levels slightly lower than the sum of sodium and potassium (Na + K - Cl = 1-2 mmol/kg/day) 3
Corrected serum sodium should be used to guide fluid selection, with normal/high corrected sodium requiring 0.45% NaCl and low corrected sodium requiring 0.9% NaCl 2

The Society of Critical Care Medicine recommends assessing vital signs, urine output, and clinical examination several times daily to monitor for fluid overload 4
The American Diabetes Association suggests watching for signs of fluid overload such as crepitations, increased work of breathing, or peripheral edema 2
The European Society for Clinical Nutrition and Metabolism recommends reducing fluid rates if signs of overload appear and adjusting for ongoing losses such as fever, drains, or gastrointestinal losses 1

Ensure adequate nutrition is provided through alternative routes when patients are NPO, with a strength of evidence of high quality 5
Nutritional compromise can occur within 2-3 weeks if adequate nutrition is not provided, with a strength of evidence of moderate quality 5
For NPO diabetic patients, the American Diabetes Association recommends basal insulin or a basal plus bolus correction insulin regimen as the preferred treatment, with a strength of evidence of high quality 5
Sliding scale insulin alone (without basal insulin) is discouraged for NPO diabetic patients, with a strength of evidence of moderate quality 5
Blood glucose monitoring should be performed every 4-6 hours in patients who are not eating, with a strength of evidence of high quality 6

A formal swallowing assessment should be completed before resuming oral intake, with a strength of evidence of high quality 5, 7, 8
Swallowing screening should be completed within 24 hours of hospital arrival, with a strength of evidence of moderate quality 8
The following practices should be avoided:
The following table summarizes the recommendations for swallowing assessment and management:

Recommendation	Strength of Evidence
Formal swallowing assessment before resuming oral intake	High quality [5, 7, 8]
Swallowing screening within 24 hours of hospital arrival	Moderate quality [8]
Avoid administering oral medications without swallowing assessment	High quality [7, 8]
Avoid discontinuing tube feeds without ensuring alternative nutrition is safely established	Moderate quality [9]
Avoid assuming a negative CT brain scan means swallowing function is intact	Moderate quality [7, 8]
Avoid delaying swallowing assessment	Moderate quality [8]

The American College of Rheumatology recommends intra-articular injection of corticosteroids for involvement of 1-2 joints, with a strength of evidence of moderate quality 10
Intravenous or intramuscular methylprednisolone at an initial dose of 0.5-2.0 mg/kg is appropriate for NPO patients with acute gout, with a strength of evidence of moderate quality 10
Subcutaneous synthetic adrenocorticotropic hormone (ACTH) at an initial dose of 25-40 IU is an alternative for NPO patients with acute gout, with a strength of evidence of low quality 10
