Admitting Orders for 1-Year-Old with Moderate Dehydration

For this 8.3kg child with moderate dehydration from fever and vomiting, initiate oral rehydration therapy with 830mL of low-osmolarity ORS (100 mL/kg) administered over 3-4 hours, with nasogastric administration if oral intake is refused or not tolerated. 1

Initial Assessment and Documentation

  • Document baseline weight (8.3kg) immediately - this is mandatory before initiating treatment and serves as the most accurate assessment of fluid status 2
  • Assess dehydration severity using clinical signs: skin turgor (prolonged tenting >2 seconds), perfusion status (capillary refill, extremity temperature), mental status, and respiratory pattern 2
  • Moderate dehydration (6-9% fluid deficit) is characterized by loss of skin turgor, tenting of skin when pinched, and dry mucous membranes 2

Rehydration Phase Orders

Primary Rehydration Strategy

  • Administer low-osmolarity oral rehydration solution (ORS): 830mL total over 3-4 hours (calculated as 100 mL/kg for moderate dehydration) 1
  • Acceptable commercial formulations include Pedialyte, CeraLyte, or Enfalac Lytren 1
  • Do NOT use apple juice, Gatorade, or commercial soft drinks - these are inappropriate for rehydration 1, 3

If Oral Intake Not Tolerated

  • Nasogastric ORS administration at 125 mL/hour (15 mL/kg/hour for this 8.3kg infant) if the child refuses to drink adequately or cannot tolerate oral intake 4
  • For vomiting: administer small, frequent volumes (teaspoonful every 1-2 minutes) to improve tolerance 3
  • Consider ondansetron (if >4 years old per guidelines, though this patient is 1 year) to facilitate oral rehydration tolerance 1, 5

Escalation Criteria to IV Therapy

  • Switch to IV isotonic fluids (lactated Ringer's or normal saline) if:
    • ORS therapy fails after adequate trial 1
    • Signs of severe dehydration develop (altered mental status, shock, poor perfusion) 1
    • Persistent severe vomiting prevents oral/NG intake 1
    • Ileus develops 1
  • IV bolus: 20 mL/kg (166mL for this child) until pulse, perfusion, and mental status normalize 2

Maintenance Phase Orders

Once Rehydration Complete (After 3-4 Hours)

  • Reassess hydration status - check weight, clinical signs, urine output 4
  • Resume age-appropriate normal diet immediately - do not delay feeding 1
  • Continue breastfeeding if applicable throughout the illness 1
  • Replace ongoing losses: 60-120 mL ORS for each diarrheal stool or vomiting episode (for <10kg body weight), up to ~500 mL/day 1

Monitoring Orders

  • Vital signs every 2-4 hours initially 4
  • Strict intake and output documentation 4
  • Daily weights 2
  • Monitor for signs of worsening: continued high stool output, persistent thirst, fever, altered mental status 4

Nutritional Orders

  • Resume regular diet as soon as rehydration is complete - this shortens the duration of diarrhea 1, 3
  • If formula-fed, continue regular lactose-containing formula (diluted formula offers no benefit) 1
  • If breastfed, continue nursing throughout illness 1

Medications to AVOID

  • No antimotility drugs (loperamide) - contraindicated in children <18 years with acute diarrhea 1
  • Antidiarrheal drugs do not prevent dehydration and should not be used 3

Discharge Criteria

  • Successfully tolerated at least 25 mL/kg of ORS (approximately 200mL for this child) during observation period 6
  • Adequate urine output documented 7
  • Weight gain achieved 7
  • No severe emesis (>5 mL/kg) 7
  • Improved clinical dehydration signs 7
  • Caregiver demonstrates understanding of home ORS administration 3

Common Pitfalls to Avoid

  • Do not rely solely on sunken fontanelle or absence of tears - these are less reliable indicators of dehydration 2
  • Do not rush to IV therapy - ORT is as effective as IV rehydration for moderate dehydration and has lower complication rates 1, 7
  • Do not withhold feeding - early refeeding shortens illness duration 1, 3
  • Capillary refill can be misleading in the presence of fever or in very young infants 2
