What is the initial treatment approach for a 5-year-old child with ileus?

Treatment for Ileus in a 5-Year-Old Child

Initiate intravenous isotonic fluids (lactated Ringer's or normal saline) immediately and maintain bowel rest until ileus resolves. 1, 2

Initial Management

Intravenous fluid resuscitation is the cornerstone of treatment:

• Administer isotonic IV fluids such as lactated Ringer's solution or normal saline 1, 2
• Continue IV rehydration until pulse, perfusion, and mental status normalize and there is no evidence of ileus 1, 2
• Oral rehydration solutions are contraindicated in the presence of ileus 1

The Infectious Diseases Society of America provides strong evidence (moderate quality) that isotonic IV fluids must be used when ileus is present, as oral rehydration therapy fails in this setting and can worsen abdominal distention. 1

Nasogastric Decompression

Consider nasogastric tube placement if:

• Severe abdominal distention is present 2
• The child is vomiting repeatedly 2
• Risk of aspiration exists 2

This intervention helps decompress the bowel and prevents aspiration, though routine prophylactic NG tube placement should be avoided as it may prolong ileus duration. 2

Supportive Care Measures

Maintain strict NPO (nothing by mouth) status:

• No oral intake until bowel function returns 2
• Once ileus resolves, resume oral intake gradually starting with clear liquids and advance as tolerated 2

Correct electrolyte abnormalities:

• Monitor and replace potassium, sodium, and other electrolytes as needed 3
• Check serum electrolytes if clinical signs suggest abnormalities 1

Discontinue contributing medications:

• Stop any antimotility agents (loperamide should never be used in children with ileus) 1, 4
• Avoid anticholinergic, antidiarrheal, and opioid agents as they aggravate ileus 2

Monitoring and Reassessment

Clinical monitoring should include:

• Serial abdominal examinations for distention, bowel sounds, and tenderness 3
• Vital signs monitoring (pulse, perfusion, mental status) 1
• Assessment for return of bowel function (passage of flatus or stool) 2
• Watch for complications including bowel perforation, increased intra-abdominal pressure, and abdominal compartment syndrome 5

Special Considerations for Pediatric Patients

A 5-year-old child requires weight-based fluid calculations:

• For a child >10 kg body weight, initial fluid boluses of 20 mL/kg may be needed if signs of dehydration or shock are present 1
• Maintenance fluids should be administered once rehydration is complete 1, 2

Critical pitfall to avoid: Never use antimotility drugs like loperamide in children with ileus or suspected ileus, as this can lead to paralytic ileus and severe complications. 1, 4 A case report documented a 2-year-old who developed paralytic ileus after loperamide use for diarrhea, requiring 48 hours of conservative management with parenteral fluids before recovery. 4

When to Consider Surgical Consultation

Obtain surgical evaluation if:

• Mechanical obstruction cannot be ruled out 3, 6
• Signs of peritonitis develop 6
• Ileus persists beyond 48-72 hours despite conservative management 6
• Abdominal compartment syndrome is suspected (severe distention with systemic consequences) 5

The distinction between mechanical and functional ileus is critical, as mechanical obstruction may require surgical intervention within 12 hours, though many cases of small bowel obstruction can now be managed conservatively. 6
