Initial Treatment for Paralytic Ileus

Immediate Management Steps

The American Gastroenterological Association recommends maintaining nil per os (NPO) status until bowel function returns, as oral intake is not suitable during paralytic ileus due to impaired gastric emptying and intestinal transit 1, 2
The World Journal of Emergency Surgery suggests placing a nasogastric tube for decompression to relieve abdominal distension and prevent aspiration 3
The American Gastroenterological Association recommends providing adequate intravenous fluid resuscitation to correct fluid and electrolyte imbalances 1, 3
The World Journal of Emergency Surgery advises discontinuing or minimizing medications that can worsen ileus, particularly opioids 1, 2

The European Society of Gastrointestinal Motility recommends avoiding antidiarrheal medications such as loperamide and diphenoxylate, which can worsen ileus 4, 5
The American Gastroenterological Association suggests considering prokinetic agents such as metoclopramide for stimulating gastrointestinal motility 6, 3
The European Society of Gastrointestinal Motility recommends considering neostigmine for persistent cases of paralytic ileus 3
The American Gastroenterological Association advises using antibiotics such as rifaximin, metronidazole, or amoxicillin-clavulanic acid if bacterial overgrowth is suspected in prolonged ileus 4, 7, 8

The American Gastroenterological Association recommends considering enteral nutrition via feeding tube or parenteral nutrition if oral intake is inadequate for more than 7 days 9, 3
The European Society of Gastrointestinal Motility suggests starting with clear liquids and progressing to small, frequent meals with low-fat, low-fiber content when reintroducing oral feeding 9, 5
The American Gastroenterological Association recommends preferring enteral nutrition over parenteral nutrition when the gut is accessible and functioning 9

The World Journal of Emergency Surgery recommends encouraging early mobilization as soon as the patient's condition allows to stimulate bowel motility 1, 3
The American Gastroenterological Association advises optimizing fluid management by avoiding overhydration, aiming for weight gain <3 kg 3
The World Journal of Emergency Surgery suggests considering thoracic epidural analgesia for pain management in postoperative ileus 1, 2

The American Gastroenterological Association recommends assessing for return of bowel sounds, passage of flatus, and bowel movements 3
The American Gastroenterological Association advises reassessing the effectiveness of therapy daily and adjusting management accordingly 3

The World Journal of Emergency Surgery warns against continuing opioid medications, which exacerbate ileus 1, 2
The American Gastroenterological Association advises against premature initiation of oral intake before return of bowel function 3

The American Society for Parenteral and Enteral Nutrition recommends increasing the volume or changing the type of food, but not both at the same time, to assess tolerance 10, 11, 12
The European Society for Clinical Nutrition and Metabolism suggests that if the volume is increased, the osmolarity of the food should remain the same 10, 11, 12
Tolerance is assessed based on the presence or absence of nausea, vomiting, abdominal distension, or diarrhea 10, 11

The American Gastroenterological Association recommends considering continuous enteral nutrition through a tube for 4-24 hours using a volumetric pump if oral tolerance is poor 10, 11, 13, 12
The advantage of continuous administration is to maximize the functional capacity of the gastrointestinal tract 10, 11

The World Health Organization recommends breast milk as the first choice for infants with impaired gut function 11, 13
If breast milk is not available, start with elemental formula, then switch to extensively hydrolyzed formula, and finally to polymeric formula 11, 13

The European Society for Clinical Nutrition and Metabolism suggests increasing the volume of food slowly according to digestive tolerance in severe intestinal failure 10, 11, 13, 12
Tolerance is usually assessed from diarrhea or stoma output 10, 11, 12

The American Society for Parenteral and Enteral Nutrition recommends considering enteral nutrition through a tube or parenteral nutrition if oral intake is not adequate for more than 7 days 10, 11, 12
Provide minimal enteral nutrition whenever possible to maintain gut mucosal structure, promote adaptation, and reduce the risk of parenteral nutrition-associated liver disease 10, 11, 12

Do not make several changes at once, as it will be difficult to assess tolerance 10, 11, 13, 12
