From the Guidelines
The initial management for mesenteric edema with small bowel obstruction should begin with supportive treatment, including intravenous crystalloids, anti-emetics, and bowel rest, as soon as possible. This approach is crucial in preventing further complications and allowing for the potential resolution of the edema and obstruction.
Key Components of Initial Management
- Intravenous crystalloids, such as isotonic dextrose-saline crystalloid and balanced isotonic crystalloid replacement fluids containing supplemental potassium, should be administered in an equivalent volume to the patient’s losses 1.
- Nasogastric suction can be both diagnostically useful to analyze gastric contents and therapeutically important to prevent aspiration pneumonia by decompressing the proximal bowel 1.
- A Foley catheter should be inserted to monitor urine output, ensuring that the patient's fluid status and renal function are closely observed 1.
Additional Considerations
- The patient should be kept nil per os (NPO) to reduce intestinal workload and minimize the risk of further complicating the obstruction.
- Pain management and broad-spectrum antibiotics may be considered based on the patient's clinical presentation and the presence of signs of infection or perforation.
- Serial physical examinations, laboratory tests, and abdominal imaging with CT scans are essential for monitoring the patient's condition and assessing the need for potential surgical intervention.
From the FDA Drug Label
Edema The usual initial dose of furosemide is 20 to 40 mg given as a single dose, injected intramuscularly or intravenously The intravenous dose should be given slowly (1 to 2 minutes). Therapy should be individualized according to patient response to gain maximal therapeutic response and to determine the minimal dose needed to maintain that response.

The therapy should be individualized according to patient response to achieve the maximal therapeutic effect while determining the minimal dose required to maintain this response 2.
From the Research
Initial Management for Mesenteric Edema with Small Bowel Obstruction
The initial management for mesenteric edema with small bowel obstruction involves several key steps:
- Medical resuscitation, including intravenous hydration and correcting electrolyte abnormalities 3
- Administration of intravenous antibiotics 3
- Nil per os (nothing by mouth) 3, 4
- Nasoenteral suction 3
Diagnostic Approach
Abdominal CT with oral and intravenous gastrografin contrast is highly sensitive and specific in detecting and characterizing small bowel obstruction 3
- CT findings such as free intraperitoneal fluid, mesenteric edema, and small bowel wall thickening can indicate the need for operative intervention 5
Predictive Factors for Operative Intervention
Several factors can predict the need for operative intervention, including:
- Free intraperitoneal fluid 5
- Mesenteric edema 5
- Lack of the "small bowel feces sign" 5
- History of vomiting 5
- Presence of peritonitis, pneumatosis intestinalis, or pneumoperitoneum 6
Conservative vs. Operative Treatment
The treatment of adhesions small bowel obstruction should be conservative at the beginning, except in cases with clinical and/or CT-scan findings predictive of surgical treatment 6
- A combination of specific oral medications, including an oral laxative, a digestant, and a defoaming agent, can decrease the need for operative intervention in patients with adhesive, partial small-bowel obstruction 4
