Overview

Mesenteric ischemia is a medical emergency and requires prompt treatment. The mainstay of treatment is surgery if bowel necrosis or gangrene has occurred , whereas medical therapy is considered initially for hemodynamically stable patients.

Medical Therapy

The treatment of choice, medical versus surgical in mesenteric ischemia depends on three key elements:

  • Duration and severity of ischemia of the intestine
  • Nature of the occlusive lesion
  • Availability of the immediate surgical or interventional radiology facility in the emergency room
  • Hemodyanamic stability of the patient

Pharmacological therapy

Pharmacologic medical therapies for mesenteric ischemia in patients who are hemodynamically stable and no evidence of bowel ischemia include the following

Initial management:

Mesenteric ischemia is an acute emergency condition that requires prompt intervention. The outline of initial medical management of all types of meseneteric ischemia includes:[1][2][3]

  • Supplemental oxygen
  • Pain control
  • Fluid resuscitation
  • Hemodynamic support and monitoring
  • Correction of electrolyte abnormalities
  • Anticoagulation with heparin, to limit thrombus propagation
  • Broad sprectrum antibiotics
  • Gastrointestinal decompression
  • Avoidance of vasopressors, which can exacerbate ischemia
  • Proton pump inhibitors
  • Measurement of electrolytes and acid base status

Pain control:

Parenteral opoids are used to control the pain.

Fluid resuscitation:

Patients suspected of having mesentric ischemia should be resuscitated with crystalloids and blood products to prevent cardiovascular collapse.

Hemodynamic support and monitoring:

In order to guide effective resuscitation, effective hemodyanamic support and monitoring should be implemented.

Anticoagulation with heparin:

Broad sprectrum antibiotics:

Avoidance of vasopressors:

Measurement of electrolytes and acid base status:

Management according to the severity of presentation:

Acute embolic mesenteric ischemia is managed according to the hemodyanamic stabilty or the presence/abscene of peritoneal signs.
