The patient with diagnosed occlusion of the superior mesenteric artery is stabilised before laparotomy by:

  • treating any underlying condition, e.g. atrial fibrillation - caution should be taken since digitalization causes splanchnic vasoconstriction
  • correcting shock with IV fluid, especially blood and plasma - central venous pressure and urine output are monitored
  • bicarbonate may be needed to correct acidosis
  • antiobiotic therapy should be commenced pre-operatively, e.g. cefuroxime 750mg / 6 hourly
  • intra-arterial infusion of papaverine via the angiogram catheter may relieve some of the associated arterial spasm
  • analgesia
