Is hypovolemia after traditional preoperative care in patients undergoing colonic surgery underrepresented in conventional hemodynamic monitoring?
Combination of CP with 12 mmHg, head-down position, and infusion of 1,500 ml fluids compensated relative hypovolemia during colonic surgery. With conventional monitoring, intravascular volume status might be underestimated after traditional preoperative care.
Differential changes occur in brush border amino acid transport during a 3-day period of bowel rest. The apparent gut nutritive transporters for Glutamine and arginine are decreased, although the gluconeogenic transporters for alanine, MeAIB, and leucine are maintained. These adaptive changes may help explain the difficulties seen in postoperative and critically ill patients on prolonged bowel rest.
