Document Summary

Islets of langehans (endocrine) duct: conglomerate of endocrine cells, secrete hormones into blood vessels, alpha cells = secretes glucagon. In highly vascularized areas of the pancreas: glucagon to help maintain normal blood glucose levels, beta cells = secretes insulin and amylin. Insulin brings glucose into the cells: amylin, enhances the action of insulin, helps control gastric emptying which also contributes to glucose levels, delta cells = secretes somatostatin, somatostatin. Increased c-reactive protein (crp: elevated plasma glucose ( > 200 mg/dl, elevated wbc count. Initial feeding of low fat, soft diet (more of what pt will accept: low fat diet may be better tolerated because of lack of lipase. Ischemic bowel: prolonged si ileus (no peristalsis, nonfunction gi, high output fistula/obstruction. Insufficient absorptive capacity: do not start pn before day 5, avoid overfeeding, monitor, tg, blood glucose, protein = 1. 2-1. 5 g/kg, kcal = 25-35 kcals/kg.
