Complications of colonic diverticula that may require surgical con- sultation or intervention are hemorrhage and the complications of perforation of a diverticulum purchase nootropil medications gout, which include chronic left lower quad- rant pain order genuine nootropil medicine grace potter, phlegm buy voveran 50 mg overnight delivery, abscess, peritonitis, ﬁstula, and stricture. The source of the bleeding is generally right sided, even though the diverticula predominantly are present on the left. The majority of patients (70–82%) stop bleeding; up to one third continue to bleed and require intervention. Once resuscitation is under way, attention is directed toward local- ization of the source. If the nasogastric tube and proctosigmoidoscopic evaluation suggest a distal source, a nuclear medicine test is the pre- ferred ﬁrst step. Angiographic localization is attempted in those with a positive nuclear medicine scan. In most cases, the perforation is microscopic, causing localized inﬂam- mation in the colonic wall or paracolic tissues. In more severe cases, an abscess may form or the diverticulum freely may rupture into the peri- toneal cavity, causing generalized peritonitis. The average age at pre- sentation is the early 60s; more than 90% of cases occur after 50 years of age. Patients with acute diverticulitis typically present with the gradual onset of left lower quadrant pain and low-grade fever. On physical examination, tenderness to pal- pation usually is present in the left lower quadrant or suprapubic region. Rectal examination may reveal a boggy mass anteriorly if a pelvic abscess is present. Unlike diverticulosis, acute diverticulitis usually is not associated with hemorrhage, but 30% to 40% of cases have guaiac-positive stool. Plain-ﬁlm abdominal series including an upright chest x-ray should be obtained to rule out free intraperitoneal air or lower lobe pneumo- nia. These studies may be normal or may demonstrate a distal large- bowel obstruction, localized ileus, or extracolonic air. Note the “streaking” of the fat characteristic of inﬂammation and the thickening of the sigmoid colon bowel wall. Ideal patients for outpatient management are those who are able to tolerate a diet, have no systemic symptoms or peritoneal signs, and are reliable. Immunocompromise, steroid therapy, and advanced age are contraindications to outpatient therapy (see Algo- rithm 25. Purulent or fecal peritonitis may develop secondary to rupture of a contained abscess or free perforation of a diverticulum.

The latter, for instance, may not be appropriate for patients requiring anticoagulation therapy. An extensive listing of currently available enteral and parenteral nutrition formulations is provided in Tables 3. This is intended as a template for the initial prescription and should be modiﬁed according to clinical conditions. Enteral Formulas There are several basic categories of enteral formulas: Standard, isotonic formulas contain an appropriate balance of carbo- hydrate, protein, and fat and usually are tolerated well because of low osmolarity (approximately 300mOsm/L) and caloric density (1. These are considered low-residue diets in that they do not contain ﬁber and are used in stable patients with signiﬁcant hypermetabolism. Standard, ﬁber-containing formulas are similar to the isotonic prod- ucts and usually contain both a higher protein content as well as soluble and insoluble ﬁber. These often are fed to critically ill patients via jejunostomy tubes and appear to reduce the incidence of diarrhea. Osmolarity is higher than standard formulas and the propensity for diarrhea is increased. Elemental/peptide-based formulas contain predigested proteins that may promote absorption in patients with malabsorption. Their higher osmolarity and lower fat content require a slower infusion rate initially. Special formulas for organ dysfunction have been designed speciﬁ- cally for patients with established or evolving organ failure.

Hold feedings for 4 hours if the residual is greater than the hourly rate, and notify physician if two consecutive measurements are excessive.

These formulas may prove useful in managing the complications associated with speciﬁc conditions, although evidence that they prolong life is limited. Complications of Enteral Feeding: The most common complications of enteral feeding include diarrhea, aspiration, vomiting, distention, metabolic abnormalities, and tube dislodgment.
