Cumulative evidence of potential benefits of electroencephalography (EEG) and evoked potentials in the management of patients with acute cerebral damage has been confirmed. Continuous EEG monitoring is the best method for detecting nonconvulsive seizures and is strongly recommended for the treatment of status epilepticus. Continuously displayed, validated quantitative EEG may facilitate early detection of secondary cerebral insults and may play a decision-making role in the management of patients with head injury, stroke, or subarachnoid hemorrhage. ⋯ Motor evoked potentials may become clinically important both in acutely injured and elective postoperative patients. In the neurointensive care units adequate techniques can be selected to answer targeted clinical questions. The efficacy can be improved by implementing educational projects based on ad hoc training of nurses and neurointensive care specialists.

With increasing interest in enteral feeding and the role of the gut in the development of infection and multiple organ failure in critically ill patients, the use of enteral feedings enriched with immune-enhancing ingredients is attracting considerable interest. This approach to modulating the immune and inflammatory responses has become known as immunonutrition, and many products are now available for clinical use. ⋯ Two systematic reviews have been published, both with positive results. Nevertheless, as new products become available they should be subjected to controlled clinical trials, especially because several of the mechanisms involved are not yet fully understood.

ReviewDiagnosis of intra-abdominal infection in the critically ill patient.
Intra-abdominal infection continues to pose a significant threat to critically ill patients in the year 2000. A review of the current literature reveals that despite remarkable developments in critical care medicine and extensive study of patients with tertiary peritonitis, the associated mortality rate remains nearly 30%. ⋯ Scoring systems developed to identify those patients at risk for progression to tertiary peritonitis, the more chronic, lethal form of intra-abdominal infection associated with multisystem organ failure, reflect the current emphasis in the literature on the importance of early diagnosis and early intervention. This has led to a renewed interest in conservative, data-dependent surgical management employing radiographic and microbiologic evidence to guide therapy.

Small bowel transplantation has become the treatment of choice for patients with chronic gut failure whose illness cannot be maintained on home parenteral nutrition. Outcomes have improved as a result of refinements in patient selection, surgical techniques, and the prevention, diagnosis, and treatment of graft rejection. Early listing is important because of the shortage of organ donors. ⋯ Sepsis rates are also higher for patients who have had small bowel transplantation than for those who have received other organs because of bacterial translocation from the gut secondary to preservation injury and graft rejection. Graft and patient survival rates after small bowel transplantation are comparable to rates after lung transplantation. Successful transplant recipients resume unrestricted oral diets.
