Artificial feeding--solid ground, not a slippery slope.

Abstract

Decisions about artificial feeding arouse more controversy than those involving any other life-sustaining treatment. Because food and water are generally considered basic elements of humane care, representing love and concern for the helpless, it is often thought that they must always be provided. In a landmark decision, the Supreme Judicial Court of Massachusetts ruled that a feeding tube could be removed from a patient in a persistent vegetative state if this was consistent with his previously expressed wishes. The case of Paul E. Brophy, Sr., is part of an emerging medical and legal consensus on the withholding of artificial feeding from adult patients. The view is growing that tube and intravenous feeding should be likened to other medical interventions and not to the routine provision of nursing care or comfort. Competent patients have the right to refuse such feeding. Feeding can also be stopped incompetent patients who have earlier stated such a wish.

Predicting coma and other low responsive patients outcome using event-related brain potentials: a meta-analysis.

OBJECTIVE: A meta-analysis was performed to estimate the predictive power (odd ratio, OR) for awakening of auditory event-related potential (ERP) components in low responsive patients with stroke or hemorrhage, trauma, anoxic, post-operative, and metabolic encephalopathy etiologies. METHODS: We reviewed MEDLINE and analyzed citations for retrieved articles. Logistic regressions were applied on patient samples (Glasgow Coma Scale <12) across and for separate etiologies. RESULTS: For stroke and hemorrhage the ORs with 95% confidence intervals were: 2.05 [1.12-3.75] (N100), 4.47 [1.92-10.44] (MMN), 10.29 [2.00-52.79] (P300), for trauma: 1.63 [0.70-3.80] (N100), 4.72 [1.35-16.44] (MMN), 12.89 [4.82-34.43] (P300), anoxic: 8.03 [2.83-22.75] (N100), 15.50 [4.27-56.26] (MMN), 5.93 [2.38-14.77] (P300), post-operative: 10.66 [1.98-57.50] (N100), metabolic encephalopathy: 2.12 [0.34-13.13] (N100), 3.60 [0.28-46.36] (MMN), 7.71 [0.75-79.77] (P300), and all etiologies: 2.85 [1.91-4.27] (N100), 6.53 [3.55-12.01] (MMN), and 8.79 [4.88-15.83] (P300). Based on six N100 studies (N=548 patients), five MMN studies (N=470), and six P300 studies (N=313), the N100, MMN, or P300, when present, significantly predicted awakening, P300 and MMN being significantly better predictors than N100. CONCLUSIONS: The MMN and P300 appear to be reliable predictors of awakening. SIGNIFICANCE: The prognostic assessment of low responsive patients with auditory ERP should take into account both MMN and P300.
