Futility-of-care decisions in the treatment of moribund intensive care patients in a developing country.

PURPOSE: To analyze the characteristics of moribund patients in a surgical intensive care unit (ICU) and highlight the dilemmas inherent in treating such patients. METHODS: Data on all patients admitted to the surgical ICU during the period of three years from July 1999 to June 2002 were collected prospectively. Data were collected on very ill patients who died, in whom it appeared obvious that treatment could not have improved their condition and whose death could have been anticipated. The case notes were subjected to further analysis to determine the difficulties encountered in managing patients whose therapy was considered to be futile. RESULTS: Of 662 admissions, 100 (15.1%) died and 30 (4.5%) patients were treated aggressively, even after a prognosis which reflected futile treatment. The overall mean length of stay for survivors was 7.5 +/- 9.0 [standard deviation (SD)] days and that for the non-survivors was 12.8 +/- 18.1 (SD; P < 0.001). The cost incurred for the treatment of non-survivors was significantly higher than that for the surviving patients. The factors relating to the decisions to continue futile therapy were age of the patient, legal considerations, family wishes and differing opinions between treating physicians. CONCLUSION: Consideration of futility during end-of-life care did not receive adequate attention in this unit which incurred additional human and material resources.

[Prognosis of the apallic syndrome. A literature review].

This study evaluates the available literature about the prognosis of patients with apallic syndrome and similar illnesses. Different therapeutic strategies are not relevant in this review. The variation of the reported material did not permit a statistical metaanalysis. However, many interesting points of view could be elaborated leading to positive assistance in everyday situations. The chance of survival and the long-term outcome of comatose patients decrease with an increase in the age of the patient, the length and the degree of the coma. Cerebral predamage worses the long-term prognosis. Traumatic head injuries have a better prognosis than nontraumatic. Children (under 18 years of age) have a better prognosis than adults. The course of the oculomotoric symptoms can be used as a prognostic criterion. The somatosensory evoked potentials in the early phase correlate with the survival-chance and the long-term prognosis. The initial speed of recovery correlates with the long term outcome. Children and adults with traumatic apallic syndrome may recover over a period of 12 months. For apallic patients with other etiologies this time limit is 3 months. Few cases of recovery have been described outside these time limits. The average survival limit of permanent apallic patients is between 3 and 5 years. Particular patients have survived decades.

Prognostic implications of hyperglycaemia in paediatric head injury.

Fifty children with head injury were evaluated in an attempt to establish a correlation between post-traumatic hyperglycaemia and long-term outcome. In all the patients, the blood glucose level was measured on admission and on the days following the trauma (threshold of normal value set at 150 mg/dl). Hyperglycaemia was seen more frequently in children with severe head injury than in those with mild and moderate head injury. It was present in 87.5% of the patients with a Glasgow Coma Score (GCS) < or =8 (the average blood glucose level on admission was 237.8+/-92 mg/dl), in 60% of the patients with a GCS of 9-12 (178+/-78.7 mg/dl) and only in 25% of those with a GCS of 13-15 (131.5+/-39 mg/dl). A close correlation was also seen between the outcome and the blood glucose level. In fact, the blood glucose on admission was higher in the patients with a poor outcome, i.e. in those having a Glasgow Outcome Score (GOS) of 2 or 3 and in those who died (GOS 1), than in the patients with a good outcome (GOS of 4 or 5). Finally, hyperglycaemia persisted beyond the first 24 h after trauma in all the children who died or who survived with a poor outcome. Hyperglycaemia, and especially its persistence over time, appears to be an important negative prognostic factor in children with head injury.

Transient tetraplegia and vegetative dysfunction depending on cervical positioning caused by a cervical spinal chordoma.

A 39-year-old man with acquired torticollis suffering from cervicobrachialgia and neurological deficits is presented. Due to a change in head position a transient reproducible tetraplegia and severe vegetative dysfunctions were caused. The origin of this uncommon serious combination of symptoms and signs was a chordoma of the upper cervical spine. After surgical decompression the patient was free of neurological deficit and pain. Review of the literature did not reveal any similar case.

Characteristics and analysis of risk factors for mortality in infective endocarditis.

OBJECTIVE: The aim of our study was to establish the etiology of and risk factors for infective endocarditis (IE) and determine the prognostic factors for adverse outcome during hospital admission in a Turkish population. MATERIAL AND METHODS: Between January 2002 and January 2004, the clinical and laboratory features of 112 consecutive adult patients (>18 years) with diagnosis of IE who were referred to the infectious diseases clinics/departments of 17 teaching hospitals in Turkey were evaluated. Cases of IE were defined according to the modified Duke Criteria. Mortality was defined as death occurring within 30 days or during hospital stay period. Univariate and multivariate analyses were performed to predict the factors related to fatal outcome. RESULTS: A total of 112 consecutive patients presented with 101 definite and 11 probable IE episodes were defined according to the modified Duke Criteria. The mean age was 45.2+/-19.9. Fifty percent of the patients were male. Ninety (60.4%) of the 112 patients had risk factors for IE and 48 (42.9%) of them had >or=2 risk factors. On the other hand, 49.1% of patients had cardiac risk factors. Blood cultures were positive in 94 (83.9%) cases. Staphylococci were the most common agents (50.0%), followed by streptococci (28.7%) and enterococci (16.0%). Native cardiac valves were detected in 93 (83%) of the episodes of suspected IE. Valvular involvement was present in 103 (92%) patients; the mitral valve, alone or in combination with other valves, was affected in 70 (62.5%) of the patients. Echocardiography detected vegetations in 105 patients (93.8%). The mortality rate was 28.6%. Three factors were independently associated with mortality: haemodialysis OR: 14.5 (95% CI: 1.5-138.2), mobile vegetation OR: 4.8 (95% CI: 1.5-15.4) and mental alteration OR: 4.1 (95% CI: 1.1-15.6). CONCLUSION: Mortality is still high in IE. Our data indicate that patients with altered mental status, mobile vegetation, or on haemodialysis had poorer prognosis.

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.

Magnetic resonance images in hanging.

Hanging is a devastating method of suicide and unfortunately is common in Japan. Although several CT findings of the head have been reported, there have not been any reports about magnetic resonance imaging (MRI) in hanging. We report here interesting MRI findings in a patient after hanging. A 39-year-old woman was transferred to our department after attempting suicide by hanging. Respiration had probably ceased for about three minutes but heart had not stopped when she was pulled down by her father. After her father performed cardiopulmonary resuscitation, she started to breathe immediately. She was treated conservatively in our intensive care unit for 14 days, her condition became stable. Ten days after admission, MRI demonstrated symmetrical hyperintensity on T1-weighted images and relative hyperintensity on T2 weighted images in bilateral lentiform nuclei and medial thalami. There have been several reports about characteristic MRI findings in the case of acute global cerebral ischaemia caused by severe hypoglycaemia or longstanding cardiopulmonary arrest. It was postulated that these specific findings reflected tissue degeneration, deposition of mineral substances, or lipid accumulation. These MRI findings suggest that severe acute global cerebral hypoperfusion also occurs in hanging in the same way as in long-standing cardiopulmonary arrest and that hanging has devastating sequelae.

Position of the American Dietetic Association: ethical and legal issues in nutrition, hydration, and feeding.

It is the position of the American Dietetic Association that the development of clinical and ethical criteria for the nutrition and hydration of persons through the life span should be established by members of the health care team. Registered dietitians should work collaboratively to make nutrition, hydration, and feeding recommendations in individual cases. Registered dietitians have an active role in determining the nutrition and hydration requirements for individuals throughout the life span. When patients choose to forgo artificial nutrition and hydration, or when patients lack decision-making capacity, and others must decide whether or not to provide artificial nutrition and hydration, the registered dietitian has an active and responsible professional role in the ethical deliberation around that decision. There is strong clinical, ethical, and legal support both for and against the administration of food and water when issues arise regarding what is or is not wanted by the patient and what is or is not warranted by empirical clinical evidence. When a conflict arises, the decision to administer or withhold nutrition and hydration requires ethical deliberation. The registered dietitian's understanding of nutrition and hydration within the context of nutritional requirements and cultural, social, psychological, and spiritual needs provides an essential basis for ethical deliberation on issues of nutrition and hydration.
