Death and organ procurement: public beliefs and attitudes.

Although "brain death" and the dead donor rule--i.e., patients must not be killed by organ retrieval--have been clinically and legally accepted in the U.S. as prerequisites to organ removal, there is little data about public attitudes and beliefs concerning these matters. To examine the public attitudes and beliefs about the determination of death and its relationship to organ transplantation, 1351 Ohio residents >18 years were randomly selected and surveyed using random digit dialing (RDD) sample frames. The RDD telephone survey was conducted using computer-assisted telephone interviews. The survey instrument was developed from information provided by 12 focus groups and a pilot study of the questionnaire. Three scenarios based on hypothetical patients were presented: "brain dead," in a coma, or in a persistent vegetative state (PVS). Respondents provided personal assessments of whether the patient in each scenario was dead and their willingness to donate that patient's organs in these circumstances. More than 98 percent of respondents had heard of the term "brain death," but only one-third (33.7%) believed that someone who was "brain dead" was legally dead. The majority of respondents (86.2%) identified the "brain dead" patient in the first scenario as dead, 57.2 percent identified the patient in a coma as dead (Scenario 2), and 34.1 percent identified the patient in a PVS as dead (Scenario 3). Nearly one-third (33.5%) were willing to donate the organs of patients they classified as alive for at least one scenario, in seeming violation of the dead donor rule. Most respondents were not willing to violate the dead donor rule, although a substantial minority was. However, the majority of respondents were unaware, misinformed, or held beliefs there were not congruent with current definitions of "brain death." This study highlights the need for more public dialogue and education about "brain death" and organ donation.

Diagnostic pitfalls in patients with hypoxic brain damage: three case reports.

OBJECTIVE: Our aim was to assess the possible diagnostic pitfalls in three patients with hypoxic brain damage who had partly conflicting clinical, biochemical, and electrophysiological data and were in a persistent vegetative state (PVS) following cardiac arrest (CA). METHODS: Serum concentrations of the destruction proteins, neuron-specific enolase (NSE) and protein S-100B (S-100B), were measured on days 1-3, and 7; somatosensory evoked potentials (SEPs) were recorded within 48 h and on day 7 after CA. RESULTS: Two patients had significantly increased concentrations of NSE and S-100B during the first 3 days after CA, a finding that indicates ongoing neuronal destruction. In contrast, the SEPs of these patients were normal or showed only a diminished amplitude configuration. In the third patient the SEPs demonstrated a bilateral loss of cortical responses repeatedly, but both destruction proteins were only slightly above the upper normal values on all study days. CONCLUSION: Our findings demonstrate that a poor prognosis can only be established if either SEPs, NSE, or S-100B are very abnormal. The conflicting results in our patients indicate that variable values may reflect different patterns of neuropathological damage caused by diffuse hypoxia. We, therefore, favour a multi-modal approach with a combination of clinical, biochemical, and electrophysiological investigations in order to predict neurological outcome after CA reliably.

[Monoamines, monoamine metabolites, neuron specific enolase and myelin basic protein concentrations in cerebrospinal fluid of resuscitated patients].

Changes of monoamines, monoamine metabolites, neuron specific enolase (NSE) and myelin basic protein (MBP) levels in cerebrospinal fluid were measured in 8 patients for up to 7 days after cardiopulmonary resuscitation. The outcomes were assessed by the Glasgow Outcome Scale. One showed good recovery 3 developed a persistent vegetate state (PVS) and 4 became brain dead (BD). The concentration of NSE increased to a peak about 3 days after resuscitation, then gradually decreased. MBP also showed an increase with time up to 7 days. The time course suggests that neuronal and/or axonal damage progresses for several days after hypoxic or anoxic brain insult. NSE and MBP in the BD group were higher than those in the PVS group, thus CSF levels may be prognostic with regard to hypoxic brain injury. Tyrosine, dopamine, 3-methoxytyramine (3-MT), 3-dihydroxy-4-phenylacetic acid (DOPAC), homovanillic acid (HVA), vanillylmanderic acid (VMA), normetanephrine (NMN), metanephrine (MN), 3-methoxy-4-hydroxyphenylglycol (MHPG), vanillic acid (VA), tryptophan and 5-hydroxyindoleacetic acid (5-HIAA) concentrations were analyzed by HPLC with an electrochemical detector. Concentrations changed within 2 or 3 days after resuscitation, so concentrations at that period may indicate neuronal damage. However, there are some cases with abnormal NSE and MBP levels without abnormal monoamine levels, suggesting that differences in concentrations are not the consequence of the amount of affected neurons, but of the sites of regions.

Prevalence and prognosis of traumatic intraventricular hemorrhage in patients with blunt head trauma.

BACKGROUND: Most studies of traumatic intraventricular hemorrhage (tIVH) contain fewer than 25 subjects and are retrospective in design, providing minimal information about the entity and its clinical significance. METHODS: We prospectively enrolled trauma patients from 18 centers in North America in the National Emergency X-Radiography Utilization Study (NEXUS) II if they received an emergent head computed tomography (CT) scan, as determined by the managing physician. Clinical data were collected at the time of enrollment and CT reports were compiled at least 1 month later. We calculated prevalence and demographics of tIVH from the 18 sites, while outcome data were gathered from medical records of patients with tIVH who were seen at any of six sites that participated in the follow-up portion of the study. We considered patients who underwent a neurosurgical intervention or who had a "poor outcome" (Glasgow Outcome Scale score of 1 to 3, death, persistent vegetative state, or severe disability) to have suffered a "combined outcome." RESULTS: Prevalence of tIVH among all trauma patients who received a head CT was 118 in 8,374, or 1.41%. Among tIVH patients, 70% had a "poor outcome" and 76% had a "combined outcome." A poor outcome appeared to be associated with an abnormal presenting Glasgow Coma Scale score and involvement of the third or fourth ventricle, whereas age appeared to be unrelated. Patients with tIVH and no major associated injury on CT tended to do well; only one patient with isolated tIVH had a poor outcome. CONCLUSIONS: Traumatic IVH is rare and is associated with poor outcomes that seem to be the consequence of associated injuries. Isolated tIVH patients who are clinically well appear to have a functional outcome; we were unable to identify a case of isolated tIVH, combined with a normal neurologic examination, resulting in a poor or combined outcome.

Abandon the dead donor rule or change the definition of death?

Research by Siminoff and colleagues reveals that many lay people in Ohio classify legally living persons in irreversible coma or persistent vegetative state (PVS) as dead that additional respondents, although classifying such patients as living, would be willing to procure organs from them. This paper analyzes possible implications of these findings for public policy. A majority would procure organs from those in irreversible coma or in PVS. Two strategies for legitimizing such procurement are suggested. One strategy would be to make exceptions to the dead donor rule permitting procurement from those in PVS or at least those who are in irreversible coma while continuing to classify them as living. Another strategy would be to further amend the definition of death to classify one or both groups as deceased, thus permitting procurement without violation of the dead donor rule. Permitting exceptions to the dead donor rule would require substantial changes in law--such as authorizing procuring surgeons to end the lives of patients by means of organ procurement--and would weaken societal prohibitions on killing. The paper suggests that it would be easier and less controversial to further amend the definition of death to classify those in irreversible coma and PVS as dead. Incorporation of a conscience clause to permit those whose religious or philosophical convictions support whole-brain or cardiac-based death pronouncement would avoid violating their beliefs while causing no more than minimal social problems. The paper questions whether those who would support an exception to the dead donor rule in these cases and those who would support a further amendment to the definition of death could reach agreement to adopt a public policy permitting organ procurement of those in irreversible coma or PVS when proper consent is obtained.

Residual cerebral activity and behavioural fragments can remain in the persistently vegetative brain.

This report identifies evidence of partially functional cerebral regions in catastrophically injured brains. To study five patients in a persistent vegetative state (PVS) with different behavioural features, we employed [(18)F]fluorodeoxyglucose-positron emission tomography (FDG-PET), MRI and magnetoencephalographic (MEG) responses to sensory stimulation. Each patient's brain expressed a unique metabolic pattern. In three of the five patients, co-registered PET/MRI correlate islands of relatively preserved brain metabolism with isolated fragments of behaviour. Two patients had suffered anoxic injuries and demonstrated marked decreases in overall cerebral metabolism to 30-40% of normal. Two other patients with non-anoxic, multifocal brain injuries demonstrated several isolated brain regions with relatively higher metabolic rates, that ranged up to 50-80% of normal. Nevertheless, their global metabolic rates remained <50% of normal. MEG recordings from three PVS patients provide clear evidence for the absence, abnormality or reduction of evoked responses. Despite major abnormalities, however, these data also provide evidence for localized residual activity at the cortical level. Each patient partially preserved restricted sensory representations, as evidenced by slow evoked magnetic fields and gamma band activity. In two patients, these activations correlate with isolated behavioural patterns and metabolic activity. Remaining active regions identified in the three PVS patients with behavioural fragments appear to consist of segregated corticothalamic networks that retain connectivity and partial functional integrity. A single patient who suffered severe injury to the tegmental mesencephalon and paramedian thalamus showed widely preserved cortical metabolism, and a global average metabolic rate of 65% of normal. The relatively high preservation of cortical metabolism in this patient defines the first functional correlate of clinical- pathological reports associating permanent unconsciousness with structural damage to these regions. The specific patterns of preserved metabolic activity identified in these patients do not appear to represent random survivals of a few neuronal islands; rather they reflect novel evidence of the modular nature of individual functional networks that underlie conscious brain function. The variations in cerebral metabolism in chronic PVS patients indicate that some cerebral regions can retain partial function in catastrophically injured brains.

Coordinated expression in chronically unconscious persons.

The clinically described 'persistent vegetative state' (PVS), consists of wakefulness unaccompanied by any evidence of the subject's awareness of self or environment. Past studies from our own and other laboratories have used positron emission tomography (PET) to study brain metabolism in approximately 20 such patients during wakeful periods. All those efforts identified global cerebral glucose metabolism at or below levels encountered during deep barbiturate anaesthesia. Nevertheless, the clinical literature includes rare reports of relatively isolated cognitive functions expressed by PVS patients late in their course. The observation raises the question of whether such activity reflects awareness or unconscious automatic behaviour. We employed magnetometry (MEG), PET scanning, MR imaging and 24-hour EEG recordings to evaluate three patients clinically vegetative between six months and 20 years after onset. Neither meticulous clinical examinations nor 24-hour EEG and video monitoring provided any hint of cognitive interaction in any subject. Nevertheless, patient 1 uttered single words once every 48 hours or more; patient 2 frequently expressed coordinated, non-purposeful, non-dystonic movements in arms and/or legs; and, patient 3 expressed strong emotional negativity without motor responses to noxious stimuli with occasional quieting in response to prosodic stimuli. All patients had whole-brain averaged global metabolism levels below 50% of normal. Patient 1, however, demonstrated preserved islands of increased metabolism in the posterior frontal and posterior temporal lobes, as well as MEG activations of Heschl's gyrus all located in the left hemisphere. In patient 2, selected increased metabolism was confined to the frontal poles and related subcortical structures. MRI in patient 3 demonstrated severe, bilateral post-traumatic cerebral atrophy. PET metabolism was diffusely reduced to 40% of normal but MEG evoked potentials indicated early and late sensory processing with abnormal later evoked components. The correlation of fragmentary behaviour with preserved metabolic and physiologic activity in cortical and subcortical regions known to support specific modular functions is novel. The finding demonstrates the capacity of severely damaged brains to partially express surviving modular functions without evidence of integrative processes that would be necessary to produce consciousness. We conclude that the mere expression of isolated neuropsychologic activity by isolated modules is insufficient to generate consciousness in overwhelmingly damaged brains.

Acquired mutism: physiopathy and assessment.

The speechless patient presents a unique challenge to the clinician working with neurologically impaired adults. Acquired speechlessness, or mutism, has been associated with a variety of clinical states and syndromes after damage to central and peripheral nervous system structures. The intent of this paper is to summarize the reported states and syndromes associated with acquired mutism (eg, persistent vegetative state, akinesia), and to organize this information in a framework for clinical assessment of the speechless patient. For the purpose of discussion, speech production is divided into five interrelated processes: arousal; cognitive processing; affect and drive; motor initiation, planning, programming, and coordination; and execution of movement. Disorders characterized by mutism are classified according to the process or processes of speech production that primarily are affected. Each subtype of acquired mutism is characterized by a cluster of neurologic signs, which has been incorporated into a decision-making framework for use in a clinical setting.

Chronic vegetative state after severe head injury: clinical study; electrophysiological investigations and CT scan in 15 cases.

Fifteen cases of chronic vegetative state (CVS), following severe head injury and lasting for two years or more, are reported. Vegetative state, in most instances after a period of coma, consists of a return of wakefulness accompanied by an apparent total lack of higher mental activity. A protracted period of vegetative state has been chosen to ensure that the possibility of further recovery could virtually be excluded. The term of CVS could therefore be reasonably used to designate these cases. Moreover, cerebral lesions were then thought to be the same as in neuropathological studies. Severe head injury, responsible for CVS, initially affected adults in 11 cases and children in four cases. The range of duration of the vegetative state was 2 to 14 years, with a mean of five years. The data of clinical study and electrophysiological investigations (EEG, brain stem auditory evoked potentials, somatosensory evoked potentials) are reported. A CT scan was carried out in each case to study the impairment of cerebral hemispheres and brain stem, with particular attention to the ventricular size. The results confirm that in the CVS, lesions affect mainly the hemispheres, while brain stem functions are mainly preserved. Vegetative State (VS) is the term proposed by Jennett and Plum (1972) to describe the condition that sometimes emerges after a period of coma, after a severe head injury (SHI). This condition consists of a return of wakefulness accompanied by an apparent total lack of higher mental activity. A practical definition of this state characterised by wakefulness without responsiveness is that the eyes open spontaneously and/or in response to verbal stimuli. Sleep-wake cycles exist. The patients can neither obey simple orders nor locate painful stimuli. They utter no comprehensible words. Blood pressure and breathing remain steady. It is much more difficult to specify exactly how long such a state must persist before it can be confidently declared permanent. Persistent vegetative state, or chronic vegetative state (CVS) is one of the five categories of the Glasgow Outcome Scale (Jennett and Bond, 1975). Bricolo et al (1980) think that the term CVS should never be applied before completion of the first year after the onset of traumatic coma. It actually seems possible to exclude the possibility of any further recovery after unresponsiveness for one year. The term CVS may then be rightfully used to denote this condition. For such protracted periods of VS, we have tried to state in a retrospective study the clinical and electroencephalographic (EEG) course.(ABSTRACT TRUNCATED AT 400 WORDS)

Legal and ethical aspects of the vegetative state.

The diagnosis of persistent or permanent vegetative state (PVS) raises ethical and legal problems. Strict adherence to the doctrine of the sanctity of life would require carers to continue to maintain the individual, perhaps for many years. However, few would regard this as an appropriate outcome when the person clearly has no capacity to interact with the environment and has no likelihood of recovery. However, the ethical and legal commitment to the sanctity of life has led courts to employ a variety of approaches to this situation in order to find a way in which the person in PVS can be allowed to die. It is argued that each of the approaches is disingenuous and ultimately unhelpful. What the law is doing is endorsing non-voluntary euthanasia, but dressing it up as something else. This is unhelpful for all concerned and the time has come for a review of all end of life decisions so that doctors, patients, and relatives can make honest decisions without fear of legal reprisal.

Predicting the health-related values and preferences of geriatric patients.

BACKGROUND: Those who must make health care decisions on behalf of persons who lack decision-making capacity often have too little information. The purpose of this study was to determine whether and to what degree sociodemographic factors, social support, religious involvement, and functional status served as predictors of the health-related values and preferences of geriatric patients. METHODS: A retrospective chart review involving 178 cognitively intact patients enrolled at a geriatric clinic at a university medical center was conducted. Patient variables included age, race, sex, marital status, years of education, participation in formal religious activities, self-reported functional status, and adequacy of social and family support. These were compared with responses to a modified version of the Values History questionnaire, an established method of evaluating patient values that includes advance directives. RESULTS: Patients were likely to value quality (82%) over quantity of life (18%) and the ability to think clearly (64%) over 13 other specific health-related values. They were likely (93%) to want to be taken to a hospital emergency department on losing consciousness or becoming confused. Seventy-eight percent expressed a desire to be resuscitated using cardiopulmonary resuscitation (CPR), and 76% expressed a preference for use of a respirator, if necessary. Most (85%) considered a permanent vegetative state to be worse than death. High functional status predicted a preference for quality of life over length of life and the perception of a persistent vegetative state as worse than death (positive predictive value = 89%). Persons with better social and family support were more likely to accept treatment with CPR or a respirator and less likely to consider a permanent vegetative state to be worse than death. No single patient factor was strong enough to increase the probability of a particular value or preference by more than 17% above baseline. CONCLUSIONS: Sociodemographic and functional status variables are relatively weak predictors of personal values and directives. This reinforces the importance of routinely eliciting patient values and preferences and of updating the information, particularly following changes in functional status or family support. Baseline information regarding the health-related values and preferences of this primary care geriatric clinic population may provide valuable information about the values and preferences of decisionally impaired older patients.

Reduced mortality after severe head injury will increase the demands for rehabilitation services.

PRIMARY OBJECTIVE: In 1989, a new therapy to reduce intracranial pressure in severely head-injured patients was introduced in Lund. The new treatment reduced mortality significantly. The present study describes the quality of life for the survivors. METHODS AND PROCEDURES: The study includes 53 patients treated during 1989-1994, according to a new treatment protocol for increased intracranial pressure ('Lund concept' group). During 1982-1986, 38 patients were managed according to a protocol including high dose thiopentone ('Thiopentone' group). The two groups are compared regarding neurophysical and psychiatric symptoms as well as aspects regarding the patient's role, performance, interpersonal relationship, frictions, feelings and satisfaction in work, areas of social and leisure activities, and extended family. RESULTS: Mortality was reduced from 47% to 8%, but the number of patients with a persistent vegetative state and/or remaining severe disability did not increase. However, the number of patients with persisting emotional and intellectual deficits increased significantly. CONCLUSION: The new treatment regime has dramatically increased the number of survivors after severe head trauma. Although most patients have a favourable outcome, there are more patients with remaining sequelae and disabilities, and the demand for qualified rehabilitation has increased.

Spontaneous blinking behaviour in persistent vegetative and minimally conscious states: relationships with evolution and outcome.

There is evidence that spontaneous blinking correlates with cognitive functions. This arises from the observation that blinking rate (BR) is modulated by arousal levels, basic cognitive processes (e.g., attention, information processing, memory, etc.) and more complex cognitive functions (e.g., reading, speaking, etc.). The aim of this work was to test the role of BR evaluation in the assessment of cognitive network functioning in awake patients with consciousness deficits. Thirteen patients were recruited for the study, and were assessed by the Glasgow coma scale (GCS) and Glasgow outcome scale (GOS) on admittance and discharge, respectively. A level of cognitive functioning scale (LCFS) score was assigned at every change in awareness or at least every 2 weeks. At the same time as the clinical tests, the BR was observed for a 5-min period. Ten healthy subjects, observed throughout three non-consecutive days, formed the control group. The BR underwent a different temporal behaviour in the two diagnostic categories. In the persistent vegetative state (PVS) group it remained stable throughout time and linked with the clinical conditions of the patients; whereas in the non-persistent vegetative state (NPVS) group it decreased over time as the cognitive conditions improved. Moreover, a strong inverse correlation was found between overall BR values and LCFS scores. We have concluded that the blinking behaviour changes manifested in PVS and NPVS patients reflect different evolution phases of a cholinergic-dopaminergic imbalance, and that a reduced BR characterizes the early stages of consciousness recovery.

Response after out-of-hospital cardiac arrest in the trauma patient should determine aeromedical transport to a trauma center.

OBJECTIVE: To evaluate whether aeromedical transport of trauma patients who sustain an out-of-hospital cardiac arrest (OHCA) is justified. DESIGN: Retrospective chart review. METHODS: We reviewed the outcome of 67 consecutive patients after OHCA with initial resuscitation who were transported to a Level I trauma center. Statistical analysis was used to develop a predictive model for survival. RESULTS: The overall survival was 19%. One of 28 patients with a second OHCA survived (p = 0.005). Logistic regression analysis demonstrated that the Revised Trauma Score at trauma center arrival (1.0 +/- 0.25, nonsurvivors vs. 5.15 +/- 0.86, survivors, p = 0.0001), Injury Severity Score (34.9 +/- 2.9, nonsurvivors vs. 21.3 +/- 4.1, p = 0.037) and a sinus-based cardiac rhythm at the time of aeromedical team arrival were predictive of survival (R2 = 0.57, p = 0.0001). Survivors were more likely to have been transported from an outside hospital (28% vs. 8% for scene runs), had a sinus rhythm on team arrival (42% vs. 3%), and maintained a sinus rhythm on arrival at the trauma center (41% vs. 0%); however, these parameters were not predictive of survival in the statistical model. The neurologic outcome of the 13 survivors was good (preinjury state) in three cases, moderate disability (independent living) in three, severe disability (needing assistance) in five, and persistent vegetative state in two. Regression analysis was unable to differentiate survivors with a good neurologic recovery from the rest of the patient population. CONCLUSIONS: These results suggest that: (1) trauma patients who are resuscitated to a sinus rhythm after OHCA should be transported to a trauma center; (2) Revised Trauma Score and Injury Severity Score are useful to predict survival; and (3) neurologic outcome is not accurately predicted by this model.

Evaluating the comatose patient. Rapid neurologic assessment is key to appropriate management.

Coma is defined as a sleeplike state in which the patient is unresponsive to self and the environment. Coma should be distinguished from the persistent vegetative state and locked-in syndrome. It is important to obtain a carefully taken history from eyewitnesses and to perform a rapid neurologic examination focusing on pupillary responses, eye movements, and motor responses. Pupils reactive to light usually indicate metabolic or medical coma; cerebellar infarction or hemorrhage is a notable exception. A pupil unreactive to light often points to a structural brain lesion and the need for urgent neurosurgical consultation. The prognosis for coma depends on the cause.

Termination of nutrition and hydration in a child with vegetative state.

A child in a vegetative state may present difficult decisions for physicians and families regarding the course of treatment. We report a case of a child who entered a prolonged vegetative state following status epilepticus. The child's parents requested termination of artificial means of nutrition and hydration. That request culminated in a complex legal intervention by multiple state agencies and attracted local media attention. This article presents the details of the case and discusses the medical and legal complexities encountered. The diagnosis and prognosis of the persistent vegetative state in children have recently been defined. Decision making in these circumstances should be based on adequate, careful clinical evaluation of the medical facts. Hospital ethics committees can provide an independent forum in which the diverse viewpoints in a case may be examined. Decision making should optimally be accomplished between families and caretakers.

Beyond the Cruzan case: the U.S. Supreme Court and medical practice.

In a landmark decision, the U.S. Supreme Court affirmed a Missouri ruling that sharply limited family decisions about life-sustaining treatment for incompetent patients. The Court held that the Constitution protects the refusal of life-sustaining treatment by competent patients. For incompetent patients, states may require "clear and convincing" evidence of refusal, specifically for the withdrawal of tube feedings, if such a person were in a persistent vegetative state. The ruling left many clinical questions unanswered, such as whether life-sustaining treatment must be given to terminally ill incompetent patients, whether patients may refuse artificial feedings, and what constitutes clear and convincing evidence of refusal. The decision also has potentially harmful consequences. It may undermine family decision making, encourage cynicism and disregard of the law, and promote defensive medicine. Physicians can minimize such consequences by encouraging patients to provide advance directives, such as the durable power of attorney for health care, by urging legislative action, and by setting national practice standards for decisions regarding incompetent patients.

Coverage of coma in headlines of US newspapers from 2001 through 2005.

OBJECTIVE: To review journalists' preferences and accuracy in reporting comatose states. METHODS: Using the Lexis-Nexis database, we selected newspaper headlines from January 1, 2001, through December 31, 2005, that included the words coma, comatose, unconsciousness, vegetative state, awakening, and brain dead. RESULTS: We identified 340 stories by headlines. The median age of persons in coma was 26 years. Coma cases in men were twice as common as those in women. In 71% of coma cases, the cause of coma was associated with motor vehicle crashes or violence. Persistent vegetative state was reported in 25 articles (7%), frequently when a family or physician conflict emerged. In 33 stories (10%), coma was medically induced but not mentioned in the headline. Three "miracle" recoveries involved resumption of speech in patients in a minimally conscious state. CONCLUSION: Few news reports had gross inaccuracies or misrepresentations; however, definitional difficulties of unconscious states with the reporters remain. The reporting of coma may be biased toward violence and trauma. Medically induced coma was present in 1 of 10 reports but rarely mentioned in the headline.
