Obstinación terapéutica y su límite con la ética: ¿cuándo detenerse? / Therapeutic effort limit, when do we stop?

Obstinacy or therapeutic cruelty is a medical practice based on the application of extraordinary and disproportionate methods of life support in terminally ill or irrecoverable patients. It is not without risks and can cause physical, psychological and social damage, which is why this practice is not ethically acceptable. It violates the four principles of bioethics: non-maleficence, beneficence, justice and autonomy. The reasons that lead to therapeutic obstinacy are: 1) lack of a definitive diagnosis; 2) false expectation of improvement of the patient; 3) disagreement (between doctors and family or between doctors themselves) with respect the patient's situation; 4) difficulty in communicating with the patient and his/her family; 5) compliance with unrealistic or futile treatments; 6) cultural or spiritual barriers and 7) medical-legal aspects. Limitation of therapeutic effort (LTE) is a deliberate or thoughtful decision about the non-implementation or withdrawal of therapeutic measures that will not provide significant benefit to the patient. But, refusing a treatment, must not imply the artificial acceleration of the death process. Chile does not contemplate euthanasia or assisted suicide in its legislation. Criteria used to justify the limitation of the therapeutic effort are: 1) futility of the treatment (futility); 2) declared wishes of the patient; 3) quality of life and 4) economic cost. The Healthcare Ethics Committee of the Hospital de Urgencia Asistencia Pública has prepared a LET Clinical Guide, proposing a decision-making flow chart that takes in account the autonomy of the patient, the opinion of the medical team, patient and family. In case of disagreement, the Healthcare Ethics Committee's may be requested to issue a pronouncement.

La obstinación o ensañamiento terapéutico es una práctica médica basada en la aplicación de métodos extraordinarios y desproporcionados de soporte vital en enfermos terminales o irrecuperables. No está exenta de riesgos y puede producir daño físico, psicológico y social, motivo por el cual no es aceptable desde el punto de vista ético. Viola los cuatro principios de la bioética: no maleficencia, beneficencia, justicia y autonomía. Las razones que conducen a la obstinación terapéutica son: 1) la falta de un diagnóstico definitivo; 2) la falsa expectativa en el mejoramiento del paciente; 3) el desacuerdo (entre médicos y familia o entre los médicos mismos) con la situación del paciente; 4) la dificultad para comunicarse con el paciente y con la familia; 5) la conformidad con tratamientos poco realistas o fútiles; 6) barreras culturales o espirituales y 7) aspectos médico legales. La limitación del esfuerzo terapéutico (LET) es una decisión deliberada o meditada sobre la no implementación o la retirada de medidas terapéuticas que no aportarán un beneficio significativo al paciente. Pero, rechazar un tratamiento no puede implicar la aceleración artificial del proceso de la muerte. Chile no contempla en su legislación la eutanasia ni el suicidio asistido. Criterios utilizados para justificar o no, la limitación del esfuerzo terapéutico: 1) la inutilidad del tratamiento (futilidad); 2) los deseos expresos del paciente; 3) la calidad de vida y 4) el costo económico. El Comité de Ética Asistencial del Hospital de Urgencia Asistencia Pública, ha elaborado una Guía Clínica de LET. Propone un flujograma de toma de decisiones que considera la autonomía del paciente, la postura tanto del equipo médico, del paciente y su familia y en caso de no acuerdo, del comité de Ética Asistencial.

Condutas de limitação terapêutica em pacientes internados em Unidade de Terapia Intensiva / Therapeutic limitation conducts in intensive care unit patients

JUSTIFICATIVA E OBJETIVOS: Atualmente, há uma tendência crescente de se buscar o "morrer com dignidade", mais do que prolongar inutilmente o sofrimento de pacientes terminais em unidades de terapia intensiva (UTI). O objetivo deste estudo foi avaliar a utilização de condutas que sugerem limitação terapêutica (LT) em pacientes que foram a óbito em UTI Adulto. MÉTODO: Trata-se de um estudo exploratório, retrospectivo, que avaliou prontuários médicos de pacientes que foram a óbito na UTI geral de um hospital privado de Salvador-BA, entre janeiro e agosto de 2003, com internação superior a 24 horas na unidade. Os pacientes foram classificados, em relação ao óbito, em "não resposta a medidas de reanimação", "morte encefálica", "decisão de não reanimar" (DNR), "não adoção ou retirada de medidas de suporte de vida", sendo estas duas últimas consideradas medidas sugestivas de limitação terapêutica. RESULTADOS: Foram incluídos dados referentes a 67 pacientes, correspondendo a 90,4 por cento dos pacientes falecidos na unidade durante o período. Destes, 56,7 por cento eram mulheres e a idade média dos pacientes foi de 66,58 ± 17,86 anos. Medidas sugestivas de LT foram encontradas em 59,7 por cento dos pacientes, sendo a mais importante "não adoção de medidas de suporte" (35,8 por cento), seguida de DNR (17,9 por cento) e "retirada de medidas de suporte" (6 por cento). A utilização de fármacos vasoativos e métodos dialíticos foram as medidas de suporte mais omitidas, enquanto antibioticoterapia foi a mais retirada. A utilização de medidas de LT foi mais freqüente nos pacientes clínicos. CONCLUSÕES: Os dados do presente estudo sugerem altas freqüências de condutas médicas sugestivas de LT em UTI geral no Nordeste do Brasil. Métodos terapêuticos que possam causar desconforto ou sofrimento aos pacientes terminais, como nutrição, sedação e analgesia, raramente foram omitidos ou retirados.

BACKGROUND AND OBJECTIVES: There is a growing tendency of looking for "dying with dignity", rather than to prolong death and suffering of terminal patients on intensive care units (ICU). This study aims to evaluate medical practices that suggest therapeutic limitation (TL) in patients who died in an adult ICU. METHODS: A retrospective exploratory study was carried out to evaluate medical records of patients who died in a general adult ICU of a private hospital in Salvador-BA, between January and August of 2003, after at least 24 hours from the admission. The patients were classified, in relation to their deaths, in: "not responding to cardiopulmonary resuscitation", "brain death", "decision not to resuscitate" (DNR) and "withhold or withdrawal life-support measures". RESULTS: Sixty seven patients were included, corresponding to 90.4 percent of the deaths occurred in this ICU during the referred period. The most of them (56.7 percent) were women and the patientsÆ mean age was 66.58 ± 17.86 years. Suggestive measures of TL were found in 59.7 percent of the patients, being "withhold of life-support measures" the most important (35.8 percent), followed by DNR (17.9 percent) and "withdrawal of life-support measures" (6 percent). The procedures most commonly omitted were use of vasoactive drugs and dialysis, while antibiotics were the most discontinued. The use of TL measures was more frequent in clinical patients. CONCLUSIONS: The results of the present study suggest high frequencies of medical conducts suggestive of TL in a general ICU in Northeast of Brazil. Therapeutic methods that could cause discomfort or suffering to the patients, as nutrition, sedation and analgesia, were rarely omitted or discontinued.

La reanimación cardiorrespiratoria y la orden de no reanimar / Cardiopulmonary resuscitation and do not resuscitate orders

In medical practice, the different scenarios in which cardio respiratory resuscitation (CPR) may be applied must be taken into account. CPR is crucial in subjects that arrive in emergency rooms or suffer a cardiac arrest in public places or at their homes. It is also critical in hospitalized patients with potentially reversible diseases, who suffer cardiac arrest as an unexpected event during their evolution. In intensive care units, the decision is particularly complex. The concepts of therapeutic proportionality, treatment futility and therapeutic tenacity can help physicians in their decision making about when CPR is technically and morally mandatory. The do not resuscitate (DNR) decision in taken when a patient is bearing an irreversible disease and his life is coming to an end. DNR decisions are clearly indicated in intensive care units to limit the therapeutic effort and in other hospital facilities, when death is foreseeable and therapeutic tenacity must be avoided. DNR orders must be renewed and reconsidered on a daily basis. It does not mean that other treatment should be discontinued and by no means should the patient be abandoned. DNR and previous directives, DNR and quality of life and DNR communication are also commented in the present article.
