El tratamiento con dosis bajas de eritropoyetina no está asociado con los beneficios clínicos en los Testigos de Jehová gravemente anémicos: una súplica para un cambio.

Abstract
BACKGROUND: Jehovah's Witnesses who refuse blood transfusion have high mortality. Erythropoietin (EPO) has been used as an alternative to blood transfusion. The optimal dosing of EPO in anaemic Jehovah's Witnesses is unknown. The aim of our study was to evaluate the clinical benefits of treatment with a low dose (<600 IU/kg/week) of epoietin beta (EPO-β). MATERIALS AND METHODS: This was an observational study, retrospectively considering a 10-year period during which 3,529 adult Jehovah's Witnesses with a total of 10,786 hospital admissions were identified from databases of four major public hospitals in New Zealand. Patients with severe symptomatic anaemia (haemoglobin <80 g/L) who were unable to tolerate physical activity were included in the study. Patients treated without EPO were assigned to the conventional therapy group and those treated with EPO to the EPO treatment group. RESULTS: Ninety-one Jehovah's Witnesses met the eligibility criteria. Propensity score matching yielded a total of 57 patients. Patients treated with conventional therapy and those treated with EPO had similar durations of severe anaemia (average difference 6.25 days, 95% confidence interval [CI]: -3.77-16.27 days; p=0.221). The mortality rate among Jehovah's Witnesses treated with conventional therapy was 4.68 per year (95% CI: 2.23-9.82), while that in those treated with EPO was 2.77 per year (95% CI: 0.89-8.60). Treatment with EPO was associated with a mortality ratio of 0.59 (95% CI: 0.1-2.6; p=0.236). Both groups of patients had similar in-hospital survival (p=0.703). DISCUSSION: Treatment with low-dose EPO-β was not associated with either shorter duration of severe anaemia or a reduction in mortality.

Abstract
There are many patient groups who may refuse blood products; the most well known amongst them is the Jehovah's Witness faith. Treatment of anaemia and bleeding in such patients presents a challenge to medical, anaesthetic, and surgical teams. This review examines the perioperative issues and management of Jehovah's Witnesses. The history and beliefs of Jehovah's Witnesses are outlined together with their impact on ethics and the law, and different management options throughout the perioperative period are discussed.

El deber ético y legal de los anestesiólogos en relación con el paciente Testigo de Jehová: protocolo de atención.
Ethical and legal duty of anesthesiologists regarding Jehovah's Witness patient: care protocol.

Abstract
BACKGROUND AND OBJECTIVES: Jehovah's Witnesses patients refuse blood transfusions for religious reasons. Anesthesiologists must master specific legal knowledge to provide care to these patients. Understanding how the Law and the Federal Council of Medicine treat this issue is critical to know how to act in this context. The aim of this paper was to establish a treatment protocol for the Jehovah's Witness patient with emphasis on ethical and legal duty of the anesthesiologist. CONTENT: The article analyzes the Constitution, Criminal Code, resolutions of the Federal Council of Medicine, opinions, and jurisprudence to understand the limits of the conflict between the autonomy of will of Jehovah's Witnesses to refuse transfusion and the physician's duty to provide the transfusion. Based on this evidence, a care protocol is suggested. CONCLUSIONS: The Federal Council of Medicine resolution 1021/1980, the penal code Article 135, which classifies denial of care as a crime and the Supreme Court decision on the HC 268,459/SP process imposes on the physician the obligation of blood transfusion when life is threatened. The patient's or guardian's consent is not necessary, as the autonomy of will manifestation of the Jehovah's Witness patient refusing blood transfusion for himself and relatives, even in emergencies, is no not forbidden.

Abstract
INTRODUCTION: A bloodless surgery can be desirable also for non Jehovah's witnesses patients, but requires a team approach from the very first assessment to ensure adequate planning. PRESENTATION OF THE CASE: Our patient, a Jehovah's witnesses, was scheduled for right lower lobectomy due to pulmonary adenocarcinoma. Her firm denies to receive any kind of transfusions, forced clinicians to a bloodless management of the case. DISCUSSION: Before surgery a meticulous coagulopathy research and hemodynamic optimization are useful to prepare patient to operation. During surgery, controlled hypotension can help to obtain effective hemostasis. After surgery, clinicians monitored any possible active bleeding, using continuous noninvasive hemoglobin monitoring, limiting the blood loss due to serial in vitro testing. The optimization of cardiac index and delivery of oxygen were continued to grant a fast recovery. CONCLUSION: Bloodless surgery is likely to gain popularity, and become standard practice for all patients. The need for transfusion should be targeted on individual case, avoiding strictly fixed limit often leading to unnecessary transfusion.
