Background In Switzerland, right-to-die organisations assist their members with suicide by lethal drugs, usually barbiturates. One organisation, Dignitas, has experimented with oxygen deprivation as an alternative to sodium pentobarbital. Objective To analyse the process of assisted suicide by oxygen deprivation with helium and a common face mask and reservoir bag. Method This study examined four cases of assisted suicide by oxygen deprivation using helium delivered via a face mask. Videos of the deaths were provided by the Zurich police. Dignitas provided (...) protocol and consent information. Results One man and three women were assisted to death by oxygen deprivation. There was wide variation in the time to unconsciousness and the time to death, probably due to the poor mask fit. Swiss law prevented attendants from effectively managing the face mask apparatus. Purposeless movements of the extremities were disconcerting for Dignitas attendants, who are accustomed to assisting suicide with barbiturates. None of the dying individuals attempted self-rescue. Conclusions The dying process of oxygen deprivation with helium is potentially quick and appears painless. It also bypasses the prescribing role of physicians, effectively demedicalising assisted suicide. Oxygen deprivation with a face mask is not acceptable because leaks are difficult to control and it may not eliminate rebreathing. These factors will extend time to unconsciousness and time to death. A hood method could reduce the problem of mask fit. With a hood, a flow rate of helium sufficient to provide continuous washout of expired gases would remedy problems observed with the mask.

Background Most jurisdictions that allow euthanasia and assisted suicide (AS) regulate it through the medical profession. However, the extent and nature of how medicine should be involved are debated. Swiss AS practice is unusual in that it is managed by lay AS organizations that rely on a law that permits AS when done for nonselfish reasons. Physicians are not mentioned in the law but are usually called upon to prescribe the lethal medications and perform capacity evaluations.Methods We analyzed in-depth interviews (...) of 23 Swiss AS experts including ethicists, lawyers, medical practitioners, and senior officials of AS organizations for their views on AS.Results Although there was agreement on some issues (e.g., need for better end-of-life care), the interviewees’ preferred model for AS, and the nature of preferred medical involvement, varied, which we categorized into five types: preference for AS practice as it occurred prior to lay AS organizations; preference for the current lay model; preference for a modified lay model to increase autonomy protections while limiting medical AS normalization; preference for various types of more medicalized models of AS; and, ambivalence about any specific model of medical involvement. The rationales given for each type of model reflected varying opinions on how medicine’s role would likely impact AS practice and demonstrated the experts’ attitudes toward those impacts.Conclusion The dynamics within the Swiss AS regime, as reflected in the varying views of Swiss AS experts, shed light on the dilemmas inherent to medical scope and involvement in AS, which may have implications for debates in other jurisdictions.

Two right-to-die organisations offer assisted suicide in Switzerland. The specific legal situation allows assistance to Swiss and foreign citizens. Both organisations require a report of the person’s health status before considering assistance. This qualitative study explored these reports filed to legal authorities after the deaths of individuals in the area of Zurich. Health status reports in the legal medical dossiers of the deceased were analysed using content analysis and Grounded Theory. From 421 cases of assisted suicide (2001–2004), 350 reports on (...) health status were filed. Many cases contained diagnosis lists only. Other reports had more elaborate reports revealing that some physicians were aware about the patient’s death wish and the intention to solicit assisted suicide. Physicians’ attitudes ranged from neutral to rather depreciative. Few physicians openly referred the patient to the organisations and supported the patient’s request by highlighting a history of suffering as well as reporting understanding and agreement with the patient’s wish to hasten death. In the health status reports five categories could be identified. Some files revealed that physicians were aware of the death wish. The knowledge and recognition of the patient’s death wish varied from no apparent awareness to strongly supportive. This variety might be due to difficulties to discuss the death wish with patients, but might also reflect the challenge to avoid legal prosecution in the country of origin. To require comparable health status reports as requirements for the right-to-die organisations might be difficult to pursue. (shrink)
