"Sympathectomy is a technique about which we have limited knowledge, applied to disorders about which we have little understanding." Associate Professor Robert Boas, Faculty of Pain Medicine of the Australasian College of Anaesthetists and the Royal College of Anaesthetists

Safety and Ethics in Healthcare

"...professionals may adopt unreasonable practices. Practices may develop in professions, particularly as to disclosure, not because they serve the interests of the clients, but because they protect the interests or convenience of members of the profession. The court has an obligation to scrutinize professional practices to ensure that they accord with the standard of reasonableness imposed by the law."

Incresingly, the question is not whether the defendant's conduct conforms with the practices of the profession, but whether it conforms with standards of reasonableness. (p. 150)

"The right of patients self-determination is well entrenched both in law and in ethical codes. Respect for patient autonomy now occupies centre stage in medical ethics. In considering patient autonomy one needs to think about truth telling, confidentiality, privacy, disclosure of information and consent. Each is important and all have important implications for healthcare professionals." (p. 167)

Effect of cervical sympathectomy and circulatory hypoxia on time course of prostaglandin concentration in brain tissues

Some workers suggest a possible "transmembrane" role of PG in the nervous system.


If the increase in the PG level during ischemia is regarded as a protective reaction, it must be admitted that no increase took place 1 day after CSE (cervical sympathectomy) and it was considerably weakened 7-40 days after CSE.


The effect of cerebral ischemia was virtually indistinguishable from the action of CSE itself.


It can be tentatively suggested that PGF plays the main role in the regulation of tone of the vascular wall and in the regulation of metabolism under conditions of ischemia when the sympathetic regulation is disturbed.
