https://www.researchgate.net/public...a_Due_To_Intentional_Sodium_Nitrite_Poisoning . судя по всему я ошибался. массивное поражение головного мозга после отравления СН вполне вероятно. если только не начали откачивать в течении первого часа и какого то времени после этого. спасибо за поправку:
"We report a case of fatal methaemoglobinaema resulting from sodium nitrite poisoning. A 28 year old woman arrested in the emergency department following collapse. During resuscitation a venous blood gas revealed a methaemoglobin percentage of 81%. Following treatment with methylene blue, sodium bicarbonate and adrenaline, the methaemoglobin decreased. Prior to transfer to intensive care, a CT head revealed extensive hypoxic brain injury. Two days later brain death was confirmed on brainstem testing. Severe methaemoglobinaemia is rapidly fatal, with fast diagnosis and treatment associated with improved outcomes."
"Case History. A 28 year old woman was brought into the emergency
department cyanosed and in cardiac arrest. She was
found collapsed in a park with a note detailing that
she had ingested an unknown quantity of sodium
nitrite (obtained from an online supplier) at up to
six hours prior for the purposes of ending her life.
With the ambulance service she was unconscious
and cyanosed, with vital signs reflected peri-arrest
(hypotension, sinus tachycardia, hypoxia and cool
peripheries"
хотя значительное отмирание мозга наступило 6 часов спустя. так что в плане "остаться овощем" этот метод "безопаснее" инертных газов или повешения.
