Cyanide and thiocyanate concentrations following sodium nitroprusside infusion in man.
Twenty-six patients, receiving an infusion of sodium nitroprusside (SNP) during surgery, had considerable increases in both red cell and plasma cyanide concentration, but only small changes in plasma thiocyanate concentration. There was a linear relationship between both plasma and RBC cyanide concentrations and the total dose of SNP. The expired cyanide concentration followed the changes in th...
متن کاملNitroprusside and cyanide.
Sir,—An otherwise excellent and thorough report by Vesey, Cole and Simpson (1976) fails to acknowledge or refute a hypothesis which has already appeared in this Journal (Smith and Kruszyna, 1976a) about the mechanism by which cyanide is released from nitroprusside in vivo, and the significance of that reaction for blood cyanide concentrations. We are delighted with the confirmation that "The re...
متن کاملEnterobius vermicularis in Cerebrospinal Fluid
Enterobius vermicularis is a nematod of large intestine in man. Extra intestinal localization of this parasite is rare. A 60 year old man was admitted to the hospital with the clinical manifestation of meningitis. In laboratory examination of cerebrospinal fluid (C.S.F), the appearance was red, Albu-min level was high and the glucose showed normal value. Haematoxylin and Eosin stained slides pr...
متن کاملAccentuated hypotensive effect of sodium nitroprusside in man after captopril.
1. The effects of graded intravenous infusions of sodium nitroprusside on resting blood pressure and heart rate and on the reflex changes in these variables evoked by a standardized Valsalva manoeuvre were studied in six normal subjects. The effects of nitroprusskle on the above variables were also studied after pretreatment with captopril, to allow assessment of the role of angiotensin 11. 2. ...
متن کاملCyanide toxicity following nitroprusside induced hypotension.
Several recently reported deaths following the use of sodium nitroprusside have been attributed to the accumulation of the nitroprusside metabolite, cyanide. In this study, brief nitroprusside infusions (mean = 36 minutes) were administered in currently recommended doses during intracranial surgery. The peak blood cyanide following the infusions was 65.2 +/- 17.5 microgram per cent (mean +/- SE...
