Sodium Nitroprusside Toxicity


  • We present a 30 2-weeks-old (30 weeks and 2 days) male, twin 1, born by emergency caesarean section due to twin-twin transfusion syndrome (absent end-diastolic flow and cardiac anomaly in twin 2) presenting with hypertensive crisis on day 3.[ncbi.nlm.nih.gov]

  • This is the longest known use of sodium nitroprusside for deliberate hypotension during surgery which emphasizes the safety of this hypotensive technique, provided the total dosage of sodium nitroprusside is reasonable.[ncbi.nlm.nih.gov]

  • Sodium nitroprusside, contrary to SIL, was associated with systemic arterial hypotension and worsening of venous oxygen saturation.[ncbi.nlm.nih.gov]
  • CONCLUSION: Premedication with oral propranolol 10 mg before hypotensive anesthesia with sodium nitroprusside is safe and effective to reduce reflex tachycardia and the amount of sodium nitroprusside used.[ncbi.nlm.nih.gov]
  • […] increased by hypothermia, malnutrition, vitamin B12 deficiency, hepatic or renal impairment related to rate of infusion rather than total dose. cyanide ion combines with cytochrome C - impairment of aerobic metabolism - metabolic lactic acidosis signs: tachycardia[lifeinthefastlane.com]
  • Sodium Nitroprusside (Nipride ) Class: Potent vasodilator Actions: converts to nitric oxide, a potent vasodilator Venous dilation reducing preload Arteriolar dilation reducing afterload Triggers retention of sodium and water Minimal reflex tachycardia[shadwige.sites.truman.edu]
  • Symptoms: Cyanide toxicity is often associated with the odor of almonds on breath and can result in acidosis, tachycardia, mental status changes, and death.[openanesthesia.org]
  • Increased heart rate (tachycardia). The side effects listed above may not include all of the side effects reported by the medicine's manufacturer.[netdoctor.co.uk]
Retinal Pigmentation
  • Abstract The pathological increase in the levels of the second messenger nitric oxide (NO) in the vitreous cavity and retina leads to injury and cell death of the retinal pigment epithelium (RPE) cells and eventually may contribute to the occurrence and[ncbi.nlm.nih.gov]
Burning Sensation
  • Taken together with our previous experience, we believe sodium nitroprusside administration to be a treatment of choice for erythromelalgia, in which the constant pain and burning sensation make the patient extremely restless.[ncbi.nlm.nih.gov]


Hepatocellular Carcinoma
  • Abstract This study aims to explore which radicals dominate sodium nitroprusside (SNP)-induced cytotoxicity in human hepatocellular carcinoma (HCC) cells (HepG2 and Hep3B).[ncbi.nlm.nih.gov]


  • The diagnosis of severe delayed cerebral vasospasm refractory to conventional treatment (HHH therapy and nimodipine) was established before treatment.[ncbi.nlm.nih.gov]
  • Various treatments have been tried against ischemic complications during ergotism with varied and unpredictable results.[ncbi.nlm.nih.gov]
  • Abstract This study examined the sodium nitroprusside (SNP) toxicity to central nervous system (CNS) in treatment of patients with aortic dissection (AD).[ncbi.nlm.nih.gov]
  • Animal and human research supports that CBD and sodium nitroprusside might be effective in the prevention and treatment of psychosis in general and especially in schizophrenia.[ncbi.nlm.nih.gov]
  • A 3 hours treatment with 0.1 µM Ca2 ionophore ionomycin triggered annexin-V-binding and cell shrinkage, effects fully reversed by removal of extracellular Ca2 .[ncbi.nlm.nih.gov]


  • BACKGROUND: Pulmonary hypertension is associated with a worse prognosis after cardiac transplantation.[ncbi.nlm.nih.gov]
  • Comparison between the two groups revealed improvement in TCD velocities and GCS in the SNP group thus affecting the long-term prognosis.[ncbi.nlm.nih.gov]

  • The complex mutation of the NPPB gene might be an etiological factor of hereditary malignant hypertension, and it is associated with low sensitivity to the antihypertensive effect of sodium nitroprusside.[ncbi.nlm.nih.gov]


  • The Office of Surveillance and Epidemiology review outlines several reasons why these data cannot be used to calculate incidence of adverse events in the population.[federalregister.gov]

  • However, the pathophysiology of these anomalies has not been studied in depth.[ncbi.nlm.nih.gov]
