Cardiovascular collapse associated with nitrous oxide administration

Nitrous oxide administration and hemodynamics.

EDITORIALS 211 inotropic agents (such as the catecholamines, calcium ions, and digitalis), and paired electrical stimulation. Entropy also increases during congestive heart failure, which may be thought of as an expression of a defect in the utilization of energy, a partial chemicomechanical uncoupling. The entropy of the myocardial cell tends to be reduced by negative inotropic agents, such as...

Nitrous oxide anesthesia-associated myelopathy.

BACKGROUND The role of nitrous oxide exposure in neurologic complications of subclinical cobalamin deficiency has been reported, but few cases are well documented. OBSERVATION Two weeks after surgery for prosthetic adenoma, a 69-year-old man developed ascending paresthesia of the limbs, severe ataxia of gait, tactile sensory loss on the 4 limbs and trunk, and absent tendon reflexes. After a s...

Polydrug abuse associated with nitrous oxide causes death

The case report byHirvioja et al. raises some interesting points [1]. Unfortunately, the title is somewhat misleading because it suggests that it was nitrous oxide alone that caused the death and ignores the likelihood, from the data presented, that the death was probably due to the other substances found in the patient’s blood aswell as the nitrous oxide [1]. As far as I am aware, there is no ...

Nitrous oxide administration using commonly available oxygen therapy devices.

Administration of nitrous oxide is useful for providing sedation and analgesia. The therapeutic range for nitrous oxide is 20-30%. Several oxygen treatment devices have been used for administering nitrous oxide, but little is known about the concentrations of nitrous oxide and oxygen delivered to the trachea. We have studied this, using an analogue lung model, with several oxygen therapy device...
