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...
متن کاملNitrous 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...
متن کاملNitrous Oxide-Curare Anesthesia: Reappraisal*
Of the many inhal ation drugs available today, nitrous ox ide is the only one which is both nonex plosive and non-tox ic. Although the compound is rarely listed as a primary agent , it is used on almost every patient. The usefulness of nitrous oxide tends to be dismissed because it is considered to be relatively weak. However, with the continuing trend toward lighter anesthesia see n during the...
متن کاملNitrous 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...
متن کاملClosed-loop feedback controlled administration of alfentanil during alfentanil-nitrous oxide anaesthesia.
We have studied the automatic administration of alfentanil during alfentanil-nitrous oxide anaesthesia in 11 patients using a closed-loop feedback control system based on EEG analysis. We chose a median EEG frequency of 2-4 Hz as the EEG set point. The slope of the asymptote to the cumulative dose requirement was used to define an effective therapeutic infusion of alfentanil. Median EEG frequen...
