NITROUS OXID ANESTHESIA.

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...

Nitrous 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...

When nitrous oxide is no laughing matter: nitrous oxide and pediatric anesthesia.

Although often felt to be relatively innocuous, nitrous oxide can have significant metabolic effects in settings of abnormal vitamin B12 and B12-related metabolism in children. These conditions can be genetic or environmental. Symptoms may not appear until days to weeks after exposure to nitrous oxide. Although overt genetic diseases are relatively uncommon, the implications of nitrous oxide in...

Nitrous oxide as an adjunct to local anesthesia: a study.

[Middle ear pressure variations during anesthesia with nitrous oxide].

Some authors have reported that significant pressure changes occured in middle ear clefts when nitrous oxide (N2O) is inhaled during general anesthesia . In 18 adult patients without ear diseases who underwent non-otological surgery , middle ear pressure measurements were made with impedance audiometer (Teledyne TA-2C) just before and during N2O anesthesia. The results obtained were as follows:...
