Nitrous Oxid Oxygen 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...

Transcutaneous oxygen monitoring of patients undergoing nitrous oxide-oxygen sedation

The objective of this study was to assess the changes in transcutaneous oxygen tension in pediatric patients undergoing nitrous oxide-oxygen analgesia. A total of 19 healthy patients, ranging in age from 3 to 19 years with a mean age of 9.8 years, were included. Transcutaneous oxygen monitoring was performed; following stabilization, baseline readings were obtained. Oxygen was delivered at 3 I/...

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...
