Nitrous oxide-oxygen: a new look at a very old technique.
نویسندگان
چکیده
Inhalation sedation utilizing nitrous oxide-oxygen has been a primary technique in the management of dental fears and anxieties for more than 150 years and remains so today. Though other, more potent, anesthetics have been introduced, nitrous oxide is still the most used gaseous anesthetic in the world. Administered properly with well-maintained equipment, the nitrous oxide-oxygen technique has an extremely high success rate coupled with a very low rate of adverse effects and complications.

متن کاملThe effect of various concentrations of nitrous oxide on the 24-hour explanted chick embryo.
The effects of nitrous oxide on the early explanted chick embryo were investigated using the technique of New (1955). After 22 hours incubation the embryos were explanted and exposed for a further 24 hours to the following gases: air, nitrous oxide (25 per cent), nitrous oxide (60 per cent), nitrous oxide (79 per cent). The oxygen concentration was maintained at normal levels (20.9 per cent) an...
متن کاملComparative evaluation of stress levels before, during, and after periodontal surgical procedures with and without nitrous oxide-oxygen inhalation sedation
Context Periodontal surgical procedures produce varying degree of stress in all patients. Nitrous oxide-oxygen inhalation sedation is very effective for adult patients with mild-to-moderate anxiety due to dental procedures and needle phobia. Aim The present study was designed to perform periodontal surgical procedures under nitrous oxide-oxygen inhalation sedation and assess whether this tech...
متن کاملTranscutaneous 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/...

Nitrite and nitrous oxide made up 40% of the hypolimnetic dissolved inorganic nitrogen in mesotrophic Lake Rotoiti, New Zealand, prior to hypolimnetic anoxia. Up to 120 mg of N m-3 as nitrite and 20 mg of N m-3 as nitrous oxide accumulated, whereas dissolved-oxygen concentrations remained between 1.0 and 0.2 g m-3 and were totally consumed when the hypolimnion became completely anoxic. Assays o...
