P110: Nitrous Oxide and Neuroinflammation
Nitrous oxide was an anaesthetic gas that was used for many years. There were many anaesthetic drugs in operations with many side effects. Nitrous oxide had some side effects too. But it was a safe gas in many times. In hospital personnel who worked in operating rooms exposure to this gas was important. The objective of this study was the introduction of nitrous oxide and neurologic side ...
متن کاملThe Nitrous Oxide Test
The diagnosis of a left-to-right shunt generally depends upon the demonstration of significant differences in oxygen content among the venae cavae, the chambers of the right heart, and the pulmonary artery. The inconclusive or misleading results sometimes obtained with this method have stimulated interest in improved technics. The wide arteriovenous difference that normally exists during the in...
متن کاملNitrous Oxide: Effects on the Mitotic Apparatus and Chromosome Movement in Hela Cells
When HeLa cells were grown in the presence of nitrous oxide (N(2)O) under pressure (80 lb/in(2)) mitosis was inhibited and the chromosomes displayed a typical colchicine metaphase (c-metaphase) configuration when examined by light microscopy. When the cells were returned to a 37 degrees C incubator, mitosis was resumed and the cells entered G(1) synchronously. Ultrastructural studies of N(2)O-b...
متن کاملThe Measurement of Uptake of Nitrous Oxide by Pneumotachography. I. Apparatus, Methods and Accuracy.
A method of measuring the breath-by-breath uptake of nitrous oxide by the pulmonary capillary blood is described. With defined reservations, this uptake is given by the difference between the tidal volumes inspired and expired. The tidal volumes were measured by pneumotachography. The accuracy of these measurements is discussed. Precautions taken to reduce errors are described, with particular ...
متن کاملNitrous Oxide Genotoxicity
1258 June 2013 NITROUS oxide has long been known to be an impotent and unpredictable human anesthetic.1 In this issue of the journal, Chen et al.2 report that nitrous oxide in clinical use is a potent and predictable human genotoxin. The authors observe that maintenance of anesthesia with 70% nitrous oxide and sevoflurane in patients undergoing colorectal surgery doubles the incidence of DNA da...
