Some observations on nitrous oxide cylinders during emptying.
In an effort to correct misunderstandings and to establish the value of nitrous oxide pressure monitors on anaesthetic machines, the decrease of pressure within the nitrous oxide cylinders has been studied under a variety of clinical conditions. Although the matter had been clarified by 1946, the teaching of several current anaesthetic textbooks is still fallacious since an almost linear fall i...
متن کاملInfrared monitoring of expired carbon dioxide tension during anesthesia with and without nitrous oxide
Recently, the utilization of infrared analysis of expired gas to monitor end-tidal carbon dioxide partial pressure (PETCO 2 ) during anesthesia has gained in popularity. In contrast to arterial blood gas analysis, PETCO 2 analysis is immediate and continuous. Mass spectrometry has also been used to measure PETCO, and has been found to correlate well with arterial carbon dioxide partial pressure...
متن کاملP110: 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 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...
