Abstract
We measured their dust production, acceptability of colour indicator, and CO(2) absorption capacity in in vitro experimental settings and the concentration of compound A in an inspired anaesthetic circuit during in vivo clinical practice. In vitro, the order of the dust amount was Sodasorb LF > Medi...

Abstract
The 8-h TWA (n = 36) nitrous oxide concentrations varied between 2.5 and 260 mg/m3, and the geometric means for all the 8-h TWAs was 17 mg/m3 for the midwives and 42 mg/m3 for the assistant midwives. Around 25% of all the 8-h TWAs exceeded the American Conference of Industrial Hygienists' (ACGIH) th...

Abstract
Ozone application cycles with displacements showed significantly higher leakage levels than continuous complete cycles. The largest ozone delivery cups showed the highest leakage values. A change in background levels was seen with similar change in adjacent ozone levels. The overall measured ozone l...

Abstract
Chronic exposure to elevated ambient air levels of nitrous oxide during nitrous oxide/ oxygen (N2O/2) sedation can result in deleterious side effects to dentists and auxiliary staff. A sampling survey was done in the outpatient dental clinic at the Hospital for Sick Children to determine whether air...

Abstract
N(2)O levels in excess of the occupational exposure limit (OEL) value of 180mg/m(3) were registered in all ORs equipped with ventilation systems alone. The OEL value was exceeded several times in rooms with natural ventilation plus supplementary pressure ventilations and twice or less in those with...

Laboratory Animals (40)2 2006
Abstract
We have shown that isoflurane exhaust from passive gas-scavenging canisters is often quite high when using conventional rodent anaesthesia protocols and equipment. Another likely source of WAG build-up in rodent procedure rooms is leakage at the interface between the breathing circuit and the animal...

Abstract
In the present setting, isoflurane via the ACD is an environmentally safe method of sedation provided users follow instructions for standardizing procedures with potential spillage of isoflurane. This method of sedation requires considerably less isoflurane than with traditional vaporizer technique....

Abstract
The mechanism for the reaction between nitric oxide (NO) and O(2) bound to the heme iron of myoglobin (Mb), including the following isomerization to nitrate, has been investigated using hybrid density functional theory (B3LYP). Myoglobin working as a NO scavenger could be of importance, since NO rev...

We evaluated the exposure of paediatric anaesthetists to nitrous oxide and sevoflurane as assessed by personal environmental and biological samples. The influence of venue and technique, and the strength of the relationship among the various sampling techniques were analysed. The study found that ex...

Abstract
The laminate consisted of several polymer layers, aluminium, and one cellulose-based layer containing the active enzymatic system (e.g., glucose oxidase, catalase, glucose, and CaCO3). During the industrial lamination process, the enzyme layer was exposed to three temperature spikes up to 325 degree...

Clinical evaluation of the efficacy of three nitrous oxide scavenging units during dental treatment.
Abstract
There are environmental health concerns for dental health care providers chronically exposed to trace amounts of waste nitrous oxide (N2O). This study compared the effectiveness of three N2O scavenging systems, the Porter/Brown, the Accutron, and the Matrx, in actual time during use in a standardize...

Abstract
In 79.2% of the trials the participants could smell halothane when the pump from the scavenger system was not operational. However, when the pump was switched on, halothane was detected only 16.7% of the time (P < 0.001). CONCLUSION: We have developed a simple and effective method of delivering inha...

Abstract
We report the in vitro longevity of a conventional soda lime carbon dioxide absorbent and an absorbent free from strong alkali (Amsorb). Although the times taken to breakthrough of carbon dioxide (> 0.5%) within an in vitro low flow breathing system were shorter with the alkali-free absorbent, we fo...

Abstract
Occupational exposure to nitrous oxide and halothane or isoflurane was lower in 1997 compared with that of 1996. In 1996, 89% of the nitrous oxide values were above the European threshold value of 100 ppm, whereas in 1997 approximately 50% were above this limit. In 1996 the majority of the measureme...

Abstract
Open surface tanks often are used in industrial practice. When harmful substances are involved, control of worker exposure requires the use of a local ventilation system. The push-pull system, among others, involves a jet of air that is blown from one side of the tank and collected by an exhaust hoo...

We used the inner tube and its 22-mm connector from the patient end of a Bain breathing system to splint the double-ended bag of the Jackson Rees modification of the Ayre's T-piece breathing system. A paediatric airway pressure-limiting valve was connected to the distal end of the tube for closed sc...
