VINYL ETHER (VINESTHENE) ANAESTHESIA IN DOGS:

Ether anaesthesia, 1842-1900.

Thermal dissociation of ethylene glycol vinyl ether.

The pyrolysis of ethylene glycol vinyl ether (EGVE), an initial product of 1,4-dioxane dissociation, was examined in a diaphragmless shock tube (DFST) using laser schlieren densitometry (LS) at 57 ± 2 and 122 ± 3 Torr over 1200-1800 K. DFST/time-of-flight mass spectrometry experiments were also performed to identify reaction products. EGVE was found to dissociate via two channels: (1) a molecul...

The present position of ether anaesthesia.

Ether has been our good friend and trusted helper for one hundred years. But, to-day, some of our colleagues maintain that this drug should not be used, although many experienced practitioners still consider ether to be one of the best anaesthetic agents. This difference of opinion arises, I believe, because of the absence of a clear differentiation between the action of the anaesthetic drug an...

Convulsion during ether anaesthesia; a case report.

A five-year-old girl was admitted to Hammer-smith Hospital with a diagnosis of a perforated appendix. Her mother stated that she had complained of pain in the R.I.F. for 12 hours prior to admission, that during that time she had vomited periodically and was "breathing very fast." The pain had become severe in the evening and she was brought up to the Casualty Department. Physical examination re...

Preparation of vinyl chloride – vinyl ether copolymers via partial etherification from PVC

The chemical modifications of poly (vinyl chloride) with aliphatic and aromatic alcohols compounds have been investigated at room temperature and atmospheric pressure, catalysed by a new green basic catalyst, the Maghnite-K. The presence of ether groups in the products is proven by infra red spectroscopy (IR) as well as by nuclear magnetic resonance spectroscopy (1H NMR), and characterized by i...
