Cyclopropane anesthetic, for oral surgery with nasoendotracheal intubation

Cyclopropane fulfills all the requirements of an anesthetic agent for oropharyngeal surgery. It has a potency sufficient to carry anesthesia to a plane deep enough for relaxation of intrinsic and extrinsic muscles of the larynx with depression of reflexes. There is no anoxia or hypoxia because of an increase of 55 per cent oxygen above other gas anesthetics. The previously mentioned properties of the anesthetic agent, combined with the skill of the anesthetist, permit establishment of a controlled airway throughout the operation. The danger of aspirating foreign bodies is considerably lessened, and the anesthetist's equipment is out of the surgeon's field of operation. It has been shown through careful study and preparation of the structures involving the pharynx and larynx that a blind intubation may be successfully accomplished without trauma. The procedure for endotracheal intubation takes less than two minutes and not more than five. A rapid and pleasant induction is ensured. An established airway is maintained through adequate relaxation of the muscles.
