(1) Every patient about to undergo a surgical operation
should have the benefit of basal narcosis in some shape
(2) At the present time Avertin is the most satisfactory
and generally applicable basal narcotic available.
(3) Avertin is invariably safe if a dosage of 1 gram
per kilogram of bodyweight be not exceeded.
(4) Morphia should not be used as a premedicament as it
is unnecessary and adds to the risk.
(5) Avertin is essentially a basal narcotic and not a
(6) The supplementary anaesthetic is of great importance
in obtaining successful after -results and a simple technique for its administration is detailed. Emphasis is laid on the use of CO₂ and oxygen after operation.
(7) Avertin may be used with advantage in obstetrics
but it is probably inferior to nembutal and chloral as
a routine anaesthetic, especially where working single-handed.
(8) Practically every surgical condition can be dealt
with under avertín. The contra-indications to its use
are according to the condition of the patient rather
than to the procedure to be adopted, with the exception
of operations on the anus and rectum, and tonsillectomy.
(9) Tonsillectomy should not be performed under avertin
unless a special technique is adopted.
(10) Certain conditions of the patient are better
treated by avertie than by other means. These are
cases of thyroid disease, diabetes, heart cases and
all patients of a particularly nervous temperaument.
(11) There is a definite .field for the use of avertie
(12) In the foregoing series of cases the results of
Avertin narcosis were uniformly satisfactory (with the
exception of the two tonsil cases mentioned above) and
post -operative complications were conspicuous by their
Though the series is small it covers many different
varieties of surgical procedure and the results obtained
have been so successful as to warrant the continued use
of the drug.
