Debout used a solution in syrup, increasing doses till the hypnotic
effect was produced (after 1/2 grain); 4,
Harley, effects of 3/4 grain, subcutaneously, in Samuel M., perfectly
well, with the exception of facial neuralgia; 5,
Harley, in John L., effects of 1 grain subcutaneously; 5a, same,
effects of 0.2 grain; 5b, same, effects of 0.4 grain.
STOMACH.
►
Loss of appetite (in some cases), [2].
► Nausea (in some cases), [2]. ►
Vomiting is rare, [2].
STOOL.
►
In small doses it is a gentle aperient; in larger doses it causes diarrhœa,
[2]. ►
The repeated use of internal doses often produces from one to two
stools, sometimes even diarrhœa, [1].
URINARY ORGANS.
►
Passed, without the least difficulty, 3ivss. of normal urine, sp. gr.
1020; this had been secreted since the injection (after two hours and a
quarter), [4]. ► When the dose exceeds 3/4 of a grain, it
causes some dysuria, [3]. ► Anuria, to a greater or less extent,
particularly after rather large doses, [2].
SEXUAL ORGANS.
►
It retards the appearance of the menses, [1].
RESPIRATORY ORGANS.
[10.] ►
Respiration 20 (before taking); 19 (after forty-five minutes); 17 (after
two hours and a quarter), [4].
PULSE.
►
Diminution of the pulse, succeeded some time after by an acceleration;
in rare cases, the pulse is accelerated during its employment by 12 to
16 strokes in a minute, [1]. ► Pulse 72 (before taking); unchanged
(after forty-five minutes); 70 (after two hours and a quarter), [4].
GENERAL SYMPTOMS.
►
A calm, comfortable feeling, with a slight tendency to sleep, continued
for four or five hours (after a quarter of an hour), [5]. ► The
same comfortable tranquillizing effect, and at the end of an hour a
little sleepiness, which soon passed off, [5b].
► A pleasant quieting effect, hardly
amounting to sleepiness, [5a].
SKIN.
►
A tender swelling at the seat of puncture, [4]. ► Its
action of the cutaneous nervous system appears to resemble that of other
narcotics, and produces its effects directly when used hypodermically,
and indirectly, by acting on the centre, when given internally, [1]. ►
The hypodermic tumor soon disappeared; the injected part remained tender
and a little puffy, for two days, [5].
► When used hypodermically it
produced a sensation of burning at the place of puncture, but of little
intensity and duration, a sensation in every case less evident than that
caused by every other alkaloid (morphia, quinia, etc.); in patients with
sensitive skins, when the injections was made on the face, it produced
an œdematous swelling without redness at the place of puncture, which
disappeared in from one to two days, leaving a somewhat sensitive and
limited induration, [1].
SLEEP.
[20.]
► A slight narcotic effect, [1]. ►
Of all the alkaloids contained in Opium, Narcein possesses hypnotic
power to the greatest extent; in the great majority of cases, neither
Morphia nor Codeia produced so long or so profound a sleep, [2]. ►
The sleep is calm and interrupted by the least noise; but one goes to
sleep again immediately; on awaking there is freedom from the heaviness
of the head experienced after the use of Morphia, and there is less
liability to vomiting and constipation; the whole of the effect is
limited to a somniferous influence, and its calming and hypnotic effects
are superior to those of Codeia, and
almost equal to those of Morphia, [3]. ►
Felt comfortable and sleepy (after fifteen minutes); very sleepy, but
had not slept (after forty-five minutes); the same kind of sleepiness as
after Morphia; had slept a quarter of an hour, and was still sleepy
(after two hours and a quarter); he walked home, a distance of two
miles, and as it was 11 P.M., went to bed and slept soundly, [4]. ►
When given internally or externally for pain, it often produces a sleep
of four, five, or even nine hours, a sleep which is soft, tranquil,
uninterrupted, and followed by a quiet waking, [1]. ► Narcein
causes, only in a very feeble degree, the physiological phenomena
consequent upon the sleep produced by Morphia and the salts of that
base, [2].
FEVER.
►
Perspiration is much less abundant than after the use of opiates, [2].® 2000
