I also find that the quinine been heretofore administered to the patient by small amount of other solvents, such as ethyl rectal instillation for obtaining analgesia; howalcohol, and when so used, I find that approxiever, as previously stated, this administration mately three fluid drains of ethyl alcohol in a cannot be applied with success to the patient unfour fluid ounce solution of the compound is sufiitil after the first stages of labor have passed becient for all purposes of solubility. cause of the short duration of its eflect. I am I have found that a mixture of 1 ounces also aware that barbiturates have been used with mineral oil, 2 ounces ether, 20 grains quinine inhalation anaesthetics. I believe the use of the alkaloid, together with a mixture of two barbitubarbiturates in the manner which I am about to rates which are known to the profession as disclose, is distinctly new. There are at the presnembutal (acid form) and neonal, which barbi- 190 ent time, a number of commercial barbiturates, u a s a et y (l-mcthyl y barbitulic some of which better suit themselves than others, acid, and n-butyl ethyl barbituric acid respecto my particular compound.

In the foregoing example ethyl (lmethylbutyl) barbituric acid is representative of a quick acting barbiturate which takes effect very shortly after administration, whereas the other is representative of a relatively slow acting barbiturate which in this instance may involve twice as much time before it becomes effective. This mixture may be administered as previously described and is particularly adaptable for analgesia during childbirth. Upon instillation of the above dosage, the average patient is susceptible to from 10 to 18 hours of complete amnesia and analgesia.
A compound made in accordance with my invention, from which the quinine is omitted may also be used for surgery. A particular combination for such use may be 2% ounces ether, 1%; ounces mineral oil and 10 grains of nembutal. It is very apparent-that the increased proportions of the barbiturate will give more complete anaesthesia. The dosage may be regulated according to body Weight, a patient weighing 130 pounds or over receiving the full 4 ounce mixture; those between 100 and 130 pounds receiving approximately of the contents and those under 100 pounds receiving /2 of the contents.
In actual use it has been found that the patient usually becomes drowsy within 30 minutes and gradually goes into a deep slumber. In time, (1 hour) most patients can be aroused but with great difliculty and the uterine contractions appear to be accelerated rather than interfered with. The dosage of the barbiturates may in some cases be regulated in such a manner that a supplemental anaesthesia may be required. The use of a compound as described, eliminates the use of drugs which may seriously afiect the baby or patient. It will also reduce the post operative need of narcotics. The pulse, respiration and blood pressure are not materially affected. The blood loss is not affected. Uterine contractions are not interfered with and the patient has no recollection of labor pains. No undesirable after effects have been observed.
Having thus described my compound and its method of use, I am aware that the exact proportions of the various ingredients may be varied, and should be varied to suit different cases, but
that such variation is well within the precepts of the invention and such as may be understood to those experienced in such matters and does not depart from the spirit of myinvention nor the scope of the appended claims.
I claim:
1. A hypnotic compound for rectal instillation comprising a solution of oil, ether and a barbiturate.
2. A hypnotic compound for rectal instillation comprising a mixture of oil and ether and an oil and ether soluble barbiturate.
3. A hypnotic compound for rectal instillation comprising a mixture of mineral oil and ether and an oil and ether soluble barbiturate.
4. A hypnotic compound for rectal instillation comprising a mixture of mineral oil and ether and a barbiturate.
5. A hypnotic compound for rectal instillation comprising a mixture of oil, ether and two or more of the barbiturates.
6 A hypnotic compound for rectal instillation comprising a mixture of oil, ether and oil and ether soluble barbiturates.
7. A hypnotic compound for rectal instillation comprising a mixture of oil, ether, and ethyl (1-methyl butyl) barbituric acid-and n-butylethyl-barbituric-acid.
8. A hypnotic compound for rectal instillation comprising a mixture of mineral oil, ether and ethyl (l-methyl butyl) barbituric-acid.
9. A-hypnotic compound for rectal instillation comprising a mixture of mineral oil, ether and n-butylethylbarbituric-acid.
10. A hypnotic compound for rectal instillation comprising a mixture of mineral oil, ether and ethyl (l-methyl butyl) barbituric-acid and n-butyl-ethyl-barbituric-acid.
11. An analgesic comprising a mixture in the proportions-mineral oil 1 /2 ounces, ether 2%; ounces, and ethyl (l-methyl butyl) barbituricacid 8 grains and n-butyl-ethyl-barbituric-acid
