The form of apparatus used is the same as that employed by dentists and contains both nitrous oxide and oxygen cylinders. A small nasal inhaler is best, although the ordinary mouthpiece will do very well. The gasbag attached to the tank should be kept under low pressure and, as a pain begins, the patient is told to breathe quietly, keeping the mouth closed. As a rule this sort of light inhalation serves to produce the desired analgesic effect. It is not necessary to put the patient deeply under in order to relieve the pain.

It is our custom to begin "sunrise slumber" as soon as the uterine contractions become painful. The earlier the gas is started, the more oxygen should be used. Two or three inhalations will suffice to take the "edge" off the earlier and lighter pains. When the pains grow heavier we use less oxygen and permit three or four deep inhalations just before a bearing-down pain. At the first suggestion of a contraction, the patient must begin to inhale the gas; while after the patient has pulled hard on the traction strops - just as the contraction pain is passing - she is given an inhalation containing a larger percentage of oxygen.

At the beginning of a pain, pure nitrous oxide is administered, and the patient is instructed to breathe deeply and rapidly through the nose. The gasbags should be about half filled. The mixture of gas and oxygen must be determined by the severity of the pains and individual behavior of the patient.

Four to six inhalations of the gas are sufficient to produce the required analgesia in the average case. Following the first few deep inspirations through the nose, the patient can be instructed to breathe through the mouth, while the gas is well diluted with oxygen and continued until the end of the pain. In this way a satisfactory analgesia is maintained throughout the "pain" with a minimum of "gas." The proportion of oxygen used will run from nothing up to ten percent. This procedure is repeated with the occurrence of each pain.

The use of the "mask" is just as effective as a nasal inhaler, but wastes more gas and so is more costly.

When the head is passing the perineum the gas should be pushed to the point of anesthesia, while the patient's color will suggest the amount of oxygen to be used as well as serve to control the administration of the nitrous oxide.

Chloroform and Ether

For many years chloroform and ether have been used to alleviate the pains of women in labor. Valuable as these agents are when deep anesthesia is required for the carrying out of operative procedures, they have not proved satisfactory as analgesic agents. If administered in small quantities at the commencement of a strong uterine contraction, the patient does not usually inhale sufficient to abolish pain. She is then apt to be irritated and is certain to insist on being given a larger quantity. If a sufficient amount be administered to satisfy the woman, the continued repetition gradually inhibits the power both of the uterus and of the accessory muscles, so that labor is unnecessarily prolonged, and, possibly, the life of the fetus endangered.

Physicians have, therefore, been accustomed to employ these drugs very sparingly, restricting their use to the very end of the second stage, during the painful passage of the head through the vulva. The results of the administration at this time are also uncertain. If delivery be rapid the woman may not be able to inhale sufficient to abolish her consciousness of pain. If it be slow she may take too much and weaken the muscular powers, thereby prolonging labor and, often, necessitating forceps delivery. It is not surprising, therefore, that the medical profession has long been hoping that a more satisfactory method of relieving the pain of labor would be found.

Conclusions

In summing up our conclusions regarding analgesia and anesthesia in labor cases, the authors would state their present position as follows:

1. That anesthetics or analgesics are a necessary accompaniment of confinement in this day and age; that the average labor case demands some sort of pain-relieving agent at some time during its progress; but that intelligent efforts should be put forth to limit and otherwise control their use. While we recognize the necessity for avoiding needless suffering, at the same time we must also avoid turning our women into spineless weaklings and timid babies.

2. That we should seek to develop, strengthen, and train our girls for a normal and natural maternity; that we should study to attain something of the naturalness and the painlessness of the labors of Indian tribes; and, even if we partially fail in this effort, we should at least leave our women with ennobled characters and strengthened wills.

3. That the scopolamine-morphine method of inducing "twilight sleep" has its place - in the hands of experts - and in the hospital; and that in many cases it probably represents the best method of obstetric anesthesia which can be employed.

4. That as a general rule and in general practice, the safest and best method of inducing the "twilight" state of freedom from severe pain, is by the use of nitrous oxide or "laughing gas" - the "sunrise slumber" method. It has been our practice to start all general ether anesthetics with "gas" for a number of years, while we have been doing an increasing number of both minor and major operations with "gas" alone.

5. That we still employ general ether or chloroform anesthesia in Cesarean sections and other major obstetric operations, although several operators are beginning to use "gas" in even these heavy cases.

6. That the intelligent and careful use of pituitary extract in certain cases of labor serves greatly to shorten the second stage; that it is of great value in certain "slow cases," and serves greatly to reduce the use of low forceps.

We have treated the subject of obstetric anesthesia in this full manner, because of the fact that so much has appeared in the public press on these subjects, and, further, because we desired that our readers should have placed before them the facts on all sides of the question just as fully as a work of this scope would permit.
