Analgesia in Labor Becomes Respectable: The Role of John Snow

David A.E. Shephard, M.B.


In 1591, Lady Euframe MacAlyane of Edinburgh, Scotland, was bold enough to ask a midwife to relieve the pains of labor.1 So roundly was analgesia in labor condemned then that she was put to death. Physicians, of course, had long sought to relieve the pains of labor, but it was not until an event of catalytic import occurred on April 7, 1853, that opposition to labor analgesia began to fade. That event was the administration of chloroform by John Snow, M.D., to Victoria, Queen of England for childbirth. All went well, and the Queen's approval of "that blessed chloroform"2 sent the message that pain relief was acceptable, even respectable, for women in labor.

In celebrating the 150th anniversary of the use of chloroform in obstetrics, it is timely to consider how John Snow became an agent of change in the acceptability of analgesia in labor.

Objections to Analgesia in Labor

Why apparently intelligent physicians and churchmen should have objected to analgesia in labor is not easy for us to appreciate today. These objections, which raged on both sides of the Atlantic, cannot be detailed here, but the two major aspects were the opposition to anesthesia itself and the opposition to analgesia in labor.

Opponents of anesthesia had two main arguments: first, in its initial decade, anesthesia was hazardous and sometimes fatal (particularly in inexpert hands); and second, in abolishing pain, which was regarded as the main stimulator of life and healing, the manifestations of anesthesia seemed to be uncomfortably like those of death. As for analgesia in labor, pain was held to be necessary for the normal progress of labor, while churchmen (and some physicians) held that anesthesia, in abolishing the pains representing God's punishment on womankind for tempting Adam's fall, was sinful because it circumvented the chastisement inflicted by a Higher Power.

One of the first to use anesthetic agents to relieve the pains of labor was Sir James Young Simpson of Edinburgh. He gave ether as early as January 19, 1847,3 and chloroform on November 8 that year.4 He was the prime target of the anesthesia critics, who branded him as a heretic. But Simpson most capably refuted the opponents' arguments, most of which were based on an interpretation of the Bible that differed from Simpson's. Among the points he made, two are memorable.5 First, the word "sorrow" in Genesis 3:16 ("in sorrow thou shalt bring forth children") should be properly translated as meaning labor, toil or physical exertion rather than pain, so that to use the quotation as an argument against analgesia was invalid. Second, the fact that the Lord had permitted Adam to sleep while undergoing the first operation in history meant that anesthesia was surely respectable. With his agile mind and broad shoulders, the outgoing Simpson blunted the attacks of the critics and so made easier the path for his London compatriot, John Snow, to trod when he, albeit unwittingly at the time, became an agent of change in obstetric anesthesiology.

How John Snow Came to Be an Agent of Change

It was not by chance that John Snow, with Queen Victoria, became the agent of change whereby analgesia in labor became acceptable. Snow's work in anesthesia had begun at the beginning of 1847. His clinical competence, his ready understanding of the problems of the new discipline and particularly his research, conducted from 1848 to 1851,6 established him as the leader of the new discipline. Quietly and systematically, he had laid the scientific foundations of anesthesia7 long before he was called to Buckingham Palace, and the knowledge he thus gained contributed to his clinical mastery, mastery reflected in the fact that only one of his 4,000 patients died under chloroform. No one else, anywhere, was in so strong a position to rebut the few complaints and criticisms that were leveled at him and at anesthesia, and no one else was so well-fitted to be an agent of change.

The nature of Snow and his enormous contributions to medicine have been discussed elsewhere,8 and comments here will be restricted to Snow's work in obstetrics. Three points should be made. First, Snow was the "complete" physician, with a deep knowledge of medicine and the training and credentials of an internist, which were confirmed when he solved the problem of the transmission of cholera in 1854. Second, for all of his 20 years in practice, he was a general practitioner and was familiar with obstetrics, delivering many of his own patients. And, third, as his great text On Chloroform9 so clearly shows, he had an acute understanding of the anesthesiologist's role in obstetrics.

In particular, he knew when chloroform should be used to induce anesthesia (to facilitate operative procedures such as version) and when it should be used to produce analgesia (which he did in the majority of cases of uncomplicated labor). Of special note is his ability to use, equally well, his own inhaler, which he favored overall because he could accurately estimate the delivered concentration, or just a handkerchief, also with uncanny accuracy (or chloroform a la reine, so termed because this was the way he administered it to the Queen on April 7, 1853, and again on April 14, 1857). It was his preeminence, born of a profound knowledge of all aspects of anesthesia, that enabled him to help make analgesia in childbirth acceptable and, together with the Queen of England, even respectable.

Snow as an Obstetric Anesthesiologist

To highlight this commentary on Snow as an agent of change in obstetric analgesia, three excerpts are taken from the three casebooks in which he recorded the details of virtually all the cases he saw from 1848 until his death in 1858.10 Many of these records related to the anesthetics he gave, and a significant number related to the use of chloroform in childbirth.

The first excerpt is from a record of a patient he saw on November 1, 1848:

I found the os uteri thrown backwards and as large as half a crown, the head lying above the brim. The pains were irregular and distressing. I went backwards and forwards till about twelve o'clock when she was still in much the same state, the pains being increased in force and regularity and the os uteri in the same state. She was very much distressed, out of patience and wished to know if something could not be done for her relief.

Of course it could, particularly by Snow, who was much more liberal in his use of anesthesia, even in patients who were very ill. High-flown objections to analgesia in labor carried little weight with Snow; in contrast, the well-being of his patients carried a great deal of weight.

The next entry is for a patient he treated on January 24, 1849. The patient:

... complained very much of the pain ... and the administration of chloroform was commenced in small quantity with each pain with very good relief. Consciousness was not removed at first but in the second state of labour, what began about 9 when the pains were stronger, a larger quantity was given and consciousness was once or twice removed for a short time ... [She] was much pleased with the effects of the chloroform.

Snow's patients were all satisfied with the effects of chloroform. His careful administration of chloroform, tailored to the demands of his patient's condition, met with great success.

The final excerpt related to a patient Snow saw on October 20, 1853, not long after he had anesthetized Queen Victoria. His patient was ill, with:

... extensive cavities of the lungs ... [and] had been kept alive for some time by cod liver oil ... She sent me word that she was likely to want me and a little before six I was sent for ... The os uteri was about half dilated and the pain getting rather severe. The chloroform was commenced at once. The patient had a little difficulty in breathing it at first, on account of the tendency to cough, but in a few minutes she experienced and expressed, great relief from it ... Her convalescence was very favourable.

This record is a significant one, overshadowed only by the historic one of April 7, 1853. The patient was the daughter of one of the most respectable citizens in the land, the Archbishop of Canterbury. The Queen's approval of labor analgesia had undermined the disapproval of analgesia based on flimsy obstetric arguments and it stood for what childbearing women wanted. The Archbishop's approval now discounted the disapproval of the clerics' Pecksniffian arguments.

Conclusion

By 1853, objections to analgesia in labor could no longer be seriously entertained, and the provision of analgesia in labor by anesthesiologists had become respectable. As the doyen of anesthesiology, John Snow had taken the lead in this aspect of anesthesiology. By applying what he knew to be right, he helped bring about a victory for society over the dark forces of prejudice and hypocrisy.

About the Author:

Dr. Shephard's historical interest during his visits to the Wood Library-Museum as a Paul M. Wood Fellow centered on John Snow's influence on the development of anesthesia and on the influence of American anesthesiology on organized anesthesiology in Canada. As a result, Dr. Shephard published a biography of John Snow (John Snow: Anaesthetist to a Queen and Epidemiologist to a Nation - A Biography. Cornwall, PE: York Point Publishing; 1995). He is currently Chair of the Committee on Archives of the Canadian Society of Anaesthetists. On display at the Wood Library-Museum is Dr. Snow's ether vaporizer, a rare treasure described in great detail by the late Roderick Calverley, M.D., in an article published in the Proceedings of the 3rd International Symposium on the History of Anesthesia (Park Ridge, IL: WLM, 1992:91-99).
