Objectives:

To compare current obstetric analgesia concepts and methods with those existing 100 years ago, when Anesthesia & Analgesia (1922) and British Journal of Anaesthesia (1923), the first two independently published anesthesia journals, were first published.

Methods:

We identified and analyzed all articles related to obstetric analgesia published in these journals during the years 1922 and 1923 and compared them with current clinical practice. We also searched these issues for indirect references to the attention given to obstetric analgesia at scientific meetings of the time.

Results:

In the first issue of Anesthesia & Analgesia, appearing in August 1922, 3 of the 8 articles published are related exclusively to obstetric anesthesia and analgesia, and between 1922 and 1923 we found a high number of articles and references. The analysis of these articles published a century ago allows us to objectify the interest of the time in the results, the comparison between different anesthetic methods, safety and the dissemination of scientific knowledge. References to mortality, complications, patient comfort and satisfaction, the influence of obstetric analgesia on the duration of labor, as well as savings in time and anesthetic gases are common.

It is obvious that today's research methodology cannot be compared with that of 100 years ago. But there are many scientific aspects that laid some of the foundations of current research in obstetrics, including the collection of large series of patients over long periods of time, the express mention of the publication of both favorable and unfavorable results, the references not only to cost but also to cost-effectiveness, as well as the use of specific parameters to measure not only results but also patient satisfaction.

Conclusions:

It is evident that over the years the outcomes in the practice of anesthesiology have improved, but also that many concepts remain the same 100 years later. The high number of articles published between 1922 and 1923 reflects the interest that existed a century ago in obstetric analgesia, and leads us to think that it may have been an important line of research in the specialty at that time.
