Overcoming Obstacles: The Legacy of Fidel Pagés, Founder of the Epidural, 100 Years After His Passing.

Fidel Pagés, a Spanish surgeon, tragically died in 1923 at the age of 37, just 2 years after his publication "Anestesia Metamérica," the first description of human thoracolumbar epidural anesthesia. In the intervening 100 years, epidural anesthesia has faced countless obstacles, starting with the dissemination of his initial report, which was not widely read nor appreciated at the time. However, the merits of the technique have fueled innovations to meet these challenges over the years. Even today, while epidural anesthesia is widely embraced, particularly in obstetric and chronic pain medicine, the pressures of the operating room for efficiency and a low tolerance for failure, pose modern-day challenges. Here, we revisit Pagés' original report and highlight the key innovations that have allowed for the evolution of this essential anesthesia technique.

Génesis y evolución de la anestesia epidural lumbar en su primer centenario / Genesis and evolution of lumbar epidural anesthesia in its first century

Introducción: La anestesia epidural lumbar es la técnica predilecta para gran número de anestesiólogos. Permite variadas intervenciones quirúrgicas, es útil para el tratamiento del dolor agudo y crónico, a la vez provee al paciente de distintos beneficios. También resalta su versatilidad ya que puede combinarse con otros métodos anestésicos, así como extenderla para el alivio del dolor posoperatorio. Objetivo: Describir los adelantos científicos que propiciaron la aparición de la anestesia epidural lumbar y cuál ha sido la evolución de esta técnica anestésica a lo largo de un siglo. Desarrollo: El acceso por vía lumbar al espacio epidural con fines anestésicos fue publicado por el cirujano español Fidel Pagés en marzo de 1921, luego de una década en el olvido fue introducida por el cirujano italiano Archile Dogliotti en 1931. A partir de entonces, se le han incorporado diversos y valiosos adelantos. Conclusiones: La anestesia epidural lumbar fue descrita hace un siglo por el doctor Pagés. Han sido variados y numerosos los aportes que han recibido, algunos de los cuales han sido objeto de controversias; no obstante, se ha tornado una técnica universal que sigue captando la preferencia de muchos anestesiólogos(AU)

Introduction: Lumbar epidural anesthesia is the technique preferred by a great number of anesthesiologists. It allows performing several surgical interventions and is useful for the treatment of acute and chronic pain; at the same time, it provides the patient with different benefits. It ls also worth highlighting its versatility, since it can be combined with other anesthetic methods, as well as to be extended for postoperative pain relief. Objective: To describe the scientific advances that led to the appearance of lumbar epidural anesthesia and what has been the evolution of this anesthetic technique over a century. Development: the Spanish surgeon Fidel Pagés published lumbar access to the epidural space for anesthetic purposes in March 1921. After a decade in oblivion, the Italian surgeon Archile Dogliotti introduced it, in 1931. From then on, it has been incorporated several valuable advances. Conclusions: Dr. Pagés described lumbar epidural anesthesia a century ago. The contributions achieved have been varied and numerous, some of which have been the subject of controversy; however, it has become a universal technique that continues to capture the preference of many anesthesiologists(AU)

The Historical Development of Obstetric Anesthesia and Its Contributions to Perinatology.

Scottish obstetrician James Young Simpson first introduced the use of ether and chloroform anesthesia for labor in 1847, just 1 year after William Morton's first successful public demonstration of ether anesthesia at the Massachusetts General Hospital. The contemporaneous development of surgical anesthesia and obstetrics enabled obstetric anesthesia to address the pain of childbirth. Shortly after its introduction, obstetricians raised concerns regarding placental transport, or the idea that drugs not only crossed the placenta, but exerted detrimental effects on the neonate. The development of regional anesthesia and clinical work in obstetric anesthesia and perinatology addressed issues of the safety of the neonate, enabling obstetric anesthesia to safely and dramatically reduce the pain of childbirth.

Ryszard Rodzinski-A Forgotten Polish Inventor and Pioneer of Combined Spinal-Epidural Anesthesia.

Dr. Ryszard Rodzinski was a Polish surgeon who, in spite of his short life, had a productive career. His most important discovery was a safer method of performing regional anesthesia for abdominal surgery. The first description of combined spinal epidural anesthesia is generally attributed to Soresi in 1937. In the early 20th century, Rodzinski invented a novel technique, "combined lumbosacral anesthesia," which combined lumbar spinal anesthesia and sacral epidural anesthesia. During the 19th Meeting of Polish Surgeons in July 1922 in Warsaw, Rodzinski presented an article entitled "On Combined Lumbosacral Anaesthesia," in which he described this technique used in surgical clinic in Lwów since October 1921. Given this presentation, Rodzinski could be considered to have made the first known presentation of the combined spinal and epidural anesthesia.

A personal history of the MASTER Trial and its link to the clinical trials network of the Australian and New Zealand College of Anaesthetists.

The aim of this paper is to link the history of the Multicentre Australian Study of Epidural Anaesthesia in high risk surgery, the MASTER Trial, the first National Health and Medical Research Council (NHMRC) funded multicentre randomised clinical trial in Australia led by anaesthetist researchers, and the decision of The Australian and New Zealand College of Anaesthetists (ANZCA) to establish a clinical trials network, in 2003, to the success of contemporary researchers in Australia and New Zealand in anaesthesia and perioperative medicine.

[History and Technique of Epidural Anaesthesia]. / Epiduralanästhesie - Geschichte und Technik der Epiduralanästhesie.

In 1901, the first Epidural anesthesia via a caudal approach was independently described by two FrenchmanJean-Anthanase Sicard and Fernand Cathelin.. The Spanish military surgeon, Fidel Pagés Miravé, completed the lumbar approach successfully in 1921. The two possibilities for identification of the epidural space the "loss of resistance" technique and the technique of the "hanging drop" were developed by Achille Mario Dogliotti, an Italian, and Alberto Gutierrez, an Argentinean physician, at the same time. In 1956 John J. Bonica published the paramedian approach to the epidural space. As early as 1931 Eugene Aburel, a Romanian obstetrician, injected local anaesthetics via a silk catheter to perform lumbar obstetric Epidural analgesia. In 1949 the first successful continuous lumbar Epidural anaesthesia was reported by Manuel Martinez Curbelo, a Cuban. Epidural anaesthesia can be performed in sitting or lateral position in all segments of the spinal column via the median or paramedian approach. Different off-axis angles pose the challenge in learning the technique.

Epidural catheter design: history, innovations, and clinical implications.

Epidural catheters have evolved during the past several decades, as clinicians and manufacturers have sought to influence the quality of analgesia and anesthesia and reduce the incidence of catheter-related complications. This evolution has allowed a transformation from single-shot to continuous-infusion techniques and resulted in easier passage into the epidural space, more extensive medication distribution, and ultimately, improved patient satisfaction. Particular catheter features, including the materials used, tip design, and orifice number and arrangement, have been associated with specific outcomes and provide direction for future development.

From the Journal archives: Epidural anesthesia in young children: what have we learned in the past 60 years?

UNLABELLED: Francis G. Ruston MD CITATION: Ruston FG. Epidural anaesthesia in infants and children. Can Anaesth Soc J 1954: 1: 37-44. PURPOSE: The author describes the use of single-shot epidural anesthesia in a series of 44 infants and children. The patients were anesthetized in hospitals in Hamilton, Ontario from 1949 until the time of publication in 1954. The study aimed to describe the indications and efficacy of this technique as well as any apparent complications. A detailed description of the management of these patients was given, including many tips and suggestions that are still applicable in 2013. PRINCIPAL FINDINGS: Seventy-seven infants and children received epidural anesthesia for a variety of procedures, particularly for pyloric stenosis. Forty-four of the procedures were carried out by the author. All patients survived, apart from one child who died of recurrent intestinal obstruction unrelated to the anesthetic. It was found, after some experience, that the sitting position was preferable for epidural needle insertion. Use of the hanging drop technique for identification of the epidural space proved to be simple and reliable. Surgical conditions were found to be excellent and relaxation was profound; however, some sedation was often required to obtain optimal conditions for surgery. The surgeons became sold on the technique and began to request an epidural on a regular basis. CONCLUSIONS: Epidural anesthesia in infants and young children is effective for a variety of procedures below the diaphragm, even in moribund patients.

The historical narrative: tales of professionalism?

The historical narrative is a story told to illustrate a point, however subconsciously. The "giants" of obstetric anesthesia -- Simpson, Snow, Apgar -- and countless other less well-known physicians all contributed to the history of obstetric anesthesia. We remember them by retelling this history to illustrate elements of professionalism and how we as a profession wish to act. The Physician Charter is an excellent first approximation of a workable definition of this quality, which can and does change over time. By using the three principles and 10 professional responsibilities as a template, the past comes alive as a teaching method to each and every obstetric anesthesiologist.

[History of rachianesthesia and epidural anesthesia in Spain]. / Historia de la raquianestesia y de la anestesia epidural en España.

OBJECTIVES: To show the beginning of spinal and epidural anesthesia in our country and the contributions of Spanish urologists. METHODS: We reviewed books and writings of History of Medicine, Urology and Anesthesia and Doctoral thesis about spinal and epidural anesthesia. RESULTS: In the 20th century, surgeons also gave the anesthetic drugs to the patients. Spinal and epidural anesthesia were used for the first time in 1900. A lot of Spanish urologists like F Rusca Doménech, J.M. Batrina, M. Barragán Bonet, R. Lozano Monzón, L. Guedea Calvo, Gil Vernet, Fidel Pagés Miravé, V Sagarra Lascurain, Gómez Ulla, etc, did research, writings in scientific journals and Doctoral thesis about anesthesia.

[Development and current status of combined spinal epidural anaesthesia]. / Entwicklung und gegenwärtiger Stand der kombinierten Spinal-Periduralanästhesie.

Combined spinal and epidural anaesthesia/analgesia is a method whereby drugs are applied intrathecally as a single dose and epidurally either continuously or intermittently via an epidural catheter. More than 50 years ago, first attempts were made to introduce this method into clinical practice but they found little general acceptance. Only during the last decades has tremendous progress been made in developing new, highly-sophisticated equipment: matching spinal and epidural needles and catheters, epidural needles with a separate conduit for the spinal needle or with an additional hole for the exit of the spinal needle as well as fixation devices for the spinal needle. A specific feature of the method is the only recently recognised epidural volume extension, which allows the use of low-dose drug combinations with sufficient analgetic properties but less cardiovascular compromise and fewer side-effects. This review describes the main and most important developmental steps and offers practical examples for its use in day-case surgery of the lower limb, in the "walking epidural" in obstetrics and in caesarean section. The method has become a valuable new tool in the armamentarium of the anaesthetist and part of daily routine in many clinics.
