Fidel Pagés and the first description of epidural anaesthesia (1921)
A Spanish military surgeon published in 1921, in a Spanish journal, the first description of human thoracolumbar epidural anaesthesia — anatomy, technique, a case series and complications — and named it anestesia metamérica for the segmental block it produced. He was killed in a road accident two years later at thirty-seven, an Italian surgeon's version of the technique carried the field through the 1930s without crediting him, and the correction came from Argentina.
Why this wins its question: Ask who invented the epidural and the usual answer is Dogliotti, or no one in particular. The correct answer is documented, dated and uncontested in the current clinical literature, and this object binds it to both a commemorative history in Anesthesia & Analgesia and an independent 2024 British Journal of Anaesthesia review that states the attribution in passing — while declining to assert what that history itself refuses to assert, namely why the credit went missing for eighteen years.
Claims
Every assertion below is bound to registered sources and carries its own confidence. Weight them; do not treat the page as uniformly authoritative.
Pagés published "Anestesia Metamérica" in the Revista Española de Cirugía in 1921; the medical-history literature identifies it as the first description of human thoracolumbar epidural anaesthesia, and the paper set out the anatomy of the epidural space, the technique, a case series and the complications rather than announcing a single case.
The attribution is not a niche historical claim: a 2024 narrative review in the British Journal of Anaesthesia states it in its own voice — "Subarachnoid and epidural anaesthesia were first described by August Bier in 1898 and Fidel Pagés in 1921, respectively."
He coined the name for what the technique does. "Anestesia metamérica" describes the segmental anaesthesia intrinsic to the method — blocking by body segment rather than by everything below a level — which is the property that distinguishes it from the subarachnoid block described by Bier a generation earlier.
He was a military surgeon, not an academic anaesthetist. Born at Huesca in 1886, Pagés served as a surgeon in Spain's armed conflicts including the First World War, later worked as a charity surgeon at Madrid's General Hospital, and was editor-in-chief of the Revista de Sanidad Militar. He died unexpectedly in a motor vehicle accident on 9 July 1923, aged thirty-seven, two years after the paper.
The technique reached the world's operating theatres under another name. The Italian surgeon Achille Dogliotti developed the loss-of-resistance method in the 1930s and initially did not credit Pagés; he acknowledged him in 1939, prompted by the advocacy of the Argentinian surgeon Alberto Gutiérrez. The cited authors write that had it not been for Gutiérrez's essays, Pagés's work might have been forgotten.
Why the omission happened is explicitly left open, and this object leaves it open too. The authors offer several candidate explanations — publication in Spanish-language journals of limited circulation, Pagés's early death before his work could travel, professional bias favouring the German and French medical establishments, or Dogliotti's own ambition — and state plainly that "the intentionality of his omission is not known".
The claim being made here is priority of description, not of every component. Bier had described subarachnoid anaesthesia in 1898, and Dogliotti's loss-of-resistance manoeuvre — the thing most anaesthetists actually learn — is his own contribution of the 1930s. What the sources support is that the human thoracolumbar epidural was described first by Pagés in 1921.
