[Analysis of the anesthesiology doctoral theses in Cadiz during the Six-Year Revolution].

Manuel Ruiz Zorrilla, after the 1868 Revolution, made possible in Spain the decentralization of doctorate's studies, which traditionally were done in Madrid. It was because of that fact that the Doctor degree could be obtained at the Faculty of Medicine in Cadiz during the Sexenio Revolucionario. The intention of this work is to analyse the anaesthesiologist doctorate thesis defended at the Faculty of Medicine in Cadiz during that period. We give unpublished news about the evolution of the obstetrics anaesthesia in Spain and different opinions about the use of anaesthetics in labours at that time.
