Argumosa introduced ether-induced anesthesia to Spain on 13 January 1847, only three months after
John Collins Warren and
William T. G. Morton first demonstrated its use in
Boston, and only months after it was tested by
François Magendie at the Paris Academy of Medicine. He attached a cow's bladder containing one ounce of ether to the patient's mouth with a metal
cannula, which they would breathe. Afterwards, he also used
chloroform to anesthetize the patient. Argumosa also developed new surgical techniques, and improved upon existing surgical practices. He changed the position of the patient during surgery, operating on them when they were lying down instead of the seated position that was generally used, so that they could better withstand the pain of the procedure. He developed new techniques to
amputate the thigh and the
anal fistula, which he described in his
monographs. He invented the "basted suture," which he used to treat
aneurysms. He also was among the first to practice
phlebotomy, suturing the tear in a vein. He developed an intestinal suture that could be naturally expelled from the channel through which it was placed, which did not necessitate the
laparotomic incision that was previously required for suture removal. Some of his innovations were in the field of general medicine: he was an early practitioner of
asepsis, taking exceptional care to clean his hands, instruments, and the operating room. He isolated patients while they were undergoing surgery, instead of operating in a room with other patients. He was also an innovator in the field of
otorhinolaryngology. He developed the
blepharoplasty technique to remove tumors in the lower eyelid, cancers of the cheekbone, and to treat the loss of the outer part of the eyelids. He developed the
cheiloplasty technique to treat lip cancers. He improved the
rhinoplasty technique. He also developed the syringotome, a special type of
scalpel. Among his developments in
urology were his technique to puncture the
bladder (cytotomy), various methods of removing
urinary calculi, external and internal
urethrotomies, the subcutaneous
ligation of
varicocele veins using the
fisherman's knot, and genital operations. Argumosa also contributed to the field of
arthrology, although it was his students who developed upon his work. He founded a school that was continued by two of his primary students: Juan Creus, a forefather of
taurotraumatology (
bullfighting injuries), and Melchor Sánchez de Toca. In 1854, he retired to Torrelavega to write
Resumen de Cirugía (
Summary of Surgery), which was published in 1856. The work described the general knowledge of surgery at that time and all of his innovations, and was accompanied by illustrations and descriptions of the surgical instruments that he had created for his procedures. == Sor Patrocinio's stigmata ==
