Residu anestesi tertua ditemukan pada peralatan bedah Tiongkok kuno

Residu pada instrumen medis abad ke-15 menunjukkan bahwa dokter Tiongkok menggunakan senyawa tanaman beracun untuk meredakan nyeri selama operasi. Penemuan ini memberikan bukti kimia paling awal mengenai penggunaan anestesi di mana pun di dunia.

Gunting bedah dan pinset yang ditemukan dari makam dokter Xia Quan, yang hidup dari tahun 1348 hingga 1411 di provinsi Jiangsu, mengandung jejak akonitin. Peneliti di Northwest University di Xi’an mengidentifikasi senyawa tersebut menggunakan analisis laser. Instrumen-instrumen tersebut pertama kali digali pada tahun 1974, namun studi kimianya baru dilakukan baru-baru ini.
