AbstractThe introduction of anaesthesia on 16 October 1846 brought about tremendous changes in the discipline of surgery. We sought to determine whether the concept of painless surgery was accepted by practitioners and patients, and whether this led to an increase in frequency and variety of surgical operations performed. To study these changes, we analysed surgical records from Massachusetts General Hospital, Boston, Massachusetts (MGH) in the months surrounding the discovery of ether anaesthesia. Surgical records from MGH between 25 February 1846 and 14 March 1847 were examined, and the variables studied included number of operations, type of operations, patient demographics, complications and analgesics used, as well as comments made by surgeons. Immediately following the introduction of anaesthesia, MGH experienced a sizeable increase in the volume of surgical operations. This included a doubling in the percentage of female patients undergoing surgery. Orthopaedic procedures and amputations both increased in frequency, as did the number of surgeons operating. Several records indicated the presence of postoperative wound infection. Operations were still performed without anaesthesia. Following the introduction of ether anaesthesia in 1846, surgical volume increased, and more women underwent surgery. This suggests early acceptance of anaesthesia by patients and the medical profession. In an era prior to the introduction of antiseptic and aseptic techniques it is not surprising that wound infections were observed in several patients. We provide a glimpse of anaesthesia and surgery during the first few months after the first public demonstration of anaesthesia at MGH.
