History of Dental Anesthesia - History Of Dentistry And Medicine
During the first half of the 19th century, nitrous oxide, also known as laughing gas, was widely used for frolicking parties and public demonstrations, where audience members pranced around on stage while under the influence of NO. In 1844, Horace Wells, a Connecticut dentist, observed such a public demonstration by Gardner Coulton.
Four hundred and ten dental anaesthetics administered at the Royal Dental Hospital, during August 1961 were studied by recording: (1) the ps mixtures delivered; (2) the pressures developed within the nosepiece; (3) the indirect systolic blood pres-
In 1844, American dentist Horace Wells demonstrated the use of nitrous oxide, also known as laughing gas, for painless tooth extraction. This marked the first successful use of inhalation anesthesia in dentistry and paved the way for further exploration of anesthesia techniques.

2012年2月1日 · Nitrous oxide, by contrast, as a weak anaesthetic gas had to be given at 100% in order to induce surgical levels of anaesthesia, therefore depriving the patient of oxygen during the time of administration.
Dentistry and dentists played an important role in the evolution of anaesthesia. Of all surgical procedures in the early 19th century, tooth extraction was by far the most common, and a regular reminder that surgery and pain were inseparable partners.

2017年3月21日 · Early anesthetic apparatus lacked a means to deliver precisely known flows (and therefore concentrations) of oxygen and nitrous oxide in the gases presented to the patient . In 1902, dentist Charles Teter developed a gas machine that delivered a variable mixture of oxygen and nitrous oxide, each controlled by separate but coarse valves.
Connell 1936 Model - Wood Library-Museum of Anesthesiology
Dr. Karl Connell (1878-1941) introduced a line of closed circuit, multiple-gas anesthesia machines in the 1930s. These were among the first to have a built-in carbon dioxide absorber. This series of machines also had ball-bearing gauges, called flow meters, to accurately display the rate of gases flowing to the patient.
