- The first organization of physician anesthesiologists in the United States was the Long Island Society of Anesthetists, established in 1905.
Anesthesia in Saudi Arabia
- Due to a shortage of anesthesiologists and the increasing demand for surgical services in Saudi Arabia, Dr. Mohamed Ishaq Al Khawashki proposed the creation of technical institutes to train anesthesia technicians to work under the supervision of consultant physicians. This was known as the "technician's era."
- Professor Mohammed Abdullah Seraj is considered the "father of anesthesia" in Saudi Arabia. He established the first anesthesiology department at King Abdul-Aziz University Hospital, King Saud University, which had only two operating theaters and 70 beds.
Roles and Responsibilities
- Anesthesiologists are physicians specifically trained in anesthesia, completing a six-year medical school program followed by four years of anesthesiology residency training.
