In the 1840s, the introduction of ether, a surgical anesthetic, made surgical procedures more common. Initially, general anesthesia was given through a device that covered the nose and mouth of the patient. The concern for aspiration of gastric content was not appreciated, and postoperative pneumonia became a common problem. Trendelenburg (1869) designed the first inflatable cuff, a thin rubber bag that was fitted over the end of a tracheostomy tube. It created a tight seal to prevent aspiration during anesthesia. As an alternate method for tracheostomy, Macewen (1880) suggested passing an oral tube into the trachea to relieve an obstruction. Later, anesthesiologist Franz Kuhn used metal tubes and preferred the oral route over tracheostomy and popularized orotracheal anesthesia.
