The aspirator sucks up liquid and draws out a saline solution. In this case, the device is a hollow needle inserted through the skin of the patient and pulled into a hollow tube. The tube is connected to a vacuum aspirator.
The vacuum aspirator sucks up fluid and draws out a saline solution. At the most basic level, the anesthesiologist controlled the patient's respiration and blood pressure in order to determine how to administer anesthetic solutions. The ipratropium bromide determined the dose of the anesthetic and how long until the patient could be placed on the ventilator and awake again. The patient then was treated according to the anesthetic dose. Anesthesia had advanced dramatically with the advent of chemical and electrical anesthesia in the early years of the 20th century. Ipratropium bromide respects, chemical anesthetics and electrical anesthetics were not yet in the same realm as electric current.
The first electroshock drugs were available in 1971, and the first surgical anesthetic drug was introduced in the 1970s. The anesthetic agent used to sedate patients was initially a mixture of lidocaine and chloral hydrate, but the mixture began to be changed to a single agent over the years in an attempt to reduce its toxicity. The introduction of the first drug in 1977 was a pivotal moment in anesthesia history. This drug was the first, and so far only, direct-acting anesthetic agent to be used in the surgical field, and it was soon replaced by a much more potent agent called hydroxyzine.
