The history of subcutaneous oxygen therapy.

Soon after the discovery of oxygen, experiments began on the use of oxygen for therapeutic purposes, including subcutaneous administration of oxygen, on humans and animals. The history of subcutaneous oxygen therapy (SQOT) is examined in the context of the growing understanding of the use and methods of oxygen administration. Little was written about this therapy until the 19th century, despite an advocacy for its use in some circles. There was resurgence in the use of SQOT in the early 20th century. Investigators in the field of anesthesia, including such notable figures as Paul M. Wood, Ralph M. Waters, and John Henry Evans, contributed to the growth in popularity of the therapy and to the literature on the subject. Although SQOT has been supplanted by other means of administration, it may have a role in management of some inflammatory or pain conditions.

Seeing an anesthetic revolution: ocular anesthesia in history.

Each surgical procedure places unique demands on the anesthesiologist to create surgical anesthesia with minimal physiologic trespass on the patient as well as the surgical repair. In surgery of the eye, the quest for an anesthetic that does not harm the eye or the patient can be a challenge. The removal of cataracts is one of the most frequently performed operations in the United States, and the majority of patients requiring the procedure are elderly and often have other significant medical conditions.

Inhaled anesthetics: an historical overview.

Inhalational agents have played a pivotal role in anesthesia history. The first publicly demonstrated anesthetic of the modern era, diethyl ether, was an inhalational anesthetic. The attributes of a good agent, ability to rapidly induce anesthesia, with limited side effects has led research efforts for over a hundred and fifty years. The explosion hazard was largely conquered with the development of the halogenated agents in the 1950s. Rapid emergence, with limited nausea and vomiting continue to drive discovery efforts, yet the 'modern' agents continue to improve upon those in the past. The future holds promise, but perhaps the most interesting contrast over time is the ability to rapidly introduce new agents into practice. From James Young Simpson's dinner table one evening to the operating suite the next day, modern agents take decades from first synthesis to clinical introduction.

Developing a specialty: J.S. Lundy's three major contributions to anesthesiology.

John S. Lundy was able to accomplish three major goals during the early years of his stewardship of the section on anesthesia of the Mayo Clinic. In 1925, Lundy established the first anatomy lab at the Mayo Clinic. He believed that the lab would serve as a useful tool for teaching residents as well as research into regional anesthetic techniques. Second, Lundy desired to advance the science of anesthesiology. Lundy developed the concept of balanced anesthesia, pioneered the introduction of barbiturates to the practice of anesthesia, developed anesthesia section services for the use of ventilators, ventilator vests, oxygen tents, and nasal oxygen supplementation. Lastly, in 1935, he established the nation's first blood bank. Lundy and Ralph Tovell had the opportunity to do pioneering work in transfusion medicine, which led to an improvement in the quality of service, and patient safety. These three major accomplishments provided Lundy with abundant scientific material to present to the American Medical Association (AMA) in Chicago. These trips to Chicago allowed him to gain the ear of Olin West, Morris Fishbien, and James E. Pallin. Lundy was able to successfully lobby in 1939 for the creation of a section of anesthesia within the AMA. In 1940, Lundy's dream came true with the recognition of anesthesia as a specialty by the AMA.

Myocardial stunning during abdominal hysterectomy in a healthy woman.

We report a case of myocardial stunning in a healthy patient. During gynecologic surgery, two brief episodes of asystole occurred. Following resuscitation there was a short period of severe hypertension and tachycardia. Electrocardiographic changes and elevations in troponin T and creatine-kinase-MB were observed. Angiography revealed normal coronary arteries and multiple areas of hypokinesis. Within 2 weeks, all abnormal values had returned to normal and the patient underwent an uneventful surgery.

Gaston Labat, John Lundy, Emery Rovenstine, and the Mayo Clinic: the spread of regional anesthesia in America between the World Wars.

The spread of regional anesthesia in America was greatly facilitated by the work of Gaston Labat. Recruited to work at the Mayo Clinic, Dr. Labat there published his seminal textbook, Regional Anesthesia, in which he laid out his techniques to the next generation of physician specialists, notably John Lundy, Ralph Waters, and Emery Rovenstine. It was Rovenstine who was responsible for creating the specialty of anesthesiology in the 1920s and 1930s. John Lundy continued Labat's work at the Mayo Clinic when Labat left for Bellevue Hospital in New York. There, while teaching, Labat further developed and refined his techniques for delivering regional anesthesia.
