19th century pioneering of intensive therapy in North America. Part 3: the Fell-O'Dwyer apparatus and William P Northrup.
Two previous articles in this series have described the reintroduction of forced respiration for ventilatory difficulties, particularly in opiate poisoning (by George Fell), and successful use of intralaryngeal tubes designed for treating airway obstruction in diphtheritic acute laryngitis (by Joseph O'Dwyer). In 1891, O'Dwyer extended the applications of Fell's system, introducing a longer orolaryngeal tube, replacing Fell's methods of inflating the lungs, which had been with a somewhat unsatisfactory facemask or through a tracheotomy tube. The combined system became known as the "Fell-O'Dwyer apparatus". Use of the apparatus widened, to include treating apnoea from intracranial disasters (by William P Northrup, especially) and, on the initiative of Rudolph Matas, in delivering anaesthesia and maintaining lung inflation to enable intrathoracic surgery (by FW Parham). Although the apparatus was used beyond New York (eg, in New Orleans by J D Bloom, especially for neonatal apnoea), it is difficult to find other than nonspecific references. Matas and Bloom improved O'Dwyer's original system, but after the clinical success of Charles Elsberg's continuous insufflation anaesthesia for thoracic surgery, 1909, American anaesthetists came to prefer that.
