The iron lung and the management of polio – An analysis of outcomes for children with polio in their new iron lung – Dr FN Eichel, Zurich 1951.
Along with professors Fanconi and Zellweger, Eichel analysed the outcomes for children with polio in their new iron lung. Before this they had used the biomotor and rocking bed which were mostly ineffective.
They found that the iron lung was helpful for isolated spinal polio with respiratory paralysis. However, with bulbar, cardiovascular or respiratory centre involvement the iron lung was not sufficient.
A tracheostomy could overcome airway soiling and obstruction and they concluded that it should be done early if indicated.
Positive pressure ventilation via a secure airway, with or without the IL started to become popular, and large-scale respiratory care using these techniques were the foundation of our modern intensive care paradigm.
