Pneumonia Mortality/ 100.000 patients

Gilbert K, Fine MJ; Sem Respir INF. 1994; 9:140-52


Pneumonia Guidelines 1943 1.  A glass of water every hour. 2.  Open air- on porch or with bedroom windows open. (If the patient is old and weak delete or modify this order. 3.  To take a patient with active pneumonia to the x-ray room is not only a confession of complete incompetence, it may almost be said to be malpractice. 4.  Apply flannel pneumonia jacket and chest compress if grateful to patient. 5.  The bowels should be opened. 6.  Alcoholics with pneumonia may become noisy and if they do, should be given alcoholic drinks.

Although the management of critically ill patients has improved by far and there are no resistance problems with regard to S. pneumoniae, mortality of IPD remains tremendous. 1. 2. 3.

First new antibiotic in 30 years discovered in major breakthrough Teixobactin has been found to treat many common bacterial infections such as tuberculosis, septicaemia and C. diff, and could be available within five years. Northeastern University in Boston, Massachusetts, have discovered a way of using an electronic chip to grow the microbes in the soil and then isolate their antibiotic chemical compounds.
