Besides the general systemic conditions in which sudden death may occur without anticipation, there are certain specific diseases of which unexpected death is sometimes a feature. For the clergyman to know the condition in which the sudden fatal termination is liable to occur is to be forearmed against the possibility of death without the Sacraments, or their enforced administration in haste, when the recipient is in a very unsatisfactory condition of mind and body. It has been said that if a normally healthy individual reaches the age of twenty-five he is reasonably sure to live to a good old age, provided he does not meet with an accident or catch typhoid fever or pneumonia. Pneumonia is an extremely important affection as regards its prognosis. From 15 to 20 per centum of sufferers from the disease die; that is to say, about one in six of those attacked by the disease will not recover. It is a little more fatal in women than in men. It is especially serious for the very young and the old. Healthy adults in middle life very rarely die from the disease. The prognosis of any individual case, it has been well said, depends on what the patient takes with him into the pneumonia. Serious affections of important organs nearly always cause fatal complications. If the heart is affected before the pneumonia is acquired, then the prognosis is very unfavourable, and a fatal termination is almost inevitable. If the kidneys are seriously diseased beforehand, death is almost the rule. Pneumonia developing during the course of pregnancy is fatal in more than one-half of the cases. At one time it was suggested that premature delivery of pregnant {151} pneumonia patients might save at least the mother's life. Experience in Germany, however, has shown that, far from making the prognosis more favourable, the induction of premature labour makes the outlook a little worse for the patient. Previous affections of the lungs, emphysema, or tuberculosis, are prone to make the prognosis of pneumonia much more unfavourable than under ordinary circumstances. Deteriorated conditions of the blood, anaemia, chlorosis--such as occurs so commonly in young women--is prone to make the outlook in pneumonia more serious. Pneumonia of the upper lobes of the lungs is more apt to be followed by complications, and is therefore more serious than pneumonia of the lower lobes. Secondary pneumonia--that is, inflammation of the lungs which develops as a complication of some other disease--is much more unfavourable than primary pneumonia which develops in the midst of health. The amount of lung involved is of course a serious factor in the prognosis. If the whole of one lung is consolidated, or if considerable portions of both lungs are thus affected, the prognosis becomes extremely unfavourable.
