I never can forget my first case of _childbed fever_. It is only fourteen years ago, and then there was as yet no one who could give a scientifically truthful interpretation of the disease. My patient was a young mother, who was being rapidly consumed by a fever, but beyond that science had not unlocked the causes lurking in the organism, which had doomed the young woman, on the threshold of motherhood, to a premature grave. Thousands of lives were yearly destroyed by _puerperal fever_. Volumes of literature had been written on the subject, but as yet no one had deciphered its origin. Now the whole scene has shifted; we know that the fever is essentially a blood poison, a septic infection of the patient, precisely similar to a wound infection anywhere else on the body. The act of parturition causes wounds or abrasions; these, then, place the woman in imminent danger of infection of every sort, and it is this infection which it is now possible to avoid. There is the greatest precaution necessary on her part and on the part of her attendants, that she be not contaminated by suspicious-looking finger nails, or dirty hands, or soiled linen, or unhealthy and unclean surroundings. The German Government has a compulsory law for a system of antiseptic precautions, which is incumbent upon all who attend lying-in women. The importance of a rule to guide midwives and others in carrying out strictly antiseptic measures was recognized in that country some ten years ago, and the statistics show a remarkable diminution of diseases peculiar to the childbed period. The sources of these infectious micro-organisms are very different. They may be derived from the body of another person, sick or having died from an infectious disease, from suppurating wounds and even from the secretions of healthy lying-in patients. The patient or person herself may have improperly bathed or neglected cleanliness and ablutions, but the greatest danger arises from the neglected and unclean hands and sleeves of the midwives and physicians, and from the instruments usually employed under these circumstances, like forceps, catheters, or the nozzle of a syringe. The law above referred to requires all these instruments to be thoroughly scalded, washed, and brushed every time they have been used, and by such a complete system of disinfection, the chances of infection are reduced to the minimum. I hope some day our legislators will be wise enough to give us similar laws. CHAPTER V. UNCLEANLINESS AS A CAUSE OF DISEASES IN WOMEN.
