The reservoir, tubing, and douche pan or Kelly pad, are required. An ordinary fountain syringe with a vaginal hard rubber tip will answer, but a glass tube with side perforations makes the best douche.
The patient must be on her back, and if the perforations are not on the side of the nozzle care must be taken that the stream be not directed into the cervix. The noz zle should preferably lie behind the cervix.
The solutions are almost always hot, always if they are to be continued for any length of time. The heat lessens uterine excitability and contractility and hence relieves pain, and many times will abort what would otherwise terminate in a suppurative inflammation. The temperature should be about 110° F., but may be increased, if desirable, to as high as 125° or 130°. This is as hot as can be borne. Various solutions are used: antiseptics, astringents and physiologic saline, the latter most frequently and most advantageously for prolonged irrigation.
