Convulsions, which are both tonic and clonic in character, occur in about 99.5 per cent. of all eclamptic cases and are very distressing to watch. They are sometimes preceded by an aura, but often are so unheralded that they may even occur while the patient is asleep. They ordinarily begin with a twitching of the eyelids; the eyes are wide open and staring and the pupils are first contracted and then dilated. The twitching extends to the muscles about the nose and mouth, then to the neck and arms, and so on until the entire body is convulsive. The patient’s face is usually cyanotic and badly distorted, the mouth being drawn to one side; she clenches her fists, rolls her head from side to side and tosses violently about the bed. She is totally unconscious and insensible to light, and during the seizure may not breathe beyond giving one or two struggling gasps. Her head is frequently bent backward, her neck forming a continuous curve with her stiffened, arched back. Another distressing feature is the protruding tongue and the frothy saliva, which is blood stained if the patient is not prevented from biting her tongue by the introduction of some sort of a mouth gag between her teeth. Such is the typical eclamptic convulsion. The attacks vary greatly in their intensity and duration. There may be only a few twitches, lasting ten or fifteen seconds or violent convulsions lasting as long as two minutes, their number and severity increasing with the seriousness of the patient’s condition. In mild cases there may be but one or two convulsions, particularly if the onset is either late in labor or postpartum. But as a rule, there are several convulsions; ten, twenty or thirty, and sometimes, though rarely, as many as a hundred. The patient always goes into a coma after a convulsion and this also varies in length and profundity, her condition during the intervals being very suggestive of the probable outcome of the disease. If the attacks recur frequently, as they usually do in extreme cases, the patient is likely to remain unconscious during the entire interval; but she will usually awaken between attacks that are far apart, and this is regarded as a hopeful sign. The respirations are labored and noisy as a rule, and the pulse full and bounding, in which case the outlook is good. The temperature is often normal, but may go as high as 104° F. or 105° F., dropping rapidly as the attacks subside. But a weak, rapid pulse together with a high temperature, and above all, a persistently high blood pressure, no matter what the other symptoms may be, are always unfavorable.
