CHAPTER V
PREVENTION OF ATTACKS
  In health matters, prevention is nine points of the
  law.
  
  Some patients are obsessed by a peculiar sensation (the "aura") just before a fit. This warning takes many forms, the two most common being a
  "sinking" or feeling of distress in the stomach, and giddiness. The character of the aura is very variable - terror, excitement,
  numbness, tingling, irritability, twitching, a feeling of something passing up from the toes to the head, delusions of sight, smell, taste,
  or hearing (ringing, or buzzing, etc.), palpitation, throbbing in the head, an impulse to run or spin around - any of these may warn a
  victim that a fit is at hand. Some patients "lose themselves" and make odd mistakes in speech.
  The warning is nearly always the same each time with the same patient, and is more common in mild than in severe cases. Rarely, the attack does not go beyond this stage.
  When the patient becomes conscious of the aura he should sit in a large chair, or lie down on the floor, well away from fire or any other danger, and from
  anything that can be capsized. He must never try to go upstairs to bed.   Some one should draw the blind, as light is irritating.
  If the warning lasts some minutes, the patient should carry with him, a bottle of uncoated one-hundredth-grain tabloids of
  Nitroglycerin, replacing the screw cap with a cork, so that they can quickly be extracted. When the [pg 26] warning occurs, one or two should be taken, and the head bent forward. The
  arteries are dilated, the blood-pressure thus lowered, and the attack
  may be averted.
  The use of nitroglycerin is based on the theory that seizures are
  caused by anĉmia due to vasomotor constriction. Success is only
  occasional, but this is so welcome as to justify the habitual use of the
  method.
  If the aura be brief, buy a few "pearls" of Amyl Nitrite, crush
  one in your handkerchief, and sniff the vapour. This has the same affect
  as nitroglycerin, but the action occurs in 15 seconds and only persists 7
  minutes. A headache occasionally follows the use of these drugs, and they
  should not be employed without professional advice.
  When the warning is felt in the hand or foot, a strap should be worn
  round the ankle or wrist, and pulled tight when the aura commences. This
  sometimes aborts a fit, as biting a finger in which the aura commences
  may also do.
  If a victim feels unwell after a meal, he must never eat the next meal
  at the usual time, simply because it is the usual time.
  Should a patient feel unwell between, say, dinner and tea, instead of
  eating his tea he must empty his bowels by an enema, or croton oil (see
  chemist), and his stomach by drinking a pint of warm water in which has
  been stirred a tablespoonful of mustard powder and a teaspoonful of salt.
  After vomiting, drink warm water.
  Never attempt to empty the stomach at the onset of a definite
  aura, for if the seizure occurs, the vomit will probably obstruct the
  trachea, and suffocate the victim.
  After the stomach has been empty ten minutes, the patient should take a double dose of bromides (Chapter XIX) and go to bed. Next morning he will be well, [pg 27] whereas if he eats but a single piece of bread-and-butter he will probably have a fit within five minutes.
  Unfortunately, in 60 per cent of cases, there is no warning at all, while in those cases which do exhibit an aura, the measures mentioned above more often fail than succeed.
