Treatment.—Exposure to the irritating substances which are known to provoke an attack should be avoided.
The nose may be syringed out with a lotion containing boric acid and bicarbonate of soda (five grains of each in four ounces of water), or one containing bicarbonate of soda and salt (five grains of each in four ounces of water), to which has been added two to four drops of carbolic acid. The interior of the nostrils may be anointed with vaseline. Menthol snuff is of great value. A substance called “Pollantin” has a specific action in many cases, but it should be employed only under medical supervision.
Influenza.
Influenza has been introduced into many tropical countries, in which it has spread rapidly and caused in many instances a very heavy mortality. The actual cause of the disease is still a matter of dispute, but there can be no doubt that it is chiefly spread by personal contact.
Symptoms.—What may be called the respiratory type is pretty well known to everyone, but it should not be forgotten that sometimes the main stress of the disease falls either on the alimentary or the nervous system, while there is also a type of what is known as febrile influenza in which the heat-regulating centre is greatly upset. In this latter form the temperature may be intermittent and it is then apt to be mistaken for malaria.
The respiratory type is the most important. Its incubation period is short, one or two days. The onset is sudden and is characterized by shivering, pains in the back and limbs, severe headache and a feeling of malaise. The patient may be giddy and suddenly collapse, his throat is often dry and sore and he has an irritating cough. His temperature rises and runs up to 102° to 104° F. His face becomes flushed, his eyes reddened and his tongue is furred. Constipation is common. Uncomplicated influenza, if promptly attended to, is not a very serious disease, and improvement usually sets in about the third day. The most serious complication of influenza is bronchial pneumonia, and in some forms of the disease the heart is very apt to be affected.
Prophylaxis.—Isolation of cases; free ventilation; treat patients as much as possible in the open air. Nurses and those attending the sick should be careful about contracting infection from the patient’s invisible mouth spray. Indeed in some epidemics the use of face masks has been recommended.
Treatment.—Rest in bed as soon as possible; free purgation at the outset; an early dose of twenty to thirty drops of laudanum (Tinct. opii) is often very beneficial but the drug must be administered with care. Aspirin in ten-grain doses thrice daily frequently relieves the more urgent symptoms. In cases where there is vomiting and collapse with high temperature a dose of fifteen grains of aspirin with half to one ounce of brandy and three drachms of liquor ammon. acetat. may act like a charm. According to our present knowledge, however, it would seem that drugs are of little use in influenza, and that the important thing is to ensure good nursing and to keep up the patient’s strength. Quinine in effervescing form is very useful for convalescent cases.
