----------+---------+-------+-----------+---------+------------------
In scarlet fever, infection is due to the particles which peel
off from the skin, the patient should be anointed once a day with
carbolic oil, made with 1 part carbolic acid to 50 of olive oil. The
efflorescence (peeling off) occurs first on the skin of neck and
arms, sometimes as early as the fourth day. The anointing should
include the head, the oil being freely applied to the roots of the
hair, and continued for 6 weeks, a warm bath being given weekly
during that time. After 6 weeks, the patient may mix with the other
members of the family; but children should not return to school for 2
weeks longer.
In measles, the same rules are to be observed, with the addition that
the discharges from mouth and nostrils should be received on rags and
destroyed by burning.
In typhoid fever, the poison is chiefly contained in discharges
from the bowels. These may infect the air of the sickroom, the bed,
body-linen, w.c., and drains, and, by soaking into wells, they poison
the drinking-water--a common and dangerous way by which this fever
spreads. The discharges should be disinfected immediately on their
escape from the body as will be directed.
Typhus fever is very infectious, and is apt to attack those who are
much exposed to it for the first time; therefore engage a nurse who
has been previously attacked. The poison is thrown off by the skin
and lungs and readily affects clothing, furniture, and everything in
contact with the air of the room.
Efficient protection from smallpox is proper vaccination, known by
a large mark or scar. Re-vaccination after the fourteenth year is
advisable. Smallpox affects at a greater distance than any other, the
poison escaping chiefly by the skin and mucous membrane.
Diphtheria poisons by the breath and expectoration; and to avoid
contact with these is absolutely necessary. The expectoration should
be received into a vessel containing Condy’s fluid, or on rags that
may be at once burnt. Gargle the throat frequently with a solution of
the same, of the strength of 1 small teaspoonful to 1 qt. water.
Whooping-cough is a disease which is most fatal to children under 2
years of age. The poison comes chiefly from the mucous secretions of
the lungs and air passages, and is readily imparted to the clothes of
those who nurse the patient; the secretions are infectious from the
beginning.
Asiatic cholera rarely visits this country. As in typhoid fever, it
spreads by means of the bowel discharges, and the same precautions
are needed.
In any infectious disease, where the home has no accommodation for
fully carrying out the precautions, the patient should be removed at
once to a fever hospital. No time should be lost in obtaining medical
advice.
One other source of danger may be mentioned here, and that is
the poisonous vapours arising from broken gas mains, which will
cause illness and even death from the carbonic oxide present. As a
precaution against ground air contaminated with illuminating gas
entering houses, open all cellar windows, as well as those on the
ground floor of threatened houses, so as to prevent directly sucking
in the ground air or render it harmless by dilution. The smell of gas
should serve as a warning.
The following advice is addressed to those who have to visit or
attend upon infectious cases. Always have the window open before
entering the patient’s room or ward. Never stand between the patient
and the fire, but always between him and the open window. If possible
change your coat before entering the room. Do not go in for any
unnecessary physical examination. Stay as short a time as possible in
the room. Never, while in the room, swallow any saliva. After leaving
the sickroom, wash the hands with water containing an antiseptic.
Rinse out the mouth with diluted “toilet sanitas” or Condy’s fluid;
also gargle the throat with it, and bathe the eyes, mouth, and
nostrils. Expectorate and blow the nose immediately on leaving the
sickroom. Keep up the general health by good food, exercise, and
temperance. Filter all the air you breathe while in the sickroom or
ward through an antiseptic medium, such as a McKenzie inhaler over
the nose and mouth; carefully soak the sponge in a strong solution of
carbolic acid before entering the sickroom; all the air breathed must
necessarily come through this sponge, and the expired air is emitted,
by a valve action, at another place.
Nurses should keep themselves and their patients as clean as
possible, remembering that the more the infection accumulates, the
more dangerous does it become. Special care should be taken, in
changing sheets and clothing, not to shake or disturb them more than
is absolutely necessary to remove them; as these acts disseminate the
particles of skin which are removed with them, and which convey the
germs of disease, they should be removed carefully, folded together,
and immediately disinfected.
Whatever the nature of a malady, so soon as it is pronounced to be
infectious the same precautions should in all cases be taken. Let
it at once be decided who is to nurse the patient, and make all
arrangements by which nurse and patient may be isolated from the rest
of the household. If possible, 2 rooms communicating should be given
up to them, and over the outer doors of these rooms sheets should be
hung, which must be kept constantly saturated with disinfectants,
either Condy’s fluid or carbolic acid in water. No servant in
communication with the rest of the household must enter the sickroom;
if she does so, she should be isolated like the nurse, and any
message that may require to be given must be spoken through the
sheet. The best plan is to have a regular nurse from one of the many
excellent institutions which provide them; they make the patient more
comfortable, take entire charge of the arrangement of the sickroom,
and know exactly what is required to be done in an emergency, and
for disinfection. At the very commencement all curtains should be
taken down, and at once sent out of the house to be disinfected by
properly qualified persons; the same course should be pursued with
the carpets (woollen articles hold infection beyond any others), and
then the floors can be kept sprinkled with disinfectants, besides
having a broom steeped in them passed over every morning. Linen used
in the sickroom should always be put into water with either carbolic
or Condy, before leaving the room; but, even with this precaution,
it is far better to send it to be disinfected than to allow it to go
to a laundry. The windows should be open, top and bottom, but more
especially at the top, during the entire day, and if possible at
night also; a thorough draught through the room is most desirable,
if the patient can be kept out of the direct line of it. As much
as possible, all cups, basins, jugs, and glasses should be kept
upstairs; but those that must occasionally be sent down should be
carefully washed in Condy and water, and at once placed outside
the door, and again passed through disinfectant on their arrival
downstairs. The clothes that may have been worn for the day or two
before the disease absolutely declared itself should be sent for
disinfection, but those which have only been in casual contact may be
disinfected at home. A small room should be chosen for the purpose,
and the dresses, petticoats, shawls, or other articles hung up, so
as to be fully exposed. The doors, windows, and all other apertures
must be kept closed, and the disinfection may be effected either by
chlorine, which is formed by pouring hydrochloric acid on chlorate of
potash, or else by burning sulphur. In either case the quantity must
be sufficient to render the atmosphere of the room unbearable to a
human being, or otherwise the disease germs will not be destroyed.
The bedding and blankets must be sent for proper disinfection at
the close of the illness. Nothing should be kept in the room except
for use. Clothes in a wardrobe under such circumstances have been
known to spread infection 10 years after. Handkerchiefs should be
replaced by rags, burnt when used. Letters from the patient should
be backed, or written on postcards dipped in carbolic; they are
capable of spreading disease otherwise. A thing in which people are
often lamentably careless is in allowing books that have been used by
the patient to be afterwards used by others. It cannot be too often
impressed on the minds of those who have to do with illness, that
every book, paper or magazine used by an infectious patient must be
burnt without leaving the sickroom. Infection is very often spread by
allowing books from a circulating library to be returned to it after
use by a person suffering from an infectious disorder.
Infection ceases in the individual as soon as the skin has thoroughly
peeled--a process which takes a longer or shorter time in different
individuals. The danger after this lies in the clothes, furniture,
and rooms, and if these are at once thoroughly disinfected all danger
is absolutely at an end. It is impossible to reprobate too strongly
the conduct of those who wish and endeavour to shirk the expense and
trouble of proper disinfection. It would be well if in such cases
doctors would always avail themselves of their power to report the
existence of a case of infectious disease to the sanitary officer
of the district, when official pressure would at once be brought to
bear, and all that is necessary be effected under compulsion.
The cured patient on the day of leaving home should go into a fresh
room to dress, and put on things either new or disinfected, not
returning to the sickroom. Brushes and sponges, as coming most in
contact with hair and skin, are best destroyed. While a patient is in
the infectious stage it is best that no letters should be written;
but if, as is sometimes the case, some communication in writing must
be made, danger is obviated by holding the paper and envelope in the
fumes of chlorine.
A few words would not be amiss respecting those in the house who do
not enter the sickroom. However great the precautions taken, the
air of a house in which there is a case of infectious disease can
never be absolutely safe, and it is far better to err on the side of
caution than the reverse. Visitors should not be allowed to enter the
house, and it is far better and more honest for the servants to state
clearly at the door what disease is in the house. Special attention
should be paid to the health of each member of the household. Any
slight disorder is liable to predispose to infection.
There is a great variety of good disinfectants, and as many different
ways of using them. A good plan, both effective and economical, is
as follows:--Freely use moistened chloride of lime all through the
house, and even in the sickroom, if the fumes are not found to be
irritating; secondly, place in various parts of the room 5 or 6
soup-plates, or other flat vessels, containing Condy’s fluid; or
hang about in the room as many perforated boxes filled with solid
iodine; thirdly, keep the windows opened freely but the doors as
seldom as possible; guard it both inside and outside with a large
sheet, hung up to at least the height of the door, and at about 1 ft.
distant from it, and kept constantly well moistened with a solution
of carbolic acid (strength, about 1 of the acid to 40 of water); and,
most important of all, receive as soon as possible all discharges,
excreta, soiled linen, and all such matters, in vessels containing
a strong solution of Condy’s fluid, chloralum, or carbolic acid.
Many infectious diseases have (in addition to their common property
of infecting the air through the effete products of respiration
from the lungs and skin) some special channel of transmission. In
cholera, typhoid (enteric) fever, and, in a less degree, typhus and
relapsing fevers, it is principally by the excreta from the bowels
and kidneys. These should be received at the very moment of their
issue from the body into vessels fully charged with disinfectants. In
diphtheria, it is by the throat. In erysipelas, hospital gangrene,
and puerperal fever, by discharges peculiar to each. In smallpox, by
pustular exudation from the skin. In scarlet fever, measles, &c., by
desquamation (peeling off of the skin), rendered harmless by slightly
moistening the surface of the body once or twice a day with ordinary
olive oil or camphorated oil, or a weak solution of glycerine and
carbolic acid. Never mix disinfectants; for instance, Condy’s fluid
and carbolic acid act in precisely opposite ways, and might decompose
each other.
The nurse must not neglect proper precautions for her own safety. She
should use disinfectants freely about her own person, be sure that
she has a sufficient quantity of undisturbed rest and regular meals,
and avoid coming into unnecessary close contact with the patient.
She should at once give up the occupation if she feel her general
health at all injured. She must also be careful not to undertake a
non-infectious case after being in attendance upon an infectious one
for a considerable time; and until she has put herself through a
complete process of disinfection, and done the same with all clothes
worn at the time which she has not discarded altogether. Nothing must
induce her to go near a confinement for several (at least 3) months.
Disinfection.--The most useful agents for the destruction of
spore-containing infectious materials are:--
(1) Fire: Complete destruction by burning.
(2) Steam under pressure: 230°F. for 10 minutes.
(3) Boiling in water for 1 hour. This temperature does not destroy
the spores of _Bacillus subtilis_ in the time mentioned, but is
effective for the destruction of the spores of the anthrax bacillus,
and of all known pathogenic organisms.
(4) Chloride of lime: a solution of 4 in 100 containing at least 25
per cent. of available chlorine.
(5) Mercuric chloride: a solution of 1 in 500 containing at least 3
per cent. of available chlorine.
For the destruction of infectious material which owes its infecting
power to the presence of micro-organisms not containing spores:--
(1) Fire: Complete destruction by burning.
(2) Boiling water ½ an hour.
(3) Dry heat: 230°F. for 2 hours.
(4) Chloride of lime: 1 to 4 in 100 solution, containing at least 25
per cent. available chlorine.
(5) Solution of chlorinated soda: 5 to 20 in 100 solution, containing
at least 3 per cent. available chlorine.
(6) Mercuric chloride: a solution of 1 in 1000 to 1 in 4000.
(7) Sulphur dioxide: exposure for 12 hours to an atmosphere
containing at least 4 volumes per cent. of this gas, preferably in
presence of moisture. This will require the combustion of 3-4 lb.
sulphur for every 1000 cub. ft. of air space.
(8) Carbolic acid: 2 to 5 in 100 solution.
(9) Sulphate of copper: 2 to 5 in 100 solution.
(10) Chloride of zinc: 4 to 10 in 100 solution.
Following are recommendations with reference to the practical
application of these agents:--
For Excreta.
(_a_) In the sickroom:
For spore containing material:
(1) Chloride of lime in solution, 4 in 100.
(2) Mercuric chloride in solution, 1 in 500; addition of an equal
quantity of potassium permanganate as a deodorant, and to give colour
to the solution, is to be recommended.
In the absence of spores:
(3) Carbolic acid in solution, 5 in 100.
(4) Sulphate of copper in solution, 5 in 100.
(5) Chloride of zinc in solution, 10 in 100.
(_b_) In privy vaults:
Mercuric chloride in solution, 1 in 500. A concentrated solution
containing 4 oz. mercuric chloride and 1 lb. cupric sulphate to 1
gal. water is recommended as a standard solution; 8 oz. this solution
to 1 gal. water will give a diluted solution for the disinfection of
excreta, containing about 1 in 500 of mercuric chloride and 1 in 125
of cupric sulphate.
(_c_) For the disinfection and deodorisation of the surface of masses
of organic material in privy vaults, &c.:
Chloride of lime in powder, diluted with plaster of Paris, or with
clean, well-dried sand, in the proportion of 1 part to 9.
For Clothing, Bedding, &c.
(_a_) Soiled underclothing, bed linen, &c.:
(1) Destruction by fire, if of little value.
(2) Boiling at least ½ hour.
(3) Immersion in a solution of mercuric chloride of the strength of 1
in 2000 for 4 hours. The blue solution containing sulphate of copper,
diluted by adding 2 oz. concentrated solution to 1 gal. water, may be
used for this purpose.
(4) Immersion in a 2 per cent. solution of carbolic acid for 4 hours.
(_b_) Outer garments of wool or silk, and similar articles, which
would be injured by immersion in boiling water or in a disinfecting
solution:
(1) Exposure to dry heat at a temperature of 230° F. for 2 hours.
(2) Fumigation with sulphurous acid gas for at least 12 hours,
the clothing being freely exposed, and the gas present in the
disinfection chamber in the proportion of 4 volumes per cent.
(_c_) Mattresses and blankets soiled by the discharges of the sick:
(1) Destruction by fire.
(2) Exposure to superheated steam--25 lb. pressure--for 1 hour.
Mattresses to have the cover removed or freely opened.
(3) Immersion in boiling water for 1 hour.
(4) Immersion in blue solution (mercuric chloride and sulphate of
copper) 2 fl. oz. to 1 gal. of water.
Fire.--Materials used in wiping away discharges may be burned in the
open fireplace of the sickroom. In general, this method is to be
recommended for all substances which have been exposed to infection,
which cannot be treated with boiling water, and, could it be carried
out in all cases, would make disinfection a very simple matter. If
there is no fire in the room, such substances may be wrapped in a
sheet soaked with solution, carbolic acid, and in this condition
conveyed to a fire elsewhere.
Boiling Water.--Boiling in water for ½ hour will destroy the vitality
of all known disease germs. This is therefore the best means for all
articles which can be thus treated, such as body-clothing of the
patient, bed-clothes, towels, &c. All utensils used in the room in
feeding the patient should likewise be treated with boiling water
before being removed from the room. Food itself, not consumed by the
patient, should not be used by others, as it is liable to become
infected in the sickroom. If there are no facilities for treating
articles with boiling water in the sickroom, they may with safety be
removed to another part of the house for this treatment if they are
carefully enveloped in a towel or sheet, as the case may require,
which has been thoroughly soaked with carbolic acid solution. Thus
enveloped, they should be put in the water, and boiled for the
required time.
Chloride of Lime.--To be effective as a disinfectant this must be of
the best quality, and in purchasing it, only that should be accepted
which is enclosed in glass bottles, as, when packed in paper or
wooden boxes, it is liable to have so deteriorated as to be worthless
for disinfecting purposes. Dissolved in water, in the proportion of
4 oz. to 1 gal., it forms a standard solution recommended to be used
in the disinfection of discharges in contagious diseases, especially
in typhoid fever and cholera; 1 pint should be well mixed with each
discharge; after 10 minutes, disinfection is completed, and the
contents of the vessel may be then safely thrown into the water
closet. The expectorated matter of those sick with consumption should
be discharged into a cup half filled with this or carbolic acid
solution.
Solution of Chlorinated Soda.--To be effective, this solution must
contain at least 3 per cent. of available chlorine, and care should
be exercised to obtain such a quality. This is sometimes spoken of
as Labarraque’s solution; but, as this latter is too weak to act as
a disinfectant, the name is liable to mislead. A standard solution
is made by adding 5 parts water to 1 of the solution of chlorinated
soda. The cost of this solution is about 5_d._ a gallon. When thus
diluted it may be used for all the purposes for which chloride of
lime was recommended, and is of a somewhat more agreeable odour,
though more expensive. It should be used to cleanse portions of the
body soiled with discharges of those sick with infectious diseases,
or the hands of attendants similarly soiled.
Bichloride of Mercury (corrosive sublimate) is recommended to be
used only in the disinfection of privy vaults which contain so
much material, believed to be infected with the germs of typhoid
fever or cholera, that the disinfection by chloride of lime would
be impracticable. In using this, it should be dissolved in the
proportion of 1 oz. bichloride of mercury to 1 gal. water; this
quantity will disinfect 4 gal. infected excremental matter.
For Clothing after Recovery or Death.
The clothing of the patient should be treated in the manner already
described as necessary during the sickness. Whatever can be boiled
in water should be thus disinfected; articles which cannot be
boiled should, if circumstances will permit, be burned; all other
articles should be left in the room to be subjected to the fumigation
hereafter to be described, and until thus treated, the room and its
contents should be closed with lock and key, to prevent any one from
entering. If it is desired to burn any articles, and facilities for
it do not exist in the house, the authorities should be notified, and
an officer will call and remove the articles for destruction.
Permanganate of potash (commonly known as Condy’s fluid), Burnett’s
fluid, and chloride of lime, can all be mixed with water, and used
for clothing if care is taken. Carbolic soap is excellent for
scrubbing. Sulphate of zinc and common salt, dissolved together in
water in the proportion of 4 oz. sulphate and 2 oz. salt to 1 gal.
will do for clothing, bed-linen, &c.
Armfield & Son, 15 Lower Belgrave Street, London, W., and Victoria
Bridge Road, S.W., disinfect and clean articles after fever, &c., by
means of special apparatus.
For Furniture and Articles of Wood, Leather, and Porcelain.
Washing several times repeated with:
(1) Solution of mercuric chloride 1 in 1000. The blue solution, 4 oz.
to 1 gal. water may be used.
(2) Solution of chloride of lime, 1 per cent.
(3) Solution of carbolic acid, 2 per cent.
For articles of metal use No. 3.
For the Person.
The hands and general surface of the body of attendants of the sick,
and of convalescents at the time of their discharge from hospital:--
(1) Solution of chlorinated soda diluted with 9 parts of water (1 in
10).
(2) Carbolic acid, 2 per cent. solution.
(3) Mercuric chloride, 1 in 1000; recommended only for the hands, or
for washing away infectious material from a limited area, not as a
bath for the entire surface of the body.
For Body of the Patient after Recovery.
When the patient has recovered, he should be first sponged over with
the solution of chlorinated soda, diluted in the proportion of 1
part to 20 of water; and, indeed, during the course of the illness
occasional sponging of the body with this very dilute solution
under the direction of the attending physician, will be of value in
preventing the escape from the surface of the body of infectious
material. When, after recovery, the body has been thus sponged, not
omitting the head and hair, a thorough washing of the body with soap
and warm water should follow, and the patient dressed in clothes
which have not been exposed to infection. This should take place in
another room than the one occupied during the illness.
For the Dead.
Envelope the body in a sheet thoroughly saturated with
(1) Chloride of lime in solution, 4 per cent.
(2) Mercuric chloride in solution, 1 in 500.
(3) Carbolic acid in solution, 5 per cent.
The body should be thoroughly sponged with either (1) or (3), and
then wrapped completely in a sheet saturated with one of these
solutions, and enclosed in a coffin, which is to be closed, and
the interment must take place within 24 hours, and be strictly
private. If the interment is to take place at a distance requiring
transportation by any other means than a hearse, the coffin must be
of metal, or metal-lined, and hermetically sealed.
