Treatment (Pleurisy)
12:46 PM
Pleurisy
With tuberculous
pleurisy this is a long-term matter. In the absence of any reliable specific
remedy, the indications are to support the patient by every means at
our disposal while his own recuperative powers and specific resistance develop.
Rest is the " sheet anchor "—general bodily rest during the febrile phase and stilling of the lung
and pleural movement until absorption has taken place. Strict rest can be a
most valuable measure if the temperature is obstinate in settling, and it is
essential in total effusion. Patients with large effusions are best nursed
propped up and must be very well supported with pillows. Just as too rapid decompression
of the thorax in these cases can lead to fatal consequences, so can sudden redistribution
within the thorax of a large effusion. Fidgeting and restlessness can initiate
such a redistribution. This state of affairs sometimes arises very critically,
the aspect of the patient changing in a moment from one of relative comfort and
calm to one of alarm, apprehension and respiratory embarrassment. He becomes
collapsed, cold and clammy, with a rapid pulse and shallow respiration, and it
is very difficult to rescue him. Oxygen and restoratives should be used at once
and aspiration should be carried out. (See also under "
Complications " and " Management of the fluid ".)
Sampling the fluid (Pleurisy)
12:44 PM
Pleurisy
When fluid is present
in amounts sufficient to give rise to physical signs, it is always wise to take
a sample ; this is done to confirm the presence of fluid in a doubtful case and
to proceed from the recognition of its presence to an attempt to discover why
it is there. Sampling should always be carried out with full aseptic precautions.
The best site for exploratory puncture (or thoracentesis) is decided after
careful scrutiny of postero-anterior and lateral films, and the puncture is
made with a needle mounted on a syringe after infiltration with a local
anaesthetic right down to the pleura. In an average case the seventh or eighth
interspace in the mid-axillary line is a suitable site. The patient may either
be sitting up and leaning slightly forwards with the arms resting on a
bed-table, or lying on his side with the site of the effusion uppermost.
Prognosis (Pleurisy)
12:41 PM
Pleurisy
Any individual with a hemithorax half filled, or more,
with fluid is in danger on this account alone. It is true that the danger is
not great but the potentialities constitute a definite threat to life. The more
immediate prognosis in general terms has been well summarized (Wood, 1946) as
depending not so much on the extent of the infection as on the unpredictable
liability at any stage to acute miliary dissemination.
Complications (Pleurisy)
12:40 PM
Pleurisy
These can be considered in two groups : (1) those
which are complications of an active tuberculous process and (2) those which
are complications of the presence of fluid in the chest.
Complications of the tuberculous process
The complications of the tuberculous process are chronicity
and dissemination. These are, of course, interconnected, and the chronicity of
an effusion and the serial involvement of the opposite pleural space often go
hand in hand. Dissemination may be on a limited scale, or it may be
widespread, resulting in miliary tuberculosis, with the picture dominated by
meningitis. Other sites to which dissemination commonly takes place are the
pericardium, the peritoneum and the genito-urinary system. In the unstable and
febrile phase of an effusion, dissemination and acute miliary spread are
ever-present dangers.
Clinical course (Pleurisy)
12:39 PM
Pleurisy
Perhaps
most typically the primary effusion proclaims its presence with malaise and
discomfort in breathing. The course of
the illness is generally favourable.
The temperature subsides in the space of 2 weeks or
so, the fluid is absorbed, function returns and the patient " recovers
". Death in the acute phase of the effusion is rare so that opportunities

Types of tuberculous pleurisy
12:37 PM
Pleurisy
There
are two main varieties of tuberculous effusion :
(1)
occurring
as a late primary manifestation ;
(2)
due
to the presence sub-pleurally of post-primary foci.
Both groups sometimes
continue to a tuberculous empyema. The second occurs perhaps, more usually in
middle-aged or elderly subjects and is generally very chronic.
Pleurisy with effusion
11:22 AM
Pleurisy
Effusion may
develop insidiously or it may follow or be accompanied by pleuritic pain.
Fluid, in considerable quantities, can accumulate without symptoms if it
collects slowly and the patient is thus given time to adjust to its presence
gradually. On the other hand, it may sometimes accumulate with great rapidity,
in which case distress and dyspnoea may become urgent.
Pleurisy without effusion
9:11 AM
Pleurisy
Dry pleurisy, whatever its cause, is
a painful condition characterized by knife-like pain related to the respiratory
excursion, which it tends to inhibit locally. The pain is not of critically
sudden onset, and careful interrogation will generally distinguish it from
intercostal neuralgia, fibrositis and pre-eruptive herpes. Friction is the
cardinal sign and must always be sought. The friction has a rubbing, grating or
scratching quality and, if coarse, can be palpated with the flat of the hand.
Pressure with the hand will often cause the pain to disappear, and pressure
with the chest-piece of the stethoscope may diminish, or even abolish, the
friction sound while pressure is maintained. Friction in a peculiar way sou
PLEURISY
8:57 AM
Pleurisy
Pleurisy implies inflammation of the pleural
surfaces, whether (1) fibrinous, (2) serous with effusion or (3) purulent. The
most important single' cause of pleurisy, whether acute or chronic, dry or with
effusion, is tuberculosis. Pneumonic consolidation—whatever
the causative organism—single or multiple pulmonary abscess and primary or
secondary neoplasia may also be accompanied by pleurisy, as may complicated
bronchiectasis. Rarely, pleurisy complicates acute rheumatism. It may occur in
nephritis, often terminally, or during the course of blood diseases such as
leukaemia. Diaphragmatic pleurisy, with shoulder-tip pain, and mediastinal
pleurisy—both localizations with
