SEMINAR ON PULMONARY
TUBERCULOSIS
Tuberculosis (TB) is one of the most prevalent
infections of human beings and contributes
considerably to illness and death around the world. It
is spread by inhaling tiny droplets of saliva from the
coughs or sneezes of an infected person.it is a slowly
granulomatous spreading, bacterial chronic,
infection, characterized by gradual weight loss
Tuberculosis is the infectious disease primarily
affecting lung parenchyma is most often caused by
mycobacterium tuberculosis. It may spread to any
part of the body including meninges, kidney, bones
and lymphnodes.

world.

world's population (3.1 billion) is infected with
Mycobacterium tuberculosis

IF MILIARYTB;A physical exam may show:
 Swollen liver

 Swollen spleen
Tests may include:
 Biopsy of the affected tissue (rare)
 Bronchoscopy
 Chest CT scan
 Chest x-ray
 Interferon-gamma release blood test such as the
QFT-Gold test to test forTB infection
 Sputum examination and cultures
 Thoracentesis
 Tuberculin skin test (also called a PPD test)
QFT-Gold test measures interferon-
gamma in the testee's blood after incubating
the blood with specific antigens from M.
Tuberculosis proteins
 0.1 ML OF PPD IS INJECTED FOREARM(SC)
 AFTER 48-72 HRS CHECK FOR INDURATION AT
THE SITE
 IF INDURATION IS EQUALTO AND MORETHAN
10MM
 POSITIVE
 Bones-Spinal pain and joint destruction may result
fromTB that infects your bones(TB spine or potss
spine)
 Brain(meningitis)
 Liver or kidneys
 Heart(cardiac tamponade)
 Pleural effusion Tb pneumonia
 Serious reactions to drug therapy(hepato toxicity,
hypersentivity)
PULMONARYTB is treated primarily with
antituberculosis agents for 6 to 12 months.
Pharmacological management
 First line antitubercular medications
 Streptomycin 15mg/kg
 Isoniazid or INH(Nydrazid) 5 mg/kg(300 mg max
perday)
 Rifampin 10 mg/kg
 Pyrazinamide 15 – 30 mg/kg
 Ethambutol(Myambutol) 15 -25 mg/kg daily for 8
weeks and continuing for up to 4 to 7 months
Second line medications
 Capreomycin 12 -15 mg/kg
 Ethionamide 15mg/kg
 Para aminosalycilate sodium 200 - 300 mg/kg
 Cycloserine 15 mg/kg
 Vitamin b(pyridoxine) usually adminstered with INH
THIRD LINE DRUGS
Other drugs that may be useful, but are not on the
WHO list of SLDs:
 Rifabutin
 Macrolides:e.g.,clarithromycin (CLR)
 Linezolid(LZD)
 Thioacetazone(T)
 Thioridazine
 Arginine
DOTS (directly observed treatment, short-course), is
the name given to theWorld Health Organization-
recommended tuberculosis control strategy that
combines five components:
1. Government commitment (including both political will at
all levels, and establishing a centralized and prioritized
system ofTB monitoring, recording and training)
2. Case detection by sputum smear microscopy
3. Standardized treatment regimen directly observed by a
healthcare worker or community health worker for at
least the first two months
4. A regular drug supply
5. A standardized recording and reporting system that
allows assessment of treatment results
DOT is especially critical for patients with drug
resistantTB, HIV-infected patients, and those on
intermittent treatment regimens (i.e., 2 or 3 times
weekly)DOT is especially critical for patients with
drug resistantTB, HIV-infected patients, and those
on intermittent treatment regimens (i.e., 2 or 3

MEDICATION:
 INTENSIVE PHASE (2-3 MONTHS)
UNDER DIRECT SUPERVISION OF HEALTH
WORKER ORTRIANED PROFFESSIONAL.
 CONTINUATION PHASE (4-6 MONTHS)
A MULTI BLISTER COMBI PACKWITH DRUGS IS
GIVEN OFWHICHTHE FIRST DOSE ISTAKEN
UNDER SUPERVISION.
 Multiple-drug therapy to treatTB means taking
several different anti tubercular drugs at the same
time.
 The standard treatment isoniazid, rifampin,
ethambutol, is to take and pyrazinamide for 2
months.Treatment is then continued for at least
4months with fewer medicines.
 MDR-TB is caused by strains of Micobacterium
Tuberculosis is resistant to both Refampicin and
Isoniazid with or without resistance to other drugs.
 Single isoniazid or refampicin resistnace is not
MDR-TB.
 MDR-TB is a laboratory diagnosis, not a clinical
assumption.
 Assessment
 Obtain history of exposure toTB
 Assess for symptoms of active disease
 Auscultate lungs for crackles
 During drug therapy assess for liver function
1.Ineffective breathing pattern related to
pulmonary infection and potential for long term
scarring with decreased lung capacity
Interventions
 Administer and teach self administration of
medications ordered
 Encourage rest and avoidance of exertion
 Moniter breath sounds respiratory rates ,sputum
production and dyspnoea
 Provide supplymental oxygen as ordered
 Encourage increased fluid intake
 Instruct about best position to facilitate drainage
2.Risk for spreading infection related to nature
of disease and patients symptoms
 Be aware thatTB is transmitted by respiratory
droplets
 Use high efficiency particulate masks for high risk
procedures including endoscopy
 Educate patient to control the spread of infection by
covering mouth and nose while coughing and
sneezing
 Isolation of patient
 Instruct about risk of drug resistance if drug
regimen is not strictly and continuosly followed
3.Imbalanced nutrition less than body
requirement related to poor appetite ,fatique and
productive cough
 Explain the importance of eating nutritious diet to
promote healing and defense against infection
 Provide small frequent meals
 Moniter weight of the patient
 Administer vitamin supplyments as ordered
4.Non compliance related to lack of motivation
and lack of treatment
 Educate patient about etiology transmission and
effects ofTB
 Review adverse effects of drug therapy
 Participate in observation of medicine
taking,weekly pill counts or programmes designed
to increase compliance with the treatment forTB
 Explain thatTB is a communicable disease and that
taking medications is most effective way of
preventing transmission
 Instruct about medications schecule and side effects
 ISOLATION
 Ventilate the room
 Cover the mouth
 Wear mask
 Finish entire course of medication
 vaccinations
 Despite all the national programmes and
efforts by the Govt. of IndiaTB still continues
to be a major socio economic burden of the
country.
 Still there is a need to awareness among the
health care workers and medical
proffessional and most importantly the
community.
