4. Introduction :
• Lung transplantation involves removal of one
or both diseased lungs from a patient and the
replacement of the lungs with healthy organs
from a donor
• Lung transplantation may refer to single,
double, or even heart-lung transplantation .
• Lung transplantation is an accepted modality
of treatment for end stage lung disease that is
unresponsive to medical therapy
4
5. Purpose :
• To replace a lung that no longer functions with
a healthy lung.
• To perform a lung transplantation, there
should be potential for rehabilitated breathing
function.
• Other medical treatments should be
attempted before transplantation.
• Many candidates for this procedure are
dependent on oxygen therapy
5
6. History of procedure :
• Animal experimentation by various pioneers,
including Demikhov and Metras, in 1940s and
1950s demonstrated that the procedure is
feasible technically.
• First human lung transplantation was done in
1963. The donation was essentially after
cardiac death, and the recipient of the left lung
transplant survived only 18 days.
6
7. Cont……….d:
• From 1963-1978, multiple attempts at lung
transplantation failed because of rejection and
problems with anastomotic bronchial and
tracheal healing.
• The first successful single lung transplant was
reported by Dr. Joel Cooper at the University
of Toronto in 1986 .
7
8. Cont……….d:
• In 1988, Dr. Alexander Patterson described the
technique of double-lung transplantation.
• Dr. Denton Cooley and associates were the
first to attempt heart-lung transplantation in
1968.
• First heart-lung transplant in India- 3 May
1999 at Madras Medical Mission.

24
26. Contra-indication (Absolute ):
• Malignancy in the last 2 years
• Non-curable chronic extra pulmonary
infection including chronic active
hepatitis B , C , and HIV
• Untreatable advanced dysfunction of
another major organ system
• Current cigarette smoking
26
27. • Poor nutritional status
• Poor rehabilitation potential
• Significant psychosocial problems
• Substance abuse history of medical
noncompliance
27
28. Relative Contraindications :
• Age : advanced age is associated with
higher mortality rates .
• Most centers have an age cut-off
50 years for -Heart-lung transplantation,
60 years for- Bilateral lung transplantation,
65 years for -Single-lung transplantation.
28
29. • Ventilator dependence : patients who
are dependent on a ventilator prior to
the transplant have higher mortality
rates .
• A prolonged wait while the patient is on
a mechanical ventilator may lead to
various complications such as infections,
cardiovascular de-conditioning.
29
30. • Psychosocial issues : Individuals who
currently smoke, abuse drugs, or drink
alcohol heavily are not candidates for
transplantation.
• Patients with other psychosocial issues,
such as poor compliance and psychiatric
disorders that may complicate post
transplant therapy, are not considered
good candidates.
30
31. • Infection : patients who have active
tuberculosis infection are not candidates
for transplantation.
• Body weight : Patients who have poor
nutritional status and would have a poor
outcome following transplantation.
31
32. • Obesity (BMI >30) : also may be a
concern because of postoperative
atelectasis and pneumonia
• Extra pulmonary organ dysfunction :
Patients with a significant
heart, liver, or kidney disease are not
transplant candidates.
32
33. Description :
• Single lung transplantation is performed
via a standard thoracotomy (incision in
the chest wall) with the patient under
general anesthesia.
• Cardiopulmonary bypass (diversion of
blood flow from the heart) is not always
necessary for a single lung transplant.
33
34. Cont………..d:
• If bypass is necessary, it involves re-routing of
the blood through tubes to a heart-lung bypass
machine. Double lung transplantation involves
implanting the lungs as two separate lungs, and
cardiopulmonary bypass is usually required
• The patient's lung or lungs are removed and the
donor lungs are stitched into place. Drainage
tubes are inserted into the chest area to help
drain fluid, blood, and air out of the chest.
34
35. Figure
Patient positioned for bilateral lung transplant, through a clamshell incision
with the arms abducted. The skin incision is depicted in the mammary fold
heading laterally toward the mid-axillary line. The dotted line shows the
level of the 4th intercostal space. The position of the femoral artery, on both
sides, is also marked. The groin is prepped and draped, since during the
transplant procedure, an arterial femoral line may become necessary for
monitoring or even for cannulation for cardiopulmonary bypass.
35
38. Laboratory studies :
• The following diagnostic tests are usually
performed to evaluate a patient for lung
transplantation:
• Arterial blood gases (ABG ) test: which
measures the amount of oxygen that the
blood is able to carry to body tissues.
38
39. • Pulmonary function tests (PFTs): which
measure lung volume and the rate of air flow
through the lungs; the results measure the
progress of the lung disease.
• Computerized tomography (CT) scan. A chest
CT scan is taken of horizontal slices of the
chest to provide detailed images of the
structure of the chest.
39
40. • Ventilation perfusion scan (lung scan, V/Q
scan) is a test that compares right and left
lung function
• Electrocardiogram (ECG): is performed by
placing electrodes on the chest. A recording of
the electrical activity of the heart is obtained
to provide information about the rate and
rhythm of the heartbeat
40
41. • Echocardiogram (ECHO) is performed to
evaluate the impact of lung disease on the
heart. It examines the
chambers, valves, aorta, and the wall motion of
the heart.
ECHO also provides information concerning the
blood pressure in the pulmonary arteries. This
information is required to plan the
transplantation surgery.
41
42. • Blood test : Complete blood count ,
Coagulation profile.
• HIV, hepatitis B, hepatitis C
42
43. Donor-related issues:
• Younger than 65 years for lung transplantation
and younger than 45 years for heart-lung
transplantation
• Absence of severe chest trauma or infection
• Absence of prolonged cardiac arrest (heart-
lung only)
• Minimal pulmonary secretions Negative
screens for HIV, hepatitis C, and hepatitis B
43
44. • Blood type (ABO) compatibility
• Close match of lung size between donor and
recipient
• PaO2 > 300 mm Hg on 100% fraction of
inspired oxygen
• Clear chest radiograph
• No history of malignant neoplasms
44
45. Preoperative care:
• Preoperative assessment consist of both medical
& psychosocial evaluation.
• Assessment of patient‘s physical health is
assessed to determine candidacy for
transplantation.
• In preoperative phase the patient is assessed for
cardiac output & renal functions .
• Psychosocial evaluation focuses on assessing the
patient‘s history of compliance with medical
therapy & ability to cope with stress.
45
46. Post operative care :
• The patient is observed for excessive bleeding.
• Monitor vital signs ,ECG ,ABG values ,urine
output, O2 level analysis & chest tube
drainage.
• The patient may be started on mechanical
ventilation for 24 to 48 hours.
46
47. • Serum electrolytes ,complete blood count,
chest radiographs are obtained daily.
• Fluids are restricted.
• Lung sounds are auscultated.
• Severity of peripheral edema is monitored.
• Pain control is important to allow deep
breathing & coughing with chest
physiotherapy.
47
48. • The patient with lung transplantation is at high
risk to develop infection.
• So isolation is used to decrease exposure to
pathogens.
• Monitor the patient for clinical manifestation of
infection such as:
Change in vital signs especially fever
Local infection at i/v site & incision line
Changes in respiratory status like
excessive secretions, tachypnea,dyspnea
48
49. Immunosuppression
• Induction phase-
A) ATG
B) Selective IL2 receptor antagonists
• Maintenance phase-
A) Steroid + calceneurin inhibitor
B) Steroids ( low dose ) life long
C) Tacrolimus for 1-5 years
49
50. Newer drugs
1) Sirolimus (Rapamycine)- An analog of
Tacrolimus
2) Everolimus- used in combination with
cyclosporin & prednisolone shown to have
freedom from biopsy proven acute rejection
in 88% cases
50
52. Ischemia reperfusion injury
Most frequent cause of early mortality
presents as ALI / ARDS
Reduced incidence since 1990-
1) low K- dextran solution
2) nitric oxide added to flush solution
3) prevention of hyperinflation during harvesting
4)controlled reperfusion with leucocyte
depletion
52
53. Ischaemia reperfusion injury contd.
• Treatment-
A) diuretics
B) maximal ventilatory support
• Newer modalities
A) inhaled nitric oxide
B) inhaled prostacyclin
• Course-
resolves in 48-72 hrs
53
54. Infections
• Bacterial-
A) psuedomonas predominate in early post
op(75%)
B) nocardia-2.1%
C) legionella , mycobacteria rare
• routine antibiotic prophylaxis reduced the
incidence
• sputum cultures & antibiotic sensitivity done every
3 months
54
55. Viral infections
CMV predominates
• within 30-100 days after transplant
• occurs as reactivation or prim. infection
(donor)
• incidence varies between 13-75% in various
studies
• routine prophylaxis replaced by close
monitoring
• Treatment-gancyclovir 5mg/kg for 2-3 weeks55
56. • HSV&VZV can cause pnuemonia
• Acyclovir prophylaxis effective in patients not on
gancyclovir
• EBV related post-transplant lymphoproliferative
disease
• 4-10% cases
• usually fatal outcome
• recently Rituximab ( anti CD20 Ab) found effective
56
57. Fungal infections
• Aspergillus most common
1) ulcerative trachitis
2) bronchitis
3) pnuemonitis
4) disseminated diesase
5) ABPA- reported
• I.V. or aerolised ampho-B used for prophylaxis
57
60. Acute rejection
• TBLB - gold standard in diagnosis
• Noninvasive means-area of active research
1) Cytokine milieu in BAL fluid
2) gene upregulation as a biomarker
• Treatment- bolus I.V. steroids + increase in
maintenance immunosuppression
• role of surveillance bronchoscopy to detect
rejection early is controversial
60
61. Chronic rejection
Bronchiolitis Oblitrance Symdrome (BOA) :
• Predominantly a small airway disease
• occurs in 50% patients surviving for 5 years
• onset > 6months
• major cause of mortality
• CXR- can be normal late cases- bronchiectesis
• HRCT- mottled appearance with peripheral
lucency
61
62. TBLB- gold standard
• Role of induced sputum & BAL-
1) Induced sputum – RANTES levels and
eosinophils correlate with BOS
development
2) BAL- IL8 & neutrophil levels have
negative correlation
62
63. • Treatment- variable course even without
treatment
• various immunosuppressive regimens
tried
• macrolides under evaluation
63
65. Self care :
• Before discharge the patient should be teach
about the medication regimen.
• The patient should report for fever, dyspnea,
cough ,increased sputum production ,chest
pain, excessive weight gain, fatigue to
physician. During follow up the client is
monitored for manifestation of rejection &
progress in functional status.
65
66. • Exercise capacity has been the most
interesting functional outcome observes in
lung transplant recipient .
• Typically transplant recipient can walk 100
to 120m/min within 6 months of
transplantation.
66
67. Normal results:
• Demonstration of normal results for lung
transplantation patients include
a) adequate lung function,
b) improved quality of life,
c) lack of infection and rejection.
