A lung transplant is considered the last option for the treatment of respiratory failure and may be required in the end stages of the following conditions :
- Chronic obstructive pulmonary disease (COPD): is a chronic lung condition that results in obstruction of the airflow. This results in difficulty in breathing, productive cough and wheezing. Commonly seen amongst chronic smokers.
- Cystic Fibrosis: It is an inherited life-threatening disorder (seen mainly in Caucasian race) that results in the affection of cells producing mucus, sweat, and digestive juices that cause death overtime.
- Pulmonary hypertension: It is an abnormal increase in the blood pressure in the arteries of the lungs usually caused by an untreated hole in the heart. Results in right-sided heart failure.
- Pulmonary fibrosis: When lung interstitial tissues get scarred and thickened.It has the worst prognosis among all lung diseases.
- Routine blood investigations
- V/Q Scan
- Pulmonary function test
- Chest HRCT
- ECG and 2 D Echocardiogram
- Coronary Angiogram
- CTPA and CPET
- Women need to get a Pap smear, gynecology evaluation, and a mammogram.
The steps of procedure for the Lung Transpant Surgery are-
- A plastic tag and bracelet with name and number is assigned to the patient.
- An IV (intravenous line) is inserted into the arm of the patient before the surgery begins.
- Then the venous catheters are placed in the neck and groin of the patient. Also, BP monitoring lines are inserted in the radial and femoral arteries. A Urinary catheter is also placed and a nasogastric tube is placed in the stomach.
- General anesthesia is given to the patient and a breathing tube is put into the throat. The patient is attached to the ventilator.
- An incision is made by the surgeon in the chest. Usually, for a bilateral sequential transplant, the incision is going to be made horizontally across the chest below the breasts.
- The patient is placed on cardiopulmonary bypass using a heart-lung machine.
- The diseased lungs are removed and replaced with the donor’s lungs.
- 4-6 drainage tubes are put in the patient’s chest.
The risks of lung transplant surgery include-
- Bleeding (heavy)
- Infection
- Thrombosis
- Dehiscence of the airway suture line
- Pulmonary edema
- Lung rejection
- Osteoporosis and bone fractures
- High cholesterol levels
- The patient is kept in the ICU for 1-2 weeks after the surgery. The vitals are monitored, the catheter is placed to empty the bladder and a flexible bronchoscopy is done. The ventilator is removed after 1-3 days.
- The nasogastric tube is taken out when bowels resume normal function.
- Blood samples are taken many times in a day, this is done to monitor the health of the new lungs, kidneys and liver. The patient is given opioids for pain control.
- The immunosuppressive medicines are gradually increased to monitor the bone marrow, kidney, and liver function.
- ICCU Nurses, ID doctors, and physiotherapists will monitor the patients closely.
