From: Short-term outcomes of cadaveric lung transplantation in ventilator-dependent patients

Variable

Number (%) or mean ± SD

Donor characteristics

 

   Ideal donor

4 (40%)

   Extended donor

6 (60%)

Reasons for extended donor classification

 

Smoking history ≥; 20 pack-years*

3

PaO2/FiO2 ratio < 350 prior to explantation

2

Presence of purulent secretions

4

Infiltrate on chest x-ray

5

Positive sputum culture results from Gram stain

4

Allograft ischemic time (minutes)

 

   First implanted donor lung

197 ± 53

   Second implanted donor lung

330 ± 68

Duration of weaning off ECMO Support (n = 10)

 

   Weaned off ECMO support in OR (n = 8)

 

Immediately after LTx (hours)

7.8 ± 2.1

   Weaned off ECMO support in ICU (n = 2)

 

Within 1 day after LTx

1 (10%)

> 1 day after LTx

1 (10%)

  1. * One pack-year is defined as one pack of cigarettes smoked per day for one year.
  2. ECMO = extracorporeal membrane oxygenation; FiO2 = fraction of inspired oxygen; LTx = lung transplantation; OR = operating room; PaO2 = partial pressure of arterial oxygen; SD = standard deviation.
