Primary graft dysfunction (PGD) is a form of acute lung injury that occurs in the immediate postoperative period. It is associated with 30% of all deaths in the immediate postoperative period. The characteristics of PGD are similar to ARDS and as follows: | |||
* Hypoxemia with pulmonary infiltrates in absence of left heart failure | |||
* New diagnosis of pulmonary hypertension in immediate postoperative period | |||
* Otherwise unexplained respiratory failure | |||
There are many independent risk factors for PGD including (many of these are modifiable risk factors): | |||
* Overweight and obesity | |||
* Preoperative pulmonary hypertension or sarcoidosis | |||
* Use of cardiopulmonary bypass | |||
* Single lung transplantation | |||
* Increased FiO2 during allograft reperfusion | |||
* Blood products administered during surgery | |||
* Donor age less than 21 or greater than 45 years old, female gender, smoker, and African American in origin | |||
Treatment for PGD consists of lung protective ventilation, similar to ARDS. Pulmonary vasodilators such as iNO and Iloprost have been used. Severe cases may require ECMO support. | |||

Primary Graft Dysfunction (PGD)[3]
Primary graft dysfunction (PGD) is a form of acute lung injury that occurs in the immediate postoperative period. It is associated with 30% of all deaths in the immediate postoperative period. The characteristics of PGD are similar to ARDS and as follows:
- Hypoxemia with pulmonary infiltrates in absence of left heart failure
- New diagnosis of pulmonary hypertension in immediate postoperative period
- Otherwise unexplained respiratory failure
There are many independent risk factors for PGD including (many of these are modifiable risk factors):
- Overweight and obesity
- Preoperative pulmonary hypertension or sarcoidosis
- Use of cardiopulmonary bypass
- Single lung transplantation
- Increased FiO2 during allograft reperfusion
- Blood products administered during surgery
- Donor age less than 21 or greater than 45 years old, female gender, smoker, and African American in origin
Treatment for PGD consists of lung protective ventilation, similar to ARDS. Pulmonary vasodilators such as iNO and Iloprost have been used. Severe cases may require ECMO support.
