Description

Brunelli et al developed the Aggregate Prolonged Air Leak (PAL) Score to evaluate a patient undergoing a pulmonary lobectomy. This can help to identify a patient who may have a prlonged air leak. The authors are from Ospedali Riuniti in Ancona, Italy, and Salamanca University Hospital in Spain.


 

Patient selection: lobectomy

 

Outcome: prolonged air leak (lasting > 5 days)

 

Parameters:

(1) age in years

(2) body mass index (BMI)

(3) FEV1 as percent of predicted ("perioperative", not stated as pre or post. After lobectomy there should be a significant drop. In the implementation pre-operative FEV1 will be used)

(4) dense pleural adhesions seen at surgery (cover an entire lobe or >= 30% of lung surfaces)

Interpretation:

• minimum score: 0

• maximum score: 5.5

• The higher the score the greater the risk of prolonged air leak.
