Gas exchange, ventilator settings, vital signs, inflammatory response, and nutrition status were examined preprocedure and 24\u00a0h and 1\u00a0week postprocedure.

Patients were classified into effective and ineffective groups according to a 110% increase in the P\/F ratio 1\u00a0week postdrainage compared with predrainage. The predrainage P\/F ratio was lower in the effective group than in the ineffective group (165\u00a0\u00b1\u00a091 versus 217\u00a0\u00b1\u00a074, <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.05).
