Noninvasive positive pressure ventilation for the treatment of acute respiratory distress syndrome following esophagectomy for esophageal cancer: a clinical comparative study.

OBJECTIVE

To evaluate the therapeutic efficacy of noninvasive positive pressure ventilation (NPPV) in the treatment of acute respiratory distress syndrome (ARDS) following esophagectomy for esophageal cancer.

METHODS

In this retrospective evaluation, we included 64 patients with ARDS following esophagectomy for esophageal cancer between January 2009 and December 2011. The primary evaluations were 28-day fatality and actual fatality. The secondary evaluations were sex, age, onset time, pH value, PaO2/FiO2, sequential organ failure assessment (SOFA) score, acute physiology and chronic health evaluation (APACHE-II) score, and presence or absence after surgery of major surgery-related complications such as cardiac arrest, anastomotic fistula, and acute renal dysfunction.

RESULTS

NPPV applied as the first-line intervention for ARDS following esophagectomy for esophageal cancer avoided intubation in 30 patients (30/64, 48.4%). There were no significant differences in gender, age, PaO2/FiO2, SOFA score, or APACHE-II score between the NPPV group and the patients who required invasive positive pressure ventilation (IPPV group) (P>0.05) at the time of onset, while differences in the PaO2/FiO2 (P<0.05) after 24 h of NPPV and presence of major surgery-related complications were highly significant (P<0.01).

CONCLUSIONS

NPPV may be an effective option for the treatment of ARDS/acute lung injury (ALI) following esophagectomy for esophageal cancer. However, conversion to invasive mechanical ventilation should be considered in patients with severe postoperative complications such as acute renal dysfunction and cardiac arrest and in those with PaO2/FiO2 <180 after 2 h of NPPV.
