Continuous positive airway pressure for treatment of respiratory complications after abdominal surgery; a systematic review and meta-analysis. Ann Surg 2008; 247: 617-626.

Published: 1st January 2008

Authors: Ferreyra G, Baussano I, Squadrone V, Richiardi L, Marchiaro G, Del Sorbo L et al.

Conclusion

There were nine trials to analyse. Continuous positive airway pressure reduced the rate of postoperative pulmonary complications (risk ratio 0.66, 95 per cent confidence interval 0.52 to 0.85), with a number of patients needed to treat for benefit of 14.2.
