Ventilation with low tidal volumes during upper abdominal surgery does not improve postoperative lung function

Abstract

Prolonged impaired lung function after major abdominal surgery is not ameliorated by low tidal volume ventilation.

Effect of lung-protective ventilation with lower tidal volumes on clinical outcomes among patients undergoing surgery: a meta-analysis of randomized controlled trials

“…Treschan et al 33 9 ± 17 5 ± 8 0 .30 (-0.09 to 0.69) Wrigge et al 23 2.1 ± 1.9 1.2 ± 0.5 0.64 (0.03 to 1.24)…”

Lung protective ventilation strategies in routine anaesthetic practice: ready for prime time?

“…Both groups received the same PEEP (5 cm H 2 O) and both were ventilated to normocapnia. They did not find any significant differences in the postoperative lung function between the 2 groups 32 . In an observational study, Fernández-Pérez et al 23 analysed the charts of 170 patients who underwent pneumonectomy.…”

“…They found a trend towards less pulmonary infections and less time on mechanical ventilation in the low VT group. Treschan et al 32 investigated 101 patients, undergoing upper abdominal surgery, in low VT and high VT groups and compared postoperative spirometry results. Both groups received the same PEEP (5 cm H 2 O) and both were ventilated to normocapnia.…”

Comparative analysis of parameters of oxygenation, ventilation and acid-base status during intraoperative application of conventional and protective lung ventilation

“…demonstrirali su u svom istraživanju da primena Vt od 6 ml/kg tokom velikih operacija u abdominalnoj hirurgiji nije ublažila pogoršanje plućne funkcije u postoperativnom periodu u odnosu na konvencionalnu ventilaciju sa disajnim volumenom od 12 ml/kg i PEEP-om od 5 cm H 2 O [18].…”
