ClinConnect Summary

This study will be conducted in the Affiliated Hospital of Nantong University. Sixty CRC patients are randomized into traditional ventilation strategy group (control group) and lung protective ventilation strategy group (experimental group), there were 30 cases in each group. The control group adopted conventional ventilation strategies: tidal volume (VT)=10-12 ml/kg, respiratory rate ( f)=12 breaths / minute, positive end expiratory pressure(PEEP)=0 cmH₂O, fraction of inspired oxygen =0.5; the experimental group used lung protective ventilation strategies: tidal volume ( VT)=6-8 ml/kg, f=1...
