Abstract: Objective To investigate the effect of two modes of ventilation on pediatric patients undergoing lung lobectomy.Methods Forty ASA Ⅰ～Ⅲ patients aged 2～10 years,undergoing lung lobectomy were randomly divided into VCV and PCV group(n=20).After general anesthesia,patients in VCV group were ventilated on volume-control mode maintaining 30min and then changed into pressure-control mode;patients in PCV group were ventilated on pressure-control mode maintaining 30min and then changed into volume-control mode.Ppeak,Pplat,Raw,MVI,MVE and EtCO2 were measured according to SSS monitor system.All the patients were treated with traumatic blood pressure measurement,and all the patients were analyzed during the period of pre-operation,30min and 60min after ventilation.Results Compared with VCV group,breathing mechanics MVI and MVE in the PCV group were increased(t=4.135,3.988,P＜0.05)and PaO2 in the PCV group was significantly increased(t=3.183,P＜0.05),as compared with those on volume-control mode.Conclusion PCV mode was benefit for preventing low oxygen in lung lobectomy surgery.
