Abstract:
Objective To observe the effects of pressure control ventilation with volume guar-antee (PCV-VG)on the pulmonary function during percutaneous nephrolithotomy procedures in pa-tients with general anesthesia.Methods Forty patients scheduled for percutaneous nephrolithotomy were selected and randomly allocated into PCV-VG group (n =20)and volume controlled ventilation (VCV)group (n =20).For two modes of ventilation,the goal tidal volume was 6-8 ml/kg,and the respiratory rate was contralled to 12-20 bpm.PA-a O 2 ,OI,RI,Ppk,Pmean,Cst,Hct,Lac were re-corded at intubation (T0 ),1 5 min (T1 ),30 min (T2 ),60 min (T3 ),and 120 min (L4 )after intuba-tion.Results PCV-VG resulted in significantly lower PA-a O 2 ,RI,Ppk,Pmean compared with VC ventilation (P < 0.05 or P < 0.01 ),and significantly higher OI,Cst versus VC ventilation (P <0.05 or P < 0.01).Conclusion In general anesthesia patients undergoing percutaneous nephrolithoto-my,PCV-VG is superior to VCV in terms of lower airway pressure and more stable hemodynamics, thus protects pulmonary function.
