Abstract:
Objective To investigate the impact of different irrigation time on oxygenation in-dex and acid-base balance during percutaneous nephrolithotomy(PCNL).Methods Forty patients un-dergoing selective PCNL were included in this study,were divided into two groups:group S,irrigation time<120 min(n=22);group L,irrigation time≥120 min(n=18).PaO2/FiO2 ,pH and BE were determined before and after irrigation,CVP were recorded before irrigation and every 20 min during irrigation. Results The CVP maximum value were higher in group L than that in group S during irrigation (P <0.05).The PaO2/FiO2 were lower after irrigation than that before irrigation in group L(P<0.05).The pH and BE were lower in group L than that in group S after irrigation(P<0.05).Conclusion Irrigation fluid absorption is observed during PCNL.That can provoke oxygenation function decline and metabolic ac-idosis with irrigation time extend,the operation time properly shortened.
