Perhydrit and @entity4388 were administered to 99 @entity1 during the second stage of labor. Gas analysis was done twice at the beginning and the end of the second stage. The results showed that 33 @entity1 received both perhydrit and @entity4388 (Group I) had significantly higher pH, BE, @entity4095 , and O2sat at the end of the second stage than those of 30 controls (Group III) (P < 0.05 and < 0.01). And 33 @entity1 received only @entity4388 (Group II) showed merely higher pH and BE than those of Group III. The difference was significant(P < 0.05 and < 0.01), while @entity4095 and O2sat had no statistical difference between Group II and Group III. By comparing the values, we found that pH, @entity4095 and O2sat were much higher at the end of the second stage in Group I and Group II than those at the beginning of the second stage(P < 0.05 and < 0.01). No statistical difference of BE had been found between both groups. In contrary, BE, pH, @entity4095 and O2sat declined at the end of the second stage in Group III (P < 0.02 and < 0.01). There were no significant differences of PCO2 among the three groups. It is suggested that the administration of perhydrit and @entity4388 may effectively improve the tendency of maternal @entity520 and tissue @entity26 debt caused by consumption and uterine contractions during the second stage, subsequently improve maternal gases and acid-base status.
