Objective To investigate the influencing factors of the increase of cesarean section rate and nursing intervention measures. Methods From Jul. 2013 to Jul. 2015, a total of 3320 parturient women in our hospital were chosen as the clinical objects and their data were retrospectively analyzed. The cesarean section rates in different years were calculated respectively, and at the same time, the influencing factors of the increase of cesarean section rate were analyzed. Results From 2013 to 2014, cesarean section of cesarean section was mainly composed of caesarean section and soft birth canal. In 2014-2015, cesarean section of cesarean section was composed of caesarean section and large foetus, which was mainly abnormal in soft birth canal and non-medical indication. The difference was statistically significant (P<0.05). The total cesarean section rate in 2015 rose 5.4 percentage points compared with 2013, and the difference was statistically significant (P<0.05). Conclusion The influencing factors of high cesarean section rate mainly include iatrogenic and social factors, and the trend is rising year by year. Therefore, in order to effectively reduce cesarean section rate, the propaganda and education for pregnant women and their family members in pregnant and perinatal period should be strengthened, and the indications of cesarean section should be strictly controlled.
