Objective. To explore the effect of comprehensive nursing intervention under internet-based WeChat platform education on postoperative recovery of puerperae undergoing cesarean section (C-section). Methods. A total of 96 patients undergoing C-section in our hospital from June 2018 to October 2021 were selected for the retrospective analysis and grouped according to the nursing intervention modes as follows: patients who received a routine nursing intervention were included in the control group, and patients who received comprehensive nursing intervention under internet-based WeChat platform education were included in the study group, with 48 cases each. After the intervention, the postoperative recovery of puerperae undergoing C-section and obstetrics nursing quality were scientifically assessed. Results. No statistical differences in general data between the two groups were observed ( P > 0.05 ). Compared with the control group, patients in the study group had obviously earlier initial time of lactation ( P < 0.05 ), significantly higher breast milk amount within 48 h after delivery ( P < 0.05 ), significantly earlier spontaneous urination time, anal exhaust time and off-bed activity time ( P < 0.05 ), obviously better mastery of health knowledge ( P < 0.05 ), and, in terms of SCL-90, remarkably lower total score, average total positive score, and the number of positive items and scores in dimensions, such as somatization, obsessive-compulsive, depression, anxiety, interpersonal sensibility, anger-hostility, phobic-anxiety, and paranoid ideation ( P < 0.05 ). At discharge, 3 months, and 6 months of follow-up, patients in the study group obtained significantly higher scores on quality of life than the control group ( P < 0.05 ). Conclusion. In the nursing of puerperae undergoing C-section, comprehensive nursing intervention measures based on the internet-based WeChat platform education can effectively improve the early lactation, mastery of health knowledge, and adverse emotions of puerpera and promote their postoperative recovery.
