Objective Research was performed to test how to improve the effectiveness of health education. Methods 236 patients after cesarean section, during June 1, 2015 to November 31, 2015 from Obstetrics I in our hospital were selected. According to the room number, they were randomly divided into single-number rooms, 119 people in the control group, with the aid of pictures, materials, individual or group concentrated postnatal health education, and double-number rooms, 117 people in the experimental group, based on previous education with the extra use of digital television platform. The effects of the two groups were compared. Results In the experimental group after cesarean section, patients′ anal exsufflation time for less than 24 h and more than 36 h was 41 cases and 5 cases respectively, and patients′defectation time for less than 72 h, more than 72 h and less than 96 h, more than 96 h was 45, 66 and 6 cases respectively, while compared with the control group, there was 21, 83, 15 cases respectively. The differences between the two groups were statistically significant (χ2=36.90, P < 0.05). In the experimental group, the breast-sucking times within 24 hours was (9.41 ± 1.35) times, compared with the (7.29±1.02)times in the control group. The difference between the two groups was statistically significant (t=13.76, P<0.01). In the experimental group, the incidents of newborn adding milk, neonatal jaundice and neonatal erythema was 16, 12, 20 cases respectively, compared with the 33, 25, 47 cases in the control group. The differences between the two groups were statistically significant (χ2=7.08, 5.16, 14.56, P <0.05). In the experimental group, the numbers of individual behaviors like brushing teeth and combing hair, and family consultation was 110, 110, 42 cases, while in the control group was 92, 85, 75 cases respectively. The differences between the two groups were statistically significant (χ2=13.35, 20.97, 17.36, P < 0.01). Conclusion The use of digital TV platform for postpartum maternal health education is suitable for mothers and their families, with the consideration of individual needs, parturients can watch materials repeatedly and whenever they want. The application will come out with better education results.
