To explore the feasibility and effectiveness of sand table simulation training in obstetrics training.

The training class conducted training on critical obstetric disease and midwifery techniques in the form of sand table simulation, and adopted the training mode of "sand table rehearsal--trainees′ operation--tutor′s comment--tutor′s demonstration" , including eclampsia, postpartum hemorrhage, shoulder dystocia, vaginal midwifery and neonatal asphyxia resuscitation. 200 trainees were randomly divided into 5 teams as the research objects. Trainees were assessed on theoretical knowledge and operational skills before and after the training, and were graded by the tutor group according to the assessment criteria, and the rescue process of each team was assessed and scored.

After training, the score of theoretical assessment (91.1±14.5) was significantly higher than that before (75.6±24.0), the difference has statistically significant (P<0.05). After training, the scores of each operation module includes before and after training scores: eclampsia (73.7±5.6) and (90.6±3.9), postpartum hemorrhage (71.2±8.7) and (88.9±4.8), vaginal Midwifery (70.1±7.9) and (90.0±4.8), shoulder dystocia (74.6±5.7) and (91.5±2.3), neonatal asphyxia (73.2±4.7) and (91.2±2.5). The scores were significantly improved with statistic difference (P<0.05). The results of TOPSIS analysis show that team 3 is the best in many indicators, ranking first in comprehensive ranking, especially in scheme design. Team 5 has outstanding clinical skills, and done well in team cooperation and patient communication. All indicators of team 2 and team 4 are underperforming.

Most of the members of team 3 come from three-A hospitals and often participate in obstetric simulation training courses and their overall quality is high. While most of the members of team 2 and team 4 come from the basic hospitals and receive less training, their performance is weak especially in the aspects of process, communication and team cooperation, etc. It shows that they need further strengthen training. As a new type of experiential training mode, sand table simulation training is innovative, interactive, interesting and pratical significance, it has great development prospects in the emergency training of obstetrics and critical illness.
