[Abstract]:Objective to develop a real-time monitoring system for postpartum intrauterine pressure and its clinical application, and to provide a method for measuring the fluctuation range of postpartum intrauterine pressure. To study the relationship between postpartum intrauterine pressure and postpartum postpartum hemorrhage. Methods: a real-time monitoring system of postpartum intrauterine pressure based on balloon catheter was developed and its clinical application. 195 pregnant women with no high risk factors were selected from March 10 to March 2013.The postpartum intrauterine pressure was measured. The range of intrauterine pressure fluctuation in 2 hours postpartum was calculated and the curve of intrauterine pressure fluctuation in 2 hours postpartum was plotted. At the same time the amount of postpartum hemorrhage was measured and the linear relationship was analyzed to study the correlation between them. Results A real-time monitoring system for postpartum intrauterine pressure was developed, including postpartum intrauterine pressure measurement balloon, digital pressure gauge, data recording and tracing system. Complications such as cervical injury.) the range of intrauterine pressure fluctuation within 2 hours postpartum was: 36 ~ 189mm Hg, and the curve of intrauterine pressure fluctuation within 2 hours postpartum was plotted. The linear correlation coefficient between intrauterine pressure at 2 hours postpartum and bleeding volume at 2 hours postpartum was r = -0.766p ~ (0. 000) < 0. 01, which was negatively correlated with that of intrauterine pressure at 2 hours postpartum. The linear regression coefficient of intrauterine pressure at 2 hours postpartum and bleeding volume at 2 hours postpartum was significant, and the linear regression coefficient (btr-0. 743) was less than 0. 01, and the difference was statistically significant (P < 0. 01, P < 0. 01). Conclusion the developed real-time monitoring system for postpartum intrauterine pressure is safe and feasible. It can be used to monitor the characteristics of postpartum uterine physiological activity. In this study, the fluctuation range of postpartum intrauterine pressure was measured and the fluctuation curve was plotted. The objective physiological indexes for monitoring uterine contraction in vaginal delivery were determined. To provide a basis for clinical prediction and early diagnosis and treatment of postpartum hemorrhage due to uterine atony in vaginal delivery. (3) there was a linear correlation and linear regression relationship between postpartum intrauterine pressure and postpartum blood loss, that is, good uterine contraction and high intrauterine pressure. The amount of postpartum hemorrhage is less, the incidence of postpartum hemorrhage is relatively low, on the contrary, the uterine contraction is not good, the intrauterine pressure is low, the amount of postpartum hemorrhage is much, the incidence of postpartum hemorrhage is relatively high.
