【摘要】：目的：（1）研制发明产后子宫内压实时监测系统并临床应用，提供产后子宫生理活动特点研究一种方法；（2）测定产后子宫内压的波动范围，绘制产后子宫内压波动曲线图；（3）研究产后子宫内压与阴道分娩宫缩乏力性产后出血的相关性。方法：研制发明基于球囊导管的产后子宫内压实时监测系统并临床应用。选择2013.10-2013.12在我院阴道分娩的无高危因素的足月初产妇195例，测定其产后子宫内压，计算产后2小时子宫内压波动范围，绘制产后2小时子宫内压波动曲线图，同时测量产后出血量，并进行线性关系分析，研究两者之间的相关性。结果：（1）研制发明的产后子宫内压实时监测系统包括产后子宫内压测定球囊、数字式压力表、数据记录及描计系统，临床应用后效果好、产妇耐受性好,无感染、宫颈损伤等并发症发生。（2）产后2小时子宫内压波动范围：36～189mmHg，并可绘制出产后2小时子宫内压波动曲线图。（3）产后2小时子宫内压和产后2小时出血量的线性相关系数r=-0.766，P=0.000＜0.01，呈负相关，差异具有统计学意义；产后2小时子宫内压和产后2小时出血量的线性回归系数b=-0.743，P=0.000＜0.01，差异具有统计学意义。结论：（1）研制发明的产后子宫内压实时监测系统安全、可行，可用于监测产后子宫生理活动特点。（2）本研究测定了产后子宫内压波动范围并绘制波动曲线图，明确了阴道分娩子宫收缩情况监测的生理学客观指标，为临床预测并早期诊断治疗阴道分娩宫缩乏力性产后出血提供研究基础。（3）产后2小时子宫内压和产后2小时出血量呈线性相关和线性回归关系，即子宫收缩好，，子宫内压高，产后出血量少，产后出血发生率就比较低，反之子宫收缩状况不好，子宫内压低，产后出血量多，产后出血发生率就比较高。
[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.
