【摘要】：目的探讨空间定位系统在宫颈扩张及胎头下降程度评估方面与传统阴道指检的相关性,以及利用空间定位系统评估产程进展速度。方法选择2014年1-5月在南方医科大学南方医院分娩的182例足月单胎、头先露、无妊娠合并症或并发症且处于分娩第一产程活跃期的健康孕产妇。分别应用低磁场空间定位系统与阴道指检监测宫颈扩张及胎头下降程度,比较两者的相关性并评估产程进展速度。结果 (1)误差分析:1宫颈扩张:空间定位系统与传统阴道指检测量平均值为(5.83±2.32)cm与(5.82±2.40)cm(P0.05),绝对误差平均值为(0.21±0.14)cm。2胎头下降:空间定位系统与传统阴道指检测量平均值为(-1.40±1.47)cm与(-1.44±1.59)cm(P0.05),绝对误差平均值为(0.32±0.24)cm;以1 cm间距分组,两指标误差及绝对误差均0.5 cm。(2)线性回归分析:1宫颈扩张:Y阴道指检=1.03 X空间定位系统-0.19(R2=0.989,r=0.995,P0.05)。2胎头下降:Y阴道指检=1.05 X空间定位系统+0.03(R2=0.939,r=0.969,P0.05)。(3)产程进展速度:1以宫颈扩张程度分组:当宫颈扩张6 cm时胎头下降均-1 cm,且与宫颈扩张6 cm时对应胎头下降程度间差异有统计学意义(P0.05);2以胎头下降程度分组:当胎头下降-1 cm时宫颈扩张均近似6 cm,且当胎头下降介于(-1,0)cm时对应宫颈扩张程度与其他分组间差异有统计学意义(P0.05)。结论空间定位系统与传统阴道指检在产程监测方面呈高度相关,前者精确性更高,并且发现产程进展速度与既往有所不同。
[Abstract]:Objective to investigate the correlation between the spatial positioning system and the traditional vaginal finger examination in the evaluation of cervical dilation and fetal head decline. The rate of labor progress was evaluated by spatial positioning system. Methods A total of 182 cases of full-term single fetus delivered in the Southern Hospital of Southern Medical University from January to May in 2014 were selected. Healthy pregnant women without complications or complications during the first stage of labor were monitored for cervical dilatation and fetal head decline by using a low magnetic field spatial positioning system and a vaginal finger biopsy, respectively. Results 1) error analysis: cervical dilatation: the mean values of spatial positioning system and traditional vaginal finger examination were 5.83 卤2.32 cm and 5.82 卤2.40 cm 路cm ~ (-1) P0.05, and the absolute average error was 0.21 卤0.14 cm ~ (2) cm ~ (2). The average value of absolute error was 0.21 卤0.14 cm ~ (2). The mean values of the localization system and the traditional vaginal finger examination were -1.40 卤1.47 cm and 1.44 卤1.59 cm 路cm ~ (-1), respectively, and the mean absolute error was 0.32 卤0.24 cm, which was grouped at a distance of 1 cm. Linear regression analysis of 1. 03 X space location system for cervical dilatation: y vaginal finger examination-0. 19% R2P 0. 989 nipple 0.995P 0. 05.2 head down 1. 05 X space positioning system for 0. 03% Y vaginal finger examination, 0. 03% R20.939 ru 0. 9699 P0. 05 P0. 05) birth progress speed: 1) with cervix dilatation. Grade group: when cervical dilatation was 6 cm, fetal head decreased by 1 cm, and there was a significant difference between fetal head and cervical dilatation at 6 cm. There was a significant difference between fetal head and cervical dilatation when cervix was dilated 6 cm. There was a significant difference between fetal head and cervix when cervix was dilated 6 cm. It was similar to 6 cm, and there was significant difference between the cervical dilatation degree and the other groups when the fetal head decreased between -1 and 0 cm. Conclusion there is a high correlation between the spatial positioning system and the traditional vaginal finger examination in the monitoring of labor process. The former was more accurate and found that the rate of progression of labor was different from that of the past.
