目的 利用體表子宮肌電信號的分析實現(xiàn)宮縮和非宮縮狀態(tài)的識別。方法利用MonicaAN24母胎監(jiān)護儀采集10名孕期和10名臨產(chǎn)期孕婦的子宮肌電信號，然后提取了子宮肌電信號線性和非線性特征參數(shù)及其變化率，特征參數(shù)包括均方根、峰值頻率、中值頻率、平均頻率、小波包分解系數(shù)方差和時間可逆性。使用統(tǒng)計學(xué)方法對提取的數(shù)據(jù)特征進行單因素方差分析,比較了臨產(chǎn)組和孕期組中宮縮段和非宮縮段信號的差異。結(jié)果 組內(nèi)宮縮段信號與非宮縮段信號、組間宮縮段信號與非宮縮段信號的特征差異具有統(tǒng)計學(xué)意義(P<0.05)。結(jié)論 子宮肌電信號的研究為子宮收縮的識別與監(jiān)測提供了重要的參考價值。 |

Objective To recognize the contraction and non-contraction through the analysis of electrohysterogram (EHG) from pregnant women. Methods The data were collected from 10 pregnant women under pregnancy state and 10 pregnant women under labor stateby Monica AN24 fetal Monitoring. Then,linear andnonlinear featuresand their variabilitywere extracted,including root mean square (RMS),peak frequency (PF),median frequency (MDF),mean frequency (MNF),parameters from wavelet decomposition (W4,W5) and time reversibility (Tr).Features of contraction and non-contraction were compared by statistical method. Results Features of contraction and non-contraction both indicated significant difference (P<0.05) within groups and between groups. Conclusions The study of uterine EHG signal provides an important reference value for the identification and monitoring of uterine contraction. |
