In order to known more about preterm labor the objective of our investigation was to look for a correlation between the spatial and temporal pattern of uterine contractions and the duration of pregnancy. 50 patients with preterm labor between 21 and 35 weeks of gestation underwent repeated measurements using four-channel tocography in which the pressure of contractions was registered simultaneously on the left and right sides at the fundus and the lower segment of the uterus. Half of all recorded signals were locally restricted (typical labor pattern in only one or two registration tracks). The following two phenomena were significantly associated with a shorter duration of pregnancy: 1. the reproducibility of a center of dominance (defined as the locus of registration with the highest sum of amplitudes), and 2. a predominant origin of labor in the right fundal region of the uterus. Four-channel tocography indicates whether preterm labor is likely to lead to preterm delivery. It may therefore help the obstetrician in deciding whether to use tocolytic therapy.
为了更深入了解早产，我们研究的目的是探寻子宫收缩的时空模式与妊娠时长之间的关联。50名妊娠21至35周的早产患者接受了使用四通道宫缩图的重复测量，在该测量中，宫缩压力在子宫底部和下段的左右两侧同时记录。所有记录信号的一半是局部受限的（仅在一两个记录通道中出现典型的分娩模式）。以下两种现象与较短的妊娠时长显著相关：1. 优势中心的可重复性（定义为振幅总和最高的记录位点），以及2. 子宫右底部区域为主的分娩起始部位。四通道宫缩图可表明早产是否可能导致早产分娩。因此，它可能有助于产科医生决定是否使用宫缩抑制疗法。
