Resumen

Estudiamos el patrón de la actividad somática fetal al final de la gestación y durante el trabajo de parto. Comparamos los movimientos fetales anteparto (100 casos), durante la fase pasiva del parto (100 casos) y la fase activa (100 casos) registrados mediante un cinetocardiotocógrafo. Se utilizó un modelo informático experimental para el análisis de los movimientos, tanto de forma cuantitativa (número y porcentaje) como cualitativa (pequeña, mediana y larga duración). El número de movimientos fue mayor en la fase anteparto (45,8), seguido de la fase pasiva (32,5) y de la activa (26,3) (p < 0,0001). Idéntica significación estadística se obtuvo al comparar el porcentaje de movimientos entre las tres fases (12,5, 6,9 y 5,4%, respectivamente). La comparación por tipos de movimientos fue igualmente significativa

La actividad somática fetal es menor durante el trabajo de parto que al final de la gestación. Dicha actividad se modifica en menor grado en relación con las dos fases del parto

We studied patterns of fetal body movement at the end of gestation and during delivey. We compared fetal movements before labor (100 cases), during the passive labor phase (100 cases) and during the active phase (100 cases). Movements were recorded with a kinetocardiotocograph. An experimental computer model was used to analyze movement, both quantitatively (number and percentage) and qualitatively (small movements and those of medium and long duration). The number of movements was greatest before delivery (45.8), followed by the passive phase (32.5) and the active phase (26.3) (p < 0.0001). Comparison ofthe percentage of movements among the three phases (12.5, 6.9 and 5.4%) revealed the same statistical significance. Comparison of types of movements also yielded the same significance. Fetal activity is lesser during delivery than at the end of gestation

This activity is modified to a lesser degree during the two delivery phases
