It has been shown that changing the maternal position during labor may have an influence on uterine contractility. WILLIAMS 1952 [9] reported on one patient, whose contractions became more intense when she was in sitting position, using internal tocography. Two years later, VON LORAND and POGANY [8], using external tocography, claimed that the recumbent position increased uterine contractions. These observations were made during spontaneous labor, in nulliparae with intact membranes. BOSCH,

BOSCH, IKLE and KÄSER 1954 [4] and CALDEYRO et al. 1960 [6] demonstrated, that uterine contractions were stronger and less frequent when the patient lay on her side (left or right), than when she was supine. When evaluating the effects of maternal position on uterine contractility, it should be recalled that several other, factors including parity, condition of the membranes and medication given to the mother, may also influence spontaneous uterine contractility and labor. The first objective of this paper is to study the effect of standing position on spontaneous uterine contractility, when these factors are taken into account. Furthermore the influence of the maternal position on the pain produced by contractions, comfort of the patient and duration of labor have not been studied, in our knowledge. An additional aim is to study the effects of standing position on the duration of labor, pain produced by uterine contractions and comfort Curriculum vitae CARLOS MENDEZ-BAUER was born in Montevideo (Uruguay) in 1930. He completed bis studies there and gradtiated äs Doctor in Mediane at the Faculty of Medicine, University oftbe Repttblic, Montevideo (Uruguay). In 1952 be joined the Service of Obstetrical Physiology, directed by R. CALDEYRO-BARCIA. Sinee tbat time he has become interested in uterine physiology, endocrinology of labor, and physiology of the fetus and newborn. In 1966 he was appointed cbief of the Service of Obstetrical Physiology>, Montevideo (Urttr guay). He moved in 1969 to USA, where he remaimd for one year äs Associate Professor of Obstetrics and Gynecology and Physiology at the University of Minnesota. Returning to Montevideo he participated in the activities of the Latin American Center of Perinatology and Human Development (CLAP), institution sponsered by P. A. H. O. (WHO). In 1973 he joined the Maternidad Santa Cristina, Madrid, Spain, to develop a program of care and research in Perinatology in cooperation with the Department s of Obstetrics, Gynecology and Neonatology. He has published severaipapers and articles in connection with perinatal Problems. of the patient since, to our knowledge these have not hitherto been studied.
