Roberto Caldeyro-Barcia, Uruguayan obstetrical physiologist (Montevideo 26 September 1921 – 02 December 1996) ACHIEVEMENTS With Hermógenes Alvarez
First obtained records of intrauterine amniotic pressure during childbirth
defining intensity, contraction rate, inner tonus and uterine activity (1947) .
These were the first records of human uterus activity during labor Established the descending triple gradient law (1949) Developed Montevideo unit of uterine performance (1949) First recorded intramiometrial pressure in distinct parts of uterus
during childbirth establishing the source and propagation of wave of uterine
contraction (1950) Established two kinds of contraction during pregnancy
Established the concept of uterine tonus, its effects and variations
Described the pain, emotions and remedies influence on uterine conductivity Independent from Edward Hon described main changes of fetal cardiac
rate produced via uterine contractions which became later the basis of fetal
monitoring (1958) Eponym of Alvarez-Caldeyro Barcia microballoon Described
criteria to predict the progress of labor during delivery Showed an
original method used to diagnose early fetal asphyxia during labor (1958) Developed
methods for recording contractions of pregnant human uterus and fetal cardiac
rate Described
the first continuous cardiotachogram (1958) With
colleagues developed sub partu
tocolysis, the first medicamentous tocolysis (1969) Proposed first
uterine inhibitory treatment in the world Developed the first devices for recording uterine contractility and fetal heart rate First to record amniotic fluid, intraplacental blood and intramiometrial pressures Eponym of Caldeyro Barcia classification for decelerations (1965) HONORS President, International Federation of Gynecology and Obstetrics (1976-9) Houssay Prize, Organization of American States (1976) Medicine & Physiology Nobel Prize nominee (1994 & 1995) Asteroid Caldeyro 9478 |
