Ketamine and the pregnant uterus

  • S. Galloon
  • P. Harley


Uterine pressure, and intensity and frequency of contractions have been measured in the pregnant uterus before and after the intravenous injection of ketamine HCl. The duration of pregnancy varied from 8 to 19 weeks. In every one of 12 patients, the uterine pressure was higher after ketamine HCl, indicating a more firm and contracted uterus. The intensity and the frequency of the contractions also increased. These effects lasted between 5 to 15 minutes after one injection of ketamine HCl.

Dans l’utérus gravide, nous avons mesuré, avant et après l’injection de chlorure de kétamine par voie endoveineuse, la pression utérine, la fréquence et l’intensité des contractions. La durée de la grossesse a varié de 8 à 19 semaines. Chez chacune des 12 malades, la pression utérine était plus élevée après l’injection de chlorure de kétamine, faisant supposer un utérus plus ferme et plus contracté. La fréquence et l’intensité des contractions ont également augmenté. Ces effets, après une injection de chlorure de kétamine, persistent de cinq à quinze minutes.
