Influence of enflurane on blood loss from the pregnant uterus

Uterine blood loss was measured in women undergoing therapeutic abortion during the first trimester of pregnancy. A first group, operated under paracervical block anesthesia, had a mean blood loss of 17 ml. The second group, anesthetized with pentothal, nitrous oxide and enflurane 1%, had a mean loss of 41 ml. The difference is statistically highly significant, but absolute blood losses remained small in both groups.
