Holding the uterine cervix may induce uterine contractions in atonic bleeding.

摘要

Sir, A textbook (1) describes a balloon catheter for atonic bleeding in the category of uterine packing. Previous reports regarding this issue indicated that hemostasis can be induced by the compression of the bleeding surface by balloon catheter. Is hemostasis brought about only by this mechanism? We read with interest the article by Yorifuji et al. (2). A balloon catheter, even though it was placed in the cervix and thus did not directly compress the uterine body lumen (bleeding surface), stopped the atonic bleeding. Acoustic radiation force impulse elastography showed an increased uterine consistency after balloon insertion, suggesting that the balloon stopped bleeding via induction of uterine contractions. This notion is new and agrees with our experience.
