Uterine balloon tamponade is the first-line treatment for postpartum hemorrhage (PPH). However, as cases accumulate, the disadvantages of conventional balloons, such as difficulties with insertion, displacement, dislodgement, slipping outside, and occlusion of the drainage tube with blood clots, have become evident. The newly developed Atom uterine hemostatic balloon has a stylet designed as an insertion guide for smooth insertion. The end of the insufflation portion can be housed in the handle tip of the stylet inserted into the other drainage tube to facilitate retrograde insertion of the balloon and prevent damage to the cervical canal during cesarean section. This balloon was designed in the shape of an apple to prevent it from slipping off. A drainage port without projections was used to improve adhesion to the uterine luminal wall.
The Atom balloon was inserted transabdominally during cesarean section in 13 patients, transvaginally after completing cesarean section in two patients, and transvaginally after vaginal delivery in two patients. Use of the new balloon had a hemostatic effect in all cases, including a case with coagulopathy. Neither occlusion of the drainage tube nor dislodgement of the balloon was observed. There were no cases of abnormal placement, displacement, or dislodgement at the time of balloon insertion. No complications, such as cervical laceration during insertion or intrauterine infection, were observed.
