Efficacy of OB balloon tamponade in cesarean delivery for placenta previa and low-lying placenta: a retrospective comparative study.
Article in BMC pregnancy and childbirth, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPlacenta previa and low-lying placenta are associated with substantial peripartum hemorrhagic complications, particularly during cesarean delivery. This retrospective study compared the efficacy and safety of a newly developed OB balloon—featuring a double-balloon structure designed to simultaneously compress the uterine and vaginal sides—with the conventional Bakri balloon for intrauterine tamponade.
methodsWe retrospectively analyzed cases of placenta previa or low-lying placenta managed with either the OB or Bakri balloon during cesarean delivery. The primary outcome was balloon failure, defined as inadequate postoperative bleeding control requiring additional interventions despite balloon tamponade. Secondary outcomes included insertion time, inflation volume, postoperative blood loss, and balloon prolapse.
resultsA total of 47 cases were analyzed: 20 in the OB group and 27 in the Bakri group. Balloon failure occurred in 5 cases (18.5%) in the Bakri group—all associated with balloon prolapse—whereas no failures occurred in the OB group. Balloon prolapse was observed in 6 cases (22.2%) in the Bakri group and none in the OB group. No significant differences were found in insertion time or postoperative blood loss between the groups.
conclusionThe OB balloon reduced the incidence of balloon prolapse while maintaining comparable hemostatic efficacy. These findings suggest that the OB balloon offers a more stable hemostatic option for cesarean deliveries complicated by abnormal placentation.
