Placental abruption following placement of disposable intrauterine pressure transducer system.

There have been few reported complications of intrauterine pressure monitoring. We present four cases of placental abruption following insertion of a disposable intrauterine pressure transducer system (INTRAN). All four patients had placental abruptions, which were evident soon after insertion of the disposable intrauterine pressure transducer system (all of our cases had predisposing factors or signs of placental abruption at presentation). Whether there was a preexisting placental abruption, which was caused, revealed, or worsened by insertion of the disposable intrauterine pressure transducer system is unclear. We encourage careful patient selection with gentle insertion of the system opposite the placental site.
