Ochsenbein–Kölble N, et al. – This study was performed to compare tocolysis with magnesium sulfate versus atosiban regarding the occurrence of short–term preterm labor and maternal side effects amid and after open fetal myelomeningocele (MMC) repair. The utilization of atosiban resulted in an almost identical short–term uterine outcome without any serious maternal complications as observed when magnesium sulfate was given. Thus, the authors recommend utilizing atosiban instead of magnesium sulfate in the context of open fetal surgery.
