title: Tourniquet device for hemorrhage control during cesarean section of complete placenta previa pregnancies.
abstract: OBJECTIVE
  To reduce massive and potentially fatal hemorrhage during cesarean section (CS) delivery because of the transverse incision through the lower uterine segment and placenta in central placenta previa (CPP), especially the type in which the placenta attaches to the anterior wall of the uterus.
  
  
  METHODS
  Thirty-four patients with CPP were enrolled in the study and 14 of them accepted the tourniquet method. The main outcome evaluations were blood loss, the proportion of red blood cell-transfused patients, the need for other hemostatic procedures and complications in either the mother or infant after the completion of the tourniquet procedure.
  
  
  RESULTS
  A statistically significant benefit was noted between the two groups of the frequency of post-partum hemorrhage (PPH), the median estimated blood loss and the proportion of transfused patients. The effectiveness of the tourniquet method could be further proved by the relative risk with confidence intervals for PPH data and additional procedures.
  
  
  CONCLUSIONS
  The clinical data of 34 patients show that this is an effective surgical treatment to reduce blood loss and suggest that there is negligible harm to patients and fetuses.
