title: Use of the Foley catheter versus a double balloon cervical ripening catheter in pre-induction cervical ripening in postdate primigravidae.
abstract: OBJECTIVE
  To compare the efficacy of two mechanical devices for pre-induction of labor cervical ripening: the Foley catheter and the Cook cervical ripening balloon.
  
  
  METHODS
  This interventional study included 78 postdate primigravid women randomly allocated into two groups: the Foley or Cook balloon catheter. Removal of the catheters was planned approximately 12 h after insertion if spontaneous expulsion had not occurred. The main outcome measures included changes in Bishop score, insertion to delivery time, mode of delivery and occurrence of adverse effects.
  
  
  RESULTS
  Spontaneous expulsion of the Foley catheter was encountered more frequently than the Cook (89.2% vs 78.4%; P = 0.03). However, the median Bishop score was significantly higher when using the Cook compared with the Foley catheter after balloon removal (6 vs 5; P = 0.03). The duration from balloon insertion to expulsion and from insertion to delivery was significantly shorter in the Foley group compared with the Cook balloon group (6:19 ± 2:1 vs 7:26 ± 2:25 h; P = 0.03 and 13:50 ± 4:00 vs 15:16 ± 4:30 h; P = 0.03, respectively). There were no significant differences in other outcomes, such as the amount of oxytocin units used, mode of delivery, pain encountered during or after insertion and overall patient satisfaction.
  
  
  CONCLUSIONS
  Use of the Cook cervical ripening catheter results in greater cervical ripening compared with the Foley catheter. However, the duration from balloon insertion to expulsion and then delivery were significantly shorter when using the Foley catheter; therefore, we recommend its use, particularly in low resource settings.
