Balloon dilators for labor induction: a historical review

Area of Science:

• Obstetrics and Gynecology
• Medical History

Background:

• Current literature often attributes cervical balloon dilation for labor induction to Barnes (1860s) or Embrey and Mollison (1960s).
• This attribution overlooks earlier contributions and potential safety concerns.

Purpose of the Study:

• To accurately trace the historical origins of cervical balloon dilation in labor induction.
• To highlight the significance of early warnings regarding materials used in cervical dilators.

Main Methods:

• A comprehensive literature search was conducted using PubMed, Google Scholar, and the University of Ryerson website.
• Key search terms included "Barnes", "Woodman", "balloon dilation", "balloon catheter", "foley", "colpeurynter", "cervix uteri", and "induction."
• Downloaded articles were analyzed using BibDesk for historical accuracy.

Main Results:

• The historical record indicates that Storer and Mattei, contemporaries of Barnes, should be credited with the origin of cervical balloon dilation for labor induction.
• Storer issued a warning about the rubber used in dilators, which was unfortunately ignored.
• This oversight may have contributed to preventable maternal deaths over several decades.

Conclusions:

• The attribution of cervical balloon dilation's origin requires revision, crediting Storer and Mattei.
• Early safety warnings concerning medical devices are crucial and should not be disregarded.
• Revisiting medical history can uncover critical lessons for contemporary practice and patient safety.
