Assessment of Pain With Insertion of the Foley Catheter for Induction of Labour

This study has been completed.

Uppsala University Hospital Identifier:
First received: November 4, 2010
Last updated: August 10, 2011
Last verified: August 2009
The purpose of this study is to assess pain in women randomised to digital or speculum placement of a Foley catheter. Pain during cervical ripening with the Foley catheter is also to be evaluated as well as maternal satisfaction with induction of labour.

Condition Intervention
Device: Foley catheter

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment

Further study details as provided by Uppsala University Hospital:

Primary Outcome Measures:
  • Pain assessed by VAS and SCA, in women randomised to digital or speculum placement of a Foley catheter. [ Time Frame: At insertion of Foley catheter ]

Secondary Outcome Measures:
  • To assess pain with VAS and SCA during cervical ripening with the Foley catheter and to evaluate maternal satisfaction. To evaluate if markers of stress in blood and amniotic fluid correlate with VAS and SCA. [ Time Frame: During treatment with Foley catheter. At expulsion of Foley catehter ]

Enrollment: 42
Study Start Date: August 2009
Study Completion Date: October 2010
Primary Completion Date: August 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Digital
The patient was randomized to digital insertion of the Foley catheter
Device: Foley catheter
The Foley catheter was placed with the digital method
Experimental: Speculum Device: Foley catheter
The Foley catheter was placed with a speculum

Detailed Description:

The most common method described for placing the Foley catheter is under direct visualisation of the cervix during a sterile speculum examination. Another method is to place the catheter during a digital cervical examination.

Maternal discomfort/pain during speculum placement of the catheter has been evaluated in a few studies whereas studies that compare the digital method with the speculum method of placement are lacking.

The visual analogue scale is used to subjectively assess pain. With a skin conductance algesimeter an objective assessment of pain is possible.
