Baseline characteristics by cohort

Baseline characteristics by cohort
Measure
Group 1 Catheter to Slight Traction
n=68 Participants
Once the decision was made to use a transcervical catheter and the patient was not in labor, the patient was approached. After informed consent was obtained from each participant, an 18 French 30 cc Foley bulb was placed digitally by the housestaff, with or without a stylette. The balloon was filled with 50 cc of saline as this is the standard at our institution. Patients randomized to tension had their catheter taped with applied tension to the inner thigh. Tension was replaced approximately every 30 minutes as needed. If the catheter was not expelled after12 hours, the balloon was deflated and the catheter was removed.
Group 2 Catheter to no Traction
n=76 Participants

The balloon was filled with 50 cc of saline as this is the standard at our institution. Patients randomized to no tension did not have any tension applied to their catheter. After randomization clinicians were not blinded to the allocated group. If the catheter was not expelled after12 hours, the balloon was deflated and the catheter was removed.
