Plain English Summary
Background and study aims
Early mobilization after Cesarean delivery is encouraged to decrease blood clots (thromboembolic events) and shorten the length of hospital stay. Although postoperative pain management with epidural pain medication can perfectly fit the purpose, it might impair the capability of standing and walking due to epidural local anesthetics and opioids. The purpose of this study was to determine the safety and efficacy of different doses in epidural fentanyl in addition to local anesthetics while ambulation of those who had an elective Cesarean delivery.
Who can participate?
Any term pregnant woman with ASA I or II who undergoes an elective Cesarean delivery and receives an epidural catheter at T12/L1 following spinal anesthesia.
What does the study involve?
Participants will be randomly allocated to receive continuous epidural infusion of 0.2% ropivacaine containing either 2.5 mcg/ml (Group 1) or 5 mcg/ml fentanyl (Group 2) started at the rate of 5 ml/h after Cesarean delivery.
What are the possible benefits and risks of participating?
Possible benefits are encouragement of early mobilization after Cesarean delivery. Possible risks are falling during ambulation.
Where is the study run from?
Kobari General Hospital (Japan)
When is the study starting and how long is it expected to run for?
May 2018 to December 2019

Posturography can detect potential impairment of standing stability due to epidural fentanyl after Cesarean delivery
The objective of the current study is to compare standing stability measured by posturography between two different concentrations of epidural fentanyl in addition to local anesthetics in post-Cesarean delivery women with continuous epidural analgesia.

Spinal anesthesia during an elective Cesarean delivery
Continuous epidural infusion of 0.2% ropivacaine containing either 2.5 mcg/ml (Group 1) or 5 mcg/ml fentanyl (Group 2) is randomly assigned to an individual and started at the rate of 5 ml/h postoperatively.
Total duration of treatment (i.e., continuous epidural analgesia) was 48 hours after their Cesarean delivery. And the total duration of follow-up was up to 7 days after their Cesarean delivery. Participants were randomized into 2 groups by a table of random numbers.
Primary outcome measure
Sway area measured by a posturography at baseline, one and seven days after Cesarean delivery
Secondary outcome measures
1. Pain status with Visual Analogue Scale once a day after Cesarean delivery up to post-operative seven days
2. Motor function of legs with Bromage scale on post-operative day one
