NCT02685696

Brief Summary

Objective: To investigate if the use of the newly designed Alexis O Retractor leads to improved intra-operative and post-operative surgical outcomes in the setting of planned elective Caesarean Sections. Study Design: This ethically approved study is designed as a prospective, randomized controlled trial in planned, first time Caesarean Sections with 200 patients randomized to either the Alexis-O Retractor group or the conventional group. Patients with wound healing problems, connective tissue disorders, insulin dependent diabetes, bleeding disorders, previous major abdominal surgery and chorioamnionitis are excluded. Outcomes include surgical site infection, intraoperative parameters such as tissue damage, postoperative analgesia requirements and patient satisfaction scores.

Outcome Measures

Primary Outcomes (1)

  • Incidence of surgical site infection in low risk women having a first time planned Caesarean Section using the Alexis O Retractor compared to the traditional Metal Retractor.

    6-8 Weeks after Surgery

Secondary Outcomes (24)

  • Application Satisfaction Scale Scores

    Immediate Postoperative

  • Removal Satisfaction Scale Scores

    On the day of Surgery (Day 0)

  • Post Operative Pain Scale Scores at Discharge

    On the day of discharge (3-5 days)

  • Post Operative Pain at 6 Weeks

    6 weeks post operative

  • Patients with Wound Dehisence at Discharge

    On the day of discharge (3-5 days)

  • +19 more secondary outcomes

Study Arms (2)

Alexis O Retractor

EXPERIMENTAL

Group 1 received the Alexis-O-Retractor at thet time of first Caesarean Section

Device: Alexis O Retractor

Metal Retractor

ACTIVE COMPARATOR

Group 2 received the traditional self retaining metal Retractor at thet time of first Caesarean Section

Device: Metal Retractor

Interventions

A newly developed abdominal wall retractor for Caesarean Section is the Alexis O Ring which is formed of 2 rings and a interconnecting plastic polyurethane sheath where the flexible inner ring is placed into the abdomen and where the rigid outer ring is rolled to create tension on the plastic sheath providing 360° abdominal wound retraction with simultaneously a tamponade effect whilst covering the abdominal wound during the Caesarean Section and delivery of the baby.

Alexis O Retractor

The traditional self-retaining metal Collins Caesarean Wound Retractor.
