The purpose of this study is to evaluate whether manual removal of the placenta during a cesarean delivery results in higher changes in the resistance of blood flow throughout the body, also called systemic vascular resistance (SVR)

Condition Intervention
Cesarean Delivery
Behavioral: Manual removal
Procedure: Expressed removal

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Manual and Expressed Placental Removal at Planned Cesarean Delivery and Its Effects on Various Cardiac Indices as Measured By Continuous Wave Doppler Ultrasonography

Further study details as provided by William Beaumont Hospitals:

Primary Outcome Measures:
  • Hemodynamic profile, especially Systemic Vascular Resistance [ Time Frame: immediately before and 24 hours after cesarean delivery ]

Secondary Outcome Measures:
  • development of postpartum preeclampsia [ Time Frame: within 1 week of delivery ]

Enrollment: 19
Study Start Date: July 2008
Study Completion Date: January 2012
Primary Completion Date: February 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: manual
Manual removal of placenta
Behavioral: Manual removal
Manual removal of placenta during cesarean delivery
Other Name: manual
Active Comparator: expressed
expressed placental removal
Procedure: Expressed removal
Surgeon will perform an expressed delivery of the placenta
Other Name: expressed

Detailed Description:

Patients presenting to William Beaumont Hospital Royal Oak Labor and Delivery for a scheduled low transverse cesarean delivery will be asked to participate in a prospective, randomized study to evaluate any changes in systemic vascular resistance (SVR) pre- and post-delivery.

After obtaining informed consent, the patients will be randomized to one of two groups: group 1 will have manual removal of the placenta at cesarean section and group 2 will have expressed removal of the placenta at cesarean section.

Both groups will have a pre-operative continuous wave Doppler evaluation and a post-operative continuous wave Doppler evaluation at 24 hours after delivery. Continuous wave Doppler evaluation will be used pre- and post-operatively to evaluate any changes in SVR.
