Brief Summary:
The combined spinal epidural (CSE) technique has become increasingly popular for labor pain because of its rapid onset and superior first stage analgesia. However, increased risk for early profound fetal bradycardia (EPFB) following CSE continues to be a concern. Various factors are implicated in the etiology of EPFB but the cause is unknown. Ephedrine administration prior to CSE analgesia may help reduce the risk of EPFB, but to date, nobody has studied the impact of a single dose of intravenous (IV) ephedrine given at the time of CSE administration during labor. The purpose of this study is to measure the incidence of EPFB after combined spinal epidural analgesia using standard definitions. The incidence of EPFB will be compared between patients who receive prophylactic ephedrine or placebo at the time of CSE placement.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 710 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Prevention
Official Title: Prophylactic Ephedrine to Reduce Fetal Bradycardia After Combined Spinal Epidural Labor Analgesia: a Randomized Double Blind Placebo-controlled Study
Study Start Date : January 2012
Actual Primary Completion Date : April 2013
Actual Study Completion Date : October 2013


Arm Intervention/treatment
Active Comparator: Prophylactic ephedrine
Ephedrine 10mg iv once at time of combined spinal epidural insertion
Drug: Ephedrine
Patients received additional doses of ephedrine 10mg IV to a maximum of 30mg if BP remained low (<90mmHg systolic) and/was associated with persistent fetal bradycardia or maternal symptoms of dizziness and nausea

Placebo Comparator: Normal saline (placebo) control group
1ml normal saline intravenously once at time of combined spinal epidural insertion
Drug: Placebo
Patients received normal saline (placebo) administered immediately after combined spinal epidural (CSE) placement




Primary Outcome Measures :
  1. Early Profound Fetal Bradycardia [ Time Frame: Within 30 minutes of combined spinal epidural (CSE) placement ]
    Incidence of early profound fetal bradycardia


Secondary Outcome Measures :
  1. Tetanic (Sustained) Uterine Contraction (TUC) [ Time Frame: Within 30 minutes of combined spinal epidural (CSE) placement ]
    Incidence of Tetanic (sustained) Uterine Contraction (TUC)

  2. Urgent Cesarean Delivery [ Time Frame: Within 30 minutes of combined spinal epidural (CSE) placement ]
    Incidence of urgent cesarean delivery
