The purpose of this study to investigate whether using a special warming blanket during Cesarean delivery helps maintain a normal body temperature in the baby when compared to mothers that are not warmed (standard care at BC Women's Hospital). Doctors observed that some babies have low body temperatures when they are born by Cesarean delivery. Since baby temperatures are dependant on the temperatures of their mothers, we believe that keeping the mother warm during surgery with the use of a special warming blanket that is filled with warm air will result in the baby being warmer at birth.

Primary Outcome Measures:
  • Neonatal axillary temperature at delivery [ Time Frame: During delivery ]

Enrollment: 70
Study Start Date: February 2008
Study Completion Date: July 2008
Primary Completion Date: July 2008 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active warming with Bair Hugger blanket
Procedure: Active warming with Bair Hugger blanket
Standard care at BC Women's Hospital plus a Bair Hugger full access underbody blanket model 635 (Health Canada Licence # 12692) warmed by Bair Hugger temperature management unit model 750. Patient will lie on the underbody blanket and it will be turned on once patient is supine on operating table following the insertion of anesthetic. The warming device will be set to the medium temperature setting (380C). Warming will continue until the end of surgery unless otherwise requested by the mother.
