Study Using Fluid Warming and Forced Air Warming Immediately Prior to and During Elective Cesarean Section

During surgery body temperature can decrease which can adversely affect how people recover from surgery. This is a common problem. We aim to reduce the incidence of this drop in body temperature during surgery by testing the effectiveness of two active body warming devices. One method is to warm the intravenous fluids that the patients will receive, as they are being infused. The other method is to use a forced-air warmer. This is a device that is similar to a blanket that the patient has laid over their upper body during the surgery which has warm air blown into it. The control group will not have any active warming methods. Study group 1 will have the intravenous fluid warmer in the pre- and intraoperative period. Study group 2 will have a forced-air warmer in the intra-operative period as well as the fluid warmer in the pre- and intraoperative period. We will also observe the neonates' vital signs following delivery.

Stanford is now accepting new patients for this trial.
