Shivering during a cesarean section can be quite uncomfortable for the patient as well as make it difficult for the anesthesiologist to obtain vital signs. The researchers will investigate whether or not applying pressure to the P6 acupressure point during a cesarean section can treat shivering. The hypothesis is that shivering will be alleviated with acupressure.
The purpose of this study is to determine whether applying pressure to the left and right P6 acupoints can treat shivering in a patient undergoing a cesarean section. The hypothesis is that bilateral stimulation of P6 with pressure can stop or alleviate shivering.
The primary endpoint is resolution of shivering within 15 minutes of applying bilateral pressure to P6 acupoints during a cesarean section.
The secondary endpoints include:
Patient information will be stored in a locked cabinet on labor and delivery, and that cabinet will be located in a T3-locked office. The link between subject ID and patient ID will be stored in a different office on labor and delivery, also under a T3 lock.
Patients who are laboring with an epidural catheter and subsequently require a cesarean section will be selected. This patient population has a MUCH higher rate of shivering during the cesarean section as compared to patients who undergo elective scheduled cesarean sections under spinal anesthesia. By selecting this group, the investigators are not only increasing chances of identifying shivering but also decreasing variability between patient characteristics by limiting it to one type (only epidural and not spinal) and limiting the number of screen failures.

Once an obstetrician determines that a patient laboring with an epidural catheter should have a non-emergent cesarean section instead of continuing labor, the clinical anesthesiologist will contact the research team. A member of the research team will contact the patient while she is still in the labor and delivery room, at which time informed consent would be obtained.
