Study Details

Study Description

Brief Summary

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.

Detailed Description

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:
  1. Time to resolution of shivering

  2. Degree of patient-reported improvement in shivering

  3. Degree of practitioner-reported improvement in shivering

  4. Assessment of skin irritation and/or pain at the site of acupressure vs control

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.

Study Design

Study Type:
Interventional
Actual Enrollment :
43 participants
Allocation:
Randomized
Intervention Model:
Parallel Assignment
Intervention Model Description:
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.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.

Outcome Measures

Primary Outcome Measures

  1. Incidence of resolution of shivering at 15 minutes [up to 15 minutes]

    Incidence of resolution of shivering within 15 minutes of applying bilateral pressure to P6 acupoints during a cesarean section.

Secondary Outcome Measures

  1. Time to resolution of shivering [up to 15 minutes]

    Time to resolution of shivering

  2. Degree of resolution of shivering [up to 15 minutes]

    Degree of patient-reported improvement in shivering as measured by Crossley & Mahajan shivering scale: 0 = no shivering;1 = no visible muscle activity but piloerection, peripheral vasoconstriction, or both are present (other causes excluded); 2 = muscular activity in only one muscle group; 3 = moderate muscular activity in more than one muscle group but no generalized shaking; 4 = violent muscular activity that involves the whole body.

  3. Degree of practitioner-reported improvement in shivering [up to 15 minutes]

    Degree of practitioner-reported improvement in shivering as measured by Crossley & Mahajan shivering scale: 0 = no shivering;1 = no visible muscle activity but piloerection, peripheral vasoconstriction, or both are present (other causes excluded); 2 = muscular activity in only one muscle group; 3 = moderate muscular activity in more than one muscle group but no generalized shaking; 4 = violent muscular activity that involves the whole body.

  4. Number of participants with skin irritation [up to 15 minutes]

    Number of participants with skin irritation at the site of acupressure obtained by patient self-reporting

  5. Number of participants with pain [up to 15 minutes]

    Number of participants with pain at the site of acupressure obtained by patient self-reporting
