The hypothesis is that a combined spinal-epidural drug at refrigerated temperature will have a shorter period of pain relief than that maintained at room temperature. The temperature of the dose of medication will be measure with an infrared thermometer immediately prior (within 5 minutes) to administration.
Subjects will receive a combined spinal epidural medication as per standard of care to treat their labor pain; however, they will be randomized to receive either a dose maintained at room temperature (60-75 degrees F) or one maintained in a refrigerator (\~\<43 degrees F). Duration of action will be done by assessments of pain, vital signs, nausea, itching, bromage and fetal heart rate every 15 minutes until the subject requests additional pain medication to treat their labor pain.

Time
length of time in minutes the combined spinal epidural dose duration is calculated from the time of administration until the request is made for additional analgesia (\~1.5-3 hours) post dose. The subjects epidural is then dosed as per standard of care.
Time frame: up to 3 hours
Analgesia Onset-5 Minutes Post Injection
Time frame: from time of CSE administration
Analgesia Onset-10 Minutes Post Injection
Time frame: up to 3 hours
Analgesia Onset-15 Minutes Post Injection
Time frame: up to 3 hours
Pruritus
patients reporting pruritis at 30 minutes after CSE injection, self reported and measured on a scale of 0 (no itching at all) up to 10 (itching as bad as can be imagined)
Time frame: 30 minutes
