Brief Summary:

When a woman requires a cesarean section after labour, anesthesia is usually provided by a pre-existing epidural. Occasionally, the epidural does not work. The anesthesiologist then may give a "spinal anesthetic". The spinal space is identified by seeing cerebrospinal fluid (CSF) in the spinal needle. Rarely a spinal fails after a failed epidural as the fluid seen is epidural space fluid, not CSF. This study plans to use a bedside glucose monitor to measure glucose (sugar) in epidural fluid (compared to CSF) allowing the anesthesiologist to know the spinal needle is in the correct space.

The investigators hypothesize that a bedside glucose measurement device can accurately quantitate the level of glucose within epidural space aspirate, and therefore could aid differentiation between CSF and epidural fluid.

Group/Cohort
Labouring woman with epidural in situ
Any healthy English-speaking pregnant woman in labour who has received an epidural for pain relief



Primary Outcome Measures :
  1. To confirm that the glucose meter is a feasible and accurate bedside method to detect glucose in epidural aspirate and to use glucose to differentiate CSF from epidural aspirate in women with pre-existing epidural catheters. [ Time Frame: Between 2-24 hours after labouring woman has an epidural placed for her labour ]
    Descriptive statistics outlining the range, central tendency (mean, median), and variability (standard deviation) for epidural glucose will be presented, and these figures then compared to those obtained from the Sweet CSF study.


Secondary Outcome Measures :
  1. Influence of other factors on epidural glucose [ Time Frame: Between 2-24 hours after labouring woman has an epidural placed for her labour ]

    Paired t-tests will be conducted to compare epidural glucose levels, blood glucose levels and the influence of the following on the glucose concentration within the epidural aspirate:

    1. Glucose ingestion
    2. Intravenous administration of glucose containing fluids
    3. Disorders of glucose metabolism
    4. Length of time that the epidural catheter was in situ
