Epidural analgesia remains the gold standard for pain control during labor and delivery. Proper assessment of an epidural's level of blockade is important for providing safe and effective analgesia. Previous studies have established that the most commonly tested modality for adequacy of epidural blockade is a patient's sensory blockade to cold temperature. In a study performed at our institution, Soares et. al. (publication pending) documented two thresholds of sensory block to ice: one defined as the lower sensory block level, in which the patient is able to notice the cold sensation but perceives that it is not as cold as a control dermatome; the other defined as the upper sensory block level, in which the patient perceives that the cold sensation is at approximately the same temperature as if it were applied to a non-anesthetized area such as the neck or face. Although this a known finding to nurses and physicians assessing the sensory block to ice, this phenomenon and its magnitude has not been previously reported in epidural anesthesia. The goal of this study is to examine patients with labour epidurals and to determine the dermatomal relationship between the lower and upper sensory block levels to cold when compared with sensory blockade to both pinprick and light touch.

Exclusion Criteria:
Sensory block level check Patients will have their sensory block level checked using 3 modalities: ice, pin prick and soft touch (cotton ball).
Lower sensory block level: ice test
The lower sensory block level to ice, defined as the dermatome at which there is a complete loss of cold perception.
Time frame: 5 minutes
Upper sensory block level: ice test
The upper sensory block level to ice is defined as the dermatome at which there is an altered cold perception without complete sensitivity loss.
Time frame: 5 minutes
Lower sensory block level: pinprick test
The lower sensory block level to pinprick, defined as the dermatome at which there is a complete loss of sharp sensation.
Time frame: 5 minutes
Upper sensory block level: pinprick test
The upper sensory block level to pinprick is defined as the dermatome at which there is an altered sharp sensation without complete sensitivity loss.
Time frame: 5 minutes
Sensory block level: soft touch test
The sensory block level using soft touch is defined as the dermatome below which the patient can feel a light touch.
Time frame: 5 minutes
Motor block score using Bromage score
Motor block will be assessed with the Bromage score: 0 = able to raise the extended leg; 1 = unable to raise the extended leg but able to flex knees; 2 = unable to flex knees, but able to flex ankle; 3 = unable to flex ankle.
Time frame: 5 minutes
