Epidural Blockade
Conditions
Brief summary
The purpose of this study is to describe infrared thermographic imaging as a tool for the assessment of epidural block in obstetrics patients
Detailed description
Patients will recive standard anesthesia care for epidural placement and additionally, thermographic imaging will be obtained at baseline and up to 30 min after the epidural blockade is performed.
Interventions
Using infrared-recording camera will obtain thermographic images of the lower extremities before and after the epidural blockade

Eligibility
Inclusion criteria
* Parturients in active labor requesting epidural anesthesia for normal vaginal delivery
Exclusion criteria
* Patients with lower extremity skin disorders like active infections like cellulitis, ,dermatitis, psoriasis or connective tissue disorders like scleroderma or Raynaud's phenomenon * Patients with diagnosed peripheral vascular disease ,venous stasis , deep venous thrombosis. * Patients with Severe preeclampsia with significant lower extremity edema * Patient on vasoactive agents like vasodilators, calcium channels blockers.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in temperature in the lower extremities | at baseline, 5 min before the epidural blockade, during and up to 30 minutes after performing the epidural blockade | thermographic images of the lower extremities will be obtained and analyzed for thermography patterns. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Successful epidural blockade | up to 30 min after performing the epidural block | adequate sensory level, pain control, motor blockade as evaluated by care provider |
| Epidural blockade failure | Up to 30 min after performing the epidural block | Failure of the epidural block to adequately control pain, unilateral blockade, optimal sensory level, inadequate motor blockade |
| Requirement for Epidural catheter manipulation or replacement | Up to 30 min after performing the epidural block | — |
Other
| Measure | Time frame |
|---|---|
| Peri-procedural Complications | participants will be followed for the duration of anesthesia and after the procedure, an expected average of 12 hours |
