Details and patient eligibility

About

This is a data base building project on the use of pre-procedure ultrasound for the performance of labor epidural pain relief and spinal anesthesia for cesarean deliveries. Data collection includes ultrasound measured depth, actual needle depth, angle of ultrasound probe, actual needle angle, success rates, patient height and weight, number of attempts needed to place the epidural needle or spinal needle. Currently we are looking at the agreement between ultrasound determined depth of the epidural space or intrathecal space with actual needle depth.

Full description

All patients presenting in labor or are having a cesarean delivery are eligible except: patients who are under age 18, have contraindications to regional anesthesia, in advanced labor, having emergency conditions and/or unable to understand the consent process.

Data collected include:
Ultrasound depth in transverse and oblique sagittal views
Actual needle depth
Level of placement
Number of separate needle placements
Number of needle redirects
Angle of probe
Angle of needle
Total number of attempts
Pt height
Pt weight
Pt BMI
Pt age
Pt gravity/parity
Pt co-morbidities, e.g. pre-eclampsia
Procedure performed
Operator (Attending, CA-1, CA-2, CA-3, CRNA)

What is currently being examined is the correlation between ultrasound depth of the target area vs actual needle depth
