简要总结
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.
详细描述
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

结局指标
主要结局
Correlation of Ultrasound vs Needle Depth
时间窗: Beginning of ultrasound exam to end of ultrasound exam: average 5 min
The ultrasound measured depth taken via oblique sagittal views and transverse views of the epidural space for epidural analgesia or intrathecal space for spinal anesthesia will be correlated with actual needle depth
次要结局
- Attempt Number(Beginning of placement of epidural or spinal needle to end of placement: average 10 min)
