Comparison of Two Anatomic Landmarks With Ultrasonography in Spinal Anesthesia
- Conditions
- Arthropathy of Knee
- Interventions
- Device: ultrasonography
- Registration Number
- NCT02330185
- Lead Sponsor
- Diskapi Yildirim Beyazit Education and Research Hospital
- Brief Summary
The most used anatomical landmark for application of spinal anesthesia is Tuffier's line. Other alternative landmark is tenth rib. However there is no trial that compare these landmarks based on using ultrasonography.
- Detailed Description
The investigators aim to compare two landmarks (Tuffier's line and tenth rib line) for accuracy by using ultrasonography. 40 patients will be included in each groups. all of them will be assessed by ultrasonography during application of spinal anesthesia. And the investigators will examine the percentage of successful estimation of correct vertebral space.

Group Intervention Description spinal anesthesia for knee arthroscopy ultrasonography The intervention is spinal anesthesia. Tenth rib line or Tuffier's line will be examined as application landmarks by ultrasonography for spinal anesthesia.
- Primary Outcome Measures
Name Time Method success of estimation the correct vertebral space 2 months Independently, first anesthesist will determine the spinal anesthesia application point (intervertebral space) according to Tuffier's line and second anesthesist will determine it by ultrasonography. And third anesthesist will compare the accuracy of first determination.
